After bathing in the starlight and moonlight after a night of cultivation, Chen Zheng felt that his soul was extremely comfortable, and his soul body was more condensed than before.

When the moon fell, Chen Zheng's soul returned to his senses and ended his cultivation of the "Star and Moon Treasure Body", and the whole person felt refreshed.

After a while, dawn came. Dai Sanjin finished his cultivation and was successfully promoted to the Nine Stars of the Earth Martial Realm, thanking Chen Zheng with joy on his face.

"Hurry up and give me the Dharma Protector, I will also be promoted to the Nine Stars of the Earth Martial Realm!" Chen Zhengpan sat down, took out a Di Yuan Dan and swallowed it.

He had already taken a Diyuan Pill, and taking the Diyuan Pill again had no effect, which he had also personally verified.

But he didn't hesitate to take one.

Because he took this Earth Yuan Dan, it was not the Nine Star Pass of the Earth Martial Realm that broke Chen Tianxin's seal, but the Nine Star Pass of the Earth Martial Realm of another martial vein.

Chen Zheng has two martial veins, except for a few people such as himself, Zhi Lao, Chaotian Holy Maiden, Baguio and so on, no one else knows, and Chen Tianxin doesn't know either.

The Nine Star Pass of the Earth Martial Realm that was sealed by Chen Tianxin was only one of Chen Zheng's two martial veins, and the other relatively hidden martial vein was not sealed.

Previously, Chen Zheng had been gathering his strength to break Chen Tianxin's seal, but after countless attempts, he even ventured to guide Yan Pan's attack into his body to crack it, but it did not work, and Chen Zheng decided to let it go for the time being.

First break through the martial veins that have not been sealed to the nine stars of the Earth Martial Realm, and improve the cultivation strength to a higher level, and then slowly study the problem of sealing.

The Diyuan Pill entered the body, turned into pure medicinal power, and was guided into the Nine Star Pass of the Diwu Realm that had not been sealed. This martial vein had never had the medicinal power of the Diyuan Pill entered before, so there was no situation where the medicinal power was transformed into original qi.

The pure medicinal power of the Diyuan Pill turned into thousands of small worms, and it quickly disintegrated the blockage in this aperture, and the aperture poured into the original qi and slowly brightened.

"Half-step Earth Martial Realm Nine Stars!"

For a martial artist who only has one martial vein, if he has opened the key to the Nine Stars of the Earth Martial Realm, it is the cultivation realm of the Nine Stars of the Earth Martial Realm!

But for Chen Zheng, who has two martial veins, it can't be regarded as a real promotion to the Nine Stars of the Earth Martial Realm, but only half of the Nine Stars of the Earth Martial Realm can be regarded as a cultivation realm.

Chen Zheng ran the "Nine Heavens and Stars Jue" a few times, completely stabilized the half-step Martial Realm Nine Star Cultivation Realm and walked straight away, sighed secretly, and opened his eyes.

Dai Sanjin, who was protecting the Dharma on the side, looked at Chen Zheng like a ghost, and said in surprise: "It's over? You have already cleared the Nine Stars of the Earth Martial Realm?"

Chen Zheng nodded, he didn't say that he had only advanced to the Ninth Star of the Half-Step Earth Martial Realm. Because he can't let more people know that he has the "Heaven and Earth Supreme Twin Dragon Veins", even the best brothers, not either!

Knowing some secrets may lead to death, but it is safer not to know! Chen Zheng did not want to share secrets with his good brothers, but for the sake of his good brothers' safety.

"Damn! No!" Dai Sanjin's chin almost fell to the ground, "This is too fast, right! I used the Earth Yuan Dan to break through to the Nine Stars of the Earth Martial Realm, but it took a whole night, and you actually took an hour to complete it!"

Dai Sanjin said, circled around Chen Zheng twice, and didn't find anything unusual, how surprised, "It's so perverted! You guy! You are the rhythm of throwing me a few streets!"

"Brother, this is called accumulation and thin hair!" Chen Zheng grinned and looked at Luo Fei, who was still cultivating with his eyes closed, "This is your sister-in-law, help my brother watch it, I'll go out." ”

"Sister-in-law?"

Dai Sanjin had long seen that the relationship between Chen Zheng and Luo Fei was not ordinary, and he wanted to ask several times, but he couldn't help it when the words came to his lips. Even if he hadn't asked, he had already guessed an idea. Therefore, at this moment, Chen Zheng asked him to call his sister-in-law, he was not surprised, but pretended to be surprised.

"Isn't Mi'er a sister-in-law?Why did you run out of a sister-in-law again?" Dai Sanjin's eyes rolled, his expression exaggerated, "Chen Zheng, you mess around like this, I can't explain to Mi'er's sister-in-law when I go back!"

"Just say it's the second sister-in-law!" Chen Zheng waved his hand and walked out the door.

"Second sister-in-law, okay! Listen to what you mean, you have to get a third sister-in-law, a fourth sister-in-law, a five, six, seven, and eight sister-in-law!" Dai Sanjin smiled evilly, and when he saw that Chen Zheng had already walked out of the dormitory door, he shouted, "Where are you going?"

"Refining Hall!"

Out of the small courtyard, Chen Zheng went straight to the refining hall.

When he first came to the Yellow Courtyard, he came to the Refining Hall to refine the three-grade sword in exchange for cloud value, and the old man of the Refining Hall asked him to help refine a four-grade sword.

At that time, he had just been promoted to a fourth-grade soul master, and he didn't have the certainty of successfully refining the fourth-grade sword, so he didn't help for the time being. But he didn't forget about it and kept it in his heart.

Seeing that the one-month trial period is coming to an end, there is no time to help out. Therefore, after he was busy with his work, he immediately rushed to the refining hall.

Now that he is a fourth-grade intermediate soul master, his control and mastery of soul power has reached an unprecedented height, and he is able to launch fifty soul power flying needles at the same time. Moreover, the original qi cultivation has also been promoted to the half-step earth martial realm nine stars, and there is a more abundant original qi reserve.

Although, in his current state, he didn't dare to say that he had 100% success in refining a four-grade sword, but the chance of success was much greater than before.

The refining hall was still the same as it was, and even the old man who closed his eyes and recuperated was still the same, and when he saw him come in, he didn't raise his eyes, as if he hadn't heard anyone come in.

Chen Zheng didn't make a sound to disturb the sleeping god, although he was here to help the latter refine the four-grade sword, but before the refining was successful, no matter how much he said, it was nonsense.

Compared with the sword spectrum of the four-grade sword refining, Chen Zheng took out the same materials as he needed: a hundred refining steel, a five-hundred-year-old peach charcoal, and a fourth-order snow field silver snake beast crystal.

These three materials are really the three materials for refining this four-grade sword called "Cold Cloud Sword".

Although there are only these three materials for refining the "Cold Cloud Sword", each of them is a rare and scarce resource in the world, and ordinary people have never even heard of it, let alone know where to look for it.

In particular, the fourth-order Snow Plains Silver Snake Beast Crystal, which is not a martial artist with a five-star cultivation level or above in the Heavenly Martial Realm and a soul master above the fourth-rank intermediate level, cannot be obtained.

Because the fourth-order snow field silver snake lives in the cold ice and snow, its whole body is silvery white, and it is not easy to find. And it is extremely fast, coming and going without a trace, plus two deadly fangs, it is terrifying, it is a kind of monster beast with a far-reaching reputation, known as the title of the Snow Death.

Speaking of these materials for refining the four-grade sword, Chen Zheng also had to thank Yang Haoyu, Yang Haotian, Ji Hongtao and others, especially Ji Hongtao.

Because these materials were not found by Chen Zheng himself, but obtained from Yang Haoyu, Yang Haotian, Ji Hongtao and others.

Ji Hongtao is the pride of the sky of the ancient clan of the Ji family, and he is also a four-grade soul master, and he has stored a considerable amount of scarce materials, including the materials for refining this "Cold Cloud Sword", which must have been prepared by him for refining the four-grade weapons.

Chen Zheng put out the three materials needed to refine the "Cold Cloud Sword" in the same way, so that it would be convenient to refine and purify them for a while.

There are a little more hundred refined steel and five-hundred-year-old peach charcoal, but there are only two fourth-order snow field silver snake beast crystals.

In other words, Chen Zheng only had two chances, and if he couldn't succeed twice, he wouldn't be able to refine the four-grade sword this time.

Chen Zheng carefully recalled the refining method on the four-grade Hanyun Sword refining sword spectrum several times, and understood every detail, leaving no ambiguity.

Only then did he begin to refine three materials, and the first one he refined was five-hundred-year-old peach charcoal, because this material does not need to be refined by flames, it only needs to be ground into powder, and the smaller the particles, the better.

Chen Zheng put a sufficient amount of five-hundred-year-old peach charcoal into the sword refining furnace, urged the original qi to blast it into powder, and bombarded it hundreds of times in a row to ensure that it turned into a fine powder that could not be finer before stopping, wrapping it with soul power and putting it aside.

After that, he began to transfer gas to raise the fire and preheat the sword refining furnace.

After the entire sword furnace was evenly heated, Chen Zheng's soul power quietly gushed out, wrapping a fourth-order cold snake beast crystal and sending it into the sword refining furnace.

The fourth-order Snow Plains Silver Snake Beast Crystal entered the furnace, and Chen Zheng immediately controlled the input of the original gas to keep the fire low and low temperature. Although the beast crystal of the Snow Plains Silver Serpent is a fourth-order, it does not eat large fires, and can only burn slowly on small fires, and once the fire is large, it will explode immediately.

"Hiss ......"

Between the slow fire refining and burning, silver cold qi burst out from the fourth-order Snow Plains Silver Snake Beast Crystal, as if small Snow Plains Silver Snakes were impacting everywhere, hideous and fierce.

This fierce cold qi is exactly where the essence of the fourth-order Snow Plains Silver Snake Beast Crystal lies, once it is lost, the refining will be declared a failure.

The soul power immediately wrapped up layer by layer, but these cold qi were extremely fierce, and they penetrated several layers of soul power in an instant.

"Wrap it again!"

The soul power was immediately wrapped again, and I don't know how many layers it wrapped, but it is estimated that it took more than a thousand layers to seal these cold airs.

Chen Zheng was secretly glad that if he hadn't advanced to the intermediate level of a fourth-rank soul master, he really wouldn't have been able to stop this fourth-order Snow Plains Silver Snake Beast Crystal.

After sealing the fierce cold air, Chen Zheng quantified it into a white liquid, as white as snow, as white as milk, full of a trace of spirituality.

After carefully wrapping it in his soul, Chen Zheng breathed a little, and then began to refine the refined steel. In this way, there is nothing special about the material except that the melting temperature is very high.

But he didn't expect that the temperature of smelting this material was ridiculously high, even with Chen Zheng's half-step Earth Martial Realm Nine Stars' original qi reserves, it was also powerless. He had to refine and absorb the original qi while exporting the original qi.

Fortunately, he comprehended some of the mysteries of the Nine Heavens and Stars Technique, and each key turned into a whirlpool, efficiently refining and absorbing the original qi between heaven and earth.

A huge suction force radiated from Chen Zheng's body, constantly spreading outward, spreading out of the lecture hall, spreading out of the Yellow Courtyard, and spreading to the mountains and rivers and clouds with rich aura.

The wind, quietly formed, blows the white mist and shakes the canopy.

The original gas is continuously gathered, and after the transformation of Chen Zhengwu's vein, it is continuously exported.

The temperature in the sword refining furnace continued to rise, and the entire sword refining furnace became red, and the temperature in the sword refining hall also increased.

The old man behind Chen Zheng, I don't know when, had already opened his eyes and looked at Chen Zheng with a little surprise, "This little guy is really not simple!"
