After entering the secret chamber, the old man turned to look at the three of them. "The three of you need..."
Before he could utter the word "intelligence," the old man froze on the spot. His gaze fell on Lin Chuan's face—or, more precisely, on his eyes. Within those blood-red pupils, a windmill-like pattern slowly turned. The instant he saw those eyes, the old man's consciousness completely fell under their sway.
This old man was at the Great Perfection of the Integration Stage, and his spiritual cultivation was not particularly high. Faced with Lin Chuan's genjutsu, he had no way to resist and fell straight into it.
Maintaining Kotoamatsukami in his left eye, Lin Chuan switched his right eye to the Eight-Tomoe Rinnegan. He extended his right hand and pressed it against the old man's head.
"Mind Layer Submersion."
The fastest way to obtain intelligence was to directly read memories. The memories of these intelligence agents were naturally Lin Chuan's first choice. They could give him an extremely detailed understanding of the Longevity Realm and were far more valuable than the memories of the cultivator he had read earlier.
"There's even a secret technique to prevent soul searching. Unfortunately, it can't stop my Mind Layer Submersion!"
Lin Chuan murmured softly.
These intelligence agents knew too much, making them easy targets for those with ulterior motives. Placing seals within their memories protected both themselves and the intelligence they possessed.
However, such measures were useless before Lin Chuan. The Rinnegan's Dojutsu was not so easily countered, and Lin Chuan possessed two great Primordial Scriptures. Even seals placed by the Supreme One Clan could be broken by him.
Perhaps the old man's rank was not high enough, though, because his memories contained no seals left behind by the Supreme One Clan—only ordinary measures
