The demons pressed together, spinning, and the monsters laughed and gathered in the middle.

Ye Zhiqiu suddenly felt a huge pressure, and he couldn't help himself, and retreated towards the demon pool.

Liu Xue was still chasing after Kungua, shouting: "Zhiqiu must resist it, you can't fall down!" ”

"But...... I really can't stand it! Ye Zhiqiu shouted, and his steps retreated, and he had already retreated to the edge of the Demon Transformation Pool.

"Xuantian Wuji, open!" Liu Xue shouted, and used all her strength to urge the power of the Wuji Fu to continue to cut the kun hexagram.

But those alien gossip were all runes composed of floating qi, which were cut by the Wuji rune, and quickly took shape, leaving Liu Xue with no place to focus.

Ye Zhiqiu had been forced to the edge of the Demon Transformation Pool at this moment, struggling to support himself, and his body was swaying.

The corpse demon suddenly appeared, appeared from the demon spirit team, and waved his hand to shoot out a string of fine lights: "Go down, Ye Zhiqiu!" ”

Those bright lights flew in, and quickly turned into white figures, carrying a magical power, like a huge wave at the head of the tide.

Ye Zhiqiu finally couldn't stand it, stumbled backwards, and fell towards the bottomless demon pool!

Liu Xue was taken aback, then chased after Ye Zhiqiu, jumped towards the demon pool, and shouted: "Six return to Xuantian, flying talisman hits the star, Xuantian Wuji, open!" ”

It's really a flash of inspiration, Liu Xue herself doesn't know why she thinks of this spell when she is in a hurry!

The Wuji Fu moved as he wished, and magnified with a bang, bursting out with a dazzling yellow light.

The black qi in the demon pool was all dispersed and sprayed onto the underground palace.

However, Ye Zhiqiu and Liu Xue also saw a black stream of water rushing towards them.

"Zhiqiu!" Liu Xue stretched out her hand and grabbed Ye Zhiqiu's arm.

"Xue'er, there's black water ahead, I don't know what it is!" Ye Zhiqiu backhanded, hugged Liu Xue's waist, and at the same time urged the Chiyuan Sword to open the way forward.

"Whatever it is, we can't get out of it, forward." Liu Xue gritted her teeth, and the Wuji Fu shot towards the black water sprayed from the bottom of the pool.

It was dark in front of him, and Ye Zhiqiu and Liu Xue were swallowed by the black water at the same time.

Fortunately, the Wuji Fu is powerful, forcing Heishui to not come forward, and Ye Zhiqiu and Liu Xue also have a relatively safe space.

Under the protection of Wuji Fu, Ye Zhiqiu and Liu Xue hugged each other and slowly descended.

It seems to be in a channel, slowly descending.

Ye Zhiqiu was about to speak, but he found that his eyes lit up slightly, and the black water around him was gone, and it was replaced by clear water.

And the space around him also suddenly became larger, as if falling into an underground river from a vertical passage.

But the undercurrent around him was turbulent, wrapped in Ye Zhiqiu and Liu Xue, and spun away.

"Zhiqiu, stay in shape, you can't follow the waves." Liu Xue shouted.

Ye Zhiqiu hurriedly calmed down, took root with his feet, and stood at the bottom of the water.

Liu Xue's feet also stepped on the underwater ground, looked left and right, frowned, and said: "It turns out that under this mass grave, there is still an underground river......

"The area is very large, there is no edge, it doesn't look like an underground river, it looks like an underground lake...... Ye Zhiqiu also looked around, and said: "Xue'er, we fell into the evolution of the magic pool, and then fell into the underground water flow, could it be that the transformation of the magic pool, there is also a teleportation effect?" ”

"The demonic energy in the Demon Transformation Pool should have been completely dispelled by my Wuji Talisman. I think the magic pool is broken, so that's why we fell down. Liu Xue said.

"Is the Demon Pool broken? But the corpse demon is still on it, will he chase it down, or deal with Lan Guoxiong and his wife on it? Ye Zhiqiu asked again.

Liu Xue smiled slightly and said:

"You forgot, the operation of the Demon Array is entirely based on the demonic energy of the Demon Transformation Pool. The demon pool has been broken, what other tricks can the corpse demons do? Whether he came to chase and kill us, or to deal with Lan Guoxiong and the others, it was a dead end. Without the blessing of the Demon Transformation Array, the corpse demons and those low-level demon spirits did not have much to do. ”

Ye Zhiqiu was relieved at this time, and nodded again and again.

Liu Xue took Ye Zhiqiu's hand, walked slowly underwater, and continued to check.

Ye Zhiqiu looked back and said, "Let's go back and find the place where we fell, maybe we can go back the same way." ”

"Don't worry, this underground water basin and the demon pool above, maybe it has something to do with it, let's find out." Liu Xue said.

Ye Zhiqiu nodded and checked with Liu Xue.

Anyway, it's safer at the moment, so there's no need to rush out.

It was also pitch black underwater, and although there was a faint glow from the Wuji Fu, it was not far away.

Ye Zhiqiu and the others were searching, but suddenly they heard a rumbling sound coming from the right, just like a train!

At the same time, you can feel that outside the water space, the water flow is impacted and turbulent.

"It's so strange, it's like the sound of a train......" Liu Xue frowned and listened to it.

"Underwater trains?" Ye Zhiqiu suddenly thought of the 'Dragon Horse Coffin' that his father-in-law, Liu Zhengliang, had studied before.

When he was in doubt, in the water a few feet ahead, a black shadow swept by, like a locomotive speeding away!

"Chase it and take a look!" Ye Zhiqiu hurriedly stepped forward to see what was going on.

But the underwater monster was so fast that it had already run away, and the rumbling sound was far away.

When she came to the place where the monster passed, Liu Xue looked down and shouted: "Rails, there are rails underground!" ”

"Ah, is it really an underwater train?" Ye Zhiqiu was stunned.

On the ground underwater, there are indeed metal tracks.

But not railroad tracks, but bronze tracks.

The direction of the track shows an arc trend. The surface of the track, the friction is shiny.

When you rub it by hand, you can feel the smoothness, as if it has been polished by a machine.

It is clear that this track has been in use all along, and the smoothness and brightness on it is caused by the constant rolling of the wheels.

Compared with the modern rails, the bronze tracks in front of you appear to be slightly smaller and slightly smaller in scale.

"It's unbelievable, there are railroad tracks and vehicles passing underwater!" Ye Zhiqiu was surprised, looked at the direction of the extension of the rails, and said, "Xue'er, let's follow the rails and see where this railway leads." ”

Liu Xue was more careful, measured the width of the rails, and said:

After Qin Shi Huang unified China, he stipulated that the car was written on the same track, and the axle length was unified to six feet. One foot in the Qin Dynasty is equivalent to 23 centimeters today, and six feet is equivalent to 1.38 meters today...... This track, with a width of only one meter two, seems to have been made before the Qin Dynasty, and it is probably thousands of years old. ”

Underwater trains, thousands of years old railroad tracks, it's unbelievable!

But all this is really in front of us, and people have to believe it.

Ye Zhiqiu nodded: "If we catch up with that locomotive, we may be able to uncover the mystery." ”

Liu Xue used the Wuji Charm to leave a mark on the rails, and then together with Ye Zhiqiu, she followed the rails and tracked in the direction of the locomotive. (3rd Update)
