Yun Yang stroked the cold metal box in his hand. For some reason, he felt that he was connected by blood. Then, he felt that the blood in his body began to stir, as if it was rushing out of his body.
Without any hesitation, he bit his finger and dripped a drop of blood on the metal box. He wanted to see what was inside.
The drop of blood, like a piece of iron that was attracted by a magnet, actually stuck to it. Immediately after that, the metal box seemed to have a vein on it, sucking all the blood. Then, a ripple spread out from it.

"Buzz buzz!"
The box in his hand trembled violently and almost fell out of his hand. Yun Yang was shocked and hurriedly grabbed it with both hands.
"Ssssssssssssss
A small hole gradually appeared in the box. A golden light burst out from it, directly swallowing Yun Yang's body.
There was a dazzling golden glow all around, so it was impossible to distinguish the east, south, north, and west. Yun Yang did not have the time to observe carefully before he was sucked into the vortex-like rich energy and energy.
"Chi chi chi!"

The energy and spiritual essence were like sharp knives that cut through the surface of Yun Yang's body. The intense pain rushed over like a tide, squeezing his body crazily. The inexplicable pressure made his whole body tremble violently, and his eyes showed an incredible light.
"What on earth is this thing inside? It actually has such a powerful energy fluctuation!"
Yun Yang clenched his teeth and endured the impact. The surrounding energy fluctuation seemed to have turned into a whirlpool that could devour heaven and earth. The powerful suction force seemed to be absorbing all the blood in Yun Yang's body!
He panicked for a moment. Even in the face of the clouds, he had never felt such pressure!

"Puff!"
Under the impact of the strong energy, he couldn't help but spit out a mouthful of blood. His eyes were bloodshot. Although he was in a precarious situation, he still persisted.
Yun Xiao stood in the pavilion, his sharp eyes looking at Yun Yang through the golden light. He looked a little reluctant. "Yang'er, since you are not strong enough, don't force yourself. It's yours after all. It's not too late to take it when you are strong enough!"
Yun Yang's will had been blurred, but when he heard the sound of the clouds, he was shocked.
"Damn it, how can I let him look down on me!" Yun Yang was furious and his muscles were trembling. He only felt an incredible power surging out of his body, pulling him back from the edge of the cliff.
Yun Yang frantically grabbed the edge of the box with both hands and forcefully opened it little by little.
The more Yunxiao thought that he couldn't do it, the more he must do it!
She had to tell him that even if he didn't exist these years, she and her mother could still live a good life!
"Squeak squeak squeak!"
The gap in the box became bigger and bigger, and the golden light became more and more intense. Yun Yang clenched his teeth in anger. With a low roar full of anger, the box also opened.
"Whoosh whoosh whoosh!"
All the golden light disappeared. Yun Yang's legs were so weak that he almost fell to the ground, but he managed to hold on. His robe was in tatters and his whole body was covered in blood. There was a hint of unwillingness to admit defeat in his bright eyes, and he stared stubbornly at the metal box in his hand.
The box had been turned into ashes by the wind. At this moment, there was only a drop of golden blood in his hand that gave off a sweet fragrance. The golden blood seemed to be connected to his own blood. The sense of familiarity from the bottom of his heart would not lie.
Yun Xiao took a few steps forward excitedly and shouted, "Yang'er, you succeeded! Quickly, take it!"
In fact, Yun Yang did not need Yunxiao's reminder at all. With his instinct, Yun Yang had already sent it into his mouth without hesitation.
As the golden blood entered his body, Yun Yang only felt that his whole body was surrounded by a strong aura of energy, and his whole body was in extreme pain as if his tendons and bones were broken. As time went by, he suddenly found that the blood in his body had surged to the limit!
A huge amount of vital qi poured into his body. The qi and blood in his body were surging, like a raging tide, and the waves were roaring. The momentum around Yun Yang was huge, and the tens of thousands of pores on his body became red.
"Puff!"
With a slight sound, Yun Yang spat out a very tiny line of blood from one of his pores. Then, countless pores on the surface of his body spurted out tiny blood, and his whole person became a bloody man!
At this time, he could no longer feel the pain. He could only vaguely feel that his body was becoming stronger at a fast speed, as if he had been reborn.
Yun Yun's expression was pleasantly surprised. He did not even shift his eyes as he muttered in his mouth, "I am finally able to return the thing that I have saved for you fifteen years ago to you today!"
Yun Yang felt comfortable all over. His original blood was improving at a very obvious speed. In his body, the drop of golden blood constantly created new blood and replenished his whole body. And the blood in his body was spat out through his pores in this way.
The blood that was created was golden and shiny. The golden blood was obviously much stronger and more active than the original blood. Every time there was a little more new blood, Yun Yang would feel that his physical body was stronger and his strength was stronger. The feeling of becoming stronger from a weak person was too obvious, as if he was climbing up step by step.
In this way, he actually completed the process of changing blood!
