Taishang Laojun and Tathagata Buddha both felt somewhat helpless, but they still agreed to it.
They had to determine whether Uchiha Shin was real or fake.
For now, they only half believed that the Uchiha Shin before them was genuine.
If Uchiha Shin had entered some other place and then reappeared, they might have believed it. But entering a black hole and coming out alive was simply too hard for them to accept.
Taishang Laojun looked at Tathagata Buddha. "Venerable Tathagata, your Buddhist Sect's transformation techniques are among the best in the Three Realms. You should inspect him."
Tathagata Buddha nodded and stepped forward.
To put it plainly, transformation techniques were illusions and imitation arts. One had to become extremely similar to the object being imitated.
The Buddhist Sect's Puppet Technique could also be used in transformation arts, and it was exceptionally formidable.
For example, when Tathagata Buddha had previously used the Puppet Technique to transform into Uchiha Shin, even the Carefree Great Emperor had found it difficult to tell the difference.
Uchiha Shin stood there, calmly watching Tathagata Buddha.
Tathagata Buddha circled Uchiha Shin several times, continuously observing him through his Puppet Technique. At the same time, he heightened his senses to perceive Uchiha Shin's condition.
After the time it took to drink two cups of tea had passed, Tathagata Buddha stopped, turned toward Taishang Laojun, and lightly shook his head. He had not found anything either.
This surprised Taishang Laojun. "Let me take a look."
Taishang Laojun was the ancestor of the Dao Sect. If he used profound Daoist arts to inspect someone, any transformation technique would reveal its true form before his eyes. Not even the Buddhist Sect's Puppet Technique was an exception.
However, casting such a Daoist art would cause some commotion and take some time.
