Seeing Nan Ao coming over, Yi Chen hurriedly saluted: "Senior, take the liberty to ask, are you from the Medical Sect?"

"Why do you ask that?" Nan Ao didn't answer directly, but asked with a smile.

"The little woman who used to deal with the monster just now should be a drunken fan, except for the disciples of the Medical Sect, there are very few ordinary people. Yi Chen said, "And you know the location of the monster's gallbladder very well, you must be a master of healing." As for this beast's gall and beast's heart, except for using it in medicine, I'm afraid there is no other use. ”

Nan Ao nodded slightly to Yi Chen, but did not speak.

"That's good, you're pretty smart!" Nan Ye said to Yi Chen, "Let's go!" That monster was intoxicated, and it tossed it again just now, and it won't go far before it falls to the ground. You accompany me to get the heart of the beast!"

"Aren't you going with you, senior?" asked Yi Chen a little surprised.

"The monster has attacked the mountain village, and it will bring diseases, and my grandfather will go to the village to deal with it. Nan Ye said to Yi Chen, and then turned to Nan Ao: "Grandpa, let's go first!"

"Go ahead!" Nan Ao said to Nan Ye and Yi Chen.

"What's your name? Are you really from the Medical Sect?" asked Yi Chen on the way to find the monster.

"My name is Nan Ye, you can just call me Ye Zi!" Nan Ye said, "I'm not from the medical sect, my grandfather is! I'm still young, and I can't apply for the sect yet!"

"My name is Yi Chen. Miss Nan, can you do me a favor?" Yi Chen asked, looking at Nan Ye.

"What kind of boy girl and girl girl, call me Yezi!" Nan Ye said angrily.

"Okay, Yezi, can you help me get something from your grandfather?" asked Yi Chen.

"What is it?" Nan Ye asked, "If he had it, he would give it to you, my grandfather is generous!"

"Blue Spirit. Yi Chen said, "I heard that the disciples of the Medical Sect all carry this thing on their bodies. ”

"No problem, when we find the beast heart, just go back and ask him directly!" Nan Ye said, it seemed that this was a trivial matter to her.

The two followed the monster's footprints for half an hour, and finally found the monster lying on the ground by the river at the foot of the mountain.

Nan Ye took out the beast heart in the same way, and asked Yi Chen to go to the river to wash the dagger, long rope and beast heart, and then return to the mountain village to find Nan Ao.

When Yi Chen and Nan Ye returned to the mountain village, Nan Ao was already waiting for them at the entrance of the village, and it was obvious that his affairs had been taken care of.

"Grandpa, Yi Chen wants to ask you for Lan Lu. Nan Ye said directly to Nan Ao.

Nan Ao looked at Yi Chen suspiciously and asked, "What do you want Lan Lu to do?"

"Blood test!" replied Yi Chen.

"Use the blue spirit blood test?" Nan Ao deliberately looked at Yi Chen in a puzzled tone and asked.

"There have been several great plagues in the history of the Terrans, and each time they have taken great losses to the Terrans. "There is no effective cure for this plague, but you can use a blood test to determine whether you have been infected with the plague." ”

"Oh, how can you be sure?" asked Nan Ye curiously. Because although she knew about the plague, Nanao never told her how to identify the plague disease.

"If the color of the blood does not change after five hours, it means that it is not infected with the plague, if the color of the blood becomes transparent, it means that it has become a plague disease, but it is still in the incubation period and is not infectious, and if the blood color turns green, it means that it has become a plague disease and is infectious. Yi Chen said.

"How do you know this?" asked Nan Ao, a little surprised. In the Medical Sect, only a Grandmaster-level person knew the secrets of the plague, let alone an outsider.

"I read it from an old book. Yi Chen said, looking at Nan Ao's expression, what the book said should be right.

"That's right, Blue Spirit does have this effect. Nan Ao said. He was already able to guess who the author of the book was.

"So that's the case, no wonder you have to take a blood test every year for a physical examination. Nan Ye suddenly realized, "But grandpa, why don't adults need to take a blood test?"

"For after the age of fifteen and fourteen years of age, a man will not be infected with the pestilence. Nan Ao said, "This is the reason why Huaguo set the age of adulthood and the age of applying for the sect examination at fifteen males and fourteen females. ”

"So, adults can't be infected?" said Yi Chen a little puzzled, "but the book ......"

"What the book says isn't entirely accurate. Nan Ao interrupted Yi Chen's words, "Because at that time, the person who wrote the book had not fully understood the full details of the plague. ”

After speaking, Nan Ao took out a blue spar from his body.

"Thank you, Senior Nan!" Yi Chen said in surprise, ready to reach out to pick it up.

"Wait!" Nan Ao said suddenly, "you have to answer me two questions first." ”

"Senior, please speak!" Yi Chen said.

"First question, whose blood are you going to test with Lan Lu?" Nan Ao asked.

"My own!" replied Yi Chen.

Nan Ao nodded and said, "Okay, the second question, what if you find out that you have a problem?"

Yi Chen said without hesitation: "I will kill myself, and I implore Miss Ye Zi to burn my body so as not to spread the plague to others." ”

Yi Chen felt that Nan Ye didn't blink even if she didn't blink her heart, and it should be difficult for her to do this.

"Huh?" Nan Ye exclaimed in surprise, "I won't do this, you burn it yourself!"

"Myself?" This will be Yi Chen's turn to be surprised, thinking to himself: How can I burn myself when I have committed suicide? Do you want me to set myself on fire?

"Let's talk about it after the blood test!" Nan Ao said as he tossed Lan Lu to Yi Chen, and then tossed him a transparent vial.

Yi Chen took the blue spirit and the vial, and prepared to put the blue spirit into the bottle, but the bottle mouth was too small.

"The blood test requires very little blue spirit, you smash the blue spirit first, it will be broken into small grains one by one, just put in one pill, and you can keep the rest yourself. Nan Ao said.

"Thank you for your advice!" said Yi Chen, then squatted down, spread a piece of cloth on a stone, and placed Lan Luo on it.

After smashing it, Yi Chen took one and put it in the bottle, and then asked Nan Ye to borrow a dagger, cut his palm, and dripped blood.

"That's enough!" Nan Ao looked at the blood in the vial and said, "Yezi, you can help Yi Chen bandage it." ”

Nan Ye sprinkled some medicinal powder on Yi Chen's palm, which instantly stopped the bleeding and reduced the pain a lot. She took out another piece of white cloth and bandaged Yi Chen's palm.

"If you're sick, you'll have five hours to live. Nan Ao looked at Yi Chen and said, "Do you have any other wishes?"

Yi Chen looked to the west and said, "I want to go to the desert land on the other side of the mountain." ”

"What are you doing in the desert?" Nan Ye asked a little puzzled, "That place should be deserted!"

"It was there that I was rescued eight years ago. Yi Chen said, "If you want to die, let me die there!"

"Why are you there?" asked Nanao.

"I don't know. Yi Chen shook his head and said, "I can't even remember what happened eight years ago. ”

"Let's go, we'll go with you!" Nan Ao said.
