There are a lot of threads in the robot arm, and Xia Qingzhu is very skilled in pulling out the few that he needs.

Yun Fei searched his memories and found that neither the original body nor the original body's younger siblings could do this.

I don't know if it's because they're all scumbags......

Or is Qingzhu too smart?

Even though he didn't go to school, he was able to skillfully disassemble these bits and pieces of machines, and if necessary, install them back.

Yun Fei just wanted to walk away, when he suddenly felt a very hot temperature in the house.

And the source is exactly what Xia Qingzhu is fiddling with.

searched for the memory of the original body, and it was very good, it was really worthy of being a scumbag, he couldn't recognize it......

So Yunfei had no choice but to humbly ask for advice: "Son, what is this?" ”

"Thermal energy, you can put one in the house when it's cold, this one will be used up quickly.

Generally, this kind of thing will have a loss rate, so I can stimulate it to make full use of the energy consumed. ”

I saw that he opened the black box with his hands and feet, and then took a tool, and after a few strokes, he took a few from the box containing small parts and put them back in.

I don't know why, I feel inexplicable......

I remember that when the air in the dump was cold, the temperature inside the hut was indeed warm.

Yunfei was embarrassed to ask for it, "Son, can you give this to Dad?" ”

He's still wondering where the refining fire comes from, isn't it?

"Yes!" Xia Qingzhu agreed happily, and didn't even ask what he was doing with it.

This thing is still very easy to pick up, and people who don't excite the loss of energy will have to throw it out after taking it home for a day or two.

According to Yunfei's understanding, just like the batteries that were used in the past, after their practicality is exhausted, there is still some electricity, but they are not used.

The original battery, how many people use it, bite it, and can use it for a while, this is the lost power.

…………

Yunfei took the black box and walked to the other side with a complicated mood, not disturbing the child's hard work.

It's not a scarce thing, but don't forget, it's a garbage star with scarce supplies.........

If you exchange it for nutrient solution, you can exchange it for a day's rations for both father and son.

Speaking of rations, Yun Fei remembered again and continued to stuff the tube of water to Xia Qingzhu.

And said: "If you don't drink it, then I won't drink it either, and the two of us will starve to death and die of thirst." ”

Hearing this, Xia Qingzhu took a sip of the water-

Looking at that tube suspiciously, why is it still more bitter than yesterday? Is it broken for too long?

"Okay, I'll drink, don't disturb my work, don't worry, you won't starve, tomorrow will be the day to take out the garbage."

"Hmm-"

Yun Fei refused in his heart, no, he didn't want to drink the stinky water-like nutrient solution!

You have to make money quickly.........

He took the black box to the side, then took a few ores from the iron bucket and put them in a pot of special materials that he had picked up.

This is a pot for interstellar experiments, which is very sturdy and very heated.

It should be thrown away because there are too many impurities accumulated at the bottom of the pot and it can't be cleaned up.

Yunfei opened the black box of thermal energy, then poured a tube of water into it, took out an iron block from the bucket and put it in to burn.

Xia Qingzhu, who had paid attention throughout the whole process, was not interested when he saw this.

If the impurities at the bottom of that pot are not cleaned up, no matter what you do, they will stick to them, and you can't use them at all, otherwise others won't lose them.

Like his father, who didn't even clean it, it is conceivable that the final result is just an extra piece of scrap stuck together at the bottom of the pot.........

An hour later, however, he was shocked!

"Dad, how did you do that?"

I saw Yun Fei carrying the handle of the experimental pot and pouring a bunch of black things into the trash can.

The pot, which was originally uneven and full of discarded materials, has become smooth and smooth, and although it is still a little worn, the inside is completely clean!

Xia Qingzhu couldn't figure it out, Brother Iris had a lot of hard work to find a relatively clean test pot in the garbage dump, which can be cherished in ordinary times.

It is because the bond accumulated by this multiple substance over time cannot be cleaned up, so it can only be thrown away and replaced.

Now that he actually saw his father, he simply cleaned it up, how could he not be shocked?

Yun Fei didn't hide his secrets, pointing to a black stone and said, "After this stone is cooked, it can flow out an acidic substance.

So boil it with water and let it sit for a while to fully corrode away those impurities.

However, it is necessary to pay attention to this time, if it is long, it will also hurt the test pot, but the probability is not large, after all, the test pot is a good material. ”

"It's as simple as that?"

"Well, how complicated can it be?" Yun Fei asked with a smile.

Xia Qingzhu felt that he had reacquainted himself with his father, it turned out that he was really biased......

The mind is used in all kinds of knowledge, this is grandma's evaluation of Dad.

And the evaluation of the uncle is: empty brute force, no brains.

There is also an evaluation of my aunt: cowardly as a mouse, unusable.........

The three children are: one is smart, one is stupid and bold, and the other is a coward.

The tuba is all wasted, fortunately there is his eldest grandson, who is very young, otherwise grandma is afraid that after she and grandpa die, the three brothers and sisters of my father will starve to death.

Alas, grandma and grandpa also said that they would work hard to save money for him to get into a federal university......

Unexpectedly, neither of them had a chance to see him grow up, and they didn't know if his uncle and aunt were still alive.

………

After Yunfei cleared out the test cauldron, he began to refine things.

The large ones are not good for the time being, he thought about it, and still started with the dagger he picked up.

The material is very ordinary, and it can be processed with this thermal box.

He didn't intend to melt it down and refine it again, but he planned to sharpen a suitable dagger tip and then coat it with a layer of hard, sharp material.

Finally, engrave a few more small formations and bless them.........

I can't finish it for a while, and I can't give up my daily meditation at night.

Force value is fundamental!

After Xia Qingzhu fell asleep, Yun Fei got up and sat cross-legged, practicing the spirit induction decision in a loop.

He didn't prepare how high his cultivation could be, as long as the aura was enough for him to refine the weapon.

After all, the aura of this world is also poisonous!

After introducing the spirit into the body, it is necessary to purify the spiritual energy first, and then travel through the meridians to absorb it.

If it's a single spirit root, it's fine, but if it's a five-spirit root, I'm afraid it's hopeless to build a foundation in this life.

Suddenly remembering something, Yun Fei took out a few spirit stones from the space and placed them in the corners of the iron house.

Put the array of eyes, and the fingertips struggled to condense a trace of aura to activate-

Why didn't he think of it before, a small formation to nourish the body, people stay in the house for a long time, the body can be nourished by aura, so as to prolong life.

I overslept, tomorrow five watches
