Using True Qi to control the water vapor in the air and use it to make the container needed for alchemy is too simple and crude, but the effect is immediate.

Jade leaf goldenrod, comfrey mushroom, ginseng, creeper, sand sand, Panlong seven......

The medicinal materials for making the Rejuvenation Pill, under Chen Zongheng's instructions, Zheng Xuan added them to the pot in turn, and after half an hour, it turned into a pot of viscous liquid, emitting a very unpleasant smell of burning.

"No, doesn't the book say that it should be a bright yellow semi-transparent soup? Why am I refining it black and mushy?"

Chen Zongheng muttered, seeing that if he continued to refine, the last bit of water would be squeezed dry, so he had to collect the fire and seal the pill.

Collecting fire, as the name suggests, is to remove the real flame, which needs to be gradual, a little bit of collection, too fast or too slow, will affect the quality of the liquid medicine.

It took Chen Zongheng three minutes to put away the flames in the stove little by little, at this time he was already sweating profusely, his face was pale, his eyes were tired, and most of the true qi in his body was consumed.

There is no way, I can't control the temperature of the True Qi flame now, so I can only use this stupid method that is a waste of True Qi.

After the flame is taken away, it is necessary to solidify the liquid medicine into a solid state, which is the last step in alchemy: sealing the pill.

The so-called Feng Dan is to use its own true qi to invade the liquid medicine, and through the subtle control of the true qi, the liquid medicine is squeezed and solidified into a solid state, which is generally a round sphere, because it is the most labor-saving to do so.

This process consumes a lot of true qi, so in the era of great cultivation of immortals, some high-quality pills, alchemists will carefully seal them for a few days after collecting the fire, and only after the true qi has almost recovered will they seal the pills.

However, for the rest of the time, he couldn't afford Chen Zongheng to delay it slowly and leisurely, so he simply gritted his teeth and injected all the remaining true qi in his body into the medicinal liquid.

Immediately, Zheng Xuan saw that Chen Zongheng suddenly closed his eyes, and at the same time, a mighty and powerful momentum rushed towards the magical water pot on the stove like a stormy wave.

Zheng Xuan could vaguely feel that this seemed to be the strength of a martial artist, but there was a big difference, most of the martial artists' strength had just entered the fierce, but Chen Zongheng gave him the feeling that he was very upright and peaceful, accepting all rivers and rivers, and not moving.

Immediately afterwards, Zheng Xuan was surprised to see that the liquid medicine in the cauldron slowly gathered up, and in the end, it turned out to be seven gray-green, round and translucent pills!

"Chief, this ......"

Zheng Xuan swallowed his saliva violently, speechless in shock.

"Calm. ”

Chen Zongheng shook his head, slowly opened his eyes, his hands suddenly flipped, and the remaining true qi in the air was instantly absorbed into his body, and the water pot also turned into flowing water and fell into the stove.

Chen Zongheng grabbed the void, and the pill that was about to fall into the stove immediately flew into his palm, and when Chen Zongheng looked at it, he was immediately dumbfounded.

This......

What the hell?!

It is said in the book that the rejuvenation pill is tender yellow and fragrant.

This gray is not slippery, green is not pulled, and it also exudes a smell of coke, like some animal is not digested well, and the poop is discharged, what is it!

Rejuvenation pill is mainly used to treat external injuries and has the function of maintaining body and mind.

But these Rejuvenation Pills that he refined, Chen Zongheng was worried that if he continued to take them, not only would they have no effect, but I am afraid that they would also cause internal injuries!

"Ahem, Zheng Xuan, come here. ”

Chen Zongheng coughed lightly and waved to Zheng Xuan.

"Chief, what do you command?"

Zheng Xuan ran over and replied respectfully.

Chen Zongheng spread out his palms, placed the seven 'Rejuvenation Pills' in front of Zheng Xuan, and said with a serious face, "Zheng Xuan, you have been with me for so long, and I haven't given you any benefits, this is a new medicine I researched, and you are now fortunate to be the first person to take it on the earth, are you happy?"

"Thank you, Chief!"

Zheng Xuan's face was moved, he didn't have any doubts, and he was even worried that Chen Zongheng would regret it, so he immediately grabbed one and swallowed it on the spot.

At the moment when the pill was entered, Zheng Xuan showed a shocked look, pointed to his mouth, and said vaguely, "Chief, this medicine is so powerful, it melts in your mouth, like drinking a sip of warm water, it's just a little mushy......"

Chen Zongheng, "......"

After a minute, Chen Zongheng looked at Zheng Xuan and asked nervously, "How is it?" Do you feel any discomfort, you must tell me, because it is a new medicine, it may not be very stable......

Before Chen Zongheng could finish speaking, Zheng Xuan's face suddenly turned red, he squatted down holding his abdomen, and said in great pain, "Chief, how do I feel hot all over my body, and my stomach hurts so much." ”

"Something bad. ”

Chen Zongheng hurriedly squatted down, his fingers pressed on Zheng Xuan's pulse.

In the next second, Chen Zongheng's expression became strange.

The elixir is refined.

However, it just had no effect and did not cause side effects.

The reason why Zheng Xuan's whole body was hot and his abdomen was in severe pain was because it was contained in the elixir, which belonged to Chen Zongheng's powerful true qi!

A normal alchemist, after sealing the pill, there is no true qi in the pill, but Chen Zongheng made a mistake when he sealed the pill for the first time, resulting in a lot of true qi remaining in the pill.

When Zheng Xuan took it, these true qi would enter Zheng Xuan's body along with the medicinal liquid and invade his qi veins.

Zheng Xuan was just a five-star martial artist, and he couldn't withstand such a powerful True Qi at all, so he had symptoms of a surge in body temperature and severe pain in the position of the dantian in his abdomen.

After figuring out the reason for the matter, Chen Zongheng breathed a sigh of relief slightly, if it was a matter of true anger, it would be easy to handle, if it was the elixir itself, I am afraid that he could only exchange the antidote from the system mall at a cost.

"It's okay, a little problem, I'll cure you right away. ”

Chen Zongheng saw Zheng Xuan's face full of pain, and he also felt embarrassed, and grabbed his wrist with his right hand, about to take back the true qi in Zheng Xuan's body.

However.

That's when it happened.

Something shocked Chen Zongheng happened.

He found that the true qi in Zheng Xuan's body was now slowly decreasing, and his own qi was gradually growing.

Although this process was very slow, it was obvious that Zheng Xuan was slowly absorbing this bit of true qi and turning it into his own qi.

After thinking for a moment, Chen Zongheng looked at Zheng Xuan and said in a serious voice, "Zheng Xuan, this may be an opportunity for you, if you can bear it, it is best to wait for the symptoms to subside slowly, if you really can't bear it, then I will cure you immediately......"

Zheng Xuan shook his head, his bangs were already wet with sweat, and they were tightly attached to his forehead, he stared at Chen Zongheng very firmly, gritted his teeth and said, "Chief, no need, I'm ...... You can hold on!"

He could feel that the qi in his body was climbing rapidly.

In just two minutes, he had touched the threshold of a six-star martial artist!

It took another half an hour before Zheng Xuan slowly calmed down.

During this period, Chen Zongheng stayed by the side and did not leave an inch.

But even so, when all the true qi in Zheng Xuan's body was absorbed, he still felt as if he had walked away from the underworld, although he was not dead, he had lost his skin!

However, when Zheng Xuan opened his eyes and saw Chen Zongheng, his first sentence almost made Chen Zongheng squirt out the tea he had just drunk.

"Chief, your newly researched medicine is really awesome! I'm already a six-star martial artist now! It's just that this process is too sinful......"
