You won’t be afraid if you learn mathematics, physics and chemistry well and cultivate immortality

The night passed without finding any tips, but as soon as I flew back to my courtyard, I heard some good news.

Murong Wan'er finally woke up after seven days of sleeping.

The group of little carrot heads screamed happily "Ao Ao Ao" and danced.

This is their teacher and their eldest sister. After spending more than half a year together, we have become like a family.

Autumn singing cicada is really powerful, Murong Wan'er's voice sounds very pleasant to the ear, just like the chirping of oriole in spring, it is very pleasant to hear.

The happiest thing is the hammer, which is the object of his heart.

As soon as Iron Hammer is happy, those little cuties in Cangwu Ridge will be unlucky.

At noon a stag and two wild sheep were hammered.

All the deer blood and velvet antlers must have been left for Murong Wan'er to nourish her body. In order to thank Ma Yumei for her careful care, the hammer struck her again.

Very generous, all good things, all kinds of agate jewelry.

The eldest sister Ma Yumei was so shocked that she hurriedly waved her hands and said, "No, I can't. This is what I should do."

The hammer replied firmly: "This must be accepted. It is both a reward and a fulfillment of the promise."

Tie Zhu on the side said "Hey hey hey." He just giggled.

Musk made a reasonable guess that these things were probably given by Tie Zhu through the hands of Iron Hammer.

Look at this posture, if you fall into that river, you probably won't be saved.

Of course, he was also obviously aware that the friends around him still felt a little alienated from their respect for him.

It's not as intimate as the previous one where the dog boy barked one at a time.

I don’t know when my identity started to change.

I have ignored this layer of relationship, and now my relationship with them does not feel as close as the relationship between Murong sister and brother, Zhao Yun and these friends.

Maybe it is really the difference between immortals and mortals, and the difference in status created today's ending.

In order to get closer, Musk also tried to lower his profile and wanted to integrate into the group again, but he always fell short.

Once you miss something, you really miss it, and it will never be as pure as when you first came back.

Even his grandfather is polite to him now.

What can I do?

Musk really feels a little powerless.

After all, people are emotional animals, and since they are unable to change, let's just be honest and do the present.

A thought flashed through my mind.

It is very simple to fly into the sky as a cultivator's weapon, but mortals can only think about it.

When these friends knew that they were immortal cultivators, they must have thought about flying to the sky with them to experience it.

But no one made such a request, and he didn't know why.

Maybe it's caused by this so-called identity difference.

Since I can't take you to fly, I can make and use tools to take you to the sky.

In fact, the idea that flashed through Musk's mind was to build a large hot air balloon.

The class representative said: The working principle of a hot air balloon is based on the principle of thermal expansion and contraction. When air expands when heated, its specific gravity becomes lighter and it rises upward. A hot air balloon uses fuel to inject hot air into the air bag, causing the hot air to gather in the air bag to generate upward lift. The large air bag will drag the hanging basket into the air together. Of course, the gondola can carry passengers, fuel and heat sources.

Remember! ???The air bag must be made of high-temperature-resistant and fire-resistant materials, otherwise a high-altitude free fall event is very likely to occur.

Of course, this risk factor is definitely relatively high.

Musk took out a pen and paper and began to calculate the size of a hot air balloon that can carry 3 to 5 people.

To calculate the approximate data through the air buoyancy formula, you need to fiddle with a spherical air bag of about twenty meters.

The two old men looked around curiously from time to time.

Although they couldn't understand it, after spending so long together, they knew they were going to mess with things again.

As Musk's biggest fans, the two veterans are loyal fans and are looking forward to his new ideas.

After he calculated the approximate data, Tie Hammer couldn't wait to ask what he was planning to do?

Musk did not hide it and introduced the new thing of hot air balloons to everyone.

And the uses and prospects of hot air balloons.

The friends in front of me all widened their round eyes when they heard that, and they all couldn't believe it.

Since you don’t believe it, I’ll show it to you.

Musk is also very simple, just find bamboo and paper.

With the help of two veterans, a simple version of the Kongming Lantern was made out of paper.

Everyone is curious, can this fly?

Musk didn't keep everyone's expectations for too long. He walked to the open space in the yard and lit the pine tar in the middle.

Heat slowly filled the big lantern, and it gradually swelled.

As it started to lift off the ground, Musk's hand slowly relaxed, and the Kongming Lantern slowly flew upwards.

This magical scene shocked all the friends without blinking, for fear that they would miss the important scene.

And the Kongming Lantern drifted further and further away with the spring breeze.

Musk said to the two veterans, if we make one big enough, it will definitely be able to fly.

It makes sense. The two veterans quickly asked how to do this?

Then he took out pen and paper and started sketching. He said he would sew a skin bag as big as a house to hold the heat.

The two veterans said directly that it was easy.

Let's go and catch the monster. The skin is strong and can withstand high temperatures.

When Musk heard it, what he said made sense and he couldn't refute it!

Although the three Hanhan were reckless, they were not stupid at all. There were many powerful monsters in Cangmang Ridge. They carefully observed and groped forward.

He even resorted to a big weapon and used the huge astronomical telescope to search for the target.

Fortunately, we didn't see any powerful monsters this time, but found a group of low-level black iron bulls.

"That's it." The three decided in unison.

Moo moo~ Niu Niu has pissed you off! ?

The three of them surrounded the herd, and the one who was very efficient killed five of them in one go.

Including the courageous leader who ran for his life to protect the tribe.

The harvest is full, and the skins of five low-level beasts are probably enough.

The point is that this one has a lot of meat! Nothing is wasted! ???

On the way back cautiously, they encountered a giant python and died at their hands.

The innocent python because his python skin and snake tendons can be used as ropes.

Poor python, you shouldn't have gone out for a walk today.

The trio found an abandoned cave and began skinning, cramping, and splitting the bones with great skill.

After all, if you are afraid of the smell of blood and welcome a powerful monster, you will lose more than you gain.

After half a day's work, these materials were sorted.

The three of them hid here and there like thieves and returned to Majia Village safely.

Taking out five complete pieces of Daxuan iron cowhide, the iron pillar controlled the magic weapon to begin to remove excess impurities on the skin, making the entire Xuaniron skin uniform and regular in thickness.

Iron Hammer began to use water-avoiding tools, which caused the excess water on the skin to drain away quickly, leaving only the fat.

Picking up the skin and rubbing it back and forth with the Object Control Technique, the black iron cow's skin gradually became soft and wear-resistant.

The python's tendons were pulled out and were very elastic, so they could be used as safety ropes. By using this to tie yourself up, you wouldn't be afraid of falling out in danger.

When the three weapon refiners work together, the efficiency is extremely high.

After all, no one else can help. They can only watch from the sidelines and occasionally hand over gadgets.

When the moon rises above the branches, the entire balloon part of the hot air balloon is sewn.

The hanging basket below was arranged by Zhang San, and was completed long ago through the cooperation of five craftsmen with the best frame making skills. The frame is compact, strong and durable at first glance.

The last thing is the windproof stove. It’s simple, just make it like a windproof torch.

As for fuel, there are no options other than pine oil and vegetable oil, so take some that you can deal with first.

Things were done quickly.

Surrounded by friends watching the fun, the two veterans looked at Musk with a happy look in their eyes and said, "The assembly is complete, what's the next step?"

Musk rolled his eyes and said: "Then take it to the square and try it. It should be able to take off after igniting it."

The crowd cheering and watching the excitement quickly followed to the square.

Fortunately, this area is planned to build a library, but there is no manpower available, so it is still a large open space.

Musk took out the hot air balloon from the storage ring, placed it neatly, and adjusted its position.

Just lit the fire.

Although the fire was not big, the hot air gradually inflated the air bag, and it slowly became more and more round, making it feel like it was about to float!

Seeing this, Musk felt that it was almost done, and quickly asked these little carrot heads: "Which of you dares to go up and try?"

As soon as these words came out, everyone flinched.

Zhao Yun, who was not afraid of either the sky or the earth, hesitated for three breaths before standing up and said, "Master, can I come and do it?"

Musk smiled and said: "What's wrong? What's there to be afraid of? With three immortal cultivators who can fly protecting me, what can happen?"

This statement seems to make sense. These shrinking little boys gritted their teeth, stamped their feet, and crawled into the frame as soon as they closed their eyes.

If you're not afraid, then that's fine. Musk taught Murong Yunhai and Zhao Yun how to control fire. Ma Zhiyuan and Ma Tengfei next to them also listened attentively. Of course, there were also three unnamed carrot heads who also listened attentively.

The operation is also very simple. I told everyone to tie up the safety ropes and then ordered to start increasing the flames to lift off.

The hot air balloon slowly began to rise into the sky. It was as high as a person above the ground, and now it is as high as the treetops, and it is still rising slowly.

The fixed rope tied under the frame is ten feet, but judging from the situation, it should be able to rise to that height soon.

Wu Xiaomei looked at the big boys in the frame with envy, but she wanted to go to the sky to have a look, but she didn't dare to go.

Of course, Ma Yumei and Murong Wan'er could only look up eagerly at the rising hot air balloon and listen to the screams of the children in the frame.

Seeing this situation, Musk took out the stick of virtue and injected spiritual power into it and said to Wu Xiaomei: "Little sister, come up, brother will take you to fly."

"Ah!" Wu Xiaomei was brought back from her envious thoughts by Musk's sudden words.

Seeing Musk smiling, he patted the flying magic weapon he was riding.

"Wow, that seems okay."

After Wu Xiaomei struggled for a while, she decided to walk behind Musk, imitate him and ride on the magic weapon, holding Musk's belt tightly with both hands, for fear of falling off.

Musk used his spiritual power to take off directly into the air, surrounding the hot air balloon to escort them.

Upon seeing this, the two veterans also took out their flying instruments and invited their long-cherished partners to take off together to watch the night view.

The atmosphere has been created here, and the opportunity has been given to you. Whether you can seize it or not is up to you.
