Cheng Yaojin went to find what Zhang Nan wanted, and Zhang Nan searched the formula and proportion of the black gunpowder in the system. After searching, the proportion of the black gunpowder was only a simple sentence: "1s:2kno3:3c, referred to as one sulfur, dinitrogen, and three charcoal."

As a result, Zhang Nan had to wait obediently for Cheng Yaojin to take back what he wanted. It was not until the sun was shining brightly at noon that Cheng Yaojin came back with two sacks. Zhang Nan looked at Cheng Yaojin holding one in one hand, and Zhang Nan thought in his heart that even if Cheng Yaojin was not a general, even if he went to carry a big bag for others, he would earn more than others in his body.

However, after a closer look, there was a man following Cheng Yaojin, who was walking here with a sack in his arms. Wasn't this an official who used the fireworks he set out as auspicious official from the sky? What did he come here for? Zhang Nan thought strangely.

Cheng Yaojin walked to Zhang Nan, threw two sacks on the ground and said in a search for credit: "Qingquan, you have found what you want."

Without waiting for Zhang Nan to speak, Yuan Tiangang took two steps to come to Cheng Yaojin's side, put the sack aside, and said breathlessly: "General Cheng, you are leaving too fast. Old Taoist, Old Taoist can't keep up."

"Hey, I said, Old Dao Yuan, you are so tired after only a few steps." Cheng Yaojin said with contempt.

"Hu, Huhu, General Cheng, let me give me a glass of water first." Yuan Tiangang ignored Cheng Yaojin's contempt and asked for a glass of water.

Cheng Yaojin sent someone to pour a cup of tea for Yuan Tiangang and said to Zhang Nan: "Qingquan, come on, let me introduce it. This is the head of the Taishi Bureau, Yuan Tiangang, Yuan Laodao." After Cheng Yaojin finished speaking, he turned to Yuan Tiangang and said, "This..."

Before Cheng Yaojin could finish his words, Yuan Tiangang said first: "This old Taoist knows you. Isn't this Lord Zhang who was just named Director of the Labor Reform Bureau by the Emperor?" Yuan Tiangang said with a smile.

"Good luck to meet." Zhang Nan quickly bowed his hand when he heard the old Taoist in front of him.

Yuan Tiangang is also a strange person in history. This is an ancient Chinese astrologist, a scholar, a Taoist priest, a Feng Shui master, and a prophet. Zhang Nan knew two things about Yuan Tiangang's deeds.

One thing is to look at the queen Wu Zetian. When Wu Zetian was still in her childhood, Yuan Tiangang was surprised to see Wu Zetian's mother, Yang, and said in surprise: "Madam, give birth to a noble son!" Wu Zetian's mother took two sons Wu Yuanqing and Wu Yuanshuang to send Yuan Tiangang to meet him, but Yuan Tiangang saw that he could reach the third rank, but he was the head of the family, and was not very noble. Yang also called Wu Zetian's sister to let Yuan Tiangang look at him, and Yuan Tiangang said, "This woman is noble but not good for her husband!"

Finally, the servants carried out Wu Zetian dressed in boy's clothes. Yuan Tiangang was shocked when he saw Wu Zetian in the cradle and said that she "dragon eyes and phoenix neck are extremely valuable!" But he said regretfully: "If it is a woman, it is really impossible to see, and he will be the lord of the world in the future!"

The second thing was that Li Er asked Yuan Tiangang and Li Chunfeng to calculate the national fortune of the Tang Dynasty. Li Chunfeng used the Zhouyi Bagua to calculate it. Unexpectedly, he became addicted as soon as he calculated it. He was out of control. He actually calculated the fate of China for more than 2,000 years after the Tang Dynasty. Until Yuan Tiangang pushed his back and said, "You can't let go back and rest."

So we came up with this wonderful book of prophecy, "Tuibei Tu". "Tuibei Tu" has a total of 60 images, each image is accompanied by a prophecy and a regular verse of "Songyue", which predicts the main events that took place in Chinese history from the Tang Dynasty to the future.

These are things that Zhang Nan knew about, and Zhang Nan didn't know about other things, but Zhang Nan still admired Yuan Tiangang's ability. As for whether Zhang Nan believed in the face of the face or not, it can only be said that Zhang Nan did not believe in the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face of the face, Zhang Nan would still believe it. After all, the explanation of this thing is not clear, but it can be passed down for thousands of years, and there must be a reason for its existence.

Yuan Tiangang also quickly bowed and said, "Good luck to meet." After Yuan Tiangang said that, he couldn't help but look at Zhang Nan's face. When Yuan Tiangang stared at him, Zhang Nan felt very strange.

"What's wrong? Is there any flowers on my face?" Zhang Nan couldn't help but touch his face and said.

Yuan Tiangang ignored Zhang Nan and looked for a while before saying, "Strange, it's really strange."

When Cheng Yaojin heard that Yuan Tiangang was fighting the puzzle, he was immediately dissatisfied: "I said, "I said, "What's the strange thing about me?"

"No, no, no, the old Taoist just thought Lord Zhang's face was very strange, and the old Taoist also understood a little bit of the face." Yuan Tiangang stroked his beard and said.

"If the Taoist priest doesn't dislike me, just call me Qingquan. Why do you have to be so disgusted?" Zhang Nan said with a smile.

"Then it's better to obey your orders than respect. Old Taoist Guan Qingquan's face is a sign of death early. But when you look closely, this evil appearance seems to be a good appearance, and it's a bit like a rising star. It's really strange." Yuan Tiangang said to Zhang Nan's face.

When Cheng Yaojin heard Yuan Tiangang say that Zhang Nan died early, he was immediately dissatisfied. "I said to you, what are you talking about? Look at Qingquan, where is the appearance of death early? Don't talk nonsense." Cheng Yaojin said.

Although Yuan Tiangang said that he died early, Zhang Nan didn't care at all, but was shocked. For himself who had not traveled through time, he was indeed dead. He was shocked. He was shocked by electricity, was still unconscious, and even traveled to the Tang Dynasty. For himself in later generations, he was indeed dead. But for himself now, he was still rising to the top, and Yuan Tiangang saw it well at all.

"Ah, the old Taoist said something wrong for a moment. Don't blame Qingquan. The old Taoist has such a hobby and likes to show others his appearance." After Yuan Tiangang said this during the Sutra, he realized that what he had just said subconsciously was not appropriate, so he quickly said it.

"It's okay." Zhang Nan waved his hand with a smile, but thought to himself: "How could you blame you? When I'm about to burp in the future, I'll ask you to help me see a Feng Shui treasure land."

Anyway, Zhang Nan didn't think that he would die in the Tang Dynasty one day, so he had to let Yuan Tiangang take a look at a place that would benefit future generations.

"Okay, don't be polite to you two. Old Dao Yuan came here today to ask you something." Cheng Yaojin said to Zhang Nan.

"Is there something to ask me? What's the matter with Taoist Master Yuan?" Zhang Nan asked strangely. He had just met Yuan Tiangang twice. What could Yuan Tiangang have to ask himself?
