"Hurry up!!Hurry up!!" Tang Yan and the others sprinted at the bottom of the river at full speed, facing the rushing river upstream.

In different directions, Li Baiying and the others, Allison's troops, and Zhao Huan's troops, who joined later, all rushed towards the bottom of the lake.

"I'll go first! You guys pay attention to safety!" Tang Yan suddenly unfolded eight thunder seals, turning into eight chaotic golden thunderbolts, which violently expanded more than five hundred meters.

Affected by the flow and space at the bottom of the river, the eight thunder seals failed to achieve the amazing effect of a kilometer, but the distance of five hundred meters was still extremely good.

"It's so fierce! he can do more things than me!" Nian Youyu was startled.

"Keep up!!" Xu Yan vibrated a pair of dark bone wings behind him, and with a sharp slam, he tore through the water like a sharp blade, and chased after him at great speed.

Tang Yan cast the eight-phase thunder seal one after another, regardless of the loss, and rushed into the lake area in just ten breaths. Without stopping, he dived violently and went straight to the bottom of the lake. The area of the lake is huge, but the depth is even more terrifying, and you can never find a trace of it all the way down.

The bottom of the lake is becoming more and more peaceful...... Dark......

Moreover, the water pressure at the bottom of the lake continued to surge, and it was pressurized in a very abnormal and exaggerated way!

When Tang Yan dived more than 1,000 meters into the tunnel, the expansion distance of each Thunder Mark was shortened to fifty meters, which was still the limit of his full exertion.

"Good girl, the pressure is too much, isn't it?" Tang Yan paused for a moment, calmed down his heavy breathing, and swallowed a handful of spiritual source liquid to replenish his consumption. The terrifying water pressure has skyrocketed to tens of thousands of catties, squeezing in all directions, as if to crush anything into powder, and it is absolutely difficult for the demon venerable to even move.

The bottom of the lake is deep, the water pressure is too huge, the lake water is a little viscous, and the environment is as black as ink, and there is a dead silence.

The diffusion of sound and energy is severely restricted.

Tang Yan stimulated Sen Luo's eyes and looked carefully towards the bottom of the lake. Sen Luo's vision range was also restricted, but after staring carefully for a long time, he faintly found some bright light at the bottom of the lake, and there were wonderful energy fluctuations, like gentle ripples spreading from the bottom of the lake to the surface of the lake.

"I hope to surprise me. Tang Yan took a deep breath and dived at full speed.

I don't know how long it took, and I don't know how far I went, but the light in my vision became brighter and clearer.

Finally, Tang Yan landed at the bottom of the lake, where the river was undulating and chaotic, like a rugged mountain outside. On one of the raised stone mountains, a very hideous sinuous crack appeared, about six or seven meters wide and thirty or forty meters long.

The colorful glow of the sun shines through the cracks.

It's like the eyes of hell open, and it's terrifying.

Tang Yan looked around, found no other traces, he should have arrived first, observed a little, and rushed over vigilantly.

As soon as I entered the cave, the scene inside suddenly opened up.

There is a cave inside the stone mountain, which looks like a huge palace carved out. It is vast and magnificent, up to twenty or thirty meters, and the width is the size of a football field, and there is an ancient and vast atmosphere everywhere.

Hundreds of night pearls dot the steep stone walls, illuminating the cave as if it were daytime.

It may be that the cave was hollow before, but the sudden crack caused the water to pour into the bottom of the lake, causing the cave to be filled with water, and all the ornaments and objects were floating in a messy manner.

Tang Yan stared at the stone cave vigilantly, and at this time, an iron sword floated in front of him with the flow of water, it was already rusty, twisted and tattered under the huge pressure of the bottom of the lake.

It may have once been a sword, but it has been depleted by the erosion of time.

A stone bench fluttered with the ebb and flow of the water, already decaying, full of cracks, and constantly clicking under the pressure of the water, and in a few moments it shattered, turning into a mess of small stones floating in the water.

Tang Yan held his breath, used his spiritual power to keep his body running, and quickly dived and landed on the ground of the stone cave, surrounded by a dazzling array of objects, but they were messy, and they were all broken under the action of water pressure.

As you can see, they are very, very old, and the old ones have become rotten waste products, and they have little use.

"Who built a stone cave at the bottom of the lake? Is this a palace?" Tang Yan was vigilant and curious, and even more surprised, carrying the water pressure and walking forward slowly.

At this moment, a violent clicking sound sounded, and the crack above the stone cave was expanding, and the broken stones were floating silently.

Finally......

In the middle of the dilapidated stone cave, Tang Yan stopped and stopped, his face stunned.

In front of him appeared an ancient and dilapidated stone platform, like the kind of sacrificial high platform, around the rise of eighteen stone pillars, wrapped with black chains, compared to the decay of other objects, although the stone pillars are full of cracks, but still proudly towering, the chains once wrapped around some beast, now only messy bones, scattered with the impact of the water and scattered in the water.

Above the stone platform, there is an ancient stone tomb!

It is only half a meter tall and less than two meters in diameter, in the shape of a rudimentary dome.

"Whose tomb is it?!I have a fate with the tomb in my life?" Tang Yan laughed at himself and was surprised, and quickly rushed to the stone platform, but the tomb was smooth and flat, without any marks and records, only a bare tombstone.

Whose grave is buried?

Whose graveyard did it?

Tang Yan looked around the entire stone cave, although it was founded by a chiseled mountain, but judging from the scattered objects, they were all very delicate things. The ancient stone cave can be seen in the original outline and neat arrangement.

"Senior, offended. This world is in chaos, and the younger generation needs something to save their lives. You don't want what you've learned all your life to be buried with you, it's time to find a successor. Tang Yan bowed three times in front of the grave to show respect, and then took out the black coffin and secretly slammed it with all his might.

"Stop!!" a sharp roar suddenly came from behind.

Tang Yan didn't pay attention to it at all, and the black coffin still crashed down. Qiang. Sparks splashed, loud noises roared, and the whole cave trembled. Click, click, crack, crack, rapid expansion, but not the tomb broken, but the stone cave was shaken out of two new cracks.

Hey??

Tang Yan was stunned, the black coffin couldn't be broken?

The tomb was neatly worked, sitting firmly on the stone platform, without any traces of breakage, but it shook Tang Yan's handwriting with a sour tingling pain.

"I'll tell you to stop!!Is this the place for you to be presumptuous!" Allison's huge body squeezed into the stone cave, entrenched in deterrence, and the two hands in front pulled out a dark blue bow and arrow, and the sharp arrow condensed by the water element force pointed at Tang Yan's forehead.

Murderous intent!!

"Is this your home? Why do you say stop?" Tang Yan smiled, shook his head, and suddenly raised his hand in the next moment, the scorching sun earth bow pointed at Alison, and the ghostly green fire swept up from his whole body, quickly converging on the bow and arrow, turning into an equally strong sharp arrow, pointing at Alison's forehead.

In the bright stone cave, under the heavy pressure of the water, the green fire is still infinitely arrogant, gathering might.

"This is the River District, this is the world of my Naga clan, the water element force suppresses a qiē spiritual power, and the water overcomes fire, you are not my opponent. Alison snorted, and the other six fingered arms were raised one after another, dancing different weapons.

Two blue javelins, two blue long swords, and two blue long sticks, all steaming with surging water element power, made its momentum soar. And the edge of the blue javelin also pointed at Tang Yan, with the sharp arrow in his hand.

"Really?" Tang Yan smiled, before the words fell, the smile turned fierce, and the scorching sun earth bow that he tried to pull away suddenly released, and the stone platform under his feet shook violently, and the whole person shot up, and the black coffin blasted up.

The sharp arrow tore through the tide of water and went straight to Allison! And along the way, the green arrow burned the water so quickly that it formed a hollow, and the water in all directions was immediately replenished, and suddenly formed a slender and extremely fast whirlpool, which extended all the way with the sharp arrow.

And Tang Yan was faster, the momentum was wilder, and he rotated the black coffin, and bombarded it with the momentum of Mount Tai.

"Something that can't help yourself!" The sharp arrows in Alison's hands were released at the same time, and the two javelins were violently projected, and at the same time, the snake's tail was agitated, like a spring compressed to the extreme, released in an instant, killing Tang Yan.

Rockets and water arrows collide halfway!

Boom! Violent muffled sound, instant solidification!

The space at the point of impact bulged up like a balloon, and the two energies and colors merged instantly, and then ...... The violent explosion was accompanied by an earth-shattering loud sound, exploding in the center of the cave, forming a whirlpool-like twisted zone that swept over more than 100 meters.

Tang Yan and Allison in the impact were disturbed at the same time, and they were violently bounced away by the violent energy, and they tumbled out in different directions.

Even Alison's transmissive javelin was affected by the energy blast and forcibly deflected its bearings, blasting into the cave in the distance. With a violent loud bang, the cave more than 100 meters later was violently blasted out of a huge hole, and the javelin momentum did not stop, and disappeared into the dark bottom of the lake in an instant.

The strength is terrible!

Tang Yan and Alison retreated to the edge of the stone cave at the same time, both showing shocked faces.
