Looking at the embryonic pill calmly, Yao Xin nodded slightly, and once again put the Gathering Spirit Grass and the water-attribute second-level demon core into it, calcining it into liquid, removing impurities, and fusing with each other, these several tedious and delicate steps, he almost did it in one go, without the slightest stagnation.

Seeing Yao Xin's neat action, even Lu Tianyu, a layman who didn't know how to refine medicine, couldn't help but praise it lightly in his heart.

After using the Spirit Gathering Grass to neutralize the furious energy in the demon core, a light blue pure energy was slowly poured into the prototype of the elixir.

When the last drop of blue energy entered the inside of the elixir, the prototype of the elixir with some pitholes on the surface was suddenly repaired to a round and smooth surface, and a faint blue luster appeared on the surface of the elixir, rendering it beautifully.

After completing these steps, the medicine heart did not stop immediately, but after warming the pill in the flame for nearly ten minutes, the white flame in the palm of the palm slowly extinguished.

When the flames disappeared, Yao Xin's left hand sucked a jade bottle on the table, and then put the slightly turquoise pill with a touch of pale blue into it.

"Whew"

With a long sigh of relief, Yao Xin casually threw the jade bottle to Lu Tianyu, and said lightly: "Take a look!"

Cautiously taking the jade bottle, Lu Tianyu put it under his nose a little excitedly and sniffed it lightly, and a familiar fragrance emanated from it, which lifted his spirits.

Looking at the alternating blue and green pills in the bottle, Lu Tianyu relied on his excellent soul perception, and he could vaguely know that this Qi Gathering Pill, with its grade and medicinal power, must be even better than those on the market.

Shaking his head, Lu Tianyu held the cool jade bottle tightly, and exhaled heavily, after an interval of three years, he was finally able to step on that level again.

After getting the Qi Gathering Pill, Lu Tianyu did not choose to take it immediately, took a deep breath, forcibly suppressed the eagerness that was tumbling in his heart, and forced himself to roll into bed to rest.

Lu Tianyu knew very well in his heart that with his current state to attack the aliens, the probability of failure would probably be more than seventy percent, although the Qi Gathering Pill was not difficult to refine for the medicine heart, but he didn't want to take such a senseless risk.

Seeing that Lu Tianyu was able to resist the temptation of breaking through the stranger immediately, Yao Xin nodded with satisfaction, a touch of relief appeared on the old face, and his body turned into a ray of light when he shook slightly, and got into the ring.

......

After the successful refining of the Qi Gathering Pill, Lu Tianyu's cultivation began to be unhurried and impatient, practicing on time for an hour every day, and then going to the back mountain to practice different skills, and occasionally accompanied him to still wander around Soto City, a leisurely life, and lived a very comfortable life.

And after a few days of such an easy time, Lu Tianyu finally adjusted his body state to the peak, and at this time, it was the best moment for him to impact the stranger.

Lujia back mountain, under a hidden cliff, Lu Tianyu sat cross-legged in this cave that was only more than one meter wide, this cliff was his carefully selected place to practice, opposite the cliff, the clouds and mist were shrouded, and under the clouds and mist were hidden the dangerous Demon Beast Mountain Range, under the cliff, there was a bottomless cliff, and the only path that could enter here had been covered with branches and gravel in advance, so at this time, he was very sure that this breakthrough would not be interfered with by people halfway.

Taking a slow breath, Lu Tianyu took out the jade bottle from his arms, the mouth of the bottle was slightly slanted, and a blue-green alternating pill rolled out.

Looking at the glossy and mellow surface of the gathering qi, Lu Tianyu smiled slightly, sniffed the refreshing fragrance again, licked his lips, and without the slightest hesitation, he took it into his mouth.

As soon as the Qi Gathering Pill entered his mouth, a faint cold meaning spread out in his mouth, and after a while, a stream of warm pure energy rushed directly into his body from his mouth, and suddenly, his body trembled violently.

With a calm face, Lu Tianyu's hands quickly formed a handprint to absorb the alien qi, his breathing gradually became stable, and the faint alien qi in his body moved in response to his heart, quickly entangled with the powerful pure medicinal power, and then began to refine frantically.

In the small cave, the calm air suddenly fluctuated violently, and a trace of pale white alien qi seeped out of the air, and then continuously drilled into Lu Tianyu's body.

The teeth clenched his lips, and the collision of the two energies in his body made Lu Tianyu's meridians continue to feel throbbing, but fortunately, his veins are much tougher than ordinary people, so although he feels pain, it has not caused much damage for the time being.

In the body, the alien qi was wrapped in a mass of green pure energy, and with the crazy refining, there was constantly green energy being assimilated into pale white alien qi, and with the support of these later forces, the scale of the alien qi in Lu Tianyu's body was constantly expanding at a speed visible to the naked eye.

Although the pure medicinal power is constantly refined, they seem to be endless, and every time the alien qi refines a ball of medicinal power, there will be a greater mass of green energy rushing over.

Under the refining in the body and the continuous injection of the alien qi outside the body, the alien qi in Lu Tianyu's body has gradually filled most of the veins.

The refining was still continuing, and when the follow-up power of the refined medicinal power began to weaken, Lu Tianyu, who was intoxicated by the rapid growth of his strength, suddenly discovered that the fighting qi in his body had swelled to a critical point that could not be increased.

The expansion of the alien qi directly caused Lu Tianyu's meridians to twitch gently, and the sharp pain made the corners of his mouth crack.

"Quick, condense the strange cyclone!Otherwise, it will explode!" The sound of the medicine heart's shout, like thunder, exploded in Lu Tianyu's heart.

Taking a deep breath, Lu Tianyu's handprint suddenly changed, the index thumb was handed over, the middle finger was pointed at each other, and the ten fingers formed a strange handprint, he had walked this step back then, so now he used it again, and it was also handy, and there was no jerky feeling.

With the change of Lu Tianyu's handprint, the surging alien qi in his body seemed to be subjected to a violent suction, and it contracted rapidly towards the position of the lower abdomen.

The pale white alien qi in the veins of the body all began to retreat invariably, and when all the alien qi shrank to the lower abdomen, the pale white alien qi had begun to turn milky white.

"Quick, compress the alien qi, use your soul perception to compress them, if the condensation of the alien cyclone fails, you will fall back to the eighth stage again!" The cry of the medicine heart sounded in Lu Tianyu's heart very appropriately.

Nodding slightly, Lu Tianyu condensed his mind, and his excellent soul perception instantly gained control of the alien qi in his body, and then began to compress it frantically.

Driven by the soul perception, the milky white alien qi began to resist, constantly churning violently, although the power of resistance was not weak, but Lu Tianyu's soul perception was even amazed at the beginning, so the protest of the alien qi was undoubtedly a mantis arm blocking the car, and after a slight stalemate for a while, it began to shrink helplessly.

When the alien qi contracted to the size of a palm, it froze again.

"Press again!" Yao Xin shouted.

Gritting his teeth, Lu Tianyu's eyes were tightly closed, and the soul perception that surrounded the milky white alien qi suddenly opened to the maximum, and then squeezed down fiercely.

"Bang!"

A soft muffled sound quietly sounded in the body.

With the sound of a muffled sound, the sense of resistance that made Lu Tianyu exhausted dissipated out of thin air, and he breathed a heavy sigh of relief, and his whole body fell down, his chest rising and falling violently.

Lying in the cold cave, Lu Tianyu sensed the abundant energy in his body that had been separated for four years, and a smile appeared at the corner of his mouth, and after a while, the smile gradually expanded, and finally turned into a light laugh, laughter, and even a wild laugh.
