Neidan is a symbol of the power of the demon beast, with the inner dan, the demon beast has the possibility of advancement, and because of the inner dan, the physique of the demon beast is much stronger than that of humans.

But correspondingly, Neidan is also the Achilles heel of demon beasts, so they usually protect it carefully, and they will not use it easily unless they have to. You must know that damaging Neidan will lead to a great loss of spiritual energy and even death.

The giant python in front of him obviously lost his mind and actually destroyed Nedan himself. Although it can increase strength, it is only temporary, and once time passes, the consequences are unimaginable. However, this crisis and opportunity coexist, if the giant python uses the power of temporary improvement to defeat Duan Fei and hide from the spirit grass, then everything will be worth it.

Duan Fei's face was very serious, he didn't expect that with the help of Neidan, the momentum of this giant python was actually on par with himself at this moment. With a slight flick of his wrist, a long fiery red whip was held in Duan Fei's hand, and a whip flower was thrown out, and the aura on it was slightly rippling, and its power should not be underestimated.

"Chiming!" As soon as the red whip appeared, Jin Hu immediately recognized it.

When Bai Yi heard these two words, he looked at Bai Ling'er for some reason.

The girl understood and immediately explained to Bai Yi, "Chiming is Grandpa Duan's weapon, but it is made of the hair of the black gold silk and the fire lion, and the power can be increased a lot when you attack with it. But Grandpa Duan has never used it, and today is the first time I've seen it!"

"What's more!" Jin Hu added again, "This Chi Ming, because of the fire lion, can greatly enhance the fire attribute aura, for Duan Lao, that is a rare good thing!" In this tone, there was a strong sense of envy, and compared to it, his own nine-ring knife was a little shabby.

"Evil beast, I want to see what else you are capable of!" Holding Chi Ming in his hand, Duan Fei drank with confidence, waved his long whip, and threw it away at the giant python.

"Roar ......" The voice of the giant python changed with its body, and it let out a roar, and in the face of Duan Fei, who took the initiative to attack, he also rushed straight over, it seemed that he was obviously going to fight hard.

"Boom!"

The two collided, making a huge noise, which shook everyone's eardrums, and their feet were also trembling with the aftermath. Many demon beasts hiding in the mountains couldn't help but tremble when they heard such movements.

The dust stirred up by the battle slowly fell after a long time, and the figures of the giant python and Duan Fei appeared. The giant python's body, although protected by scales, was still marked by Chi Ming, which looked a little uncomfortable, but this trace disappeared in a few breaths. The recovery ability of this demon beast can be seen.

Seeing this, Duan Fei did not hesitate at all, and threw out another whip.

The cyan python was also not to be outdone, its body swung and dodged the attack, and a snake tail swept out, attacking Duan Fei's body directly. At the same time, he opened his bloody mouth, and the dense venom, with the sound of breaking through the air, shot out like a sharp needle.

With one blow into the air, Duan Fei hurriedly returned to defense, jumped backwards, dodged the snake tail, and the red Ming in his hand swung rapidly, quickly drawing a circle in front of him, and the red aura was immediately protected.

The "Ding Ding ......" liquid poison needle touched the red whip, emitting a series of crisp sounds, and then was twisted to pieces.

A few breaths, the two have been fighting for several rounds, but they are still evenly matched. Maybe because of the Spirit Transformation Grass, the two didn't make too drastic moves, otherwise if they accidentally destroyed it, it would be worth the loss.

Several defeats have made the giant python's eyes fierce, if this situation continues, I am afraid that I will die here today.

At this thought, the python let out a roar of rage, and its body temporarily paused. A faint cyan aura covered the surface of his body, and the scales on his body stood upside down at this moment.

Looking at the movements of the cyan python, Duan Fei understood that the former was ready to make a desperate gamble and make a last ditch effort.

This cyan aura is getting stronger and stronger, and the aura between the surrounding heaven and earth is surging towards the giant python at this moment. And looking at Duan Fei, it seems that he is also brewing some moves, absorbing the aura of heaven and earth at a speed that does not lose to the giant python.

The two aura, one green and one red, attracted the surrounding wind to surge within a few zhang.

After a long time of brewing, the aura on the surface of the giant python's body began to shrink, and on its wide open mouth, it was compressed into a huge cyan poisonous needle, which still shone with the slightest light.

"Whew!"

The sound of breaking the sky sounded, and the huge poisonous needle flashed out, and the energy on it was extremely violent, but it only took a breath to appear in front of Duan Fei.

And at this moment, Duan Fei was also ready, and the Chi Ming in his hand suddenly became extremely hard in an instant, looking like a red spear from a distance.

"Chiming Burst Flame!"

Duan Fei clasped Chi Ming with both hands, and his aura instantly surged, and a huge fireball burst out from the front end of Chi Ming, drawing a trace, and with an extremely terrifying momentum, it collided with the cyan poison needle.

Because the two of them controlled their strength extremely exquisitely, when the poison needle and the fireball clashed, they did not burst, but were tightly entangled and stuck in the air.

"Brother Golden Tiger, are you sure of this old man?" Feeling the extremely violent energy not far away, Bai Yi licked his lips that were a little dry from excitement, and asked in a hoarse and stiff voice. After all, this movement was a bit shocking to Bai Yi. As for Bai Ling'er, she was directly ignored.

"It's hard to say!" Jin Hu didn't dare to make a conclusion, if Duan Fei deliberately fought a protracted battle, victory would only be a matter of time, but this giant python obviously understood his disadvantage and wanted to decide the winner with one move, plus the demon beast's physique was already strong, so the victory or defeat was still two words.

Just as everyone was watching the battle between the two, no one noticed that Bai Ling'er tiptoed to the side of the Spirit Transformation Grass, and muttered in his mouth, "That stupid big snake, let's fight slowly with Grandpa Duan, and I'll quietly pick it up first." After saying that, he picked the spirit grass in one hand.

But what the girl didn't know was that the reason why the two controlled their strength was all because of the spirit grass, how could they not notice their small movements.

Just when the spirit grass was in the girl's hand, the giant python roared, and the huge cyan poison needle instantly turned into dense venom and rushed towards Duan Fei.

His body dodged downward, and a huge fireball whistled past the scales, exploding on the mountain not far away, causing a loud bang.

In the place where the giant python was bruised, the scales peeled off, and its internal organs were faintly visible, and blood was constantly spurting out around it. And the giant python endured the pain and rushed straight towards Bai Ling'er, it would never allow it, under its nose, someone took away the spirit grass.

"Not good!" Duan Fei hurriedly exclaimed, but in the face of the venom in the sky, he couldn't get out of his body for a while, and could only watch the giant python attack Bai Ling'er, and couldn't help but speed up his subordinates.

"Miss Ling'er!" Everyone also reacted in an instant, hurriedly picked up the weapons in their hands, and performed their own killing moves on the giant python, but unfortunately they only resisted for a moment, and they all collapsed.

The girl had never experienced anything at all, and when she saw the giant python attacking, she was so frightened that she stayed in place and didn't know what to do.

Just when the giant python was about to attack the girl, a figure flew out diagonally, blocking in front of Bai Ling'er, and the body of the giant python slammed into its body. And this figure was Bai Yi, when he saw the attack of the giant python, he didn't have time to think about it, so he instinctively pounced forward and protected Bai Ling'er with his body.

"Bang!"

Bai Yi flew upside down like a cannonball, and his strong force directly embedded it in the mountain, and then passed out, and the remnant jade on his chest also dimmed a lot.

"Whew!"

After Duan Fei cleaned up the venom, he saw Bai Yi being beaten out, and he was angry at the moment, and threw the red inscription in his hand out of the air.

A sound of breaking the sky sounded, the giant python didn't have time to dodge, its body was pierced by Chiming, and it was directly nailed to a giant tree, and then Duan Fei rushed to it, and slapped it with an angry palm. The giant python was already injured a lot, how could it withstand this palm, the snake's head was directly bombarded, and suddenly, blood and flesh were splashed.

"Brother Bai Yi!" At this time, Bai Ling'er reacted, shouted, dropped the spirit grass in his hand, and ran towards Bai Yi, whose life and death were unknown.
