In the immortal prison, Lao Hei held a bronze gourd in his hand, opened the stopper, and shouted at the spirit of earth fire in the fire pool.

The Spirit of Earth Fire hesitated slightly, as if it was ruthless, and with a hula, it turned into a ball of flames, which was sucked into the bronze gourd.

It didn't take long for the bronze gourd to shimmer and look much more agile. There was no need for Lao Hei to explain, Su Che also guessed that it must be the spirit of earth fire that fused the basically abolished spirit inside and turned it into a new spirit of the machine.

As soon as the machine spirit is alive, the whole magic weapon is also alive.

From now on, just absorb all kinds of flames into the gourd, and its power will slowly manifest. At the moment, even Lao Hei can't be sure what functions it has.

Su Che thinks that it is also a lot of fun to gradually explore the growth space of a magic weapon. For himself, the most important Immortal Hell Pagoda is even more so.

Next, it's time to study the statue of the purple jade villain.

However, Lao Hei was puzzled: "Master, I can only be sure that this faceless statue is a special type of magic weapon, and it is estimated that its grade is a little higher than the spirit grass planting box and bronze gourd." ”

Suche helped him and said, "But ......"

"However, I have never figured out what its purpose is, and I hope that after you have built the foundation, you will go to the library and look up the relevant ancient books, maybe you can find the answer, or give me some inspiration. ”

"No problem!"

Su Che shouted happily: "Then go to bed and build the foundation tomorrow!"

Plop, lie down and fall asleep.

Immortal cultivators have an advantage, that is, there is no insomnia, even if they encounter troublesome things, they can quickly enter the state of emptiness without distractions, and immediately fall asleep, which is all practiced by meditation without white or black.

After a night without words, after waking up the next day, Su Che didn't make any preparations, and he didn't even need to go out to the cave to adjust his mood, and directly started retreat.

There is no exact data on how difficult it is to build a foundation. Theoretically speaking, the factor of innate aptitude is the most important, and those Tianling Roots, that is, those Tianzong talents who belong to the surname Linggen alone, do not need to take Zhuji Dan, and they all have a success rate of more than seven or eighty percent.

It is said that Su Che has a medium qualification, not only to take the Tsukidan, but also to be assisted by other pills that can increase the chance of success, such as the Dacheng Dan...... In addition, factors such as the right time, place, opportunity, perception and so on will also have a great impact.

In the entire cultivation realm, the base number of Qi cultivation stage cultivators at the bottom is very large, but the people who can successfully build a foundation are often one in a hundred.

Taking the medium-sized Xiuzhen sect as an example, the head of the sect is the Jindan period, and there are more than a dozen elders in the foundation building period below, and they can control the fate of tens of thousands of disciples in the Qi cultivation period.

Even so, it is extremely difficult for a person with a poor spiritual root to enter a medium-sized sect.

From this point of view, the difficulty of building a foundation is so great, why would Su Che be so hasty and so hasty in retreating and building a foundation?

The answer is very simple, that is, because Su Che felt that the previous accumulation was extremely deep, and there was no suspense in building the foundation this time, and the success rate would be greater than that of the Heavenly Spirit Root.

Hold on to it, no need to wait!

Su Che sat cross-legged on the ground, took a Tsukidan, and calmly began to meditate. As for what Dacheng Dan is, just like Venerable Xuanji said, there is no need to take it at all, and it is a waste to take it.

Zhuji Dan has two functions, one is to strengthen and transform the physical strength of the Great Perfection Cultivator of Qi Training, so that the meridians and dantian have the qualifications to carry the True Yuan, otherwise, the surname of the True Yuan is tantamount to a corrosive poison for the Qi training period.

The second function is to trigger a qualitative change in the true qi in the body, which is already in a saturated state, from a gaseous state to a liquid state, so that it can become a higher level of internal energy 'true element'.

Su Che's physical strength has already been strengthened to the pinnacle of the current realm, and it can be said that the first role of the foundation building pill has been wasted, so Su Che's foundation building process will also save more than half of the time compared to others.

When Yuqing retreated and built the foundation, it took more than a month, while Su Che estimated that it would only take ten days, and it was about the same.

Sure enough, sixteen days later, Su Che slowly finished his work, opened his eyes, and said to Lao Hei in his heart: "Okay, it's over." ”

"Congratulations to the master, you have successfully built the foundation!" said the old black grin.

A small cloud of crimson liquid was quietly suspended in Su Che's dantian, this was the fire system true element that had just been condensed, and its process was not effortless at all, it was much smoother than the rush in the qi cultivation stage.

This is because Su Che's previous savings were too rich, and the factors that others lacked, he had accumulated to the top, and they were already such conditions, if he couldn't succeed, in addition to the evaluation of waste, he had to add a sentence of 'unlucky' to describe it.

"The foundation has been built, and the foundation has been built so easily. ”

At this moment, even Su Che himself was in a trance, and couldn't help but ask stupidly: "Old Hei, tell me, am I still in the Xiaomi Immortal Realm, and I was cast a hallucination spell by the guardian power of that holy land, and everything that happened at this moment is fake, it is all my dream?"

"Yes, master. Lao Hei sighed: "Actually, even now, you have been sleeping in the Xiaomi Immortal Realm for more than thirty days, and if you count it, those surviving treasure exploration disciples have already opened the enchantment and gone out, and you can only wait until fifty years later, when the next time you open it, you can ...... again."

"!"

Su Che scolded with a smile, but did not leave the customs immediately, but swallowed a six-rank pill and continued to cultivate.

It's only been sixteen days, and if this is out, it will make many people think it's incredible, and it would be too high-profile. It's better to stabilize the realm honestly, and then go out to show off in two months.

Moreover, there is only a pitiful small group of true yuan condensed in the dantian, and the meridians of the whole body are empty.

The feeling of being empty and fluttering is extremely unsteady, and it must be filled up before Su Che will feel confident.

Before the foundation was built, under the influence of the Immortal Hell Warm Current and the Black Stone Clear Stream, it would take a whole day for a Six-Rank Pill to absorb and transform, but now, it could not last for five hours, and the medicinal power would be exhausted.

Su Che secretly said in his heart: "With this kind of cultivation method, no amount of pills is enough." Fortunately, that Shanggu Town Mountain Talisman can be exchanged for a large amount of pills given by the sect, otherwise, I just rely on my own ability, and I don't know how much energy it will take......"

"Yes, master, everything else is outside the body, for now, getting enough pills and improving cultivation as soon as possible is the fundamental way. Lao Hei also said: "Otherwise, no matter how much spiritual treasure you are given, your cultivation is not enough, and you will not be able to control it." ”

"That's right. ”

Another pill went down to his stomach and continued to cultivate.

After more than 30 days of uninterrupted penance, Su Che's cultivation realm was stable in the initial stage of foundation building, and the true yuan in his body was full, reaching a saturated state.

was about to get out of the customs, but he didn't want to, so Lao Hei mentioned a big thing.

For Sucher, this is definitely an unparalleled event!

"Master, these days, in order not to disturb your cultivation, there is something I haven't told you all this time, and it's not too late to tell you now. Old Hei said in a deep voice.

"What's the matter, tell me. Su Che was still a little unimpressed.

"On the tenth day after you successfully built the foundation, the Immortal Hell Pagoda automatically showed a way to open the second layer. Old Black said in a solemn tone.

"What?"

Su Che was shocked: "The second layer of the Immortal Hell can be opened?"

"Yes. Old Black confirmed.

"Quick, let's talk about it......" Su Che's emotions were extremely excited.

Immortal Prison! Immortal Prison! Immortal Prison is his own foundation, and Su Che attaches great importance to any change in Immortal Prison.

It was precisely because he guessed this that Lao Hei would postpone informing him of this matter, lest the master mess up his state of mind and affect his normal cultivation.

"The method of opening automatically appeared in my mind. Lao Hei said: "If you want to open the second layer of the Immortal Hell Pagoda, you must meet several conditions. ”

"Hmm. Su Che responded, in fact, he had already guessed that certain conditions needed to be met to open the second layer, because, when the first layer was opened, it was necessary to capture three creatures of demons and demons.

Lao Hei elaborated: "The first condition, you have already met, that is, the master of the Immortal Prison must reach the foundation building stage of cultivation. ”

"Second, you need to provide enough energy to the Immortal Prison. Actually, that is, you need enough spirit stones, and I estimate that at least one million spirit stones will be needed. ”

One million lower-grade spirit stones sounds terrifying, but in fact, when converted into high-grade spirit stones, a hundred is enough. Su Che silently estimated that the nearly 100 high-grade spirit stones that he had picked down in the underground hall of Xiaomi Immortal Realm, even if he couldn't meet this requirement, he didn't need to make up too much.

"The third one requires 800 earth demons and 3,000 yin souls. Lao Hei continued: "I estimate that the caste of the second layer of the Immortal Prison is related to the cold things. ”

"Sounds like it should be. Su Che nodded silently.

Three thousand yin souls are easy to explain, that is, three thousand evil ghosts, they are easy to get in the cultivation realm, and they don't need to be arrested in person, and they can buy a lot of them when they go to the cultivation market on the demon cultivation territory.

However, eight hundred earth demons are difficult to find above the surface, and Su Che needs to go to the underground world to fight against the underground demons.

The Underworld Demon Race is divided into four levels: Earth Evil, Yaksha, Shura, and Great Asura.

The strength of the 'Earth Evil' is similar to that of the human Qi cultivation period monks, the strength of the 'Yaksha' is similar to that of the human foundation building stage monks, and the 'Shura' is the Jindan stage, Su Che has already seen one, and he almost died in his hands.

Further up, it is the 'Great Shura', which is equivalent to the Yuan Infant Monk, however, there are not many Great Shura in the entire underground world, so they will be suppressed by humans in the depths of the earth, and they will not be able to emerge for hundreds of thousands of years.

"It's fine. Su Che breathed a sigh of relief: "It's just a geocharisma, I'm already in the foundation building period, and it's not too difficult to capture the geosha." It seems that the three conditions for opening the second layer of the Immortal Hell are relatively easy to meet. ”

Unexpectedly, in the immortal prison, Lao Hei replied shyly, and pleaded in a low voice: "Master, did I say that there is no fourth article?"
