West of the Crimson Nimbus Guild, where the Thunder Extinction Array was located.

The entire stone chamber was made up of dark gray magnetic ore. With the support of the array formation, it was possible to absorb the free thunder essence of the world no matter if it was day or night. If it was a thunderstorm, then the thunder and lightning would be directly sucked into the magnetic ore chamber to supplement the power of thunder.

At the entrance of the magnetic ore room, there was a Crimson Nimbus Martial School's deacon who was standing guard there. After Ling Yan went over to explain his purpose, the deacon took out a shiny crystal and placed it in front of Ling Yan.

The crystal shone with a misty white light, and Ling Yan only felt as if his body had been scanned. Then, to his surprise, a few lines of small characters appeared on the surface of the shining crystal: Ling Yan, 103rd place in the Thousand Army Array.

How amazing, Ling Yan thought to himself. There should be a special formation within this shiny crystal. It could directly obtain the student's ranking of the Thousand Military Array on the white altar, as well as record the student's usage time this month.

Formations were truly a miraculous thing.

After obtaining Ling Yan's identity, the Crimson Nimbus Martial School's deacon nodded and smiled: "Junior Apprentice Brother Ling Yan, authentication is qualified. Seeing that Junior Apprentice Brother Ling Yan is unfamiliar, I presume this is the first time you've come to the Thunder Ultimate Formation.

Ling Yan cheerfully nodded his head.

The moment someone enters, the magnetic chamber will automatically cut off the lightning supply and teleport you out. However, Junior Brother Ling Yan, it's best if you take the initiative to leave on your own when you can't hold on any longer.

After all, if it was passively transmitted out, the power of lightning would probably stay in your body for a short period of time when you were unconscious. This would slightly damage your body, and after you woke up, you would also need to spend additional time to repair the loss of your meridians.

He was not afraid of ten thousand. If the formation suddenly failed and he fainted in the magnetic darksteel chamber, he would be in grave danger.

"Within the magnetic darksteel chamber, you can choose your own thunder and lightning strength. Step by step, it's enough. Junior Brother, you can always stay within a formation. The moment you finish cultivating, you will be sent out by the formation."

Because the deacon was a student of the Crimson Nimbus Martial School who had graduated and stayed here to work, he was definitely older than the other students. In theory, calling a student a student of any subject a junior was not excessive at all.

"Okay, thank you senior brother, I understand." Ling Yan smiled and thanked him. Then, the Crimson Nimbus Martial School's deacon made a gesture to invite him in, and Ling Yan walked into the magnetic chamber.

After Ling Yan, Ling Yan, and Ling Yan entered the magnetic room, the Crimson Nimbus Martial School's deacon muttered to himself. This was strange; this name sounded so familiar, as if he had heard this name somewhere recently.

Aiyo, I … F * ck!

Suddenly, the Crimson Nimbus Martial School's deacon let out a cry of surprise. He suddenly turned his head and saw that Ling Yan was no longer there. However, there was still a trace of surprise in the eyes of the Crimson Nimbus Martial School's deacon.

"Now that I think about it, not long ago, Pang who was ranked 88 in the Thousand Military Array fought with a freshman. Didn't the news of him losing spread like wildfire? This freshman's name seems to be Ling Yan!"

The Crimson Nimbus Martial School's deacon's eyes went wide. Holy crap, I finally got to see the real body today. I didn't expect him to be so polite. This Junior Brother Ling Yan is pretty good. The Crimson Nimbus Martial School's deacon confidently nodded.

Upon entering, Ling Yan was surprised to discover that the large magnetic darksteel chamber was divided into ten smaller rooms, which meant that it could be used by all ten of the students at the same time.

If everyone was in the same magnetic chamber, it would inevitably be unable to meet everyone's needs. After all, dividing the ten would allow them to make the best use of the power of thunder to provide the best cultivation experience for the students of the Crimson Nimbus Martial School.

Ling Yan scanned the room and found that some of the doors of the ten small magnetic chambers were flashing with green lights, while some of them were flashing with red lights. He went up to push on the doors of the small magnetic chambers that were flashing with red lights.

Ling Yan guessed in his heart, and immediately verified his thoughts. He arrived in front of the small magnetic chamber with the flashing green light, placed his palm on the door, and with a slight push, the door opened.

As expected, the corners of Ling Yan's lips curled upwards as he entered the formation.

"Bam!" With a soft sound, the door to magnetic chamber eight closed tightly …
