The people of Zhongli Mo soon came to exchange the ore, and the leader was an old man who looked like a butler. Judging from his appearance, he was at least fifty years old, and it was a novelty to see such an old man in this harsh underground mine.

Qin Tian still clearly remembered that Liu Shan had told him that the old people and children were basically dead in the first two years of mining in the mine, so how could there still be old people here?

Although Qin Tian had a trace of doubt in his heart, he remained silent, just secretly observing this person.

The old man seemed to be very good at dealing with people, and as soon as he came, he said to Qin Tianzuo: "I wonder if this is the master of Qin?

"Oh, do you know me?" Qin Tian was a little surprised, he raised his eyebrows and asked rhetorically.

"The leader of the Zhongli Alliance specially told the old servant to do a good job of exchanging ores, so the old servant learned a little about the affairs of the Qin Da family from the alliance master. In the future, I will be personally responsible for the exchange of the old servant, and if the master of Qin has any other requirements, you can tell the old servant. ”

The ram servant behaved very respectfully, as if he could agree to any request made by Qin Tian, which made Qin Tian can't help but be a little interested in his identity.

However, Qin Tian didn't show his thoughts, but looked at him seriously, then pointed to the ore on the ground and said, "Since the Lord of the Zhongli Alliance has asked you to be in charge of this matter, then please trouble Mr. Ram to help us exchange all these ores, right?"

The ram servant looked at the piles of ore on the ground, and then frowned slightly and asked, "Do you want to exchange them all?"

"Yes, all of them! Replace them all with food!" Qin Tian nodded.

"Don't hide it from the Great Master Qin, your ores are all excellent black iron ores, which are much more precious than ordinary ores. This amount of ore is enough to exchange for a lot of food, and even for some other things, such as wine, medicine, etc. I wonder if the big boss needs anything else?" the ram servant looked up at Qin Tian seriously, and then patiently explained to him.

"What type of medicine do you get in exchange?"

"There are only some ordinary wound medicines, precious medicines that they can't provide to us, if the big boss wants it, the old servant can help you mobilize some. The ram servant introduced Qin Tian one by one.

"Well, then you can help me change some medicine, and all the rest for food!" Qin Tian thought for a moment before he said to the ram servant.

"Okay, I'll arrange for someone to bring things over right away. It's just that I don't know when the big boss plans to exchange it next time? The ram servant readily agreed, and did not forget to make an appointment with Qin Tian for the next exchange.

"Next time you come back in half a month! we have enough food to last a long time, and we don't want to be disturbed too often. Qin Tian said casually.

"Then in half a month! If the head of the Qin family changes his attention, he can also let someone notify the old servant, and the old servant will come when he receives the news. The ram servant did not hesitate to do his work, and he had the medicine and food brought in while arranging for the ore to be carried away in baskets.

It can be seen that the ram servant is obviously very familiar with this kind of thing, and it is very likely that he is responsible for the transaction between the mining alliance and the horse army.

The food brought by the ram servant was neatly placed in the basket, and these foods were basically foods that could be stored for a long time such as flour cakes, although the varieties were single but relatively real, and the medicines were small packages of medicinal powder, and Qin Tian couldn't recognize what the specific medicine was.

After the things were put away, the ram servant was busy arranging for his men to carry the ore, while Qin Tian picked up a dough cake and ate it.

The ram servant saw Qin Tian eat the dough bite by bite, and a trace of inexplicability flashed in his eyes, but he quickly returned to normal. He saw that his subordinates were working in an orderly manner, so he said to Qin Tian: "Master Qin, if there is nothing else, the old servant will leave first?"

"Old gentleman, please take care of yourself!" Qin Tian glanced at the ram servant and nodded.

The ram servant arranged the work of his subordinates and then left first, watching the figure of the ram servant gradually disappearing into the mine, Qin Tian's eyes flashed and immediately returned to normal.

In fact, Qin Tian didn't really swallow the dough just now, but was acting for the ram servant, in fact, he put it into the storage ring the moment he put it in his mouth.

The fat man Yan Qiu was very excited after getting the head token, this was the first time he had seen such a magical treasure in his life!

He kept studying the token as he touched it, and he found that the token was like a sophisticated mineral detector, as long as there was a precious ore like balaite around, then it would emit a light reminder, and the higher the purity of the deposit, the brighter the light it emitted.

The fat man Yan Qiu took Li Ze and Liu Hai along this mine road all the way to the underground, and on the way they found as many as three veins of dark iron ore. The purity of these three veins was slightly worse than the place where Qin Tian was located, which made the fat man who wanted to find the high-purity veins very unwilling. After carefully marking them, they continued to explore the depths of the tunnel.

In the process of continuous exploration, the fat man Yan Qiu discovered an interesting phenomenon, he found that the token was actually able to absorb internal strength, and after absorbing internal strength, its detection distance became much larger. This unexpected discovery made Li Ze and Liu Hai couldn't help but grab the token and try it in person, and the three of them had a lot of fun for a while.

This magical token seems to be like a bottomless pit, no matter how much internal energy is entered, it does not feel like it has reached the limit, but the detection distance will be further increased.

With this unexpected discovery, the three fat men were even more excited, and they continued to explore the ore veins while constantly trying to develop new functions of the token.

As the three of them went deeper, the tunnel became narrower and narrower, and the tunnel was coming to an end. Along the way, the fat man and the others found as many as six veins, and they all carefully marked them so that they could dig again in the future.

However, since the purity of these veins was not as good as that of Qin Tian's place, the fat man still insisted on continuing to search deeply, and he would never give up until he found a vein of higher purity!

The fat man's persistence finally paid off, and as they approached the end of the tunnel, the token suddenly glowed a hazy white. As they continued to go deeper, the tunnel was so narrow that it could only accommodate one to move slowly, but the light on the token became brighter and brighter, as if it was constantly urging them to go deeper.

Just when Yan Qiu and the others saw the last end of the mine, the light of the token was already as bright as the bright moon, almost illuminating the narrow mine.

The bright light made Yan Qiu, Li Ze, and Liu Hai all look straight, and the gray-brown rock on the mine wall in front of them was clearly recognizable, and there was no trace of the shadow of the dark iron ore on it. Could it be that behind this ordinary rock wall, there is a vein of ore that is much purer than Qin Tian's?

The light of the token was many times brighter than what he saw on Qin Tian's side, so the purity of the veins behind this rock wall must be very amazing.

This unexpected discovery completely stunned the three fat people, and a huge sense of happiness instantly enveloped the three of them, making them lose the ability to react for a while.

It wasn't until a long time later that Liu Hai took the lead in recovering, he glanced at the ordinary rock wall nostalgically, then turned his head to Yan Qiu and Li Ze and said, "I'll go and inform Qin Tian!"

Yan Qiu swallowed his saliva hard, and then replied with a smile: "Hehe, you go! It's good to have me and Li Ze here!"

Li Ze didn't speak, just nodded vigorously, and his eyes were reluctant to leave the rock wall for a moment.

Liu Hai saw that Yan Qiu and Li Ze looked obsessed, so he shook his head and turned around and walked towards the mine road where he came.

After the bangs left, Yan Qiu and Li Zecai slowly came back to their senses, they glanced at each other and then shouted almost at the same time: "Dig it!"

The fat man Yan Qiu and Li Ze picked up the shovel and dug it against the rock wall, and under the huge attraction of the high-purity black iron ore, the two of them were full of energy, and it didn't take long to dig out a space here that could be used by several people at the same time.

The thickness of the rock wall in front of them was beyond the expectations of the two of them, and the two of them dug several meters deep and did not find any ore. If it weren't for the fact that the light of the token was getting brighter and brighter, they all thought that they were not delusional.

Just as the two of them were sweating profusely, Liu Hai took Qin Tian into this slightly narrow space.

Qin Tian was also shocked when he saw the token that emitted a dazzling light, although he had heard Liu Hai say this situation, he couldn't help but be a little surprised when he really saw it. How pure does the iron ore here have to be to make the token shine so brightly?

Yan Qiu and Li Ze, who were already exhausted, immediately became happy when they saw Qin Tian and Liu Hai's arrival, and they could finally take a rest.

Qin Tian and Liu Hai took over the work of Yan Qiu and Li Ze, and continued to excavate the rock wall, and with the continuous efforts of the two, the true face of the ore was finally revealed.

Qin Tian picked up a piece of dark iron ore, but found that its purity was not much different from the previous one, Yan Qiu, Li Ze, and Liu Hai also came over, and everyone was a little puzzled by this phenomenon.

Qin Tian looked at the ore in his hand, then at the token that was still shining brightly, and then turned his head to look at the rock wall almost at the same time as Yan Qiu and the others.

"The good stuff should still be in there!" the fat man affirmed.

"I think so too!" Li Ze also nodded in agreement.

"So what are you waiting for?" the bangs were more direct.

"Keep going!"

After Qin Tian finished speaking, he threw away the ore in his hand and picked up the shovel again and walked towards the mine wall, and Liu Hai also quickly followed.

As the excavation continues to advance, the purity of the ore produced is also constantly improving, Yan Qiu and they no longer have the heart to collect these peripheral ores, they just want to know, how pure can the purest ore in the center be?

The higher the purity of the ore, the greater the difficulty of excavation, Qin Tian and the four of them took turns digging in batches to ensure the progress, and after digging for nearly a whole day, they actually dug through this rock wall unexpectedly and came to a natural karst cave.

The scene in the cave made Qin Tian's four people so shocked that they couldn't close their mouths, and the silver spar on the cave wall that was radiating a charming light like a sky full of stars shook their eyes.

"Millennium Xuanjing!" Qin Tian couldn't help but shout.
