Lei Aotian walked for more than two hours, and had left the central area of the wreckage of the ancient battlefield, and there were fewer abandoned weapons scattered on the ground, and the number of skeleton soldiers encountered nearby had also decreased a lot.

But almost all of the skeleton soldiers on the periphery of the ancient battlefield were holding weapons in their hands, and a few were wearing scattered armor, and their movement speed was obviously much faster than the whiteboard skeleton soldiers they had encountered before.

These skeleton soldiers are no longer the original milky white bones, the color of their bones is mostly silver, and some skeleton soldiers still have some golden spots on their bodies, but the amount of golden spots is not as large as that on Lei Aotian's bones.

These evolved skeletons have also fought each other before, robbing each other of equipment, weapons, and soul fire to strengthen themselves.

Along the way, there are silver skeleton soldiers, who will turn their heads to look at the two knives in Lei Aotian's hand, one long and one short, and they seem to want to rob.

Fortunately, seeing that there were many faint golden spots in Lei Aotian's bones, most of the skeleton soldiers gave up the idea of robbery after a few glances and stayed away.

There are also some skeleton soldiers who don't have long eyes, and their tempers are relatively violent, and they rush directly towards Lei Aotian.

Lei Aotian has already gained experience in killing skeleton soldiers, and he uses two-sided three-knife moves, combined with tetanus skills, although the moves are simple, but they are quite powerful against a single skeleton soldier who doesn't understand the moves.

After shattering more than a dozen silver and golden-spotted skeleton soldiers, two silver-skeletal skeleton soldiers silently followed Lei Aotian about five meters behind him.

The weapons in the hands of these two silver skeletons pointed to the ground, and they had no intention of attacking Lei Aotian, and their big teeth collided up and down to make a "creaking" sound, grinning at Lei Aotian.

Lei Aotian didn't know if the two silver skeleton soldiers were talking babbling, or if they were just subconsciously moving their teeth.

"You go ahead!" Lei Aotian tried to point forward with a long knife and ordered the two skeleton soldiers.

These two skeleton soldiers are really obedient, and they are ahead of Lei Aotian.

After receiving the two skeleton soldiers, Lei Aotian continued to move forward.

Along the way, after more than a dozen battles, the number of skeleton soldiers under his command reached nine silver and one with golden spots.

Finally, eighteen hours after arriving in this undead realm, Lei Aotian saw a stone forest in front of him.

After finding a big rock, Lei Aotian climbed up and ordered his ten skeleton soldiers not to approach and stand around the big stone.

Lei Aotian lay on the big rock and fell asleep.

I didn't dare to sleep too deeply, and after sleeping for more than five hours, Lei Aotian woke up.

Lei Aotian began to take his little brother of the skeleton soldiers to hunt the skeleton soldiers.

Time passed day by day, and by the tenth day of coming to this undead world, the bones on Lei Aotian's body had turned golden, and he began to take thousands of skeleton soldiers to dig pits and kill the walking corpses of the new species of the undead world found nearby.

No matter how far away the walking corpse is, Lei Aotian didn't dare to go deeper.

On the fifteenth day, the skeleton soldiers found a bone dragon lying on the ground with injuries in a basin.

The bones of the bone dragon were as crystal clear, but one of the two wings was gone, and there were still many cracks and missing bones in the body.

There was also a big crack in the skull of the bone dragon, and the soul fire inside was like a torch, turning red and purple.

Lei Aotian looked at the obviously seriously injured crystal bone dragon, hesitated for a moment, and then gave an order, allowing thousands of skeleton soldiers to pounce on it and begin to besiege the disabled dragon.

The head of the bone dragon dragon spit out gray dragon breath, and the soul fire in the brains of the skeleton soldiers covered by the dragon's breath was instantly extinguished, and the rows of skeleton soldiers' bones disintegrated and turned into a pile of broken bones.

Fortunately, the bone dragon was also injured in the leg, and he couldn't move on the ground, so his attack range was limited.

The weapon in the skeleton soldier's hand hit the bone dragon crystal skeleton, clanging, but unfortunately there were only faint small scratches, and there was no substantial damage.

Lei Aotian took advantage of the chaos, went around to the back of the bone dragon, climbed on the back of the bone dragon with dozens of skeleton soldiers, and stabbed out the short knife in his left hand at the broken wound of the dragon's head, and launched the [Tetanus] skill.

After the fight, Lei Aotian immediately stepped back and jumped off the back of the bone dragon to stay away.

After being hit by the wound in the bone dragon's head, his body shook violently, throwing the skeleton soldier on his back and starting to spew dragon breath wildly.

Lei Aotian waited for more than ten seconds, and found that the [Tetanus] skill that killed the skeleton soldiers and walking corpses with one blow before couldn't kill the injured bone dragon, and only enlarged the bone crack that was already in the bone dragon's head.

There were still more than two thousand skeleton soldiers under his command, and since the fight had already begun, Lei Aotian decided to try to grind the Bone Dragon.

After waiting for the frequency of the bone dragon's breath to decrease, Lei Aotian touched the back of the bone dragon and launched a [tetanus] attack on the crack of the dragon's bone, and ran away after the fight.

Five times back and forth, there are only more than a hundred of the two thousand skeleton soldiers under his command, and the skull of this crystal bone dragon has not been shattered.

Lei Aotian had no choice but to give up.

The bone dragon had begun to notice his golden skeleton soldier, and prevented Lei Aotian from jumping on his back again.

Lei Aotian withdrew with the only remaining more than 100 skeleton soldiers under his command, but he couldn't defeat him!

If you continue to fight, you should be ground to death by this bone dragon.

Just after walking more than 200 meters, a large black shadow swooped down in the sky.

A demon with big black wings on its back descended and rushed directly to the ground as a crystal bone dragon.

A red flame sword appeared in the Great Demon's hand and slashed at the bone dragon.

The dragon head of the Crystal Bone Dragon lifted up and began to spit dragon breath.

A battle between the Great Demon and the Crystal Bone Dragon began, and Lei Aotian led more than a hundred skeleton soldiers under his command to speed up and run.

The space near the crystal bone dragon actually began to condense dark gray energy balls, and with the crystal bone dragon's low groan, these dark gray energy light balls quickly hit the big demon.

The Great Demon held the Flame Sword in both hands, the length of the Flame Sword doubled again, ignoring the attack of the dark gray energy ball, and the Flame Sword stabbed into the injured head of the bone dragon.

An explosion of energy sounded, and dust flew up.

Dozens of seconds later, the dust settled, the skull of the bone dragon shattered, the head of the crystal bone dragon was crooked, the dragon's head fell to the ground, and the soul energy in the skull like a torch was exposed, no longer protected by the crystal bone.

There were also several hollows on the Great Demon's body, bright red blood spurted out of these hollows, and there were also ruptured internal organs at the wounds, all of which had just been penetrated and injured by the dark gray energy light ball launched by the Crystal Bone Dragon.

Ignoring the injuries on his body, the Great Demon laughed wildly, stepped forward, and grabbed the soul flame in his brain.

The dragon head of the random bone dragon that had suddenly fallen to the ground instantly raised and bit the neck of the Great Demon.

The bone dragon's sharp teeth pierced directly into the flesh of the Great Demon's neck.

The Great Demon Hand howled in pain, and the Flame Sword immediately condensed from his hands, stabbing the bone dragon's body at once.

But the bone dragon had already bitten and didn't let go, and dozens of seconds later, the great demon actually chose to blow himself up.

At this time, Lei Aotian had already run out of a position thousands of meters away, found a dirt pit and depression, and after looking back at the battle situation behind him, he immediately jumped into the dirt pit and lay down.
