The sun is shining and the blue sky looks particularly high. Even when riding a horse, the oncoming wind brings a little chill, which makes Zhang Zong feel a bit cool in autumn. Although it is still at the turn of summer and autumn, there is still some time before the real autumn.

"Brother Shi, are you sure there is something you are looking for here?" Xue Shao, who was behind him, immediately stepped forward, followed by a team of guards, and many other guards were scattered out to inquire about the news.

"Don't worry, there must be here!" Zhang Zong said with great affirmation, while also looking at the surrounding mountains and rivers. Although more than a thousand years will cause huge changes in the land, such as the location of cities, villages and forests, and even rivers will be diverted, the location of mountains and rivers will generally remain unchanged, so he also used the surrounding mountains and rivers to confirm the memories of later generations.

"Okay, but Brother Shi, you finally rescued Shangguan Wan'er, but threw her into my house. You have been running to Xianyang for three days. Don't you want to go back and take a look?" Xue Shao asked again at this time. It has been three days since he was out, and there is nothing else. The key is that he spent most of his time eating dry food, which made him, who has always been picking on his mouth, feel a little unbearable.

"It is precisely because I want to save people to the end that I came out. I told you that I would come out for several days and asked you not to follow me, but you didn't listen. Now you are suffering, right?" Zhang Zong saw what Xue Shao was thinking at a glance, and immediately smiled.

"Who... who suffered? I'm very happy now. The mountains and rivers here are much better than the scenery in Chang'an!" Xue Shao still felt so strong that he refused to admit it, but in fact he had already complained.

After Xue Shao said that, he turned his face and refused to look at Zhang Zong again. He also remembered in his mind three days ago, the day after his mother rescued Shangguan Wan'er. Zhang Zong ran to mutter to his mother for a long time, and then his mother sent most of the guards in the mansion to Zhang Zong. At that time, he just thought it was fun, so he also clamored to come.

However, Xue Shao didn't expect that it would be so hard to go out. He thought he could follow Zhang Zong to Xianyang and taste the local delicacies, but he didn't expect that Zhang Zong did not enter Xianyang City at all, but took them to the northwest of Xianyang, wherever there was a mountain to go. It was rare to even meet a village in the village, but they couldn't see many wild animals. They even encountered a tiger in the forest yesterday. Fortunately, they brought their guards, which made the tiger frightened and ran away.

"Okay, when I find what I am looking for, I will make a big meal for you when I go back, and I will make sure you make up for the hard work you have done in the past few days!" Zhang Zong couldn't help but smile when he saw Xue Shao's appearance, and immediately rode over and patted his shoulder and said.

Hearing Zhang Zong say this, Xue Shao turned his face and smiled a little. At this moment, a knight suddenly rushed from a distance and reported loudly: "Report! There is a porcelain workshop in front of him. According to the craftsmen in the workshop, they may have seen what the young man said!"

"That's great!" Zhang Zong also shouted excitedly when he heard this, and then asked the knight to lead the way. After turning over a forest, there was a big road ahead. Not far along the road to the northwest, he soon saw a large village and town. At the entrance of the village and town, there was a sign with the three big words "Baiyao Town" written on it.

"So Baiyao Town is here? I thought it was on the edge of Chang'an!" Xue Shao also showed a surprised expression when he saw the three words Baiyao Town.

"Do you know here?" Zhang Zong also showed a surprised expression when he heard Xue Shao's words. To be honest, they spent most of the days in the wild. Now he only knows that he is in the northwest of Xianyang, but he doesn't know the specific location.

"I have heard that many of the porcelain used in Chang'an are from Bai Kiln. The white porcelain fired here is quite good. Although it is not as good as Xing Kiln in Hebei, it is one of the best in Chang'an area." Xue Shao introduced. Of course, he had only heard of the name of Bai Kiln, and did not know that Bai Kiln was actually in Xianyang.

The knight in front led the way, and Zhang Zong and his group soon came to a porcelain workshop outside Baiyao Town. In fact, the entire town mainly made a living by burning porcelain. There were porcelain workshops around the town, and most of the residents in the town were the families of craftsmen and some merchants coming and going.

Zhang Zong and the others waited at the entrance of the workshop for a while, and the knight quickly brought an old craftsman over. Seeing Zhang Zong and others with extraordinary temperament, he hurriedly bowed and said, "You guys are polite, are you looking for a black charcoal-like stone?"

"No, my father-in-law, have you ever seen such a stone?" Zhang Zong also stepped forward anxiously and asked.

The so-called black stone naturally refers to coal. After he came to Xianyang these days, he has been inquiring for a long time, and he has also come to search on the spot in person, but there is still no clue.

Princess Chengyang pulled her face down and forced Shangguan Wan'er out of the palace. Although Li Zhi would not do anything to Princess Chengyang because of such a "small matter", it is inevitable to scold her in the future. If Wu Meiniang was behind the scenes, it would make Princess Chengyang very passive.

Princess Chengyang did these things just to help him, so Zhang Zong would definitely not sit idly by. What he could do was to help Princess Chengyang make another great contribution. No matter how big the mistake was, Li Zhi would definitely not take it seriously. As long as Li Zhi's attitude towards Princess Chengyang remained unchanged, no matter how others made trouble, it would be useless. This is Zhang Zong's plan.

"It's not just that I've seen it. The old man almost died of such a stone before!" The old craftsman also smiled bitterly.

"How do you say this? Can this kind of stone still eat people?" Xue Shao next to him asked curiously when he heard this. He only knew that Zhang Zong was looking for a black stone called "coal", and Zhang Zong did not say anything else to him.

"Young man doesn't know that our Baiyao Town makes a living by firing porcelain. In addition to the craftsman's craftsmanship, the most important thing is the quality of porcelain clay. Even if a good or bad porcelain clay is the best, it can still burn good porcelain if a good porcelain clay is fired by an apprentice. But if it is a low-quality porcelain clay, even if a master is fired by a fire, he may only burn the low-quality porcelain..."

This father-in-law was old and spoke a little long-winded. When he even started to tell Zhang Zong and the others about the skills of burning porcelain, they were also a little anxious. Fortunately, the father-in-law quickly began the topic. It turned out that when he was young, he also had a porcelain firing workshop at home, occupying a good piece of porcelain clay mine. The porcelain fired was one of the best in Baiyao Town.

But as the saying goes, there are unexpected events. Just when my father-in-law's business was very prosperous, he didn't expect that the porcelain clay mine that originally produced good porcelain clay was suddenly dug, and only a kind of black stone was left below, and it was impossible to make porcelain at all.

Although the old craftsman later found another kind of porcelain clay ore at his home, the quality of the porcelain burned was significantly reduced due to the different quality of the porcelain clay. In addition, some changes occurred in his home, which caused the original business to collapse suddenly. He could only burn porcelain for others in this workshop now.

"That's great!" Zhang Zongwan shouted excitedly, but then he felt something was wrong, so he explained to his father-in-law awkwardly, "Don't get me wrong, the black stones under your mine are probably what we are looking for. Can you take me to see? No matter what the situation is, we will thank you very much!"

"Okay, the land deed of that mine is still in my hands. If you want that kind of black stone, you might have to buy land from me." The father-in-law was very open-minded and did not blame Zhang Zong. He nodded immediately and agreed.

At the moment, the old craftsman was leading the way. Zhang Zong asked his father-in-law about the black stone while walking. He wanted to determine whether this thing was the coal he was looking for. Although it was old, his father-in-law still remembered this black stone. After all, their family background was mainly due to this kind of stone. Through his description, Zhang Zong was almost certain that the other party was dug out of the coal mine.

Baiyao Town belongs to Xinping County, but in fact it has already fallen out of the jurisdiction of Xianyang. However, in later generations, it was still a county under Xianyang City. The largest mineral deposit in Xianyang is coal. When Zhang Zong came to Chang'an to play in his previous life, he also stayed in Xianyang for a few days. He had seen with his own eyes many coal mines northwest of Xianyang, which is why he brought Xue Shao and the others here.

The father-in-law took Zhang Zong and the others to the western suburbs of the town. This is a low hill. Occasionally, you can see several porcelain workshops. In fact, these porcelain workshops were built on porcelain clay mines. Craftsmen dug out porcelain clay from the mountains, then made into porcelain, and then collected by merchants to transport them to Chang'an and other places.

Zhang Zong knew that porcelain clay was kaolin. In addition to coal, Xianyang also had many kaolin mines. However, he did not expect that in the Tang Dynasty, a ceramic industry had already formed here.

Zhang Zong and his friends walked along a deserted road to a valley. Although the road was full of weeds, they could vaguely see that the road must have been very wide and flat back then. After entering the valley, they immediately saw a broken wall. It was probably the ceramic workshop of my father-in-law's house.

Looking at the ruins of the workshop, the father-in-law seemed to be a little moved. Then he walked into this abandoned workshop with a familiarity. Everyone walked not far away. Soon several large pits appeared in front of him. The father-in-law pointed to the big pit and said, "This is the porcelain clay mine in the past. We used to take soil here, but unexpectedly, after digging several feet down, the bottom was covered with black stones, which was useless at all!"

Zhang Zong was also excited when he heard this. He immediately wanted to go down the pit to check it out. It would be better to dig out some black stones to check it out in person, but his father stopped him and said, "You don't need to go down. We have dug out a lot of stones before, and they are piled up next to it. I'll take you there and see!"
