According to the records of these ancient books, the so-called primeval period, tens of millions of years ago, the spiritual power of the weather was much stronger than now, and even the division of the realm was different from now.

It is said that at that time, the human world here was still the same as the immortal world, and the immortal cultivation world was far more prosperous than now.

It is said that there were countless supernatural powers and secret techniques created in that era, and magic weapons and spiritual treasures emerged in an endless stream, and the competition for resources between monks was not as tense as it is now, and it could be said that there was harmony at that time.

But later, for some reason, the entire human world suddenly suffered a catastrophe, the passage was disconnected, countless powers fell, the weather was several times thinner than before, and the number of heavenly and earthly treasures also decreased sharply.

And at that time, the human world was discovered by the ancient demon race, and then caused a great war, which was extremely tragic, and the Dao system of the human race was also broken during that period of time, which lasted for hundreds of thousands of years.

Later, I don't know how many tens of thousands of years passed, and some human beings found some cultivation classics from some ancient ruins, and slowly cultivated and explored, and the human race regained its vitality and slowly developed to this realm.

For that legendary period, some classics are also vague, and there are different opinions, after all, the time is too long, and Han Yu only read some sporadic fragments in some ancient classics in the study. The number of these texts is the rarest.

"Could it be that the Tower of Babel is an antiquity handed down from the primeval era?" Han Yu's face was a little ugly.

The gray-clothed old man said with a straight face: "It's not an ancient power, but it's also a powerful man, it was he who got the remains of a tower from a secret mirror, and then transformed it." He is the Earthquake Sea Heavenly Monarch! The Earthquake Sea Heavenly Monarch sealed the treasures in the tower before going to the Immortal Realm. ”

"The opening location of the Tower of Babel is said to be in the Sea of Ten Thousand Evils. Before the Heavenly Monarch of the Earthquake Sea wanted to go to the Heavenly Realm, he shattered a magic weapon called the Key of Babel into hundreds of pieces, and only when the people of the future generations got this fragment could they enter the Tower of Babel, so as to obtain great benefits. It is said that there are also elixirs that can condense into primordial infants, powerful spiritual treasures, various long-extinct spiritual materials, etc., and there are still many benefits to be obtained. ”

"The fragment of the secret key...."Han Yu felt a little helpless in his heart, where did he go to find this thing that he had never heard of.

Now I can only hope for the news brought by Shopkeeper Ye and see if I can find some clues from there.

After getting the news, Han Yu returned to the study and began to search for ancient classics all over the mountains to see if there was any way to find some clues.

But then it was nothing.

Three days later, Han Yu got the news from the shopkeeper Ye, and he smiled bitterly, and this clue was broken.

It turned out that this family was not the original owner of the shell, but after several turnovers, it was taken by the ancestor of his family, and he wanted to advance to explore the mysteries in it.

But how difficult the road to the knot is!

There were many monks in the late stage of foundation building in this small family, and they all died in the thunderstorm. A few generations ago, there were not even monks in the late stage of foundation building, and the entire family relied on a monk in the middle stage of foundation building to maintain it.

The monk in the middle of the foundation building period was not heard from after a certain journey, and several surrounding forces turned their minds to the family. After all, they were once brilliant, and there were still a few good magic weapons in the family.

Although the qualifications of this small family heir are not good, but the ability to observe words and emotions is not small, he saw that several major families around him investigated again and again, and he took out all the things in the treasure house in advance on the eve of several families joining forces to strangle, and fled to Richeng with a roll.

He sold a few good magic artifact raw materials to Changyun Auction House, and handed over these ancestral shells and books to Shopkeeper Ye, who curryed favor with Han Yu and brought them over.

Shopkeeper Ye found the heir of the small family and bought those shells at a high price, but the heir told him that there were only a few in the family.

Han Yu couldn't do anything after knowing the news, but he finally had a clue, which was better than a black eye.

Han Yu didn't give up digging for clues for two months, but he still found nothing, so he could only give up helplessly.

Han Yu did not go to the study, but swallowed the pill in the cave and meditated to see if there was some loosening in the stagnant realm.

Since the follow-up exercises can't be found, let's find a way to break through the middle stage first, and then go to the Zhao clue slowly.

There are so many monks in the Tower of Babel, maybe the exercises inside are hidden in the secret place of a certain family, so wait for the opportunity with peace of mind.

On this day, Han Yu tried to break through the realm with a partial method, and suddenly looked stunned, and stood up after finishing his work, letting Shi Ling and them hide, and then walked towards the gate of the cave.

"Looking for brother, Master Shi, why do you have time to come to the Humble House this time?" Han Yu looked at the two acquaintances outside the cave mansion and immediately greeted him gently.

"I haven't been to Brother Han's cave for so long since I came to the island, so I came to see it this time. Master Zhao saw Han Yu open the door of the cave mansion and immediately greeted him gently.

"Please come in!" Han Yu said with a smile, inviting them into the cave mansion.

The old man in gray helped him a lot a while ago, although he still had no clue about the exercises, but the several monks he introduced exchanged feelings with each other, which also benefited Han Yu a lot, and the two of them had some friendship.

As for Shi Zhen, I heard that he was busy with a junior Yudan, and since the last time he said goodbye to Redfish Island, he hadn't seen him for a while.

Now seeing these two people, he is naturally a little happy in his heart.

The two entered the cave, Han Yu poured fragrant tea for them, and the three of them chatted about the upcoming ring match.

"Brother Han, this time I am an escort, and Brother Shi has something to tell you. The old man in gray smiled lightly and said a word, and then waved his hand.

"Oh, when Brother Shi just said it, Han listened to it. Han Yu said seriously.

Hearing this, Shi Zhen smiled bitterly and said slowly: "I just came back from outside, and I came to ask Brother Han for help." My junior's mentality of cultivating the exercises has been a little anxious during this period of time, which has led to the confusion of the exercises now, and the vitality has been greatly damaged. I would like to invite Brother Han and two other Daoists to go on a trip to the Sea of Fog and Heaven to find elixir in a cave. ”

"Through the sea of fog, Dongfu?" Han Yu heard this, and immediately wanted to refuse the thought in his mind.

He is too lazy to provoke what's wrong.

"Please also ask Brother Han to help!" Shi Zhen stood up and said earnestly towards Han Yu.

"Brother Han, this time I went to the Tongtian Fog Sea is the famous Shi Zhenren of the Nine Dragons Sea, I had the opportunity to go to the Tower of Tongtian once when I was in the Yudan, and there is a high probability that there will be fragments in his cave mansion. The old man in gray saw Han Yu's expression change, so he interjected.

"Is this true?" The words of refusal came to his lips and were swallowed again, and Han Yuhu asked suspiciously.

"Naturally, Brother Han, please take a look!" Shi Zhen and Han Yu had also been together for a while, and they also knew Han Yu's character, so they immediately handed a jade album to Han Yu.

Han Yu unceremoniously swept the Divine Thoughts in, and after a while, he put the Divine Thoughts away, looked at Shi Zhen and said, "It turns out that Ling Zu is Shi Zhenren's apprentice?"

"Well, my master also went to the Sea of Heavenly Fog to get some things from the cave, and I also relied on the things in it to get a pill. Shi Zhen did not hesitate and truthfully revealed the situation.
