The sound of metal grinding in the stone wall became louder and louder, and soon Yang Cheng felt that the cave seemed to be shaking again, and this earthquake-like feeling made him retreat to the deepest part of the cave, and he was watching ahead vigilantly.

Heavy footsteps "rumbled", and they were getting closer and closer to Yang Cheng.

Just as Yang Cheng was ready to attack, the stone wall in front of him suddenly collapsed, revealing a hole inside, and what appeared at the mouth of the hole was something similar to a robot.

"Robots? Were there robots in ancient times? Yang Cheng's common sense told him that the first robot on earth was invented by Engelberg, who enjoys the reputation of "the father of robots", in 1959, and the age of Long Xuzi is not known how many tens of thousands of years earlier than Engelberg.

The robot shook its head from side to side, probably looking at Yang Cheng who was standing in front of it, and then let out a not very coherent word from its mouth: "Intruder...... Damn it! ”

Yang Cheng then understood, it turned out that this robot was the guardian of this cave, he thought about it, the small piece of dragon pattern black gold in this cave, maybe the stone box in his hand was the most valuable, in other words, this robot has been made to protect this stone box!

"To protect this stone box? Long Xuzi's predecessors are really a lot of money! Yang Cheng put the stone box into the storage ring, and at the same time held the wolf's tooth war knife in his hand.

The robot doesn't have much autonomous consciousness, and when it was created, it was only infused with one thought by Long Xuzi, that is, to protect the stone box from being seized by outsiders, so when it saw Yang Cheng put the stone box away, the aura on its body suddenly skyrocketed, and its strength was close to the Great Perfection of the Qi Gathering Realm!

"Qi Gathering Realm Great Perfection?!" Yang Cheng was shocked, if he hadn't broken through the Qi Gathering Realm a few days ago, it was very likely that he would have been defeated by a robot here!

The robot had no thoughts, no emotions, and rushed towards Yang Cheng, and its fists wrapped in ice attribute spiritual power continued to wave in front of it, although the action seemed simple, the destructive power contained in the fists was estimated to be able to catch up with the "Picking Leaves and Flying Flowers" performed by Yang Cheng in the middle of the Qi Gathering Realm!

Yang Cheng's feet stepped on the wind step, and his body dodged to one side, and at the same time, the wolf tooth war knife in his hand stabbed into the robot's body!

Seeing the firelight splashing, his wolf tooth war knife only scratched a white knife mark on the shell of the robot, and the robot's fighting intent did not decrease, and he turned around and smashed the iron fist down towards Yang Cheng again!

"Bang bang bang-"

The iron fist kept smashing on the ground, and the broken stones were flying everywhere, but fortunately, Yang Cheng dodged in time and was not hit by the iron fist, otherwise it would have become a puddle of flesh.

"It's really difficult! There is no sense, there is no pain, once the killing order is activated, it will fight to the end, I don't know if the predecessor of Long Xuzi designed such a guardian to test future generations, or really want to put future generations to death? ”

Yang Cheng put away the wolf tooth battle knife, and the movement of the "Demon Wolf Nine Style" was unleashed between his hands: "Since the physical attack can't hurt you, then it's always okay to destroy you with overwhelming destructive power!" ”

"Demon wolf howling!"

Yang Cheng roared, behind him, a white demon wolf was also roaring angrily, with his movements, the white demon wolf jumped high and pounced towards the robot, at the same time, the sound waves from its mouth roared continuously on the robot's body, making a piercing sound.

Yang Cheng's body regressed, and a move "Demon Wolf Transformation" was unleashed, and the white demon wolf suddenly opened its blood-red eyes, two fierce lights flowed out of its pupils, and the breath of killing instantly descended on the entire cave!

"Demon Wolf Transformation" is the last style in the "Demon Wolf Nine Styles", and it is precisely the use of the Demon Wolf's complete ferocity to achieve the strength that surpasses the Demon Wolf itself!

"Sky Wolf Slash!"

The killing qi condensed on Yang Cheng's arm, and a blood-red war knife phantom appeared from his hand, and when the robot and the demon wolf were fighting, the blood-red war knife slashed down!

"Boom-"

Only the sound of rubble splashing could be heard in the cave, and the heavy dust was scattered, choking Yang Cheng to cover his mouth and nose and want to run out, but just as he wanted to take a step, he vaguely saw a huge hand waving in the dust, grabbing his ankle tightly, and firmly fixing him in place!

"Haven't you been ruined yet?!" Yang Cheng was surprised.

However, before his words fell, the giant hand holding his ankle suddenly let go, Yang Cheng waved his arm, and the spiritual power swept out, pushing away all the choking dust, only to see that the robot had been split into pieces by the "Heavenly Wolf Slash" that condensed the killing aura, and the arm that was shocked by the air wave just landed at Yang Cheng's feet, so the scene just now appeared.

"If you die, you will be a monster! Senior Long Xuzi, you really deliberately embarrassed the juniors! Yang Cheng said to himself.

Yang Cheng exhaled deeply, sat down on the robot's arm, and then took out the stone box from the storage ring, held his breath and slowly opened it!

A cold air hit him, but after experiencing those things just now, Yang Cheng had already taken precautions against this, so that the cold air did not invade his body, so that he saved a lot of unnecessary trouble.

The cold air dissipated, and he saw a piece of jade slip lying quietly in the stone box, and he was about to reach out to take out the jade slip, when he heard Ye Yanbing's voice from the cave.

"Master, are you in there? What just happened? How did it look like an earthquake?! ”

Ye Yanbing and Fei Nan heard the vibration sound coming from the cave, and they were really relieved, so they both climbed up from under the cliff and rushed along the lighted road in the cave.

Seeing Yang Cheng sitting on the body of a robot couldn't help but surprise Ye Yanbing and Fei Nan.

"Master, you are ......"

Yang Cheng looked at the jade slip in the stone box, and was very excited, because he remembered that the sacrificial spirit had said that the exercises that could be recorded with the jade slip were all above the yellow grade, such as "Xuanyin Alchemy Technique" and "Xuanyang Alchemy Technique" were only passed down orally by the sacrificial spirit, and it was at Yang Cheng's request that the sacrificial spirit engraved these two exercises on the jade slip.

"Yan Bing, I have found a special exercise for you for the teacher!" Yang Cheng shook the stone box in his hand to Ye Yanbing.

"Give me exercises?" Ye Yanbing was both surprised and a little happy, surprised by the mess in the cave, and delighted that Yang Cheng actually helped her find the exercises!
