Doomsday Sacrifice

88 Collision
Sure enough, sacrificing books is the kingly way.

This less than an hour of sacrifice allowed Li Xun to get dozens of rewards, more than all the rewards he got a few days ago combined.

Most of these rewards are blueprints and knowledge, and none of them can be directly used to improve strength.

This made Li Xun slightly disappointed.

In addition, the system evolved again, consuming [-] points of energy to evolve to the fourth level.

After the evolution, the system has a new function again, which seems to be related to synthesis, but Li Xun didn't have time to take a closer look, and he made a major discovery as soon as he reached the fifth floor.

aurora!

Like a dream, the ever-changing bright aurora fills the entire space on the fifth floor.

Li Xun's pupils shrank suddenly. The appearance of the aurora meant that the extreme energy concentration here was extremely high. The extreme beasts used this to invade the blue star through the wormhole. Now that the aurora is seen again, does it also mean that the wormhole may be opened again?
He immediately ran the genetic evolution method, and instantly sensed that the north building of the main building was covered by extreme energy from the fifth floor to the top, and the concentration of extreme energy increased as it went up.

What's even weirder is that the extreme energy is only found in the North Tower, and there is no leakage, as if there is an invisible big hand that binds the energy here.

With a movement in Li Xun's heart, an energy core was condensed immediately. As soon as it formed, the surrounding energy was frantically attracted to it, and it instantly turned into an energy ball the size of a ping-pong ball.

In just a short while, a hundred units of energy were absorbed, the concentration of extreme energy in the space on the fifth floor dropped significantly, and the aurora was faintly visible.

Li Xun was both surprised and delighted.

The good news is that there is enough extreme energy here, and the concentration is enough. It doesn't need to condense into energy balls, just absorb energy to evolve. If you absorb all the extreme energy here, you may be able to evolve two or three times at once.

What is surprising is that there is enough extreme energy here. Not only are there seven extreme beasts guarding the outside, but the extreme beast on the podium is likely to have a higher level of evolution than other extreme beasts.

The outside is already like this, not to mention the inside, which is even more dangerous here.

At this moment, his worries were fulfilled.

There was an extremely slight sound from the stairwell, like the breathing of some large creature after running.

Li Xun turned his head to look, and saw a monster the size of a cheetah coming down from upstairs, which was clearly a small beast.

He calmly took the hunting bow in his hand, and stretched his hand to the quiver. Although his face was still calm, his heart was in his throat.

"Extreme beasts are born from eggs, and can only reproduce twice in their lifetime. The first time they reproduce, they produce 20 to 30 eggs... The juveniles evolve into different types of mature bodies according to the environment..."

A systematic description flashed through his mind, and his body slowly retreated.

The middle of the floor on the south side of the main building is full of offices, surrounded by zigzag corridors, and there is not much space.

As the small polar beast entered the corridor, more and more figures of similar size appeared behind it. Li Xun stepped back and counted, there were thirty in total, one was quite a few, and the corridor was crowded to the brim.

He had already retreated to the corner, with the wall behind him, and his heart sank to the bottom of the valley.

There are not thirty identical polar beasts on the opposite side. Although they are similar in shape, their appearances are completely different. Apart from the four different polar beasts, there are at least six or seven different types.

Some have triangular heads, some have six legs, some have wings on their backs, and some have spikes like a hedgehog.

It looks very much like the legendary dragon who gave birth to nine sons, but the sons are different.

The nearest polar beast with a disk on top of its head was less than 20 meters away from him. Li Xun took a deep breath and suddenly let go of his right hand.

Arrows are like lightning.

The polar beast in front lowered its head, and the omnipotent barbed-fin arrow hit the disc on its head with a "ding" and bounced to the side.

Li Xun gasped, and ran away.

The polar beast behind him roared and chased after him.

While running desperately, Li Xun was thinking about the way out. He couldn't go downstairs because there were polar beasts guarding him outside, so he could only run upstairs.

Pass through the diamond-shaped lounge between the two main buildings and enter the north corridor, which has the same layout.

When he entered the stairwell and came to the platform between the two floors, Li Xun slowed down, glanced back and shot an arrow.

This time it hit the head of a four-faced beast, and it fell to the ground without even making a sound.

This unexpected attack attracted roars and two spikes from the little polar beasts.

The spikes shot from the back of that hedgehog-like polar beast were extremely fast and arrived in a flash. Li Xun, who was caught off guard, tried his best to avoid it but was still rubbed in his ear, which made him break out in a cold sweat.

He didn't dare to stay any longer, he went straight up the stairs and entered the twelfth floor.

This is the study room, except for the messy desks and chairs, there is only the steam-like aurora.

Li Xun quickly glanced at the room, and ran straight to the small stairwell in the middle, which leads directly to the cabin on the roof.

More than 20 small polar beasts have chased to this floor, and wolves swarmed into the room.

At this moment, Li Xun, who had just rushed to the top of the building, suddenly paused and stopped at the stairs.

He only felt his eyes go dark, as if his body had entered another space, and the space was filled with dazzling streamers of light.

And he was like a small boat in a violent storm, constantly swaying in the stream of light, as if it would capsize at any moment.

Time stopped at this moment, and even thinking stopped.

I don't know how long it has passed, but when Li Xun opened his eyes again, the first thing he saw was a strange thing.

It looks like a big mushroom, the bottom is rooted on the floor, and it can overflow from the mushroom umbrella like streams.

I'm afraid this is what the extreme beast wants to protect.

It was obviously not the time to take a closer look. Li Xun turned his head and looked down the stairs. Those little polar beasts were just wandering around the lower floor, showing no intention of coming up.

Surprised, he turned his attention to the big mushroom again. What is this thing? Even the polar beasts dare not approach it.

He didn't dare to act rashly, and slowly walked towards the door leading to the roof platform.

Opening the door, a breeze came in, and Li Xun walked out.

After going out the door, seeing that nothing unusual happened, he finally breathed a sigh of relief. This is the south main building. Looking down from the edge of the roof, he could see a few polar beasts downstairs.

The drone, which had had several batteries replaced, apparently spotted him, circling overhead.

Li Xun waved his hand at the camera, and Lao Fan and Shen Yiqing breathed a sigh of relief.

After hesitating for a while, between going and staying, he chose the latter, but before continuing to explore the big mushroom, he had to do one thing first.

Li Xun stood on the edge of the roof and began to run the genetic evolution method. Like a long whale sucking water, the extreme energy in the hut poured out, wrapping his body, and he completed the fourth evolution in a few seconds.

But the moment he completed his evolution, the beasts downstairs all went mad, and the beast on the podium let out an extremely angry roar, jumped up and walked along the side of the main building towards the building. Climb to the top.

Every time the huge body was caught on the building, it made a rumbling sound, and the broken glass and stones flew, the momentum was extremely astonishing.

Li Xun looked down, his gaze was like lightning, and he jumped down without hesitation, with a clearly visible, mysterious streamer behind him.

A dazzling lightning flashed across the sky.

There was a sudden thunder.

A man and a beast crashed into one place.
