Half an hour later, Chu Yu said while burping:

"Master Su, Hiccup, protect the Dharma for me, Hiccup, I've got to settle down, Hiccup. ”

"It's a small thing. ”

In fact, there is no need for the Demon Immortal Jade to protect the Dharma at all, because after eating this Fire Walking Dragon Treasure, Chu Yu actually activated a layer of Fire Xing's energy shield on his own the moment he entered his meditation, which is estimated to be caused by the fire spirit aura in his body being too strong and the spiritual power being revealed.

"Lord Suhu, I really hope that this son can also be like you back then, dominating the Six Realms and being invincible. ”

After looking at Chu Yu and calming down, the machine spirit muttered in his mouth, and a few tears seemed to well-up from his big eyes.

After eating this fire-colored lotus, Chu Yu's dantian seemed to be about to explode, and it was already several laps larger than the normal dantian, Chu Yu hurriedly accelerated the smelting method in his "Heavenly Fire Dao" mental method.

With the difficult start of the smelting method, the dragon treasures that were eaten by Chu Yu were also gradually melted away bit by bit at the dantian, and then turned into the power of the mental method and poured into Chu Yu's inner pill, while washing Chu Yu's inner pill while wandering in Chu Yu's various meridians, as the operation of the smelting method gradually accelerated, the fire dragon treasure accumulated in Chu Yu's body was also almost half digested by him.

Finally, Chu Yu only felt that there was a crackling sound in his body, and then nine small meridians appeared in Chu Yu's body, which also meant that the "Heavenly Fire Avenue" mental method was officially promoted to the heaven-level lower grade, obediently, the heaven-level lower-grade mental method, Chu Yu couldn't think of it before, if it weren't for this high-grade dragon treasure of the fire line, Chu Yu really couldn't tell which life he would be able to have such a powerful spiritual material to help him advance to the heaven-level lower grade.

"Damn, it's finally over, I'm exhausted!"

The Demon Immortal Jade Pei was also tired and sweating profusely outside Chu Yu's body, and even his figure seemed to be a few laps smaller, it seemed that Chu Yu was able to advance the "Heavenly Fire Avenue" to the heaven-level lower grade so smoothly, the Demon Immortal Jade Pei should have helped him a lot, but it was also right, Chu Yu was just a little guy in the early stage of Nirvana, how could he control such a high-grade dragon treasure, and it was strange not to burn him!

"Calm down, refine the remaining dragon treasures, and then use the surrounding fire aura to help you advance to the later stage of Nirvana!"

I saw that after the machine spirit finished speaking to Chu Yu, he took a deep breath again, and held his breath again to concentrate, as if he was helping Chu Yu to protect the Dharma or assist in breaking through.

Chu Yu naturally listened to the words of the machine spirit, suppressed his excitement, and once again started the smelting method, the "Heavenly Fire Avenue" mental method that had been promoted to the lower grade of the heaven level was really extraordinary, and even this smelting method was much faster, just now it took a full night to refine the half of the dragon treasure Chu Yu, but the remaining half, Chu Yu only took two hours.

"Okay, the last step, borrow the aura of heaven and earth, break through!"

This time, Chu Yu's breakthrough to the middle stage of Nirvana seemed to be a matter of course, without any obstacles, and he was smoothly promoted to the middle stage of Nirvana, but Chu Yu's feeling was that except for the large amount of spiritual power in the dantian, the others seemed to be the same as in the early stage, and he was a little disappointed, but he was happy as soon as he felt the additional fifty-four small meridians brought by his heaven-level lower grade heart method.

There are fifty-four more small meridians to circulate Zhou Tian for him, and the absorption speed of this aura is the same as that of the immortal cultivator himself

The meridians are directly proportional, the more meridians, the faster you absorb the more, and it grows exponentially, rather than simply one plus one equals two.

"Huh, what's this?"

Chu Yu found that there was actually a small pill in his dantian, which frightened Chu Yu, and quickly attached his consciousness to it and began to investigate, this investigation did not matter, Chu Yu's mind suddenly had some more information about the mental method of "Heavenly Fire Dao".

It turns out that the pill that suddenly came out of the Chu Yu Dantian is called the Heavenly Fire Inner Dan, as the name suggests, it is the Inner Pill condensed by the mental method of the "Heavenly Fire Avenue", as for its function, it can be regarded as the second Inner Pill of the Immortal Cultivator!

The benefits of this second inner dan don't need to be introduced too much, in the battle of the same level between one inner dan and two inner dan at the same level, it is naturally self-evident who wins and who loses, and the appearance of this second inner dan means that Chu Yu is very likely to cultivate the second yuan infant in the future, and then the second doppelganger, this is the opportunity that many immortal cultivators dream of, Rao is demon fairy jade pendant did not expect that Chu Yu could cultivate the second inner dan in the Nirvana realm, Chu Yu is really blessed.

There is a reason why Chu Yu is lucky, because the formation of this Heavenly Fire Inner Pill is extremely difficult, first of all, the first requirement is that the "Heavenly Fire Dao" mental method must be advanced to the heavenly level, which stumps how many heavenly pride, after all, breaking through to the heavenly level is not just a matter of casually relying on the accumulation of fire spirit materials to succeed, it must be a big opportunity like Chu Yu.

The second is that the realm of the immortal cultivator itself must be the Nirvana realm, because when the Dan realm was built, the inner pill had just been formed, and it was not stable, and it was very easy to cause damage to one's own inner pill if he cultivated the second inner pill, and the infant realm was completely impossible to cultivate the second inner pill, so he could only choose to practice the second yuan infant which was dozens of times more difficult than the second inner pill, so Chu Yu's trip to the crypt this time was definitely a big profit!

"Ah, I see, this "Tianhuo Dao" mental method is really powerful, the second Inner Dan, a good thing, hehe, Master Su, I have a second Inner Dan, don't you praise me?"

Master Su was already tired at this time and fell asleep again, after all, he helped Chu Yu absorb a whole high-grade dragon treasure, and the duration was extremely long, Lord Su was originally a spirit body, and all that was consumed in this process was his mental power, and he finally survived until Chu Yu's mental method and realm were both successfully promoted, and finally he couldn't help but fall asleep.

"Lord Su? Is this falling asleep again? It seems that Lord Su must have helped me a lot, just like the last time I was in Jinglong Pond, alas, I really don't know how to thank him." ”

Chu Yu naturally knew how much this Demon Immortal Jade Pendant's Instrument Spirit had done for him, but if it was as a thank you, he seemed to have no choice but to work hard to improve his strength, but yes, his strength was strong, and Lord Su should be able to save a lot of worry.

"It's time to go out, hehe, they're afraid they're not waiting outside. ”

Only then did Chu Yu think of Dong Yi, who had been guarding outside, and his disappearance was a day and a night, hoping that everything would be fine outside.

However, just as Chu Yu was about to leave, he suddenly found that there was an inexplicable energy dragon in the position of the fire-colored lotus, this energy was not the fire aura, nor any other kind of aura, but the coercion of this energy dragon was very powerful, but it didn't seem to have woken up yet, and if it didn't take the initiative to feel it, it wouldn't be affected.

"Is this dragon energy?"

This is the only thing Chu Yu can think of, and then Chu Yu took off the jade card on his chest, before Master Su said, this jade card used to be a dragon treasure, but it was because it lost its original function because of its dragon energy, if the thing in front of him was the so-called dragon qi, maybe it could help him repair it.

Not to mention, the moment Chu Yu touched the dragon qi with the jade card, this energy dragon went directly into the jade card, hey, Chu Yu really guessed correctly, and carefully took the jade card on his chest again, although this jade brand dragon treasure got the dragon qi, but Chu Yu didn't know how to activate this thing, so he simply let it go first, and then asked after Master Su woke up.

His top priority now is to get back to the ground quickly, don't let Luo Ling and them wait, as for how to go back to the other side, Chu Yu is very good this time, the most direct effect of the promotion of "Heavenly Fire Avenue" to him is the improvement of the spiritual power of fire in his body, especially the spiritual fire in his Heavenly Fire Inner Dan, the level is already beyond the ordinary earth fire such as magma, Chu Yu is not impossible to swim in the magma now, but the premise is that there are no women around.

"You said that Chu Yu didn't die inside, right? ”

"Dong Yi, you big fool, if you crow's mouth, I'll throw you down too. ”

At this time, the four Luo Ling were outside the cave discussing how to enter it to search for and rescue Chu Yu, but the next moment, Chu Yu rushed out of the cave mouth alive.

"Yo, people are really together, what are you doing here?"

"It's nothing, just waiting for a second fool. ”

"Well, Miss Yun'er, you're a bit too much. ”

"Yun'er, your name?" Cao Mufeng mended.

"Haha, Xiao Yuzi, you finally came out, we almost went in to catch you. Dong Yi mended the knife.

"Big fool, you talk the most, I'm not falling into the pit!"

"Hmph, I'm having fun by myself, and I'm reluctant to come out. ”

Luo Ling said quietly.

"Haha, you don't know, I got a big chance in it this time, hahaha, really, the rest of the battle will be left to me, you can rest. ”

Chu Yu was stunned here, and Zhao Yun'er continued to mend the knife.

"See, isn't it just the middle stage, it's really amazing, I'll take a look, yo! Why is your realm still the lowest?"

"Well, okay, I'll put up with it, count you ruthless. ”

Among the few people, although Luo Ling is also in the middle stage of Nirvana, her aura is not very stable, which is a sign that she is about to break through to the late stage, so Zhao Yun'er is right to say this, and Chu Yu can only admit it.

"Okay, okay, Chu Yu, do you still need to rest, if you don't need to, let's hurry up, it's been delayed for several days. ”

"I'm fine, let's go. ”

Then Chu Yu and the others began to walk towards the depths of this Qinglongmen ruins, after all, it was the dragon treasure that was born, or the probability of the central area was greater, and it was only then that Chu Yu realized that he was afraid that the dragon treasure he ate was the one that was about to be born.

But Chu Yu won't say it, and he is not stupid, in case an old monster knows about it and then refines him into a human pill, it is terrible to think about.

"Where do you think the two teams are now?

"I don't know, I guess it's not more unlucky than us. ”

"That's right. ”
