The blood evil spirit is usually a place of battle, after hundreds of millions of soldiers were killed and injured.

A kind of evil aura condensed from the blood of the soldiers who died in battle combined with evil aura.

Generally speaking, ordinary blood evil energy only has no benefits to the human body.

Under the erosion of the blood evil energy, ordinary monks had no way to resist.

However... in this advanced ancient battlefield, the blood evil aura that scattered after these killed beasts died was another blood evil... This blood evil is a kind of evil aura that is condensed from blood under the erosion of the chaotic aura and extremely yin evil aura of the ferocious beast.

This evil energy is a special evil energy formed by the bloodline absorbing extremely Yin evil energy and being tempered by the chaotic airflow.

Once the ferocious beast is killed, this evil spirit will scatter.

If no one absorbs it, then these evil spirits will dissipate between heaven and earth under the devouring and erosion of the chaotic energy and the extremely yin evil spirits.

Once a monk is nearby and absorbs this blood evil into his body.

These blood evil spirits will quickly merge into the bloodline.

After being integrated into the blood vessels, these blood evil spirits can temper meridians, muscles, bones, and even blood vessels... Simply put, these blood evil spirits have the effect of strengthening the battle body.

As long as the blood evil is constantly absorbed, the battle body will be constantly tempered and strengthened... The warriors of the Manniu Clan also practice in this way.

Seize the blood evil energy of ferocious beasts and even soul beasts to temper your body. This is the method of body refining exclusively to the advanced ancient battlefield... This is also the reason why the Earth Mother God strongly recommends Chu Xingyun to the advanced ancient battlefield.

Simple, direct, and effective... As long as you slaughter a large number of these ferocious beasts and soul beasts and absorb a large amount of blood evil energy, you can quickly temper the battle body.

It is worth mentioning that... this blood evil energy must be absorbed and condensed on the spot.

Once the blood evil energy dissipates, within three breaths, it will be swallowed by the chaotic airflow and eroded by the extremely Yin evil energy.

Therefore...if you cannot absorb the blood evil energy within the three breaths.

Then this battle will basically be in vain... The way to refine the body is simple and difficult... In this advanced ancient battlefield, as long as the battle body continues to be slaughtered, the battle body will become stronger and stronger.

However... the quality of the blood evil energy that needs to be absorbed in different stages of body refining is also different.

Chu Xingyun, his current combat body can be said to be weak, just like a three-year-old child.

Therefore, even if a hen was slaughtered, the blood evil energy that was scattered was enough to greatly strengthen his combat body.

For Niu Li, with her combat body level, even if she hunts the manta, the income she gets is very small and almost negligible! Of course... this blood evil spirit is effective after all.

The effect will not be completely lost due to the improvement of the combat body level.

However, as the level of the battle body increases, the low-quality blood evil energy will be less and worse.

Once the level of the battle body is too high, the efficiency will be too poor when killing weak beasts.

Even if you kill millions of weak beasts, you will get the improvement.

I'm afraid it's better to kill a high-level, powerful beast and get more profits.

Whoosh... With a sound of breaking through the air, Chu Xingyun bent his bow and arrow, and a rune arrow roared at the green wild wolf... With a light sound, the wooden arrow accurately shot the green wild wolf.

But it is obvious that the wooden arrows, coupled with the penetration power of the short bow, cannot penetrate the fur of the wild wolf at all.

With the sound of a slight click, the wooden arrow fell to the ground like a toy.

Facing this scene, the four calves immediately grew their mouths blankly.

What is this? The toys they usually play with are more powerful than this one! Huh... Just when the four calves were stunned.

Amid a howling sound, a bunch of gray smoke rose up instantly.

In just a moment, the gray smoke completely enveloped the wild wolf.

Aww... Under the gray smoke, the gray wild wolf suddenly let out a painful wail.

The next moment... the blue wild wolf rushed out of the gray smoke frantically and rushed towards Chu Xingyun's position.

He saw it clearly just now, it was Chu Xingyun who attacked him.

Therefore, at this moment, the green wild wolf recognized Chu Xingyun and was determined to take revenge! Looking at the wild wolf that was grinning and rushing towards him fiercely... the four calves immediately became serious.

Although they were not afraid of these wild wolves, they would never dare to be careless when they really fought.

On the battlefield, any monk who develops the habit of being careless will soon fall.

Although the wild wolf's claws are difficult to break through the defense of the Barbarian Bull tribe.

But you should know that there is no creature that is qualified to survive on the advanced ancient battlefield, it is simple.

Although the destructive power of this blue wolf is perhaps really limited.

But his teeth are absolutely sharp.

He really bites it, let alone the leather of the Manniu tribe.

Even their strong bones can be bitten by wild wolves! The prey that died in the mouth of green wolves has always been corpses.

Not only will the flesh be eaten up, but the bones will be bitten and chewed into the stomach.

Even...even the blood on the ground would be licked by the green wolf, and even the hairs would not be left behind.

Therefore, as the green wolf broke through the gray smoke, the four calves became serious at the same time and prepared for the battle.

Once the green wolf approaches, they will surely launch a bull collision as soon as possible and knock the wild wolf away.

But soon... the four calves found that something was wrong! Before today, they had faced these blue wild wolves countless times with their mother.

Therefore, they are extremely familiar with these green wolves.

According to their memory and understanding... these green wolves are as fast as the wind and move as fast as lightning.

A distance of 100 meters can be crossed in as little as three breaths! But looking at the green wolf in front of him, his condition is completely wrong! Looking around, the green wolf was covered with black smoke, and his speed is extremely slow... If you want to cross this hundred meters, let alone three breaths, you may not be able to do it if you give him thirty breaths! This... under the gaze of the four calves... Although the green wolf looked fierce and grinned... in the end, he fell to a place about thirty meters away from Chu Xingyun and his group.

Finally... As the green wolf fell down, a blood-red wolf shadow roared out of the green wolf's corpse.

At this moment... the green wolf seemed to have lost consciousness! Driven by obsession, he still persistently launched a charge towards Chu Xingyun.

After losing the constraints of his body, the green wolf finally recovered its speed.
