Grandpa, I Don't Think I Can Keep Up the Act Much Longer

Chen Dong transmigrated to a parallel world. When he woke up, he found himself a 75-year-old man. Fortunately, he awakened the Invincible Old Man Level-Up System, which let him extract skills and item-crafting techniques, then upgrade them by spending achievement points.

"Grandson, your grandpa's getting on in years. I don't want to show off," Chen Dong said.

"Grandpa, that's easy. I'll do the showing off, and you handle the operation."

"Grandpa, I'm at the World Stock Market Gurus Summit right now, sharing stock-trading tips with a few big names. I'm kind of nervous."

"Grandpa, the head of Little Rice Country is begging me to let them buy a huge amount of the Great Desolation chips we make. Should I agree to sell them?"

Then one day...

"Grandpa, stop messing around with all these inventions! I'm having a hard time keeping up the act!"
