Chapter 508: Surprise! The old poisoner got the poison recipe!

The guards looked at each other, with a trace of panic and helplessness in their eyes.

One of the guards said cautiously:

"Sir, this poisonous fog is too strong, we really dare not approach rashly."

The middle-aged man glared at him fiercely:

"A bunch of trash! Can't even keep two people under control!"

Another guard hurriedly said:

"Sir, calm down, those two people are cunning, especially the one who can poison, whose strength should not be underestimated. What should we do now?"

The middle-aged man roared:

"Search immediately! Even if you turn the Spirit Hall upside down, you must find them!"

"Yes, sir!"

The guards responded in unison, and then scattered around to look for the two people's traces.

On the other side.

Zhuge Lan and Dugu Bo were teleported to another room in the Spirit Hall through the space-time gate.

This is a room that looks like the storage room of the Spirit Hall, surrounded by some tall and old bookshelves.

The bookshelf was filled with all kinds of books and files, which seemed to tell the unknown history of the Spirit Hall.

"Where is this?"

Zhuge Lan looked at the items in the room curiously.

Dugu Bo immediately looked around vigilantly, his soul power surging slightly, and he was always on guard.

Zhuge Lan said with a little surprise:

"This seems to be the library. Could it be that we will be directly teleported to the library of the Spirit Hall? Such a big Spirit Hall, there must be many treasures hidden in this library!"

Zhuge Lan's tone was full of expectation.

Dugu Bo ignored him.

He snorted coldly:

"Don't be careless, this is the Spirit Hall, and we don't know what dangers are waiting for us."

Zhuge Lan waved his hand nonchalantly and smiled:

"Old Poison, you are just too nervous. Look, we have successfully gotten rid of them."

As he said, he walked to a bookshelf, picked up a book and flipped through it.

Dugu Bo frowned, watching Zhuge Lan's casual behavior, and warned him vigilantly:

"Don't move, you'll be finished if you trigger some mechanism."

But Zhuge Lan didn't respond to his reminder.

He was about to say something, but was interrupted by Zhuge Lan's exclamation:

"Wow, old poison, come and see! What is this?"

Zhuge Lan waved the book in his hand excitedly, his face full of surprise.

"What is it?"

Dugu Bo asked in confusion, walked over quickly, and took the book from Zhuge Lan.

[Emotional Points +987654]

[Emotional Points +666666]

[Emotional Points +123456]

He took a closer look, and a trace of surprise flashed in his eyes:

"This... Oh my, this is actually a secret recipe for making poison?"

Dugu Bo muttered to himself.

Zhuge Lan nodded excitedly and said:

"Yes, yes, you see it is written here, the conditions for the success of this secret recipe are very harsh, it requires a poison soul master above the Soul Douluo level with a very strong poisonous spirit to succeed, isn't that you! Old Poison, you are really lucky!"

Dugu Bo was not as excited as Zhuge Lan. He looked at the secret recipe carefully and said puzzledly:

"This matter may not be as simple as imagined. How can there be such a thing in the library of the Spirit Hall?"

Zhuge Lan patted He patted Dugu Bo on the shoulder and said with a smile:

"Oh, you just think too much. Why are you always suspicious? Maybe it's God's blessing on us. Think about it, in the entire Douluo Continent, there are very few poison soul masters like you who use poison as their martial spirit. Moreover, his secret recipe still requires poison soul masters above Soul Douluo to make it, which is even rarer. So it's normal that he can't make it even if he gets the secret recipe and put it in the library."

Dugu Bo thought about it and felt that what Zhuge Lan said didn't seem to make sense.

He pretended to be embarrassed and said:

"Okay, in this case, then I will reluctantly accept this secret recipe, so that it can really play its role."

Dugu Bo touched the poison formula with satisfaction and put it in his pocket without hesitation.

Zhuge Lan also saw through his thoughts and said with a grin:

"You old poisoner, I don't understand you? You say no, but your hands are honest. However, if you can refine this kind of poison, your strength will be greatly improved."

Dugu Bo rolled his eyes at Zhuge Lan and said unhappily:

"You are so smart. But it must be difficult to refine this poison. I have to go back and study it carefully."

Zhuge Lan nodded, and his eyes scanned the bookshelf again, muttering:

"Maybe there are other good things, let's look for them again."

As he said, he began to shuttle between the bookshelves and search for treasures as if he had found a treasure house.

Dugu Bo shook his head helplessly and reminded him:

"Hey, don't forget why you are here, are you going to save the people?"

Zhuge Lan replied without turning his head:

"Oh, I know, I know, I will definitely save the people, but this ready-made treasure can't be missed. Maybe I can find some powerful things and save people more easily."

After all, it's rare to come to the library of the Spirit Hall. Logically speaking, the world's number one Spirit Hall must have a lot of treasures.

It's just right to see what is unlocked in the system atlas in Zhuge Lan's mind.

If you can unlock one or two illustrations, you can get some good rewards.

But Dugu Bo became anxious:

"Hurry up! I don't want to stay here for a moment anymore. The longer I stay, the more dangerous it will be. I'll be in trouble when those people from Wuhun Palace come to find me."

Zhuge Lan also saw Dugu Bo's thoughts. After all, this Wuhun Palace was the place where Dugu Bo's inner demons were.

I think back then he almost confessed here...

"Okay, okay, then let's go and save Su Biluo first, save people first and then talk about it."

Zhuge Lan reluctantly looked at the books and scrolls on the bookshelf, then turned and walked towards the door.

Zhuge Lan quickly walked to the door, raised his right hand and pushed hard.

However, the door remained as motionless as the mountain.

His expression suddenly changed slightly, his brows furrowed, he gritted his teeth and pushed again with greater strength.

But the door still showed no response, as if it was firmly imprisoned by a mysterious and powerful force.

"I'm so impressed. Why is this door locked?"

He cursed in a low voice, his tone full of helplessness.

Dugu Bo also walked over and saw him raising his left hand.

Then, he concentrated this soul power on his hands and gently applied it to the door.
