The reconstructed tendons were bound to be much stronger than his previous ones and would significantly improve Zhao Chong's strength. This was Su Yang's way of expressing his gratitude to him.
After forcing out all the pus, Su Yang promptly used silver needles to seal the nerves near the wound. This way, Zhao Chong wouldn't feel any pain. Then, Su Yang used his True Qi to guide the severed tendons to slowly connect back together.
The tendons had been cut for more than seven days, and the severed ends had already atrophied. Normally, reattachment would have been impossible.
But for Su Yang, this was not an issue at all. Once he connected the torn tendons, he took out a medicinal pill from his body, crushed it, and sprinkled some of the powder over the joint.
