Soon after Xiao Liuzi bought the medicine, he became busy with Lin Jue. Half an hour later, all vents and the passage dug by xiaoliuzi were completely blocked.

"All right, you go to the monitor outside and see. I'll come out immediately after I make a fire!" Lin Jue carried the Dan stove to one side and then put the herbs into it. It seemed that there was no order and attention at all. After seeing the flame rising, Lin Jue also quickly left the underground base and blocked the entrance and exit of the underground base.

"Minister, what are you doing?" Dong Xingwen asked when he saw Lin Jue coming out.

"Let's go back and have a look!" Lin Jue smiled and said, "as long as there is a secret way, no matter how hidden the secret way is and how good the burial method is, it must have a wind breath!"

"After all, it is a movable existence. In that case, it can't fit so tightly!"

"But the water can't get in!" Xiaoliuzi said.

"Indeed, I didn't expect that this trace should fit so tightly that even water can't penetrate!" Lin Jue nodded: "so, I changed a way!"

"Yes..."

"Look!" Before Xiao Liuzi finished, Xuetu pointed to the monitor and said, "it's smoke!"

Soon, I saw the Dan stove lit by Lin Jue, which had been filled with medicinal materials, suddenly burst out bursts of white smoke and went in all directions.

"Is that ok?" The sixth son looked at Lin Jue and asked.

"This smoke, or a kind of Qi, is more appropriate!" Lin Jue explained, "it doesn't work. It's a gadget I made when I was young."

"This Qi is the essence of medicinal materials. It is pure and natural. It is very light and turbid. It can be seen by the naked eye because it is turbid. However, it is very light and floats in the air, even several times lighter than the air!"

"However, the volatilization speed is too fast. When encountering the wind, it will quickly blend with the wind and finally disappear. Therefore, if we want it to stay below, we can trap it for a while just after we block all the entrances and exits."

"I see!" Xiao Liuzi nodded after hearing this, indicating that he understood.

In tight things, it also needs a gap or enough space to open and close.

Now it's late autumn, and the autumn wind is blowing outside all the time. When the space below reaches a certain degree, these "Qi" will begin to find their own outlet!

In this way, we can find the real secret way!

At that time, with the wind blowing in, the "Qi" will quickly disappear, which will be more obvious.

As for why there is wind in the secret passage... Is the secret passage sealed and blocked? Naturally, there is a need for vents.

Here, it doesn't matter if you don't.

Because Lin Jue only needs to determine where the "Qi" of the underground base will flow after it is full, which is enough.

Time, minute by minute. Due to the huge space, it took more than half an hour to fill up gradually.

At this time, people also saw the flow direction of "Qi" from the monitor. Although it was very weak, it was clear from the monitor that it was gradually twisting after it was full.

"I found it. I'm sure it's where we dug!" Several people looked at each other and nodded.

"Open the windows and doors and let the wind in!" Lin Jue looked at Xiao Liuzi and said, "I'll start alchemy for about three hours. Then you start to dig deeply. I'll look at where this guy came from. He's hiding so deep!"

"All right!" Xiaoliuzi nodded.

Once the location is determined, it will be much easier to do next. Next, just dig all the way. It seems better if you happen to meet the opposite party who is planning to come up.

Unfortunately, from the past few times, it seems that the other party does not intend to come up during the day.

In that case, they had to dig down by themselves.

Although I believe that there should be a mechanism to open the secret passage in the underground base, it's a pity... I can't find it at all. Neither Qin Wei nor Lin Jue can find their attainments, so they can only use the stupidest method.

After all, when a person hides something, a thousand people can't find it. Perhaps the most stupid way to waste time is the most effective!

Soon, when the autumn wind blew into the underground base, the "Qi" dissipated rapidly at a speed visible to the naked eye, and disappeared after only a few breaths.

"It seems that the location is right. It's here! It's just... What mechanism is it? It's really puzzling!" Lin Jue took the people down and looked at the ground they had planed: "it can isolate internal power. The tightness can't even penetrate the water. It's really curious!"

"Then let's prepare the tools first!" Small six sons several people openings way.

"Well, you go first. I only need to warm the fire this time. I don't need your help!" Lin Jue nodded, then came to a corner carrying the Dan stove and began to prepare herbs.

This time, Lin Jue thought for a long time. Now the auction has entered the climax stage. The third-class pill must be useless.

Even if Lord Lin can practice third class and ninth grade, it's not worth wasting this effort at all. In that case, it's better to refine more than sixth class pills.

After all, even if it is a third-class pill, it is only a third-class pill, which can't be comparable to a sixth class pill!

It is worth saying that since the auction that day, people in the whole martial arts world have known the grade of pills. Almost everyone who buys and sells pills will ask how many pills are these!

And no longer like before, ignorant to buy any 369 class pills.

Because of the sudden incident, many stores didn't respond, and some people took the opportunity to find a lot of cheap. After all, after the grade things leaked out, now the whole pill industry hasn't given them an accurate pricing!

Although it won't lose money, it's certainly not as full as before.

Lin Jue thought about it and finally thought of a sixth class pill according to his existing materials!

By means of his alchemy, he is confident that at least he can be more than six grades and five grades! At this point, Lin Jue had to lament the infinite benefits of his internal power.

Whether it's his own recovery speed, healing, or alchemy and pharmacy, the reason why Lin Jue has this natural advantage is that he has a special internal force, which is like a panacea.

The most intuitive feeling is that if the success rate of other people's alchemy is 50%, and the success rate of refining more than five pills is 10%, then Lin Jue's success rate is at least 70%, and nine pills are also 30%!

If you simply refine the third grade and ninth grade, the success rate of Lin Jue's Alchemy can even reach a certain level.

The sixth grade pill he refined this time should be an auxiliary pill. Although it is an auxiliary pill, its effect can not be ignored.

The name of this pill is very simple, even a little earthy. When I was young, in order to polish my body, old man Yao developed it... Body strengthening and bone strengthening pill!

The use is simple and clear. For example, the name one can strengthen the body and bones.

Often this kind of pill is used to assist external martial arts practitioners. After all, since they came into contact with martial arts, they need to constantly polish their bodies and bear the hardships that many people can't bear.

In this process, taking this kind of pill can get twice the result with half the effort.

Therefore, this kind of pill is widely loved in the circle of external skill practitioners!

It's just a pity that there are too few people practicing external skills, and there are even fewer people who can achieve success. Therefore, although this pill is popular, its audience is very small.

But Lin Jue has no worries in this regard

Lin Jue was deeply relieved when he threw the last pair of sharp sword teeth, tiger tooth tips and gold silk blood into it.

"If it weren't for these materials, it wouldn't be possible to refine them!"

Lin Jue sighed at the thought of the man who traded with many strange animal corpses at the auction. For a martial doctor, it's just countless treasures! It's just a pity that even if the ghost city needs itself, it will never disclose each other's identity to itself.

After all, this involves the foundation of the ghost city. If you tell yourself, you will break the rules of the ghost city for thousands of years.

Lin Jue didn't think he had such great ability, so he could only shake his head sadly.

Saber toothed tiger, a strange beast, has long been extinct. And its tooth tip is the hardest part, which can easily penetrate any object, almost without disadvantage.

The golden silk blood is also the essence blood of the exotic golden silk leopard. It is said that after killing the Golden Leopard, the warrior directly smeared the blood essence of the Golden Leopard on the body, and then practiced, which can accelerate the improvement of skin strength and flexibility of muscles and bones.

Later, it was discovered by martial Taoist doctors that this method was too rough, so there was later research, and finally it became one of the materials of pills.

These two things are precious and precious, neither precious nor precious. Because if it's not necessary, no one will buy it. Maybe no one cares about it for decades.

But if you say the price is low, it's impossible. Both kinds of monsters are extinct, and even if they survive, their strength may not be subdued by ordinary martial arts masters. Who can use them to refine pills?

But when he was young, Lin Jue did see the complete skeletons of two strange animals. Otherwise, he wouldn't take this pill as sugar beans.
