Until this day, the ground fire in the alchemy room was finally turned off, and Yu Yilie also walked out with a calm expression, but in the depths of his eyes, there was a strong excitement.

At this time, in his storage bag, there were two jade bottles, a total of twenty Tsukidan!

Now, no matter how bad his qualifications are, he can successfully build a foundation, and even be able to successfully break through the Purple Mansion Realm, double cultivation of the Dharma Body, and break through in one fell swoop!

After bidding farewell to Deacon Ma in the main hall, Yu Yilie went to the Xuanlei Sacrifice Star Tower to apply for a secret room.

This is not only the most powerful attack formation in the Hundred Refining City, but also the strongest defensive formation, and it is also an excellent retreat place for monks to break through the foundation building period.

At this time, in a secret room on the third floor of the Xuanlei Sacrifice Star Tower, Yu Yilie decisively closed the stone door and opened the prohibition here.

In this way, unless the Hundred Refining City was breached, no one would be able to disturb him.

Even the monks of the True Dan Realm couldn't open his stone room.

Sitting cross-legged on the stone bed, there is a spirit gathering array here, which can gather endless spiritual energy here.

Closing his eyes and concentrating, Yu Yilie quickly operated the true technique of melting fire and quenching, absorbing the surrounding aura into his body, refining it into mana or true qi, supplementing the mana and true qi that were not yet full in the dantian and sandalwood.

Time passed little by little, but after his mana and true qi reached saturation, Yu Yilie took out a purple condensation fruit and swallowed it in three or two clicks.

The function of this purple condensate fruit is to purify mana and true qi again, and at the same time improve the body, eliminate impurities, and make the monk have a higher chance of breaking through.

Originally, his huge mana and true qi were decreasing at a speed visible to the naked eye under the energy of the purple condensation fruit, but they were even more condensed, as if a plate of loose sand had been condensed into a rope.

Two days later, the medicinal power of the Purple Condensate Fruit was finally fully exerted, and the mana and true qi in his dantian had also decreased by more than half, but it was more refined and condensed.

Subsequently, Yu Yilie took the Fire Spirit Pill one after another, quickly refining it, and replenishing it to the condensed mana and true qi.

Three days later, his mana and true qi were full again, so he decisively took a Zhuji Dan and began to break through the foundation building period!

The huge medicinal power of Zhuji Dan exploded in his body, and Yu Yilie hurriedly concentrated on the Melting Fire True Technique and the Quenching Technique while absorbing the huge medicinal power in it.

Rao was like this, and the huge medicinal power contained in Tsukidan still held him to the point of pain, and a huge amount of vitality rampaged unscrupulously in his body.

At the same time, his mana was also beginning to grow wildly, and his true qi was surging wildly in his body.

Time passed little by little, Yu Yilie's whole person was red by the medicinal power, and dense beads of sweat appeared all over his body, if you take a closer look, you will find that these beads of sweat contain a lot of gray-black impurities, but it is Zhuji Dan who is cutting the marrow for him and improving his physique.

Fortunately, although the medicinal power of Zhuji Dan was huge, it was quickly absorbed under the simultaneous refining of the Melting Fire True Technique and the Quenching Technique.

At the same time, the mana in his dantian faintly became viscous, as if it was about to turn into a liquid at any time.

And his true qi also condensed into a thick crimson viscous mist, as if it was about to turn into magma, containing explosive power.

At this time, this Tsukidan was digested by Yu Yilie.

His eyes slowly opened, and Yu Yilie's eyes were full of incomprehension, and he wondered, could it be that the medicinal effect of the Zhuji Pill he refined was not enough?

Impossible! He compared the Zhuji Pill he refined with the one given to him by Master Yuan, although it was slightly inferior, but the medicinal power was almost the same, it couldn't be fake!

"Or, because of my dual cultivation of the Dharma Body, the medicinal power of Zhuji Dan was quickly refined by me, and the energy contained in it was simply not enough for me to break through the two at the same time. Yes, others need to prepare many means to break through the foundation building period, but I want to break through at the same time, and the energy that needs to be consumed is naturally much more, and it is not even a matter of one plus one equals two. Yu Yilie muttered to himself, then turned over his hand and took out two Tsukidan from the storage bag and threw them into his mouth at the same time.

Immediately, he fell into the process of refining the medicinal power of the Zhuji Dan again, and the energy of the two Zhuji Dan exploded in his body at the same time, and Yu Yilie hurriedly guarded his mind to urge the True Technique of Melting Fire and the Quenching Technique to absorb the huge medicinal power in it.

At the same time, the mana and true qi in his body were rapidly condensing, gradually transforming into a liquid state.

First of all, the mana began to liquefy first, within his dantian, a huge spiritual energy vortex was converging, constantly rotating, absorbing the medicinal power from the Zhuji Dan, and at the same time, as more and more energy was absorbed into the vortex, the vortex condensed by the mana began to continue to compress and condense, and began to show signs of liquefaction.

A little mist slowly appeared in the whirlpool, as long as it was not long before, I believe that it would be able to condense the mana from gas into liquid, and transform it into a more advanced true element!

At the same time, within his sandalwood, there was also a crimson vortex that was rapidly condensing and forming, but it was slower than the mana vortex.

Seeing that both of them were about to liquefy, unfortunately, the medicinal power of the two Tsukidans was exhausted again, and then Yu Yilie swallowed the Tsukidan into his stomach one by one, constantly refining.

After taking the sixth Zhuji Dan, Yu Yilie finally succeeded in breaking through the foundation building period, and his mana was transformed into true yuan, and since then, his longevity has increased greatly, and he can live to be two hundred years old, and his spiritual sense is transformed into divine consciousness, and he can explore a radius of about one mile.

And after taking the sixteenth Zhuji Dan, Yu Yilie finally liquefied all the Molten Fire True Qi and turned it into a Fire Attribute True Yuan, but at this time, he had not yet broken through the Purple Mansion Realm!

The surging True Yuan kept impacting the limbs and hundreds of remains, as if he wanted to find an outlet, Yu Yilie understood that his opportunity to break through the Purple Mansion Realm had arrived!

Quickly condensing the power of the Seven Spirits in his body and merging it into the True Yuan, Yu Yilie's divine sense led the huge True Yuan to rush towards the Mud Pill Palace where the fire jade was hiding.

"Boom~" resounded in his body like a huge wave crashing.

Zhen Yuan kept banging on the gate of the Mud Pill Palace, but it seemed that it had become extremely strong because of the fire jade, so that he could not make any achievements in repeated attacks.

But Yu Yilie was willing to give up, gritted his teeth and endured the boundless pain, but he refused to give up and urged the huge True Yuan to crash towards the Mud Pill Palace one after another.

Time passed little by little, the true yuan was constantly consumed, and the power became smaller and smaller, Yu Yilie was suddenly annoyed in his heart, swallowed all the remaining Tsukidan, and urged the true yuan to crash towards the Mud Pill Palace again.

Sure enough, with the support of the huge medicinal power, the barriers of the Mud Pill Palace finally began to loosen!

"Boom!" a loud and silent sound sounded in his head.

The surging True Yuan suddenly rushed into the Mud Pill Palace, spreading frantically around, and at the same time, the power of his Seven Spirits and the Power of the Three Souls also condensed into one under the convergence of the True Yuan, forming a translucent figure!

At the same time, Zhen Yuan obviously felt that it was too crowded in the small Mud Pill Palace, so he frantically expanded the space here, and after a while, it expanded to a radius of ten zhang, which was far dozens of times larger than the previous fist!

At this point, the Purple Mansion has become a realm!
