Cao Xudao took out a quaint scroll, on which thunder could be faintly seen, and both sides each dripped a drop of essence blood on the scroll, and made a contract.

Yuan Ming felt a strange power lurking in his body, he knew that this was the power of the contract, once he violated the contract, the power of the contract would release thunder light to strangle him.

"Pick up!" Yuan Ming's gaze suddenly flashed like a silver snake, extremely fierce, and without waiting for Cao Xudao to make a move, he quickly took a few steps and stepped forward.

Seeing Yuan Ming, who was already approaching him, Cao Xudao did not panic at all, and with a slash of his right arm, a vicious wind was struck.

Yuan Ming knew that the comer was not good, but he did not dodge, he wanted to test Cao Xudao's strength. The same punch was blasted out, the momentum was terrifying, and the space continued to resound with a sonic boom.

"Gather the word body!" Yuan Ming drank lightly in his heart, his right arm twisted strangely, and then collided with Cao Xudao's right fist.

"Bang!" A surging wave of qi spread from the junction of the two fists, and the surrounding trees and boulders were swept away, and the two of them remained immovable with such great force.

But in fact, Cao Xudao had already suffered a dark loss, and his fist was fierce when he collided, but Yuan Ming used the Juzi body, and most of his strength was absorbed by Yuan Ming, as if hitting cotton, and the qi and blood in his body surged.

Cao Xudao snorted, his eyes glanced at Yuan Ming deeply, his right foot paused, and he spun to Yuan Ming's left side with his strength, and his fists quickly struck, and he had already punched out more than a dozen punches in a short time.

Yuan Ming was naturally not afraid, his body took a few steps back like a swimming fish, and directly avoided Cao Xudao's bombardment. When Cao Xudao was stunned when he saw him dodging, the whole person rushed forward, and the force gathered before was released together with the twisting of the muscles.

"Ha!" Cao Xudao chuckled, his originally stunned figure instantly became dexterous, and several afterimages slipped out of the air, easily avoiding Yuan Ming's cohesive attack.

"Bang!" Yuan Ming punched the ground, and suddenly the sand and stones flew, and the ground cracked into a turtle pattern. Yuan Ming was also surprised, he didn't expect Cao Xudao's movements to be so agile, and he wasted the strength he had gathered.

"Huh!" Cao Xudao's surprised voice came, you must know that the land in this area is extremely hard, it is the unique tungsten earth of the Wukuang Mountain Range, if he does not use all his strength, he will not be able to leave a crack on it, and the fifteen-year-old Yuan Ming can actually do it to the point of cracking the tungsten earth. It's amazing!

Cao Xudao's figure floated forward a few steps, and took it out with a palm, although he did not use spiritual power, but the body that has been nourished by spiritual power for a long time is very strong, if this blow hits the body of an ordinary person in the spirit core realm, I am afraid that it will directly become meat mud.

Yuan Ming's body retreated, and he also saw that the blow that Cao Xudao seized the opportunity to use was extremely powerful, and if he was accidentally hit, he would be seriously injured if he didn't die.

Now he can only use his right arm to fight him, after all, his right arm is mutated, and the hardness and flexibility are almost several times that of other parts of his body, but he didn't dare to hold it up, and his right arm collided with Cao Xudao's palm.

"Drink!" Yuan Ming felt that there was an endless dark energy coming from Cao Xudao's palm, and he couldn't bear it even if he wrapped around his mutated right arm, Yuan Ming knew that this was Cao Xudao's fighting technique, that is, martial arts.

"Bang!" Cao Xudao's right leg was pulled out unreasonably, Yuan Ming's waist was hit at once, and the whole person flew out, his body was still too weak, and his waist without mutation and reinforcement could not withstand Cao Xudao's blow.

If it wasn't for the physical problem, otherwise he would be invincible in countless ways!Yuan Ming thought in his heart.

"You're good, I can see a trace of your martial arts in this short fight, but your physical body is too weak, and even the ordinary physical body of the Spirit Core Realm is not as good. You must know that the foundation of martial arts is the physical body, and if the physical body is not strong, the road of martial arts will not go very far!" Cao Xudao said with a hint of a smile on the corner of his mouth: "This is a body refining technique of my Cao family, and a bottle of first-layer cultivation beast blood, I hope that the next time I see you, you can take my ordinary blow with your physical body, and then let me see your martial arts!"

Cao Xudao took out a bamboo book and a crystal white porcelain vase and handed it to Yuan Ming, and then walked away without looking back.

Yuan Ming was stunned for a long time, why did someone always give him the body refining technique, could it be that his physical body was so bad?

He smiled wryly and opened the bamboo book, on which were written the words "Vajra Body". Yuan Ming then slowly looked at the entire bamboo book, and then looked up to the sky and pondered.

The first layer of the vajra body is the iron rigid body, which needs to eat the essence blood of the spirit beast with the golden spiritual power of iron characteristics, Cao Xudao gave him the essence blood of the famous iron horned rhinoceros in the middle and periphery, and he hoped that Yuan Ming could enter the first layer and strengthen the physical body.

Yuan Ming didn't know what his true intentions were, but how could he not want the good things that others gave him.

However, he was not prepared to cultivate the Vajra Body, because the Immortal Food Technique was far more powerful than it, and it could be seen that the first layer of the Blood Melting Realm did not limit the number of blood melts.

Yuan Ming picked up the porcelain vase and opened his eyes to watch, he didn't know if Cao Xudao could be trusted, if the blood of this iron-horned rhinoceros was poisonous, wouldn't he die here?

He was very annoyed in his heart, he also knew that his body was weak and he urgently needed to enhance the strength of **, this bottle of iron horned rhinoceros blood was placed in front of him, but Yuan Ming couldn't move, it was really distressing.

"Ming, this bottle of beast blood is not poisonous. Yu Ya'er glanced at the beast blood and said delicately.

"How do you know?" Yuan Ming was surprised.

"My eyes can see through a lot of things. Yu Ya'er pointed to her eyes with her cute little white paws.

Yuan Ming smiled slightly, then stared at her double pupils and said, "The red pupils are actually split into two!" Yuan Ming suddenly noticed that there was a horizontal crack in the middle of Yu Ya'er's red pupils.

"Hmm. Yu Ya'er nodded the fox head, shyly avoided Yuan Ming's gaze, and whispered: "Sister said that once the pupils are united, a powerful chaotic force will erupt!"

"Chaos power?" Yuan Ming frowned slightly, and some relevant knowledge appeared in his mind and said, "The Red Pupil Spirit Fox does have the Chaos Spiritual Power mastered, but I have never heard that the Red Pupil Spirit Fox's split pupils can be combined into one. ”

Yu Ya'er shook her head and said, "I don't know very well, these are all what my sister told me." ”

"Hmm. Yuan Ming answered, and then opened the porcelain bottle and prepared to refine his body.

He believed in Yu Ya'er's ability, and he also felt that Cao Xudao would not harm him, if he wanted to kill himself, he could kill himself by virtue of his physical advantage before, which was not a violation of the contract, so he felt that Cao Xudao was still credible.

Drinking all the iron horn rhino blood in the porcelain bottle into his stomach in one gulp, Yuan Ming immediately felt a blazing flame ignite in his dantian, Yuan Ming hurriedly ran the mantra of the first layer of the Secret Food Formula, if he hesitated any longer, I am afraid that he would be burst.

With the Secret Food Formula, the flames in the body filled the whole body, and the meridians of the whole body burned together, and a pain no less than corrosive pain instantly filled Yuan Ming's entire mind.
