Bi ran apologized and bowed in front of Lu Yu with a solemn expression:

"Mr. Lu, I owe you a life. I will pay it back in the future!"

Cough!

"Brother Bi, you are a nurse. I don't blame you, but I admire your sincerity!"

Lu Yu covered his chest and coughed a few times, smiled and said:

"In fact, I also have the responsibility. In order to achieve the best treatment effect, I can't inform you in advance, so that you misunderstand!"

Bi ran took a towel, carefully wiped the blood on the Dragon King's face, and said to Lu Yu in disbelief:

"My master, this is... This has been restored?"

"How is it possible that I just activate the breath in the Dragon King's body and his will to survive, but the poison he was poisoned was the culprit leading to his paralysis!"

Lu Yu smiled bitterly and said his judgment!

"Mr. Lu, do you know what poison this is?"

Bi ran saw that Lu Yu shouted out that his master was a symptom of poisoning, and immediately asked him eagerly.

At the moment, he no longer despises and believes in Lu Yu's medical skills. From the beginning to now, Lu Yu has neither pulse nor check the body data of the Dragon King. It is reasonable that he should know nothing about the Dragon King!

However, Lu Yu first used words to arouse the Dragon King's will to survive, and then activated the Dragon King's breath. Now he has diagnosed that the Dragon King's paralysis is caused by poisoning, which is incredible!

Because the Dragon King is really poisoned!

In the past ten years, they have traveled all over China. They have found almost all famous traditional Chinese medicine and trusted western medicine, but no one can say what poison is in the Dragon King!

It can only be judged that this kind of poison is chronic. Although it spreads very slowly, it has been spreading silently, but it is very difficult!

This kind of poison, like a cold poisonous snake, is encroaching on his master's muscles and internal organs bit by bit, which has turned his master into a useless man!

The magnificent Chinese god of war even needs help to go to the bathroom, which is undoubtedly worse than death.

Fortunately, Lu Yu was invited. Although the Dragon King has not recovered yet, his will to survive has been restored and the breath in his body runs again!

I believe it is not far from the day when the Dragon King recovers!

"Thank you. I owe you a favor. If you have something, you can come to me through Bi ran. Let's calculate the interest first."

At this time, the old Liu put away his cynical look and said gratefully to the landing feather. Then he took out a dark metal sign from his arms and stuffed it in his hand.

"Thank you, Mr. Liu. You're so kind. It's my bounden duty to save the lives and heal the wounded. I..."

Lu Yu quickly declined. Looking down, he saw that the brand was made of metal, with two big characters written in Mao Kai: inverse scale!

"Liu Lao, is this an inverse scale?!"

Before Lu Yu finished, Bi Ran's face jerked and his eyes were full of shock:

"I also hope you will consider carefully. The power of inverse scale is too great. If it falls into the hands of bad people and uses it to commit crimes, the consequences will be unimaginable!"

"Liu Lao, this brand is of no use to me, and it's so important. You'd better take it back. I didn't save the Dragon King for power."

Lu Yu holds the black iron sign and wants to hand it to Liu Lao. At the same time, he looks at BI ran with an unhappy face and wants to ask him, what is if he falls into the hands of a bad person?

Do you look so bad?

"I believe in Dr. Lu!"

Liu Lao didn't take the sign, just nodded, and then jumped out of the window.

"Don't get me wrong, Dr. Lu. I know you're not a bad person. I'm just afraid you can't keep it. This brand is very important and must not fall into the hands of bad people."

Bi ran quickly explained that he pointed to the black iron card in Lu Yu's hand:

"This card is called inverse scale. It is made by the Dragon King himself with an unknown metal. It is the only one in the world. The most important thing is that the Dragon King has vowed that whoever holds the inverse scale, such as the Dragon King himself!"
