Even if he went back, he could still give a proper report—these biologically engineered human tribes are far from the Eastern Human World and close to the Western Human World, so Malin stepping forward to teach them wouldn't be considered crossing any lines in the eyes of the Thanans.
Thus, Malin could completely bypass the Thanans, so ultimately, it didn't matter.
This made Malin very happy. Reaching an agreement with the Thanans on this matter, he even went out of his way to provide the Thanan ambassador with some new blueprints. The ambassador, having obtained the blueprints, didn't mind at all—after all, even if they couldn't buy metals here at a bargain price, the Thanans believed they had already profited. In their view, it was better to sign a fair commercial contract now than to risk these biologically engineered humans cutting off trade due to resentment toward them.
This left Malin deeply admiring the ambassador's conduct—what a flexible and pragmatic old gentleman.
