Tang Xiaobao was thinking about something and frowned from time to time.

Lan Nu occasionally opened her eyes and saw that Tang Xiaobao's expression was not right. She couldn't help but ask, "Master, is there something on your mind?"

"No." Tang Xiaobao said with a smile.

Lan Nu blinked: "But Lan Nu can feel it, the master must be worried. Can you tell Lan Nu, Lan Nu is now a spirit king and can help the master."

Tang Xiaobao's heart moved, and he asked, "Lan Nu, if you say so, I'm really a little worried. I want to develop a new drug, and I've found a pharmaceutical factory, but how can I prevent the formula from leaking out?"

Lan Nu blurted out: "Master, this question is too simple."

"Ah?" Tang Xiaobao was stunned: "Simple?"

"Yes, as long as there is enough jade, it will be fine."

"What do you mean?" Tang Xiaobao suddenly became interested.

Lan Nu continued, "The process of refining the medicine doesn't matter, but when synthesizing the various medicinal juices, they must be made in the right proportions. A slight difference can make a world of difference in the effect. So, for the final stage of synthesizing the medicine, we can install a small magic circle on the equipment. The medicinal juice will automatically be synthesized according to the formula's proportions, which solves this problem. Of course, jade is needed to set up the magic circle."

Tang Xiaobao swallowed his saliva. "Is it that simple? Jade can be used in this way?"

"Of course. Jade is specially used to set up magic arrays. It can not only be used in the pharmaceutical production process, but also can be used to set up magic arrays in medicine fields. This can ripen the medicines, and the efficacy will only be better." Lan Nu explained.

Tang Xiaobao's eyes lit up: "That's great, it seems you can set up a magic circle?"

"Well, Lan Nu, of course I can. I can set up any complex magic circle, but I need jade." Lan Nu said happily, "As long as I have jade, I can help my master set up the magic circle."

Tang Xiaobao was full of confidence: "Isn't it just jade? Let's go find it wherever we can find it."

"I don't know much about this, but I heard recently that there are people gambling on jade in Yunnan. Jade is very expensive. The owner can go there to find jade, which will save a lot of money." Lan Nu began to give advice.

Tang Xiaobao was stunned: "But I don't know how to gamble on stones, and I don't have X-ray vision, so how can I know if there is jade in the ore?"

He was a little depressed now. He opened the system and took a look. His reputation value had reached level nine, but it was probably still far from level ten. Even if he reached level ten and obtained a new title, he might not be able to draw the perspective skill.

This skill of perspective is what Tang Xiaobao has always been obsessed with!

Lan Nu said, "Master, don't worry. We are here. We ghosts are particularly sensitive to jade, and jade is the nemesis of ghosts. Once we get close, there will be a reaction."

Tang Xiaobao frowned and said, "Isn't that dangerous? No, I can't let Lan Nu take risks."

Lan Nu was naturally very happy and touched when she heard this. She squeezed closer to Tang Xiaobao's arms and smiled sweetly, "Master, you don't have to worry. Lan Nu is not an ordinary ghost. I am a spirit king. Even a jade stone engraved with a magic circle can't necessarily hurt me. What's more, ordinary jade is not dangerous to me at all."

"Okay, that's great." Tang Xiaobao was overjoyed. He often read novels and saw plots about gambling on stones. He didn't expect that he would have the opportunity to gamble on stones, and he was guaranteed to make money. He liked Lan Nu more and more. This little girl knew a lot of things.

"Let's go to Yunnan tomorrow. There's no time to lose. I will have to report to university soon." Tang Xiaobao made a quick decision and decided to go to Yunnan to gamble on stones.

The two sat for a while and were about to get up and go home when Lan Nu suddenly trembled, sat up, and floated in the air. He said vigilantly: "Master, someone is coming, huh? This smell is very familiar, it's the killer from last time!"

"Wild wolf?" Tang Xiaobao was shocked.

Lan Nu nodded and said, "Master, this is a desolate mountainous area. Opportunities are rare. We must not let him escape again this time."

Tang Xiaobao rubbed his hands together and said, "Hey, in a place like this, even if he grows wings, I will make sure he can't fly away."

After saying that, Tang Xiaobao stood up.

He seemed to sense that danger was approaching, but he had no idea from which direction it was coming.

"Hahahaha, Tang Xiaobao, let's see where you can run this time."

The figure of Silver Wolf suddenly appeared from behind a rock in front, holding a pistol in his hand, pointing it at Tang Xiaobao's head.

The two men were only more than ten meters apart. At this distance, Silver Wolf was full of confidence in his marksmanship. He had been in the special forces and was a well-known sharpshooter in the army.

Tang Xiaobao swallowed and watched closely the hand holding the gun of Silver Wolf. As soon as Silver Wolf moved, he was ready to teleport.

He wasn't sure if he could move away at such a short distance, but he was still not particularly scared because he knew that Lan Nu was still in the dark.

What we need to do now is to stabilize Silver Wolf and create opportunities for Lan Nu.

But this time, Silver Wolf was obviously on guard. As soon as he finished speaking, he opened fire without any warning.

Tang Xiaobao had just blinked and had no time to dodge.

A white shadow suddenly appeared in front of Tang Xiaobao.

Bang!

Gunshots rang out.

Lan Nu did not fall down.

"Master, don't worry. The bullet can't hurt me."

The bullet entered Lan Nu's body, but it disappeared as if it had entered a quagmire.

Silver Wolf couldn't see Lan Nu, and when he saw Tang Xiaobao standing there just fine, he frowned. Without thinking too much, he fired N shots in a row.

The bullets are all used up.
