54 people went in, 24 people came out, everyone who came out was injured, some went crazy, and only a few people were lucky enough to get the treasure, and this result shocked all the martial emperors.

After careful questioning and analysis, several martial emperors roughly understood the truth of the matter. It turned out that the black qi in the undersea palace was harmful, and the low-level martial marquis was weak and could not resist it, and all of them were killed. The third-order martial marquis could barely resist, but he would suffer heavy casualties. Only high-level martial artists and above can resist the erosion of black qi relatively safely.

This is the reason for the death and injury of the martial marquis, but it is not that the stronger the strength, the better, because in addition to the black qi in the undersea palace, there are also some warriors who were eroded by the black qi in ancient times. Like zombies, they will attack the intruding warriors, so the high-level martial princes and low-level martial kings will also be killed and injured.

Among these corrupted warriors, there is a particularly terrifying existence, that is, the devil in their mouths. He specialized in killing middle and high-level martial kings, and the stronger his strength, the more interested he became, so the 9 high-level martial kings were almost slaughtered by him, and nearly half of the third-order martial kings died.

It is precisely because of the existence of black qi and devils that the martial artists who are too weak and too strong have suffered heavy casualties, and only the high-level martial marquis and low-level martial kings in the middle of the strength have the highest survival rate.

After figuring out the situation, the 9 Martial Emperors discussed it carefully, and finally decided to join forces to enter the undersea palace and work together to solve the devil inside.

This time, the result was once again unexpected by everyone, 9 Martial Emperors entered, but each of them came out seriously injured, and the audience was in an uproar!

"This black gas is actually that kind of thing!" Xue Ye, who had just come out, looked at Feng Xiangqing in shock.

"Could this be the reason for the fall of Feng Wu?" Yan Lei also felt very incredible.

Feng Xiangqing nodded silently.

"Who is the devil in there, it doesn't look like the kind of thing in legends!" Feng Wuji asked with a sigh of relief.

"I don't know!" Feng Xiangqing shook his head and said.

The devil's strength is far superior to the 9 of them, and he has no idea where the devil comes from!

Not long after the 9 Martial Emperors came out, the Undersea Palace began to sink, and then disappeared quickly, no matter how you look for it, you can't find it.

This is the first time that the undersea palace has been born, and it has brought countless shocks to the world, making the entire East China Sea boil for a long time.

In the year 1102 of the East China Sea Era, nearly 100 years after the first appearance of the Undersea Palace, the already forgotten Undersea Palace appeared in front of the world for the second time.

The East China Sea shook again!

This time, the 9 Martial Emperors joined forces again, but the result was even worse than the first time, not only were they seriously injured, but one almost couldn't get out!

Such a result made the 9 Martial Emperors completely desperate. Since then, the 9 Martial Emperors have never entered the Underwater Palace again, and it has been agreed that every time the palace is born, 9 people from each domain will be selected to go on an expedition, including 3 fourth-order martial marquis, 3 fifth-order martial marquis, and 3 low-level martial kings.

It turned out that the decision of the 9 Martial Emperors was correct, and the devils in the undersea palace would not take the initiative to attack the low-level Martial Kings and the martial artists below the strength. When such a combination of 9 people enters the undersea palace, it can basically ensure that more than 8 percent of the warriors can get out smoothly, and most of them can find good treasures or get good opportunities.

Since then, every time the Undersea Palace is born, each domain will abide by the initial agreement, and the major families have selected 3 Fourth-Order Martial Princes, 3 Fifth-Order Martial Princes and 3 Low-Order Martial Kings, and then entered the Underwater Palace together to explore.

The third underwater palace was inaugurated in 1186, 84 years after the second.

The fourth underwater palace was created in 1263, 77 years after the third.

The fifth underwater palace was created in 1331, 68 years after the fourth.

The sixth undersea palace was born in 1391, 60 years after the fifth.

The seventh underwater palace was inaugurated in 1442, 51 years after the sixth.

There was no pattern in the previous few times when the undersea palace was born, and each time the 9 major families prepared in a hurry. However, with the increase in the number of appearances of the Undersea Palace, people have gradually found a pattern, that is, each appearance of the Undersea Palace is always about 8 years earlier than the last one. In other words, the 8th Undersea Palace is most likely to be born in 1485, so the nine major families of the East China Sea moved one after another at the beginning of this year and began to prepare for this major event related to the entire East China Sea!

Also in January 1485, the Eastern Sea Era, Ghost City on Ghost Island in the Ink Domain also launched a fierce selection competition. The high-level martial marquis and low-level martial kings who came to the 18 major islands of the ink domain gathered in Ghost City!

In terms of low-level martial kings, in order to ensure the safety and stability of the team, Mo Zhai personally designated Mo Ting, who was the strength of the second-order martial king, to participate in the operation of the undersea palace, command the remaining 8 people, and be responsible for the safety of the whole team. After that, Cao Jian, who was a first-order martial king strength, was appointed to assist Mo Ting and jointly lead this crucial operation.

Mo Ting is old and strong, Cao Jian is strong, these two people are the absolute core of the entire Mo Yu team, and both are indispensable. Therefore, among the low-level Martial King candidates, only the last first-order Martial King position is left to compete for.

For this position, Mo Zhai also made some restrictions, that is, only young martial kings younger than 60 years old were allowed to participate, in order to give them the opportunity to practice.

In the East China Sea region, there are very few people who become kings before the age of 50, but there are still many people who become kings before the age of 60. In the Moyu, Feng Xiao, Bai Liyi, Ning Jun and Yan Xu and others all became kings before the age of 60, and they are the newly born martial kings in the Moyu in recent years!

Feng Xiao, a descendant of the Feng family, one of the 9 major foreign surname families in the Moyu, the champion of the Moyu Dabi 6 and a half years ago, won the title of the first of the ten generals, and now he is a first-order martial king, with a stable realm and strong strength!

Baili Yi, a child of the Baili family, one of the 9 major foreign surname families in the Moyu region, was the runner-up in the Moyu Dabi 6 and a half years ago, the second of the ten generals, and now he is also promoted to the king of martial arts, following in the footsteps of Feng Xiao!

Ning Jun, the son of King Ning of Jindao, is now a father and son king, and he is glorious for a while. In the previous Moyu Dabi, Ning Jun didn't have time to participate, otherwise there would be a place for him among the ten generals!

Yan Xu, a native of Xisen City, a new generation of martial kings, is the glory of the Yan family in Xisen City, making the Yan family officially a king family, and the first person in the history of the Yan family!

The four freshman martial kings competed for a position, and the competition was fierce. In the end, Feng Xiao relied on his strong strength to win three battles and three victories, and successfully won this final place!

Since then, the three low-level martial kings have been officially determined, namely Mo Ting, Cao Jian and Feng Xiao.

In terms of fifth-order martial artists, there were a total of 7 martial artists who came to participate, namely Mo Tan, Mo Yu, Wu Jimang, Ye Danling, Nalan Qiu, Long Xinru and Zou Kai.

Mo Tan, the son of a branch of the Mo family's ancestors, his father Mo Shannan helped Mo Zhai sit on a big island, in terms of generation, Mo Tan and Mo Zhai are still the same generation, but the age difference is dozens of years. As a woman, Mo Tan's achievements are beyond the reach of many male warriors. In the Moyu Contest 6 and a half years ago, she overpowered Mo Yu and won the third place in the Moyu Dabi, the third of the ten generals!

Mo Yu, a disciple of the Ghost Academy, is invincible under the Martial King, and at the same time, he is still the fourth in the Moyu Dabi 6 and a half years ago, and the fourth of the ten generals. In the past, he was defeated by Mo Tan, but today Mo Yu has surpassed his opponent and truly become the first person under the Martial King!

Wu Jimang, a son of the Wu family, one of the 9 major foreign surname families in Moyu, was the fifth in Moyu Dabi 6 and a half years ago, and was the fifth of the ten generals. As the son of the strongest family among the 9 foreign surname families, Wu Jimang's strength is also very strong, second only to Mo Yu and Mo Tan and others!

Ye Danling, a disciple of the Thundercloud Sect, was the sixth in the Moyu Dabi 6 and a half years ago, and was the sixth of the ten generals. Now, his status in the Thundercloud Sect is the same as that of Mo Yu in the Ghost Academy, he is also under one person and above ten thousand!

Nalan Qiu, a son of the Nalan family, one of the nine major foreign surname families in the Moyu region, is the younger brother of Naland, the owner of Coconut Island. Six and a half years ago, Nalan Qiu was just overage and could not participate. Now his strength is also close to the peak of the fifth-order martial marquis, and it is completely not to be underestimated!

Long Xinru, from the ghost island of Youquan Harbor, is a well-known female warrior. She is low-key, does not like to fight in public, and did not participate in the Melody Contest of six and a half years ago. However, this time, she took the initiative to participate in the competition for the place in the Underwater Palace, which was quite surprising!

Zou Kai, from the three secluded cities of Ghost Island, is a battle maniac who likes to be accompanied by monsters and beasts, and has a strong wildness. I don't love false names, I love treasures, and I'm an out-and-out collector!

7 people, all of them are the best of the fifth-order martial marquis. Of course, if you look at the entire Ink Domain, there must be more than a few people with the strength of a fifth-order martial marquis.

The reason why only 7 people participate in the qualification competition for the undersea palace is mainly due to two reasons, one is Mo Zhai's age limit, and only martial artists under the age of 60 can participate;

Due to the above reasons, only 7 people came in the end. Seven people compete for 3 spots, which means that everyone has about half of the chances.

After a circular battle, Mo Yu, Mo Tan and Ye Danling won in the end and successfully won the qualification to enter the Underwater Palace. Among them, Mo Yu won all 6 battles and continued to defend his title of invincible opponent under the martial king; Mo Tan won 5 of 6 battles and only lost to Mo Yu once; Ye Danling won 4 victories and won the last place.

Like the Yan Domain, the Mo Domain also selected 2 fifth-order martial artists as alternates. Nalan Qiu originally had a chance, but he gave up, and he chose to leave Ghost Island with Ning Jun and continue to discuss the great cause of becoming a king. Therefore, the last to enter the waitlist are Wu Jimang and Long Xinru.

Finally, there is the fourth-order martial marquis side. Among the many martial artists who signed up, there was a third-order martial artist who was particularly conspicuous, and he was naturally Lan Qian. No one had any objections to Lan Qian's registration, and the battle with Mo Yu was there, and no one dared to despise this third-order martial marquis.

In addition to Lan Qian, there were also 7 fourth-order martial marquis who also participated in this competition. This situation is the same as that of the fifth-order martial marquis, on the one hand, there is an age limit, and only martial artists under the age of 50 can participate. On the other hand, there are many dangers inside the underwater palace, and if you enter, there is a 20% chance that you will not be able to get out! Therefore, some people are reluctant to take this risk.
