After passing through the back door of the cafeteria, Lei Yuan coughed loudly.

The sound was like a mud cow entering the sea, and there was no expected barking of the dog.

Lei Yuan speeded up his pace. As soon as he walked around the back wall, he heard a panic sound and shouted: "Old Li, come and see, what's wrong with our Dahuang?"

Lei Yuan's mood suddenly became heavier, and a bad feeling arose.

When he arrived at the kitchen door, he saw an old man in a white dress running out of the house, a middle-aged man in a white dress squatting on the ground. Next to him was the big yellow dog, who had collapsed to the ground and foamed at the mouth. The old man in a white dress immediately leaned over to observe, picked up the dog with both hands, and tried to help it up, but the big yellow dog just couldn't stand up.

"I just saw it was still elves, why did it look like a bear in a while?"

As soon as the old man finished speaking, the yellow dog in his hand suddenly jumped up, broke free from his hands, jumped for a few moments, and soon his legs became weak, and then his body began to twitch, and he rolled on the ground with heavy breaths, looking extremely manic.

The two canteen chefs were startled and quickly took a few steps back.

Lei Yuan walked up, squeezed forward and took a look, and said, "This dog seems to be poisoned?"

"Who are you? What are you doing here?" the middle-aged kid asked anxiously, and looked at Lei Yuan with a vigilant look.

Lei Yuan said calmly: "I drank high last night and my head still hurts. I want to ask for some salt and use salt to dissolve the wine."

The old man said, "No, we are in the kitchen, how could we get poisoned?"

"Maybe I ate something unclean..." Lei Yuan said lightly, suddenly remembering an important link, and quickly added, "Anyway, this dog will definitely not be able to eat even if it dies!"

"Why?" the two men asked in unison.

"What if someone poisons?"

"Ah?" The two guys immediately stared at him with wide eyes.

Lei Yuan shrugged and responded lightly: "When is the time now? The Japanese are about to attack Nanjing! Where are we? Central Military Academy! It is not guaranteed that the Japanese spies have already sneaked in. Maybe they are carrying out any conspiracy. You'd better report to the top and ask someone to check what poison is in this dog, so you know it."

"Yes..." The middle-aged man glanced at the military rank epaulette on Lei Yuan's shoulder, "What the little commander said is!"

After saying that, the middle-aged man walked into the kitchen room, wrapped a small bag of coarse salt grains in paper, and handed it to Lei Yuan and asked curiously: "This is the first time I have heard of salt water lying wine..."

"Of course! Don't underestimate this salt. If you have too many functions, salt water can also reduce inflammation!" After saying that, he put the salt bag in his top pocket and walked out of the kitchen slowly.

Along the way, Lei Yuan was in a very uneasy mood.

Now, he could roughly make a judgment that Guo Donglai poisoned the cup of water that the host was drinking.

Judging from the symptoms of dog poisoning, it is very toxic, and the poison is very similar to arsenic trioxide, which is arsenic.

Although Lei Yuan was just a graduate of a third-rate university in his previous life, it does not mean that he is not outstanding enough. The biggest reason is that his learning attitude is not very good and his family conditions are very bad, so he missed many opportunities.

In his third year of high school, his laid-off father was in a bad mood. He was drunk every day and was depressed. He finally encountered a tragic car accident in the chaos and passed away. His mother could not withstand such a huge blow and could not afford to be ill. He passed away in his sophomore year. Lei Yuan barely finished college with the meager funding of his grandparents in the countryside.

But Lei Yuan's talent is still remembered.

He studied science and engineering, had been exposed to chemistry tutorials, and knew the symptoms of arsenic poisoning. The most obvious characteristics are breathing difficulties, irritability, and agitation...

But why did Guo Donglai take this harsh action?

Is it just because he also deeply likes You Qingman?

With such questions, Lei Yuan came to the instructor's office.

Yue Weiwu was already waiting as scheduled.

Lei Yuan said timidly: "Instructor Yue, I'm here."

Yue Weiwu looked at Lei Yuan, pulled out a chair to attract Lei Yuan to his seat, and then said, "Lei Yuan, what's wrong with you today? It seems like you have changed someone?"

Lei Yuan deliberately yawned and pretended to be listless and replied, "I got drunk last night and I can't recover until now." After saying that, he suddenly sat upright and cheered up, "Instructor Yue, tell you something. When I went to the canteen kitchen just now, I saw that the big yellow dog was about to die, and it seemed that someone had been poisoned..."

"Hmm?" Yue Weiwu was stunned.

"I guess it's arsenic poisoning."

"What?" Yue Weiwu was shocked and sat up straight, "poisoning a dog with arsenic? Why?"

"I don't know this, but you can ask someone to check it out. If it is really arsenic, you can trace its source."

"Okay, I will make arrangements!" After saying that, Yue Weiwu walked out with a solemn look on his face, came to the office next door, and immediately explained to the person.

When he returned to the room again, Yue Weiwu looked much more relaxed and said to Lei Yuan with a smile: "Your elder brother, Brigade Commander Zhu, called you just now and asked you to go to the Lanwan Teahouse in Gulou at noon. He had something to remind you... By the way, he also said that if it is convenient, it is best to call Shangyou Qingman."

"How did he know You Qingman?" Lei Yuan was very surprised.

Yue Weiwu smiled and did not answer. He took out a pack of Zijinshan cigarettes from his arms, handed them to Lei Yuan, took out another one and bit it on his mouth, and lit it for Lei Yuan and himself with a lighter, and his face slowly became solemn:

"Lei Yuan, I'll make you a request..."

"Please speak instructor."

Yue Weiwu stared at Lei Yuan without turning his eyes and said in a deep voice: "As far as I know, in this Nanjing defense battle, the First Brigade of your teaching corps is responsible for the blocking position outside Zhongshan Gate, and the Second Regiment where you are located was deployed on the Nankuo position in Zijin Mountain. I analyzed that the biggest possibility of the Japanese attack on Nanjing is to arrange heavy troops from Yuhuatai outside Zhonghua Gate and Zijin Mountain outside Zhongshan Gate to tear open our defense line. Therefore, the pressure of your first brigade can be imagined, especially the Nankuo position in your second regiment is the top priority. Therefore, the battle between the two sides must be extremely fierce. I ask you to do everything possible to survive!"

Speaking of this, Yue Weiwu took a deep breath of cigarette, took it off and clamped it between his fingers, staring at Lei Yuan tightly.

Lei Yuan was moved, thought for a moment, and nodded firmly.

As a large mouthful of smoke rose, Yue Weiwu nodded with satisfaction and said, "You Lei Yuan is one of the most outstanding students in my career as an instructor. If you die for the country, I will be extremely heartbroken. For public and private, I think you can bear great responsibility! As long as you are alive, my promise to you remains unchanged, and our revival society has an important position for you. Of course, I know that your ambition is not here, but I can tell you that the Blue Clothes Society is personally led by our principal. The moon is the first to be close to the water, and the day is just around the corner. It is better than being in the army for three or five years and still being a grassroots officer..."

Lei Yuan refused to comment and changed the subject: "Instructor, what would I do if I am still alive in this fierce battle?"

"Hard with dormant, I will wake you up with my own way!"

Lei Yuan nodded again.

Yue Weiwu stood up, pinched half of the cigarette in the ashtray, held Lei Yuan's hand, and said solemnly: "Your code name in the Blue Clothes Club is still the same. I have received an order. I will take a boat up the river tomorrow and rush to Chongqing to preside over the work of the Blue Clothes Club. Take care of yourself!"

"Yes!" Lei Yuan also stood up.

Yue Weiwu personally sent Lei Yuan to the door. Lei Yuan remembered something and seemed to be nothing and asked: "By the way, instructor, do you know what Guo Donglai has assigned?"

Yue Weiwu smiled and said, "This matter is not a secret to you. He will move forward with me tomorrow. Why? He doesn't want to tell everyone?"

Lei Yuan also laughed: "This kid is mysterious!"

"No wonder Guo Donglai is very angry. Among the students in this period, he is the best except you. You cover him everywhere, and he feels angry and always compares you!"

Hearing this, Lei Yuan immediately straightened his body, saluted Yue Weiwu, and left with great strides.

Originally, he wanted to say something about Guo Donglai, but now he is even more reluctant to say it.

Besides, the evidence is insufficient, and he is another reborn person, where can I start?
