Zhang Chengchuan and Lu Zhanguo took a look and found that there was nothing but firewood. When the firewood was almost harvested, the rain finally fell, and from the first few drops of rain quickly turned into a rain curtain.

The heavy rain in summer is very heavy and it is very powerful when it hits. It can make a loud noise when it drips on the ground, and it will feel pain when it drips on people.

Zhang Chengchuan and the others quickly put the firewood on and quickly covered the oil cloth. Their movements were a little slower. Some of the firewood at the bottom were wet, but they were not much wet, and the small area was a little wet.

"This rain came too fast." Zhang Chengchuan couldn't help but sigh as he looked at the rain curtain that quickly turned from the first few drops of rain to heavy rain.

"You want to go back next door or stay here now? When I'm doing research, you can help me." Zhang Chengchuan asked.

Zhang Chengchuan not only treated Lu Zhanguo and other soldiers as his bodyguards, but also needed them to be assistants when doing experiments.

Why did he persist in teaching his soldiers every day? It was not just to give them more survival rates when they were in the wild, not just to allow them to go further, but also to help someone help him while he was doing experiments.

Lu Zhanguo was a man who studied very seriously and made rapid progress. His family was not much, but it was not very bad. Lu Zhanguo had also studied in military academy because of his outstanding performance, but in a few years.

It is also very good for Lu Zhanguo to be able to learn these things from Zhang Chengchuan. If he did not sacrifice his misfortune when he was on mission in the future but was unfortunately injured and could not continue to train in high-intensity, he could also rely on the various knowledge learned from Zhang Chengchuan to make a special trip to the technical soldiers.

Therefore, Lu Zhanguo studied very seriously. He made rapid progress and was the one who followed Zhang Chengchuan to do research as his assistant.

Lu Zhanguo did not refuse, but followed Zhang Chengchuan to do the experiment.

When doing solar energy research, we have to figure out how to convert solar energy into electricity. Zhang Chengchuan also has to figure out how to make circuits and what kind of materials can be cheaper and have very good results.

Zhang Chengchuan now has ideas, but he has not yet had a definite research direction and has too many things to learn, so the research progress has slowed down.

But he is not in a hurry at all. The things others have studied may not be able to produce results in several years. He does not need to be so anxious. It is better to enrich himself more.

Chen Xiayue watched them get to the forging room again and continue to do research, but she didn't care about it. Seeing the heavy rain outside and the flowers and plants she raised were falling in the wind and rain, she didn't dare to go out and give her in-laws raincoats or something.

Because it was raining, Chen Xiayue specially chose two sets of raincoats with thicker materials similar to oil cloth for her in-laws, treating them as something she bought for her in-laws with her parents-in-law.

After having the raincoat, Zhang Deping and Liu Guiying were less wet from the rain, but sometimes the sun was very strong in the morning, but it suddenly rained heavily in the afternoon, so they would also get wet from the rain.
