On the way back to the cockpit, Chen An ordered the passengers to return to the train one after another, and he took the time to check his new abilities.

[Spiritual Brand: Imprints a spiritual brand on another creature, ensuring they will never betray you. This branding can be repeated as many times as the number of Spiritual Strings. After branding, you can connect or couple with them at any distance, and can also establish spiritual connections beyond dimensions.]

Compared with the quantum teleportation and racial disguise he had obtained before, Chen An still felt that this was more useful.

The four words "never betray" are valued by all those in power.

"I now have over a hundred spiritual strings, which can make an equal number of people absolutely loyal to me. It's extremely useful."

"The greater benefit is that there is no distance between me and the target who has been mentally branded. I can contact them at any time, which is very useful in war."

Chen An was very excited and immediately used Qianqiu for experiments.

The method of use is quite simple. Release the spiritual string, tie a few knots in some particularly mysterious way, and then look for Qianqiu.

Qianqiu was playing outside the department and she didn't feel anything unusual until she heard Chen An's voice in her mind.

"Hey, brother, what's wrong?"

They usually communicated like this, so it wasn't strange to Qianqiu.

Chen An didn't say anything, they were in direct mental harmony and everything went smoothly.

After the conversation, Chen An concluded, "I'm like a server, connecting others via the internet. Fuyao, how do we test the effect of Never Betray?"

【Only time can tell】

"You're right, this thing can't be tested."

In order to facilitate communication, Chen An also planted spiritual imprints on Fei Yi and Luo Yu.
