After a stick of incense, Ye Chengyun had completely fallen asleep. But it would take a while for the numbness on his legs to fully work, so after waiting for about a cup of tea, Mu Qingnuan began to move again.

She put on a new pair of gloves and picked up the thinnest knife on the shelf.

She would first soak in the decoction and then burn it on the wine lamp.

Mu Qingnuan pursed her lips, took the knife, and directly hit the skin on Ye Chengyun's knees, and then continued to go deeper, directly into the flesh and blood, until the flesh and blood of Ye Chengyun's protruding place were cut, so that the protruding place was revealed.

"Hammer." Mu Qingnuan handed the knife back and said.

Ling Su handed Mu Qingnuan a hammer that was only about two-thirds the length of his forearm.

Mu Qingnuan took it and directly smashed Ye Chengyun's protruding and deformed bones......

Her uncle's leg was crushed by internal force earlier, but because it was crushed, there was basically no way to treat it, and she could only let the bone grow. As a result, the bones became deformed, and his uncle could no longer walk.

What she had to do at this time was to break the deformed bones that had grown into them again, and then restore the deformed parts to their original shape.

Reconnecting the broken bones has never been a thought of before, but it is the only way. At first, she didn't think of such a method, but when she read a lot of ancient books, she found that there were records in ancient books that people used iron knives, saws, files and other tools for some special treatment.

For example, in laparotomy, the patient's abdomen is cut open, the ulcers in his stomach and intestines are removed, and then sutured, and finally the wound is applied with a "divine ointment". The wound can be closed in four or five days after treatment, and it can be completely healed in about a month.

In addition to laparotomy, there are also bowel sutures, vascular ligation, nasal polyp amputation, etc., which are special treatments that cut the patient's flesh and flesh and then treat the affected area in the patient's body.

It's just that there are only a few words about these treatments, so it's hard to study. In her previous life, after she graduated from her medical skills, she studied for a whole year before she finally came up with a perfect treatment, but before she could implement it at the extreme, the disaster of destruction had come......

And this life.

Mu Qingnuan pursed her lips, her expression serious.

After Ye Chengyun's deformed bones were knocked open, he saw Mu Qingnuan taking the tweezers from Ling Su's hand, as well as a jade bottle.

When the jade bottle was handed over, it had been opened, and the black plaster inside. The plaster is called Black Blood Calcining Ointment, and its raw material is a black blood fish that grows in the polar regions. The polar regions are full of ice, but this fish can survive in the ice because of its special scales and blood.

On that day, she entered the palace to attend the birthday banquet of the fifth princess, and Ling Su was not by her side, because he was sent by her to find this fish. Fortunately, the hard work paid off, and Ling Su wasted a lot of effort before he finally succeeded in bringing this fish back.

That's why she had this bottle of Black Blood Calcining Ointment, and this ointment was a very good coagulation and adhesive plaster, and it was indispensable for her uncle's leg to be able to restore it.

Mu Qingnuan spliced back Ye Chengyun's broken bones, and every time she put back a bone, she had to apply black blood calcining ointment, and this process was very laborious, but after a while, fine sweat was already coming out of Mu Qingnuan's forehead.

Ling Su on the side looked at her, and according to Mu Qingnuan's instructions, she wiped her sweat expressionlessly......
