Li Mengxi caught the hen and asked Xiao Brick to conduct a more in-depth observation.

Previously, Xiao Zhuan thought that eggs could be hatched in chicken armpits, and so could humans. He also observed that it might be because of the hair, and he also observed that it might be because of the nest.

It is very valuable that Xiao Zhuan independently observed these things.

However, these are the easiest to observe phenomena.

Going down, more complicated guidance is bound to be required.

Li Mengxi asked Xiao Bian to touch the hen's wings and heels, then touch the ground, then touch the wheat straw nest, and then touch his own armpit. He didn't say anything conclusive, but just let Xiao Bian experience it on his own.

After a while, Li Mengxi asked his brother, "Brother, do you think there is any difference between touching your own armpit and touching a hen?"

"Chickens have feathers, but I don't." Xiao Zhuan answered immediately.

"Well, could it be that chickens have feathers, so the mother chicken can hatch chicks?

Then let’s make chicken feathers and hatch them in the same way, okay?” Li Mengxi asked with a smile.

"Okay!" Xiao Bian replied subconsciously.

Then, Li Mengxi smiled and said nothing. He helped his brother put on the feather clothes again. Halfway through, Xiao Bian stopped.

"Brother, no." Xiao Bian tilted his head and looked at Li Mengxi with a frown.

Although Xiao Zhuan is not very expressive and his logical thinking is not that strong, he realized that chickens can hatch eggs, but humans cannot hatch eggs, and there is no relationship between feathers.

Xiao Bian thought about something clearly, but became even more confused.

Li Mengxi took his brother's little hand and went to the hen again. He let Xiao Brick feel the difference between the hen and the human body again.

"Xiao Bian, is it warmer under your armpits or under the chicken wings?"

"Yes...it's because the wings are warm!" Xiao Bian's eyes lit up.

"Then..." Li Mengxi smiled, "Then what should we do?"

Xiao Bian thought about it for a long time and couldn't figure out what to do next.

At this point, Li Mengxi didn't know what to do next.

The small bricks are too small, so maybe they can't understand what the temperature difference is.

Just when Li Mengxi was thinking about whether he should forget it or whether he should directly reveal the mystery and bring this investigation to a perfect end, "Brother," Xiao Zhuan called Li Mengxi, and Xiao Zhuan acted hesitantly, "Brother.

, is it that my armpits are not warm and cannot be warmed out?"

"Ah, is that so?" Li Mengxi asked with a surprised smile.

That's right. If the body temperature is insufficient and does not reach a certain level, it will not be enough to hatch the eggs.

With a little guidance, Xiao Zhuan understood that people are not as hot as chickens. Chickens are hot, but people are not. People cannot be hotter than chickens, so the chickens will not come out.

Going downstairs, it is Li Mengxi’s task.

"Xiao Bian, tell me, if we find something as warm as the mother chicken, can we hatch the chicks?"

Xiao Bian thought for two seconds, "Yes!" He nodded vigorously.

In order to let Xiao Zhuan fully experience the joy of success, Li Mengxi was very busy.

He hastily made a thermometer. The method of making a thermometer is as follows. He scrapped a top-quality white jade, and asked the craftsman to polish the jade into a long and slender stick, and then drilled a needle in the middle.

Fine holes.

The jade is polished to be thin and fine, translucent inside and out.

After making a thermometer like this, put some ink inside and sew the hole shut.

Boil a pot of water, put the thermometer into the 100-degree water, the water inside expands when heated, and the water column rises to the top position. Mark the mark, which is the 100-degree position.

Then, put it in a cool place and carve a water column position.

Then, put the iron pipe in the hen's wing for a long time. When the temperature inside and outside of the white jade thermometer is completely the same as that of the chicken wing, mark another scale. This scale is significantly higher than the scale of the thermometer in the shade.

Festival.

Then, Li Mengxi found a large number of water bags and began to boil water.

He used a white jade thermometer to measure it. When the water was about the same temperature as a hen's wing, but slightly higher, he quickly filled a bag of hot water and took the hot water to find his brother.

The water bag was handed to the younger brother's hand, "Look at Xiao Bian, is this hot or is it your armpits that are hot?"

Xiao Zhuan carefully touched his armpit and then touched the hot water bag. "This is the hot one!" Xiao Bian pointed at the water bag and said.

Li Mengxi then asked Xiao Zhuan to compare which one was warmer under the wings of a water bag or a hen. Xiao Zhuan touched these two things and stopped answering.

Li Mengxi smiled and asked, "Is it just as hot?"

"Yes!" Xiao Bian nodded vigorously.

From then on, Li Mengxi no longer needed feathers, put eggs in his armpits, or made straw nests.

He built a nest with a hot water bottle and put the eggs in it.

There are many people helping.

Military doctor Tian Bu was responsible for boiling water. Military doctor Tian Bu held a white jade thermometer. He boiled the water for a while and then put the thermometer in to take a look.

As long as the thermometer is slightly higher than the temperature line of the hen's wings, Tian Bu will quickly pour the water away.

At the speed of a wave of three to five minutes, water bags are constantly delivered.

Li Mengxi changed a water bag every once in a while, and another water bag every other time.

"Xiao Bian, do you think we can hatch the chicks now?"

"Yeah!" Xiao Bian nodded vigorously.

"Why can it be hatched?"

"Yes, we use this to drink the stuff in the water. It's just like chicken wings."

It's a mess, but the meaning is completely correct.

One day passed.

In the evening, Li Mengxi and his brother were still changing water bottles with great interest.

After all, the little brick man was so weak that he couldn't bear it and fell asleep.

Li Mengxi couldn't bear it anymore. He was afraid that something would happen if the incubation temperature was interrupted, so he asked military doctors to help change the water overnight.

Generally speaking, in the military today, the craftsmen in the crafts camp are the ones who know best about testing methods, but the ones who know temperature best are the military doctors.

One night passed, and on the second day, Li Mengxi and his brother spent the whole day working on replacing the hot water bottle.

This lasted for three days.

Li Mengxi illuminated the egg with a candle at night and saw the shadow inside the egg.

The seventh day.

Li Mengxi suggested breaking open the egg and taking a look. There was a click, and the egg opened, but unlike usual, there was immediately egg liquid left. Li Mengxi poured the contents of the egg into a bowl.

When Xiao Bian saw the greatly changed appearance of the egg, he saw among the dense velvet red threads in the egg, the white, small one that looked like the prototype of a chicken, but could not see the wings, eyes and other features.

A small, moving chicken embryo.

"Wow!" Xiao Bian shouted excitedly and jumped up.

At this moment, what burst out from Xiao Bian's eyes was the explosive excitement and fanaticism of seeking the truth and hearing it.

"Wow!"

"Wow!" Xiao Bian shouted excitedly.

"Brother, look at it moving, look at it!" Xiao Zhuan was so happy that he asked Li Mengxi to look at it.

Li Mengxi had already seen chicken embryos. He pretended to be extremely surprised, "Wow! It's really moving! Is this a chicken?"

Xiao Zhuan cracked a secret, but discovered more secrets.

Aren't chicks supposed to be fluffy, but why are they so small and so unlikeable?

Can you take out such a small chicken and feed it?

Why do eggs turn into chicks?

Why don't eggs turn into chickens when they are hot? They have to be like chicken wings to turn into chickens?

The egg turned into a chick, where did the egg go?

A large number of questions have been rooted in Xiao Zhuan's heart.

When the entire incubation period was over, five fluffy chicks were hatched from the hot water bottle.

Xiao Brick is undoubtedly extremely happy.

Li Mengxi got him a small box and asked him to put the chicken in it to play with the children.

Little Brick found his friends, and the children gathered around the chicken and squealed in delight.

"This was hatched by me and my brother." Xiao Bian proudly told his friends.
