"Yuzhi, what Xiao Yu said does make some sense, you better let him help check it! He is not just scaring you, he healed the uncle's leg injury at the beginning, so his medical skills must be fine, you can rest assured!" Lin Hai saw that Guan Yuzhi's expression was somewhat relaxed, and hurriedly pulled her to explain. [No pop-up novel network]

"This ...... Well, since Xiao Yu wants to try, let's try it! Anyway...... Anyway, I'm sure there won't be anything wrong with me!" Guan Yuzhi had already softened in his heart, but he still refused to admit defeat on his lips, and said angrily.

Coming to the table and sitting down, Guan Yuzhi stretched out her hand in front of Lin Yu, seemingly calmly asking him to give her pulse, but the slightly tense corners of her mouth leaked the tension in her heart.

"Sister-in-law, you take it easy, it's just a pulse, and it's not an injection for children, it's not a big deal. Lin Yu explained with a smile, then stretched out two fingers and put them on Guan Yuzhi's wrist veins, and began to concentrate on the diagnosis.

After a while, the expression on Lin Yu's face changed slightly, and it became slightly unnatural--Guan Yuzhi's pulse was a little strange! On the surface, it seemed to be very stable and unusual, but there was a trace of weirdness hidden in it.

If it weren't for the fact that he was a human being in two lives, he was meticulous in diagnosing the pulse, and with the help of Yuan Li, he would almost not be able to judge it by just relying on the normal pulse.

It seems that the problem can't be detected just by diagnosing the pulse, Lin Yu remained silent on the surface, quietly drew a trace of Yuan Force from the dantian, and urged it to enter Guan Yuzhi's body through her fingertips, because her strength was only in the middle of the Yellow Order, and her own technique was relatively subtle, so she was not aware at all.

Patiently using this trace of Yuan Force, it circulated in Guan Yuzhi's body, and after a long time, Lin Yu finally found the problem.

However, this crux surprised Lin Yu!

When he detected Guan Yuzhi's dantian, he found that his sister-in-law's dantian was actually congested with a cloud of black gas!

This black qi floated and fell in the dantian, standing still, Lin Yu's vitality circled around the black qi, and carefully discerned its components, only to find that this black qi was actually a chronic poison called Jeno Grass!

This poison, which happened to be studied by Lin Yu when he was on Earth before, was called the Absolute Household Grass because it would make the user gradually lose his cultivation and be unable to continue to break through, and most importantly, it would affect the cultivator's fertility, resulting in the inability to give birth to an heir.

In addition, the Jeno Grass did not have the slightest effect on the life of the user, so Lin Yu used to think that this thing could only come in handy in the harem battle, but he didn't expect that today, it was encountered on his sister-in-law's body!

And according to the development of this black gas, it seems that it was just taken not long ago, and it is about the situation of the past two years, that is, after Guan Yuzhi married into the Lin family. Could it be that someone wants to deal with the Lin family, or is it impossible to close the family?

It's not difficult to treat the poison of this desperate grass, but it takes a little more time, and the most important thing now is to know who is behind the scenes and wants to frame the sister-in-law. Lin Yu's mind was racing, his mind was spinning rapidly, the expression on his face was also cloudy and sunny, and the atmosphere in the room was a little solemn.

Since Lin Yu couldn't come up with a conclusion for a long time, Guan Yuzhi waited a little impatiently, and simply took the initiative to ask: "Xiao Yu, have you found out anything? Why is your face so ugly? Could it be that I have a terminal illness that cannot be cured?"

"Bah, sister-in-law, don't guess, how can it be so easy to think of a terminal illness?" Lin Yu rolled his eyes and said with a nonchalant expression: "I have already found out, it is indeed your reason." It's just that because your constitution is weak and cold, the blood circulation is not smooth enough, so it is not easy to get pregnant. ”

"Is it as simple as that?" Guan Yu glanced at Lin Yu suspiciously, not quite believing the symptoms he described, always feeling that he seemed to be hiding something, but for a while he couldn't find other words to refute.

"Of course, sister-in-law, don't make a fuss, I'll prescribe a herbal recipe that nourishes qi and nourishes blood, and let the next person stew it for you, so that you can successfully conceive a baby in a few treatments!

The reason why he made up a random reason was that Lin Yu decided not to startle the snake for the time being, which alarmed the person who poisoned him, and also to avoid the eldest brother and sister-in-law from being suspicious and having trouble sleeping and eating after learning about it, and he had to find out the mastermind behind the scenes quietly and quietly!

"Yuzhi, since Xiao Yu said so, why don't you try it first!It's better than us sitting at home and being in a hurry!" Lin Hai said with his arms around Guan Yuzhi. He trusted Lin Yu a hundred thousand, after all, his heavenly eunuch was cured by him.

Although the color of the medicinal soup that Xiao Yu boiled at that time was a little strange, and I still remember it vividly, as long as it has an effect, isn't it okay?

"Don't worry, sister-in-law, I'll go to the pharmacy to dispense medicine, you can talk first!" Lin Yu nodded, and didn't want to say more, so he left the room and walked towards the pharmacy. Although her sister-in-law looks like a big man, like a female man, she is actually coarse and delicate, and she will see the clues if she is not careful, which is much more difficult to deceive than the eldest brother.

After simply mixing a few doses of qi-invigorating medicine in the pharmacy, in order to prevent someone from doing something hacking, Lin Yu personally supervised the people to boil the medicine, and then personally sent it to Lin Hai's room, and when he saw Guan Yuzhi drink the medicine, Lin Yu relieved his heart and turned around and walked to his grandfather's bedroom.

........................

"What did you say?" Lin Tianqing slammed his eyebrows into a frown, and shouted angrily.

"Grandpa, be quiet! I didn't tell my eldest brother and sister-in-law because I was afraid that they would be too excited and startle the snake, so don't do the trick!" Lin Yu hurriedly went to close the door and asked Lin Chen to look around to make sure that there would be no ears on the wall.

Just now, Lin Yu had already told Old Man Lin everything he had in his possession, and sure enough, Old Man Lin almost didn't go out after learning the news, after all, the secret enemy was fighting the idea of the Lin family's bloodline, how could Lin Tianqing calm down?

Seeing this, Lin Yu couldn't help but secretly rejoice, thanks to the fact that he only told his grandfather about this matter, if he told his grandmother, maybe she would rush out directly and kill all the enemies who might attack.

Lin Tianqing stood up, paced back and forth for two steps, and said in a deep voice: "Old Ge!"

"Subordinates!" a male voice suddenly came from the rooftop, sounding a little angry, but it was better to restrain it
