Children's growth is almost negligible every day. All changes happen unconsciously.

After the sons got up from their nap, Lanze took them to change the sheets. The sheets + pillowcases were thrown into the washing machine, and then he let the sons wash clothes and play. A baby, a small basin, a piece of underwear and half a basin of water.

You can play all afternoon. Even half a year ago, they couldn't play this. At that time, they didn't have enough concentration.

Among the four children now, only Xiaomai’s attention time is slightly shorter. But since Lanze doesn’t need to keep an eye on the four children at the same time, it’s not a big burden to look at Xiaomai more. He just needs to find a way to give him more time to do laundry.

Just find a few exciting points. Washing with water is not fun, so you can add laundry detergent. The hypoallergenic version of neutral laundry detergent will be fine after a few sips, and it still smells delicious.

The most common illusion in the world is that life seems to have no end day after day.

This day passed peacefully as usual. The next day was Army Day.

After all, the school belongs to the army, and there were grand celebrations. Zhang He put on his uniform early in the morning and drove out. As soon as he left, it was another day. He didn't enter the house until the evening.

It wasn't until she reappeared at home through the small garage door that Lanze had the opportunity to talk to her and ask her if she had eaten well at noon.

He is a grown man, and he cares most about eating and sleeping all day long with his children. He is nagging about his mother-in-law and mother-in-law.

"My summer vacation ended early." Zhang He was in good spirits. "In addition to participating in the selection of this year's new students, I also have a short training class to prepare."

"What is the short training course for?"

"In the first period, I am considering strengthening the auxiliary teaching staff in the school. First, ensure the teaching standards." Zhang He replied.

Under her calm appearance, Lan Ze seemed to feel a little excited.

"Okay, I'm going to change clothes first." Zhang He turned to leave.

"Wait a minute!" Lan Ze noticed that her epaulette seemed to have changed. "Where did the plum blossoms on your shoulders come from?"

"Well... there was a ceremony for the title conferment today. However, this is what we originally agreed with them." Zhang He turned his head and looked at his shoulder.

On her epaulette, there is now a five-petal plum blossom.

So, is General Zhang the real General Zhang now? The rank of major general is not a temporary rank like brigadier general. Although she only has plum blossoms, not stars, she is a civilian.

But major general and brigadier general have completely different meanings.

The major general is a formal role with authority in the regular military sequence.

So, before that, the brigadier general's whiteboard had been hanging up for her for a month and a half. What was the purpose of this?

Lan Ze thought so and asked the question.

"Why doesn't the school just give you your current military rank?"

"I've never been a soldier." Zhang He said, "You have to learn the rules and disciplines for a while, right? Besides, I won't be expelled if I leave the alliance! Keeping a low profile will do no harm to everyone. But..."

She suddenly felt a little embarrassed, "I don't know if people have become more sensitive after pregnancy. In fact, I was also worried about whether I would just be idle. Especially, I got pregnant as soon as I joined the job. This is not a suitable state for work.

.”

"Aren't you worried now?" Lan Ze asked with a smile.

"I'll try my best to arrange my own rhythm." Zhang He was really excited, "You know what? I personally select talents and personally train targeted talents. This is the ideal of every captain! It's simply

A dream come true.”

"Is it that exaggerated?" Lan Ze could understand her thinking, but he couldn't believe how happy she was.

"You don't know, on the Jiahe, no one uses that uncomfortable force."

"Aren't there tens of thousands of people on the ship?"

"There are only so many useful people. You leave everything in their hands, but you are afraid that they will be tired. If you don't let them do it, let others do it for you, and you have to be prepared to clean up the mess. In short, it's quite good

It's annoying." Zhang He shook his head and couldn't help but smile and said, "At that time, I was trying to find ways to train manpower on the ship. But how can there be a school that is satisfying?"

Lan Ze watched Zhang He jump into the elevator. This girl is walking like a breeze now.

After Zhang He ended his summer vacation early and started working, Lanze's experiments were slowly carried out one issue after another.

The experimental results were no different from those in the first phase. The main result was that it was proven time and time again that his cells were more viable than others. Later, he simply scraped some of his own oral epithelial cells and put them in a small dish.

, soak in light salt water, one part covered and one part uncovered.

These cells lived up to expectations and died very quickly...especially the ones that were not capped. When the light salt water dried and turned into salt frost, the cells died. For the capped ones, although the salt water did not dry out, the cells quickly became in the air.

Food for mixed microorganisms.

However, these oral epithelial cells also live a little longer than ordinary people. This is according to the existing literature data.

Then he took some of his own oral epithelial cells and made microscopic mounts. He specially sealed the light salt water with tape to prevent the water from evaporating and microorganisms naturally couldn't get in. He just wanted to see how long this thing could stay alive.

He really figured out the mystery of having only a son but not a daughter only two weeks after Zhang He went to work.

Lanze finally studied micro tadpoles carrying X chromosomes and micro tadpoles carrying Y chromosomes separately. Generally speaking, tadpoles carrying Y are relatively slender and swim fast; tadpoles carrying X are relatively thick and round and have good endurance.

A large number of tadpoles released by a normal man at one time can achieve a certain balance in the competition between speed and endurance. Near the ultimate goal, when Y's energy is exhausted and unable to swim, X can catch up. So, under normal circumstances,

The sex ratio of offspring is nearly balanced between men and women.

Lanze's Y tadpoles are also slender and swim faster; his X tadpoles are also thicker and rounder and have better endurance.

The only problem is that his tadpole endurance is actually quite good.

Among the samples stored for more than five days and the rehydrated dry samples for more than a week, Y tadpoles only showed tiredness from swimming, and X tadpoles showed their endurance advantages only at this time.

During this rally time, boys have already taken root in the uterus. To be precise, this long time is enough for the Y champion of the running competition to fuse with the target egg, and then divide into hundreds of cells to become a blastocyst, and the blastocyst is leisurely

Travel to an open and warm land, choose the most comfortable Feng Shui land, and then successfully settle down.

Based on this, it would be really difficult for him to have a daughter.
