"So that's how it is," Hou Guoyi nodded. "Then tell me, how should I treat this illness?"

When he asked this question, the surrounding people couldn't help but take a step closer. For the entire Hou clan, Hou Guoyan's illness was an important problem, and this problem had troubled them for many years.

But now, Zhang Yu's arrival gave them hope for the treatment of this disease. How could this not make them anxious and look forward to his arrival?

"According to my understanding, the reason why Uncle Hou is in such pain is because there is a shard hidden within your bones." Zhang Yu said confidently.

"Fragments of shrapnel?" Hou Guoyong looked at his brother, shook his head and said, "How is that possible? My brother was shot before, but the bullet in his body has already been removed. How can there still be a bullet left in there?"

"It's not a shrapnel, it's a shrapnel," Zhang Yu explained. "It's a very, very small shrapnel, a few millimeters of that kind of shrapnel. It's already cut in there and merged with the bone."

"Didn't you just say that this can be treated?" The old man said.

"Yes, I've said it before, but it's too difficult to take out the fragment. I can't guarantee that I'll succeed in doing so," Zhang Yu said honestly. "But I have another way to treat it."

"Oh, what is it?" The crowd asked in unison.

"Turn this shard into powder, and let it completely merge with the bone. This way, it won't pierce the bone, causing continuous pain, and it won't have any side effects on the body."

Zhang Yu had considered this carefully. With his perspective, he could clearly see the location of the shrapnel fragments and turn them into fragments. For Zhang Yu, there wasn't much of a problem.

"In that case, what do we need to prepare?" Hou Guofong asked.

"I don't need too many things. I need some basic disinfectant items, hemostatic cloth and the like. The most important thing is to have a set of acupuncture needles."

Zhang Yu said to Hou Guang, "These things should not be difficult to obtain. As long as we can obtain them, I will be able to make my move immediately."

After Zhang Yu wrote down the basic list, in less than half an hour, all these items were placed in front of Zhang Yu.

To be honest, Zhang Yu didn't use acupuncture often. The last time he used a silver needle, it should have been half a year ago. Now, he was about to use it on a high-ranking military officer.

"Everyone, don't stay here. Everyone, watch. I'm quite nervous." Zhang Yu said embarrassedly.

"How about this, let's go to the room upstairs. It's quiet there." Hou Guofong said.

Zhang Yu nodded and went up to the second floor with Hou Guoqiang, Hou Guoyi, and a few others.

"Uncle Hou, show us the wound!" Zhang Yu asked after seeing that everything was ready.

Only then did Hou Guoyi take off his pants, revealing his entire right leg. There was a shocking spot above his knee. This place was dyed black and red, and the scars were very obvious.

Apart from this, the rest of his body was not simple either. Although his leg was only exposed, there were many potholes and potholes all over the place.

"This is …" Although Zhang Yu was used to these wounds, he was still shocked by them.

At first glance, it looked as if his leg was covered with worms.

"These were all left behind by my big brother when he was on a mission in the past. Many years have passed in the blink of an eye. These must be the traces of his time!" Hou Guofong sighed with emotion.

In his heart, Zhang Yu also felt admiration for this grandpa. Indeed, it was not easy to achieve such a position!

"Sigh, it's already in the past, why are you still bringing it up?" Hou Guoyi waved his hand nonchalantly. Then, he turned to Zhang Yu and asked, "Young man, tell me, how do you plan on making a move?"

Zhang Yu honestly said, "My method is very straightforward. It is to use this small silver needle to pierce through your body and grind the fragments of your body bit by bit. This process will definitely have a sore spot, so I suggest that before you start, you should take some anesthetic."

"I don't play with that thing." Hou Guiyi rejected very straightforwardly, almost without any thought, "This anesthetic's anesthetic nerves can affect one's intelligence. Moreover, I'm a person who has fought in war and experienced life and death, can't I endure such a small pain?"

Zhang Yu asked, "Are you sure?"

"I'm sure!" Hou Guoyi nodded.

"Alright, since that's the case, let's begin!"

Zhang Yu turned around and told Hou Ge, "Uncle Hou, please guard the door for us. Don't let anyone in. Don't worry, it won't be long."

"Alright, leave it to me," Hou Guofong nodded and said, "Calm down and treat my big brother!"

Zhang Yu took out a silver needle and disinfected it. Then, he aimed at the wound.

"Uncle Hou, it's about to begin."

Zhang Yu reminded him before slowly stabbing the needle into the wound.

At first it didn't pierce too deeply, nor did it pierce into the vital areas, so it didn't hurt.

Zhang Yu's eyes were fixed on the location of the shrapnel. A silver needle had pierced into his knee from the front and another had stabbed into the back.

Two silver needles, one in front and one behind, were placed between the silver needles.

"Uncle Hou, bear with it. It will be very painful next." Zhang Yu reminded him.

"It's fine, just do your job, I can bear with it." Hou Guoyi said.

Seeing this, Zhang Yu no longer hesitated. One in front and one behind him, he grabbed two silver needles and exerted his strength at the same time. A small crack suddenly appeared on the shard in the middle.

At this point, Zhang Yu finally heaved a sigh of relief.

But at this moment, Hou Guiyi was no longer as relaxed as before.

At that moment, it was really painful to the point where his teeth were chattering and he sucked in a few breaths of cold air. Fortunately, he did not cry out, Hou Guoyi thought to himself.

Looking at this small crack, Zhang Yu used two silver needles to continuously grind the surroundings of the fragment, turning it into powder little by little and then disappearing into his flesh and blood.

Even if it was just a few millimeters away, it still took Zhang Yu an hour and a half. During this hour and a half, he was exceptionally careful, afraid that something might happen to him.

And as a patient, Hou Guoyi was obviously more tormented than Zhang Yu.
