The formation aura that emerged on the trunk of the Fusang tree was connected with the aura that formed the mountains, and instantly burst out with huge power. From top to bottom, it roared on the corpse of the three-legged golden crow wrapped in the roots of the tree.

Obviously, when the witch clan realized that the three-legged golden crow's corpse wanted to escape, he was completely cruel. He would rather destroy it completely than let the demon clan take it away.

"Bang." The spiritual light went down the trunk, about 80% burst out from the main root, directly bombarding the three-legged golden crow's corpse, and 20% spread along other roots.

A huge roar exploded underground, shaking the earth. The body of the three-legged golden crow, which was already struggling, was instantly bombarded and fell into the depths of the ground, and many of the golden feathers on their bodies flew out.

In addition, the stones and soil within a radius of five or six thousand meters were instantly smashed into powder by the spiritual light spreading from the roots, and the entire ground collapsed again, which was more than 200 meters deep.

Chen Feng is within this range, of course he cannot be immune to the impact. Fortunately, he has layers of protection from the Wuji Yin and Yang Ball, but he was not shocked to death on the spot.

However, when the huge impact force hit him, the violent shock force still made his qi and blood churn, and a bloody smell appeared in his mouth and nose.

When Chen Feng tried his best to encourage his true energy to fight against the constantly coming formation aura and shock waves, he also released the sword threads and kept wandering around, rolling the feathers of the three-legged golden crows flying around.

These feathers are of the best refining materials regardless of their length, so Chen Feng naturally would not let them go.

In fact, even if it has escaped from the three-legged golden crow's corpse, these feathers are still covered with a layer of blazing sun true fire, that is, Chen Feng's sword thread is extraordinary. It is covered with sun true fire, so it can withstand the burning of sun true fire on these feathers. Otherwise, it would be really delusional to sweep it away.

When the golden light flashed, feathers flew to Chen Feng under the guidance of the sword thread. He quickly pinched the magic tricks, knocked down the ban, temporarily sealing the true sun fire on the feathers, and then put it in the storage bag.

Chen Feng's movements were as fast as lightning, and he completed this series of movements in a short while. Seeing that most of the feathers had been taken away by him, he no longer wanted to take away other feathers. After all, he still understood the truth that too much was too much.

As soon as he stepped on the ground with his right foot, a rumbling sound rang out, and his body had already fallen downwards.

Before, he had been trying his best to fight against the shocking power suppressed from above, and also resisted the impact of the formation aura just now. The ground within a hundred meters around him was intact.

However, the ground under his feet had already been taken out by the sword threads, and it fell into it just now. It slid down more than a thousand meters deep in an instant, and then turned into a horizontal tunnel.

Chen Feng's previous idea was to help the three-legged golden crow's corpse overturn the Fusang tree, then destroy the eye of the formation, and then break the formation out. However, although his idea was good, he found that the situation changed faster than he expected.

In fact, this is not surprising. After all, the witch clan has been operating here for at least two or three thousand years. How could it be possible to leave too obvious loopholes for people to get into?

Now that the previous idea is not working, Chen Feng immediately used the backup plan.

Although the formation here is powerful, because the earth veins are gone underground, the range that the formation aura can extend is greatly reduced, and Chen Feng decided to use this to escape from the predicament.

The sword thread dug down more than a thousand meters deep, and it was already far away from the farthest range that the formation aura could reach. Even the powerful shocking power suppressed him a lot, Chen Feng was equivalent to coming to a relatively safe area.

However, Chen Feng did not relax because he knew that the fierce battle above was still going on, and being deep in the ground might not be safe, so he did not stop at all. He could always use the sword silk, the sun's true fire, and the Wuji Yin and Yang ball to dig and burn, and continuously extend the tunnel to the distance.

Chen Feng knew in his heart that he would be really safe only by completely leaving the core area of ​​this formation. As for treasure hunting, he would not consider it at all. This time he was quite satisfied to be able to catch some of the roots of Fusang trees and the feathers of the three-legged golden crows.

People should not be too greedy, and this is especially true when the benefits are present, otherwise people will really have to be deprived of their hearts and swallow the elephant.

Chen Feng was not moving slowly underground, at least faster than ordinary people running, but he was still a little dissatisfied and couldn't help thinking: When will you find a secret method such as earth escape?

With the Wuji Yin and Yang Ball in hand, he will use secret techniques such as earth escape to achieve twice the result with half the effort, and it is very useful whether it is fighting or running away.

As Chen Feng walked forward, he could also hear loud bangs and loud bangs coming from the tunnels, and the earth was trembling. He could imagine how fierce the battle above was.

"I don't know if this battle will win or the demon clan will win?" Chen Feng thought randomly, and suddenly his heart pounded wildly, and a strong alarm suddenly came.

"Bang." At this moment, a big hole suddenly broke on the wall of the hole around him, and then a huge mouth full of sharp teeth appeared and swallowed it towards him.

"I'll go, there are actually earthworms that escape the net." Chen Feng's thoughts flashed, and the yellow light around him suddenly expanded, and it directly hit the giant mouth that was already close to him like a huge fist.

"Boom." This yellowish light was the earth-type spiritual energy burst out from the Wuji Yin and Yang Ball. It was extremely heavy. When it hit out, it seemed like a mountain smashing out. It immediately shattered the mouths of the earthworms and the teeth of the mouth full of their mouths. The dark green juice splashed everywhere, corroding the surrounding stones, but it did not hurt Chen Feng, who had Wuji Yin and Yang Ball protecting the body.

This luckily escaped the ground lung earthworm that had driven away by the demon clan had originally felt the rich blood emitted by Chen Feng and wanted to hunt for food, but unexpectedly, he encountered a tough guy. Although the severe pain made it extremely angry, it also made it feel the fear of death.

Without thinking, the earthworms of the ground lung retreated into the hole they had just dug, and it seemed that they wanted to escape.

But how could Chen Feng let it do what it wished? With a wave of his right hand, he had already pinched a series of magic tricks. The next moment, the Wuji Yin and Yang Ball flew out and hit the broken mouth of the earthworm in the ground lung with a bang again.

The earthworm in the ground lung screamed and shook faster, but Chen Feng chased after him with his sword, and beating him with a bang bang behind him.

The earthworm of the ground lung is not only huge in size and strong in vitality, but will not die easily even if it is cut into two parts. It also has a peculiar feature that it has mouths at both ends of the front and back, which means that it can drill holes when it is underground, and it is even more unpredictable when attacking the enemy. Because when you disrupt one head and think it will die, another head may also appear and swallow you in one mouthful.

Chen Feng had fought with the earthworm before, so he naturally knew this. Of course, he would always be on guard against the counterattack of the other end of the earthworm's mouth.

However, as far as the ground lung earthworms are concerned, they don’t care about these things at all. Because they are so painful that they are beaten by Chen Feng, they are only able to escape in a panic.

In this way, Chen Feng was like finding an authentic tunnel excavator who was not expensive, just driving it forward from time to time, and moving underground was more than ten times faster than before.

Of course, Chen Feng would not allow the earthworms to run around aimlessly, but instead headed towards the direction away from the combat area. Therefore, Chen Feng would occasionally use the Wuji Yin and Yang balls to bombard the earthworms with the earthworms, just like driving animals, letting it drill forward in the direction it wanted.

Although the earth lung earthworms drilled very fast underground, they could not swallow stones and soil endlessly. There were always times of fatigue. But before it wanted to stop, Chen Feng would give it a few hard times, forcing the earth lung earthworms to run away again.

It was not until the earthworms in the ground lungs were overwhelmed by excessive consumption of stones and soil and were forced to die. Chen Feng had to stop.

After the earthworm died, Chen Feng also gained some vitality of life, but not much, only about five or six thousand, which was a bit too little compared to its huge body.

Chen Feng was not surprised by this, because he noticed this when he killed the earth-lung earthworms in the underground secret passage.

In fact, not only the earthworms in the ground lungs, but also the demon birds and monsters here do not emit much vitality after their death, which makes Chen Feng feel very strange.

However, Chen Feng did not dislike it, especially in order to fight against the shocking suppression of the powerful force, he consumed a lot of life energy, almost 70% to 80% of his previous accumulation, and now only 40,000 to 50,000. It is naturally good to be able to supplement some of it now.

Chen Feng looked at the corpse of the earthworm in the ground lung, and after hesitating for a moment, he released a sword thread to divide it.

On the earth, earthworms are a Chinese medicine, and Chen Feng also wanted to see if the earth lung earthworms can be used as medicine.

The earthworm's body is quite huge, and Chen Feng cannot take it away completely. He can only choose some parts that look pretty good and cut them down and put them in the storage bag.

In addition, Chen Feng also found three or four earth-yellow demon pills in the body of the earthly earthworm. Although the quality is average and there are a lot of impurities mixed in it, it contains a very rich essence of Wu Earth.

Chen Feng immediately threw it into the Wuji Yin and Yang Ball. Soon the demon pills were ground by the Wuji Yin and Yang Ball, and the impurities and demonic energy were all eliminated, and the remaining essence was integrated into the Wuji Yin and Yang Ball. This also made the quality of the Wuji Yin and Yang Ball slightly improve.

"If I had known this, I would have searched for its corpse after killing the earth lung worm." Chen Feng thought with regret, and then activated the sword thread to dig upwards.

After digging upwards for seven or eight hundred meters, he broke out of the ground, but he saw endless darkness.

"I'll go, where is this?" He looked around and couldn't tell the difference between the south, west and north. At the same time, he smelled a pungent fishy smell coming with the wind.
