With the passage of time, Zhen Shuai only felt indescribably comfortable all over his body, those originally violent energies poured out from the underground of the secret room like a whirlpool, and were swallowed by the Dark Dragon Devouring Flame like a moth to a fire, refining and inhaling into the body, the entire secret room gradually calmed down, but the energy like a tide was like a flood that burst the embankment, no matter how much Zhen Shuai absorbed, there was always more energy filling the secret room and the not small space for Zhen Shuai to absorb.

Zhen Shuai was a little surprised, and immediately used the eyes of the stars to transmit it downward, which was not trivial, and he was almost shocked into a cold sweat.

Under the secret room is a huge completely crystallized pulsating heart, the powerful existence of the heart is extremely huge, as the core of energy, naturally as solid as a rock, the energy is amazing, and the crystallized heart is naturally the core of the existence of the peak realm, the energy contained in it is not only the energy of the heart itself, it must also have the ability to control all the energy in the field between breaths.

And Zhen Shuai could recognize that it was the heart of the dragon clan, because the heart of the phantom dragon was almost a replica compared to it, but in terms of volume, the heart below was at least ten times that of the heart of the phantom dragon.

In fact, the phantom dragon is just a cub of a dragon-type phantom beast, which is equivalent to the age of about 1 year old for humans, but it has the strength of the peak of the merger realm, and it does not breathe dragon just because the phantom dragon has not reached that age, not that the phantom dragon belongs to the pseudo-dragon or sub-dragon species.

If the phantom dragon fully grows, not to mention Zhen Shuai and the others, ten current Zhen Shuai may not be enough. Coincidentally, the Phantom Dragon's parents were wiped by the berserk energy in the battle between Zhen Shuai and the Angel, and were seriously injured in an instant, and then were discovered by other Phantom Beasts and devoured the dragon's body, never coming back.

And this heart is the ancestral dragon heart of the Phantom Dragon family, and each generation of Phantom Dragon relies on this dragon heart to absorb energy for cultivation, so as to gain strength beyond other races of the same age. The dragon heart, which originally provided a source of cultivation for the dragon, was changed to supply Zhen Shuai for cultivation, which was somewhat similar to a nuclear power plant dedicated to the daily life of a small town, which was completely supersaturated and wasted to the extreme.

Seeing this, Zhen Shuai also felt that he might not be able to absorb so much amazing energy, although he would not explode and die, but maybe the excess energy would cause irreversible damage to the heart of the fairy or the veins at the critical moment of advancement, and this kind of thing was not unexperienced.

Zhen Shuai immediately moved, and sent a part of the energy that poured into the room to Chen Xuansheng's side, because the building materials of the secret room were too special, even the eyes of the stars could not see through the past to see Chen Xuansheng's situation, and could only slightly sense that the indoor energy was extremely stable.

Zhen Shuai only dared to gradually increase the amount, and only after confirming that there was no change on Chen Xuansheng's side did he take half of the dragon heart energy for his own use, and half for Chen Xuansheng's advancement.

If so, I don't know how long it took, Zhen Shuai felt that his body had been completely transformed, and all the energy in his body had been spit out from the heart of the fairy yuan to the storage at the cellular level, and the heart of the fairy yuan could be called unbearable hunger and thirst.

Zhen Shuai immediately let out a soft roar, and a sound like bursting beans sounded all over his body, just changing a law decision, all of which produced the sound of wind and thunder due to the huge power of his fingers.

The heart of the fairy fate frantically absorbs the external energy at a speed that is more than 10 times higher than the original transmission efficiency, and this cycle is directly at the cellular level, not only in the original operation of the blood meridians, in this way, Zhen Shuai's ability to store and mobilize energy is extremely amazing, and the original limits seem to have been completely broken.

"Is this considered an advancement?" Such a calm advancement is something Zhen Shuai has never experienced, and he had to break through some obstacles before, but now it is completely natural.

After confirming that he had advanced to the merge realm, Zhen Shuai originally planned to stop and get out of the level, but found that after sensing that Zhen Shuai was more powerful, Long Xin suddenly accelerated the absorption and gushing out of energy, and the entire secret room was forcibly infused with more dense energy.

At this time, Zhen Shuai was a little confused, whether to continue to cultivate or simply go out of the customs to adapt to the new realm and then try to forge ahead. After a while of the ideological struggle, Zhen Shuai happily accepted the choice to continue cultivating.

After all, there was no such a stable and energy-rich cultivation opportunity before, and it is estimated that there will not be too many in the future, so it is better to seize the opportunity and suck up a full suck at a time, in case of advanced Mahayana, even if you don't advance Mahayana, after getting an upgrade, it will be the peak of the merger, and you can kill Beiyi's arrogance in seconds, hit Ryan's arrogance, and tease Xiao Lian's indifference.

The most important thing is that only with strength can you protect Xuansheng and protect the lost past, and only then can you have the possibility of struggling in the unstoppable fate of the reincarnation of the Heavenly Dao.

The calm Zhen Shuai began to start a new cultivation process. With the assistance of the ability of the Eye of the Stars, the energy distribution in the room is almost accurate to the millimeter level, as clear as watching a high-definition TV at close range, and its semi-crystallized flesh and the preliminarily crystallized Immortal Heart have made the energy absorption and refining ability reach a new level, of course, the upper limit of the energy stored in the Immortal Heart is also extremely amazing.

The mana that Zhen Shuai stored and absorbed during the advance was exhausted in the process of comprehensive transformation, and now he re-refined the mana only to find that his immortal heart was already as vast as a sea of smoke, and he originally needed to divide half of the dragon heart energy even if he took it back, but considering that Chen Xuanshang had adapted to the improvement of abundant energy, if he suddenly drew salary from the bottom of the kettle, it would inevitably interfere with Chen Xuansheng's cultivation, so Zhen Shuai continued to maintain half of the dragon heart energy, and swallowed the other dragon heart energy in one gulp.

After an unknown amount of time, the heart of the immortal fate overflowed again, and the energy in the body was rapidly compressed and purified by the life-saving exercises, and began to move from semi-crystallization to crystallization......

When Zhen Shuai finally walked out of the secret room, the whole person seemed to be fluttering and didn't feel his weight at all, and with a little force, he came to everyone like an instantaneous movement.

Everyone was stunned.

"Is there anything on my face?" Zhen Shuai casually opened a space door and looked at himself through the reflection of the void before saying, "He's fucking handsome again." ”

"You ..... you ....." Ryan, you didn't say a second word for a long time.

"Yo, advanced Mahayana?" Bei Yi said with a smile on his face.

"It's a fluke, it's a fluke. Zhen Shuai was a little embarrassed and stroked the snow and laughed.

"That's right, we're working hard outside, you're enjoying yourself in the secret room, if we hadn't advanced two levels in a row, we'd be by you!" Bei Yi said in an obviously ostentatious tone.

"You have also advanced to Mahayana?" Zhen Shuai said with a surprised smile.

"Yes, are you surprised, are you not surprised?" Xiao Lian wiped the blood stains on his hands and said with a smile: "Thanks to those demons and angels who suddenly went crazy and started a large-scale fight, we really touched a few big fish under the troubled waters, and finally it was a fluke to advance, hahahaha, it was pure luck." ”

"No, it's only been a long time, which of the big names in the Heavenly Realm have you killed to make you advanced?" Zhen Shuai couldn't feel the passage of time at all during his cultivation.

"How long? I'm afraid we've been here for less than ten years!" Ryan said in surprise, and Zhen Shuai's hand that was shocked to get the teacup froze.

"Ten years? It's been so long, haven't we only been here for a few days!" Zhen Shuai hurriedly drank all the water in the teacup, and a cool fragrance made his short-circuited head sober up a little.

"Cultivation is endless, time flies, and ten years from the peak of refining the void to the Mahayana is not long at all. Xiao Lian said with a distraught expression.
