The people who were poisoned by the Chen family, although they were scattered and extremely weak, were barely able to move freely, and Chen Zheng did not need to worry about food and clothing.

Chen Zheng returned to the Chen family, and after settling down with the Chen family, he returned to his residence and began to cultivate.

After experiencing the three battles of Haitian Martial Tomb, Chen Zheng fully realized his own shortcomings, and found that his cultivation strength was still too low, and his comprehension of the sword momentum still needed to be further improved.

After summing up his experience in the battle, he was ready to start cultivating the soul power martial art "Ghost Knife" that he had memorized. And if you want to cultivate the "Ghost Knife", you must first get a soul power weapon soul knife.

"Gao Shuai is a soul master, and he is the young master of the three royal families, maybe he has a soul knife in his hand!"

Thinking about it, Chen Zheng took out the handsome ring and searched in it for a long time, but did not find the soul knife, but found a set of soul power martial arts "Shadowless Needle" and a black iron lump.

Chen Zheng put "Shadowless Needle" aside and took out the black bump. The black bump caused a slight soul fluctuation, and it was familiar. After watching it for a while, Chen Zheng suddenly remembered that when he bought "Brute Boxing" at the Black Boxing Stadium before, he bought back such a black pimple by the way.

Chen Zheng immediately took out the black pimple he had bought before from the dragon palace Weng ring snail, and compared it with the black pimple in the handsome ring, and his eyes suddenly widened. Although the two black bumps are different in size, the material is exactly the same, like iron but lighter than iron, and like wood but harder than wood.

It is absolutely impossible for a young master of the three major royal families to carry a useless black bump, what is this black bump? Chen Zheng pondered.

"Soul Iron!"

Zhi Lao's voice sounded faintly, giving Chen Zheng the answer he wanted.

Chen Zheng glanced at the vague figure that appeared in front of him, and said with some puzzlement: "You know! Why didn't you say it earlier?"

"You didn't ask!"

"Hehe, master, what is the soul iron for?" Chen Zheng asked with a smile and holding two pieces of black iron.

"This still needs to be asked!Of course, soul iron is used to refine soul power weapons!" Zhi Lao looked ignorant with hatred for Chen Zheng.

"Great!Master, you can teach me how to refine the soul knife!" Chen Zheng immediately took out the refining furnace and the broken original stone, and put on a posture of raising fire and refining the soldiers, which made Zhi Lao a little embarrassed not to teach!

"Cough!" Zhi Lao coughed, and said in his heart that he was careful with me, you are still tender, "Qi Wu Realm, there is no need to burn the original stone!"

Elder Zhi motioned to Chen Zheng to put away the broken rough stone, but Chen Zheng was confused and asked puzzledly: "If you don't burn the rough stone, what will you burn?"

"Your original qi!" Zhi Lao pointed at Chen Zheng's chest with his illusory index finger.

Hearing this, Chen Zheng's eyebrows flew high, "Master, you're not joking, right? With just my little bit of original qi, how can I burn it! Let's burn the rough stone! We have the broken rough stone!"

"If you don't want to practice, forget it!" Zhi Lao waved his hand, pretending not to be difficult for others, and paced slowly in mid-air.

Chen Zheng wanted to improve his strength, of course he wanted to practice, and immediately laughed and said: "Master, I didn't say that I didn't want to practice! Burn the original qi, burn the original qi, what a big deal! Master, let's start!"

"Okay! First of all, use your soul power to ignite the original qi!"

Zhi Lao issued a command, Chen Zheng immediately did so, with the previous experience of igniting the original stone with soul power, it was much easier to ignite the original qi with soul power, and it could be said that there was no difficulty at all.

"Poof!"

A green flame burns on the index finger, swaying and jumping, very charming.

"Don't stink! Immediately feed the raw gas into the refining furnace and increase the furnace temperature!

Zhi Lao's voice sounded, and Chen Zheng immediately urged the original qi in his body to enter the refining furnace. In the next instant, the furnace burned with green flames. After the fire burned for seven or eight minutes, the entire refining furnace was heated up, and Chen Zheng put a piece of soul iron into it according to Zhi Lao's instructions.

The raw gas was continuously fed into the refining furnace, turning into a raging flame, calcining the soul iron. Ten minutes later, his unsightly soul iron did not react at all.

At this moment, the original qi in Chen Zheng's body had basically been consumed, and he had no choice but to stop refining his troops and stop to recover his original qi.

After a short process of refining soul power weapons, Chen Zheng found that refining soldiers with original qi was also a great consumption, although it was not as fast as the consumption of the original qi in his body into the Southern Cross Star Shield, but this kind of uniform output had another benefit, that is, the exercise of raw qi output control.

In less than twenty minutes, he found that his control over the output of the original gas had improved a little compared to before.

And if a martial artist has an accurate and comfortable control of the original qi output, it will undoubtedly be able to increase the lethality of the original qi output and enhance the combat power!

It turns out that there are such benefits to refining soldiers with original qi! Chen Zheng suddenly understood Zhi Lao's painstaking efforts, and after recovering his original qi, he immediately threw himself into the process of refining the soul sword.

After consuming the original qi in his body again, Chen Zheng stopped to recover the original qi. He suddenly realized that the original qi in the room was too thin, and it was too slow to run the qi to recover, wasting time!

After thinking about it, he took out a large number of broken rough stones and spread them on the ground, and spread them half a meter thick before he felt a little satisfied with the thickened original qi in the house.

With the help of the broken rough stone, the original qi recovered several times faster than before, but Chen Zheng still felt that it was not enough, and he thought of a better way.

The next moment, he took out a blue crystal and swallowed it, what he swallowed was nothing else, it was a first-order beast crystal. When the beast crystal entered the body, it immediately turned into pure original qi and scattered in all directions, and the dry original qi in the martial veins instantly became full.

He laughed wildly and immediately sent the original qi into the refining furnace, and the flames in the refining furnace burned again. With the help of the first-order beast crystal, this time he held on for a long time, and the soul iron also reacted, slowly glowing red.

However, in the next second, the red light on the soul iron slowly dimmed, and the original qi in Chen Zheng's body was once again consumed. He had to stop again to regain his original breath.

In this way, after three days of crazy cultivation day and night, Wu Chen Zheng's control over the output of the original qi has been greatly improved, and the persistence time is getting longer and longer, the original qi in the body is thicker and purer, and the cultivation realm has quietly entered the middle stage of the four-star qi martial realm.

On this day, Chen Zheng directly swallowed a second-order beast crystal, and the endless source qi turned into flames, and after half a day, he finally burned the soul iron into a ball of red molten iron.

"Soul Control!"

Chen Zheng shouted, and his soul power pulled out a small ball of molten iron, wanting to pull it into the shape of a knife, but he didn't succeed, because refining soul power weapons is different from ordinary weapons, and in the step of soul control, you must integrate your soul power into the weapon, only in this way, it will be easy to be controlled by yourself in the future.

After failing once, Chen Zheng didn't blink an eyelid, and continued to make a second attempt, and after the second failure, he followed up with a third attempt......

The soul iron liquid in the refining furnace had been used up, and Chen Zheng had to start refining another piece of soul iron.

After talking about the basic steps, Zhi Lao has been watching from the sidelines, but he rarely speaks, even in the most critical places, he can not point without pointing. He understood that every excellent soul master had grown up through countless failures, and only by experiencing failures could he master the essence of refining.

Chen Zheng is also not arrogant or impatient, with the spirit of never giving up, constantly summing up experience in failure, constantly improving himself, and finally on the night of the fourth day, he successfully refined two soul swords.

At this time, not only did he successfully refine the soul sword, but his own original qi cultivation and soul power cultivation, as well as the control of the original qi and soul power, were all refined. Chen Zheng looked at his masterpiece with joy on his face.

The soul knife is not big, only half the size of a palm, and at first glance it looks like two darts, which is very ordinary.

Among them, there are reasons why Chen Zheng's alchemy skills are not exquisite, and there are also requirements on "Ghost Knife", what the Ghost Knife wants is to surprise and attack it unprepared, so it is easy to be small and not easy to be big.

The soul knife, the whole body is jet black, like two dark nights, and it is as light as a piece of wood to start, and it does not weigh much. Chen Zheng tried to make them fly according to the description of "Ghost Knife", but found that it was not simple.

Soul power is originally an ethereal existence, but at this moment, it is not easy to let tangible things fly! In addition, Chen Zheng is only a first-class soul master, and his soul power is still too weak, so he controls the abnormal suffering of the soul knife.

After trying for most of the night, the closest thing to success was that the soul knife jumped on the table, and it didn't fly at all, even if it was a millimeter.

The most fundamental problem is that the soul power has never been able to condense together for a long time, and the soul power is weak, and it cannot produce effective power at all.

Zhi Lao Jian yì He first cultivated another soul power martial art "Shadowless Needle" that he obtained from Gao Shuai, and learned more methods of controlling soul power, so as to better cultivate "Ghost Knife".

Chen Zheng felt that Zhi Lao's opinion was very reliable, so he took out "Shadowless Needle" and studied it.

"Shadowless Needle" is a second-grade soul power martial art, which is one grade higher than the "Sharp Conch Wave" obtained from the ghost shark Liu Hailong, and it is about a high degree of condensation of soul power and stabbing the soul of the enemy.

"Shadowless Needle" has three layers, namely the Flying Needle Outside the Sky, the Serial Needle, and the Rainstorm Pear Flower Needle, one layer is more lethal than the other, and when you practice to the third layer, you can even directly smash the opponent's soul and beat the opponent into an idiot.

After watching "Shadowless Needle", Chen Zheng broke out in a cold sweat, if it weren't for Gao Shuai who only cultivated to the first layer, in the confrontation of soul power, it would be absolutely impossible to tie, he would have died in the Haitian Martial Tomb!

He calmed down his mood, urged his soul power, and began to cultivate the Shadowless Needle. Due to his previous experience in cultivating "Sharp Nail Wave", he did not encounter much suffering when he cultivated "Shadowless Needle" at this moment, and he soon mastered it.

By the time the sky was bright, he had fully mastered the first layer of "Shadowless Needle", and he also had a basic understanding of the second layer.

The time of five days had arrived, Chen Zheng breathed slightly, stopped his cultivation, rode on the camel wolf, and went straight to the Dong Tian auction hall.

When he walked into the VIP room, he was shocked, not only Dong Qianhan and Dong Zheng were waiting for him, but there was also another person.

As soon as this person saw Chen Zheng coming in, he immediately burst out with a strong aura, and an undisguised killing intent surged out, making the air in the room irritable.

Seeing this person, Chen Zheng immediately had an ominous premonition in his heart, and instinctively wanted to turn around and run away, but thinking that his father Chen Yuanshan and others at home were still waiting for his own treatment, he gritted his teeth and walked in with his head held high.
