I, the students, have already thought of using ecology to attack their opponents.

This is something that Lu Chensheng didn't expect, if it weren't for the barbarians that Lu Chensheng was sure to deal with, to be honest, it was to use the trick of destroying the ecology to deal with the enemy, which was actually very good.

Even if this trick continues, the inland will be implicated, but it is much better than being southbound by these barbarians.

Once the ecology is destroyed, the vegetation is completely lost, and the land is not fertile at all.

Naturally, herders are not able to graze, but can only migrate.

When the desert gets bigger and bigger, the other party will have to think twice even if they want to invade the Han country.

Because crossing the desert is not so simple, in case of bad weather, a sandstorm can bury them all.

When the desert spreads around, it is normal for the nomads to die out.

"It's good to have such thoughts, but you have to think more about the consequences in everything, you know?"

Lu Chensheng glanced at the student and said a word of encouragement.

I just taught them about the natural environment and ecology, including what kind of huge harm will be caused if the ecology is destroyed.

At this moment, the other party began to think of using this ecology as a weapon.

Hearing this, the students on the side nodded emphatically.

Even if he was still a little puzzled at this moment, what the gentleman said was absolutely true.

After taking the pen and jotting it down in the small notebook, the student looked up again and continued to ask.

"Sir, you said earlier that species invade this kind of thing, and you said that the world under our feet is very big, and some places are not suitable for breeding other species, because if such species have no natural predators here, then they will be flooded.

Students don't understand, is this invasive species so terrifying? Now the people in Jiangguo, Dacang and Chengzhou are roughly calculated that there are millions of people who can't eat.

If you can put cattle, sheep, or fish in such a unique place, if they can be flooded, then you don't have to worry about food? ”

Lu Chensheng's eyes widened as he listened, and then he looked at his student.

What's going on in this student's head? Lu Chensheng actually felt that it made sense!

Solving the problem of food with invasive species? If this place is occupied, then there will be no problem.

At best, it's just a matter of transportation on the way.

"Sir?"

The student looked at Lu Chensheng from the side and called out cautiously, afraid that his idea would be aborted again.

At first, he thought of destroying the ecology to exterminate the nomads, and he thought it was very useful, but his husband refused to let him, saying that it was a huge harm.

Nowadays, I don't know if Mr. can approve of using this method to control the desire to get abundant food.

Lu Chensheng glanced at his student, and then nodded, "There is no place for you to experiment right now, but if there is a new place in the future, how about Mr. let you try it?" ”

Lu Chensheng touched the other party's head and felt that this kid was a bit of a ghost.

When the student heard this, his face was full of surprise, and he nodded again and again with great excitement.

Lu Chensheng shook his head, if the invasion of species is not curbed, it will also become the destruction of the ecological balance.

For example, if rabbits in a place have no natural predators, the hares in this place can be flooded, and then they will continue to eat away at the vegetation, resulting in the end all the vegetation will be eaten, and then the hare will naturally be extinct.

But Lu Chensheng thinks that if you interfere with one or two as an artificial person, periodically hunt and kill and then bring it to the table, it is right to maintain the ecological balance.

If this move is successful, then farming will be much easier in the future.

However, this idea is a little too old, and I am afraid that such a place can only be found after going to sea.

After asking a few more questions, the students on the side bowed respectfully and turned to leave.

"What do you mean by that?"

Bai Yi had already come to the side just now, and when he heard what Lu Chensheng and his students were talking about, he was stunned, and he didn't know what they were talking about.

The rest of the students on the side listened with relish and took notes.

At this moment, Bai Yihu felt that what he had learned was not as good as these students.

"It's just about nature, earthquakes, tsunamis, volcanoes, and ecological circularities."

Nature and the like are actually a course that these students are quite interested in, and the other is astronomy.

It's just that Lu Chensheng doesn't know much about astronomy, so he can only pick out some things he knows and tell them to his students, as if they were extracurricular knowledge.

Bai Yi was stunned for a moment when he listened, "Just now that student said that if you let those nomads herd a large number of sheep and eat the turf, they will let themselves be extinct, is this true?" ”

Bai Yi is more concerned about this problem.

She also fought with these barbarians, and when she was in Chengzhou, she often had these guys who came to plunder.

Every year, a lot of men and women are arrested, and then they are arrested for all kinds of bullying and humiliation.

Thinking of this, Bai Yi naturally had hatred in his phoenix eyes.

"Naturally, it is possible, if you are helping to eliminate the natural enemies on the grassland and let the sheep flood, the progress will be improved a lot, but it is not in our interest to do so, and this grassland will still be ours in the future."

Lu Chensheng looked at Bai Yi on the side, and then spoke.

When Bai Yi heard this, he looked at the heavy cavalry who were still training on the side, and they were covered in black armor, which made people daunting at a glance.

This armor is really a fine product in terms of defense, and the blades she held in the past are like defective products.

Originally, she heard that there was such a way to easily eliminate foreign enemies, but she was still extremely excited, but her father-in-law didn't seem to want to do this.

"The armor forged by Xiang Gong, although it is extremely hard and invincible, still needs to be piled up with mountains and seas of blood to be able to knock down this grassland, and then drive away these barbarians."

It's right that Ci is not in charge of the soldiers, but in the end they are all their own soldiers, if they can, Bai Yi also thinks that his soldiers will follow him, and Rong Ma will be able to go home with peace of mind after his life, and accompany his parents.

"Why do you make the lady think that this is the husband's most powerful method?"

Lu Chensheng was stunned when he heard this, and then looked at his wife and asked with a smile.
