"Then this furnace will be placed here and continue to observe, and we will use another alchemy furnace as well. Zhu Yan said.

She took out some more medicinal materials from the medicinal herb bag, walked to the other alchemy furnace and said, "Let's refine the 'Qi Condensing Pill', this is an elixir that can greatly improve the effect of the breathing method, and it is very useful to us!"

"Refining the 'Qi Condensing Pill' is simpler than refining medicine, as long as you mash all these materials and put them in, then put in a bottle of pure water, burn it on a high fire until it is paste, and then slowly refine it over low heat until the materials become solid by themselves. Zhu Yan explained how to refine the 'Qi Condensing Pill': "Then the place full of spiritual energy is the most critical, and the medicinal materials that become solid will produce an effect of gathering spiritual energy, constantly absorbing the spiritual energy in the air, and after a long time of fusion of medicinal materials and spiritual energy, a complete spiritual elixir will finally be formed." This fusion process is relatively long, at least dozens of hours, and some high-level elixirs even take decades. ”

"Decades, how can you wait that long! Then this 'Qi Condensing Pill' should only take dozens of hours, right?" Ding Lingling said.

"Well, "Alchemy" says that it will only take eighty-one hours at most. Zhu Yan said.

"Eighty-one hours, that's more than three days, and it's a long time. Yang Xingchen said.

Wu Yaoxia pointed to the alchemy furnace where he was refining medicine just now and asked, "Then how long will that furnace take to refine just now?"

"Wait a minute, I'll go and mash the herbs, boil them on high heat for an hour to form a paste, and then slowly refine them on low heat for nine hours, and all the herbs will be refined into powder. Zhu Yan said in detail.

Then, once born and second ripe, Zhu Yan got Alchemy Furnace No. 2 on the right track and refined it for a while with the help of Yang Xingchen.

Then she smashed all the medicinal materials that had been boiled in the Alchemy Furnace No. 1 (Dragon Carving), and then continued to cook them over high heat.

The medicinal materials in the two alchemy furnaces were almost all pasted after 1 hour.

Zhu Yan turned the charcoal flames of the two alchemy furnaces into small fires, then clapped his hands and said, "Okay, the basic steps are almost all done, now as long as you keep this fire." Alchemy furnace No. 1 can be dispensed after 9 hours. Alchemy Furnace No. 2 will take 81 hours before it can produce the elixir. ”

Yang Xingchen looked at the time, it was already 10 o'clock in the morning.

The raw muscle powder of Alchemy Furnace No. 1 will not be baked until 7 o'clock in the evening.

The Qi Condensation Pill of Alchemy Furnace No. 2 will not be baked until 7 o'clock in the evening three days later.

Regarding the question of how to guard the two alchemy furnace charcoal fires, the five of them finally decided to take turns guarding them for an hour, so that they didn't have to wait here stupidly.

A lot of free time was squeezed out, and Yang Xingchen decided to practice how to control the release of aura again.

He walked to a remote corner where no one was around, spread his hands, and carefully controlled the release of the aura.

A trace of spiritual energy just came out of the palm of his hand, but it spread out uncontrollably, and he hurriedly used the breathing method to suck it back into the meridians.

Then it was repeated dozens of times, and there were a few times when that trace of aura stayed on the palm of his hand for a few seconds.

Grasping a little trick, Yang Xingchen continued to experiment and repeated it dozens of times.

There were more than a dozen times when he was able to control the aura and stay in the palm of his hand for several seconds.

There is progress, continue.

Yang Xingchen practiced alone in the corner for fifty minutes, and was finally able to control the aura in the palm of his hand for dozens of seconds every time.

"It's time to pick up Zhu Yan's class. Yang Xingchen was quite satisfied with the results of these fifty minutes of practice, and if he practiced regularly, he should be able to greatly increase the time for the aura to hover outside the body.

"What were you doing alone in that corner just now?" Zhu Yan asked when he saw Yang Xingchen coming over.

"Oh, I'm practicing controlling the release of Reiki. Yang Xingchen said weakly: "In the corner, the aura is not easy to fly away, so it is easier to absorb it." ”

"Is there any result?" asked Zhu Yan curiously.

Yang Xingchen's hands were spread out, and the palms of each hand emitted a cloud of aura.

He was showing off, and he definitely didn't release so much aura when he practiced just now.

But Yang Xingchen did control the two groups of aura very well, suspended in the palm of his hand, only slightly shaking.

Sometimes pretending is also a kind of motivation!

"Wow~ What a beautiful two spiritual power balls! flashing and flashing~" Zhu Yan said admiringly.

Yang Xingchen was very happy after hearing this, and suddenly remembered that the "me" in his dream had used his hands to send lightning to paralyze a huge black bear, and that trick looked very cool!

So Yang Xingchen's brain twitched, and he controlled his hands to slowly bring them together, so that the two spiritual power balls were close to each other, but the spiritual power balls had no special reaction.

"Do you want to stimulate the spiritual power like an aura explosion? But you can't really blast these two auras. As soon as Yang Xingchen thought of it, his actions were done.

The two balls of spiritual power gradually became irritable, and the spiritual energy continued to move and vibrate rapidly, and there was a crackling sound from time to time.

An electric arc appeared between the two spiritual power balls that were slowly approaching, and as the spiritual power rushed and the vibration accelerated, the arc became stronger and stronger.

Yang Xingchen's hands kept flashing, as if he was setting off fireworks.

"It's so beautiful! Xingchen, are you performing a magic trick?" Ding Lingling, who was in the distance, saw Yang Xingchen's constantly glowing hands, and hurriedly ran over to take a look.

Yang Xingchen couldn't help but feel a little proud, and couldn't help but increase the intensity of the aura stimulation, and the spiritual power of the spiritual power ball in his hands was several times more irritable than before!

The arcs are scurrying, and the number of arcs is exploding!

Yang Xingchen immediately felt that something was wrong! It seemed to be a little out of control!

I saw that the spiritual power balls in his hands touched each other, but immediately bounced off again, but then they touched each other again, and immediately bounced off, and the speed kept repeating this kind of collision with each other.

The speed of the impact increased exponentially, and suddenly two spiritual power balls flew out from Yang Xingchen's palm upwards!

Yang Xingchen's lowered head immediately leaned back to dodge, but it was still a little late, his eyes lit up suddenly, his face was hot, and he heard a "chirp!" in both ears.

He looked up and watched as the two balls of spiritual power burst out with lightning and shot towards the roof like a large firework......

In an instant, it hit the top of the 100-meter-high roof, and the arc was scattered!

The people standing next to Yang Xingchen all ran in the direction of the surrounding walls, so as not to be hit by something that might fall.

The people in the distance didn't know what was going on here, so they looked up inexplicably, and then looked in the direction of Yang Xingchen.

Yang Xingchen also kept looking up at the top, carefully guarding against things falling down, but after waiting for more than ten seconds, there was no response, and it was too bright to see the situation clearly.

So he ran in the direction of the lift, got on the lift, and ascended alone.

Yang Xingchen quickly reached the very top, and the originally transparent glass-like roof was now hit by the charged spiritual power ball, as if it had been scorched, showing a large black circle, about two meters in diameter.

If you look closely, it doesn't seem to be damaged, but the surface has turned black.

"It's okay, it's okay, it didn't cause any major problems. Yang Xingchen comforted himself.

Then I took the elevator back to the bottom.
