A few white people didn't do it immediately, because Yang Zhou's bodyguards were watching everyone behind him, and finally Tok Andy in the middle shook hands with Yang Zhou enthusiastically.

Enthusiastically: "Professor Yang, thank you so much, if it weren't for you, we might not have lived to 2022!" ”

The other two also thanked Yang Zhou, and Yang Zhou naturally wanted to be polite, but he still cared about iron grass.

After a few small talks, he asked, "Andy, where did you find the iron grass?" ”

"Oh, since I heard that Professor Yang is looking for iron grass, I have been contacting everywhere, and finally I heard that this iron grass was discovered by a scientist in the Amazon forest of Brazil, and he wrote a paper that the local primitive tribe actually used this iron grass to make iron tools." Toc's Andy explained.

"Amazon! The lungs of the earth do have many amazing plants, and scientists discover new species every day. Yang Zhou nodded.

The Amazon rainforest is an amazing place, home to one-fifth of the world's freshwater resources, supplying one-third of the planet's oxygen, and 60% of the area is in Brazil, although the forest area is shrinking every year.

The trees surrounded by more than a dozen people are being cut down every day, and the locals burn the forest to plant.

Yang Zhou wants to pull scientists from all over the world to study the genetic map, also because there are many amazing plants abroad, especially the Amazon rainforest.

Iron grass is planted in flower pots, and some are sick, but Yang Zhou carefully observed and found that it was the same as the pictures circulating on the Internet, but whether it was iron grass or not, it was still necessary to check the element content in the iron grass, whether it was rich in iron.

And even what the difference is between genes.

If it can make iron, it means that the iron grass must be able to absorb the iron element, otherwise the iron element cannot be produced out of thin air.

Yang Zhou is going to talk to these people about the price, giving a preferential price for cancer treatment or something.

Several other people also said: "Professor Yang, we also brought some special seeds, and also bought some plant gene maps, do you want to take a look?" ”

Yang Zhou is naturally interested, and he is very interested in the genes of any characteristic plant.

Since obtaining the system, Yang Zhou has studied countless plant seeds and plant genes, forming a set of basic theories, and now the textbooks he compiled have been handed over to the printing house of Qingbei University for printing, and will soon appear in the hands of students, Yang Zhou has to find time to take public classes at the university every month.

"Where?" Yang Zhou asked with interest.

"The seed is here, the data is in the USB flash drive, and there is a computer here, I'll open it for you to see." Said the young white man.

Yang Zhou was about to go back and see again, but when he heard the patients say this, he nodded.

The young man finished speaking and was about to go into the house to get his laptop, while the old man also stood up and seemed to be looking for something in his pocket.

After a while, the young man took out an Apple computer from the room and had a USB flash drive in his hand, but this USB flash drive was more unique and looked quite long.

There are all kinds of USB flash drives in recent years, and Yang Zhou didn't suspect anything.

He was not very wary of these patients, and felt that they were all rich people, who had traveled thousands of miles to China for treatment, and brought him gifts, and even had some good feelings in his heart.

Although Wang Qiang and the others behind him were vigilant, they didn't feel any threat from a few sick seedlings.

The room was also carefully inspected before and no danger was found.

Seeing the USB flash drive plugged into the laptop, Wang Qiang had some doubts in his heart.

He frowned slightly, wondering what was wrong.

When the white young man approached Yang Zhou with the computer, it seemed that he was preparing for a live demonstration, and the white old man's hand was also taken out of his pocket.

There were countless strange seeds in his hand, and Yang Zhou was also a little puzzled, why did this person put the seeds so casually and put them directly in his pocket?

Just as he was looking at the seeds, Tok Andy's hand that was originally stroking the leaves suddenly forced, pulled up the iron grass, and quickly took out a pistol made of special materials from the flower pot, which was not metal, but parts made of special materials, and was sent to Red Beach by Tok Andy and his people in batches to assemble the weapons that had only been assembled.

Even when it was buried in the soil this morning, the security personnel checked it before, and they didn't even think about digging up the soil.

It can be said that it is a security blind spot.

Tok's Andy roared angrily, "Do it! ”

The white young man on the left flicked the laptop, and the USB flash drive suddenly turned into a knife, with the distance between him and Yang Zhou, plus Yang Zhou's gaze at the seed in the old man's hand, he could almost fatally insert the knife into Yang Zhou's neck or chest with one blow.

Tok Andy also quickly held the pistol and aimed it at Yang Zhou, ready to snap a few shots.

Although he may soon be shot to death by Yang Zhou's bodyguards, everything doesn't matter, their purpose is to find Yang Zhou to die together.

Everything happened in just 1 second, and even Wang Qiang and the others were in a hurry at this time.

After strict training, they are also ready to draw their guns immediately, at this time, they can not care about anything else, and they are ready to kill these people directly, but don't let Yang Zhou get hurt.

But their reaction was actually a little slower.

Yang Zhou is a person who is very afraid of death, and almost when something happens, he knows that he has encountered a killer.

And Yang Zhou is a very cautious person, he has prevented the pharmaceutical group or the food group from attacking him before, and specially transformed the small revolver.

It's just that a few days ago, I studied the genes of advanced plants, and melted the small revolver transformed by the fire plant.

In this case, Yang Zhou certainly felt a little less secure.

In the mysterious space, some self-defense means were made.

When encountering danger, throwing things from space and smashing people is definitely not good, this is too mysterious.

Yang Zhou used other means!

That's the smell of the soothing tree.

The space is accelerated by 128 times, and it is only 3 days in 1 year, and it has been a long time since the Tranquility Tree was obtained, and there is already a mature Tranquility Tree in Yang Zhou's space.

It exudes a special fragrance every day, and although Yang Zhou has not done in-depth research, he also knows several of its characteristics.

The fragrance is colorless and spreads extremely quickly!

Imagine a tranquilizing tree that can quickly infect a 10-kilometer range at night, and the speed will definitely be very fast.

Whether it is an aroma or a smell, when it spreads, it is caused by the rapid movement of molecules.

When it encounters the human body, it will immediately infect the central nervous system of the human body, transmitting the signal of sleep, which is not affected by willpower at all, and makes all human beings fall into a state of stupor.

Moreover, the nerves are cut off, and Yang Zhou currently does not know other means of arousal.

The fragrance molecule is very magical, only cutting off the sensory nerves, such as breathing blood, etc., are not affected, but after infection, people will lose consciousness and fall into a coma.

Of course, the soothing tree releases its aroma at night, and during the day it releases another colorless and odorless gas, just like the oxygen in our air.

This colorless and odorless gas is generally emitted in the early morning and will wake up people who are dazzled by the aroma of the soothing tree.

Yang Zhou can control his own space, and has stored a part of the aroma in a specific air wall early, and after he falls into a coma, his consciousness actually enters the system interface, and he can also release the wake-up gas.

This is Yang Zhou's strongest self-protection method at present, I thought that I would never have a chance to use it in my life, but I didn't expect it to be used not long after.

At this time, with Yang Zhou as the center of the circle, within a radius of several kilometers, the aroma of the Anshen tree spread rapidly, and everyone did not have any power to resist, and they all fell to the ground.

Everyone who was close to Yang Zhou fell to the ground within a few tenths of a second.

Before Tok's Andy pistol could be raised, the man fell.

Wang Qiang and other bodyguards and Obrera also didn't say anything, and they also fell to the ground in a coma.

The entire cancer hospital fell into a strange and terrifying atmosphere, and no one standed!

When Yang Zhou fell to the ground, a spray bottle fell out of his pocket, but no one paid attention to it.
