The figure of Iwa Ninja Village quickly passed through his eyes. The white teeth in the cave's eyes condensed slightly, his heart was as calm as water, and the chakra flow in his body dropped to a minimum. Even if it was a perception ninja, as long as it was not close to a certain distance, he could not feel him.

The ninjas of Iwa Ninja Village searched the area, but found no trace. They were clearly sure that they were close behind White Teeth.

After a long time of unwilling search, they had to helplessly admit that Baiya might have escaped with some unknown method and could only retreat unwillingly.

After they evacuated, Baiya did not go out directly, but waited patiently for a day, spending only the dry food they carried with them in the cave.

He was not relieved until he was really sure that the other party had really left.

...

"But what happened to this cave?" Baiya did not go out, but looked at the cave where he was now in detail.

This time he was able to escape from danger, this cave is the first achievement. It was also what he discovered when he was escaping by chance. The entrance of the cave was covered by nearly perfect illusions. If he had not entered it by mistake, he would not have entered it. Therefore, no matter how much the people in Iwa Ninja Village searched, they could not find his figure.

But the question is here, why is a cave on the border between the Kingdom of Grass and Kingdom of Fire hidden by this exquisite illusion? This could never have been formed naturally.

With a strong curiosity, Baiya ate something to recover his energy, and then slowly walked towards the inside of the cave.

Before, because of the Iwa Ninja hunting for ninjas, he never left the cave entrance. If the Iwa Ninjas people really discovered this place, they could take the opportunity to attack them to create chaos to get out of trouble.

The cave is dark, and water droplets drip along the rock walls, making a slight sound, everything looks no different from ordinary caves.

Under Baiya's footsteps, he quickly came to the inside of the cave. There was no light here, quiet and dark, and the rock walls were filled with coldness. There was nothing except Baiya who had just arrived.

"Hmm?" Baiya frowned gently, took out a tiny torch from the ninja bag behind her, and waved the torch in the wind, bringing a long-lost light to this cave.

"How come there is nothing?" Baiya asked in confusion and began to search inside the cave.

Most ninjas are very patient, and he is one of the best. He checks every rock inside the cave with a torch. He vows to find out the difference here. The illusion at the entrance of the cave will never be formed naturally. Even if someone hides something here, at least something must be needed.

"Here?" Suddenly, Baiya's hand paused. When he was checking a rock wall on the side, he found something wrong. There was a very slight chakra flow in this rock wall.

This flow is extremely weak and may be ignored if it is replaced by others, but Baiya has performed countless tasks and will not let go of any subtle points.

If you look closely at this rock wall, there is nothing special except the chakra flow that seems to be an illusion of one's own.

"It looks like some special sealing technique, huh..." Baiya pondered a little, recalling everything about the sealing technique in her memory.

"It seems that I have seen records of this sealing technique in the Anbu archives. Is it some ancient technique of the Uzumaki clan?"

He frowned and began to seal according to his memories, "I remember the seals recorded at that time were like this, and then according to the characteristics of the sealing technique of the vortex clan, he tied all the seals upside down, and then!"

"Seal, open!"

With a light shout, the chakra in the palm of his hand covered the rock wall. Suddenly, the stone wall made a slight rumble, opening like a door.

"It's actually a secret door?" A strong white light appeared from the rock wall. Baiya subconsciously closed her eyes and opened it for a moment.

Looking at the steps below, he stepped in without hesitation. In an instant, he only felt a bright light before his eyes, as if he had arrived at an underground kingdom. The spacious, bright and well-connected steel roads and complex buildings all appeared. The bright white light spread on the surrounding walls, illuminating the entire underground kingdom like daytime.

Baiya widened her eyes, looked at everything in front of her in disbelief, and her mouth opened even more unconsciously.

He was born in Konoha Anbu and had completed many tasks. He was the highest person in charge of the third generation of Naruto and the third generation of Naruto. He was naturally extremely familiar with the Anbu base under Konoha. But compared with this place, it suddenly became a dark country base, which was not comparable at all.

"In the ninja world, there are organizations of this size hidden!" Subconsciously amaze, Baiya's eyes quickly scanned, and the light almost illuminated every corner, making it difficult to hide effectively.

However, there seemed to be not many people here. He had not seen anyone after entering for so long.

"We must find out the details here." He made up his mind and instantly turned into a black shadow and headed far away. His hands instantly formed seals, "Secret Technique, Secret Technique!"

Resting against the white steel wall, the color of his body suddenly turned white, consistent with the colors around him, just like a chameleon, and he could not detect it without getting closer and closer.

...

Step, step...

The sound of footsteps rang in the aisle, and two medical ninjas in white coats walked slowly by. One of them was holding a white medical box in his hand, which contained a test tube, and the green liquid body was shaking.

"This time Lord Xing Ruyu came here to personally inspect the development of the No. 5 potion. Most of the main R&D personnel have been summoned to report the situation, so we will take the sample over as soon as possible." The medical ninja on the left spoke.

At this moment, a figure appeared silently behind them. The short blade with a cold light suddenly took action, and the medical ninja who had just spoken fell silently.

"Who?"

"Don't move!"

Another ninja reacted instantly, but only felt his hands soft and he had been captured by a force. He was carrying both hands, and the short blade had touched his neck.

Bang!

The medical box in his hand fell to the ground, the test tube in it broke, and the green liquid spilled all over the floor.
