After ransacking the medicine house, Chen Zheng slipped back to his house unconsciously and began to prepare medicine for refining his body according to what the old man of the void soul said.

Take half of each plant of Mustache Grass and Pulse Yellow Grass, chop and grind into powder.

A large iron pot is made to boil water and prepare to brew medicine.

These are not difficult for Chen Zheng, who often studies iron refining medicine, but what makes him feel most difficult is this step in between.

Stir-fry the medicine.

Stir-frying medicine is not stir-frying, anyone can stir-fry. Chen Zheng also has some understanding of fried medicine, which requires extremely strong soul power, and must use soul power beyond ordinary people to control the temperature of fried medicine.

Chen Zheng's first stir-fry soon ended in a failed paste.

Chen Zheng wiped the sweat from his forehead, chopped and ground half of the Wushu grass and veined yellow grass that he had left just now into powder, and started the second attempt.

Soon, the second attempt was also declared a failure.

He had to take out another plant of Martial Whisker Grass and Veined Yellow Grass to grind. He also secretly scolded himself for being stupid in his heart, if he had such a success rate, he was afraid that more than a dozen herbs would be used up, and he might not be able to succeed.

"Control your mind and feel the temperature. The voice of the old man of the void soul sounded, "If you feel that the temperature is high, speed up the stir-frying, reduce the contact time between the powder and the pot, and if the temperature is low, you know what to do." ”

Chen Zheng's whole mind was put into the iron pot in front of him, and he kept turning a small pinch of medicinal powder in it. What he wants to do is to fry the powder without changing its color.

After four more failures, for the seventh time, Chen Zheng finally succeeded in stirring the medicine.

"Not bad!"

The Void Soul Old Man exclaimed, because he knew how difficult it was to fry medicines, even some very talented soul masters, when they practiced stir-frying medicines, they had to go through thousands of attempts. Seven times to be able to succeed, it is simply a rare existence.

But at this time, Chen Zheng no longer had the strength to be happy, and only felt both mental and physical fatigue. A seemingly simple stir-fry medicine turned out to be so difficult, which greatly exceeded his expectations.

He made it to bed, and he wanted to sleep.

"Little one, don't be in a hurry to sleep! the real work hasn't begun yet!" the old man urged.

Chen Zheng had no choice but to drag his tired body, bring the wooden bucket for bathing, pour the boiled water into it, and then pour the fried medicinal powder into it and stir it well, take off a red strip, and enter it.

"Ahh

A moment later, Chen Zheng let out a low roar, and the mighty hot current enveloped his whole body with a rich medicinal power, making his whole body uncomfortable.

The cells around the body let out an inaudible cheer, as if the long-drought continent ushered in the rain, and the muscles that were sore from excessive fatigue slowly unfolded.

......

"After absorbing so much medicinal power, there was no obvious improvement in the realm. This little one!"

In the slightly messy room, an old voice suddenly sounded. Immediately after that, a half-human-tall figure appeared like a ghost.

At this time, the water in the wooden barrel had been restored to clear, and the medicinal power of the martial beard grass and the veined yellow grass was gone.

"Although the Martial Whisker Grass and the Pulse Yellow Grass are not panacea, the medicinal power of the combination of the two is already very fierce to the people of the Martial Realm! Absorbing these medicinal powers, even if it is a five-star cultivator in the Martial Realm, the strength will be improved! It doesn't work against him who is a two-star in the Martial Realm! It's really not simple!" The phantom muttered to himself.

At this moment, Chen Zheng woke up from his sleep, his eyes opened suddenly, he saw the phantom in front of him, and hugged his hands to his chest reflexively.

"Who are you?"

"There's no material at all, what else is in the way!hahaha......"

The familiar laughter sounded, and Chen Zheng immediately understood that the phantom in front of him was the old man of the void soul in the Dragon Palace Weng Ring Snail.

Chen Zheng hurriedly climbed out of the barrel, put on his clothes, came to the phantom old man with a red face, and said with a fist: "I've seen my seniors!

It wasn't until he saw this phantom that Chen Zheng realized that he hadn't asked for the name of the old man of the void soul, and he felt a little rude and embarrassed.

"Sue you, you don't know!

"The younger Chen Zheng has seen the old man. ”

"I know your name, stop talking nonsense! Elder Zhi urged.

"Yes!

At this moment, Chen Zheng only felt relaxed, and after a night of soaking in the medicinal liquid, the soreness in his muscles had disappeared. He threw a punch with great interest, but found that his strength was about the same as yesterday's, and he did not improve, and said with a little disappointment: "The effect of the medicine doesn't seem to be great!"

Zhi Lao shook his head and smiled, "It's not that the medicine is not very effective, but that your martial veins are too special!"

"Damn Shi Wu Vein!" Chen Zheng scolded, he really hated the Shi Wu Vein in his body, if there was a way to pull out the Wu Vein, he would have pulled it out and beaten it ten thousand times.

"Shi Wu Vein?haha!" Zhi Lao smiled, "You are wrong! Your Wu Vein is not just as simple as Shi Wu Vein!"

Chen Zheng glanced at Zhi Lao and asked suspiciously, "Could it be that my martial vein is not a stone martial vein?"

"That's right! Your martial vein is definitely not a stone martial vein!" Zhi Lao replied categorically, and then paused before announcing in his majestic voice, "It's a double martial vein!"

"Twin Martial Pulses?!"

This word is not difficult to understand, but Chen Zheng is still stunned, there are two martial arts veins in a person's body, how is this possible?

In fact, not only Chen Zheng couldn't believe it, but even Zhi Lao also came to this conclusion after a long period of research. Even though he was experienced, he had never heard of this kind of martial vein before, so he didn't know what the name of this martial vein was, but simply named it Shuangwu Vein.

"Two martial veins, but it is not a simple superposition of two martial veins. Zhi Lao looked at Chen Zheng, who was full of incredulity, and patiently explained.

"Every time it rises to a level, it has to clear two levels, but the energy required is not only twice that of ordinary martial arts, but ten times or a hundred times, or even more. ”

Chen Zheng was dumbfounded when he heard this, it turned out that this was the reason why my strength could not be improved for a long time! Remembering that it took him seven years to upgrade from the first star of the Martial Arts Realm to the second star, he suddenly felt a sense of powerlessness.

"This doesn't seem to be any different from the Shiwu Vein!"

Elder Zhi also sighed secretly, if the original qi between the heavens and the earth is already quite thin, this extremely peculiar dual martial vein upgrade will probably be extremely difficult. Having a strong martial vein, but not being able to upgrade, it will be another tragic tragedy.

"However, it is precisely because it requires more energy to upgrade that it reserves more energy and exerts more power. Between the same ranks, you will have few opponents and be able to challenge beyond the level!"

Seeing Chen Zheng's slightly frowning brows, Zhi Lao comforted.

Chen Zheng nodded, a determined gaze shot into his eyes. No matter how difficult it is, the Twin Martial Veins can still be upgraded. The clan is coming, for the sake of my father, but also for myself, I must fight!
