At the same time, a giant light blue magic barrier that extended into the town and was buried underground was revealed in front of Lei Xiao and others.

"The magic power attached to this giant magic circle is extremely thin, and the magic lines on it are also very easy to understand. It can only transmit simple magic flow, and it will never be a dangerous mechanism such as a magic trap."

Hong Ye, who had been guarding Lei Xiao, her sassy voice then reached Lei Xiao's ears: "So, what is the function of this magic circle? Why are so many metal plates of unknown purpose placed?

"

"How amazing!"

Just as Hong Ye finished speaking, she saw Chao Yan not far away, jumping up and down and saying: "Lord, as long as you step on these metal plates, the magic array under them will transmit a flow of magic power to the center.

Woolen cloth!"

"oh?"

Lei Xiao, who had also been frowning in thought, heard the sound and immediately rushed to where Chao Yan was.

The moment this girl jumped up and landed on the metal plate, the light blue magic circle underneath it flashed quickly, as if some kind of switch had been touched.

Looking at Chaoyan jumping around like a happy groundhog, Lei Xiao's dark eyes lit up, and he suddenly realized: "I know, this magic circle is actually a pressure mechanism, and these metal plates are

A simple pressure sensor!”

"Pressure Sensor?"

Hearing this unfamiliar and modern word, the subordinates couldn't help but look at Lei Xiao with doubts on their faces.

"The thing is actually very simple. These metal plates sense our weight and then transmit it to the magic barrier below. The other party can sense our existence through this."

Lei Xiao first explained briefly and concisely, and finally concluded: "Because of this, those sleeping guardian puppets discovered us at the first time and were all awakened."

"So that's it! In other words, is this a special detection barrier that senses targets through weight changes on the ground?"

Ariel pondered for a moment, then nodded with enlightenment: "What a wonderful design. No matter how perfect the illusion, disguise, or other invisibility effects are, they can't hide their own weight!"

"No wonder the other party was able to detect our presence instantly. I didn't expect that this seemingly simple magic circle could achieve such a remarkable effect. This is completely different from the ordinary detection barrier."

Hongye, who had one hand on her hip, was surprised and couldn't help but exclaimed: "Which race is it that has such a unique idea?"

After Hong Ye finished speaking, other subordinates, including Jiang Li, also expressed surprise, apparently impressed by this special detection method.

"This unknown race is not only the builder of the Territory Guardian defense mechanism and the owner of the "Eternal Night Magic Box", but can also enter here without passing the "Key of Truth". It is indeed extraordinary.

He is indeed quite wise.”

A touch of curiosity and expectation appeared on Lei Xiao's face, and he looked at the silent abandoned town ahead.

"As long as we walk in there, we will get the truth immediately."
