Yi Xing just saw Su Su injured and vomiting blood, lying on the ground, and he was so angry that he inadvertently used a move on the fifth chapter of the Sword Sutra, which forced Yu Kui Xing back in an instant, and then scratched the other party's cheek. At present, seeing that the other party is using a Xuanyin stick to protect his body, he is pressing up step by step, and he doesn't know how to start for a while.

In desperation, he could only resist with a long sword and retreat step by step. Fortunately, Yu Kui Xing was injured by Yi Xing twice in a row, even if this injury was insignificant at all, with Yu Kui Xing's vigilance in the countless dangers he had experienced in the past, he had to protect his own safety first if he did not seek to hurt the enemy quickly. This allowed Yi Xing to retreat calmly, otherwise with Yi Xing's strength, Yu Kui Xing's full attack would be defeated in a moment.

Yi Xing saw that the other party was so cautious, and he felt a little relieved. Although he didn't understand why the other party had changed his previous fierce posture, this situation was already the best for him.

The study space was always limited, and he had to avoid the medical fairy who was healing, and Yi Xing was soon forced into a corner. Seeing that there was no way to retreat, Yi Xing couldn't help but be anxious, and sweat flowed down his cheeks to the placket of his clothes......

Seeing that Yi Xing had no way out, Yu Kui Xing waved the Xuanyin stick and smashed it towards Yi Xing. This stick is ferocious, and if it touches it, it will either kill or be injured.

Yi Xing gritted his teeth, urged his true qi, and tried to avoid the space shrouded by the Xuanyin Stick, stabbing diagonally into Yu Kui Xing's chest from bottom to top. He had no way to do this, according to the speed of his sword, even if he could stab the other party, with the ability of the other party, he could also hit him hard when he used up this move. Fighting with a powerhouse of this realm for so long has far exceeded the load of Yi Xing, at this time his state is already extremely poor, his dantian true qi and aura are almost exhausted, although there are no wounds on his body, under the attack of the other party, he is also exhausted.

This move was already the best way he could think of to hurt the other party. Yu Kui Xing couldn't have imagined that at such a time, Yi Xing would actually use such a trick that was almost equivalent to the same end, Yu Kui Xing was already winning, where was he willing to fight with him for this kind of dangerous move, in case of a careless, there might be an accident.

I saw Yu Kui Xing, glanced at Yi Xing, decisively withdrew the stick, and easily used the Xuanyin stick to block Yi Xing's dangerous move, and Yi Xing's plan was completely frustrated. Although because the other party retreated, he got out of the danger just now. He clearly understands that this is just a wave of offensive losses from the opponent, and soon the opponent will hit the second and third waves...... His face was full of bitterness, and he still didn't have enough strength after all!

"Ah......h

Yi Xing was stunned by the scene in front of him! He saw that Su Su suddenly rushed out from the side at the moment when Yu Kui Xing retreated to defend against his move, and when Yu Kui Xing's mind was all about dealing with Yi Xing, he sneaked in. With one stroke, he stabbed the sword on Yu Kui's back, and the blood dripped on the floor of the study, and the red was extremely dazzling......

It turned out that Su Su was shocked when he saw Yu Kui Xing forcing Yi Xing into a desperate situation, and he couldn't care about his injuries in a hurry, so he swung his sword and was about to come up to rescue Yi Xing. Unexpectedly, Yi Xing wanted to fight with each other at this critical moment, and he scared Su Su's legs weak. Fortunately, Yu Kui Walker retreated at the last moment, which also gave Su Su, who rushed behind Yu Kui Walker, a chance to sneak attack.

If it was in another environment, even if Su Su wanted to sneak attack, he couldn't, but Yu Kui Xing was a top powerhouse after all, although he had taken Yi Xing seriously, but deep down he still didn't regard him as an important threat, and after seeing through Yi Xing's move, the feeling of playing with the other party made him feel a kind of fluttering. All this gave Su Su a chance, and this is why such an unbelievable result occurred.

Su Su was seriously injured before and did not reply, and in just a few breaths, his life was always hanging by a thread, and his heart kept shaking, and after he stabbed Yu Kui Xing with his sword, he was already unsupported, and he fell down before he could walk to Yi Xing's side.

Seeing the bloodstains on Su Su's clothes, Yi Xing's heart was extremely painful. Quickly hugged Su Su, who was about to fall to the ground, and felt Su Su's pulse, which was okay! No big problem! I felt that Su Su was fine, but he was tired and physically exhausted, and Yi Xing was very happy in his heart.

"Ahh

"You ant-like human race will sneak up on you and deceive people, all the disgusting methods. Next time, I will definitely take your dog's life!" Yu Kui Xing shouted angrily, and the wound on his back was pulled by the angry drink, and more blood flowed out. The ground was bright red. One turned around and walked away.

Yi Xing hurriedly picked up Su Su and came to the medical immortals Qian Yichu and Xu Gongzi, who had already walked over here.

"Senior, your injuries are healed?" Yi Xing asked when he saw that the other party looked as usual. Just now, the Yu Kui walker didn't make any more moves, but he saw the medical immortal Qian Yichu coming over. Yu Kui Xing was severely injured by Su Su, and in this case, his continued entanglement was tantamount to taking chestnuts in the fire, and the gains outweighed the losses, so he left decisively.

"I didn't expect that one day I would be rescued by three teenagers!

"Your name is Yi Xing, he's your sister, you're all very good! And this little friend, Xu Gongzi!

The medical fairy took Su Su and looked at it, took out a slender needle, and pierced Su Su's hands and feet in a few places. "This little girl is restless, if she doesn't let her sleep peacefully, I'm afraid that it will leave hidden dangers in the future! Now put her in bed to rest and wait for her to wake up!"

Yi Xing was shocked when he heard that Su Su's heart was hurt, but fortunately, when the medicine immortal said the end, his face was soothed.

The medicine fairy saw the change in Yi Xing's expression in his eyes: "The relationship between your brother and sister is extraordinary!"

"Don't dare to hide your predecessors! It's like this......" Yi Xing told how the two met and how they depended on each other all the way. Of course, how did I get the "Meridian Theory" written by the old man in Tsing Yi as a gift to the medical immortal...... It's all told as it is.

"The world is unpredictable! hahaha!" After hearing this, the medical fairy sighed with emotion. I didn't expect this young man to have such a relationship with him.

The more they looked at Yi Xing, the more they liked it. Finally, the medical immortal spoke up and asked the three of them to come here in the future, and he taught them the essence of the meridian theory. Because when he was probing Su Su's injury, he had already found that Su Su still had many deficiencies in the meridians, and then he probed Yi Xing and the others, but he didn't expect that the two were even worse than Su Su, so he moved his mind to teach the essence of the meridian theory of the three people.

The Theory of the Meridians was written when he was still young, and his later practice and experience have pushed the theory and application of the meridians to a new peak. Now he likes the three of them from the bottom of his heart, and he can't help but impart knowledge. How could Yi Xing and the others not know the meaning of this, and immediately agreed happily.
