There is a book in my Dantian

Evil Wolf Gang, in the rockery in the back garden!

The deeper you go into the passage, the more humid the air in the passage becomes, which indicates that the end of the passage may be underground.

Chen Hao, who followed closely behind Yu Lang, held the long knife tightly in his left hand, and carefully observed the situation in the passage while being alert to the surroundings.

Unfortunately, the light in the passage was very dim, and even with the illumination of torches, it was impossible to see the surroundings clearly.

Fortunately, the distance of the entire passage was not long. The two walked for less than three minutes and came to a stone chamber built entirely of bluestone.

"Chen Hao, this is the secret library of my Evil Wolf Gang!" Yu Lang said, pointing to the stone chamber built entirely of bluestone in front of him.

At this time, a trace of shock flashed across Chen Hao's face.

Being able to build such a stone chamber underground requires not only a huge figure, but also strong professional skills.

More importantly, bluestone is a special refining material. It can not only be used to forge weapons, but also has a very strong hardness. It is difficult for masters at the peak of the seventh level of Qi Refining to leave a trace on the bluestone.

The Evil Wolf Gang, which has no body-refining stage, was able to build such a stone storehouse. Chen Hao had to suspect that the backers behind the Evil Wolf Gang, in addition to wanting to share the benefits of Chaos City, might have other purposes.

"Chen Hao, please take out the key that Feng Lang gave you!" Yu Lang reminded him as he walked straight to the stone chamber and pointed to the two entrance marks on the stone door of the stone chamber.

"Here you go!" Chen Hao shook his head, temporarily putting aside his previous guess, and then took out the key that Feng Lang gave him from the storage bag, and gestured.

While taking the key, Yu Lang also took out an identical key from his arms, and then inserted the two keys into the marks at the same time.

With the creaking sound of the door opening, the tightly closed stone door slowly opened, and then a strong aura that he could not describe came to his face. The concentration of this spiritual stone was far greater than the concentration of spiritual energy formed instantly when the box containing all the lower-level ninth-grade spiritual stones was opened on the first floor of the Tiger Gang's treasure house.

"Chen Hao, please!" Yu Lang was both relieved and saddened by the shock on Chen Hao's face.

He was relieved because even a rare genius like Chen Hao was shocked, which was enough to prove that the treasures in the treasury were extraordinary and enough to show the strength of their Evil Wolf Gang.

He was sad because these treasures would not belong to the Evil Wolf Gang or the backers behind him.

After the rich spiritual energy dissipated, Chen Hao hurriedly stepped into the stone chamber and found that the stone chamber was divided into two areas, east and west, by shelves made of paulownia wood.

On the shelves in the westernmost area, there were six opened large boxes and a small box, each of which contained a pile of spiritual stones.

He walked straight to the shelf on the west side and took a closer look. Chen Hao found that the lowest-grade spiritual stone in the six large boxes was also a ninth-grade middle-grade spiritual stone, and most of them were ninth-grade high-grade spiritual stones.

The spiritual stones in the smallest box are not only bigger in size and more translucent in color, but also emit more than ten times the spiritual energy fluctuations of the ninth-grade middle-level spiritual stones.

"This, this is an eighth-grade spiritual stone!" Chen Hao took out a spiritual stone from it, held it in his hand and carefully felt the spiritual energy contained in the spiritual stone, and couldn't help but gasp and said.

"Yes, this is the eighth-grade lower-level spiritual stone!" Yu Lang, who followed into the stone chamber, confirmed from the side.

"Chen Hao, these eighth-grade lower-level spiritual stones are the spoils that my evil wolf gang finally seized after looting at least ten powerful caravans in a year." Looking at the eighth-grade lower-level spiritual stones emitting rich spiritual energy in Chen Hao's hand, Yu Lang said with a sigh.

As a master in the middle stage of the tenth major perfection of the Qi Refining Period, Yu Lang also has a very strong desire to improve his own strength.

If he could cultivate with the help of the lower-level eighth-grade spirit stones, it would take at most one month for his cultivation to reach the peak of the tenth level of Qi Refining Stage, and he would be able to break through the Body Refining Stage by five levels within half a year.

Unfortunately, he was not qualified to use even the middle-level ninth-grade spirit stones, let alone the lower-level eighth-grade spirit stones.

Because the spirit stones in front of him needed to be contributed to his backers.

The reason why they were able to successfully rob these caravans was not only because of the accurate information provided by the backers behind them, but also because of the help of the masters secretly sent by the backers behind them.

Otherwise, how could they know which caravans had the eighth-grade spirit stones, and how could they deal with the strong men in the Body Refining Stage in the caravans.

Chen Hao ignored the sigh in Yu Lang's tone, and used the strong wind to cover all seven boxes, and then put them all into the storage bag.

At this moment, the spirit stones stored in the storage bag could not only support him to break through the Body Refining Stage, but also within the tenth level of the Body Refining Stage, and he probably didn't need to worry about the shortage of spirit stones before advancing to the seventh level.

Then, he looked at the two shelves on the east side.

On one of the shelves were seven slightly dark books.

Taking a secret book from the shelf, Chen Hao found that it was actually a top-notch yellow-grade intermediate palm technique. After carefully reading the contents of the secret book, Chen Hao found that it was very suitable for his own practice, so he put it directly into the storage bag.

Then, he flipped through the other six secret books and found that among these six secret books, five of them were the top-notch yellow-grade intermediate skills, and the other one was a yellow-grade high-level sword technique.

Although he was not good at using swordsmanship, martial arts that reached the high level of yellow grade were very precious treasures that could be used to exchange for many treasures suitable for him, so Chen Hao put all of them into his storage bag without leaving any.

Then, his eyes turned to another shelf.

On another shelf were ten small boxes, three slightly grayish ores that looked like stones, and three spiritual weapons that exuded a hint of majesty.

Walking straight to the front of the three spiritual weapons, Chen Hao was surprised to find that there was a knife-shaped spiritual weapon among the three spiritual weapons.

Reaching out to hold the spiritual knife, Chen Hao immediately felt a strong repulsive force coming from the spiritual knife. This force seemed to resist his approach, which shocked him and immediately gave him a sense of dissatisfaction.

He mobilized the spiritual power in his dantian and began to fight against the repulsive force coming from the spiritual knife with all his strength.

The spiritual power at the peak of the seventh level of the Qi Refining Period was dispersed at the slightest contact.

The spiritual power of the eighth level of Qi Refining Stage was also dispersed as soon as it came into contact.

The spiritual power of the ninth level of Qi Refining Stage was also dispersed as soon as it came into contact.

The strength of the tenth level of Qi Refining Stage, which was at its peak, only lasted for less than half a second and was also dispersed by the repulsive force.

Gritting his teeth and stamping his feet, Chen Hao directly used all his strength. This time, he lasted for three seconds, but the final result was still being dispersed by the repulsive force.
