However, in order to form a seal on a person without being noticed, the object used to form the seal must be something that the other person already possesses.
If the seal is made with something like metal, it will be very obvious on the enemy and will definitely be noticed.
"What is it that the enemy possesses that will not be detected?"
Xiao Shi fell into deep thought.
Suddenly.
A flash of lightning seemed to flash through his mind.
“I figured it out!”
"Qi and blood!"
"As long as I use my own energy and blood to form the seal, it will definitely not be noticed!"
Xiao Shi felt that his idea was highly feasible.
After all, everyone has qi and blood.
When the mark formed by the condensation of qi and blood appears on the other person's body, it will be like a part of the other person's qi and blood and will be difficult to detect.
As long as it is hidden properly and the mark is not condensed where the enemy can see it, it will not be detected.
“You can give it a try!”
Xiao Shi felt excited.
If one could condense an undetectable mark of Qi and blood on another person, then one would undoubtedly have an additional powerful means of assassination!
In the future, even if you encounter an enemy stronger than you, you can hide in the dark and launch a sneak attack by detonating the mark!
However, whether it is feasible or not will only be known after he tries it.

The mark is invisible to the naked eye because it is covered by clothes.
Xiao Shi observed the two of them silently.
I found that they didn't have any abnormal reactions and were completely unaware that I had left marks on their bodies.
