At the bottom of the dark underground lake of 10,000 meters underground, Jing Wudao withstood the turbulent undercurrent and the high pressure of 10,000 meters of water depth, and with the assistance of the elves' exploration waves, he was constantly searching for energy fluctuations.

As long as it is a treasure, there will be a faint and faint energy wave emitted around, and the elves also rely on this wave they emit to discover their existence.

Jing Wudao was wandering in the underground lake, like a happy little fish.

The bottom of the lake is overgrown with all kinds of aquatic plants in their original appearance, and all kinds of aquatic creatures that are rare in the outside world, which is a new world isolated from the world.

The level of some aquatic creatures had even reached the level of sub-holy beasts, but under the powerful aura emanating from Jing Wudao, they were so frightened that they fled.

Jing Wudao searched the entire underground lake that was more than ten kilometers long, and found nothing.

"Elf, don't you really feel any energy fluctuations?" Jing Wudao asked.

The entire Tianjing Canyon was almost searched by him in three days, and there was no trace of any super ancient ruins, and he finally found a hidden underground lake, but unfortunately there was still nothing found, Jing Wudao felt a little helpless in his heart.

Moreover, the current number of heavenly crystals was not enough for him to advance to the level of the inner world, so this enthusiastic treasure hunt did not achieve his goal.

"Master, the elf searched carefully over and over again, but there really wasn't the slightest energy fluctuation, it seems that the shuttle crystal appeared by accident. The elf also said angrily.

"Huh~ What's that?"

At this moment, Jing Wudao, who was looking around, found a huge bluestone in the dense water and grass.

Lifting the water weed, Jing Wudao also saw its face clearly, a piece of precious green rock ten meters long, six meters wide, and one meter high used to cut the city wall, on which countless mysterious rune patterns were depicted.

Qinggang rock, extremely hard, contains magical energy, and only the imperial palaces of the three ninth-level civilization empires are willing to use this material to cut the wall.

This is also the reason for the material richness of the Chaos Continent, and in the universe, I am afraid that even a force like the Heavenly Wolf Clan cannot afford to cut the wall with Qinggang Rock.

"This is a brick that has been artificially processed, and it shows signs of being damaged by force. Jing Wudao's heart was extremely excited, "There are artificially processed bricks of the city wall, which means that there was once a city here, is it a city in the super ancient period?"

It's too secretive, and it's under an underground lake that's 10,000 meters deep, and it's almost certain that it's a brick from the ultra-ancient period.

Moreover, this mysterious rune pattern that even elves can't understand also indirectly proves that it is likely to come from the legendary ultra-ancient, that era when the martial arts civilization was highly developed and there were countless gods and spirits.

"Look at the bricks of this Qinggang rock city, there are potholes and cracks everywhere, it seems that it has experienced some major damage, is it related to the destruction of this city?"

Qinggang rock is no less solid than a demigod armor, and it has a magical ability to resist the destruction of the outside world, but since it has been destroyed to this extent, it can be seen how big the disaster was at the beginning.

The idea of the ruins of the city in the ultra-ancient period began to take root in Jing Wudao's mind, and he was crazy to find it.

If a city is suddenly destroyed, there must be a lot of treasures left in its original place.

Those Celestial Crystals scattered in the outside world. Ultra-ancient items may be the best proof of this.

Since the bricks of the ultra-ancient city have been found here, the comparison is not far away.

Without the slightest hesitation, Jing Wudao plunged headlong into the ground and began to dive underground.

100 meters.

1000 meters.

10000 meters.

......

Jing Wudao kept searching and diving, until he reached a place about 15,000 meters underground.

"Boom!"

Jing Wudao, who had just dived to this position underground, was directly bounced up forty or fifty meters by a powerful energy before slowing down his body.

"What's going on, such a strong force, I was directly slightly injured. ”

Jing Wudao broke out in a cold sweat at this time, and his whole person was in shock, he didn't expect that something could stop his dive, and he was injured.

"Master, I've investigated, it's a seal prohibition, you just touched the prohibition, and you were rebounded by its power. The elf explained at this point.

"This prohibition can hurt me, it's not ordinary. Jing Wudao was surprised.

With his current strength, he can still be hurt by the forbidden power, which is incredible.

At the same time, his mind was also lively, no fool would arrange a ban here for no reason, obviously there is something very important behind the ban, maybe it is the ruins of the super ancient city he is looking for.

"Master, you mobilize the teleportation power of the shuttle crystal to me, and I will probe the wave through this prohibition to investigate the situation inside and see if there is any danger. ”

"Hmm. Jing Wudao then mixed the energy of the shuttle crystal into the elf's detection wave.

"It's terrifying, inside the master is an underground space that has been banned and sealed, containing such terrifying energy, and I can't specifically detect the situation inside, that is, because this prohibition seals the energy inside, so that it can't be dissipated, this should be the location of the super ancient city. ”

"There is probably a mortal danger inside, master, do you need to go in after you think clearly?"

"Relying on the ability to shuttle crystals, you should be able to enter directly without breaking the forbidden energy. The elf reminded with a reluctant tone.

"If you don't enter the tiger's den, you can get the tiger. After years of cultivation, Jing Wudao had already understood this truth.

The path of cultivation is inherently full of dangers.

Jing Wudao urged the teleportation power of the shuttle crystal, and passed through the powerful prohibition of the seal without the slightest hindrance.

Suddenly, a huge dark and cold underground space appeared in front of Jing Wudao's eyes.

Jing Wudao's eyes lit up, and he was extremely excited, this was really a ruins of a city in the ancient period, the basic outline of the city was still there, and there were huge cylindrical stone pillars, brick walls, and stone arches scattered everywhere with hundreds of tons...... and other items for the construction of castles.

These were potholes, cracks, and even broken into several pieces, which collapsed and were half-hidden underground.

The ruins and ruins are full of ancient atmosphere that has been immersed in hundreds of millions of years.

For a long time, most of the belongings were submerged under the land.

However, to Jing Wudao's surprise, the scale of this city was not large, it was about the same as the Daoless City during the period of the second-level civilization empire.

"The city of the super ancient period can lay down the powerful strength that can make me injured and forbidden, and I have made a fortune!" Jing Wudao exclaimed excitedly.
