"Hope is true!" Feng Youqin stopped persuading Tang Yu to stop the research on Yin Huo Lei. She also knew that it was the worst decision to use magic instead of artillery to fight the corpses of monsters. If something more suitable could be developed, it would be the best.

Therefore, for the next period of time, Feng Youqin's heart has been seized.

From Tang Yu's side, the constant roar and all kinds of terrible explosions made the void around Tang Yu's body almost never in good condition.

If Tang Yu had not created a new power of Shengyuan at the beginning, forming a large net, interwoven in the nearby void, resisting the broken void, the fifth passage would have been completely shrouded by the force of space and time.

In the same way, because of the continuous explosion, Tang Yu's position changed from a flat to a huge underground cave.

The scope of the cave has spread to thousands of miles, and the depth is immeasurable.

At the end of each explosion, Tang Yu's body will descend to a depth, which makes people feel helpless.

"It's done!"

Suddenly, a cheering sound full of Joy came from the deep of the pit. Xuan Yunxing and others standing beside the pit were very happy. They were just about to rush into the pit. As a result, they saw Tang Yu's identity, like a purple and golden light, rushed out from the bottom of the pit.

"You see!"

In Tang Yu's hand, there was a blue and purple grenade in his hand. If it had not been for the terrorist explosions that occurred again and again during Tang Yu's research, Feng Youqin and others would not have believed that this fist sized iron pimple would have such terrifying power.

"Brother Tang, give me a try!"

Chiqiu believes in Tang Yu very much, but he wants to know more about the power of this new sound fire thunder. So he licks his face and shows a flattering smile. He comes to Tang Yu's side and says with a smile.

"Here you are! Just like the magic cannon, it can be triggered with the mind... " Tang Yu simply explained and threw the sound fire thunder in his hand to Chiqiu.

In the case of no excitation of the internal explosion contact point of the sound fire mine, the sound fire mine is quite safe, absolutely will not appear, the force of the mine attribute law and the force of the fire attribute law will directly explode after touching the acoustic fire mine.

Chiqiu is quite excited.

As a practitioner of the true realm, he is naturally eager to have the strength of the strong one.

Although he is a pure practitioner of body cultivation, although his cultivation is a pseudo true God state, his strength can be comparable to that of the real body state.

But it's just as strong as ordinary real gods.

If you are a strong man facing the four realms of the true God, you have to wait for death.

But now, just because of the fist size iron pimple in his hand, he can release the moves that are comparable to those of the four realms of the real God. Chiqiu is naturally extremely excited.

Chiqiu, who was too excited, had no response for half a day. She looked like a monkey fart.

"I said Chiqiu, what are you doing? Let's get started! Don't stand in a daze Tang Yu didn't respond to Chiqiu for a long time. He rolled his eyes and said angrily.

"I'm nervous!"

Chiqiu is very embarrassed to look at Tang Yu, red face said.

"What's so nervous about that? You're not afraid to blow yourself up, are you? " Tang Yu didn't get to the red Qiu's point of tension, speechless said.

"I..." He hesitated, and finally made up his mind. He took a deep breath, touched the explosive contact in the sound fire thunder with his mind, and then quickly threw the sound fire thunder out.

This kind of trigger type explosion point can determine the explosion time of sound fire thunder according to the number of gods used.

It can be said that under the change of Tang Yu, yinhuolei has become a time bomb. After setting out, it is quite convenient to explode when you want it to explode.

"Boom

An explosion like the earth shattering suddenly sounded from the pit.

Obviously, they are all the same explosions, but in the eyes of Feng Youqin and others, this explosion is more terrifying.

The kind of explosion that seems to be able to destroy heaven and earth and make the world collapse completely makes the hearts of Feng Youqin and others tremble.

Their faces, like Chiqiu, are very excited "tide" red, looking quite excited.

"Ha ha! Laozi can also release the powerful attack of the four realms of the true God! " All of a sudden, Chiqiu cried out with great excitement.

"Pa!"

Hearing Chiqiu's cheering, Tang Yu couldn't help but slap him on his bald head. He said angrily, "I'm so excited. This thing can only be a foreign object, not its own strength growth. I can tell you, don't rely on this thing in the future. If you really rely on it, you will be useless in your life. "

"I know, of course I know." Chiqiu was smiling, but the excited expression on his face still did not retreat.He is now extremely excited, only feel that he is really like a strong man in the four realms of the true God.

After all, there are very few people who can make such a step.

At least in the ancient temple mountain, Chiqiu has met only one night cloud haze so far.

"Tang Yu, the power of this thing is too great. It's much more powerful than magic cannon. It's not suitable for large-scale use." Feng Youqin is aware of this problem, and quickly came to Tang Yu's side and said earnestly.

Tang Yu nodded and said with some helplessness: "but there is no way. If we don't use this thing, we will need to destroy the demon beast's corpse again and again, which consumes too much resources. This is not the same thing. I have a lot of ready-made resources, and the cost of copying is too high. I guess no one in the whole ancient temple can refine it except me. "

Tang Yu has this confidence.

With the help of Hunyuan bell, he found the power of fire attribute law, the power of thunder attribute law and the stable frequency of spiritual sound stone.

Tang Yu was confident that he could not resist the explosions, let alone others.

Since they can't even resist the first step, let alone find the spiritual sound stone.

This kind of resource is unique to Tang Yu.

When he was in the land of Shenyin, he collected a lot of them and put them in the ring all the time, but they didn't use up.

This is the only thing belonging to Shenyin continent. It is almost impossible to find it in the ancient temple mountain.

As for whether he can replace the spirit stone with something else, Tang Yu has not tried at present, but even if there is such a thing, it doesn't matter. After all, those who want to copy will be directly hit at the first level!

"Lao Xuan, come and help

Tang Yu didn't have the power to understand the fire attribute law. Therefore, Xuan Yunxing stood at a distance and released the power of fire attribute law again and again according to Tang Yu's orders and integrated into the thunder fire powder.

Tang Yu doesn't have thunder powder, but it's easy to make. Even he can make a lot of it himself.

Just put the energy of thunder attribute and fire attribute into a hard enough stone, and then grind it to make powder.

That's right!

You don't see, the source of the thunder powder is this bottom end. If you grind it directly, you can get a lot of thunder powder.

But the proportion of the two is the key, which can be said to be quite important.

Not all the stones containing the energy of thunder and fire attribute can be directly integrated into the force of the law of thunder attribute and the power of law of fire attribute, and become the material for Tangyu to refine new-type sound fire thunder.
