"Director Jiang! You are welcome to visit us at the rolling mill!" The group walked into Director Yang's office, and when Director Yang saw Director Jiang and Wu Aiguo and others, he immediately came forward and greeted everyone warmly.

Director Jiang shook hands with Director Yang, and introduced to Director Yang with a smile, "Director Yang! Let me introduce you to you, this is the deputy chief of the procurement department of our supply and marketing cooperative, Wu Aiguo pushed!"

When Director Yang heard Director Jiang's introduction, he said to Wu Aiguo with a grateful face: "Comrade Wu Aiguo! Without your help this time, the goods shipped to Baoding by our rolling mill are likely to be robbed by the enemy, and on behalf of our rolling mill, thank you for your help."

When Wu Aiguo heard Director Yang's thanks, he first shook hands with Director Yang, and then replied modestly, "Director Yang! As a former Chinese soldier, it is our duty to fight the enemy."

When Director Yang heard Wu Aiguo's words, he shook hands with Director Xiao, and then greeted everyone, "Director Jiang! Director Xiao! Patriotic comrades! You may be seated."

Wu Aiguo heard Director Yang's greeting, thought of the scene he had just seen, and immediately said to Director Yang, "Director Yang! On the way to your office, we saw several Dongying people standing in front of a pile of slag, and I heard Captain Huang say that this group of Dongying people plan to use foreign exchange to buy the slag from your factory, is this true?"

When Director Yang heard Wu Aiguo suddenly ask about the purchase of slag by the Dongying people, there was an unexpected expression on his face, and he replied with a smile: "Patriotic comrade! There is indeed such a thing, but our superiors believe that the Dongying people are unprofitable, and they are willing to buy our slag with foreign exchange, and there must be some conspiracy hidden in this, so we should be cautious."

Wu Aiguo heard the introduction of Director Yang, thought of the fact that Dongying people went to Huaxia to buy slag in the seventies, and replied with a smile: "Director Yang! You're right, the people of Dongying are indeed unprofitable, because this slag contains very important minerals."

"Patriotic comrade! What did you say? This batch of slag in our factory contains very important minerals, who did you listen to about this?" When Director Yang heard the news that Wu Aiguo told him, an extremely shocked expression appeared on his face, and he hurriedly confirmed the news to Wu Aiguo. Chinese Net

Wu Aiguo heard Director Yang's inquiry, saw the shocked expressions of Director Yang and Director Jiang and others, nodded very affirmatively, and replied, "Director Yang! If the ore used in your factory is transported from Baotou, then this batch of slag contains very rare minerals."

When Director Yang heard Wu Aiguo's answer, a puzzled expression appeared on his face, and he said to Wu Aiguo: "Patriotic comrade! When the Dongying people proposed to us to buy our slag with foreign exchange, the leaders of the ministry felt that there must be a demon when something went wrong."

"Because I felt strange, the ministry asked researchers from the Chinese Academy of Sciences and the Institute of Mining and Metallurgy to analyze the slag in our factory, and the results did not find any differences in these slags? How do you know that this rare mineral is contained in these slags?"

Wu Aiguo heard the situation introduced by Director Yang, and asked Director Yang with a smile, "Director Yang! Since you all think that there is nothing in these slags, why would the Dongying people pay for it, are the Dongying people stupid?"

When Director Yang heard Wu Aiguo's words, he agreed with what Wu Aiguo said, and replied with a smile: "Patriotic comrade! Your thoughts, and ours, all coincide! Therefore, the ministry will definitely seal this batch of slag temporarily, but the Dongying people have proposed to exchange the slag with us in the same weight as grain, and the ministry is now studying the exchange with the Dongying people."

"Director Yang! Whether it is sold or exchanged, these slags must not be given to the people of Dongying." When Wu Aiguo heard the situation introduced by Director Yang, he immediately realized that his superiors were likely to exchange slag for grain with Dongying people because of the lack of food, and hurriedly expressed his meaning to Director Yang.

When Director Yang saw Wu Aiguo's reaction, he faintly felt that Wu Aiguo must know the value of this batch of slag, and hurriedly asked Wu Aiguo tentatively, "Comrade Patriot! Do you know the secrets of this batch of slag?"

Wu Aiguo heard the introduction of Director Yang, the secret of the Dongying people's purchase of slag, and the scientific research department of Huaxia only succeeded in solving the puzzle in the 80s

Things made him immediately realize that he was too impulsive.

Thinking that this batch of slag contained precious metals, Wu Aiguo immediately remembered his comrade-in-arms who had already died, and hurriedly introduced, "Director Yang! Here's how it happened, when I first entered the rolling mill, I saw a group of people in suits chatting in front of the slag pile."

"So I curiously asked Captain Huang about the identities of these people, and Captain Huang told me that those people were from Dongying, and that the people from Dongying wanted to use foreign exchange to buy these slags from your rolling mill."

"Knowing this situation, I feel puzzled, Dongying has not established diplomatic relations with our country, why did these Dongying people come to the rolling mill and buy these slags with foreign exchange?"

"Because of this doubt, I suddenly remembered one of my comrades-in-arms, so I asked Captain Huang a lot, is the ore used in your rolling mill transported from Baotou? As a result, Captain Huang's reaction proved my guess in disguise."

Wu Aiguo's introduction made Director Yang feel even more puzzled, and asked Wu Aiguo curiously: "Patriotic comrade! How can you guess that the iron ore from our factory was shipped back from Baotou? Do you know the secret of this slag?"

Wu Aiguo heard Director Yang's inquiry, and introduced with a stern face: "Director Yang! I'll tell you the truth! One of my comrades-in-arms, he is from Baotou, when the war broke out, his grandfather and father were captured by the Dongying people and sent to the mines of Wuyuan City to mine."

"As a result, by a very coincidental circumstance, I heard from the interpreter of the mine that there was a very precious metal in the mine, known as industrial gold, and it was also a key material used in the production of tanks and airplanes."

"Patriotic comrade! Are you sure that the metal contained in the ore in Baotou is a key material for the production of tanks and aircraft?" When Director Yang heard Wu Aiguo's introduction, he immediately couldn't sit still, and hurriedly confirmed the news to Wu Aiguo.

Wu Aiguo heard Director Yang's inquiry, saw Director Yang's excited expression, subconsciously shook his head, and replied, "Director Yang! I also listened to my comrades-in-arms about this matter, and I am not sure if it is specific."

"As for why I guessed the source of the ore from the rolling mill, it was because these Dongying people were willing to use foreign exchange to buy our useless slag, which reminded me of what that comrade-in-arms once said."

"Patriotic comrade! Where is that comrade-in-arms of yours now?" When Director Yang heard Wu Aiguo mention his comrade-in-arms, he immediately realized that Wu Aiguo's comrade-in-arms must know more about the situation, and hurriedly asked Wu Aiguo.
