Looking at the bottomless whirlpool under the hull, Chen Hanyu was in a dilemma, he was worried that the ship would be swept into the whirlpool, and he didn't know why their spiritual power didn't seem to have any effect.

"If I talk about flying, I'm afraid I'm the only one who can leave, but the other disciples can't do it. Chen Hanyu didn't dare to put down the assault boat at all, at this time, he still pinned his hopes on Zhao Liang's skills.

Zhao Liang hit the rudder to the left, but the hull did not shift, in his words, the conditions of attraction were too great, and their ship was firmly sucked and couldn't shake it off.

"Don't panic, everyone, I'll try!" said Tempest, rolling up his sleeves and jumping into the water.

Chen Hanyu didn't have time to hold him at all, this wind was too reckless, let alone him, even if it was such a big wave, ten ships connected together might not be able to move.

But in the next second, a miraculous thing happened, the wind in the water did not seem to be affected, and his figure came and went freely around the whirlpool.

"Brother Yu, there seems to be something down here!" the wind poked its head out of the water and roared loudly.

"Go down and take a look!" Chen Hanyu changed into diving equipment, and he also specially carried a sufficient oxygen cylinder.

Before launching the water, he specially instructed Zhao Liang to turn off all the engines and power of the boat, and the boat would not float anywhere for a while.

The moment he just entered the water, Chen Hanyu felt that his body was wrapped in a burst of cold air, because his body did not adapt quickly because he came into contact with the cold water surface all of a sudden.

With the release of true qi, he can barely dive the whole person, and the underwater scenery is indeed as the wind said, although it is very turbid, but you can vaguely see that there are many caves in it.

"Storm, let the branch masters of the water come down, there may be a situation here!" Chen Hanyu specially instructed Ye Zhi to stay on it and take care of it, in case his own people were in danger.

They used the most labor-saving method to dive in, which was to slowly probe down the edge of the whirlpool, so that they would not be squeezed by the suction of the whirlpool, nor would they be unable to dive due to resistance.

"Don't you need protective gear?" Chen Hanyu asked as he looked at the wind beside him suspiciously, he seemed to be an iron lung, and he didn't need to breathe for such a long time underwater.

Tempest smirked, he told Chen Hanyu that he was just born with a good water nature, which can be regarded as a unique talent, and he is a king-like existence in the water.

Seeing that the wind could breathe freely underwater, Chen Hanyu didn't say anything, and they continued to swim towards the cave.

"You have to be careful, there's a lot of pressure here, try to keep your body stretched, or you'll be overwhelmed!" said the wind and drilled hard, landing steadily on top of the cave.

Chen Hanyu could feel the change in the pressure in the water, after all, how could such a large whirlpool above be as calm as the wind and waves, and it took him five minutes to slowly swim to the door of the cave.

Then the branch masters of the outer gate followed one by one, and their speed was not slow, and the protection of true qi did not suffer much impact.

"This is a cave, and there is a lock!" Chen Hanyu smiled and pulled the iron lock on the door, this iron lock had long been rusted because of its age and the fact that it had been soaked in water, and he couldn't tear it open for a while.

"I guess I'm going to use iron tongs, the effect of spiritual power here is almost canceled out!" Tempest shook his head helplessly, and he jumped up with force to poke his entire body out of the water.

This time he was followed down by a disciple of the Black Tiger Hall, who was still holding a huge iron tong in his hand.

Sure enough, after using the iron tongs, the lock fell down at once, and everyone pushed open the door and walked in.

Upon entering the cave, they realized that the place was very dry, and that there was no water running in, except for a few puddles of water at the entrance of the cave.

"It's weird, don't you have anything in here, there is so much water outside, and such a big wave can't get in?"

Tang Feng asked puzzled, he had never seen such an unbelievable thing.

"The reason is very simple, the dry temperature here means that there is a ventilated place, and it is not downstream, so the water can't come in!"

Chen Hanyu estimated that it should be convective air here, which is why it is so well preserved.

When the wind entered the door, he took the iron lock tied to the door, and he looked at it carefully for a long time before giving an approximate number.

"This iron rope is hundreds of years old, but it is an antique, and it can be worth a lot if it is sold for money!"

Indeed, no one can tell how many antiques there are here, but the longest river in the time period is here, and the civilizations derived from the surrounding river basins have indeed created a lot of glory.

The group continued to walk forward under the leadership of Chen Hanyu, and they could only rely on the faint spotlight to observe from the dim light at the beginning.

"Why don't we use spiritual power?" said a disciple who knocked out his spiritual power, and for a moment the entire cave was illuminated as bright as day.

Everyone saw what was going on in the cave, and it was supposed to be inhabited, and it wasn't for a short time, so to speak, for a long time.

Continuing to walk forward, Chen Hanyu found dozens of large and small caves, the same size as his position, these caves were large enough to accommodate two adult men walking side by side.

"Dare to love that there is still such a world under the water?" Chen Hanyu suddenly became interested, according to the news of Seven Inch, if the head of the Blood Knife Sect did not die, but lived here, then there was a chance to get the Blood Knife Spectrum.

After a long search along the cavern, they found no useful clues, as if there was nothing but traces of their previous life.

"I think I'd better go to the other side!" said Tempest, scurrying out like a fish, his speed not slowing down, but accelerating until he reached the other side.

But when he saw what was on the cave, he hurriedly beckoned everyone to go up.

"Brother Yu, what's wrong with this wind, waving at us is signaling us to go over?" Tang Feng looked at the wind on the opposite side in confusion, he didn't realize it for a while.

Chen Hanyu's face was not quite right when he looked at the wind, and with his gestures and body shape, it seemed that he was about to run.

"Quick, everyone, hurry up!" Chen Hanyu yelled, and he rushed out of the cave, and with the help of the sprint, he quickly changed his position in the water and swam up.

This time, the disciples of the Dao Alliance could see it clearly, and behind them, countless black air currents were rushing towards them.

"Damn it!" Tempest saw that their movements were being held back, and hurriedly stopped.
