Over the years, the great doctor has made painstaking efforts to prepare all kinds of poisons, and his martial arts are also five poisons. With these unorthodox means, the great doctor has killed many experts. In the battle, the great doctor constantly gropes for ways to prepare all kinds of poisons according to the strength of the martial arts, and even uses some martial arts to do experiments, inject venom, and observe the reaction of the martial arts, Then targeted improvement.

A powerful expert has powerful internal power and strong control over his body. He can use his internal power to resist poison. In order to make a stronger poison, the doctor always wants to find a powerful expert to do experiments, and Su Yang is the best choice. In the doctor's opinion, Su Yang's appearance is just a gift from heaven.

After pouring Zhuyeqing, the doctor presses his hand on Su Yang's wrist and observes Su Yang's physical reaction through his pulse. Su Yang is very cooperative and does not dissolve Zhuyeqing, leaving the venom rampant in his body.

A minute later, the doctor frowned slightly, looked at Su Yang's face and trembled, muttered: "Magu powder has a good effect, it has paralyzed the meridians, but the effect of Zhuyeqing is a little worse, so we should improve the formula." With that, the doctor took out a book and began to take notes seriously, just like students taking notes.

After finishing the recording, the doctor took out a red bottle. As soon as the lid was opened, a red smell came out of the bottle mouth, and then quickly dissipated in the air. Standing in the distance, Niu LAN and Hou Wen felt a hot breath. Yes, it was a hot breath, just like a flame flashed in front of them, but it was different, But they can't tell the difference.

After Su Yang felt the breath, it suddenly lit up in front of his eyes. It was the best fire poison, which was refined by the fire of five elements. It was also a good thing in the world of cultivation. Unexpectedly, the divine doctor had fire poison. It was the top-level strange poison, but the level of the divine doctor was limited. The prepared fire poison was very rough, and its power was very low, but it was just refined with Su Yang.

If the fire poison is too strong, with Su Yang's current strength, some can't carry it.

"Su Yang, you should feel lucky. This is the fire poison I collected in the extreme sun. After my modulation, it is more powerful. You are the first test object. Feel it well." The miracle doctor first took the antidote of Zhuyeqing to Su Yang, and then forced the fire poison into Su Yang's mouth. Seeing that the red breath was swallowed by Su Yang, the miracle doctor became extremely excited. He stared at Su Yang's reaction quietly and put his finger on Su Yang's pulse gate.

It's like swallowing a blazing flame when the fire poison enters the abdomen. It's burning. He feels like his body is going to be burned to ashes. Su Yang doesn't need acting at all. He just needs a normal reaction.

In just a few seconds, Su Yang's eyes turned red, which was terrible. His body turned red, as if he had been smoked by the fire. His body trembled violently, and the breath from his nose was tinged with red. Especially Su Yang's hair began to turn yellow and withered, as if he had been burned.

The miracle doctor who carefully observes Su Yang's reaction is very excited. He takes out a book to record Su Yang's reaction madly. Besides recording Su Yang's reaction, he also checks his pulse to find out how Su Yang's meridians react.
