These eunuchs are still quite fast to help the royal family, but in less than half a month, most of the matters have basically been completed, except for the house.

Zhang Kui also used this half a month to copy down basic technologies such as papermaking and steelmaking.

The next step, of course, is to work hard and work hard to develop. However, even if those immortal sects didn't care about things outside of cultivation, Zhang Kui didn't dare to be too presumptuous, and still proceeded cautiously, only occasionally leaking some things to help improve the living standards of the people within the dynasty.

After a few years, although the impact is not great, on the whole, their Zhang family is in the dynasty, and their Zhang family's status in the hearts of all the people in the dynasty has been slightly improved.

After a long time, Zhang Kui almost forgot that he had to do the task, and he almost forgot that he had to deal with that Zhangqiu. To be honest, if it weren't for the constant flickering of his Heavens and Ten Thousand Worlds Bead quest platform recently, he really didn't remember much about it.

However, this task is useless in urging, they are not at the same level at all, not to mention confrontation with each other, and they can't even make contact.

Although Zhang Qiu is not high in terms of cultivation or status at present, he is also in the cultivation world in the end. But Zhang Kui is still doing his position as the crown prince well, and if Zhang Qiu does not come to their side of the dynasty, he will not be able to contact Zhang Qiu at all.

So, what can he do?

"Are all the things I want ready? ready, all of them will be taken to my dormitory!" At present, Zhang Kui can only forcibly ignore the urging of the task and continue the work at hand.

After completing the basic technology layout, Zhang Kui found that if he really climbed gradually like a normal technology tree, it was estimated that when he inherited the throne, he might not even be able to deal with the Xianmen when he died of old age.

Then, if he doesn't want the mission to fail, he must find a way to cut corners.

So in the end, he decided to start with biotechnology for the time being.

As long as you can make achievements in biotechnology in a short period of time, it is possible to improve the wisdom of all craftsmen, and even make devices that directly instill knowledge through brain waves.

If you can do this, with all the information in place, no more than twenty years should be enough to climb the tech tree to a certain extent.

At that time, I don't dare to say that I can completely defeat Xianmen, but at least I should be able to control a certain number of nuclear weapons as a precaution.

When Zhang Kui came, he had already inspected the specific forces of the Xianmen here, and some Qimen spells and the like were not easy to say, but in terms of overall aggressiveness, the attack power of the fusion nuclear bomb was definitely far beyond the aggressiveness of the ordinary Yuanying Zhenjun here, and if it could make a light bullet, even the Great Venerable of the Transformation God might not be able to hold it.

If it weren't for these circumstances, how could Zhang Kui have climbed the technology tree with confidence.

"Your Highness, everything is ready, do you need our help?"

"No need, don't let anyone in, I'm going to dispense medicine inside!" Zhang Kui closed the door of his palace after refusing, and stayed in the dormitory with peace of mind to configure brain domain expansion potions and genetic modification potions.

The genetic modification potion that Zhang Kui had configured was comparable to poison for a cultivator. Because Zhang Kui's genetic modification potion can differentiate the spiritual root, that is to say, if a qualified cultivator is injected with a genetic modification potion, the spiritual root will collapse instantly, and the cultivation will also get out of control.

Of course, these are for some monks with relatively low cultivation, and if their cultivation is relatively high, even if they are injected with genetic modification drugs, they can still be discharged.

It can be said that after Zhang Kui made this thing, he completely drew a line with the cultivation world.

Feng Yue saw this time, and he could generally understand Zhang Kui's thoughts.

"He wants to replace heaven with humanity!"

An obvious pattern of the Five Elements Small Thousand Worlds is that the Heavenly Dao suppresses everything, and the Heavenly Dao is respected.

And the era of the Son of Heaven enshrined the gods in the ancient legends of the Five Elements Xiaoqian is obvious, it is an era in which humanity suppresses everything and humanity is respected.

Since this small world has had a prosperous era of humanity before, it is far easier for Zhang Kui to restore the prosperity of humanity and suppress the Heavenly Dao than to create a prosperous era of humanity and suppress the Heavenly Dao.

This pattern is far larger than the use of technology to suppress the children of destiny.

Above the court

"Your Majesty, the crown prince is really a masterpiece of the world, and this move is really comparable to the ancient Shennong Emperor!

Since then, I am afraid that there will be no hunger in our court, which is really a supreme merit!" Almost all the ministers of the DPRK and China are singing praises of merit, and this is not only their sycophancy, but they themselves do have such an idea in their hearts.

Think about it, the original rice yield of ordinary people per mu could not support more than 200 catties. Now the Muhe rice researched by the prince can yield more than 1,000 catties per mu, nearly 2,000 catties. If it is really promoted nationwide, it will really be a prosperous era that has never been seen in the ages.

Fitch Emperor was also so smiling that his eyes couldn't see, and when he heard the news, he himself was shocked, and he couldn't believe it was true. But in the end, it turned out to be true.

Zhang Kui is also very happy, as long as all these seeds are promoted, then the plan of replacing the Heavenly Dao with humanity will be the first step, and the most important step will be taken.

Even if he doesn't do anything in the future, the Heavenly Dao will inevitably decay gradually.

What did he do?

All of the seeds are problematic, and all of them have been fortified with some form of genetically modified agents.

The food grown from these seeds is definitely not poisonous to ordinary mortals, mortals who don't cultivate. It even has certain benefits for their bodies, which can make them healthier and live longer.

However, if a mortal with a spiritual root consumes this rice for a long time, the spiritual root will gradually fade or even disappear.

This kind of seed has just been promoted in the first few years, and the situation should not be too serious, and it will only cause a certain degree of decline in the spiritual roots of most people. However, ten years later, if there was no mistake in the plan, Zhang Kui could guarantee that it would be difficult for those immortal sects to find suitable seedlings for cultivating immortals from among mortals.

Even if they can find it, it is only a few, and they may not have eaten this kind of rice since they were children.

But how many years can this last, how many people can have spiritual roots? In the long run, if a sect can't even receive disciples, Zhang Kui still doesn't believe that such a sect can continue for thousands of years.

Killing those immortal cultivators, they wouldn't have thought that the problem would lie with those high-yield grains.
