In the room, Yao Lao held the elixir as crystal clear as red agate in one hand, but in the other hand, a white flame suddenly gushed out.

With the appearance of this white flame, the entire room was filled with a bone-piercing chill, but in this chill, there was a burning sensation in Xiao Yan's body.

Xiao Yan, the famous bone spirit cold fire on this strange fire list, is no stranger, and he has even personally controlled it to refine the elixir, but this bone spirit cold fire is under the control of Yao Lao, and the power is several times stronger than when he controlled it before.

At this moment, after Yao Lao summoned the cold fire of the bone spirit, he directly threw the elixir into it.

Under the calcination of the white flames, the slightly bloated, agate-like elixir rapidly shrank in size, but the color on it became more and more vivid, and a rich fragrant smell like a fine wine buried in the earth for a long time slowly emanated from the palm of the old man's hand.

Taking a breath of the rich fragrant taste, Xiao Yan was full of excitement, and was stunned to find that when he was alchemy during the day, some of the sequelae of fatigue were really completely dissipated.

"Tsk, just smelling the fragrance of this thing, it has such a magical effect, it must have a great effect on the teacher's recovery of soul power!" Xiao Yan sighed secretly in his heart.

Next, under his gaze, although the elixir tried its best to resist the calcination of the bone spirit's cold fire, it did not play a big hindrance, and in just the past ten seconds, it completely turned into a bright red mass of droplets the size of ping-pong balls.

"Condensation!"

Yao Lao let out a low sigh in his mouth, and increased the calcination intensity again, but in an instant, the bright red droplets that were originally the size of a ping-pong ball were condensed into the size of soybeans.

"Now is it!"

After the bright red droplet the size of a soybean appeared, Yao Lao quickly withdrew the flame, raised his palm violently, and quickly slapped the droplet into the center of his eyebrows.

The bright red droplets refined by this elixir quickly submerged into the center of Yao Lao's eyebrows when they touched it, and then, a vast and terrifying soul fluctuation suddenly erupted from the center of Yao Lao's eyebrows, Xiao Yan's body flew out three or four meters away directly under the impact of this soul power, and smashed heavily on the wooden wall of the room.

"Xiao Yanzi, you're fine!"

Seeing that Xiao Yan was vibrated upside down by the soul fluctuations he emanated, Yao Lao quickly stepped forward and asked apologetically.

Standing up from the ground with one hand, Xiao Yan grinned and said very relaxedly: "Teacher, Xiao Yan's bones are very hard, what is this kind of impact!" ”

At this moment, when Xiao Yan's gaze stayed on Yao Lao's soul body, his face suddenly showed ecstasy.

In just a few seconds, Yao Lao's soul was not as illusory as before, and became much more condensed.

"Teacher, how is your soul recovering?" Xiao Yan asked with some expectation.

Hearing Xiao Yan's question, Yao Lao stroked his gray beard and said with a smile: "It's almost back to the state before the battle with that shapeshifting demonic beast!" ”

"Really, congratulations to the teacher!" Xiao Yan congratulated Yao Lao from the bottom of his heart.

"Xiao Yanzi, the teacher's soul power has recovered a little, next, it's time for your kid to refine the elixir to improve his cultivation!"

Thinking that there was still something to be done, Yao Lao directly took out a black Dading from Xiao Yan's black ring and placed it on the floor of the room, and injected the bone spirit cold fire into it, causing it to heat up quickly.

Then, a dazzling array of medicinal herbs burst out of Xiao Yan's ring and were suspended in mid-air.

At a certain moment, these medicinal materials were quickly refined by Yao Lao in order, and then fused......

Half an hour later, a rich scent of pills filled the entire room, and a round black pill appeared in the medicine pod.

"Xiao Yanzi, this is a three-grade pinnacle elixir, which can make people in the Dou Master stage steadily improve their one-star strength, you quickly take it to break through the strength!"

Quickly handed over a three-rank pill that had been refined to Xiao Yan, and Yao Lao immediately began to refine the next pill.

Xiao Yan didn't procrastinate, and after swallowing the pill, he immediately entered the cultivation state, sitting cross-legged on the ground, running the internal exercises over and over again.

At the beginning, Yao Lao's alchemy only filled the room with a rich Dan fragrance, but when it was close to the early morning, there were continuous energy ripples emitting outward in his medicine tripod, and it was obvious that the pill he had refined had changed from refining the three-rank pill at the beginning to refining the five-grade pill.

After refining a five-grade pill, Yao Lao still didn't stop, and immediately set out to prepare for refining the next pill.

And Xiao Yan, who was sitting cross-legged on the ground, after taking drugs and cultivating in the second half of the night, his cultivation at this time had just broken through to the peak of the Nine Star Dou Master.

Seeing his strength growing by leaps and bounds, Xiao Yan felt very excited in his heart, and the next moment, a fourth-grade peak elixir was suddenly picked up by Xiao Yan and then put into his mouth.

The four-rank peak pill is not as good as the third-grade pill, and the energy in it is already very close to the fifth-grade pill, at this moment, as soon as this four-rank pill enters Xiao Yan's mouth, it quickly turns into a pure medicinal power, surging down his throat, and pouring into Xiao Yan's meridians.

"Peng!"

As Xiao Yan ran the exercises, that huge medicinal power turned into countless small strands of energy and began to move rapidly in the meridians of his whole body according to a certain law, and even, some meridians that Xiao Yan had never touched were also rushed into this huge energy.

A drop of cold sweat slowly slid on his forehead, the corners of Xiao Yan's mouth twitched suddenly, and his entire face was twisted at this moment, hissing and cool, leaking out from between his teeth.

In the body, countless strands of tiny energy, with a momentum like a bamboo, savagely rushed into some tight meridians that Xiao Yan had never reached, the energy roared like a river, the tight meridians expanded rapidly, and extremely small cracks appeared on the meridian walls.

In the crack, there was a faint light sputtering out, which was a precursor to the meridians that couldn't help but expand violently and were about to explode.

Fortunately, some of the meridians that appeared cracked were quickly repaired by the power of the elixir that had been swam away for the second time, and these repaired meridians were much wider than before, and they could hold the energy that passed through at one time, which was naturally more than before.

And at this moment, a situation similar to this is happening in the countless meridians in Xiao Yan's body.
