Not long after Shu Tianyu came out of the customs, District Chief Long came to visit, it was for the Yin Yang Ball, and the reason why he came out was that he knew that he had a little friendship with Shu Tianyu.

"District Chief, but you're busy, the beast tide has just ended, you should have a lot of things, why do you have time to visit me?"

After inviting the other party to sit down, Shu Tianyu asked out loud.

"No matter how busy you are, you have to come here, there is something important to find you this time, it is about the yin and yang ball, the above wants your refining method, what conditions do you want, you can mention it!"

The head of the dragon district is very generous.

His friendship with Shu Tianyu is good, naturally he will not pit Shu Tianyu, as long as he can do it, he will never postpone it.

"District Chief, this refining method is not difficult, you can hand it over, so let's do it, as long as the above provides me with a million copies of the Yin Yang Ball refining materials, this refining method will be given to you."

The value of this million materials is quite a lot, most of them are fourth-order materials, and only a few are fifth-order materials, but they add up to a lot.

No matter how few fifth-order materials are in each material, after a million copies, it is an astonishing number.

If you rely on the Heavenly Warband to collect it, it will also take a lot of manpower and material resources. ，

"A million copies, can you show me the materials I need first?"

District Chief Long groaned for a moment, and then said out loud.

There is no shortage of official materials, but he also needs to determine what materials are, and it is impossible to agree directly.

Although he knew that Shu Tianyu would not cheat him, what he represented at the moment was not himself, but the official, so naturally he couldn't be casual.

"The refining method will be handed over to you, and it is naturally impossible to make false reports on the materials, that's all, mainly there are a small number of fifth-order materials, but they are not popular materials, so it shouldn't be a big problem."

While Shu Tianyu spoke, he also projected the required materials.

"If it's just these materials, I can directly agree to them, and we have a lot of them."

District Mayor Long said happily.

The Demon Spirit Army has been stationed in the barbarian realm for decades, and the various materials harvested are naturally a lot, and many materials are piled up and not used.

It was also a waste in the warehouse, and now that he can make full use of it, he is naturally happy.

"Well, just a million copies of materials are enough, because this refining method is a bit special, and after refining the props, you still need to input energy to complete it."

"The reason why the Yin-Yang Ball is called the Yin-Yang Ball is because I have entered my own Yin-Yang Divine Fire, with a trace of the power of the Yin-Yang Law, so the power is infinite."

"After the method of refining is handed over to you, you also need to find a strong person in the law realm to input energy, as long as there is a trace of law power, the power will not be weak."

Shu Tianyu briefly explained the reason.

In the final analysis, this yin and yang ball has such a great power, the key is the yin and yang divine fire he inputs into it, if there is no yin and yang divine fire, the power will be reduced by at least half.

"I see, I see."

District Chief Long suddenly realized.

However, he also knew that this refining method would definitely not be simple, after all, refining props that could seal the power of the law would definitely not be bad.

Otherwise, the power of the law will directly destroy the props, and it will not be able to seal them.

Besides, there is no shortage of masters in the official, and arranging a person to help refine the yin and yang ball is nothing at all.

"Depending on the input energy, the name can also be different, but as an offensive item, it is best to input lightning type, fire type and other super lethal energy."

Shu Tianyu thought about it and said out loud again.

"Well, I understand, I'll let people send the materials over, and we will deliver them with one hand and the refining method with the other."

District Chief Long said again.

"Don't be so troublesome, I can give you the refining method now, and after you go back, just let someone send it."

Shu Tianyu smiled slightly.

"Okay, okay!"

District Chief Long nodded.

Then he got up and took his leave, he still had a lot of things on his body, and after the business was done, there was no time to stay longer.

That night, a million copies of the refining materials were delivered.

Shu Tianyu also directly sent the materials to the workshop of the war group and handed them over to the personnel refining the yin and yang balls.

Of course, now refining is not only the yin and yang balls, but also the thunder beads.

After the Heavenly Tribulation Thunder was upgraded to the Heavenly Dao Tribulation Thunder, the power increased greatly, and the attack power was already comparable to the first level of the Law Realm, and the lethality was full, so Shu Tianyu naturally used it for the first time.

Therefore, with this million copies of the material, Shu Tianyu plans to use half of it to refine it into a thunder bead.

……

At the same time, the high-level members of the Federation who had obtained the method of refining the Yin and Yang Ball also took action, and after research and improvement, they developed multiple versions.

The weakened version is replaced with third- and fourth-order materials.

The enhanced version is replaced with fifth- and sixth-order materials, and the refined props can exert the power of the high-level of the Law Realm.

It's just that the number of enhanced versions is not much, and only a small amount can be refined.

The focus is still on the weakened version, the props refined from third- and fourth-order materials, the power has also reached the late fifth-order stage, and the equipment for the ordinary demon spirit army can be said to have greatly enhanced the military strength.

"Great, with some of these offensive props, you won't have to worry about the beast tide in the future."

Many of the demon spirit armies who got the props were excited.

In the following month or so, the Demon Spirit Army also attacked everywhere, using offensive props to clear the way and clean up the brute beast groups around each fortress.

All the threatening brute beasts were directly killed, and what was left behind was basically a herbivorous brute herd.

……

At the same time, the barbarian side has also made progress, and the high-level of the Federation and the Nine Emperor Princes of the Barbarian Divine Court have reached a cooperation and signed a cooperation contract.

Now that the human race is in the territory of the Nine Emperor Princes, they can be protected by the Nine Emperor Princes, and as long as they do not violate the territorial system, there is basically no danger.

However, the Nine Emperor Princes are in the Ninth War Zone, and if you want to enter the territory of the Nine Emperor Princes, you must first teleport to the Ninth War Zone.

After signing a peace agreement with the Nine Emperor Princes, the Ninth War Zone is basically safe, and the only thing to pay attention to is the brute beast clan.

"Book boss, I'm here again!"

At noon that day, District Chief Long came to visit Shu Tianyu again.

Because of Shu Tianyu's relationship, he has also made great contributions, although his position remains the same, but his level has been improved by one level.

For Shu Tianyu, he was naturally very grateful.

In addition, there are a lot of good things in the Tianyu grocery store, so after he is free, he will come to the Tianyu grocery store from time to time to take a look.

"Come here, make your own tea and drink it, don't let me do it every time."

Shu Tianyu didn't raise his head, and continued to write his appraisal results.

Now that District Mayor Long has come over for the first two days, he is already a frequent customer of the Tianyu grocery store, he is too familiar, and he gets along a lot more casually, not as regular as he did at the beginning.

"Hey, hey!"

District Chief Long smiled, went directly to the coffee table and sat down, brewed a pot of hot tea, and then sat down to taste it.
