The stone pier, which weighed hundreds of kilograms, was removed, revealing a pitch-black hole underneath.

The shadow of a staircase can be faintly seen in the black hole, Yu Haoran took a closer look, and sure enough, this hole can go down through the stairs, it seems that there should be a hole inside.

"Vivi, go get a lamp. Yu Haoran said to Wei Wei, who was standing aside.

Vivi was also surprised, and the child was more or less curious, and turned to run into the house to get the lamp.

Carrying the lamp in their hands, Yu Haoran and Wei Wei carefully walked down the somewhat steep stairs.

Originally, Yu Haoran didn't agree with Weiwei coming down, but Weiwei insisted and took two lamps.

Yu Haoran thought that the following was also a place in his home, and there should be no danger, so he agreed.

The stairs are not very long, only about three or four meters to the bottom, raising the lamp in his hand to shine around, Yu Haoran and Wei Wei were stunned.

In this underground secret room, there are dense books stored inside, and the tall bookshelves of ancient sandalwood exude a faint fragrance, and they are filled with dark yellow books.

Although the inside looks very old, the inside is very clean, and it seems that someone often cleans this place, needless to say, that person must be Yu Qiangsheng before his death.

Yu Haoran carefully took out a book on the shelf, opened it gently, and a line of words and pictures appeared in front of him.

After a brief flip through it, this is a medicine book, which records the medicinal properties and use methods of various herbs, and also depicts the shape of the herbs.

I put the book back, went to another bookshelf and took down a book, and simply flipped through it to see that it was a book on etiquette and morality.

In this way, I looked at several books on the shelves in a row, and I took out one or two books and flipped through them, and found that there were all kinds of books, with a wide range and clear distinctions, and the books on each shelf were of the same kind.

Wei Wei didn't have much interest in other books, only those medicinal herb books, so she picked up a large one and sat aside to read it.

Yu Haoran walked to the last bookshelf, on this shelf, there was only one book, very thick and large, and it was made of the finest thick parchment.

Taking down this book, Yu Haoran's eyes rose

I was immediately attracted by the big words on the cover.

The history of the Yu family!

Yu Haoran put the lamp on the bookshelf, turned the first page, and carefully looked at every word on it.

In the 449th year of the Demon Alchemy Continent, Yu Shen, the master of medicine in the mainland, established the Yu family, erected plaques, and built forces, Yu Shen saved countless people in his life, including many strong demon refiners, and the family power rose rapidly.

In the 594th year of the Demon Refining Continent, the Yu family was shocked by the aftershocks of geniuses, and at the age of forty, he became a nine-star demon refiner, the peak powerhouse of the continent, and once fought with two nine-star demon refiners and won a draw, which shocked the world!

The family's power expanded again, and it was called the four major families in the mainland together with the Jin family, the Wen family, and the Qiu family.

In the 668th year of the Demon Refining Continent, the Zhao family, the Ye family, the Lin family, the Wan family, the Long family, and the Mu family rose, and the Yu family's power reached the top, becoming the head of the top ten families in the mainland.

In the 868th year of the Demon Refining Continent, the Shangguan family and the Murong family rose, and the twelve families of the mainland took the rest of the family as the head to manage the entire Demon Refining Continent.

In the ninety-one year of the Demon Refining Continent, the Ouyang family rose, and the Jin family, the Wen family, the Qiu family, and the Mu family declined, and they withdrew from the ranks of the top families in the mainland.

The Yu family, the Ouyang family, the Murong family, the Shangguan family, the Long family, the Wanjia family, the Lin family, the Ye family, and the Zhao family became the nine major families in the mainland.

In the ninety-sixth year of the Demon Refining Continent, the power of the Yu family was gradually decreasing, and the power of the Ouyang family was faintly leading, and the nine major families divided the Demon Refining Continent, which was divided into one to ten rings.

Except for the first ring, the second to tenth rings are managed by one of the nine major families, and the rest of the families manage the land of the ten rings.

Seeing this, Yu Haoran's heart turned up a monstrous wave, he didn't expect that his family ancestor turned out to be a small doctor, and the Yu family has become the strongest family in the mainland from generation to generation, but after the establishment of the nine families, the Yu family began to gradually decline.

But now that there is no Yu family's status on the mainland, what happened next? Let his family fall, Yu Haoran hurriedly turned the next page.

As soon as he opened it, he was fixed there as if he had been immobilized, his mouth slightly open, and he looked at the words on it without moving.

The Demon Refining Continent lasted for a thousand years, and the Yu family was wiped out overnight!

The handwriting was much newer than the previous one, but it hit Yu Haoran's heart like five thunderbolts.

What the hell happened? Let the Yu family, one of the nine major families in the mainland, be wiped out overnight!

Yu Haoran was shocked in his heart at this time, but also shocked!

The Demon Refining Continent has lasted for a thousand years, isn't it the year I was born? It's a pity that I was still young at that time, and I don't remember anything or know anything.

Now this garbage-like Ten Rings, which used to be the jurisdiction of the Yu family, has now become like this.

Sixteen years, just sixteen years, the reputation of the Yu family with a history of more than 500 years has disappeared in the eyes of people, what a sad thing!

What happened sixteen years ago? Who did it? These are not mentioned in this book, and they are all created by some people in the Yu family.

If you hadn't looked at the history of the Yu family before, Yu Haoran might have been ecstatic after discovering these magic techniques.

But knowing that his family had a glorious history of more than 500 years, but it was destroyed and disintegrated overnight, he had no other thoughts.

put the Yu family's history record into the compressed bag, and Yu Haoran took Weiwei out of the underground secret room. Weiwei also brought out a book, which was a book of medicinal herbs.

The Yu family established the family as a doctor, and the ancestor Yu Shen was a medical master at that time, and it has a history of more than 500 years.

After coming out, Yu Haoran used a stone pier to re-block the exit of the secret room, and the things in it were all treasures of the Yu family, and there could be no mistakes.

Back in his room, Yu Haoran opened the history of the Yu family again, and asked the black impermanence in his body while looking at it: "Boss, do you know anything about our Yu family." ”

Hei Wuchang shook his head and said, "I don't know, when Lord Yan took me out of the continent, this continent was not called the Demon Refining Continent, but the Demon Duo Continent. ”

"At that time, the number of demons was more than the number of humans, and their strength was generally stronger, but now it has changed, and humans have dominated almost the entire continent. ”

Yu Haoran sighed regretfully, he really wanted to know what happened to his family, it seemed that he only needed to find clues when he went outside to experience by himself.

Looking at his left arm again, it was time to leave.
