Time simply doesn't allow it.

Qin Yi glanced to both sides.

The three-foot-high stone door on the right was also closed. Qin Yi only took a glance and knew that it had the same design as the one in front of him. As long as he entered or exited, an early warning would be issued.

"The Treasure Hall is also not feasible."

Qin Yi looked at the large hall at the end on the left, which had an unclosed but open huge stone door.

"The Heritage Hall is not closed."

Qin Yi thought for a while, then turned and walked towards the inheritance hall.

In front of the three walls of the inheritance hall, there are stone shelves with bone or jade slips placed on them.

At this time, four or five people in the inheritance hall took the bone slips and sat at the stone table in the middle to read.

Qin Yi maintained the unity of heaven and man and the state of invisibility, strolling through these bookshelves in a clockwise direction.

Miscellaneous books, history, exercises, secret techniques, secret medicines, utensils, etc. are classified like a high school library.

"The inheritance hall is open, and there are no restrictions on these bookshelves. It seems that Pluto is quite proud."

If you are willing to make the inheritance completely open, anyone in the underground palace can accept it.

However, they were much harsher on him, an outsider, and would not let him see any inheritance.

"No, not all are open. The inheritance related to the Qilin Formation is not stored here."

Qin Yi looked around and was disappointed when he couldn't find the books related to the Qilin Formation that he wanted most.

Qin Yi could only retreat and settle for the next best thing.

Miscellaneous books are books such as travel notes, diaries, and essays.

Qin Yi is not interested.

Qin Yi was somewhat interested in history, but the place was full of bone slips and there were no jade slips. Looking at the bone slips would alarm others.

give up.

Qin Yi mainly looked at the secret techniques and secret medicines.

Most of them use jade slips as carriers.

It's just that there are a lot of them, hundreds or even thousands. I want to see them all, but time and energy don't allow it.

I can only pick out a few important ones to read.

"The Qilin Book? This is a must-read."

Qin Yi read the jade slip and found that it was very similar to the seven-sided stone tablet erected in front of the Black Dragon Pond. In addition to the formulas of the Qilin Secret Technique, it also recorded the secret techniques based on it.

Putting down the jade slip, Qin Yi nodded with satisfaction.

"As long as you get the Qilin visualization diagram, you'll be all set."

Qin Yi randomly selected a few secret skills, took off the jade slips, and took a look. After visiting the secret skills area, Qin Yi shook his head and said: "The most core inheritance, the art of earth control, is not available here either.

"

It seems that the art of earth control, like the Qilin Formation, is the core inheritance of the Lord of the Underground Palace, Pluto, and will not be stored in this inheritance hall.

Qin Yi walked towards the secret medicine area.

"More than five hundred secret medicine recipes and more than thirty secret techniques."

Seeing this, Qin Yi couldn't help but be shocked by the details of the underground palace.

You know, this secret medicine can completely match the standard elixir.

Five hundred kinds of elixirs, which has reached the level of aristocratic families.

Qin Yi picked out a few secret medicines that were more important to him and read them over.

As for the more than thirty secret techniques, there weren't many anyway, so Qin Yi simply read them all.

After reading it, Qin Yi felt very tired.

After finding a corner, Qin Yi sat cross-legged and closed his eyes for half an hour before recovering.

"After my mind has reached the state of emptiness, I rarely feel mentally exhausted from reading jade slips. The last time was when I read the Jin Dan Essay at Changping Villa."

However, this time it is much stronger than last time.

Last time he rested for three or four hours before recovering, but this time he only recovered after resting for half an hour.

Qin Yi stood up, took a final turn around the inheritance hall, and casually looked at the jade slips in other areas.

"Tool making, it talks about how to make stone tools and bone tools. It really has the characteristics of the underground palace and the Guixu land."

After walking around for the last time and finding no other jade slips he wanted to see, Qin Yi left the inheritance hall.

Standing again in front of the three-foot-high stone door in the middle, Qin Yi felt helpless.

It would be great if this stone gate was open like the inheritance hall.

He can come quietly and leave quietly just like he did at the Heritage Hall.

It won't alarm anyone.

How good it is to be at peace with each other.

Suddenly, Qin Yi thought of something, snapped his fingers and said with a smile.

"It seems that this is the only way to use it!"
