Lu Yu has been helping Mingxiu Qianye and Mingxin improve their martial souls for a long time, but he has been delayed.

Now by chance, the martial soul took part of the fragrance of the immortal medicine, and directly crossed the earth level and became a half-step heaven-level martial soul, which Lu Yu never thought of.

"With this elixir, combined with my martial soul evolution technique, wouldn't it be twice the result with half the effort?"

Lu Yu was extremely excited and fought bloodyly under lightning. Finally, he spent nine days and nine nights, successfully overcame the heavenly tribulation and took away the alchemy furnace.

Zixue and the prince in black were waiting outside. When the heavenly tribulation appeared, both of them realized it, but they did not move rashly.

Lu Yu came out, Zixue was the first to rush forward.

"Are you okay? Why have you been there for so long?"

Lu Yu smiled and said, "It's okay, there is a hidden fortune in the stone formation. You can all benefit from it in the future. Now, go to the Soul Burning Ridge first."

The prince of the Black Prison said curiously: "What luck can even benefit from us?"

"This is the elixir fire. You have refined a elixir and you will be able to use it in the future, which will be of great help to improve the martial soul."

After a few simple words, Lu Yu asked the prince of Black Prison to lead the way.

Burning Soul Ridge is located deep in the Chilian Fire Domain. The mountain is not high, stretching for more than ten miles, and it has been covered by flames.

"Just ahead, it's almost here, I've already felt the sting of the martial soul, and the soul is trembling."

The prince of Black Prison was very familiar with this place, and his eyes were filled with excitement. After many years, he finally had the opportunity to rescue his master.

Lu Yu felt his emotional fluctuations, patted his shoulder gently, and looked ahead.

A mountain that rose from the ground was like a dragon and a snake lying on the ground. Five-colored flames spewed out from the ground, burning everything, making no plants visible here. The void was filled with a terrifying soul light, which made people's souls shake and martial souls wail.

This place is terrible and can suppress all martial souls, even Lu Yu feels a little overwhelmed.

Zixue frowned and said, "What a terrifying Soul Burning Ridge, it is indeed well-known and makes people panic."

The prince of the Black Prison said bitterly: "I have tried to enter dozens of times, but every time I am seriously injured and have to turn back halfway. I am really useless. I can't save my master!"

Lu Yu looked at the surroundings and whispered: "Take us around the Burning Soul Ridge for a first time."

The prince of the Black Prison said in confusion: "Why is this?"

Lu Yu said: "First check the surrounding environment to prevent gods from staying in this place and waiting for us to be deceived."

Zixue questioned: "I don't think the gods are willing to come to such places."

Lu Yu said calmly: "Some things are not something you don't have to do if you don't want to. Gods are nothing in the upper realm. Some commands must be executed, so you dare not neglect your duties."

After hearing what Lu Yu said, the prince of the Black Prison did not dare to neglect, so he quickly took Lu Yu and Zixue around the Burning Soul Ridge, which took a full day.

“Have you found it?”

Zixue noticed Lu Yu's expression change and found that he was frowning.

“Not found yet.”

Lu Yu's answer stunned Zixue.

"Since you haven't noticed, why are you frowning?"

Lu Yu smiled and said, "I feel strange because I didn't find it."

The prince of the Black Prison urged: "Let's go in quickly, I want to rescue the master as soon as possible."

Lu Yu said seriously: "You can't go in, you can't bear the burning flames of the Soul Burning Ridge. Just wait for me outside. No matter what happens, you can't go in until I come out."

"But……"

The prince of the Black Prison was worried and wanted to follow him in.

"If you want to rescue your master, you must be obedient. This place is very strange. I can't bring you two to the first time in peace, so you all have to stay."

Zixue understood what Lu Yu meant and reminded him: "Be careful, we'll be waiting for you here."

Lu Yu looked at the Burning Soul Ridge and tidied up his clothes a little. This action was puzzling.

The next moment, Lu Yu stepped out, his whole body silently without any fluctuations in his breath.

Zixue and the Prince of Black Prison were both surprised. They clearly saw it, but they could not sense any fluctuations from Lu Yu.

If you close your eyes, you will definitely not be able to sense Lu Yu's existence by just relying on your spiritual sense.

Outside the Soul Burning Ridge, the five-colored flames twist the void.

Lu Yu was like an elongated oblique shadow, twisting and swinging during the progress, as if he was traveling through the cracks in time and space.

"Did you feel it?"

The prince of the Black Prison turned his head and looked at Zixue, and asked inexplicably.

Zixue's beautiful eyebrows frowned slightly, and an unprecedented solemn look appeared on her beautiful face.

"I felt that his breath was very strange, like walking through time and space, walking in the memories of the past, making it difficult to understand."

The prince of the Black Prison said in confusion: "How did he do this? I have been in and out of here countless times, and it is useless to try my best to do everything. Why did everything become so vulnerable when it comes to his hands?"

Zixue said: "This is where he is stronger than us."

The five-colored flames contain the power of destruction, which can devour the martial souls of cultivators and the spirits of rotten masters. Even Lu Yu felt a great threat.

After entering the Soul Burning Ridge, Lu Yu slowed down and the martial soul above his head appeared. The three-leaf green lotus was filled with the light of chaos, absorbing the colorful soul fire.

As the Holy Soul Heavenly Master, Lu Yu could see the general situation of the Soul Burning Ridge at a glance. The soul fire here can refine the souls and make the souls of cultivators below the Heavenly Martial Souls scatter and turn into dust.

In my memory, my old friend Ding Yunyi was just a earth-level martial soul, so why was he imprisoned for hundreds of years and not dead?

This is a big doubt. The prince of the Black Prison did not understand, but Lu Yu knew it.

“Is this a trap?”

Lu Yu's eyes were hot. Even if it was a trap, he would rescue his old friend because this was what he owed in his previous life. No matter what price he paid in this life, he would have to compensate him.

The mountain of Burning Soul Ridge is steep, and the soul fire here is terrifying. It is difficult for experts in the Divine Map realm to fly in the sky, so Lu Yu did not easily break through.

Moving along the mountain, Lu Yu carefully looked at the terrain of the Burning Soul Ridge, thinking about another issue in his mind.

Does the formation here have anything to do with the alchemy furnace I obtained before?

That alchemy furnace is extremely exquisite. It is an immortal furnace in the era of the Demon Immortals. It can refine immortal medicines. Lu Yu still needs to spend time studying it slowly.

It is important to save people now, but Lu Yu is moving very slowly because this place gives him a strange feeling, and there is a kind of power in the dark that is controlling him.

Lu Yu acted naturally and took an hour to climb over a mountain and saw the scenery deep in the Burning Soul Ridge.

There is a canyon between the three mountains. According to the story of the Prince of Black Prison, his master Ding Yunyi was trapped there.

Outside this canyon there are seven-color flames, which are made up of many divine signs, and lightning can be seen occasionally.

Lu Yu looked at the canyon and then moved his eyes to the three peaks.
