Sitting cross-legged on the ground, Yi Chen stared into his body, and on that foundation, a corner was gradually consolidating, and a dark yellow illusory flame was faintly rising from it.

This is the true fire of the foundation, it is the exclusive means of the monks in the foundation building period, and contains the way of the combination, I don't know how many times more powerful than the fire condensation technique, but it can only be used after the middle stage of the foundation, and it is precisely because this fire is still illusory.

After a moment, Yi Chen withdrew his gaze from the illusory true fire, and now what he had to do was to officially step into the foundation.

The nine aura vortex above the dantian is gone, all of them are injected into the Dao Foundation, turning into that corner of condensation, Yi Chen is now in the Dao, no longer a Qi Condensing Monk, but standing on the edge of the foundation, as long as that corner of the Dao Foundation is completely solidified and stable, you can step into the foundation building period.

The surrounding thunder sea roared, and the sky trembled, but it failed to disturb Yi Chen, his mind focused on the Dao Ji, and after a while, his eyes lit up, and at the same time, the magic trick in his hand moved, and began to gather all the spiritual energy in his body on that corner, intending to make it quickly condense down.

This is not easy, it requires a huge supply of spiritual energy, but since the Daohua Pill was suppressed by the ancient array, the endless spiritual energy in his body has disappeared, and the Gathering Spirit Array has been shattered by the Daohua Pill, so after emptying the spiritual energy in his body, Yi Chen had no choice but to stop, and the corner of the Dao base has not yet been half condensed.

After opening his eyes and frowning slightly, after a deep groan, Yi Chen pursed his lips, patted the storage bag, and took out all the spirit stones, but there were not many, only a few high-grade spirit stones, or the leftover after entering the prison realm, the top-grade spirit stones had already been consumed, and the middle-grade spirit stones were also spent by the magic weapons he had collected in the sect before, thinking of this, Yi Chen couldn't help but want to vomit blood, those magic weapons were not of much use to him when he used them to deal with Jiao Beasts......

"It's better than nothing...... "Shaking his head and sighing, Yi Chen held these several high-grade spirit stones in the palm of his hand and began to replenish the spiritual energy, now that the thunder sea is turbulent, the space is not stable, and he can't set up the spirit gathering array, just rely on these high-grade spirit stones and his own recovery, this foundation may take some time.

After a while, Yi Chen's face moved slightly, and most of his aura recovered, in the palm of his hand, several high-grade spirit stones were shattered and scattered into ashes, he pursed his lips, and immediately wanted to continue to urge the aura to infuse the Dao Ji, but at this time, he frowned slightly, and when he raised his head slightly, he saw that the heaven-covering demon shadow was still struggling and escaping in the thunder sea, and was not killed.

"This demon is really difficult to kill...... A chill flashed in Yi Chen's eyes, even this kind of world-destroying heavenly tribulation couldn't kill him, obviously he underestimated the trickiness of this demon a little.

"After I have built the foundation, I will cause the thunder to destroy it. After pondering for a while, Yi Chen nodded, he had already made up his mind in his heart, as he got closer and closer to the foundation building period, the power of this thunder tribulation became more and more powerful, and it should not be difficult to destroy this demon at that time!

Taking a deep breath, Yi Chen pondered again, and activated the aura in his body and poured it on the Dao Ji, and at the same time he began to think about the escape method after the thunder tribulation stopped.

"At this moment, due to the fury of the thunder sea, the trend of space collapse has temporarily stopped, but once the thunder tribulation is over, I am afraid that the space will collapse immediately, and because of this tribulation, it will be even faster, if you only fly in the sky, I am afraid that it will be too late to escape from the center of the prison realm......" Yi Chen's heart sank slightly, the demon clan had not been destroyed before, and he stayed with the heart of death, but at this moment, the demon clan has almost been eliminated, and he has embarked on this new path, which is about to build a foundation, so that he began to value his life.

If they can live well, who wants to die?

"If I start to escape from the center of the prison at this moment, I should still have time to avoid the collapse of the space, but...... This demon has not been eliminated, I can't rest assured......" Many thoughts passed through his heart, Yi Chen secretly said, this heaven-covering demon shadow has always been a thorn in his heart, and he can't see this demon destroyed under the heavenly tribulation with his own eyes, he has never been able to rest assured.

Under the infusion of the huge aura, after a while, the corner of the Dao Ji was condensed by nearly a quarter, but it was still a little close, Yi Chen opened his eyes, and there was helplessness in his eyes, but then, his expression suddenly sharpened, and he immediately stood up, summoned the flying shuttle, and stepped on it and went straight to the Heaven-Covering Demon Shadow!

"Kill this demon first!"

Yi Chen's face was indifferent, and the electric light traveled all the way, causing the power of the Heavenly Tribulation to be even greater, at this moment he was close to building the foundation, and the thunder light that led it all had the power of sinking and destroying the world, and after bypassing him, it crashed down on the ground, leaving a huge scorched black pit!

Not far away, the Demon Shadow of the Sky Covering the Sky fled in embarrassment, this thunderstorm caused it to be extremely harmful, so that most of the monstrous demonic qi on its body was dispersed, the skin and flesh were opened, and a pair of pitch-black wings were bombarded to tatters, and one wing was broken, and only half of it was left!

Suddenly, its expression changed, and it felt that a terrifying qi machine appeared nearby, and the light in its blood-red eyes instantly contracted, and at the same time, when it looked back, it couldn't help but be extremely angry, Yi Chen actually drove thousands of tribulation thunder directly behind it!

"Damn the Terrans!, how could he not be afraid of the power of this Heavenly Tribulation!" The Heavenly Demon Shadow couldn't help but be furious, this Tribulation was descended with Yi Chen as the center, but it could clearly see that those Tribulation Thunders had all bypassed when they were about to come into contact with the latter!

But soon, the Shadow of the Sky Covering understood that as Yi Chen got closer to it, the terrifying qi it felt became more and more huge, as if it had a supreme coercion that could override this world, which made it tremble in its heart, and chills ran chills behind it, it must be the existence of this qi machine, which made the Heavenly Dao afraid and retreated!

The killing intent of the Heaven Covering Demon Shadow instantly became extremely strong, Yi Chen had such a power when he built the foundation, if he was allowed to continue to grow, he would definitely be the next Zhang Fan in the future, and he would become the enemy of his demon clan!

"Death to this seat!" "Resist the thunder, the shadow of the demon shadow suddenly turned around and slapped it with a palm, this is its angry blow, as if overwhelming the heaven and earth, vowing to kill Yi Chen, the power is almost unstoppable, Yi Chen does not have Zhang Fan's big array to help at this time, just a weak ant monk, it is easy to kill him!

But at this moment, Yi Chen sneered, did not dodge or dodge, and even controlled the shuttle to approach quickly, bringing thousands of world-destroying thunderbolts, this demon was too arrogant, vainly trying to resist the thunder and kill him, but obviously underestimated the horror of the power of the thunder sea centered on him!

"Ah!!" The clutch of the Heaven-Covering Demon was approaching in an instant, but then, it was blocked by the dense thunder sea, and the skin and flesh that were immediately bombarded opened, and the black smoke rose wildly, and at the moment he couldn't help but roar out in pain, and withdrew his palm like lightning, and Yi Chen took advantage of the power of the thunder sea to hit it hard!

"No, I must leave the prison realm first, if I am dragged down by this kid again, I will be annihilated under the Thunder Tribulation!" The blow failed, and the Heaven-Covering Demon Shadow suddenly became furious, but at this moment, its blood-red demon light flickered, and it glanced at the ruined Dao place, and its eyes lit up, with Yi Chen's departure, the power of the Thunder Tribulation there gradually weakened, and the space was empty again, about to collapse, it was a good opportunity to tear the space away!

"If you just tear out the spatial crack that allows me to pass through, you should be able to do it!" The blood-red eyes couldn't help flickering, the demon army was still there before, and it was extremely difficult to tear out the spatial crack that allowed the entire demon army to pass through, but at this moment, all the subordinates have been wiped out, and there is only one left, just tear the hundred-zhang passage, and its ability should be enough!

At that moment, the blood-red eyes flashed, and the figure suddenly moved, as fast as lightning, and even the speed of the thunder seemed to be faintly unable to catch up, and it disappeared in front of Yi Chen in an instant, heading straight for the ruins of the dojo!

Yi Chen's complexion changed, and he immediately turned around, seeing the shadow of the sky-covering demon that was frantically sweeping towards the ruins of the dojo, a chill crossed his eyes, this demon rushed there desperately, he must want to escape, he must not let it get his wish!

"Don't think!" A cold deep cry spread, Yi Chen immediately turned around, and drove the shuttle into a streamer to chase away, but the demon was too fast, and it was already close to the ruins of the dojo in the blink of an eye, and raised his terrifying arms, pulling up in the void in front of him, to forcibly cut a passage!

The pitch black crossed, the space was torn apart, and a deep passage appeared, but it was less than a hundred feet, and it healed quickly, and the expression of the Heaven Covering Demon Shadow changed, it was hit by the thunderstorm and had some injuries, and its strength weakened a lot at this moment!

"Want to escape?!" Just as the Heaven Covering Demon Shadow wanted to continue to tear through the space, Yi Chen's eyes narrowed slightly, a dangerous light crossed his eyes, and he arrived indifferently, and at the same time, when he was a hundred feet away from the demon, he suddenly stopped, sat down on the ground, and formed a cultivation seal, wanting to build a foundation in one fell swoop and lead to a stronger thunder tribulation!

His mind quickly condensed, Yi Chen looked at the Dao Foundation in his body, that corner was almost condensed, and he was about to succeed, just about to step into the foundation, at the moment he looked solemn, and all the remaining spiritual energy in his body was urged, and he poured straight into the dantian!

"Condensation!" suddenly sighed in his heart, and the few spiritual energy poured into the corner of the Dao base, at this moment, this corner immediately condensed, and at the same time, in Yi Chen's body, there was a burst of Dao Ming, and an extremely comfortable feeling spread out between his body, and a line of inscriptions on the Dao base, flashed with brilliant brilliance, and there was a majestic Dao intent gushing out, and the empowerment generally fell on this corner, making it instantly stable!

Build the foundation!

The clouds in the sky rolled up suddenly, revealing a terrifying extinction qi machine, the entire prison realm trembled, Yi Chen's heart was shocked, in front of his eyes, there was a roar in his mind, and an extremely vast ocean of sea appeared and formed, in which the divine consciousness was surging, and suddenly set off a monstrous wave in Yi Chen's heart!

The sea of consciousness has been formed, and with the divine sense, he has truly become a foundation building period monk!

But at this moment, Yi Chen was suddenly stunned, he looked at the sky above the sea of knowledge, and then froze, at the top of the huge waves, at the end of the misty depths, he seemed to vaguely see a magnificent immortal palace looming, which was a scene that ordinary monks had never seen to build a foundation!

"Immortal ......" couldn't help but murmur in his mouth, Yi Chen's eyes showed an unprecedented excited light, this light was a little trembling, but firm, a trace of qi faintly coming out of the fairy palace was sensed by him, as if above everything, it has never been seen in this world!

"This way, you can pass through the immortal ......" Yi Chen couldn't help but tremble, he violated the heavenly principles and built the foundation with his body outside the Dao, and embarked on a road against the sky without returning, but at this moment, at the end of this Dao, he sensed the breath that did not exist in the world, this qi, Ling Tian Jedi, must belong to the legendary 'immortal'!

This is a fairy road!
