With this keel alone, a divine blade can be forged from ancient times to the present, but in the eyes of Lao Jiu, this keel can only last for thirty seconds.

"Okay, then gather all your forces and mobilize to buy materials at a high price while making everyone bleed. ”

Dao Zhen waved his sleeves and took care of these two things alone, while Zhang Zhao and Lao Jiu returned to the Three Thousand Worlds again.

In the matter of refining weapons, pay attention to the right time and place, any wind and grass may affect the grade of the weapon, and these three thousand worlds are equivalent to Zhang Zhao's own world, so you can adjust the time and place to the best state.

After returning to the Three Thousand Worlds, Lao Jiu said while kneading the clay into balls: "In addition to the materials on the demon beasts, all kinds of iron ore and red gold are also needed, and the blood of beasts and humans must be separated, the blood of beasts is divided into birds and animals, and the blood of humans is ten years for an age group, and the blood of newborn babies and mothers when they give birth must also be separated." ”

"Then why didn't you say it earlier?"

Zhang Zhao was really taken aback, since there are so many exquisitenesses, why didn't Lao Jiu say it just now? Now that Dao Zhen has flown away, how can this be good?

But Lao Jiu looked at Zhang Zhao with a calm face, and said lightly: "Then you didn't ask me." ”

Zhang Zhao was speechless, thinking about it, it seemed to make some sense, and then he turned around and left, quickly chasing after Daozhen.

In order to prevent accidents, Zhang Zhao made a special list of Lao Jiu's requirements, and even added a few more items.

The blood of birds and animals is divided into two parts, and the bones, fur, feathers, eyes, nose, mouth, and organs are separated.

And there is basically no big problem on the human side, as long as there is no age separation for ten years.

Holding Zhang Zhao's list, the people below added fuel and vinegar to the requirements, and the requirements were more refined.

For example, the types of bones should be differentiated, the color of feathers should also be differentiated, and even the types of alien beasts should be clearly divided.

Although they didn't know what Zhang Zhao wanted these things for, in order to satisfy the leaders, these people also racked their brains and came up with as many methods as possible.

As a result, such a phenomenon began to appear in more than 100 worlds.

No matter which world it is, the cultivators all start to team up to kill the alien beasts, the strong unite to kill the high-level alien beasts, and the weaker ones go to kill the tenth-level alien beasts.

In addition, many people who were not able to kill the alien beasts also formed a team, and they were specifically responsible for dismembering and classifying the alien beasts they killed, so as to obtain a large amount of reward.

Twenty minutes later, Zhang Zhao got the first batch of materials.

This batch was collected by the cultivators gathered in Cloud City, and after careful classification, all of them were sent over.

For these materials, they are basically weighed in pounds, and all the materials together have exceeded more than 30,000 catties. Since it was to deal with the upcoming flame monsters, the cultivators would not bother with Zhang Zhao about how much it was, and some of them were even given away for free.

But in order to express his gratitude, Zhang Zhao still bought all the donated materials by catty, no matter what level, what kind of bounty of one million per catty.

If someone gets a rarer material, such as the skeleton of a divine dragon, if they want to sell it at a higher price, Zhang Zhao will buy it at the market price.

The 30,000 catties of materials were all collected by Zhang Zhao into the 3000 worlds.

It's just that why do you need so many materials, and you need a drop of everyone's blood, Lao Jiu didn't make it clear, what he is doing now is either throwing materials into the stove, or just sitting next to him and rubbing mud pills.

Although it was strange, Zhang Zhao didn't ask much.

In the next few days, Zhang Zhao bought materials outside, and when the materials reached a certain number of times, he would bring them back to Lao Jiu for refining.

As the days passed, more and more materials were devoured, but the vessel was still not filled, and the materials were consumed faster and faster, as if it were a bottomless pit that could never be filled.

On the fourth day, Zhang Zhao saw that Lao Jiu was still rubbing mud pills there, so he couldn't help but be curious and asked, "Lao Jiu, when will I be able to get out of the customs?"

Lao Jiu carefully rubbed the mud pills in his hand and said, "Wait, I'm sure you're satisfied." ”

Seeing that Lao Jiu was unwilling to be distracted, Zhang Zhao wanted to speak and stopped, but he still didn't ask anything.

It's just that the curiosity in his heart is getting stronger and stronger, and he wonders what kind of sword needs so many materials?

This time, when Zhang Zhao came back, he found that there were many Western knights and magicians outside the base, and they all brought the corpses of many high-level demonic beasts to rush over, not only that, but even cultivators from other countries brought a large amount of blood and beast bones to donate.

Just as Zhang Zhao went to thank him one by one, the red-haired Gu You walked over.

Gu You took two big bones and handed them to Zhang Zhao, saying, "This is the thigh bone of the sun god, take it and use it." ”

"Sun God?"

Zhang Zhao was shocked, thinking that this sun god was his previous general, the leader who led him to fight against the human army, and now that he took his thigh bone to refine, wouldn't he never be able to resurrect it?

"How can you resurrect the sun god with this?"

Gu You shook his head and said: "Actually, we people will not be resurrected after death, our 30,000 people are just forcibly imprisoned by their souls, so there is hope for resurrection, but the sun god they can't do this, maybe he is the same as you, I don't know how many reincarnations he has gone through and forgotten who he is." ”

Zhang Zhao put away the two leg bones and asked: "Why do I feel that Lao Jiu is becoming more and more unreliable now, I asked him not to say anything, just let me wait, but this material has exceeded 10 million catties or is not enough, if it goes on like this, when will it be a head?"

Hearing this, Gu You couldn't help frowning, and said, "Although Lao Jiu is not the best blacksmith in the demon clan, he is not far behind, he may have his reasons for doing this, since you let him forge weapons, you should believe him." ”

"Well, okay. ”

Since Gu Youdu said so, Zhang Zhao had no choice but to choose to believe Lao Jiu unconditionally.

At this moment, Liang Jing, who was dressed in a military uniform and had a capable spirit, walked over.

"Captain"

"Well, how's it going?"

Liang Jing looked at the sky and said, "Everything is ready, you can break the void now." ”

"Have you found a location?"

Liang Jing nodded and said, "I've found it, it's just above Cloud City, the distance is within one thousand to eight hundred meters, and the satellite is already aimed at that side." ”
