After confirming that Zhou Quankun left, Lin Mu finally put down the stone that had been tense in his heart.

Thanks to his wise choice to continue moving deep into the Demon Back Leader, otherwise he would not be able to get rid of Zhou Quankun's pursuit.

After Zhou Quankun left, Lin Mu continued to go deeper for a while in order to ensure the insurance, and stopped in a valley.

Lin Mu released his divine sense and found that the poison in the vital energy here had reached a certain level. He believed that if Zhou Quankun chased him here, even as a warrior in the Great God King realm, he would definitely not be able to resist the poisonous vital energy here.

After coming out of the safe area of ​​the Demon Back Collar, Lin Mu will always maintain the mysterious breathing method, because if he stops operating the mysterious breathing method, Lin Mu will not be able to resist the extreme poison in the vitality here.

"In fact, in addition to the extremely poison in the vital energy, the vital energy here is very rich. I wonder if my Dao Hong Furnace can refine the poisonous vital energy in the demon back tribe?"

A sudden flash of inspiration in Lin Mu's mind. He suddenly had a thought. I wonder if the vitality in the magic back leader can be used as a resource for his own cultivation?

Thinking of this, take action immediately.

"Big Road Honglu!"

Lin Mu shouted lightly and sacrificed the Great Dao Hongfu, then activated the Great Dao Hongfu to start absorbing the vitality between the world.

The poisonous energy in the Demon Back Glory was extremely poisonous. Even warriors in the Great God King Realm were extremely afraid. Lin Mu was not sure whether his great Dao Hong Fu could refine the poisonous energy in the Demon Back Glory.

However, Lin Mu's worries were soon proved to be redundant. When he activated the Great Dao Hong Fu and tried to refine the poisonous vital energy, he basically refined it without any effort. The efficiency of refining the poisonous vital energy is still very high!

What surprised Lin Mu the most was that the poisonous energy in the Demon Back Glory seemed to be very high. He only refined a part of the poisonous energy, and these poisonous energy were basically refined into equal amounts of original energy.

Generally speaking, when practicing, the amount of vital energy that is refined and converted into the original vital energy is about 10% or 20% of the vital energy that is converted.

In other words, the conversion rate of vital energy is about one tenth to two tenth.

In places with rich vital energy, the conversion rate will increase to 30% or 40%, which is between 30% and 40% of the year.

What surprised Lin Mu was that the conversion rate of vital energy here was almost 100%, or not 100%, and 97% or 8%.

Such a conversion rate of vitality can scare people if you say it out.

It just so happened that Lin Mu practiced the mysterious breathing method that can resist the poison in the vital energy in the demon's back leader, and his great road furnace can support him to continuously refine the vital energy. His dantian Qi sea is still extremely wide, and can accommodate a large amount of original vital energy after refining.

All these coincidences combined, for Lin Mu, it made a great adventure.

Lin Mu was secretly happy and began to urge the Great Dao Hong Furnace to refine the energy between the world.

As Lin Mu activated the Avenue Furnace with all his strength, the nearby poisonous energy suddenly surged towards him.

For Lin Mu now, these poisonous vital energy are treasures. As long as he continues to refine it, it can be converted into the original vital energy and filled into the dantian Qi sea.

In the next ten days, Lin Mu sat upright in this valley and urged the Great Dao Hongfu to refine the vital energy between the world.

Who would have thought that even warriors in the Great God King Realm feared the poisonous energy, at this time, became Lin Mu's valuable cultivation resource.

Ten days later, Lin Mu finally advanced to the early stage of the ninth level of the Heavenly Man Realm, and his strength soared a lot again.

After being promoted to the ninth level of the Heavenly Man Realm, Lin Mu did not stop practicing, and continued to absorb the poisonous energy between the surrounding heaven and earth, and continued to refine and practice frantically.

Immediately after Lin Mu found that he had been promoted to the ninth level of the Heavenly Man Realm, he continued to refine the poisonous energy here. He was no longer as effective as he was at the eighth level of the Heavenly Man Realm.

Half a month passed, and Lin Mu was promoted to the middle stage of the ninth level of the Heavenly Realm with the help of the vital energy between the surrounding heaven and earth.

Lin Mu found that the effect of continuing to refine the poisonous energy nearby was no longer very small, so he stopped refining the poisonous energy here.

If you stay here to refine the poisonous energy and want to advance to the tenth level of the Heavenly Man Realm, it will be at least a few months later, so Lin Mu does not plan to use the poisonous energy here to practice. He is going to see the environment here in the Demon Back Leader to see if there are any adventures like secret realms.

Logically speaking, this is the depth of the Demon Back Collar. If there is still a secret realm here, you will definitely gain a lot.

Lin Mu kept operating the mysterious breathing method because although he was promoted to the middle stage of the ninth level of the Heavenly Man Realm, the poisonous vital energy here is still poisonous to him. If he did not use the mysterious breathing method to resist, the vital energy here would melt into a pool of pus and blood.

Lin Mu walked out of this valley and found that there was still a vast primeval forest nearby.

The vegetation here is very special, not ordinary trees. The trees here have no leaves or branches, and all have blood-red trunks. This forest is a blood-red forest, which looks very strange.

Lin Mu released his divine sense, and his divine sense could only extend one kilometer in this forest.

Lin Mu did not notice anything abnormal in the range that Lin Mu could cover.

"It's strange. I've already penetrated into the Demon Back Corps. I haven't encountered any creature in the Demon Back Corps. When I was chased by Zhou Quankun last time, he mentioned that there were blood beasts or beast spirits here. Now I've already penetrated into the Demon Back Corps and I haven't encountered any creatures. Is this still the outer area of ​​the Demon Back Corps?"

Lin Mu guessed in his heart.

Lin Mu found that a blood-red tree not far away seemed a bit special. Compared with other trees, this tree looked very tall, at least twice as tall as the rest of the trunks. In this forest, it stood out.

Intuition told Lin Mu that this tree was a little different, so he walked towards the tree, intending to see what was special about this tree.

When Lin Mu was about to approach this giant tree, the tree suddenly shook violently and a strong blood burst out from its trunk.

"Where is the human boy who dares to invade my king's territory? Do you think you have lived long?"

A hoarse voice came from the towering tree.

Lin Mu was stunned. This tree could actually speak?

He looked closely and saw a portal on one side of the tree, and immediately guessed that there might be creatures living in the giant tree.

You can sense the blood and energy emitted by the other party that the opponent's strength is about between the eighth level of the God King Realm and the ninth level of the God King Realm.

boom!

The portal on the side of the giant tree suddenly opened, and a strange creature stepped out of it.

This strange creature has four heads, eight arms, eight legs, and blood-red bone spurs all over its body, looking very strange.

The strange creature stared at Lin Mu with blood-red eyes and said coldly: "Human boy, it seems that your cultivation is not very high. Why can you resist the blood poison in the vitality here when you go deeper here?"

The strange creature asked curiously.

After hearing the words of this strange creature, Lin Mu finally knew that the poison in the vitality in the Demon Back Glory turned out to be blood poison.

"The blood poison here is nothing to me. There are some things around here. Can you introduce it to me? I'm not very familiar with it when I first came to the Demon Back Collector."

Lin Mu said lightly.

"Oh? You still want to find out the news from me. You are quite brave. Which sect are you disciples? Come and report your name. I won't kill the nameless people."

The strange creature said in a commanding tone.

"You don't kill the nameless person? Are you so confident to kill me?"

Lin Mu smiled faintly.

"Hehe, you are a mere human warrior at the ninth level of the Heavenly Realm. It's easy to kill you. I'll give you another chance to report your name. I can consider freeing you a whole body."

The strange-shaped monster laughed.
