Archduke Ganya glanced at them and said in a deep voice, " "Alright, let's go back to the camp." "Sir, let's go back to the campsite and have a good rest. It won't be too late for us to observe carefully after that," he said to Zhao Hai. Zhao Hai did not object. He only nodded. Then, Grand Duke Ganya led Zhao Hai forward. Ganya's son and his subordinate only glanced at Zhao Hai curiously before following Grand Duke Ganya.

After a while, they arrived at a campsite. The campsite was very large, and there were about 10000 people in the campsite. Moreover, these 10000 people were all professionals, from botanists to craftsmen, from beast spirit users to soldier spirit users. This surprised Zhao Hai.

However, it could be seen that this campsite was only a temporary campsite because it was full of tents. There was no fence built here, and it was just an open campsite.

When they arrived at the camp, Ganya had someone arrange a tent for Zhao Hai. After Zhao Hai put down his things, Ganya sent someone to invite Zhao Hai to have a meal. The dining place was on the open space of the tent. Other than Ganya, his son, and his subordinate, there were many other people attending. These people included botanists, craftsmen, beast soul users, and soldier soul users. However, it could be seen that these people all had extraordinary identities. They were considered the left and right arms of the Grand Duke Ganya.

After Zhao Hai entered the tent, Grand Duke Ganya invited him to a table to his left. The others did not have much reaction. Zhao Hai was not the Grand Duke's subordinate. He was only here to help, so he should be treated with such courtesy.

After Zhao Hai sat down, Grand Duke Ganya raised his glass and said in a deep voice, &Quot; everyone, this incident in the ancient eastern plains has a huge impact on the northern Alliance. Today, we have specially invited Mr. Zhao Hai to help us. Let's all give him a toast. &Quot;

Of course, Zhao Hai could no longer use his Tian He Cao name. He returned to his original name, Zhao Hai. No one would suspect him anyway.

"You're too kind, Grand Duke. I'm sorry, I'm sorry." Zhao Hai quickly raised his glass.

&Quot; Sir, since you're here, you deserve this glass of wine. Come, cheers! &Quot; gan ya smiled. After he finished speaking, he drank the wine in his glass in one gulp. The others also drank their wine.

Grand Duke Ganya put down his wine glass and looked at Zhao Hai."Sir, when you came here today, you took a look at the grassland and seemed to have found something. Can you tell me?"

When Grand Duke Ganya said this, everyone's attention was focused. Everyone looked at Zhao Hai, wanting to hear what he had to say.

&Nbsp; Zhao Hai smiled, " Grand Duke, your eyes are really sharp. I really did see something. I think it might have something to do with the situation here in the ancient eastern plains. &Quot;

When everyone heard what he said, there was an uproar. All of them were gan ya's most capable men. The strength of the botanists was not weak, but they had been watching for so many years and had not found anything. Now Zhao Hai said that he had found something, which really surprised them.

Archduke Ganya glanced at his subordinate and said in a deep voice,"Be quiet, let Mister finish." Those people all quieted down, but the botanists under gan ya looked at Zhao Hai with some hostility.

Zhao Hai did not seem to notice their expressions. He said in a deep voice, " Grand Duke, you've only been paying attention to whether the grass is sick or harmed, but you didn't notice the environment here. I think the situation here is entirely caused by the environment. &Quot;

"What a load of nonsense!" As soon as Zhao Hai finished speaking, a voice was heard, " "The eastern ancient grasslands is one of the best grasslands in the northern Alliance. The environment here has always been the best. The weather has been good all these years. That's simply nonsense."

Zhao Hai looked towards the source of the voice, and saw that it was one of the botanists under gan ya. This botanist's strength was not weak, and from the aura he was emitting, he should be a consolidated tier botanist. Furthermore, he was seated at the front, and it seemed that he had the trust of the Grand Duke gan ya.

Archduke Ganya glanced at the man and said in a deep voice,"Alright, Chen Lian, let Mr. Zhao Hai finish." The botanist snorted and stopped talking. Grand Duke Ganya turned to look at Zhao Hai and said,"Please continue, Sir. To be honest, I would also like to know why you said that the eastern ancient grassland became like this because of its environment."

Zhao Hai smiled, " Grand Duke, you've mentioned a few times that the eastern ancient grassland is very important to you. That's why you're taking care of it. If I'm not wrong, you've probably killed all the wolves, snakes, and the like. &Quot;

Hearing Zhao Hai's words, gan ya and the others were stunned, especially the few beast Spirit Masters. They looked at Zhao Hai in confusion, not knowing why Zhao Hai suddenly mentioned wolves, snakes, and the like. Shouldn't these belong to the scope of beast Spirit Masters?

Zhao Hai looked at the crowd and smiled. &Quot; "I know that everyone is saying that wolves and snakes are all animals and are all under the management of beast Spirit Masters. But you must know that the relationship between plants and animals is very close. If the plant is damaged by insects, then does it belong to the management of beast Spirit Masters or the management of Plant Masters? Most people would think that this is, of course, managed by botanists, but don't forget that insects themselves are also animals, aren't they?"

Everyone nodded thoughtfully. Zhao Hai continued, " &Quot; everyone might not have noticed, but here in the eastern ancient grassland, there are many rabbits and rats. There are also many flies here. These are not normal. &Quot;

Hearing Zhao Hai's words, Grand Duke Ganya's expression turned serious. He looked at Zhao Hai and said, " "Please speak clearly, Sir."

Zhao Hai said in a deep voice, " &Quot; all animals have their natural enemies. In an area, if an animal doesn't have its natural enemies, it's a very scary thing. Even if the animal doesn't have any offensive power and is very unremarkable, it might be good for people. Take the eastern ancient grassland for example. There used to be a very complete annual food chain here, and that is mice and rabbits eating grass and insects. Snakes and wolves eat mice and rabbits. The feces of all the animals in the Prairie became nutrients for the grass, but these feces need to be decomposed by a small insect before they can become nutrients for the grass. Now, because you place too much importance on the environment of the eastern ancient Prairie, you killed most of the wolves and snakes. This way, the mice and rabbits have no natural enemies. Without their natural enemies, these two animals that reproduce very fast will produce in large numbers, and slowly, the number of mice and rabbits in the Prairie will increase."

At this point, Zhao Hai paused. He looked at his subordinate who was listening attentively and said, " &Quot; when there are more rats and rabbits, they need to eat grass, and they will eat the roots. At the same time, they will dig holes in the grassland and destroy the roots. When the roots break, the grass will naturally die. Then, more rats and rabbits will eat more grass and insects, and more and more grass will die. Without the decomposition of the insects, more animal feces will be produced, which will attract more flies. Even the feces will destroy the grassland. The grass here in the eastern ancient grassland will die on a large scale, and the number of mosquitoes and flies will increase."

Everyone looked at Zhao Hai in a daze. They never thought that Zhao Hai would give such an answer. To be honest, this was the first time they had heard of such a theory. Everyone was stunned, wondering if Zhao Hai's words made sense.

After a long while, Archduke Ganya suddenly stood up and strode out. As he walked, he said, &Quot; everyone, follow me. I want to see if it's really as Mr. Zhao Hai said. &Quot; When Zhao Hai saw the look on Grand Duke Ganya's face, he could not help but smile bitterly. He really did not expect the Grand Duke to be so impatient.

However, he did not say anything. He just stood up and followed Duke Ganya. He was confident in his judgment because his power of the will could clearly feel that there were too many rats and rabbits under the ancient Eastern grassland. There was animal feces everywhere, but there were no wolves, snakes, or dung beetles. That was why he had such a judgment.

After a while, they arrived at a patch of withered grass. Grand Duke Ganya turned to look at a beast spirit beside him. The beast spirit immediately understood what Grand Duke Ganya meant. He stretched out his hand, took out a small flute from his body, and began to play it gently.

The sound of his flute was very strange, and it made people feel very uncomfortable. But slowly, Zhao Hai felt the grass shake as if something was hitting it. Soon, a large group of rats came out of the grass.

There were hundreds of these rats. Seeing so many rats, everyone felt their scalps go numb. It should be known that these rats all ran out of the grass. It was just a small grass field, but there were so many rats. It was too surprising.

Grand Duke Ganya looked at the rats with an ashen face. In the end, he snorted in anger and waved his hand. A ball of energy flew over, and the rats were instantly reduced to ashes and disappeared.

After killing the rats, Grand Duke Ganya's expression improved. He turned to look at Zhao Hai and said with a bitter smile, " &Quot; Sir, I'm sorry. I didn't expect that our biggest headache would be this. It's actually caused by ourselves. The scariest thing is that we didn't know about it. Sigh, this is really unexpected. &Quot;

Zhao Hai smiled and said, " you can't blame the Grand Duke for this. People usually solve the problems between animals and plants separately, so no one would have thought that these problems were caused by animals. I already had some speculations when I was at the Grand Duke's residence. I'm only here to verify it. Once I find a problem, it's easy to solve it, isn't it? "

&Quot; that's right, " Grand Duke Ganya laughed. &Quot; it's easy to solve the problem now that we've found it.
