Zhou Yu held the silver needle and swiftly inserted it.
In an instant, Zhao Jianlong's body was filled with silver needles.
Then, Zhou Yu placed his palm on Zhao Jianlong's forehead, and his True Qi slowly flowed into Zhao Jianlong's body.
As Zhou Yu injected his True Qi, Zhao Jianlong's body began to emit streams of gas.
These gases appeared blackish-gray, clearly indicating they were toxic.
Zhou Yu turned to Zhao Jian and Zhao Fei'er and said,
"Both of you, step back, don't breathe in these gases."
Zhao Jian and Zhao Fei'er quickly retreated to the door, while Zhao Jian had a servant fetch masks to wear.
By now, Zhou Yu was fully absorbed in the treatment.
The poison within Zhao Jianlong's body was hidden throughout his meridians; by using the silver needles, Zhou Yu was able to channel True Qi into these meridians, forcing the poison out.
This might sound simple, but controlling True Qi required extremely high precision.
