"Yan Er is in charge, this matter... I can't do this! I have to agree to this, you see... Liu Shan said with an embarrassed expression.

"Then what are you waiting for, why don't you go and ask your alliance leader for instructions? It just so happens that we are going back to rest for a while, you will come and inform us immediately if there is news, do you hear?" Yan Qiu said with a look of course as an uncle.

"This... This... ！”

"Why don't you go now?"

"Alas!

After sending Liu Shan and the others away, the three fat men returned to the vein where Qin Tian was. At this time, Qin Tian was still practicing the "Bone Shrinking Technique", and as his cultivation continued to progress, he gradually gained a further understanding of human bones and muscles.

The muscles and bones of the human body have something in common.

Each muscle fiber has a certain gap between it, and the muscle fiber has good toughness, which makes it expand or contract within a certain range, so that the volume changes, becomes larger when expanding, and becomes smaller when contracting.

Bones also have similar properties, the density of human bones is not immutable, and the elderly are prone to osteoporosis, which is the result of changes in bone density. This shows that there are certain voids inside the human skeleton, and these voids can change under certain circumstances, so that the bones also have the effect of expanding and contracting like muscles, which is the basic principle of "Bone Reduction".

It's easy to say, but it's not easy to do. The so-called "it is difficult to train the bones by practicing the skin and flesh", the cultivation of bones is very difficult, and only when you reach the level of transforming strength can you come into contact with some internal strength exercises related to the cultivation of bones, and these exercises are all the top exercises of various sects. Therefore, "cutting the hair and washing the marrow, and being reborn" will be considered to be the highest level of martial arts cultivation.

In fact, strictly speaking, the "Bone Reduction Technique" has not reached such a high level, because it is only an applied exercise, and it does not have the anti-heaven function of comprehensively improving the human body's physique like the "Three Cleansing Records", so its cultivation difficulty is correspondingly not so great.

It is mainly through the fine control of internal strength, first to achieve the fine control of human muscles, and then through the intramuscular contraction and positioning stimulation of internal strength to promote bone contraction or expansion, so as to achieve the effect of bone shrinkage, reduction and even expansion.

After understanding the principle of the Bone Shrinking Technique, Qin Tian's cultivation was on the right track. Through this period of cultivation, his ability to control his muscles has been greatly improved, and the flexibility of his body has reached a very high level.

He found that he was able to contort parts of his body to an exaggerated level like the world's top jiu-jitsu athletes.

This kind of promotion has a great effect, Qin Tian now has a little understanding of the realm of Indian yoga masters, and this extreme control of the body can make him have more room and choice to play and occupy a more advantageous position when fighting against the enemy.

However, it will take a while to truly refine the Bone Shrinking Technique, and what Qin Tian has to do now is to shorten this time as much as possible.

Seeing that Qin Tian had finished his cultivation, the fat man Yan Qiu, Li Ze, and Liu Hai immediately surrounded him and told Qin Tian their idea of going to the No. 2 mining area.

Qin Tian pondered slightly, and then nodded in agreement: "Your ideas are good, naturally you can't miss the opportunity." It doesn't hurt to go check it out!"

Just as Qin Tian was discussing with the fat man, Liu Shan also returned to the headquarters of the Mining Alliance to meet the alliance leader Zhong Li Mo. After finally Li Mo learned about this, he went to Ram Shen's room to discuss with him.

"What do you say Qin Tian is planning to do?" asked Zhong Li Mo with a frown.

The behavior of the fat man Yan Qiu and the three of them wandering around had already made him a little unhappy, and now they actually proposed to go to the No. 2 mining area, such a request was even more excessive. Could it be that Qin Tian and the others had any other purpose in coming to this cave, otherwise how could they make such an unreasonable request?

"I don't know what kind of medicine is sold in the gourd of these Qin Tian people, but we don't need to know. Ram Shen pinched his short beard and said.

"Oh, what do you mean by that?"

"The Ma Jun guy has news, and the time for action is not far off!"

"What?" "The huge bull's eyes flashed with excitement.

"That... How the hell is going to deal with this matter?" calmed down his excitement a little, and finally Li Mo regained his composure.

"Let them go if they want to! It's better if they go and don't come back, so we'll have less trouble, won't we?"

"Then let's do it!"

Zhong Li Mo thought about it and finally agreed to this suggestion, so he called Liu Shan and asked him to take Qin Tian and them to the No. 2 mining area.

Liu Shan didn't dare to disobey the order of the alliance leader, so he went to the ore vein to find Qin Tian and the four of them, and took them to the vicinity of the forbidden area of a mine, passed through a hidden and narrow mine tunnel, and came to a small room.

It's like a transit station, and it's spacious and guarded by special personnel. I don't know what Liu Shan said to the guards, the guards glanced at Qin Tian and the four of them suspiciously, and then they were allowed to pass.

There were three different mine crossings opposite the room, and Liu Shan led Qin Tian and the four people into the leftmost mine crossing. This mine road is very narrow, and people can only pass one after another with their heads bowed and bent over, which is very inconvenient to walk. Moreover, the mine road was very long, and Qin Tian and the others walked for nearly two hours before they came to the end.

At the end of the tunnel, there is also a room that resembles a transit station, where it is still guarded by the Mine Alliance. Judging from what we know so far, the Mining Alliance attaches great importance to these rooms, and this should be an extremely important pass for them.

Qin Tian didn't talk nonsense along the way, just silently followed Liu Shan all the way. It wasn't until he crossed this pass and came to the No. 2 mining area that he grabbed Liu Shan and asked, "There were three passages in the previous two rooms, is it possible to reach some other places through them?"

Liu Shan glanced at Qin Tian cautiously, and then said worriedly: "Big boss, I won't tell you, the villain really doesn't know about these things! If I hadn't participated in the construction of this mine road now, I wouldn't have known that this place could be connected to the No. 2 mining area." The other mine villains didn't participate in the construction, so the villains don't know where they lead?"

Liu Shan secretly glanced at Qin Tian and saw that he was not angry, so he boldly said: "It is forbidden to talk about this matter within the Mining Alliance, so the people who know about it are only those who participated in the construction and the high-level leaders of the Mining Alliance. In fact, the villain also knew privately that the other passages most likely to lead to the No. 1 mine and... ”

Liu Shan pointed to the top of his head as he spoke, Qin Tian nodded knowingly, and then put him back.

"Liu Shan, this guy should still know a lot of things, why don't you leave him and ask him clearly?" The fat man saw that Liu Shan looked like he was running for his life, so he didn't fight anywhere, making them seem to be fierce and evil, which was really unpleasant.

"Forget it, he's said enough, so why bother him?

Qin Tian waved his hand, and then took the lead in walking towards the depths of the No. 2 mining area.

As soon as they entered the No. 2 mining area, the fat man Yan Qiu and the three of them immediately became excited, and their great cause of looting could be carried out again.

Before Qin Tian could greet him, the three of them were scurrying around again, Qin Tian could only shake his head helplessly, and followed them all the way.

But the good times didn't last long, and the three of them were surrounded in a wide vein before they could search the mine road.

"Hahahaha! Where are you spies going?"

A smug laugh sounded in the mines, and then teams of miners in the adjacent mines ran out neatly and surrounded Qin Tian and them.

The fat man Yan Qiu was a little unexpected, and after he and Li Ze glanced at each other, they silently waited to see the other party's next move.

The one who led people to surround Qin Tian and the four of them was a big stunned boy who was more than two meters tall and as strong as an iron tower. There was a thick stupidity on his childish face, and as the saying goes, this person looked a little stunned!

Faced with such a figure with a great contrast in age and body shape, Qin Tian couldn't help but mention a little interest, thinking that this person was Liu Shan's so-called two stunned iron pillars!

Tie Zhu was training his boys hard today, but he didn't expect someone to report to him that he had found a few suspicious spies. This made Tiezhu, who had been holding back for a long time, finally find a chance to vent, and after not doing it for too long, he only felt that the bones all over his body were itching uncomfortably.

"Stand still, you spies, and obediently come and die!" shouted Iron Pillar as soon as he came.

"Don't get me wrong, we have no malicious intentions!" Qin Tian didn't want to clash with the biggest force in the No. 2 Mining Area at will, so he asked politely.

"Don't talk nonsense! What misunderstanding is not misunderstood, let's fight first!"

After saying that, Tie Zhu couldn't help but say that he took the lead and strode towards Qin Tian and the four of them, looking at the posture that he would definitely not give up if he didn't fight.

"I'll meet you!"

Seeing that Tie Zhu was so unreasonable, the most unreasonable fat man among Qin Tian's four people couldn't sit still, and he rushed up to teach this stunned boy a lesson.

"Good time!

As soon as Tie Zhu saw that someone took the initiative to fight, he immediately laughed happily, and the whole person strode towards the fat man like a meteor.

Seeing this, their subordinates quickly retreated one by one to keep a distance from him, so as not to be seriously injured by the overexcited boss.

So a huge iron pillar collided with an equally huge mountain of meat, and only to hear the sound of "bang!", the two of them took a few steps back almost at the same time before they stood firm.

The result of such a collision was beyond the expectations of the two of them, and they looked at each other, and they saw surprise in each other's eyes. However, this surprise was immediately abandoned by them, and the two of them rushed towards each other almost at the same time, and the violent collision was staged again, and the result was no different.

In this kind of face-to-face collision of pure strength, Tie Zhu and the fat man were actually unable to endure anyone.

For such a result, Tie Zhu was unacceptable in his heart, because what he was most proud of was his innate brute strength, he was a typical innate divine power, and it was precisely because of this that he was favored by the master and learned a lot of skills.

And now that this hateful fat man in front of him can actually compete with him in strength, how can he accept this?

"Ahh

After the iron pillar roared, his extremely strong body suddenly burst into muscles, and the muscles of his entire body swelled up as if he were blowing, making him as terrifying as a troll descending into the world.
