They had discussed it with Jiang Yan Hai back home. If another stargate opened here—and that was very likely—there was no reason for the other side to have a self-destruct device while this side did not.
If another stargate opened and led to the same world as the one Jiang Yan Hai and the others currently controlled, then their mission would be to get involved and make it easier for the homeland to negotiate with the Americans.
To put it bluntly, even with just one stargate, there was no way the homeland could monopolize it alone. Nor could it monopolize it together with the Republic of Goa.
It was simple. Your naval power was insufficient. While the neighboring country did not dare start a war with you, it could still make things unpleasant for you. And knowing its style, if it could not have it, do you believe it would not find a way to destroy it?
That situation did not serve the homeland's interests, because the benefits offered by this new world were not actually that great. Its technological level was comparable to theirs, which meant they could at most conduct trade with the other side.
And how much money could trade make? At most, they could exchange metal ores that were scarce to either side.
But the homeland was different! Do not forget that it had the Great Qin world.
To put it plainly, this newly discovered world would directly draw the Americans' attention away. Then the homeland could quietly make a fortune through Great Qin. In addition, during negotiations, the Americans would inevitably be made to open their market.
As long as the trade market opened, Chinese products would swiftly capture their market, quietly taking the initiative.
Quietly making a fortune was the true path to greatness.
