Zhendong Great Plain, the vertical and horizontal are more than 5,000 miles, Huanghuang black soil, more than ninety percent are very flat, not even a hill.

However, there are two long and wide rivers, more than seven or eight boundless meadows and swamps, and more than a dozen small freshwater lakes.

In addition, there are three bottomless heavenly caves, black and rumbling, after a thousand meters, you can't see anything clearly, and no one dares to go down to visit the strong people below the transformation realm.

It is said that perhaps it is a hole poked out by the Gu Immortals, leading directly to the Immortal Cave in the core of the earth.

Qin Yu originally thought that the mysterious spirit cave that Ren Houtu said must be one of the three heavenly caves.

Unexpectedly, under the guidance of Ren Houtu, everyone flew directly into the extreme depths of the Great Plain of Zhendong.

Somewhere near the center of the plain, three thousand miles, there is a small lake that is no more than three miles long and wide, clear as a mirror, and the light can be seen.

Ren Houtu's three-winged flying batter circled around this ordinary small lake three or four times in a row, until Qin Yu's Huang Xiaoxiao and Sang Hong's sea beast flying carpet slowed down.

Qin Yu was surprised: "Brother Tu, what kind of spirit cave are you talking about, right here?" ”

Ren Houtu laughed: "Yes, the entrance to the Spirit Cave is at the bottom of this small lake." ”

Sang Hong's flying carpet stopped at the center of the lake, she held a silver mirror in her hand and looked at it carefully, and couldn't help but shake her head: "This lake is so deep, my cave water mirror can't see the bottom." ”

"Don't look at the narrowness of this lake, in fact, it is at least a thousand feet deep, and within a mile near the bottom of the lake, all that grows is a strange aquatic weed, which is good at isolating the detection device. Otherwise, this spiritual cave has already been dug for people, where can we wait to grab it? ”

Qin Yu and Sang Hong both nodded.

"But Brother Tu, don't you say it earlier, my crane is still young. It can not be entered into water. Qin Yu reached out and touched Huang Xiaoxiao's neck. Huang Xiaoxiao happily sucked the wind aura in his hand.

"Earlier?" Ren Houtu laughed, "I said earlier, brother, you must have thrown your brother away, and you sneaked here by yourself, hahaha!" ”

"Where, at least I'll talk to Brother Tu." Qin Yu snorted shamelessly, and he came into contact with it in the past two days. Ren Houtu's temperament is very temperamental to him.

Sang Hong looked at the two of them and laughed, just shaking his head.

"You two better come to my flying carpet, my flying carpet is covered with the skin of a black whale and contains the lungs of a white dolphin.

Qin Yu and Ren Houtu glanced at each other and nodded.

To go to the bottom of the lake. This aspect is the strength of Sang Hong, who was born in the sea country, but there is no need to argue.

……

At that moment, the two of them boarded Sang Hong's sea beast flying carpet and sat side by side behind Sang Hong.

When they sat down, Sang Hong was mobilized.

Originally, he drove a blanket car in the air, but immediately transformed into a tiger-headed giant shark with a hideous face and a length of more than ten meters.

Such a giant shark fell into the lake, almost occupying most of the lake.

Qin Yu and Ren Houtu sat in the belly of the giant shark, smooth and steady, without any feeling of bumps and shocks.

This shark submarine is kind of interesting.

Sang Hong immediately pointed with his hand. In front of the three of them, a wide silver mirror with a diameter of two meters appeared.

On the mirrored surface is a water feature outside the giant shark. Fish with tails roam freely, and occasionally larger, red-black fish surround them, curious about the huge kind.

"There's a lot of audacity here. If it is in the colorful sea on our side, this mature black gold tiger shark is the overlord beast in the sea, and within a thousand zhang, even the blue whale king and the squid emperor will be terrified. Looking at the shadow and fleeing, there are no demons who dare to approach. Sang Hong said in surprise.

"Sister Hong, I guess these red and black fish may be the little overlord level in this lake, and when I saw your incredibly big tiger shark, I suddenly came to kick the hall...... Provocation. You must come over and ask for an understanding, otherwise you won't be able to rule other small fish and shrimp in the future. ”

Qin Yu said a few words, and both of them laughed.

Ren Houtu said: "These red carp have been here for thousands of years, and they have never seen much of the world, so don't pay attention to it, just dive all the time." ”

While several people were talking and laughing, the tiger head giant shark sank straight all the way at an astonishing speed.

Three hundred zhang!

Five hundred zhang!

Eight hundred zhang!

When he arrived at 800 zhang, Ren Houtu took a closer look and suddenly said, "Turn left." ”

Sang Hong then steered the tiger shark boat to turn to the left, and even in such a deep lake with a lot of pressure, the movement was still quite easy.

Under the guidance of Ren Houtu, the giant boat gradually sailed into a ditch with deep mountains on both sides, and from time to time long aquatic plants floated over, and were hit by tiger sharks and flicked back.

"Stop! Turn right. Ren Houtu suddenly let out a low snort, and then, a smile appeared on his face.

"Fortunately, this entrance hasn't changed much, otherwise, I wouldn't have dared to recognize it."

Sang Hong controlled the giant boat and slowly turned to the direction that Ren Houtu said.

Qin Yu's eyes glowed with white light slightly, staring at the past, and sure enough, he saw a huge cave in front of him that was slightly darker than the color of the lake.

If it weren't for Ren Houtu's explanation in advance, and he had the ability to make a white room, in the depths of such a dark lake, it would be impossible for anyone to see this kind of cave that is several meters long.

"How did you find this cave?" Sang Hong slowly controlled the tiger shark and drove straight towards the entrance of the cave.

"I have a brother who is from the water tribe and is good at pearl picking, but he has not been in this business since following me. Ever since I had been given the errand of the beast messengers, I had often taken them on expeditions deep into the plains, and a few years earlier the brother had happened to pass by this little lake, and when he saw that it was very deep, he had dived to the bottom of the lake and discovered the cave by accident. ”

Although his voice was calm and unwavering, as usual, Qin Yu could hear that his words were ominous, as if he was hiding something.

"This big brother is so watery!" Sang Hong boasted.

"Alas, born in water, died in water!" Ren Houtu sighed, "My brother is too self-assured of water, he stayed under the water for a long time, and his lungs were unconsciously eroded by poisonous water. ”

Qin Yu and Sang Hong were suddenly silent.

"The waters around this cave were originally poisonous, but later I took a lot of effort and got the guidance of a master to plant some different aquatic plants to eliminate most of the hidden poison in the water." When Ren Houtu said this, the tiger shark suddenly shook slightly, as if there was some obstacle, he nodded, and looked at Sang Hong, "This is a simple magic circle that I asked the master to set up that year, which can stop the lake water from pouring in, and I didn't expect it to be damaged yet." Let's stop here, don't go too deep, lest you startle the lion. ”

With a soft whirring sound, the roof of the tiger shark submarine was wide open, but not a drop of lake water spilled into the cabin.

Qin Yu looked up and saw that the tiger shark boat had already entered the cave of the spirit cave, there were some strange energy fluctuations in front of it, and the water was getting shallower and shallower, and the tiger shark boat was floating on the water.

"Okay, we have entered the spirit cave, below, there may be a stone lion rushing out at any time!" Ren Houtu said lightly.

Qin Yu stood up from his seat, a shadow flashed, and He Hongchang appeared.

"Senior sister, the end has arrived!" (To be continued......)
