What is this technique?

It seems like he had somehow encountered a sentient artifact everything made sense now. How his body recovered so fast and became stronger, even the voice. It's a sentient artifact. But he still had no idea how he got into contact with the artifact. He's sure that he had somehow had an encounter with a sentient artifact after he blacked out until he got home. He would have to investigate it. He had never thought to investigate how he got home that day, since truly it didn't matter to him, but now he had to find out.

Wang Ming contemplated about telling his Shifu about the sentient artifact. "Shifu, how rare are artifacts and rare artifacts?" Jie scrunched his eyes like he was calculating the numbers after 10 seconds he answered Wang Ming.
