The sea shuttle slowly dived, the pressure gradually increased, and everyone in the cabin felt different degrees of oppression. When they descended to the sea level, the little monks in the Qi cultivation period couldn't bear it, and the four Jindan stage monks cast spells to prop up a spiritual power shield around their fingers, so that they would not be oppressed by the pressure and couldn't stand upright. When they descended to five hundred zhang underwater and were about to approach the bottom of the sea, foundation-building period monks like Qin Guan and them couldn't support it. Up to now, it can be seen that among the people in the foundation building period, the depth of their cultivation has become shallow: first, Gu Weirui and He Lianjun couldn't support it, and the two of them didn't hold it strongly, and they felt that they were powerless to resist, so they ran into the shield that Liao Xingchen and others held up for the disciples in the Qi training period; Although Qin Guan is not the top among the foundation building monks, as a monk in the middle stage of foundation building, he is undoubtedly the most solid foundation, so he has persisted for the longest time, seeing that he is about to touch the underwater ground, he still has some spare strength, but his face is flushed, as if he has drunk a lot of old wine.

The shuttle sank for almost an hour and a half before it touched the ground, and the hull trembled slightly, and then stopped. If it weren't for the fear that it would fall too quickly, people with shallow cultivation would not be able to support it, and it wouldn't have taken so long. It was Dong Xiuzhu who operated the boat, although his cultivation was not high, but fortunately, Gu Qinfang had Gu Qinfang by his side to support him alone with a spiritual power shield, and it was not a big problem. However, he probably didn't feel anything else, he was so focused on the rudder in his hand and around the sea shuttle that he didn't feel the oppression in the water at all.

"Whew-" Dong Xiuzhu let out a long breath and lay down on the chair a little limply. The process of descent made him struggling, and it was relatively simple to manipulate the sea shuttle to move quickly and horizontally in the water, but it was not easy to descend slowly, after all, not only more and more sea beasts, but also some objects floating in the water could make him nervous for a long time. After all, the sea shuttle is a sea ship designed for dozens of feet underwater, not a deep-water submarine for underwater archaeological exploration, Dong Xiuzhu is also worried that the hull is not strong enough to withstand so much pressure underwater. Fortunately, the sea shuttle survived, and it was not a waste that they spent almost a quarter of the spiritual materials of the sea city to build this sea ship.

Because the underwater environment is unpredictable and not quite the same as the situation on land, it is necessary to send a few people as an advance team to investigate. And because the ship still needs a Jindan monk to sit in the seat to withstand the pressure on the others, the advance team can only be led by Qin Guan, plus Shu Tong, a demon monk who is about to condense the demon pill.

A person and a demon slowly felt out of the cabin, and used their spiritual sense to explore the surrounding terrain little by little, anyway, it is now at the bottom of the sea, there is nothing special, and basically there will be no monks. You must know that the Terran monks are extremely resistant to going to the bottom of the sea, one is because of the pressure in the water, and the other is because at the bottom of the water, in addition to the spells of the water system, other means are greatly restricted, not to mention that some monks practice exercises with their own fire spells, and their combat effectiveness will be reduced to full ten under the water, leaving only the magic weapon in their hands to resist the enemy.

One person and one demon are slow, and it is already difficult to support an area around them to breathe, let alone drag this area to move, but fortunately they have plenty of time, anyway, there is no one around, and they are not afraid that others will find out about the two of them.

After touching the bottom of the sea for half an hour, Shu Tong didn't find anything at all, and was a little impatient: "Are you mistaken, that fairy mountain is not at the bottom of the sea at all? He was about to step forward to pat Qin Guan's knee, but before he could touch Qin Guan, he was stopped by Qin Guan with a voice: "Elder Shu, go and let Elder Liao come out with Senior Brother Helian! I have found the location of Xianshan!" Shu Tong was stunned for a moment, and then did not dare to delay, and immediately rushed into the cabin, shouting for Liao Xingchen to take Helian Jun out to answer. Even the range of sound transmission under the water has been restricted, and the range of sound transmission that the monks in the foundation building period can reach up to 500 zhang has been reduced to only a dozen zhang, so it is no wonder that Shu Tong needs to come in personally to convey the message.

When Liao Xingchen heard Shutong's news, he hurriedly asked Min Hui and Luo Nan to bear the shield they had put up on their side, and took He Lianjun's collar, dragged He Lianjun out, and rushed to Qin Guan's side with a roar. Qin Guan struggled to separate a little spiritual power and explained to him: "Elder Liao, Senior Brother Helian, look, is there a stone tablet under my feet? Yes, it is the one that is covered by sand! When I was looking around with Elder Shu Tong just now, I inadvertently touched it with my spiritual sense, and I was absorbed by this stone tablet with a lot of spiritual power. It's inconvenient for me to move now, otherwise this mountain protection array will be opened, and if a little breath is revealed, this place should be discovered by others. Please hurry up and set up the magic circle, I can hold on for a while!"

Hearing Qin Guan's explanation, Liao Xingchen and He Lianjun didn't dare to slack off, after all, it was the place of survival that all of them cared about, and they didn't dare to slack off in the slightest, so they hurriedly took out the Qiankun bag in their arms. Liao Xingchen, as a Jindan monk who has practiced for hundreds of years, moves much faster than a young man like He Lianjun for decades, and can also share a lot of water pressure for He Lianjun when arranging the formation.

The two of them first placed the pre-designed center of the magic circle here on the stone tablet, because they knew that the pressure in the water was extremely high, in order to save effort, so in the process of descending, Liao Xingchen was distracted and refined a lot of array disks. The role of these arrays in defense and attack is not at all, only the basic patterns are engraved, which can be regarded as saving a lot of time for their underwater operations.

The two of them circled around Qin Guan together, Qin Guan was a little familiar with the magic circle, and he didn't understand the behavior of the two, but he knew that he was about to be unable to hold on, because the speed of absorbing spiritual power from the stone tablet under his feet slowed down, and he thought that he was about to finish absorbing it. Qin Guan didn't dare to make a rash noise to disturb the action of the two of them arranging the formation, for fear that if something went wrong in the formation arranged by the two, it would be more than worth the loss.

Time passed minute by minute, Qin Guan felt that the stone tablet under his feet was about to stop asking for spiritual power, and his heart was in his throat, worried that Liao Xingchen's magic circle had not yet been arranged, and the stone tablet took the first step to open the mountain protection array of the Immortal Mountain. Before he could press his mind and remind Liao Xingchen and the two of them, Liao Xingchen and He Lianjun took the first step to speak: "It's done!"

Hearing this, Qin Guan breathed a sigh of relief, and his control over his body dropped by one layer, and his feet suddenly became weak, and he was about to sit on the bottom of the sea. As soon as he shook his body, Qin Guan secretly said, "It's not good!" Before he could come back to his senses and stabilize his body, a dazzling light filled his eyes, and it was so bright that people couldn't help but close their eyes.
