At the beginning, I traveled through the wilderness, and I controlled the beasts to survive...

Chapter 189 The creature carrying the treasure

Leon looked around at the dark, dark, deserted gravel land with sparse vegetation, and said:

"If there is a coal mine with relatively abundant reserves here, we don't have to look far away to design a geothermal power station. We only need to build a small thermal power station close to the college to meet the electric energy needed for daily life and production."

"Mr. Lyon, approximately how much coal reserves are needed to meet our needs?"

"It depends on everyone's specific development plans...but I estimate that as long as there is a coal mine underneath, no matter how big or small, it can basically meet our needs."

After that, the few people said nothing and waited quietly for the rock-breaking ants to appear.

About ten minutes passed.

Egg Pancake, who had been lying on the ground and was responsible for detecting the surrounding situation, suddenly raised his head and gave Han Ning a soft "chirp".

At the same time, Han Ning also felt the ground beneath his feet begin to vibrate slightly.

After a few seconds, even the people around him felt a slight movement under their feet.

"Yinyi, pay more attention. If other creatures come out, don't hesitate to tie them up."

On the other side, without Han Ning's reminder, Dean Wu looked solemn and only said two words to his tree spirit: "Be alert!"

Every time the exploration team returns, a little of the loot will be distributed to help some "old, weak, sick and disabled" teachers and students in the academy to cultivate soul beasts so that they have certain combat capabilities.

As the "brain" that directs the normal operation of the entire college, Dean Wu rarely goes out to explore, but he is allocated a lot of resources.

His Anemone also successfully evolved into a heavily armored tree spirit some time ago.

"Rust~"

Three 2-meter rock-breaking ants rushed out of the ground from three directions: north, east, and west, hundreds of meters apart.

Just after they rushed to the surface, within a few seconds, their round heads popped out of the gravel like gophers emerging from the ground.

Silver Ripples, who had been waiting above for a long time, immediately waved the densely packed vine whips, making a "pop" sound in mid-air. The sharp sound of breaking through the air tied up the round sticks that poked out of the ground with lightning speed. head.

"Ling~"

Yin Yi swung the vine whip and pulled out the five heads.

As it was pulled out for the first time, fine cracks began to appear in the surrounding ground.

But those heads seemed to be connected to the earth, and Yin Yi didn't even pull them out with the first blow.

"Woo~woo~"

The tied round heads were in pain, and whimpering sounds came from inside their heads. They all opened their mouths and sprayed large amounts of thick black smoke at the silver ripples.

"grumble!"

When Omelette saw this, she snorted immediately, and little red sparks spattered out of her nostrils.

Huhu~

A torrent of surging crimson flames spurted out from its mouth, instantly burning away the thick black smoke.

"Ling!"

Yin Yi's eyes flashed with flames, and she flew into the air. The vines she shot shook violently, and she pulled it up again!

Suddenly, the ground shook slightly, and large areas of the land surface cracked. Then, figures, large or small, appeared in the sight of the four people with splashes of soil.

These creatures look very similar, and it can be seen that they are all of the same race.

They have heads shaped like turtles, with the surface covered with densely packed black rock particles. The turtle shells on the back are not round and arc-shaped as Han Ning imagined, but are inlaid with strips like "peaks" that stand upward. Small black stones rise and fall like mountains on the earth.

These stones wrap their relatively fragile bodies like a stone "turtle shell".

Four thick feet that were like stone pillars were dangling in the air.

If it lies still, it looks like large black rocks.

"turtle?"

Han Ning blinked, but his eyes stayed on the undulating black rock pillars on the backs of the turtles.

These irregularly protruding rock pillars, accompanied by the shaking of the body owner, are still dropping black residue downwards.

Looking at the stone that was almost the same color as coal, Han Ning's expression changed: "Could it be that...the stones on this back are all coal?"

Not only him, but several people next to him also discovered this at the same time.

Everyone invariably focused their attention on the backs of the turtles.

Han Ning directly asked Yinyi to break some stone fragments from the back of a turtle and roll it in front of him.

The egg cake on the side spurted out a burst of ordinary sparks, trying to ignite the stone flakes.

After being wrapped in orange flames for a while, the surface of the almost pure black stone began to light up with red spots, and streaks of light blue flames rose up.

"It's really coal..." Han Ning sounded surprised.

Leon looked at the quietly burning stones wrapped among the vines and said: "It's not just coal, it may be higher quality anthracite. Have you noticed that it has a higher ignition point and burns relatively fully."

"A turtle that can produce high-quality coal... isn't it a bit similar to a crude oil oakworm? It's an eye-opener."

Han Ning sighed as he looked at the turtles of various sizes not far away that were struggling but unable to escape Yin Yi's control.

They are not the same as crude oil oak worms. The excrement excreted by crude oil oak worms has the same properties as crude oil. Turtles carry coal on their backs, or it can be said that coal grows on their backs.

From the extent of their struggle, Han Ning could also tell that these turtles were not very strong, and they could not display some relatively powerful soul skills. They were just relatively large, but...looking at their size, it was impossible to rely on strength alone. A collision would probably kill the soul beast at once.

The smallest one is at least 3 meters long, and the largest one is close to 10 meters. In addition, there are a bunch of stacked rock pillars on the back, which are like a hill. No wonder Yinyi didn't remove them from them all at once. Pulled out of the ground.

Dean Wu seemed to have discovered a rare treasure. He looked at the struggling turtles in front of him with interest and said slowly: "Interesting, we will take a few back to study later. Maybe they can help us a lot." .”

"In addition to these black turtles, three rock-breaking ants collected coal 500 meters away and nearly 600 meters deep, indicating that there are at least more than 500 million cubic meters of coal reserves in this area."

Five million cubic meters is only a small area of ​​exploration discovery. Han Ning does not know the specific amount for the time being.

But at least, such a large amount of coal reserves is enough to support a college with hundreds of people for a period of time.

After initially confirming the existence of coal mines in this area, Han Ning directed Yinyi to knock out several turtles, take them all away, and return to the academy.

……

Return to the academy.

After handing the detector to the old professor, Dean Wu, Leon and his daughter, together with several teachers, were busy studying the black turtle. Han Ning was going to go back and rest for a while. He had used magic earlier to increase his mental and physical strength. A lot of consumption, now people are a little tired.

<divclass="contentadv">F floor.

At this time, the internal space of this dormitory building has been opened up by Yinyi and Egg Pancake, and it is empty like a large factory building.

"Gee~"

Han Ning's living area only occupies a small area on the first floor. The rest of the area is covered with dry grass leaves, and the egg cake rolls around comfortably on the grass leaves.

Yinyi, on the other hand, was lying on Egg Pan's back, crossing her legs comfortably.

"Jeep!"

When Han Ning lay on the bed, he was about to take a nap.

Omelette carefully held a tablet computer with the tips of her claws, moved over, and leaned her huge head against Han Ning's bed.

The small computer is on its paw, and it looks smaller than a sesame seed.

"What's wrong?" Han Ning looked sideways at the big head, which was taller than several floors, and smiled.

"Ji!" Egg Pancake moved the small tablet over and called Han Ning twice.

"You want the All-Seeing Silkworm to come out? Why are you looking for it?" Although he asked this, he still made the All-Seeing Silkworm turn into an exquisite little egg pancake and fly in front of the big egg pancake.

"grumble!"

The moment he saw the Vientiane Spiritual Silkworm, Omelette's eyes lit up, and a very thin stone stick with a round surface formed from the tip of his claws. He skillfully unlocked the screen and clicked it a few times.

Then, a two-dimensional picture of a cute little female dragon wearing a black and white maid uniform appeared on the screen.

"Chichi, chichi!" Egg Pan pointed at the little female dragon on the screen and chirped at the All-Seeing Silkworm.

"Jiji?" Wanxiang Lingsi was confused and probably knew the meaning of the egg cake.

Then... under Han Ning's strange gaze, its body began to change.

The plump purple body, the curved little horns, the small wings...

Not long after, a cute little female dragon with a shy expression and fluttering wings blinked and flew to the egg pancake, sticking to its body.

"Chi, chi chi, chi~" The corner of Omelette's mouth almost reached the back of her head. She hugged the little female dragon transformed from the all-powerful silkworm and kept chirping.

"...Egg...Egg Pancake, when did you become a crazy dragon?!" Han Ning was surprised and amused when he saw Egg Pancake enjoying himself.

The innocent and pure egg cake at the beginning has been spoiled by all kinds of gadgets on the mobile phone!

"Jiji..." Omelet heard Han Ning's voice and called out a little aggrievedly.

He said that on days when it rained and he couldn't go out, he spent his days watching these cute little female dragons on his mobile phone.

"emm... My fair lady, a gentleman is a gentleman, there is no problem..."

"Jiji!" Hearing this, Egg Pancake explained repeatedly that it only likes the two-dimensional cute little dragons on the mobile phone, and does not like the big female dragons that are big and thick in real life!

...

Night, conference room on Building A.

"In the afternoon, Han Ning and I, as well as Mr. Lyon and Lisa, went to the wild together... where we discovered a coal mine and a strange spirit beast." Dean Wu sat behind the table. Briefly state the purpose of this meeting,

"After half a day of research, we have a preliminary understanding of this kind of turtle. Please ask Mr. Lyon to explain it to us."

He stretched out his hand and pointed at Leon, who was sitting not far away.

"Please allow me to occupy the projector for a moment."

Leon nodded to everyone, took out a USB flash drive, inserted it into the computer that controlled the projection, and opened a PPT file.

When the ppt is played, the first picture shows a black turtle lying on the floor, looking weak.

"This is a spirit beast that lives in coal mines. I call it the Black Stone Turtle."

As he spoke, he pressed the remote control and the ppt played to the next picture.

It can be seen that the second picture is still the black stone turtle in the previous picture, but the "little" guy in the picture no longer looks sluggish, but is happily devouring a ball of three-eyed worm meat passed by Leon. .

The picture just freezes here.

"Originally we thought that black stone turtles depend on coal for food. Without coal, their bodies will become weak and unable to move."

"However, after our scientific researchers conducted various tests on it, we found that even if it takes three-eyed worms, the black stone turtle can still recover its physical strength, but the recovery rate of physical strength will be slower than that of the ordinary black stone turtle that eats coal."

On the ppt, there is a statistical chart showing the consumption of various foods by two black stone turtles of the same body type and about the same size.

Just eating coal or pureed meat will not restore your physical strength the fastest.

The fastest was the black stone turtle that ate coal + meat paste. Its physical recovery speed was nearly 1.2 times faster than that of the black stone turtle that only ate coal. Putting the two together, the vitality displayed was obviously different.

"We originally thought that the black coal on the black stone turtles was coal that they constantly collected in nature and grew on their bodies after eating."

"This is indeed true. What surprised me is that black stone turtles can actually grow black coal after eating meat paste!"

From the capture of the Black Stone Turtle to now, the time interval is relatively short. Two comparison pictures on the left and right appear on the screen. The picture on the left is the back of a Black Stone Turtle, a corner where relatively no coal grows.

In the picture on the right, there are small black particles growing in the corner.

"This is really a surprising discovery. It means that in the future, as long as we feed them a certain proportion of coal plus blood food, we can harvest a steady stream of high-quality coal from the black stone turtles."

"Everyone knows that turning open-pit coal mines into various raw materials needed for our lives, such as coking coal, coal tar, and liquefied coal, requires relatively complex screening, impurity removal, and processing techniques. With high-quality coal, we This will save you these processes.”

"Why is it said that the coal on the Black Stone Turtle is of high quality? The following is a series of combustion test data on ordinary anthracite coal and coal taken from the Black Stone Turtle."

Leon pointed at the data form with an infrared pen and said,

"As you can see, the coal on the Black Stone Turtle is more than 1.3 times that of ordinary anthracite in terms of burning time and degree of burning. Although the improvement is not much, it is at least a 30% improvement."

"In other words, we can regard the Black Stone Turtle as a moving mountain of high-quality coal."

As we all know, thermal power generation is actually about boiling water. Through heating, the water is turned into high-temperature water vapor to drive the steam turbine to generate electricity.

“With high-quality, fully burned coal, we can undoubtedly greatly increase energy usage!”

The more Leon talked, the more excited he became. His excitement also infected everyone present. Even Lu Xiuning, who had a calm expression, couldn't help but look serious.
