Su Mo frowned, this guy obviously didn't have this kind of Danfang, and he still had a tone that he didn't admit to death!

A day passed in a blink of an eye, and Dao Nu said proudly: "There are too many Danfangs, it's too difficult to find, so give this to you." ”

Su Mo saw that this was an eight-grade pill recipe, and there were more than a hundred kinds of medicinal materials in it, and he glanced at the pill unconsciously, thinking that he had never refined such a difficult pill.

And Dannu said that he was very helpless, "This thing is different from other pills, and it has to be spread by the air, and at the same time, it does no harm to cultivators! Therefore, the medicinal materials required are a little terrifying, and the difficulty of refining is not low! But this is also the only kind that you can reluctantly refine." ”

This Dan is called Soul Devouring, and it can only have an effect on fourth-order demonic beasts, Su Mo looked at Dan Fang a little stunned, refining is no problem, but the consumption must be huge! But he still walked out of the room and handed the medicinal materials he needed to Zhang Xingtian.

"To tell you the truth, this pill is the only one I can barely refine at the moment, and the consumption is not small! It's just because my strength is insufficient, but it's more than enough to deal with fourth-order demonic beasts. Su Mo said embarrassedly.

Zhang Xingtian had long since stopped taking medicinal materials as a thing, after all, there was an empire behind him, but what he didn't expect was how harsh the refining of the pill would be on cultivation! If his Heavenly Dao cultivation was barely refining this pill, if he reached the limit of the Dan Dao, then what realm would he need for cultivation.

Although there are many medicinal materials, they are all quite common, and two days later, Su Mo entered the state of refining, as he thought before, he failed nearly ten times in a row before he succeeded once.

But controlling more than a hundred medicinal materials at the same time, Su Mo was also in a hurry! Only then did he know that if this was changed to the perception of a quasi-Heavenly Dao cultivator, it would not be possible to succeed once.

After a little rest, refining again, Su Mo's technique was much stronger! A day passed, and the pill had also been successfully refined! At this point, Su Mo stopped refining, because these six were enough to solve the fourth-order demonic beasts of the Demon Beast Mountain Range.

After that, he stepped on the top of the stairs, and Zhang Xingtian didn't know about the Demonic Beast Neidan, so he saw Su Mo leaving, and then came to Su Mo's room.

But when he found that there was no Neidan left from before, he suddenly felt that something was wrong, what did this guy want so many Demonic Beasts Neidan to do? Could it be that he was eating! Thinking about it carefully, it was impossible, the energy in the inner door was not something that the cultivator could bear, and it seemed that he could only wait for him to come back and ask about it.

I'm not sure what the reason is, Zhang Xingtian still collects Neidan according to Su Mo's request! Since Su Mo arrived, the pressure on Chengtian Wall has been much less, and he didn't find anything suspicious about the latter, so he can only think that Su Mo used Neidan elsewhere.

At this moment, Su Mo stepped on the ladder, but he also found the problem, the ladder was full of rich energy, and it was very difficult for Su Mo to take a step in today's Dao cultivation.

Su Mo was a little distressed, under such coercion, if he wanted to climb to the top floor, it was simply a fantasy! He couldn't help but curse secretly, no wonder this old boy was so generous, it turned out that this ladder was used to trap people.

The steps are difficult, and it is very appropriate to describe this moment! Su Mo calmed down and found that these stairs were engraved with strange runes! And the coercion was also very different from the energy wall that the cultivator had beaten.

On the top of the stairs, I couldn't feel any energy fluctuations, but it was invisibly like the essence of the air, hindering every move of the body, and the corridor was very old!

There are no passages on both sides of the corridor, Su Mo is curious, those Heavenly Dao powerhouses and Tianzun should be active on the third floor, but it is obvious that there is nothing here, except for the stairs that are full of brick walls on all sides.

Teleporting! Thinking that they went back and forth between the floors through the method of teleportation, through the gap between the stairs, Su Mo looked at it, it was pitch black, although he was determined to go up and cultivate for half a year, but this kind of coercion was beyond Su Mo's bearing.

Zhang Xingtian was dealing with the matter at hand in a secret room, and a white-haired old man walked from outside the door, sighed and said, "How can you give him the qualification to enter the top floor of the Chengtian Wall? ”

Frowning, Zhang Xingtian said respectfully: "Ancestor, don't worry, he Chen Mo is not a stubborn person, with his current strength, he will return after holding on for a day at most, and nothing should happen." ”

How could the white-haired old man not know that since the appearance of the Heavenly Wall, which one of them has successfully stepped on the top floor! At most, it is only ten stories high, and if this kid has the slightest impulse, he will probably not be able to come back! It is a pity that he will die like this.

At this time, it was almost evening, but Su Mo only walked to the position of the third layer! And the consumption of cultivation in his body was terrifying, and then he could only meditate and cultivate on the spot, and the five elements were running, and Su Mo suddenly found that the five elements in his body could actually absorb the coercion here.

Dannu also seemed to be aware, "This ...... Coercion cannot be formed by a cultivator! It should come from the hands of a certain immortal cultivator, and the Five Elements are not only a necessary condition for advancing to the Heavenly Dao! It is also an indispensable step for an immortal cultivator. ”

"Immortal cultivator?" Su Mo sighed, no wonder he noticed that this coercion was a little strange! But if there really was an immortal cultivator, his human ability would definitely shake the heavens and the earth, but why didn't he come forward to stop the disaster on the continent? Could it be that the immortal had passed away.

Thinking about it, it is unlikely, cultivating to the Heavenly Dao can live for thousands of years! Immortal cultivators will definitely not have such a short lifespan, at this moment, just by cultivating for a moment, the pressure on the ladder has been reduced a lot.

Seeing the situation, Su Mo got up and walked towards the fourth layer, but unexpectedly found that it was a lot easier! Out of curiosity, Su Mo asked, "The five elements can absorb the coercion here, so can it play an evolutionary role?"

Danu said: "Since it is the origin of the Immortal Dao, the absorption of the five elements can naturally evolve! I just don't know how big the effect is." ”

Sanyuan didn't know much about cultivating immortals, but he had only heard about it! Therefore, he did not speak, but he was also a little worried, since the formation of the mainland, there have been people who have tried to cultivate immortals, and it is rumored that some people have succeeded, but the mainland has never seen it! Therefore, no one knows what happened in the end.

Knowing that he could evolve the Five Elements, Su Mo was overjoyed, there were still a hundred years before the Heavenly Tribulation, so the young master would cultivate it for a hundred years! Who would dare to invade the Four Directions Continent when he saw it.

Su Mo thought that the ending in the dream had changed, and the cultivators in the dream thought that he was dead!

In the gloomy corridor, Su Mo did not dissipate his sorrow because of the atmosphere, and at this time he had already reached the height of the seventeenth floor! In the secret room, Zhang Xingtian calculated the time, thinking that Su Mo should have returned, but he was still nowhere to be seen.

Zhang Xingtian was well aware of the danger on the top of the stairs, and if he couldn't bear it and still insisted on not retreating, then he would be destroyed by invisible coercion! Once upon a time, Zhang Xingtian and his senior brother broke into the Chengtian Wall for the first time, and that time they reached the tenth floor! Zhang Xingtian couldn't continue to hold on, so he began to retreat, but his senior brother was torn apart by coercion in front of him.

Zhang Xingtian still remembers that scene vividly, and he didn't have time to think about it for the moment! He got up and walked up the stairs, and the worry in his heart became heavier and heavier! If he was just a Heavenly Dao cultivator, it would be easy to say, but he was still an eight-rank Dan master! If he died like this, it would be a pity.

On the top of the stairs, Zhang Xingtian had already begun to burst into cultivation, and walked up step by step! Until the next morning, Zhang Xingtian stepped into the height of the eleventh floor, but he did not find the slightest trace of Su Mo.

He didn't think that Su Mo could reach such a height, it was already Zhang Xingtian's limit at this moment, so he could only return, but he was also very melancholy, there was no shortage of imperial Dan masters! But the Eight Rank Dan Masters almost didn't exist, and now that one of them finally appeared, he also died, and he regretted it very much in his heart, regretting that he shouldn't have been given the qualification to enter the ladder.

This matter soon spread throughout the empire, and although Li Shiyu didn't like Su Mo very much, he was also a companion who came here together!

However, at this moment, on the top of the stairs, Su Mo had already reached the height of the thirtieth floor, and he meditated for a moment every third floor, firstly to restore his cultivation, and secondly, to evolve the five elements!

There was no shortage of time, so he was not discouraged! On the contrary, he found the joy of cultivation, but this kind of cultivation had no effect on cultivation, so he was a little unwilling.

One of them said angrily: "That demonic beast will give up if you don't listen to the order now, but how to say it is also one of our heritages, it is really hateful to be killed by those cultivators in the Chengtian Wall in the past few days." ”

"When will we be able to return to the mainland and make the self-righteous people of the mainland pay?" said a man who stood up from his seat.

Beside Mu Tiantian sat a huge golden-armored alien, only revealing two eyes to look at everyone! Then he got up and said, "Why don't I want to kill back to the mainland!" But we can't cross that Chengtian Wall, so no amount of hatred can be used. ”

Then he said: "How is the fourth child's calculus going?"

At this time, a strange man in cloth clothes walked in from outside the door, hugged his fists at everyone and said: "Little brother is not talented, only today has calculated the lifespan of the sky-bearing wall! According to the hexagram, the city wall will collapse in fifty years!"

Fifty years! Everyone was silent, and the golden-armored stranger nodded, "Fifty years is nothing to us, you should prepare early when you go back! ”

Because of his words, the Inhuman tribe began to prepare for the invasion in fifty years! Fifty years of preparation time is not a tense time, but it is not a long time, for cultivators, there is not much that can be done in fifty years! If you are unlucky, you can cultivate a realm, and cultivating a few disciples is nothing more.
