"It's okay, I'm just cleaner. ”

After hearing this, Xie Xun noticed Su Qing's somewhat hesitant gaze and shook his head slightly.

"Grandfather, we'll be back soon. Su Qing said with a frown.

Su Heng and Su Qing walked out the door.

"I wonder if my grandfather used to have similar symptoms to my mother?"

"It seems like it is. Hearing Su Qing say this, Su Heng subconsciously recalled that this was indeed the case.

Although he went to join the army three years ago, he still has some understanding of the old man's situation.

"My sister is saying... This hairpin has been poisoned, so my grandfather and mother have similar symptoms?" Su Heng suddenly realized, and looked at Su Qing with a pair of eyes.

Su Qing nodded solemnly.

"That's right, and this poison is chronic, and there is nothing unusual about exposure to it for a short time, and by the time the symptoms appear, almost everything is too late, and no one will blame the source on this inconspicuous little object. ”

"But ......" Su Heng frowned: "At that time, I retrieved my mother's relics for my grandfather, and I also suspected that someone would poison her jewelry, so I specially asked the doctor to check it, but it turned out that these were safe." ”

For a time, the atmosphere was deadlocked.

Su Heng is very willing to believe Su Qing's words, but the doctor who can be investigated is also trustworthy by their side.

Although Su Qing has a lot of almost expressive deeds, he is only twenty-eight years old, and compared with those doctors who have been practicing medicine for many years, I am afraid there is still a gap.

"That's the genius of this poison. Su Qing didn't refute what they said, but asked again: "Does my grandfather's house often light some charcoal fires?"

"When people get old, they are very afraid of cold, so in the summer, they should also be a little bit warmer in the house than outside. Su Heng knows a lot about this matter.

When Xie Xun was young, he often played among the mountains and rivers in search of inspiration, even in the scorching heat and cold winter, he would often wear a thin single coat inside and a big jacket outside.

When he was young, he didn't know what to suffer, but when he got old, the root of the disease fell, which also caused him to be extremely cold, even in the rainy weather of summer, his legs hurt as if they had been smashed by a hammer.

Therefore, whether it is summer or winter, his house is warm.

That's right, the brilliance of this poison is that although it is applied to the surface of the hairpin, it will not be detected under normal circumstances, and the real poison is the gas it volatilizes at high temperatures. ”

Su Qing nodded, and all the problems seemed to be solved.

"Volatile gases?" Su Heng repeated with a frown.

"You can understand it as water vapor, boiling water in a cauldron, and when it burns to a certain level, the water disappears, and then the water becomes water vapor, which we can't see, but it does exist. Su Qing knew that they didn't understand these common senses, and patiently explained.

"What does Qing'er mean...... The temperature in this room is too high, so on the hairpin, the poison that was originally not poisonous becomes something similar to water vapor, which we can't see, and then it is gradually absorbed by me?"

Su Heng pondered for a moment, and soon understood the principle of this.

"Clever. Su Qing nodded: "If ordinary poison only covers the surface, it is impossible for it to last for so long, the only possibility, this hairpin has been poisoned for many days from the inside out, and it has already entered the wood." ”

After Su Heng heard this, there was no relaxation between his eyebrows.

Who would have thought that the one who killed his grandfather was actually just a small hairpin.

"Now this poison can't be left, and if it is left, it can only harm more people!" Su Heng said this, his heart was ruthless, and he raised his hand to break it.

But he was stopped by Su Qing.

"After all, this is also my mother's relic, although it has been covered with poison, but it is not impossible to get rid of it, but it is simple to remove the poison on the hairpin, but my grandfather is a little difficult. When Su Qing said this, she couldn't help but sigh.

These things should have nothing to do with the Liu family, but they don't want to be self-defeating, if it weren't for Xie Xun bringing it back, they wouldn't have found out.

"Grandfather..."

Su Heng sighed, his face was very solemn.

"No, grandfather, I can be cured, give me a little time, and I promise him will be healed. Su Qing shook her head.

Although it is somewhat difficult to treat with ancient medical conditions, it is not impossible, and the risk is higher, which is better than dying.

"Really?" Su Heng didn't know how to say it, as if a long-drought desert met Ganlin, and everything had hope.

"It's just that don't tell my grandfather about this matter first, if my grandfather asks about the hairpin, he will say that I like it, take it to play with it for a few days, and return it afterwards. Su Qing nodded and couldn't help but say softly.

"Qing'er has a heart. ”

Su Heng understood what she meant, and was shocked in his heart, only feeling that the little girl who used to cry when she encountered things was now able to take charge on her own and become a slim girl.

Suddenly, Su Heng had a feeling that my family had a girl growing up.

Back in the room, Xie Xun was lying on the bed, looking tired.

"Grandfather, although you have an old problem, it can be cured, just because you don't use the right method. ”

"Really?" Xie Xun was a little suspicious, but there was also a light of hope in his eyes.

"Nothing was too much trouble. Su Qing's eyes were firm, and what she said was also sonorous and powerful, which was inexplicably convincing.

Xie Xun looked at Su Qing, opened and closed his lips several times, and did not spit out a word.

Even though there are a thousand words in my heart, but when the words come to my mouth, I don't know how to express them.

This affection is too deep and too restrictive.

The three of them chatted for a long time, and the sun at the head also set on the mountain, and it was getting late.

"Qing'er, let me ease myself during this time, and when you and Su Heng come together after a while, I will tell you something...... What I should have told you a long time ago. Xie Xun raised his head and looked at the sky.

"Good. Su Qing looked at him and nodded slightly.

After greeting for a while, Xie Xun's eyebrows and eyes were obviously a little tired, but he still spoke to the two of them with a strong smile.

"Grandfather, rest well, I'll come back to see you another day. ”

Although he was a little reluctant, Su Qing knew that what Xie Xun needed most now was rest.

Seeing Su Qing's back go away, Xie Xun couldn't help but sigh: "The little bun that used to be timid and crying has now grown into a slim girl." ”

"My sister is very good and strong, and when I first went to see her, I almost didn't recognize her. Su Heng nodded, and subconsciously rubbed his shoulders for Xie Xun.

"Su Qing, this child, will definitely be better than your mother in the future, but I'm afraid that you, a man, can't compare to her. Xie Xun's eyes remained unchanged, as if he was sighing.

"He is so good, he must have suffered a lot of grievances, but it's a pity that the two of us didn't stay with her. Su Heng regretted in his heart and was very distressed about Su Qing's situation.
