In the valley, after some searching.

The scattered Bingzhou Heavy Cavalry had already lightened the thick black mist that permeated the place a lot, and the Demon Devouring Stone continued to devour the demonic energy, making the field of vision farther away.

Du Yun originally wanted to take this opportunity to deal with Lin Zihan, whose soul had been corrupted by demonic energy, and it could be regarded as letting the other party get rid as soon as possible, but as a result, there was no one here.

Standing at the entrance of the underground base in front of the mountain wall, looking at the manually closed gate in front of him, Du Yun muttered to himself: "Maybe after the rebellion of the mutant beasts happened, the soldiers in the valley have already retreated." ”

"Lord, do you need to break open this door?" On the side, Zhao Yun asked.

"Well, break it open and see!"

Du Yun nodded.

Bang!

Bang! Bang!

After seeing the lord's consent, Zhao Yun, who was riding on the white tiger, shook the bright silver spear in his hand and stabbed violently, and after the grandmaster-level strength burst out, it suddenly slammed into the alloy gate.

With a dull loud noise, the alloy gate instantly split apart and exploded around.

The mountain also trembled violently.

Squeak squeak......

But at this moment, a mutant rat suddenly appeared in a crack in the mountain not far away, made a strange cry, and then suddenly turned around and disappeared into the crack.

Well? Why is it a mutant rat again?

Du Yun had already seen a mutant rat appear when the firebird and the flying mutant beast were fighting before, and when he saw it again at this moment, his brows suddenly furrowed.

This made him vaguely feel that something was wrong!

Sure enough.

The mutant beast had just disappeared, and before Zhao Yun, who had blasted open the door of the underground base, could enter it, he felt a violent aura coming out of it.

"Lord, be careful!"

At the same time, without even thinking about it, he brandished the spear in his hand and stabbed it.

"Whew!"

With an earth-shattering roar, a huge figure flew out of the demonic aura shrouded underground passage like lightning, and slammed straight into the spear that Zhao Yun stabbed.

Bang!

A tail flicked out and slammed into the spear at the front of the spear.

A huge force burst out, Zhao Yun was caught off guard and the spear in his hand sank down, and his body involuntarily took a few steps forward.

And in this short moment, the huge figure that rushed out had already leaped over, releasing a violent aura and rushing forward to Du Yun, who was riding on a horse.

Hum! Sure enough, there was a problem!

Because of the protection of the dragon heart jade, Du Yun was not affected by the violent aura, and he could see through the appearance of the monster in the black mist at a glance.

This is a mutated python with the initial strength of the grandmaster who has been infected by demonic energy.

As if it had been targeted, the mutant python flew out of the underground passage and did not fight Zhao Yun, but ran directly towards Du Yun.

As it opened its huge mouth and roared, a huge devouring force was suddenly generated.

Even the eight hundred Xiandeng Dead Soldiers led by Koji Yi in the back were faintly trembling under the influence of this devouring force, but in the end, they still resisted the suction and quickly dispersed.

"Gun and shield array ready!"

Swish! Swish! Swish!

Under Koji Yi's low roar, the Xiandeng Dead Man instantly surrounded this place in a semicircle, and the heavy shield in his left hand suddenly smashed to the ground, and the big gun in his right hand pointed straight forward.

As long as the python rushes over, they will not hesitate to stab their spears at each other!

In the end, there were even a hundred first-ascending dead soldiers who automatically formed a crossbow shield array.

Du Yun didn't have time to pay attention to the changes in the first dead man behind him, he looked at the giant python rushing over and opened his mouth to swallow himself, a cold glint flashed in his eyes, and he instantly took the mount back to the system warehouse.

At the same time, the purple gold armor also emerged and enveloped the whole body.

"Conspiracy? Hmph, it's just the right time for you brute to try the trick I just learned! Du Yun muttered to himself, and his body suddenly got rid of his devouring power and disappeared in place.

By the time he reappeared, he was already under the mutant python.

Looking at the abdomen of the giant python that was close at hand, Du Yun, who was releasing a grandmaster-level aura all over his body, urged the Yuan Force in his body to gather his right hand, and immediately waved it out after activating the drop of golden dragon blood in it.

"Dragonclaw!"

Poof!

With the splash of blood, the python's abdomen was as fragile as tofu, and it was torn open five times in an instant.

Then, as Du Yun moved forward quickly, the sharp dragon claws he left in the giant python's body directly turned into the most terrifying weapon, piercing the opponent's entire abdomen.

Blood is pouring out like rain!

Woohoo!

The sharp pain from the abdomen after it was thrown away made the giant python's body twitch for a while, and it suddenly let out a terrible scream, waving its tail to kill Du Yun below.

But unfortunately, Du Yun, who was agile, easily dodged the attack.

The power of the dragon's claws satisfied him.

Looking at the mutated python in front of him that was hit hard by himself in an instant, Du Yun didn't stop doing anything, flew up and landed on the other party's back, and Yuan Li gathered his feet to directly absorb it.

At the same time, his right hand, which turned into a dragon claw, plunged into the giant python's body again, and began to operate the dragon blood refining technique.

For a while, the blood in the giant python's body flowed uncontrollably under the traction of a strange force, and all of it converged under Du Yun's dragon claws.

And for a giant python, it's like being skinned with cramps.

Even if it was a mutant beast with the initial strength of the grandmaster, it couldn't withstand such a severe pain at all, and it flew everywhere completely crazy, crashing into the mountain with a deafening sound.

Over time, though, the crashes and roars became quieter.

Finally.

When Du Yun used the dragon blood refining method to refine all the blood in the python's body, leaving only a trace of golden blood into the dragon's claws, the python that fell to the ground and kept twitching and rolling completely lost its vitality.

Feeling the new trace of golden blood in his hand, Du Yun's eyes couldn't help but flash a touch of disappointment, and said: "After all, it can't compare to the cold Jiao in the cold pool, so it can be refined!" ”

"Forget it, it's better to have than nothing!"

Glancing back at the changes around the valley, he didn't think much about it, and waved his hand to condense a ball of fire that ignited the python and reduced it to ashes.

The demonic qi that rushed out at the end was also absorbed by the Demon Swallowing Stone!

"Lord!"

"Lord!"

……

Du Yun had just dealt with the giant python, not to mention keeping up with the first dead soldiers who were guarding the surroundings, and Lu Bu, Zhao Yun and Liyi walked over quickly.

The mount was temporarily set aside by them.

"How? Have you found out the situation? Du Yun looked at Lu Bu and asked.

When he was fighting with the giant python just now, Zhao Yun and Koji Yi were worried about his comfort, so they didn't pay attention to other things and kept waiting by the side.

But Lu Bu took the opportunity to check the surrounding situation.

Hearing Du Yun's inquiry at this moment, he suddenly nodded and said, "The lord guessed right, those mutant rats did not appear by chance, they were spying on us!" ”

"Outside this valley, a large number of demonized mutant beasts have begun to appear!"

Woohoo!

Roar!

……

As soon as Lu Bu said this, with a burst of roars, mutant beasts appeared in the mountains and forests on both sides of the originally calm valley, and their scarlet eyes flashed with bloodthirsty red light in the pale black demonic aura.
