After The Scientific Research Boss Dressed Up as a Pitiful Little Guy [QT]

3.33 - Birthday

　　Chu Chengwaner: "This is a good idea."

　　Two years later, he had already invented a timed bomb. As long as he knew the wind speed and direction and calculated the time, he could send it to the palace to detonate and kill all the eyesores. Of course, innocent eunuchs and maidens would also be accidentally injured. And instead of airdropping it, it would be more convenient and faster for the spy to send it directly to the emperor's palace.

　　Chu Cheng had no intention of solving the problem so roughly.

　　"But I am planning to use a hot air balloon to throw dry ice to achieve artificial precipitation."

　　Modern artificial precipitation uses aircraft. But due to limited technology in ancient times, he had no choice but to settle for a hot air balloon.

　　As soon as he finished speaking, Ning Zhili was shocked, and a pair of eyes suddenly burst into scorching light: "Artificial precipitation?!"

　　"Does Mr. Ning still remember the physics knowledge in the textbook?"

　　"Of course! Dry ice is solid carbon dioxide. When heated, it absorbs heat and turns into a liquid state!" Ning Zhili opened his mouth with a photographic memory.

　　Chu Cheng couldn't help but nodded, and added: "Dry ice enters the clouds, and after absorbing heat, the temperature of the clouds will drop sharply, causing the water vapor in the atmosphere to condense into small ice crystals, and then use the small ice crystals as condensation nuclei to continue to condense into water droplets, which fall to Ground."*(1)

　　Ning Zhili understood, and precisely because he understood, his breathing became rapid: "If we can succeed, Daqi will never have to suffer from drought again! The merits of the empress will last forever!"

　　What made him even more emotional was that putting gunpowder in a hot air balloon would be a murder weapon; putting dry ice in it would be a life-saving weapon!

　　One thought kills, one thought saves, it all depends on the user's attitude!

　　Thinking about it, he immediately patted his chest and promised: "Don't worry, Madam, I will go back and lead those boys to work overtime to make the hot air balloon!"

　　"Then it will be troublesome for Mr. Ning."

　　Ten days later.

　　On this day, the weather was surprisingly good, and it seemed that God was also celebrating Chu Cheng's birthday.

　　The Prince of Nanyue set up flowing banquets in various squares in the city and invited people to eat for free to celebrate the princess's Double Tenth birthday; major stores in the city also used this as an excuse to sell products at discounts; a cheerful lion dance team ran through this street Going to that street attracted the laughter of children.

　　Many people got up early in the morning, hung festive red lanterns at the door of their homes, and then delivered the gifts they prepared to the door of the Nanyue Palace. They were not afraid of the guards at the door and left after delivering the things.

　　The palace guards did not stop him, but happily put the gifts he selected into the gift pile.

　　So when night fell, when various forces arrived at the palace, they saw that the stone lions at the door were already covered with various gifts, which looked very festive.

　　"What the people want..."

　　Jiang Weixian stroked his beard with a look of emotion on his face.
