Both of the masters were stubborn, and neither of them spoke first, and they both stared at each other steadily.

Master Rongyun's expression was calm, but Su Luo was breathing heavily, showing her excitement.

It seemed that after a long time, Master Rong Yun slapped Su Luo in the head: "You are so terrible, just like your mother."

When Su Luo saw Master Rongyun speak first, he knew that he had won. He couldn't help laughing: "Don't Master just like my mother's temperament?"

Master Rong Yun gave her a blank look. How could he only like Yanhua's temperament? He liked everything about Yanhua, including hair. But this is not suitable for explaining Su Luo, so he was silent and golden.

Master Rong Yun pondered for a while before patiently explaining to Su Luo: "Do you know what poison is in that kid?"

"What poison?" Su Luo's eyes were puzzled.

"Cold poison." Master Rong Yun replied calmly, "And it is the cold poison caused by the ultimate yin. There is no cure in the world, only--"

"What's the only thing?" Su Luo asked anxiously.

"Only..." Master Rong Yun lowered his voice and said a low voice in Su Luo's ear. Then, he calmly picked up the teacup and savored it carefully, as if it was the sweetest tea in the world.

Su Luo sat blankly in the spot, slowly, the expression on her face gradually turned a little red.

"Master, how could it be..." Su Luo couldn't believe it, "How could there be such a treatment method?"

Su Luo found it unbelievable.

"Whose apprentice is that kid?" Master Rong Yun asked indifferently.

"The Lord of Purgatory City." Su Luo replied in a daze.

"Do you think, with the power and means of the lord of Purgatory City, why can't he cure his disciple's illness?" Master Rong Yun asked calmly again.

Su Luo suddenly realized. Yes, with the strength of the lord of Purgatory City, how could he allow his personal disciples to have hidden diseases? However, Nangong Liuyun's hidden diseases still exist until now, what does this mean?

This shows that even the lord of Purgatory City has no choice but to do with this disease.

"Ten years ago, Long Qingtian brought him to find a teacher." Master Rong Yun's voice was faint, and he fell into a long-standing memory. "Although Master is not in harmony with Long Qingtian, it is not right. At that time, Master once personally took the pulse of the boy and learned about the disease."

Su Luo suddenly realized in his heart.

No wonder the master knew that Nangong Liuyun had a leg disease without looking at it, and he knew that he could not cure it himself. It turned out that his master had cured him ten years ago.

Su Luo opened his eyes wide and listened carefully to the stories told by his master.

Master Rong Yun continued: "The cold poison in his body is very strange, as if... sealed some violent power, which is very terrifying."

"What?" Su Luo suddenly stood up. Even the master said that the power was terrifying. So, how terrifying the unknown power in Nangong Liuyun's body was.

"Once the seal is lifted, the silly boy's leg fatigue will be cured without medicine." Master Rong Yun's eyes were deep and deep like the sea. "And one of the methods to untie the seal on him is what the master told you just now. However, when using this method, you must be a master-level alchemist, otherwise you will not be able to withstand it and die of explosion."

Speaking of this, Master Rong Yun's eyes were extremely strict, like thousands of years of ice: "So, before the moment of a master-level alchemist, you must protect your own body, do you understand?"
