Chen Chenyu helped the person to the couch.

"Let's get started." Qin Tianhen looked determined.

If the last injury hadn't caused the old injury, I'm afraid he would never be able to take out the arrow inside.

Sometimes I think about it, he is too stubborn.

"Grandpa, I just need to take a nap in a while." After Chen Chenyu changed into surgical clothes, he carried the medicine box to the bed.

Qin Tianhen frowned, "Get some sleep? Do you want to give me Ma Fei Powder?"

It is said that the stuff is similar to wine. As long as you drink it, you can fall asleep immediately. You can't wake up even if you scream. You can't feel any pain. Even if you are hit with a stick, you won't feel it.

"It's not Ma Fei Powder, it's something even more effective than Ma Fei Powder." Shen Chenyu opened the medicine box and prepared to take the anesthetic.

Qin Tianhen waved his hands repeatedly, "I don't need that thing."

"Grandpa, whether it's taking out arrowheads or scraping bones and flesh, the pain is unbearable for ordinary people."

"It's a joke. I have been on the battlefield all my life and have countless injuries on my body. What does this little pain mean?" Qin Tianhen sneered.

Besides, he also wanted to see with his own eyes how this girl took the arrow out of his body. If he drank that thing, he wouldn't be able to see anything.

"Okay." Chen Chenyu agreed, "However, if grandpa feels unbearable pain later, he must tell me."

"Stinky girl, how dare you look down on me?" Qin Tian was so angry that his beard trembled slightly.

"It's not that I'm looking down on grandpa, but we have an instinctive reaction to pain. If during the process of taking the arrow, grandpa's body trembles due to pain, it will affect his ability to take the arrow."

"Don't worry, even if you remove my bones, I won't even blink."

Chen Chenyu was relieved.

When she took out the surgical tools from the medicine box, Qin Tianhen was slightly surprised, "I didn't expect you could fit so many things in this box."

After that, without further investigation, he tore off his sleeves and exposed his entire arm.

Before the operation, Shen Chenyu activated the medical system and checked again. However, this time her face changed drastically.

"The arrow is missing!"

"Impossible, that thing has been in my body for ten years and has grown together with the bones. There is no way it will disappear!"

However, the medical system clearly stated that there was indeed no arrow on his humerus.

"Grandpa, I heard that you had an accident on the way back to Dongli from Shengjing last time. Was the accident... an arrow in your right arm?"

Qin Tianhen nodded, "If it hadn't been for the injury last time, my arm wouldn't have been so serious."

"I guess the arrow shot out of your body was shot out last time."

Qin Tianhen frowned and thought deeply, and did not speak for a long time.

The arrow last time was so powerful that it almost penetrated his entire arm. It was not impossible to shoot out the arrow inside. But if there was no arrow in his body, why would his arm become more and more serious?

Could it be that...the arrows from last time were poisonous?

Suspicion flashed through his heart when Chen Chenyu told him clearly, "That arrow is not poisonous. Years of grinding on the previous arrow had already caused humeral necrosis. This time the injury was just an infection that caused the inside of the humeral bone to become necrotic." Sores and pus.”

After Shen Chenyu explained, he raised the knife and made a gash on Qin Tianhen's arm.

"Hiss!" Qin Tian was caught off guard and frowned fiercely, "It's not like there are no arrows inside, so why are you still operating?"

"As I said just now, grandpa has abscesses and rot in his arms and needs to be removed."

Chen Chenyu raised his eyes as he spoke, "Do you want to use anesthetic?"
