Chapter 683:

Li Huai now wears a coat, pants and a rabbit fur coat in winter, equipped with bone buttons he carved from the skeleton of a moon hound. He started to get fat, but he also realized the paleness of his skin. He wanted to know whether spending enough years in this sunless world would make him pale and transparent like a moon hound.
But for a long time, Li Huai has not forgotten his ultimate mission-to reach the ground and send out a distress signal. He solved the problem himself. He had to make some kind of space suit, which allowed him to venture long enough on surfaces with little air to establish a signal that astronomers might see.
He knew that the metal he rescued from the nose of the rocket contained some of the materials for this suit. He can polish a section of enough to make a helicopter helicopter, and the helicopter can flash code information to any high-power telescope that may point to him. But he must also make metal into a sealed space helmet, and he doesn't know how to do it. He may be able to make a suit from clothes and tanned skin, sew it and seal it short enough with animal fat and bone glue to make it airtight, but he needs a helmet. He also has a glass, a small peephole at the exit of the camera, and a large circular plate at the bottom of the cargo nose, which is obviously used to photograph a large area of ​​the earth. This plate is his face plate.
Li Huai knew the hiss he first noticed when he arrived, but he never investigated it. It is far away, somewhere along the cave wall. During a working period, when he found that he was ahead of schedule, he set out to search for noise sources.
Immediately following the wall, in front of him, the hiss gradually increased. Li Huai bypassed a sharp crack and pierced a large bubble hole in the wall. After walking for about two miles, he came to the source.
The rupture of the cave wall gave off a blue flame. In the hundreds of feet around it, no vegetation grew, and the ground was covered with thin ashes. Li Bai looked at the blue spear hissing loudly.
This may be a breakthrough between adjacent bubbles, which are filled with some kind of flammable gas. During the breakthrough, this leak was ignited. Now there, the burning jet is sharp and hot.
At that moment, Li Huai knew that he could solve his metal processing problem. He tried to melt the metal of the rocket on the fire, but he completely failed. But this jet, this hot blue flame will surely succeed!
For him, the space helmet is now certain. This may take some time, but it can be done now. There are more possibilities, because he has enough metal to make some necessities, such as a decent frying pan and a pot for boiling, or maybe a water container for a long exploration trip.
That was the end of Li Huai's first "Stone Age" and the beginning of his "Iron Age".
Incredible footprint
It turns out that using a gas nozzle is much more difficult than originally thought. It's hard to get too close to things without risking your head. In addition, in order to keep the metal long enough to melt or become flexible, it is necessary to find a way to keep the object from burning.
Li Huai did cause several blisters before finally working out a system. Pairing thick rabbit leather gloves lined with a thin layer of ashes in the area surrounding the flame proved to be part of the solution. It turns out that the necessity of replacing pliers is continuous, and using pliers is another part.
Then working patiently, Li Bai managed to cut and machine some metal plates from the rocket nose. He struck it with a hard stone hammer, breaking it into pieces, and finally shaped himself a useful, albeit crude, frying pan and other tools needed.
His next project is to become a space helmet, which is the first element of all space suits. He thought about it for a long time and planned how to do this. His work is suitable for using a good metal plate, but he does not want to make any mistakes in the process, and he wants as few seams as possible. So far, welding has proved a task he has not yet mastered. He considered making the joints airtight through some kind of vegetable or animal fat products.
After a month and a half of winter and thinking, Li Huai sat in his cave watching the rebirth of the bubble world. He watched his monkey Chiki dig through the stones to find moon worms-although the little brown pet had never eaten them, he seemed to like to hunt these strange creatures. He looked at the rabbits in a circle and listened to the rabbits he kept in the next cave.
"What am I waiting for?" he asked himself aloud. The monkey stopped when he heard his voice and looked at him. Li Huai developed the habit of talking to himself. He realized that the hermit's many years of life might lead him to the danger of forgetting to speak, and he didn't want that. "Until I found a way to the ground, I couldn't use a spacesuit-a safe method. And I never even really explored the cave itself. Maybe there is an easy way to communicate with the ground."
He sat down and thought. The monkey rushed towards him, jumped on his knees, shaking. "I should really explore this place," Li Huai continued. "You know, cheeky, we have more things to use. What do you say, should we play in Columbus next week to find more bubble worlds to conquer?"
The monkey trembling happily, jumped off his knees, and ran around. "Guess you like this idea," Li Hao said. "So, let's get started."
He got up and prepared. He packed enough food in sack for a few days. He picked up a self-made canteen made from hollowed out moon tree peel, filled it with water, and hung it around his neck. He is holding a flashlight and a knife, a bow and arrow and a light organ lantern. He found that the light bulb that emits a small light when the animal is taken away will glow after about two days, so he keeps filling the lantern with newly caught things.
He checked his special rabbit to see if there was enough food and water during this period, then whistled towards the cheeky, Li Huai set off. He walked to the shore of the stream that had been taken away, and then proceeded to walk along the length of the stream into the distance of the bubble world.
He followed the current for about twelve miles. The air bubbles expanded, and the water on the other side of the cave that had been brushed by Li was now narrow, because a pile of dry ground had formed on the other side. Li Bai found himself walking through the deepening bushes of the growing moon tree.
The stream twists and moves at right angles, and finally rushes into the deep pool. Li Badi walked over and stared at it. Obviously, the swimming pool has some kind of underground opening because the water is spinning and there is no visible water outlet around it. So this is where the stream flows! There is no doubt that it poured into another bubble somewhere below, and it might have fallen into that space like a waterfall, where it became another stream, and again became empty farther, until it was on the moon. End in the vast reservoir below.
But Li Huai was not interested in going further, he tried a way to move up to the ground, towards the earth's line of sight. He turned from the whirlpool and walked to the farther wall of his bubble house in a limited way.
