Zhang Lan got out of the car and looked at the courtyard in front of her, and her eyes became hazy with tears for a while.

Xiao Han looked at the courtyard in front of him and found that this was already the oldest courtyard house in the capital, but it gave people a sense of tranquility.

"Little sister, let's go. Father should be in a hurry," Zhang Long said as he looked at Zhang Lan who was about to cry.

Soon the three of them entered the courtyard, and the courtyard looked very clean. When the three of them walked into the main room, they saw the old man lying on the bed.

Xiao Han saw that the old man's temples were already gray, and his face was full of wrinkles, it seemed that this was his grandfather Zhang Zhan.

"Dad!" Seeing the person on the bed, Zhang Lan's tears broke the embankment in an instant, and she also ran over quickly.

"Xiaolan, Xiaolan is back" The old man on the bed turned his head and saw Zhang Lan and the others, looking at Zhang Lan excitedly.

In this way, the father and daughter finally met again, and their hands were tightly clasped together.

Xiao Han also saw a woman sitting next to the bed at this time, it seemed that this was his uncle's wife Liu Ling, that is, his aunt.

"It's back, Dragon. This is Xiao Han," Liu Ling looked at Xiao Han and said.

"Aunt" Xiao Han also called Aunt.

At this time, Zhang Zhan, the grandfather who was talking to Zhang Lan, also looked back at Xiao Han.

"Xiaolan, is this the son born to you and Xiao Zhan?"

"Yes, father, this is Xiao Han. Xiao Han, come and let your grandfather take a look at you," Zhang Lan said to Xiao Han.

Xiao Han had no choice but to take a few steps forward and came to Zhang Zhan's bedside.

"Okay, good, Xiao Han is really a talent" Zhang Zhan was also quite satisfied with Xiao Han.

In this way, Xiao Han and Zhang Lan can be regarded as returning to the Zhang family, and Zhang Lan has been chatting with Zhang Zhan.

"Ahem, ahem. cough, cough, cough" Suddenly, Zhang Zhan coughed violently.

"Father, what's wrong with you" frightened Zhang Lan and hurriedly patted her father's back.

"It's okay, it's okay, **I'm sick," Zhang Zhan stopped coughing and said.

"Uncle, what kind of illness does Grandpa have?" Xiao Han asked Zhang Long.

"Doctor, your grandfather has lung cancer, and it has reached an advanced stage," Zhang Long said with a gloomy look in his eyes.

Lung cancer? Based on Xiao Han's medical skills, it can be seen that grandpa should not have lung cancer.

"Grandpa, let me check your pulse, right?" Xiao Han said as he stepped forward.

"Oh, Xiao Han can still take the pulse," Zhang Zhan said and stretched out his hand.

Although I don't know if Xiao Han really knows how to take the pulse, how can Zhang Zhan refuse his nephew's little request.

Xiao Han checked Zhang Zhan's pulse, and a wisp of fire vitality directly entered Zhang Zhan's body, probing every part of his body.

In the end, Xiao Han's fire vitality stopped in Zhang Zhan's lungs. Sensing the situation in Zhang Zhan's lungs, Xiao Han suddenly frowned.

"Uncle, haven't you used your vitality to probe your grandfather's body?"

After Zhang Long heard this, his eyes suddenly widened like copper bells, of course, the reason was not because of the question Xiao Han asked.

But how could Xiao Han know that he was a martial artist, could it be that Xiao Han was also a martial artist?

"Xiao Han, how do you know that I am a martial artist? But I did probe your grandfather's body, but I didn't find anything. Zhang Long said.

"Actually, grandpa didn't have lung cancer, but Gu!" Xiao Han said a big secret after hearing this.

"What?" several people in the room were taken aback, apparently not expecting things to be like this.

"Xiao Han, what you said is true?" Zhang Lan said nervously.

Xiao Han didn't explain this, but once again put Zhang Zhan's pulse, and then Xiao Han directly released the Phoenix True Flame into Zhang Zhan's body.

Soon the Phoenix True Flame reached Zhang Zhan's abdomen, and at this time, Xiao Han could feel that there was a black insect lying in Zhang Zhan's lungs at this time.

Xiao Han guided the Phoenix True Flame, and with lightning speed, he wrapped the worm.

Then he went all the way up Zhang Zhan's trachea. Suddenly, Zhang Zhan coughed violently, and finally spit out the black worm.

"This, this is really a Gu worm?!" Zhang Long said when he saw the worm that his father spit out.

Then Xiao Han directly stepped on the Gu worm with one foot, and suddenly the Gu worm jumped out of green blood, and it splashed on the ground with a corrosive sound.

Then Xiao Han turned the fire energy into Zhang Zhan's body for a few laps before he stopped.

At this time, Zhang Zhan's face also became more and more ruddy.

"Dad, how are you?" said Zhang Long and the others excitedly.

"Grandpa's is not completely good, so I still have to recuperate for a while," Xiao Han explained.

"Xiao Han, how did you discover the Gu worm in your grandfather's body" Zhang Long looked at Xiao Han and felt more and more mysterious.

"Actually, I have a certain amount of medical ability, and then I don't want my grandfather to look like lung cancer."

"That's why I wanted to take a look at the pulse, and sure enough, after I investigated, it was the same as I thought."

"Grandpa didn't have lung cancer, but Gu worms. That's why I just used my vitality to get rid of this Gu worm," Xiao Han also explained.

Xiao Han was also wondering why his uncle hadn't discovered this Gu worm, but he had found it easily.

In fact, what Xiao Han didn't know was that the vitality cultivated by the martial artist was far less powerful than the fire vitality cultivated by the Nirvana Technique.

"Xiao Han, do you know what kind of Gu worm this is?" Zhang Lan frowned and asked.

"This is a Water Devouring Gu, as for why it's called a Water Devouring Gu. It starts with the lungs."

"We all know that in the five internal organs, the lungs are the main water, participating in the regulation of water metabolism throughout the body."

"And this Water Devouring Gu feeds on the lungs of the human body, but he doesn't directly eat the lungs of the human body."

"And after it enters the abdomen of the human body, it will first emit a toxin, which makes the person in the Gu look like he has lung cancer."

"This is not the case, this water devouring Gu is to let the person in the Gu slowly die under the infection of the toxin, and then directly eat the lungs of the person in the Gu"

After hearing this, several people felt a chill over this, they didn't expect this Water Devouring Gu to be so good.

"Father, how did you fall for this Gu worm?" Zhang Long asked suspiciously.

You must know that Zhang Zhan is now over half a hundred years old, and he usually stays at home, so this Gu person will not have a chance at all.

For a while, several people didn't completely figure out this matter.

"In fact, there is another major feature of the Water Devouring Gu, which is that it will die quickly after leaving the human body."

"This also leads to the fact that this Water Devouring Gu can't be directly put into the human body," Xiao Han explained again.

"So if you want to drop the Water Devouring Gu, you need to place the fertilized egg of the Water Devouring Gu in the Water Spirit Grass first."

"Then, after the Water Spirit Grass is eaten, this Water Devouring Gu will quickly eggify in the human body, and finally take root in the human lungs," Xiao Han said.

"Xiao Han, you're talking about the Water Spirit Grass" Zhang Long and Zhang Zhan were taken aback when they heard the Water Spirit Grass......
