After the simple deployment of the underwater defense measures, Xiao Yu carefully searched the nearby waters and cleared out a few small groups of assault fish and some aquarium monsters, but did not find too much threat. The continuous effect of the underwater breathing agent was about to pass, and the four people returned to the shore.

Xiao Yu said: "After we put these things under the water, we should be able to detect the invasion of the sea clan in advance. After a few days, we will put the goblin submarine into use to patrol nearby waters and ensure the safety of Wentian City."

Han Kexin said: "I want to go to the inspection room to see the situation of the sea clan, which will give me some insight."

Xiao Yu nodded and said, "Okay, I just want to take a look. Xiaowen, Yunyun, come and have a look."

Xiao Yu and the four returned to the inspection room to check the situation on the west coast. The sea clan did not find the magic eye hidden on the cliff. From a distance, the crystal clearly reflected the current situation on the west coast. Thousands of sea clan warriors were in order. Some went to the sea to catch fish and shrimp, some hunted nearby monsters, and some built buildings on the beach. At this time, most of the simple tents and houses had been built, and a barrier was made in the outer east, and the entire coast turned into a sea clan village.

"They are hunting sea beasts!"

The blue and calm sea water stirred up huge waves, the mud and sand were surging up, the sea water was not clear, and blood dyed a large area of ​​sea area light red. Another giant wolf rose up, hundreds of fishmen were rolled away. After the waves fell, a black giant whale of dozens of floors of buildings exposed to the water.

The huge black whale was filled with the steel forks of fishmen. A huge net was used to catch it. Hundreds of rope guns were inserted into the black whale's body. Nearly a thousand fishmen warriors pulled down a little bit to the shore at the same time, and blood poured out from several major wounds on its body. As the giant whale struggled, huge waves soared into the sky and flooded half of the sea clan village, destroying many newly built buildings, but did not cause much damage to the sea clans.

The black giant whale was too powerful, and nearly a thousand fishman warriors could not subdue it immediately. The nearby sea warriors immediately went up to support him when they saw this. All kinds of water magic and sea martial arts were called up. The black giant whale was covered in bruises. The black giant whale twisted its body angrily, and the spiral waves appeared all over the body and instantly tore the bodies of dozens of sea warriors, but this did not reduce the attacks of the sea tribes, and more magic fell on it.

Jiang Xiaowen covered her little mouth and exclaimed: "This whale is so big and powerful. More than a thousand fishmen and so many other sea people can't kill it immediately!"

Xiao Yu frowned and pondered: "This is a fourth-level monster, but from the moment he was dragged ashore by a fishman, his death was basically destined. After all, more than a thousand sea warriors, although most of them are first-level and second-level low-level and intermediate-level warriors, and their combat power is quite amazing, not to mention that there are many third-level fishman warriors. Even if the giant whale is a powerful fourth-level monster, it is just an ordinary monster after all, and it is impossible to withstand the siege of so many sea tribes."

The sea warriors organized the attack in an orderly manner. The black giant whale gradually disappeared under the wheel-like attacks. After the magic power was exhausted, it completely lost its ability to resist. The fishman mage called up several third-level magic and finally disintegrated the last little resistance of the black giant whale. It completely collapsed to the ground and was still slaughtered.

The sea tribe was in full swing. Thousands of sea tribe warriors saw the black giant whale falling down. They were not afraid of their hands but rushed up. In a short while, the huge black giant whale was cut open and all kinds of internal organs were continuously transported out. The fishman took it to feed the monsters, and the whale meat was cut and stored. Thousands of fishman cut off the whale's bodies one by one like ants.

Yun Yun was shocked by the power and huge number of the sea clan. "Their number is too many, almost dozens of times that of Wentian City. There are probably thousands of third-level strength, and there must be fourth-level sea clans... Both in terms of strength and quantity, they are all overwhelming advantages!"

Han Kexin frowned and said, "Actually, the strength of the enemy is not terrible. The most terrifying thing is that they are a group of wise creatures who know how to cooperate and know how to tactics. With the power of this sea tribe, it is easy to capture Wentian City... We are in big trouble this time!"

Xiao Yu also expressed his solemn expression: "We are thousands of miles away from the west coast. We can arrive in one or two hours with our speed. The sea tribe will probably not be much slower than this speed when coming to Wentian City from the water. It would be too easy if they wanted to attack Wentian City."

"What should I do? Wentiancheng has finally developed to its current prosperity. We can't just lose it." Jiang Xiaowen looked at Xiao Yu and said, "Do you have any good solutions?"

"No, I'm not a god. The enemy is enough to easily crush us ten or a hundred times in terms of strength. Once such a huge battle starts, no matter how good the strategy is, it is useless. The difference in strength is too large. Any trick will be vulnerable in the face of absolute strength."

Jiang Xiaowen was unwilling to accept this fact, her eyes turned red suddenly and she hurriedly said, "There must be a solution! Do we have to give up Wentiancheng? I don't want to leave Wentiancheng, don't..."

Han Kexin supported Jiang Xiaowen and said, "Silly girl, who said she would give up Wentiancheng? This sea tribe just fled to the coast for refuge, not to take revenge on Wentiancheng. They only plundered for daily necessities, so the target range would be large. Even if they attack Wentiancheng, they would send at most a fishman army. Wentiancheng is not a big place, and there is nothing particularly important to them. It is impossible for the sea tribe to come in full bloom."

Jiang Xiaowen felt that this was reasonable and felt a little relieved.

Xiao Yu added: "With the size of the sea tribe, even if you send a small army, the scale of the siege battle will be better than any previous one. Their number is conservatively estimated to be around 100,000 to 200,000, and there are thousands of third-level people. Any army is a terrible legion. Moreover, once the attack is frustrated, the sea tribe will inevitably launch a larger war in a short time, and Wentian City cannot withstand several rounds of attacks. Our situation will be very dangerous. The strength of you several people must be improved to the third level as soon as possible. Zhao Changping must also solve the endgame of Leiming City as soon as possible and guard Wentian City. Only by being a little sure enough to resist the invasion of the sea tribe."

Han Kexin said: "Since the sea tribe has just landed, it should need a transition period to gain a foothold. They will definitely not make much noise in the next few days. We should seize the precious time of these days. Xiaowen and Yun Yun, I will lead your advancement task personally. I will take you to the plains and let you advance in a few days."

Xiao Yu nodded: "I will go to the West Coast in person to investigate the specific situation of the sea people."

Han Kexin and Xiao Yu briefly discussed and agreed with the other party’s idea.

Xiao Yu said, "Okay, let's take action separately. The northern plains are very dangerous, so you must pay attention to safety." Xiao Yu took out a few scrolls to the city and handed them to the three of them and said, "This is a very precious scroll to the city. We don't have a few left. Don't use them until they have no choice but to come back as soon as possible."

Han Kexin couldn't help but feel a little moved, "Don't forget to bring one with you. Your trip is probably much more dangerous than ours."

"Don't worry, one has been left." Xiao Yu nodded and said, "Actually, with my current speed, even if I meet a powerful opponent, I can't beat it, but it's more than enough to escape. This trip is just for the purpose of reconnaissance and not proactively test it, so there should be no danger."

Han Kexin said with concern: "Since that's the case, then that's OK... But no matter what, it's always right to be careful."

Jiang Xiaowen also said, "Yes, although you are very strong, you can't be careless."

Xiao Yu nodded and said, "I have a sense of responsibility."

Yun Yun looked at Jiang Xiaowen and Han Kexin and suddenly felt envious. At least they could care about Xiao Yu from the bottom of their hearts without any worries. Yun Yun also wanted to say something, but she always felt that there was still a slight gap between herself and Xiao Yu, or something was separated, so she had to give up.

After the several people divided the work, they immediately took action.

Xiao Yu opened the secret realm stone he just obtained in the Epic Tower. A new level-first basic secret realm appeared in the city to arouse everyone's interest. The difficulty of the level-first secret realm is very low, not to mention that it is a resource-based secret realm, and everyone couldn't help but compete to challenge the secret realm first.

They are now completely unaware of the large-scale invasion of the Western Sea tribes, and they don’t know what everyone will react when the news is announced. I’m afraid they all want to go to other cities to take refuge.

Xiao Yu thought about it carefully.

Early warning puppets and mines can effectively detect and block the sea clan for a while, but Xiao Yu is very clear that fighting in the water, the combat effectiveness of various sea clans such as fishmen will be doubled, and humans will be greatly reduced in the water. They cannot be opponents of the sea clans. Therefore, the key to fighting the invasion of the sea clans is still the battle on land. The main purpose of water defense is to discover the invading sea clans as soon as possible so that Wentian City can make corresponding preparations. Defense on land is the key to resisting the sea clans.

Xiao Yu ordered that the city be mobilized to mobilize all the Niutou monsters and use them as coolies to dig and carry huge stones to build a defensive city wall in front of the lake in front of the south city gate. This is a big project, and the construction of the city wall cannot be completed in one or two days.

Wentian City is still immersed in the joy of winning the success of Demon Wolf City. Everyone did not realize that an unprecedented terrible crisis was brewing in the West, and disaster was approaching quietly.

Xiao Yu asked everyone to keep the landing of the West Coast Sea Clan for the time being confidential, leaving Du Tao to manage everything in the city as usual, and he secretly left Wentian City and went west alone to investigate.
