In the factory on the outskirts of Baicheng, there are always all kinds of metal sounds in this huge factory on weekdays, and a large number of industrial civilization products are born here.

But since the end of the world, most of humanity has turned into zombies, and the factory has been completely abandoned.

Today, however, the sound of "clanging" can be heard again, and the sound of metal colliding is very crisp and pleasant.

If there were humans nearby, it would be surprising.

It's a pity that there is only a group of zombies who can watch here.

In the factory, the fine iron in Wu Sheng's hand already has the rudimentary form of a sword, and he is still constantly hammering with the back of the fire axe.

Without professional iron-striking tools, he could only use these relatively simple materials to complete his sword.

Time passed quickly, and the tireless thrashing work finally stopped, looking at the shining sword in front of him, Wu Sheng smiled with satisfaction.

"It's not bad to have such a good thing during the Qi training period. I've decided, I'll call you the Demon Slayer Sword. He muttered to himself.

At this time, no one shared the joy, but Wu Sheng didn't care, because he had long been accustomed to this kind of life in the past thousand years.

"Now that we have the weapons we have at hand, it's time to get out of here."

Thinking of this, he walked out of the factory and found the two dried corpses that he had settled before.

Unlike zombies, Wu Sheng felt that he owed something to Lei Hang and Zuo You, so as long as it was a matter of charging into battle, he would not let the corpses come out.

In the event that the body is destroyed, who knows if there will be a problem with the soul placed on it?

And without a body, how can they come back to life?

Wu Sheng habitually used his divine sense to find Zuo You, wanting to talk to her and check her situation by the way.

From the moment they walked out of the city, their state became weaker and weaker, and the previous search for metal had happened a series of things, and now it was already dark.

Now, time is precious to both souls.

But when the divine sense spread into Zuo You's body, Wu Sheng's face suddenly changed, and he was surprised to find that Zuo You's soul had begun to dissipate.

If before it was just a constant weakening, now it is really close to extinction.

With Wu Sheng's knowledge, he could judge that if he couldn't find a way within an hour, these two souls would completely perish.

"Damn, how could this be." Cursing in a low voice, his expression constantly changing, as if he was thinking of a way to deal with it.

"Life and death are fate." Zuo You's voice was calm, and she was also very aware of her current situation.

The past few days have made her feel very long.

Unlike Lei Hang, Zuo You doesn't like to sleep, even if the feeling of weakness can no longer support her to stay awake for a long time.

But the feeling of being in a long darkness, ethereal, and about to disappear at any moment was so terrible that she had only experienced it once, and she never wanted to enter that dark world again.

"Why is it so fast, damn it!" Wu Sheng was still cursing, as if he was complaining about the zombie virus, and it seemed to be something else.

Zuo You didn't react, she resigned herself to her fate.

If you can't survive, then death may also be a good option, at least then you don't have to feel the pain of the dark world anymore.

Just when she wanted to give up, Wu Sheng spoke again, but her voice became extremely bitter.

"There's only one way to save you now."

"What's the solution?" Zuo You asked with some excitement.

To be alive, no one wants to die, and she is the same.

As long as there is a glimmer of hope, Zuo You doesn't want to give up, she is still young and has a good youth.

Even when she was insulted, she never thought of giving up her life, let alone now!

Even Zuo You still complained a little bit about Wu Sheng in his heart, since there is a way, if you don't take it out earlier, you will worry about it for so long.

Wu Sheng smiled bitterly and said, "This method is not fair to you, but in this situation, I really can't think of any better way." ”

"What the hell is the solution, you hurry up." Zuo You said anxiously.

"I know of a spell called Soul Alchemy. Through spells, I can use my spiritual power to nourish my soul, so that your and Lei Hang's souls will not dissipate, and they will become stronger and stronger. Wu Sheng said truthfully.

When Zuo You heard this, he was very puzzled: "This is a good thing, where is it unfair?" ”

"This ...... The problem is that as long as this spell is used, the soul that I have nurtured will bear my mark. From now on he will be my servant, and he shall obey my commands all the days of his life, and you will live if I live, and you will die if I die. Wu Sheng said with some difficulty the possible consequences of doing so.

In fact, he thought about this approach for a long time.

It's just that the two of them ended up like this because of him, and they still have to be treated like this, Wu Sheng really can't bear it.

If there was a better way, he would never use soul alchemy.

But now, is there any other way?

"I don't mind." Zuo You's voice was a little ethereal, extremely weak, and the soul body that could dissipate at any time, what choice was there: "If you're sure that your method can really save me, then just do it, I'm sure you won't really treat me like a servant, right?" ”

"Yes." Wu Sheng nodded immediately, and the tone of his answer was very firm.

He is in debt for this debt.

After telling Lei Hang the same content and asking him about his choice, the answer he got was similar to Zuo You.

It's just that this former little fat man is an optimist, not only does he not have any frustration, but he is happy to say that he can completely rely on Wu Sheng's side.

Although the process was a bend, the result was still very good.

Wu Sheng let the two corpses sit cross-legged across from him, which was also a great challenge for the stiff corpses.

After several failed attempts, he had to give up the idea of sitting down and simply let the dried corpse lie on the ground.

His hands were placed on the forehead of the dried corpse, which happened to be the place where Lei Hang and Zuo You's souls resided.

A little bit of spiritual power ran down his fingers, and he continued to pour into the two souls that were about to dissipate.

This speed must not be too fast, otherwise the weakened souls will not be able to withstand the huge impact of spiritual power at all, nor can they be too slow, because they are already about to dissipate.

Fortunately, Wu Sheng once cultivated to reach the tribulation period, and he was even more handy at controlling spiritual power, and if he was a real rookie, I am afraid that these two souls would die miserably.

Carefully controlling the output of spiritual power, the divine consciousness is also constantly observing the changes of the two souls.

Gradually, he noticed that the two souls became more and more stable, and a small mark slowly appeared on their bodies.

In Wu Sheng's mind, two small humanoid points of light appeared, and accordingly, this spell similar to the deed of sale was finally completed.
