Control the divine sense to move on, and soon, Su Ling found the source of these black qi, Duanmu Qingtian's heart.

Ordinary people's hearts are not only red and clear, beating vigorously, but Duanmu Qingtian's heart is full of black gas, and there is also a state of malaise, just like a corpse that is being dried and will wither at any time.

In order to figure out what these black qi were, Su Ling injected all his divine sense into Duanmu Qingtian's heart, and after a while, he finally saw something abnormal: he saw an eight-legged spider as big as a thumb lying quietly in the corner of the heart, this eight-legged spider was completely black, it opened its mouth and bit a piece of flesh on its heart, absorbing the blood of the heart with all its might, and its stomach kept stirring, as if digesting these blood.

All the black qi in Duanmu Qingtian's body was emanating from this eight-legged spider.

Moreover, with the sucking of the eight-legged spider, Duanmu Qingtian's heart is gradually withering.

There is no doubt that this eight-legged spider is the culprit of Duanmu Qingtian's serious illness!

"What the hell is this eight-legged spider?"

Su Ling's brows tightened, and he fell into deep thought.

Su Ling was thinking about his master's previous teachings and his master's pathological notes, and suddenly remembered that his master once said that in the southern region of the empire, there is a sect of cultivation called 'Chiyou Sect', and they cultivate poisonous Gu evil insects, and there are rumors and records that when this sect cultivates poisonous Gu evil insects, in addition to using some animals as intermediaries, it will even use living people to refine Gu refining insects.

There are all kinds of poisonous Gu evil insects refined by the people of Chiyoumen, including golden cicadas, toads, poisonous snakes, and silkworm eggs...... And so on, one of them is spiders.

At this moment, the eight-legged spider attached to Duanmu Qingtian's heart seemed to be a bit like the evil insect eight-legged spider refined by Chi Youmen.

Historically, the people of this Chiyoumen are not only very mysterious, but also very evil, which is not tolerated by the righteous path of the Central Plains, so they have launched many extermination operations.

In order to survive, the remnants began to wash their hands in a golden basin, and from then on, they no longer used living people to refine Gu refining insects, and rarely used Gu insects to kill people.

Unexpectedly, in Hongcheng City in the Central Plains Region, there were people from Chiyoumen, and they also wanted to use this demonic Gu worm to kill Duanmu Qingtian, which was really rare.

However, these are not things that Su Ling should worry about, now that he has found the reason for Duanmu Qingtian's illness, it will be easy to deal with next.

To put it simply, Su Ling has 10,000 ways to revive Duanmu Qingtian!

Observing this, all the truth was revealed, and Su Ling withdrew his divine sense.

Slowly opening his eyes and removing his hand from Duanmu Qingtian's chest, Su Ling looked at everyone opposite with a smile.

Seeing Su Ling's smile, Duanmu Xue was in a good mood, and vaguely guessed whether Su Ling had found a way to heal her grandfather, and hurriedly asked, "Doctor Su, how is it?"

Su Ling nodded slightly and said with a smile: "I have found the cause of the disease, and your grandfather is still saved!"

"Really?" Duanmu Xue was pleasantly surprised, this was definitely the best news in the past half a month, "Is my grandfather really saved?"

"Well, I said yes, that's yes. Su Ling replied in the affirmative.

Not only Duanmu Xue, but even the people around him felt happy when they heard it.

"Ridiculous! ridiculous!" However, just when everyone was excited, Quan Yuanlong poured a basin of cold water on everyone, and he glared at Su Ling angrily, "You said that you have found the cause of the disease, and you have no use for any equipment, just press one hand on Master Duanmu's chest, so that you can find the cause?"

Originally, Su Ling didn't want to argue with him, but since he entered this room, Quan Yuanlong has been aggressive, not only sneering at him, but also constantly questioning him, which makes Su Ling also a little disgusted with this person who thinks he is the number one in the world, so he has to fight back.

With a cold smile in his heart, Su Ling said, "What, I used my divine sense to check Master Duanmu's body, isn't it okay?"

"Divine Sense??" Quan Yuanlong's face was full of doubts, and then he laughed disdainfully, "Haha! I actually even said such a legendary ethereal thing as Divine Sense, boy, do you think you are telling a fantasy story? Or are you telling a story about cultivating immortals?"

Su Ling pursed his lips and said, "What do you like to think it's your business, anyway, I've already found the cause, that's enough!"

"Really?" Quan Yuanlong asked, "Then tell me, what is the cause of Master Duanmu?"

"It's a Gu worm!" Su Ling put away his smile and looked at Duanmu Xue, "The reason why Master Duanmu is so seriously ill is because someone has a Gu in his heart, and an eight-legged spider is attached to his heart, sucking the blood of his heart, and releasing toxins, wanting to put him to death!"

"Haha! Joke! It's a big joke!" Quan Yuanlong raised his head and laughed twice, and said, "I see that you really have watched too many fantasy movies, Master Duanmu is so seriously ill, it is obvious that he has cancer! And he has reached the terminal stage of cancer! This kind of heart cancer is appearing on his heart, causing his heart to gradually age, malaise, and finally die!"

"Quack!" Su Ling rolled his eyes and cursed.

"You-" Quan Yuanlong's face trembled with anger, "Okay, good, boy, you said just now that you have a way to cure Master Duanmu, so why don't you try it?"

Speaking of the back, Quan Yuanlong smiled playfully, as if he wanted to see Su Ling's jokes.

Su Ling was about to agree, and began to heal Duanmu Qingtian, but suddenly wanted to give this Quan Yuanlong a little bit of power, thought about it, and said with a smile: "Quan Lao, if I can save Duanmu Lord, what should I do?"

"Hmph!" Quan Yuanlong saw Su Ling's thoughts, "Since you want a colorful head, then I'll give it to you! If you can save Master Duanmu, then I'll kneel down and call you Master! From now on, I will worship you as a teacher!"

After a pause, Quan Yuanlong smiled contemptuously: "However, if you can't save Master Duanmu, then you can kneel down and call me Master, and from now on, ...... Oh no, I don't want to take you as an apprentice, I'll just get me out of this room at once, that's fine, what do you think?"

"Is this?" Now Su Ling himself is still someone else's apprentice, and he doesn't want to accept any disciples, but he wants to see how this world-class first person kneels down and calls him a master, so he nodded, "Okay! Then let's say it first, anyway, Miss Duanmu is here, presumably you can't play tricks." ”

"You'd better take care of yourself first!" Quan Yuanlong had a win-winning expression.

He didn't believe that there was anyone in this world who could save a person from the hands of a god of death with terminal heart cancer.

If there is, then this person is not a man, but a god!
