With Tang Yue joining the laboratory, the speed accelerated again, and every time Yang Zhou did not need to remind him, Tang Yue could prepare in advance, and Yang Zhou only needed to use a special syringe to inject one Cas9 gene editor after another into the hybrid rice germ seeds.

Moreover, Yang Zhou found that he could sense the internal changes of the seeds during injection, which may also be the reason why he used the common technique and the success rate was still very high.

So this work can only be done by himself.

At the same time, the greenhouses in Qiankou Village also began to be renovated.

Now we are growing rice, and we need to change the dry land to paddy fields, but of course there is no need to change some of them, because some of the mutated rice has been transformed into upland rice that can be grown on dry land, but the yield is much lower than that of paddy fields.

A small part of the mutant rice can still survive in saline-alkali land.

There are many mountainous areas in the land of Huaguo, and some places can be transformed into terraced fields, but there are many places that are not suitable for transforming paddy fields at all.

Because of the geographical environment, there is a shortage of water in the north, and most of the crops are wheat, and they mainly eat various pasta, rather than rice.

If upland rice yields more than wheat, many farmers in the north are expected to grow upland rice and wheat together in the future.

The experiment was carried out in an orderly manner, Yang Zhou and Tang Yue met again, and there was no bloody incident, both of them maintained restraint, but Yang Zhou's food was taken over by Tang Yue again, which was much better than when he was alone.

To Yang Zhou's surprise, his system could finally be upgraded again.

Recently, the media has been reporting on his news, which has led to a huge increase in popularity, and the number of followers on Weibo has exceeded 4 million.

Occasionally posted on his station B account, everyone saw that Yang Zhou often worked overtime until two or three o'clock in the morning, and came to the laboratory early the next morning.

In order to let everyone know what Yang Zhou is doing, CCTV specially invited experts to make a popular science video.

Roughly explain the land composition of our country, the food crisis, the greatness of Yuan Lao, the rise of hybrid rice, the birth of "giant rice" and other topics.

Countless people know that there was a food war between China and abroad, and the food war evolved into a soybean futures financial war, until now, China has kept rice, wheat and other crops, and the staple food is basically self-sufficient, but in soybeans, it is still completely dependent on imports, and even seeds are controlled by foreign countries.

Many young people didn't know much about all this, but now they are beginning to understand it.

The topic of Yang Zhou's research is to increase the yield of "giant rice" again, taste better, and adapt to more environments.

Many people left messages in the comment area, hoping that Yang Zhou could succeed.

Everyone didn't have much hope, Yuan Lao and countless biological scientists took decades to optimize the existing hybrid rice, how could Yang Zhou optimize the hybrid rice again in a few months.

Leaving a message in the comment area to bless Yang Zhou is just a good wish.

At the same time, Yang Zhou is only 24 years old and will become a professor at a top university, and he has more resources for hybrid rice research.

After Yang Zhou's experiment was done that day, he went back to the hotel with Tang Yue, and when he arrived at his room, he was looking through these comments.

"Come on, Yang Zhou! Although I don't believe that you can succeed quickly, but with the mutant carrot in front, I believe that it will take more than ten years to transform the rice and increase the yield of hybrid rice again! ”

"It's so hard, I watched Bingbing post videos for several days in a row, and they all worked overtime until two o'clock in the morning, in fact, you don't have to be in such a hurry, Yang Zhou, you are still so young, you have to take care of your body!"

"Yes, Yang Zhou is too thin, and it is rumored on the Internet that Yang Zhou is sick, I don't know if it's true."

There are all kinds of comments in the comment area, and on station B, the comments of the top few likes are all comments that care about Yang Zhou.

A few sunspots leave messages, and it takes a long time to see them.

Yang Zhou entered the system and checked the experience value data, which originally cost 100,000 experience points to upgrade the system to LV2 level, and there was not much experience left.

But now, the experience points have skyrocketed to 1.13 million!

This is probably the experience value of all the people on the whole network who really pay attention to Yang Zhou, hope that Yang Zhou will make achievements, and look forward to Yang Zhou's good health.

With so many experience points, Yang Zhou no longer hesitated and immediately chose to upgrade the system.

Anyway, what restricts Yang Zhou's upgrade now is only experience points, and he doesn't lack money at all.

"System, upgrade level 3!" Yang Zhou thought silently in his heart.

[The upgrade system will deduct 1 million RMB, 1 million experience points, yes/no upgrade?] 】

"Yes!"

[Please donate 1 million RMB within 15 days, and the relevant funds will be frozen.] 】

[The host has been detected to have donated 11.35 million, and the donation amount has been deducted by 1 million, and the current donation amount is 10.35 million.] 】

To Yang Zhou's surprise, there was no need to donate again this time.

The system has counted the donation money earned by Lu Yuyao from selling carrots into the donation amount.

The system upgrade level 4 requires 10 million funds and 10 million experience points, and the donation amount is completely sufficient, but the experience point gap is relatively large.

opened the mailbox and looked at it, and sure enough, Lu Yuyao reported her work a few days ago, and she had donated the money to the charity foundation established by Han Hong, with a total of 11.35 million, which was the money earned by selling radishes at a low price in the early stage and sponsoring Shunfeng.

The email also specifically stated that it is expected to earn several million yuan by the end of August, and it will be donated again when the time comes, and all donations are in the name of Oasis Ecological Biotechnology Co., Ltd., because this can be a tax deduction for Yang Zhou's technology company.

For example, this time, Yang Zhou sold technology and earned 200 million yuan from selling seeds.

When calculating taxes at the end of the year, these are considered net income and are subject to taxes.

However, with proof of donation, taxes can be fully offset with the donation (previously it could not be fully offset, later the new regulations).

The corporate tax rate is a very complex matter, all kinds of value-added tax, urban construction tax, education surcharge, real estate tax, vehicle and vessel tax, and most of the enterprise income tax is 25%, of course, the state-supported high-tech enterprises are generally only 15%, and it is possible to get a variety of preferential tax reduction policies.

Fortunately, Yang Zhou invited Zhong Hong to be the chief accountant early, so he basically didn't have to worry about these things.

And, soon, he will have to donate all his money, and the company will not make a profit at all.

Of course, Yang Zhou wants to donate 10 million to level 4 and 100 million funds to level 5, and not to a charitable foundation like the Cross Society, whose funds are not very transparent, but is ready to learn from Ahri to make an ant forest, which is used for afforestation or the construction of primary school buildings.

After the system was successfully upgraded, Yang Zhou immediately entered the system, ready to see if there were any new features, or if there were any changes in the mall.

Yang Zhou had harvested a stubble of mutated radishes before, but then the land was idle, because the speed was too fast, he didn't dare to plant radishes anymore.

It takes more than ten days to harvest a stubble, and there are as many as tens of thousands of giant turnips, so I don't dare to sell them casually.

He also wants to grow some Chinese herbs, such as ginseng, Polygonum multiflorum, Ganoderma lucidum, and other high-value slow-growing things.

Many medicinal herbs do not need to be sold for money, and they are life-saving treasures.

The system has reached level 3, the space is accelerated by 16 times, and the plants that mature in a year now only need about 23 days, and in a few months, he can mass-produce ginseng and Polygonum multiflori.

It's just that Yang Zhou has never figured out one thing, the mysterious space is completely contrary to the laws of nature, and planting consumes so many nutrients, but he has never been reminded to supplement his nutrition.

"Hey, there's a new feature!" Yang Zhou muttered in surprise.
