The scorching energy drilled into Lin Mu's blood and into his bones.

For ordinary martial artists, this feeling is absolutely painful.

But Lin Mu had been quenched by a different fire, and the relics were quenched with blood, and this pain was still within the scope of tolerance for him.

His mind was not disturbed much, but he was extremely happy.

The more violent the medicine, the stronger the effect, which is exactly what he wants.

Cultivation, continuous improvement.

Lin Mu's body is also getting stronger.

One, two, ten......

Finally, when Lin Mu swallowed a hundred Red Blood Feather Pills, the true qi in his body was completely boiling.

The bottleneck of the sixth order of the martial artist was broken through in an instant.

Seventh-Order Martial Master!

"Go on."

Cultivating a divine soul, and the will is extremely strong, it can be said that before the Martial Sect, Lin Mu didn't have to worry about the situation that his state of mind couldn't keep up with the martial arts realm.

As long as he has enough energy, he can continue to break through.

Whoa!

The waterfall outside flows day and night.

Inside the stone cave, an increasingly powerful aura is brewing.

In the blink of an eye, a day passes.

This Qingxu Cave Mansion also ushered in darkness.

The light of the Qingxu Cave Mansion came from a fake sun in the sky, but it was actually a huge energy crystal.

That spar should also be the energy core of this Qingxu Cave Mansion.

However, the energy contained in that spar was too terrifying, and Lin Mu didn't dare to pay attention to it.

He had used his divine soul to sense it before, and when he was hundreds of miles away, he felt thousands of degrees of heat, and if he got any closer, he would probably be burned to death and melted.

Therefore, he still honestly took the Red Blood Feather Pill.

The Red Blood Feather Pill in front of him decreased one by one.

By the end of the night, there were only 200 left.

Almost by dawn, fifty more disappeared.

If an outsider sees this scene, they will be stunned and distressed.

The Red Blood Feather Pill is worth tens of thousands of spirit stones each.

For example, the Red Blood Feather Pill refined by Lin Mu with the Immortal Refining Gourd has a Dan pattern, which is even more expensive, at least worth one hundred thousand spirit stones.

This is equivalent to Lin Mu consuming more than 30 million spirit stones in just one day.

At this time, Lin Mu didn't know the true value of the Red Blood Feather Pill, and if he knew, he would probably be in pain as well.

But even if it hurts, he can only last.

Cultivation already consumes a lot of resources, let alone him.

The foundation is dozens of times stronger than that of ordinary martial artists, and the resources consumed are also dozens of times larger.

Under the accumulation of this large amount of Red Blood Feather Pill, Lin Mu also got a huge harvest.

At dawn, his cultivation broke through again.

Eighth-Order Martial Artist.

"Shock Ninth Order Martial Master."

Lin Mu was full of ambition and wanted to directly attack the ninth-order martial artist in one go.

It's a pity that the further you go in cultivation, the more difficult it is to break through.

By noon, the remaining one hundred and fifty Red Blood Feather Pills had all disappeared, and Lin Mu had barely reached the peak of the Eighth Order Martial Artist.

"Although I haven't been promoted to a ninth-order martial artist, my cultivation has sprinted from the sixth-order peak to the eighth-order peak, which is not bad."

Lin Mu quickly adjusted his mentality.

Now, in this Qingxu Cave Mansion, the gap between his cultivation and that of the other hidden forces Tianjiao has become smaller and smaller.

It took another half an hour to completely stabilize his emotions, and Lin Mu opened his eyes.

Next, for him, is the real highlight.

"Little Bodhi fruit."

Four crystal-clear fruits of different colors are neatly placed in front of him.

These four fruits are the small Bodhi fruits that contain the mysteries of gold, wood, water and earth.

"I don't know, you're really as wonderful as the legend says."

Lin Mu stared at them.

Originally, he didn't have much hope for the cultivation of the Eight Desolation Sword.

To comprehend the mysteries of the seven systems, the ghost knows that it will be until the Year of the Monkey and the month of the Monkey, and maybe in this life, he will not be able to truly cultivate this sword technique successfully.

But now, in this Qingxu Cave Mansion, there is a little Bodhi fruit, a strange fruit that can help people comprehend the mysteries, which brings him hope.

"Whew."

With a long breath, he no longer hesitated, picked up the golden little Bodhi fruit, and ate it in one bite.

As soon as he entered his mouth, the little bodhi fruit disappeared and turned into an air current.

It was as if what he had eaten was not a fruit, but a bubble.

Almost at the same time, a drunken feeling enveloped his mind.

"This ...... This little Bodhi fruit has such a strong impact on the soul. ”

Lin Mu felt dizzy, his whole soul seemed to float, and his consciousness became more and more hazy.

After a moment, his mind seemed to enter a wonderful world.

It's a world where there are no other elements, only pure metal.

His soul became a tiny particle in the Infinite Gold Element.

The world of metal particles is not as harmonious as imagined.

Here, too, it's brutal.

All the metal particles are devouring each other, fusing together.

If it is not strong enough, it will be swallowed and fused by other metal particles.

The most powerful weapons in this world are some weapons, which are made by the fusion of countless tiny metal particles.

"You can only survive by devouring other metal particles."

Lin Mu naturally didn't want to be devoured, so he began to devour other metal particles.

At first, it was going well, but in the back, the metal particles he encountered became stronger and stronger, and the stalemate became longer and longer.

Seeing that Lin Mu was about to sink forever like this, a faint domineering aura came out from the depths of his soul.

This breath comes from his Northern Secret Technique.

On the path of devouring, the Northern Secret has the most powerful effect.

Airplanes!

Lin Mu's consciousness also showed a trace of clarity.

"I'm not Lin Mu, I'm not a metal particle."

Suddenly, in the depths of Lin Mu's soul, there was a lingering palpitation.

This little Bodhi fruit is really terrifying.

At this time, he had already realized that devouring the little Bodhi fruit was life-threatening.

If it weren't for the fact that he possessed the Northern Secret Technique, he would really treat himself as a metal particle and sink forever.

Until one day, he will encounter metal particles stronger than him, and then devour his consciousness.

Once that's the case, he'll really perish.

"I'm still a little careless."

The disciples of the Xuanbing Sect must have known about the danger of devouring the Little Bodhi Fruit, but they didn't tell him, they were obviously digging a pit for him.

"Calculations are everywhere, and the methods of these hidden force disciples are far from being comparable to those ordinary family disciples I met before."

"With this lesson, we must be careful and careful in the future."

As soon as he woke up for a while, the medicinal effects of the little Bodhi fruit soon came again, dragging him into that state of intoxication and haze.

Lin Mu did not resist.

It is only in this state that he can comprehend the essence of the mysteries of metal.

However, there was a trace of clarity left in his heart, so that he was no longer completely ignorant, but consciously devoured other metal particles.

When encountering powerful metal particles, he deliberately avoided them, devouring those who were weaker than him.

When he's strong enough, go devour the stronger ones.
