The bronze blood dragon root is rooted in the second layer of the Sinmin Cave, constantly absorbing the power of bronze ore and receiving the nourishment of the bronze-level Sinmin Aura. After thousands of years, a bronze blood has been condensed.

It can be said that that bronze blood is the essence of the bronze blood dragon root, and the power it contains is at least 70% of the entire bronze blood dragon root.

The power was very violent, like a volcano erupting, one after another, continuously impacting all limbs and bones.

After personal experience, Chu Mu realized why Long Yunkong said that he had to neutralize other spiritual medicines to be refined. This violent power was simply not something that ordinary practitioners could bear. Even a normal level five holy body could not withstand it. At least, a level six holy body could bear it.

Fortunately, although Chu Mu is a level five holy body, he has the healing ability close to level seven holy body, so he barely supports it.

Next is the difficult step, refining.

It is undoubtedly a lot of energy to refine the violent power.

The Shenhuang Sword Yuan cut away a trace of violent power. Through repeated transports, it gradually refined it into the Shenhuang Sword Yuan. The powerful Shenhuang Sword Yuan was only invisible.

Concentrate, ignore everything outside, and control the Shenhuang Sword Yuan to continuously refine it.

This power is very violent, like a wild horse that is untouched, and Chu Mu must have enough patience and perseverance and strength to subdue it, but his body must continue to bear the repeated impacts of the violent force.

Fortunately, refining violent power can weaken it little by little, which is equivalent to weakening the damage it causes to the body.

The body of Zi Jian was even weaker under the secret technique of igniting spirits. His power level has also decreased a little, and he is at the level that barely reaches the intermediate level of the Nine Star Saint Level, and may fall to the primary level of the Nine Star Saint Level at any time.

In this case, the old man, Monkey King, never used powerful sword skills. Instead, he was patient to consume the power of the purple sword, because using powerful sword skills meant that his own power would also consume more. He wanted to kill Chu Mu, and no other accidents were allowed.

At this time, he felt that the aura around Chu Mu on the altar was increasing little by little, but he didn't take it seriously, because the amplitude of the enhancement was not obvious. Secondly, he felt that a four-star holy level, no matter how much it was enhanced, he was not an opponent of a nine-star holy level.

However, the one-eyed old man would still pay attention to Chu Mu's movements. Once Chu Mu left the altar, he would immediately explode, get rid of the purple sword and kill Chu Mu.

Kill Chu Mu. He doesn't need to get entangled with the Purple Sword anymore and can leave directly.

Refining Refining Refining!

A trace of violent power was tamed and turned into the Divine Wilderness Sword Yuan, causing the Divine Wilderness Sword Yuan to increase little by little. From the early stage of the Fourth Eternal Heaven, it gradually approached the middle stage.

A quarter of an hour later, Chu Mu's cultivation level finally made a small breakthrough. He reached the middle stage, and at the same time, the power level of the purple sword also dropped to the initial level of the Nine Star Saint level.

However, his swordsmanship was still very strong, allowing him to continue fighting with the one-minded old man.

After his cultivation level broke through to the middle stage of the fourth level of the Eternal Heaven, Chu Mu's refining force suddenly increased a little, and the damage to his holy body by the violent force was also appropriately reduced, not so obvious, but Chu Mu's self-healing ability did not decrease.

Refining speed is further improved.

This time, in just half a quarter of an hour, Chu Mu's cultivation level was able to break through from the middle stage and reach the late stage.

After reaching the late stage, the refining speed increased a lot again, and soon reached its peak.

The difference between the peak of the fourth level of the Age and the early stage of the fourth level of the Age is still very obvious.

"If you improve, you will have to die." The old man, the Zi Jian sneered secretly. At this time, the strength of the Zi Jian was further weakened and was completely suppressed by the old man, the old man, who was looking for an opportunity to give the Zi Jian a fatal blow.

The blood-colored sword light filled the air, and the strange, sharp and tricky attacks from all angles made the purple sword overwhelmed, but the sword was used to barely support it.

Zi Jian also realized that Chu Mu was improving his strength and was at a critical moment, so he tried his best to hold the one-eyed old man.

From the peak of the fourth level of the Age of the Eternal Heaven to the early stage of the fifth level of the Eternal Heaven, it is a change in the great realm, and its difficulty in improving is even higher.

If you want to make a breakthrough in your daily life, it will take at least several years of accumulation to have hope. But at this moment, there is sufficient supply of power. To make a breakthrough, it will only take a short time. However, at this moment, every minute and every second seem very urgent.

Refining Refining Refining!

Shock Shock Shock!

The peak of the fourth level of the eternal heaven... the limit of the fourth level of the eternal heaven!

Breakthrough is just a line of separation.

"Are you breaking through your cultivation?"

“Is it useful?”

"Even if it is a breakthrough, facing the one-eyed old man, there is only one way to die."

Some people also discovered that Chu Mu's aura was increasing, and they immediately understood that this was a breakthrough and immediately discussed.

"How did he do it? In a short period of time, he was promoted from the early stage of the fourth level of the Age of the Age of the Fourth Level of the Age of the Age of the Age of the Age of the Extreme."

"I must have taken some kind of magic medicine with powerful effects, I saw it."

Refining, constantly refining, and accumulating strength.

The violent power became weaker and weaker, and the impact on Chu Mu's holy body could no longer cause any damage.

"Okay, let's make a breakthrough in one go!"

The power accumulated enough, Chu Mu worked hard to mobilize all his strength and impact the bottleneck.

At the same time, the one-eyed old man used a terrifying sword technique, and the blood-colored sword swung out and turned into a blood-colored aurora. It was incredibly fast, so fast that it was impossible to catch the sight, and it ran across the sky and shot towards the purple sword.

The speed was too fast, the purple sword was directly hit and flew backwards, and the blood-colored light flowed on his body, further weakening his aura, and his power dropped directly to the level of barely the initial level of the Nine Star Saint level.

The purple sword is not a human, but a kind of spiritual body. When the spirit body that exists in the sword sect’s spiritual seal is attacked, it will not be injured or killed like a human. Instead, its strength will decline and will only disappear when it drops to a certain level.

"Die!" The old man with one-eyed eyes said coldly and murderous intent, and he set out his sword again.

Swish swish swish swish!

Blood-colored aurora burst into the air and rushed to the sky, trying to shoot the purple sword from all directions and angles.

Zi Jian reacted quickly, holding the hilt of the sword with both hands, and his strength fluctuated. The purple-gold flame on his body became fierce in an instant, as if adding fuel to the fire, and his breath also surged a lot.

"The Emperor's Way is Wuji!" A loud shout was like the emperor's wrath, floating corpses thousands of miles away.

The great sword burst out with an extremely strong purple-gold light, sweeping across the world.

The sound of shattering sounds continued to sound, and blood-colored aurora hit the purple-gold light, shattering one after another, turning into light spots and spreading, extremely beautiful, but this beauty carries a fatal crisis.

"Blood Killing Soul-Scouting Sword!" The old man, who was one-eyed, was a little surprised that he immediately burst out with a stronger sword technique.

An extremely strong blood-colored light gushed out from the body. Behind it, it seemed as if a huge unjust soul roared, captivating the soul.

A sword passed through the sky, and the blood-colored sword light turned into an unjust soul and rushed towards the purple sword quickly.

Blood Killing Soul-Scrawling Sword!

Ten thousand meters apart, everyone saw the blood-colored wronged soul, and their faces suddenly changed. They only felt their soul trembling, and an indescribable terror emerged from the depths of their souls.

The purple sword's pupils reflected the blood color and immediately turned into purple gold.

"Reign of the world!"

With one sword, the extremely rich purple-gold light, like a diamond, shining the vacuum and descending to the earth.

Collision, terrifying fluctuations fluctuate, impacting all directions, and the ground shattered.

The purple and golden sword light was shattered by the blood-colored sword light, and a little left of the blood-colored sword light was shot towards the purple sword, shattered after the purple sword's big sword.

"It's still so difficult." The face of the one-eyed old man looked a little ugly. Seeing that the opponent's strength was declining, he exploded in one fell swoop, using powerful sword techniques to attack and kill, trying to defeat and kill him in one fell swoop.

Unexpectedly, the other party was so tenacious and mastered such powerful swordsmanship. Even if his power was not as strong as his own, he could still fight against him.

"The Emperor's Wrath!" Zi Jian turned his defense and attacked and took the initiative.

Behind it, there seemed to be a phantom of the emperor, the ministers rebelled and the emperor was angry. In an instant, everyone from ten thousand meters away felt that they were in trouble.

The great sword was raised, and a huge purple-gold sword shadow appeared in the sky, condensed as if it were solid.

The giant sword fell, as if the emperor's judgment after being angry, made the old man Monkey King look solemn. This sword made him feel threatened.

"Blood Killing Purgatory Sword!"

Blood-colored light filled the sky, falling from the sky, as if hell had come, covering hundreds of meters in a radius, covering the purple sword.

The purple-gold giant sword seemed to cut off the heaven and earth, slashing in purgatory, and roars everywhere and vital energy fluctuated.

Evenly matched!

Everyone can see that the sword technique used by the Purple Sword is even stronger, and the difference lies in the absolute power of both sides.

With one move, Zi Jian's body faded a little again, his strength became unstable, and he was between the peak of the eight-star holy level and the initial level of the nine-star holy level.

Although the power of the one-eyed old man also consumed some of his strength, his own strength was a real nine-star holy level mid-level, without using any secret technique to increase.

One goes up and the other goes down, and the purple sword falls at a disadvantage again.

"Blood Killing the Wind Sword!"

With a sword swing, the sharp blood-colored sword light seemed to break through the sky, and it was incredibly fast.

A sword followed by a sword, and the sword was as if it was killed. The purple sword moved its footsteps, moved its body, and waved its sword to resist, but was still hit by a blood-killing sword. It was trembling all over. The hit part seemed to evaporate by high temperature, and disappeared directly, and other parts flowed, replenishing it.

At this time, Chu Mu's body trembled in the altar, and a powerful force surged in his body. The powerful aura instantly burst out, as if a volcano erupted, soaring into the sky.

The cultivation level finally broke through, from the peak of the fourth level of the eternal heaven to the early stage of the fifth level of the eternal heaven.

The violent power of the bronze blood dragon root has not been refined. There is still a part of the most violent power left and cannot be refined. (To be continued, please search for Astronomy, the novel is better, updated and faster!
