[Electromagnetic propulsion control technology, 1 million experience value points. This technology includes the electromagnetic generator, the electromagnetic propulsion controller blueprint.]
[Electromagnetic stealth technology, 1 million experience value points.]
[Ultra long distance communication control technique, 1 million experience value points.]
[Small planet magnetic plane blueprint, 1 million experience value points. The prerequisite technology is electromagnetic dynamics control technology.]
In the end, four technologies were left in front of Li Chengqian.
Li Chengqian opened the introduction of the small planet magnetic plane blueprint.
