Liu Zhengyang knew very well that even if new materials were developed, it would be unrealistic for the whole people to be armed.

The characteristics that new materials have to bear have destined that the main body of research and development of new materials is a scarce resource.

Therefore, Liu Zhengyang can only find another way.

The first is to use the city defense system for defense, although this will consume a lot of resources, even spiritual stones, but in the face of life, such consumption is completely worthwhile.

According to his expectation, this city defense system is a huge tortoise shell, which directly envelops the entire city in order to resist the attack of the Black Soul.

But it is not Liu Zhengyang's character to be passively beaten.

This is the second point he thought of.

After the new material is developed, it is destined to give priority to the strong, especially the strong at the Taoist level. If there is sufficient protection, the effect that can be played is too great!

While fully ensuring their safety, the impact on the black soul will be a devastating disaster.

Of course, it's just Liu Zhengyang's vision right now.

But the research and development process must be carried out at the same time.

Even Liu Zhengyang is more inclined to the former.

After the emergence of the city defense system, there will be further space for the research and development institute to study new materials.

There are still Dao Source Realm experts here who will certainly not stand idly by. At that time, they can also form a certain impact on the black soul, and can be slightly resisted.

Coupled with the backing of the city defense system, the Dao Origin Realm powerhouse is tired from killing, so you can come back to rest!

Why was the Dao Source Realm strong in the first place sealed by the Black Soul?

It wasn't because there was no chance to fix it, and he was fighting almost all the time until he was exhausted.

Had to be sealed by the black soul.

If there is a chance to repair, not only physical fatigue can be repaired for them, but it also means that their minds will not be as depressed as they used to be!

"Especially the city defense system, we must catch it the first time! Even the simplest version that comes out first is acceptable!"

Hearing Liu Zhengyang's words, Tang Yuting knew where the focus was next.

Now his eyes were firm and he said: "Understood, Brother Yang, I will find someone to practice!"

Tang Yuting hurriedly left.

But Liu Zhengyang's brows were locked together.

The visit of Venerable Changjian made Liu Zhengyang a little surprised.

"Did something happen in Kyoto?"

Liu Zhengyang hurriedly asked after seeing him.

Venerable Changjian shook his head, and then hesitated and said, "Everything is stable on the Kyoto side, but everyone is a little worried about Dianzhu Liu's affairs!"

Liu Zhengyang thought about it for a while, but didn't hide it.

It was just a solemn exhortation: "What I want to say next must not be spread, otherwise it will cause further panic! But you can know about the Temple of the Guardian or the powerhouse of the Taoist level!"

After Liu Zhengyang finished speaking, he told the story of the black soul.

Venerable Changjian couldn't help but his face changed drastically.

"What? There is such a thing!"

After speaking, Venerable Changjian felt that his spirit had been greatly impacted, and he couldn't help but glanced at Liu Zhengyang deeply: "Dian Master Liu, this matter is not trivial. I think it is safer for the elders in the temple to come here in person!"

Liu Zhengyang thought for a while and nodded.

The matter of the black soul cannot be disclosed for the time being. This may cause widespread panic, but the powerful Daoist will be the main force in the next fight against the black soul. They know in advance that the research on new materials will also greatly promote the research. significance.
