The bronze battle chariot could act as an offensive means and crush everything around it. It could also act defensively and seal its surroundings. Furthermore, he could simply use it as a means of transport to vanish without a trace.
Although the bronze chariot wasn't a top-level treasure, it should at least be a Taishi treasure based on the fact that it was in Tianzi Treasure Vault.
A single Taishi Treasure that encompassed both offensive and defensive means could improve Luo Yunyang's strength significantly.
However, his thumping heart made him put down the battle chariot, which he had been about to select. Although he did not know why his heart thumped harder than usual, he knew that the item that had caused him to feel such a sensation had to be extraordinary.
By following his intuition, he took a couple of steps and approached a simple rack made of stone.
The rack was very plain, and four or five inconspicuous wings were resting on it.
