Zhao Hai's life was very peaceful, but the lives of the people on the literature continent were not so peaceful, because this time, the literature continent had really encountered a huge crisis.

Many coastal cities on the continent had already fallen. After all, very few cities could survive the attacks of the sea tribe's powerful Water-type spell techniques.

Additionally, those sea tribes could also go downstream. As long as the water could reach them, they would attack. People on the literature continent had not seen such an attack before.

The people from the literature continent had only fought with the destroyers before. The destroyers usually came from the sky, and the people from the literature continent had a way to block those destroyers from the sky. They also had Masters at the Wu Kong level, who could block those destroyers.

However, the sea tribe coming from the water made the scholars on the land of literature very distressed. They never thought that the world above the water belonged to the human race, while the world under the water belonged to the creatures in the water. It was impossible for people to stay in the water for a long time, which greatly limited human's research on the underwater world.

But now, the people of the sea tribe were attacking from the water. Under such circumstances, it would be very difficult for the people on the mainland to defend against their attacks.

If the sea tribe attacked from underwater, the people on the literature continent wouldn't be able to know where they were going to attack from. All of this made the people on the literature continent very distressed.

In the end, they had no choice but to guard every city by the river. At the same time, they set up surveillance ships in the coastal road to pay attention to the situation in the water at all times. However, there were huge disadvantages to doing this. The first disadvantage was that the forces were scattered.

They had to send people to guard many cities, so that they could concentrate their forces on the enemy. However, the enemy could concentrate their forces on only one city. This was a very big weakness, which could be easily taken advantage of by the sea Race and destroyed one city at a time.

The second disadvantage was that there were too many surveillance ships, but not many surveillance methods. This way, not only would the surveillance effect be very low, but it would also cause the river to be blocked, making it very difficult for the water transportation in the literary land.

The water transportation industry was very developed on the land of culture, because it was faster and more efficient than the land. It consumed less energy. It could be said that the water transportation industry had always been the bloodline of the land of culture.

But now, it was different. Because of the surveillance ships, the water transportation industry in the continent of culture had been greatly affected. The speed of the ships had slowed down, and some places couldn't even be crossed. This caused the cities in the continent of culture to be in a certain shortage of materials.

In addition to the surveillance ships making the water transportation more difficult, there was another reason that caused the inconvenience of the water transportation, and that was the existence of the sea tribe.

The sea tribe had always lived in the water. Even if there were surveillance ships, there was no guarantee that they could find all the sea tribe. After the surveillance ships were set up, there would still be incidents of the sea tribe attacking cargo ships in the major rivers of the literature continent from time to time. Some cargo ships were lucky and managed to save their ships, while some cargo ships had already been destroyed and people died.

It was because of these situations that the Civil continent was really in danger this time. They couldn't gather the entire continent's forces to fight the enemy like they did with the destroyer, because it was impossible. When the sea tribe retreated, you couldn't find where they went. How could you fight them in that case?

In addition, there was no circulation of materials and their forces were scattered. It could be said that the culture continent was at a complete disadvantage in the battle against the sea tribe. This caused the people of the culture continent to feel a great headache.

However, none of this had anything to do with Zhao Hai. He was now in the guqin music Academy in luoxia city, reading books every day. He was very free. Seven days had passed. Apart from some small-scale attacks, no large-scale attacks had been detected by the sea tribe. This gave the people on the land of literature even more headaches. Now, the entire land of literature was tense, but the sea tribe was only making small fights. They couldn't take any small fights lightly. This situation made the people on the land of literature feel extremely painful, and they were almost going crazy.

At this moment, the river-breaking expert of the literature continent made his move. Of course, no one knew how he did it. People only knew that he had made his move. One month after luoxia city was attacked, all the academies on the literature continent received a notice from the river-breaking expert. The river-breaking expert told them that they could relax now, because they had made an agreement with the sea tribe. As long as he didn't go 10000 miles away from the sea of the literature continent, he would be killed. The sea tribe wouldn't attack them at will, and they wouldn't take the initiative to attack the Civil continent.

Upon receiving this news, everyone on the continent of literature heaved a sigh of relief. This news was too important for them.

Zhao Hai had also heard the news. To be honest, he was really shocked when he heard it. He had not expected that the river-breaking level Masters in the literature continent would take action so quickly.

However, this was good news for Zhao Hai. He had come to the guqin music Academy to learn music. Now that the Academy had finally returned to normal and he could finally learn music, he was naturally very happy.

After the entire continent received the news, they completely relaxed. They began to rebuild after the war. Fortunately, they didn't have to worry about the water transportation problem, so the cities didn't lack resources. The reconstruction after the war was very fast.

Peace was finally restored on the land of literature. However, the attack of the sea tribe also reminded the people on the land of literature that their control in the water seemed to be lacking. In this case, the scholars on the land of literature immediately began to discuss how to solve the problems of underwater defense and surveillance.

Zhao Hai had also heard about this matter recently, but he didn't want to get involved. After all, the literature continent was not the soldier soul continent. Even if it was the soldier soul continent, he wouldn't care about anyone else other than the HU family. So, Zhao Hai really didn't care much about the affairs of the literature continent.

However, even if he didn't care, someone wanted him to. A month after the alarm was lifted, the guqin music Academy finally completed the post-war reconstruction of luoxia city. Classes resumed as usual. At this time, Zhao Hai was once again invited to LAN Zhi's office. After the two sat down, LAN Zhi looked at Zhao Hai and smiled,"Sir, classes have resumed at the Academy. I wonder if you have any requests?"

Zhao Hai shook his head. &Quot; No, thank you, Mr. Lan. I'm just here to study, so I don't have any requirements. &Quot;

LAN Zhi nodded. He then looked at Zhao Hai and said, " "Mr. Zhao Hai, I'm here today on behalf of the entire continent of literature. I need your help."

Zhao Hai was stunned when he heard LAN Zhi's words. He looked at LAN Zhi in confusion and asked, " &Quot; please speak, Mr. Lan. I'll definitely help you if I can. &Quot;

LAN Zhi nodded and said in a low voice, " &Quot; thank you in advance, Mr. Lan. Mr. Lan, it's like this. You're also saying that we've discovered many shortcomings in the battle with the sea tribe, especially in the underwater surveillance. The sea tribe can move freely in the river as if no one was there. This is a huge safety hazard to the mainland, so we would like to ask Mr. Zhao Hai for your help. See if you can improve an underwater plant to help us monitor underwater. Do you think it's okay?"

When Zhao Hai heard LAN Zhi's words, he was stunned. Then, he looked at LAN Zhi and said, " "Mr. Lan, are you joking? We've thought about improving the underwater plants before. However, there's a big problem, namely, how to observe the underwater plants. If we want to improve a plant, we must observe it for a long time and remember the details of its growth. However, how do we observe the underwater plants? Without a long period of observation, it is impossible to improve a plant." Although Zhao Hai said that, he was actually moved. People from the mainland were not allowed to observe underwater plants, but that did not mean that Zhao Hai could not. When Zhao Hai entered the ocean, he had been focusing on the Marine animals and had completely neglected the Marine plants. It was only when LAN Zhi made this request that Zhao Hai remembered that there were many marine plants in the ocean. If he were to collect a large number of marine plants, he would be able to collect them. That would definitely be of great benefit to his space.

However, he could not tell LAN Zhi that he could do it. If he did, LAN Zhi and the others would suspect him. That was why Zhao Hai specifically said that he could not do it. He wanted to see how LAN Zhi would react.

As expected, when LAN Zhi heard Zhao Hai's words, he immediately revealed a smile and said, " &Quot; Sir, of course we know this. We've already thought of a way to deal with this when we came to ask for your help. Perhaps you're not familiar with the cultivation methods of US scholars. In fact, some of US scholars can live in the water for a long time. This is related to their souls. Some of their souls are very special and can allow them to move freely underwater. However, there are too few people like this. It's impossible to form a strong combat force, but it's not a problem to take a few people to observe the plants in the water. So, if you really want to observe the plants in the sea, it's not impossible."

When Zhao Hai heard what LAN Zhi said, he was truly shocked. He looked at LAN Zhi and said, " "Is what teacher said true? Can you really let people observe the plants underwater for a long time? "If you can really do this, it's not impossible to improve those underwater plants. But you have to think clearly that even if you improve those underwater plants, they might not be able to play such a big role. Perhaps, they might fail in the end. These things can happen. If you can accept this situation, I can do my part. If you want to have underwater plants, everything will be fine. Then I advise you not to waste your time."
