President of Datang [Transmigration Book]

Concubine Yang immediately liked the light bulb so much that she wanted to touch it.

Li Tan quickly stopped her and said, "Mother, be careful, this thing will burn if it burns for a long time."

Li Longji was quite interested, so he asked, "How is this... so bright?"

Li Tan thought for a while and narrated it in the simplest words, then looked at Li Longji full of expectation, and Li Longji also looked at him.

As soon as he saw Li Longji's slightly blank eyes, he knew... Come on, it's useless.

Fortunately, Li Longji didn't really want to study how this thing appeared, he just needed to know the result.

Concubine Yang Gui asked, "Does this lamp have other colors?"

Li Tan thought for a while and said, "It can have as many colors as the colored glaze has."

Concubine Yang was overjoyed, she turned to look at Li Longji and said, "Sanlang, it's better for our Qionglou Yuyu to use this lamp."

Li Longji nodded and said, "Okay!"

Li Tan's legs softened, and he almost knelt down to them: "Father, Auntie, this thing lasts for a cup of tea at most, and the carbon filament and battery need to be replaced, I'm afraid it won't work."

Li Longji waved his hand and said, "Aren't you still researching? Anyway, Qionglou Yuyu has not been built yet, maybe you will finish researching it when it is completed."

Li Tan: ...

He looked at the backs of these two people leaving in despair, and He Zhizhang next to him suddenly asked, "Is it fun?"

Li Tan said with a bitter face, "It's not fun."

It is not an exaggeration to say that there is a gap between the electric light and the normal use of the electric light. How can he make this development road go fast and steadily without making people feel abrupt?

For this, Li Tan kept flipping through the materials on the way back, but when he was approaching the palace, the carriage suddenly stopped.

Li Tan just wanted to ask, but in a daze, he saw a person rushing up quickly.

Before he could see the person who came, a dagger was pressed against his throat, and the person said in a low voice, "Thank you brother, please help me."

Li Tan: He Zhizhang... probably won't let me teach anymore...
