Chen Yang and Han Li winked, then turned around and walked into the door.

Han Li and Gu Qianxun looked at each other and followed.

The space in the secret warehouse is quite small, comparable to a palace. There are seven or eight tall counters in the secret warehouse, made of a kind of black wood.

This wood looks like an unusual thing, exuding a quiet fragrance, filling the entire secret library space.

Each counter is divided into three layers, and there are many boxes, wooden boxes and other objects placed on each layer, which contain various precious materials, martial arts and scriptures, animal cores, etc.

Han Li ignored the counters and looked straight at the center of the secret library.

There was an open space there, with a black stone pillar more than one person tall, with earthworm-like patterns engraved on the stone pillars.

At the top of the stone pillar, a black crystal was placed the size of a human head.

This crystal is as smooth as a mirror, emitting bright black light, rippling towards the surroundings like black water waves. A strange energy fluctuation can be vaguely sensed in the black light.

Han Li only felt that as soon as he stepped into the secret library space, the black robber insect in his body touched this strange energy, and immediately stopped moving and fell into a deeper sleep.

"Black Stone!"

Han Li's heart moved, but glanced at Chen Yang next to him and did not immediately take action to get it.

Gu Qianxun also looked at the black crystal, and a trace of surprise flashed in his originally cold eyes.

"Fellow Daoist Li also knows the Black Tribulation Stone? However, this object can only suppress the Black Tribulation Stone and cannot drive it away. Just look around to see if you can find a way to remove the Black Tribulation Stone. In addition, please forgive me, the situation outside is changing rapidly now, and we cannot delay here for too long, at most half an hour." Chen Yang seemed to see what Han Li and the others were thinking, and said so.

Gu Qianxun nodded indecisively, walked to a counter, and began to search.

When Han Li heard this, he also withdrew his gaze and began to search around.

The demonic energy and fairy power cannot be used in the Jilinkong realm. Although this is a secret library, there are basically no prohibitions or other things.

The search of the three people progressed rapidly, and soon the entire secret library was searched.

After a stick of incense, Han Li put down a book with a look of ugly expression and looked at Gu Qianxun next to him.

Gu Qianxun also looked over at this time, his face a little solemn.

The two of them were not at ease with Chen Yang, so they tacitly took over the search for all the classics and asked Chen Yang to search for other items.

However, the two of them looked up all the classics, but they didn't even see the word "Black Tribulation" in the word "Black Tribulation".

"I have found some useful information here, two fellow Taoists can come and take a look." At this moment, Chen Yang's voice came.

Han Li and Gu Qianxun walked over quickly when they heard this.

Chen Yang was standing in front of a counter at a corner. A black crystal box about the size of a foot was placed on the counter. Through the translucent box wall, you could clearly see black centipede monsters lying inside, which were the black catastrophe insects.

He held a black jade board in his hand, looking at the texture of the crystal box, as if it were part of the crystal box, with lines of dense small characters written on it.

Chen Yang handed the black jade board to the two of them, and Han Li and Gu Qianxun read it in one glance.

Soon, both of them looked gloomy.

The jade board describes the method of cultivating black robbery insects. From birth to what to feed and grow up, and how to plant them into the human body, the records are very detailed, but there is no way to take them out.

However, the jade board mentioned the black catastrophe stone. The black catastrophe is a group species. Each black catastrophe group has an insect king, commanding the other black catastrophe insects.

The black robbery stone is a special crystal substance condensed by the corpse of the Black robbery insect king and using secret techniques, so it has the effect of suppressing the black robbery insect.

To suppress a black catastrophe, it is enough to just carry a black catastrophe stone the size of a fingernail on it.

"These two black catastrophe stones, two fellow Taoists, put them on their bodies first to suppress the black catastrophe insects." Chen Yang walked to the black catastrophe stone while the two of them were reading the contents of the jade board, split two black crystals the size of an egg, and handed them to Han Li and the others.

"According to what is said above, it seems that such a big piece is not used." Han Li said.

"Although I said so above, it's always safer to have more." Chen Yang said with a laugh.

"In this case, I would like to thank fellow Taoist Chenyang." Han Li did not hesitate, thanked him and put the black robbery stone in close proximity.

Gu Qianxun also put away the black robbery stone, but his eyes were still looking at the black jade box.

"Does fellow Taoist Bone want to get some black robbery insects? Please use them as you like, but you have to use a special utensil to hold this worm." Chen Yang said when he saw Gu Qianxun's gaze.

"There are no large black catastrophe stones, it is useless to make these black catastrophe insects. Look here." Gu Qianxun shook his head and pointed to the side of the black crystal box.

It happened to be the blind spot of Han Li's sight. Han Li walked to Gu Qianxun and saw what the woman was referring to.

I saw a six-petal flower pattern engraved in the crystal box, which was quite exquisite and seemed to be some kind of mark.

This pattern is very shallow, and it is very ugly if you don't look carefully.

"Daoist Doctor recognizes this pattern?" Han Li asked with his eyes fixed.

This pattern is engraved on this black crystal box, and it should not be aimless.

"I haven't come to Qingyang City before, and I have seen this pattern in Xuancheng. It is a unique mark of a sword-casting master, Mrs. Liuhua." Gu Qianxun said slowly.

"Madam Liuhua? It sounds like she is a woman, but it is rare for female sword-making masters to be a master." Han Li touched his chin and said.

"I have also heard of Mrs. Liuhua's name. He is not a woman. There is a tribe named Baiyi in the holy realm. He is proficient in sword-making and refining weapons. Only those with the highest skills in refining weapons can get the title of "Madam". Senior Liuhua is the wife of this generation of Baiyi tribe. Somehow, he was thrown into the Jilin Kong Realm by the Yeyang Dynasty a million years ago. He has lived in the main city of Xuancheng for many years. All the weapons he refines are fine and it is hard to find. Du Qingyang wanted to get a handy weapon, but he failed to succeed." Chen Yang shook his head and said.

"So that's it, just Mrs. Liuhua's mark, how could it appear on this box?" Han Li said with some confusion when he heard this.

"It seems that this box was written by Mrs. Liuhua, or what does it have to do with these black robbery insects?" Gu Qianxun frowned and murmured.

"There is still a little bit of searching the secret library. Let's finish searching first." Chen Yang suddenly interrupted.

Han Li looked up at the front and saw that there was still the last cabinet left without exploring it, but the cabinet was placed with various materials and some various debris.

Although the hope was slim, the three of them still took action together and carefully searched for the last cabinet.

Han Li picked up a fluorescent purple-black crystal stone, and carefully investigated it. He did not find anything hidden inside, so he put it down and picked up another item next to him.

"Huh!" Han Li's expression changed slightly.

This object is a black relief the size of a palm, carved by a demon with three heads and six arms, sitting there in a weird posture.

He had seen this thing before, and there was such a black relief in the storage magic weapon of Zhaogu Zhenren.

Both the reliefs are exactly the same in size and materials. The only difference is the postures of the two statues of the demon gods.

"Could it be that these two statues have any connection?" Han Li secretly guessed in his heart. Chao Chenyang and Gu Qianxun looked at him. Both were investigating other things and did not pay attention to the situation on his side.

A flash of his eyebrows, and a crystal light shot out from it and penetrated into the relief.

The black relief shook slightly, and then came alive and danced his hands and feet, posing in various positions, with a total of twelve types in front and back. Each time one posture was made, many strange and unimaginable words appeared behind the relief.

However, the twelve postures of this relief are completely different from the reliefs of Zhaogu Zhenren. Although Han Li does not recognize these strange words, he can also see that they are different from those before.

A hint of joy flashed in Han Li's eyes. This relief was indeed closely related to the relief of Zhaogu Zhenren, and it seemed to be a set of things.

He casually looked through the black relief twice, and soon put it back in the distance as if nothing had happened.

The three of them quickly searched all the items on the counter, and as expected, there was nothing that seemed valuable to gain.

The only valuable information found in this secret library was the black jade board, so the three of them gathered next to the black jade box.

"No matter what, this is a clue." Han Li looked at the six-flower mark on the jade box and said thoughtfully.

Gu Qianxun didn't say anything, but just looked at Chen Yang.

"I'm so sorry, I couldn't find the way to relieve the Black Tribulation Worm for you. But when I clean up Du Qingyang's remnants, I will send additional staff to continue investigating and give you two a satisfactory answer." Chen Yang showed a look of shame.

"Satisfied reply? Does fellow Taoist Chenyang mean to ensure that he can find the solution to the Black Tribulation Worm? But I don't know when?" Han Li frowned slightly at this time, and then asked indifferently.

"Only Du Qingyang knows the way to relieve the Black Tribulation Worm. Now that he is dead, Chen will try his best to continue searching in the city lord's mansion and other places, and at the same time, he will try to find out the news from Xuancheng, which should be found." Chen Yang said hurriedly.

"It should be found? Fellow Daoist Chen, you can avoid such perfunctory words. Please give us a definite explanation about the issue of the Black Tribulation Worm." Gu Qianxun said in a cold tone.

"It seems that the two have joined forces long ago and don't seem to plan to continue working with Chen?" Chen Yang looked at Han Li and the other two, his eyes flashed coldly, and his tone became colder.

A white light flashed on his left arm, and a layer of crystal white faintly appeared on his skin. A huge and fierce aura suddenly burst out and suddenly came towards the two of them.

This aura is extremely huge, no less than Du Qingyang before, and it is extremely sharp. The nearby void seems to be cut by countless extremely sharp forces, buzzing and trembling.

Han Li and his two bodies seemed to be suppressed by the huge peaks, and they were sank, but their expressions changed slightly, and they immediately released their breaths, united with each other, and actually resisted Chen Yang's pressure.
