Unfortunately, something unexpected will happen this year.

Yu Hua nodded in response and did not inform Zhao Zhongyao of the upcoming all-out war of resistance. Historically, due to the impact of the all-out war of resistance, Pingjin fell and North China was lost. The three northern and southern Qing schools evacuated Pingjin and concentrated in Changsha to build Changsha Provisional University, the predecessor of Southwest Associated University.

The exam for government-sponsored students studying in the United States with only 20 seats will definitely be affected by this catastrophe and will have to be postponed.

When exactly it will be held, Yu Hua doesn’t know.

However, he must take the exam for government-funded students studying in the United States with Geng Geng Grants. If he does not take it, he will not be able to study in the United States and lose the opportunity to make a fuss during the window period before the outbreak of World War II.

China has a window period before the outbreak of the Anti-Japanese War, and the entire world has a window period before the outbreak of World War II.

In Yu Hua's view, as a time traveler, we must not waste this opportunity to make a fuss.

Waste is equivalent to failure.——This is the basic quality that a qualified time traveler should possess.

"Yu Sheng, let's go to the laboratory and show you the true charm of nuclear physics." At this time, Zhao Zhongyao suddenly said before the get out of class ended.

Yu Hua was full of curiosity and nodded. There happened to be no classes in the afternoon, so he followed Zhao Zhongyao out of the classroom and headed to the most mysterious laboratory in Tsinghua University and even in the whole of China.

Zhao Zhongyao and Yu Hua walked through the Mechanical Hall and the Chemistry Hall and came to a small two-story red brick building. The plaque on the door clearly read - National Tsinghua University Nuclear Physics Laboratory.

Standing in front of the door, Zhao Zhongyao motioned for Yu Hua to come forward.

Yu Hua nodded, stepped forward with the key, unlocked the door, and pushed open the closed door of the laboratory building. The various cutting-edge equipment and instruments that existed in his imagination did not exist. The first floor of the laboratory building looked nothing like the teaching building.

the difference.

"Follow me." Zhao Zhongyao said to Yu Hua, walked into the experimental building first, and went straight inside.

Yu Hua followed suit and the two of them walked down the corridor. Soon after, they came to a closed door with information about Laboratory No. 1 written on the door.

Zhao Zhongyao took out a key from his body, unlocked it, and pushed the door open.

Yu Hua followed behind and walked into the laboratory with curiosity.

"This is an optical microscope."

"This is the Wilson Cloud Chamber, one of the main research instruments in nuclear physics. It is said that the California Institute of Technology has used an improved Wilson Cloud Chamber, and the improver is Teacher Millikan."

"This is an ionization chamber, which is also one of the main research equipment. It is very valuable. I brought it back from Caltech."

In the laboratory, the light is dim, and the windows are all covered with black curtains. It is surrounded by various experimental equipment and utensils. At the front is an optical microscope, and next to it is the famous Wilson Cloud Chamber. Professor Zhao Zhongyao introduced it to Yu Hua like a treasure trove.

Laboratory equipment.

Yu Hua was like Grandma Liu entering the Grand View Garden, curiously looking at these extremely primitive and crude equipment. It is hard to believe that it is through this experimental instrument that human physicists discovered and studied nuclear physics, mastered the planetary structure of atomic nuclei, and discovered radioactivity.

and rays.

magic.

It's really amazing.

At this time, Professor Zhao Zhongyao suddenly made a gesture to Yu Hua to follow him. Then, he walked towards the innermost part of the laboratory, came to a cabinet, squatted down, opened the cabinet, and carefully took out a wooden box.

Yu Hua stood behind him, his eyes staring at the wooden box, which was not that big. It was rectangular in shape and as big as a later Feitian Moutai box. Looking at Professor Zhao Zhongyao's solemn look, he felt a little expectant.

Under Yu Hua's gaze, Professor Zhao Zhongyao opened the lid of the wooden box, and in an instant, a faint blue light emerged.

Blu-ray!

An extremely pure blue light containing high energy.

A glass bottle containing 50 mg of radium was taken out by Professor Zhao Zhongyao with his bare hands and placed on the surface of the experimental bench.
Chapter completed!
