In front of Huo Yuhao was a simple multi-functional experimental table, on which were displayed a variety of different metals, sun needles left behind by cabbage, and a round spherical soul guide.

This is the high-temperature soul guide developed by Huo Yuhao to reproduce the Sun Martial Spirit.

To imitate the color and function of the Sun Martial Spirit, you don't need too complicated technology. You just need to continuously increase the energy output until it approaches the temperature of the ultimate fire.

But the problem now is that ordinary metal materials cannot withstand the ultra-high temperature of the Ultimate Fire. The core array will quickly melt within a few seconds and become useless.

This is the bottleneck Huo Yuhao faces in his current research, but now, there is a solution.

"He Caitou... no, Xu He."

Huo Yuhao held the sun needle with a sad expression.

The sun needle left by He Caitou provided a solution to the problem of the soul guide device's ability to withstand high temperatures. However, the senior brother who studied with him in the past has been killed by his own hands. This is one of the few things he has left in the world. Many relics.

Huo Yuhao took a deep breath and said calmly:

"Xu He, the agreement still stands. I will still help you avenge your revenge. But soon, the Sun and Moon Empire will no longer be the Sun and Moon Empire."

In addition to materials, there are also temperature issues.

Huo Yuhao kept comparing the temperature of the Sun Soul Guidance Device with the temperature displayed by Xu Tianzhen during the battle.

The temperature of the Sun Martial Spirit is second only to the Ultimate Fire. If you want to use a high-temperature soul guide to approach, it always feels a little worse, but now there is also a solution.

Huo Yuhao waved his ice emperor's claw and grabbed a handful of blazing Yangquan from the spring. He had come into contact with Ma Xiaotao, who had the ultimate fire, and he was also sensitive to changes in temperature due to his ice attribute. He was very sure that the blazing Yangquan was in the Sun Martial Spirit. above.

His plan was to put part of the blazing Yangquan into the Sun Soul Guidance Device and use the high temperature of the blazing Yangquan to simulate the Sun Martial Spirit.

The ultimate fire attribute of Blazing Yangquan is genuine, and the quality of the Sun Martial Spirit simulated by Blazing Yangquan is definitely higher than that of Xu Tianzhen.

However, new problems have arisen.

Huo Yuhao looked at the hot Yangquan in his right paw and frowned slightly.

Whether it is the cold ice spring or the blazing Yang spring, it has the most perfect ultimate attributes only when it is in the spring water. Once it is separated from the nourishment of the ice and fire eyes, and only a small handful is left, the effect will be greatly reduced.

What should we do? Do we need to empty both the Ice and Fire Eyes directly?

Huo Yuhao thought.

It is said that the Ice and Fire Eyes were conceived on the corpse of the Ice and Fire Dragon King. If the Ice and Fire Dragon Kings were made into bone dragons and placed in the demiplane of the undead, can the Ice and Fire Eyes also be transferred with them?

Yin Laixi laughed dumbly and said: "Yuhao, let's forget it. The two eyes of ice and fire have a strong breath of life, while the undead half is full of the breath of death. The two breaths cannot coexist at all."

"Well, I have to find another way."

Huo Yuhao lowered his head and thought.

This is what research is like. Once a problem is solved, you will encounter another problem after another.

At this moment, a cold and clear voice suddenly sounded from not far ahead.

"I can help you solve your problem."

Huo Yuhao frowned. The person who spoke was a blue-white fairy grass. He had seen it in the Poison Chapter, and it was called Octagonal Black Ice Grass.

The voice of Octagonal Black Ice Grass is still cold: "You want to perfectly preserve the ultimate fire attribute in the blazing Yangquan and bring out the two eyes of ice and fire. I know how to solve it."

"Say." Huo Yuhao nodded.

Star Anise Ice Grass did not answer: "But I have a condition."

Hearing these words, Huo Yuhao couldn't help but chuckle: "Okay, let's first tell you what conditions you want."
Chapter completed!
