Zhang Yu replied calmly, "Then who is the master behind you, sir?"
The middle-aged man straightened up. Even under such circumstances, he revealed not the slightest hint. "That is not something Mr. Tao can ask about at present.
"When the time is right, we will naturally tell you. His status is even more noble than Protector Zhu's. If Mr. Tao is willing, you will not regret your choice."
He extended a hand, and the woman beside him passed him a document. He placed it before Zhang Yu.
"I recall that Mr. Tao has yet to sign a document of allegiance with Protector Zhu, correct? If Mr. Tao is willing to sign this document, then we will be colleagues."
Yet Zhang Yu remained expressionless and made no move.
The middle-aged man smiled and said to the woman beside him, "It is all right. We can give Mr. Tao some time to consider. There is still some distance before we reach our destination." He then looked at Zhang Yu, wearing the air of one who held the overall situation in his grasp. "Mr. Tao need only give us his answer before we disembark from the flying vessel."
He took two steps away, then seemed to recall something and turned back. "Oh, right. We know that Mr. Tao is a cultivator, but do not entertain any wild thoughts, nor do anything futile."
As he spoke, the crystal doors on either side of the flying vessel flashed. Six Creation refiners entered from a side compartment. They were the vessel's guards.
Zhang Yu glanced at them. He had sensed Creation refiners appearing around him before, but this was the first time he had truly seen them.
Judging by the spiritual power upon these six, they were roughly at the level of Primordial Spirit Shadow Reflection.
