Two days later.

The treasure ship of the Heavenly Medicine Sect stopped steadily above the Black Dragon Mountain in Lin City.

Lin Yi'an walked out of the luxurious cabin, and this morning, he had fused all the energy of Dong Yemao and the others.

And through comprehension again and again, his cultivation has been continuously improved, and now his strength can be said to be at the peak of the eleventh layer of quenching gods.

Calling this level above the peak of the ten layers of quenching gods the eleventh layer of quenching gods, Lin Yi'an also thinks it is quite appropriate.

Except for the incomparably terrifying Heavenly Tribulation when he just stepped into the early stage of the Eleventh Layer of Quenching God, he broke through to the middle, late and peak of the Eleventh Layer of Quenching God in the future, and there was no more Heavenly Tribulation.

And the Quartet Emperor Flame and the Nine Shades Blue Flame have not yet absorbed the Immortal Realm flint in the Incineration Furnace, after all, there are too many Immortal Realm flints in the Incineration Furnace, too many, and this kind of pure Immortal Realm Flint is enough for the Four Directions Emperor Flame and the Nine Shades Blue Flame to grow up a little, so they need a little time to absorb.

After breaking through to the peak of the eleventh layer of the Quenching God today, Lin Yi'an and the others returned to Lin City on the treasure ship of the Heavenly Medicine Sect.

Having just broken through to the peak of the eleventh layer of Quenching God, Lin Yi'an has been stable and understanding in the cabin, after all, he began to break through from the peak of the ninth layer of Quenching God to the peak of the eleventh layer of Quenching God.

Among them, the tenth layer of quenching gods and the eleventh layer of quenching gods are something that Lin Yi'an has not experienced in the ancient world, and this time he has stepped into two levels that he has not experienced before, it is necessary to calm down and stop and be steady.

When Lin Yi'an broke through at the gate of the Xu Family Manor in the Imperial City before, Liu Qicang and Qiao Dongce asked the sect leader Cheng Mingsong to take the rest of the Heavenly Medicine Sect back first, while they stayed behind to personally help Lin Yi'an control the treasure ship.

This time, Xu Huifang, Wu Xingliang and the others all came to Lin City together, Lin Yi'an planned to arrange all of them in Black Dragon Mountain for the time being, and he was going to go to the bottom of the sea where the Xuanyin Holy Beast had discovered the mysterious black box before.

Now for Lin Yi'an, the most important thing is to find a way to return to the ancient world.

When he walked out of the cabin, Liu Qicang, Qiao Dongce and the others were all standing outside waiting.

After coming up to the treasure ship, he entered a state of stability and comprehension, and Lin Yi'an didn't have time to ask Liu Qicang and Qiao Dongce.

At this time, his gaze was fixed on the two old men, and he didn't rush down from the treasure ship in mid-air, and asked, "Do you know the origin of the earth's cultivation inheritance?"

The reason for asking this question may be to find a clue to return to the ancient world from the origin of the earth's cultivation.

Hear the words.

After Liu Qicang and Qiao Dongce were slightly stunned, they fell into a short period of thought.

A moment later.

Liu Qicang said respectfully: "Master, I'm afraid no one can answer you about the origin of the earth's cultivation, but there are various legends. ”

Some legends describe that the cultivation of the earth was explored by the earthlings themselves, and some legends say that in a very distant time, a number of meteorites from outside the sky fell, and various cultivation techniques were recorded on this meteorite, and after being discovered by the earthlings, the road of cultivating the truth of the earth was opened. ”

"There are many such legends, but one of the most recorded legends in ancient books is that the earth's cultivation inheritance comes from other planes, and it is said that a great man who has the means to reach the sky came to the earth in the distant past, and on a whim, left a cultivation inheritance on the earth. ”

Lin Yi'an couldn't help but nod slightly, he also agreed with the last statement, and continued: "At the beginning, all of your sects thousands of years ago sealed themselves, is this sealing formation called the Tianyuan Wuji Array?"

Thousands of years ago, the major sects reappeared, the source qi between heaven and earth was constantly recovering, and when a vision appeared in the sky.

Lin Yi'an was almost certain that this was the Tian Yuan Infinite Array that had been lost in the Ancient World.

Questions for Lin Yi'an.

Liu Qicang and Qiao Dongce didn't dare to slack off at all, this time Qiao Dongce answered first: "Master, thousands of years ago, the major sects found a prophecy stone tablet, which described that the era of cultivation would usher in the end of the world, and at that time, many people were all about to step into cultivation, causing the source qi between heaven and earth to become thinner and thinner. ”

"The prophecy tablet says that in less than 500 years, the earth's source qi will be completely gone. ”

"The only way to rescue is a formation recorded on the stele, and no one can understand this formation, according to the stele, this formation is called the Tianyuan Wuji Array. ”

After a slight pause, he continued: "Fortunately, as long as you follow the step-by-step arrangement on the stone tablet, you can arrange the Tianyuan Infinite Array. ”

"It is said that at that time, the major sects exhausted everything before this formation was really arranged, and at that time, most of the source qi between heaven and earth was also divided by the major sects, leaving only a small part of the source qi in the world. ”

"It is recorded in many ancient books that at that time, not only we in the East, but also many in the West were involved, and the West also had a lot of inheritance, and they also needed the source qi between heaven and earth. ”

"The prophecy stone tablet describes that the Tian Yuan Infinite Array can restore the source qi of the entire earth, and once the entire formation is broken on its own, then the source qi of the earth will return to its former peak, and there will be no more depletion in thousands of years. ”

And the prophecy stone tablet, the moment the Tian Yuan Infinite Array was arranged, it immediately shattered into powder in the air, and the Tian Yuan Infinite Array was lost on the earth. ”

Listening to Qiao Dongce's slow words, Lin Yi'an frowned tightly, he didn't hear much useful information, if the prophecy stele still exists, then maybe he can find some clues, he asked again: "Do you know the general direction where the stele appeared?"

Liu Qicang said: "Master, you wait here for a while. ”

After saying that, he entered one of the rooms of the treasure ship, and after a while, he quickly swept out again, holding an old ancient book in his hand, and said, "Master, on this treasure ship, there happen to be copies of many ancient books in our Heavenly Medicine Sect. ”

"This book was left by the ancestor of our Heavenly Medicine Sect, and the ancestor also went to the place where the prophecy stone tablet appeared, and he happened to have nothing to do and recorded the approximate location. ”

Liu Qicang turned a specific page of this ancient book upside down, only to see that on this page was a vague map, which could only roughly identify a certain direction.

After Lin Yi'an took the ancient book, he used this vague map to roughly calculate, and his brows furrowed suddenly: "There is such a coincidence in the world?"

Because of his relationship with the master and servant of the Xuan Nether Holy Beast, he already knew the approximate location of the mysterious black box in the sea area.

But after using this vague map to calculate, in the distant past, the place where the prophecy stone tablet appeared was actually the same and similar location as the mysterious black box!

Could there be such a coincidence in this world? Could it be that there is some kind of connection between the former prophetic stele and this mysterious black box?

From this point of view, perhaps there are really a lot of secrets at the bottom of the sea where the mysterious black box was found by the Xuan Netherworld Holy Beast, and there may be clues to leave the earth.
