After being reminded by Zhang Chen, Lu Bu did not make a mistake this time, and brought back the four-headed male Eastlong to Zhang Chen.

Zhang Chen drew blood from Eastron, who had fainted, and a large container full of it was enough for Zhang Chen to soak his hands and enhance the tolerance of his hands.

However, soaking hands with dragon blood is just a prelude, allowing the hands to gain a certain amount of tolerance, just to prepare for refining more drugs later, layer by layer, and constantly enhancing the strength of the hands, until finally successfully quenching the first turn of the star picking hand.

That is to say, in order to practice the first turn, more materials are needed, not just one material, different materials need to be tempered repeatedly, and the time span of this is at least a few months.

As for the effect, you have to try it to know.

Zhang Chen believes that the increase in the skill of picking stars will not be low, after all, the description in the novel is the top ten supernatural powers, which is credible.

"Let's go, go home!"

After returning home.

Zhang Chen poured the dragon's blood from one of the large containers into the large basin, added anti-coagulant materials, and put his hands into the blood to soak.

Feel the burning and pain coming from your hands.

Said that the good Eastron blood is relatively mild, so it is suitable for soaking hands?

Zhang Chen was a little slanderous, but after thinking about it, he could understand it, after all, to temper the tolerance of his hands, he had to go through pain to transform, and this pain was already very light.

While refining his hands, Zhang Chen also took out the book "Seven Absolute Swords" and asked Lu Bu to help him turn the page while looking at the content on it.

Now that Zhang Chen's cultivation of the Seven Absolute Swords has reached the fourth layer, he is able to impart condensed aura to consciousness.

And on the fifth level, the difficulty again crosses a level.

The fifth layer of the Seven Absolute Swords, Kenshin!

The so-called sword heart is the heart of a sword. Take the body as the sword, and the will as the sword.

If you can reach the realm of sword heart, you can achieve the unity of man and sword.

Zhang Chen felt that something was amazing.

"Condense the sword gang around the body to form a sword gang shield, which lasts for seven seven and forty-nine days, so that the sword gang will be further transformed and stratified, and it can be theoretically divided into two layers, one is the sword heart layer, and the other is the sword gang layer. Once layered, the sword will be formed from the heart of the sword, and there is no longer a need for deliberate cohesion. ”

Zhang Chen looked at the description above.

"This description is kind of like, let the muddy water sit for enough time for it to layer up?"

He still couldn't understand the meaning of doing this, why it was layered, and what the Kenshin layer formed inside meant.

Could it be that if you persistently condense the sword gang, you can form a sword heart?

Literally, if you want to explain it, maybe you can only explain it in terms of practice makes perfect.

The skill of the oil seller pouring oil without wetting the copper money is only familiar with it.

Proficiency can form skills.

If you are proficient in condensing Jiangang and can form a sword heart, then the sword heart realm should be another realm born from Jian Gang.

Zhang Chen soaked his hands with dragon blood.

Then condense the sword gang on the surface of the body.

After trying, he could only condense a few sword gangs on the surface of his body, and the sword gang was as thin as a cicada's wings, so he wanted to use this thing to cover the surroundings of his body without dead ends...... Hiss~ The difficulty is terrifying!

As soon as Zhang Chen tried, he felt deep despair, and suddenly had some discouraged thoughts.

However, what is it to grit your teeth and give up in the first place?

How to say that he still needs to soak the dragon's blood for a long time, and it is just used to condense the sword gang and cover the body surface during this time, which is regarded as a pastime.

After a long time, Zhang Chen was tired and sweating profusely.

This may be an impossible task.

"In three hours, I can only condense five sword gangs, shrouded in the surface of my body, this is already my limit." Zhang Chen sighed, "The fifth decision, it's really difficult, even if I can condense a large amount of sword gang on the surface of my body in a few years, it can't last too long, Jian Gang is a condensation of spiritual energy, and my spiritual energy is not enough to maintain such a huge amount of Jian Gang." ”

For each additional sword gang, the consumption will be more than doubled, because maintaining one more sword gang requires more spiritual energy.

In this process, Zhang Chen's willpower was also rapidly depleting, and fatigue occupied his body, making him feel sleepy.

"Knock knock......" There was a knock at the door.

Zhang Chen yawned, "Come in, the door is unlocked." ”

Zhang Yuxi opened the door and came in, and asked the strong smell of blood, "Brother, what are you doing?" ”

"I'm cultivating." Zhang Chen said simply.

"Lu Bu is also here, brother, I made your favorite minced meat and eggplant, as well as braised fish." Zhang Yuxi said.

Zhang Chen glanced at Lu Bu, "I need to hurry up and temper my hands, you can bring the food for you." ”

"Do you need to work so hard?" Zhang Yuxi asked with a sigh of relief.

"There has been an alien in Dragon City, almost destroying Dragon City, if it weren't for the abilities of various cities to respond to support, I'm afraid Dragon City would have collapsed. This world is becoming more and more unsuitable for human existence, and our vision only stays in Hangzhou, and we do not see that the outside world is constantly changing and changing more terrible things. Zhang Chen said, his worries about this end of the world have not diminished.

Although it is not unfounded, the sky falls and the tall man is on top, but he is the tall man, can he not worry?

"Oh, then let Lu Bu bring you the food." Zhang Yuxi said, also falling into a short period of contemplation.

Compared with Zhang Chen, she yearns for a peaceful survival in the apocalypse, but she also understands that a peaceful environment needs to be exchanged.

Some blame themselves for not being strong enough. Although Zhang Yuxi trained harder, his growth was still too slow.

Not long after, Lu Bu brought food.

Because his hands were soaked in the snow basin, Zhang Chen could only ask Lu Bu to help him feed him, and the scene was a little embarrassing.

Zhang Chen found that Lu Bu was not embarrassed, he looked loyal, and he could be a servant or a slave at any time.

After eating, Lu Bu cleaned up his things.

It's the middle of the night.

Zhang Chen was finally able to condense ten sword gangs on the surface of his body, and after experiencing uninterrupted condensation, Zhang Chen found that his willpower had also improved slightly, and he no longer felt sleepy so easily.

His hands were still soaked in a pool of blood.

Glancing at the time, it was already ten o'clock in the evening.

Zhang Chen asked Lu Bu next to him, "Aren't you tired?" ”

"Isn't the lord tired?" Lu Bu asked rhetorically.

"Tired, but persevere." Zhang Chen's answer is very simple, if you want to become stronger, how can you not be tired.

Others have been in retreat for several years, and they are also cultivators, although they are not yet powerful cultivators, but it is nothing to persist for a whole day.

But Zhang Chen found out that Lu Bu didn't need to sleep, this setting was the same as a zombie.

Lu Bu should have infinite life, not only does he not have to sleep, but he can also live with heaven and earth.

Even if the earth is finally destroyed, Lu Bu may not die.

"Lu Bu, you should have an infinite lifespan. If one day the Lord dies of old age and dies, where will you go? Zhang Chen was idle and bored, and suddenly asked.
