Gu Qingfeng suddenly stretched out his white and powerful palm and entered the distorted space.

When he pulled his hand out again, there was a yellowed ancient book in his hand.

There were only five big characters written on the cover of the ancient book: [One-word Zhu Yin Sword].

Gu Qingfeng was slightly surprised. Yizi Zhuyin Sword? What does this name have to do with Yizi Fenyang Sword?

With a slight curiosity, Gu Qingfeng couldn't help but flip through it.

at the same time......

In a mountain forest hundreds of miles away from Wutong County, Li Qianren had just dealt with the Wild Dog Taoist of the Blood Demon Cult. He was wearing an unstained robe, holding a bloody dog ​​head in his hand, and his face was grim.

Suddenly, Li Qianren's expression changed, and his gloomy eyes stared in the direction of the Demon Suppression Division.

"How is this possible! The space restriction I set up was actually broken! Is there something wrong on the third level of the Demon Suppression Prison? Oh no! The Yizi Zhuyin Sword! And the Blood God Son!" Li Qianren's face changed drastically. He looked at the dog head in his hand and instantly figured out the cause and effect.

No wonder the monster from the Blood Demon Cult has been acting so abnormal these days. He is actually trying to lure the tiger away from the mountain!

Fell into a trap!

Li Qianren was anxious and his face was extremely gloomy. He suddenly exerted force and stepped on a deep pit. With the help of the recoil force, his body instantly rose into the air and flew towards Wutong County.

Compared with the Blood God Son, he was more worried about the Yizizhuyin Sword, because the Blood God Son was locked by hundreds of restrictive chains, and the restrictive power of that level could not be removed even if several innate masters worked together for several days.

However, the Yizizhuyin Sword is different. The space restriction he set up is only secret, but very fragile. After all, the power of space is extremely mysterious and difficult for mortals to control. It is already a genius for Li Qianren to be able to use it, not to mention the quality.

On the way, his brain was working rapidly, and some clues from the past came into his mind.

He thought of the mysterious innate master of the Blood Demon Cult who had appeared on the outskirts of Wutong County. He combined the White Bone Demon Fire with the Yizi Fenyang Sword and destroyed an entire mountain to demonstrate to him.

At that time, I saw through his plan and understood that the man's goal was the Yizizhuyin Sword, so I deliberately did not look at the hiding place of the Yizizhuyin Sword. Later, that man really disappeared.

But he didn't expect that after such a long time, he actually found the Yizizhuyin Sword!

Damn it!

I clearly saw through his plan and didn't even look at the Yizizhuyin Sword. How did he find the hiding place?

Suddenly, Li Qianren had an idea. When you can't find the thing anywhere, and there is a forbidden place that no one is allowed to enter, even a fool can guess that the thing is in the forbidden place.

And this forbidden area naturally refers to the Demon-Suppressing Prison.

Being too clever may lead to mistakes!

........

After Gu Qingfeng finished reading the Yizi Zhuyin Sword, he suddenly realized that this martial art was actually paired with the Yizi Fenyang Sword. The combination of the two could form a heavenly-level martial art, the Cross Nether Flame Sword!

The nature of the Yizi Zhu Yin Sword is completely opposite to that of the Yizi Fen Yang Sword. If the Yizi Fen Yang Sword uses yang fire, then the Yizi Zhu Yin Sword uses yin fire.

What is Yin Fire?

It is a flame that is completely opposite to the hot nature of flames. Normal flames will increase the temperature, but Yin Fire does the opposite and lowers the temperature.

The Yizizhuyin Sword is more powerful and its grade has reached the middle level of the earth grade.

The only pity is that these two sword techniques lack the most crucial part, so they cannot constitute a heavenly-level martial art.

The most crucial part is the fusion of yin and yang.

When the blazing Yang Fire and the icy Yin Fire combine, the fusion of Yin and Yang will produce a huge energy reaction, and this energy reaction is the key to heavenly-level martial arts.

Seeing this, Gu Qingfeng suddenly had an idea. Although there was no method to blend yin and yang, its essence was the fusion of yin fire and yang fire, that is, the fusion of flames. Doesn't that mean that he can use his fire-controlling talent to forcibly control the fusion of the two without the need for any method?

Gu Qingfeng was slightly excited when he thought of this, but the specific situation still needed to be tested. Before that, he needed to find a Yin Fire first.

After putting away the Yizizhuyin Sword, Gu Qingfeng used the teleportation technique to leave the Demon Suppression Prison. The fight with the fox spirit just now was quite loud and some demon hunters had been alarmed.

As soon as Gu Qingfeng left, a dazzling beam of light shot out from the Demon Suppression Bureau, tearing through the darkness and shooting towards the sky.

For a moment, the entire Demon Suppression Division seemed as bright as day.

That was the magic mirror sensing the breath of the Blood God Son and starting to sound the alarm.

As this beam of light appeared, at the same time, the Demon Suppression Offices in the four directions of north, south, west and center of the Great Yan Dynasty also shot out beams of light, which echoed the light beam of the Demon Suppression Office in Wutong County.

At this moment, countless demon hunters were awakened. Looking at the light of the magic mirror, they understood the cause of the matter. This was a sign that the Blood God's Son had been kidnapped.

All of a sudden, the Great Yan Dynasty's Demon Suppression Department headquarters began to issue emergency orders one after another, mobilizing countless demon hunters to prevent the Blood Demon from reviving.

At this time, the culprit, Gu Qingfeng, was enjoying the gift from the demon from outside the domain.

At the beginning, he swore an oath according to Pu Yao's request, which was to go to the third level of the Demon Suppression Prison to devour the Blood God Son, but now Gu Qingfeng has broken his oath.

Because he did not swallow it, but brought out the Blood God Son.

Of course, all this was done intentionally by Gu Qingfeng.

When Gu Qingfeng saw the magic mirror of the Demon Suppression Bureau shining brightly, he finally understood why Pu Yao repeatedly emphasized that he must devour the Blood God Son instead of bringing him out.

It turns out that the Blood God has a magic mirror watching him. Once the formation that isolates the aura is broken and the Blood God leaves the Demon Suppression Prison, the magic mirror will give an alarm.

But at this moment, Gu Qingfeng had no time to think about anything else.

The string of the Demonic Blood Oath wrapped around him moved!

At the end of the line that connected to the void, a supreme and great being seemed to appear. He looked at Gu Qingfeng indifferently, holding the line in his hand.
