The restricted area behind the Hokage Building was heavily guarded.
Qian Ye passed through two corridors of Chakra barriers and arrived before a heavy black iron door.
Two ANBU ninja wearing animal masks stood before the door, hands resting on the swords at their waists.
"Stop. Password."
The ANBU on the right spoke coldly.
Qian Ye did not waste words. He took out the specially approved authorization from his robes and handed it over.
The ANBU accepted the order and carefully inspected the Hokage's seal and Danzo's private seal upon it.
After confirming that everything was in order, the ANBU's attitude softened considerably.
"Chunin Qian Ye, you have two hours to read on the third level."
"You should know the rules. No paper or pens may be brought inside, and copying ninjutsu is strictly forbidden."
"The Barrier Team monitors Chakra flow twenty-four hours a day. Any violation will cause the barrier to seal automatically."
Qian Ye spread his arms and allowed the other man to scan him from head to toe with a sensory ninjutsu.
"Relax. I'm a law-abiding, good ninja."
"I didn't even bring an Explosive Tag. Just these two eyes."
After finishing the inspection, the ANBU nodded and turned to pour Chakra into the black iron door.

This was the core foundation Hidden Leaf had accumulated
