1. First, it is necessary to build an interstellar energy generator, which can be made of interstellar energy minerals and other needed materials.
2. Secondly, put the interstellar energy generator in a suitable position, close to the iron gate to be connected. Make sure that the generator can be located near the iron gate.
3. Finally, connect the star energy transmitter, and connect the star energy generator with the iron gate with the star energy transmitter. The interstellar energy transmitter is a special box that can transmit interstellar energy.
