Zhao Hanzhang just casually sighed, but Fu Tinghan lowered his eyes and began to ponder, then said, "Generating electricity is not difficult. Not to mention that we currently have hydraulic facilities, we can also look for coal mines, or even use human power to generate electricity. The telegraph uses shortwave transmission, and since the ionosphere is very clean now, even though there are dense forests and a lot of water networks, I believe radio waves can be transmitted."
"The technical challenge lies in the vacuum tube, which I can't produce in a short time. I can only say I'll try my best. You might need to wait for quite a while."
Seeing him seriously analyzing the feasibility, Zhao Hanzhang was so surprised she opened her mouth wide, and it took her a while to find her voice again, "Then...then just give it a try."
