Yin Wind Canyon is indeed the most suitable place for Su Che to practice, the people here are all at the third level of Qi cultivation, even if they have a numerical advantage, they can't pose a danger to Su Che.

So far, I have been in the canyon for more than 20 days, and I have experienced nearly 100 battles of all sizes, which can barely be called a hundred battles. It doesn't matter if he wins or loses, Su Che feels that he has indeed grown a lot, and he is no longer a junior rookie in combat. And he also vaguely felt that the cognition and mastery of his own strength had reached a higher level, and it seemed that he might have an epiphany at any time in the past few days, and that would be able to impact the realm of the middle stage of qi training.

In the Immortal Prison, it took two days for Luo Lianqiao to refine a furnace of 'Escape Pill', and today, it is exactly twenty days to refine ten furnaces, of which four furnaces are waste pills, which means that the success rate can be tentatively set at 60%.

There are so many waste pills, Luo Lianqiao's explanation is: The conditions in the prison are poor, far less complete than the alchemy facilities in Tianlu Peak, and the most important thing is that with the fire control method of real fire spirit runes and special incendiary materials, the firepower is very unstable, and the variables are quite large, and it is not easy to master. If there is a stable fire vein of the three-grade earth fire, the success rate of refining the Retreat Pill should be eighty percent.

His success rate in Heavenly Furnace Peak is this number, surpassing most of the inner disciples of Heavenly Furnace Peak, so he can claim to be a genius in alchemy.

This explanation is very reasonable, even if Su Che doesn't understand alchemy, he also understands that all aspects of the conditions in the immortal prison are indeed insufficient, and Lao Hei can also prove through mind reading that Luo Lianqiao is not lying, he really tried his best.

If you do your best, you can make up for the lack of facilities in the future...... So, Su Che rewarded Luo Lianqiao with thirty-six spirit stones, which could be used for him to cultivate normally for a month.

There are no underground spiritual veins in the immortal prison, and there is no heaven and earth spiritual energy, and the prisoners want to continue to cultivate and continue to improve their strength, for now, they can only absorb the pure spiritual energy contained in the spirit stone. Of course, Su Che could not provide spirit stones for nothing, and the prisoners could only get a certain percentage of rewards if they made contributions.

Spirit stones are just one of the ways to reward.

The Dan is a special type of pill, and only three pills can be produced in one furnace, and Luo Lianqiao has refined it into six furnaces, with a total of eighteen finished pills. Although it is difficult to buy Dundi Dan in the market, there is always an approximate price. Luo Lianqiao said that the cost price of a pill of Dundi Pill was less than twenty spirit stones, but it could be sold for a high price of two hundred spirit stones.

You can get ten times more violence, not only because it is very high and scarce, but also because with such an elixir in hand, at a critical moment, you can drill into the ground to save your life. This is a magical ability that only Jindan monks can master, so many monks in the foundation building period will not hesitate to buy the Escape Pill.

From this point of view, the market price of eighteen Retreat Pills was about three thousand six hundred spirit stones, so Su Che gave Luo Lianqiao a reward of one percent.

The proportion of one percent seems to be very low, but Luo Lianqiao can continue to refine the pill, and he will get a steady stream of rewards, which is enough for him to cultivate in the Immortal Prison. The premise is that the Hideaway Poison Ivy in the Yin Wind Canyon can be harvested inexhaustibly......

Somewhere in the canyon, Su Che took out a Retreat Pill, and today, even if he didn't encounter any danger, he couldn't help but want to try the magical effect of this pill.

The yellow-brown elixir melted in his mouth, and immediately a wonderful feeling flooded into his brain.

Bang!bang......

The earth pulsates, as if the heart of the earth is beating strongly......

"So it was, and the earth beneath our feet was alive. ”

Su Che had a vague realization, his mind moved, and the whole person sank into the soil layer silently. Miraculously, there are no holes in the ground.

Escaping the ground is not digging the ground, so it will not leave any traces on the ground.

Bang!bang......

Su Che shuttled freely underground, thick soil, huge rocks, and ores containing metal components would not form a barrier, just like a fish returning to the sea, free.

At this moment, Su Che's heartbeat actually resonated with the pulse of the earth, and the beating frequency tended to be the same, which was the privilege enjoyed by the children of the earth.

The medicinal power of a Retreat Pill lasted for a quarter of an hour, but before it was half an hour, Su Che had a flash of inspiration and shouted in his heart: "I understand!"

Then, without hesitation, he took out a magic sword, brushed and cut the surrounding soil layer vigorously, and all the soil and stones cut down were sent to the immortal prison......

In the immortal prison, Lao Hei knew very well that the master had reached the critical point of breaking through the realm after the accumulation of these battles, and at this moment, with the help of the induction of the pulse of the earth, he immediately had an epiphany, and it was estimated that he would soon begin to impact the realm barrier of the fourth layer of Qi training.

Su Che himself has an earth-based spiritual root, and although he has never cultivated a pure earth-based technique, at this moment, with the help of the temporary identity of the son of the earth, he can mobilize the incomparably vast earth qi around him to help him break through the level.

With the help of the power of nature, this is another layer of Sucher's understanding in terms of strength.

Bang!bang......

The heartbeat still resonated with the earth's pulsations, and a steady stream of earth qi gathered from all directions, slowly injecting into Su Che's body.

Earth Qi is also a kind of Heaven and Earth Aura, which is fused with the True Qi in Su Che's body, which makes the True Qi surname quality change. This is also a change of unintentional willow insertion, after that, if Su Che chooses to major in earth system exercises, he should achieve twice the result with half the effort.

Su Che had three spiritual roots of fire, earth, and wood, and originally, he was more inclined to major in fire-based exercises. There is no specific reason, but I think the fire spell looks more powerful.

In fact, there is no superiority in the Five Elements Spells, the difference is only in the cultivator's own factors, and different people may be more suitable for cultivating a certain line of exercises......

Lao Hei felt that it didn't matter at all which system of exercises the master cultivated, as long as he could continue to improve his cultivation realm, the master's advantage should be the immortal prison, not those factors in the conventional sense.

With the passage of time, the medicinal effect of the Escape Pill quickly passed, and Su Che's sense of the earth pulse disappeared, but it didn't matter, the earth pulse was equivalent to a leader, who had helped him master the method of absorbing the earth qi, and the continuous flow of earth qi was still converging towards him.

The true qi in the body slowly changed the quality of the surname, and when the characteristics of the earth-based true qi were already particularly obvious, and the body could no longer hold more earth qi, with a snap, Su Che's body shook, and he felt that a certain level deep in his body was suddenly washed away!

It is an extremely subtle feeling, indescribable in words.

"It's done!"

Su Che hurriedly took out an Earth Spirit Pill, swallowed it, and immediately refined it, producing a large amount of spiritual power, which was then transformed into a new True Qi...... It was as if the riverbed of Gangu had been instilled by the flood, and it was already the meridians and dantian of the fourth layer of Qi training, and it needed more True Qi to be filled.

Yes, the fourth level of Qi training, Su Che has officially stepped into the cultivation realm of the middle stage of Qi training.

......

He had been cultivating in the underground cave for three days and three nights, and had completely absorbed the medicinal power of an earth spirit pill, and Su Che had stabilized the realm of the fourth layer of qi training.

Before, it took five or six days to refine and absorb an Earth Spirit Pill, but after advancing to the middle stage of Qi training, it only took three days to fully absorb the medicinal power, which was the obvious difference after the strength was improved.

Moreover, the cave here is more than ten zhang deep underground, and after three days, there has long been no air, but Su Che does not have the slightest feeling of holding his breath, the reason for this is of course, because there is a small world within a radius of a hundred miles inside the Immortal Prison, which can provide Su Che with endless air, and it will not suffocate in any environment.

"Congratulations, master. Lao Hei said happily: "The original plan was only to reach the third level of qi training in half a year, and you have overfulfilled the task." ”

"Yes, this trip to Yinfeng Canyon is indeed very rewarding. The feeling of being promoted made Su Che's mood even happier.

"I think that's not all......

Lao Hei said mysteriously: "There is something I haven't told you, because I don't want to affect your concentration during this time. Now that you've advanced to the middle stage of Qi training, you'll be able to say it. ”

"Oh, what's the matter?" Su Che wondered.

"You've given the Yin Wind Rat three tasks: finding people, finding objects, and exploring secrets. Among them, finding people and finding things has been done quite well, but there has been no movement in the exploration of secrets. Lao Hei said: "A few days ago, the rat king of a certain group reported to me that there is a secret crypt in its territory, and the depth does not know the geometry, and even the Yin Wind Rats, who are the best at burrowing, dare not go too deep...... Master, I don't know, are you interested in going there to see?"

Su Che knew that there must be a reason for Lao Hei to ask like this, so he replied: "It seems that you are quite interested in there, so let's talk about the specific situation." ”
