Colt didn't do it now, staring at Tu San and puffing: "How can there be no water?!" You go and fight a stronghold, and then I know you're going to hit it, so I fill up the well, blow it up, resist for a while, and then retreat. You've taken my territory at this point, haven't you?! ”

Although Colt didn't understand what Tu Sancang was going to say, he still nodded.

Tu Sanpao touched the machine gun and continued: "I will surround you from the outside, and I will not beat you." But send someone to watch you, and if you want to move the machine gun, Lao Tzu will really shoot you. If you don't move, I'll harass you from time to time, and in short, don't let your gun rest. After a while, you won't even be able to eat water for three days at most, and the water of this gun will be useless! And you can't use this gun to charge all the way, if you want your people to charge in front, I'll hit you from the side! Even if I can't knock out your machine gun, I'll be able to destroy it! ”

Colt heard Tu Sancang's words, and he was speechless for a while. In the end, he could only say angrily: "Then according to your words, my gun will be useless?!" But our army is using it very well! ”

Tu Sanpao looked at the angry Colt and smiled, patted him on the shoulder and said, "I'm not saying that this gun is useless, but the usage is different." ”

"This gun~ The best place to use it is on the fixed position on the hill that the opponent must pass, let's dig a hole in the mountain first, take the ash and smear it so that the cannon can't come in, and leave a mouth to shoot. In the mountains! There must be a water source that we can bring over or dig a well directly in the hole, as long as there is a supply of bullets and food, and the place where the gun is set up is fine, then no one will want to attack it! ”

Tu Qianjun was dizzy when he heard his father's words, isn't this Nima a permanent fortification?! Dig tunnels to build permanent fortifications, then stock up on food and bullets inside, attract water sources, and block the enemy's offensive route with heavy firepower directly at the fixed fire points set up! Nima! Isn't this what is written in military textbooks?! Old man, that's a person who doesn't know a few big characters! Where did he learn this?!

And Zhang Xueliang nodded frequently after listening to Tu Sancang's analysis, now he can be regarded as convinced! Although these three artillery uncles have not read any books, their judgment and analysis of arms and weapons are extremely strong! It was only a moment before he judged the value of the machine gun and how it was used. At this time, he admired his father's vision even more, how did his own old man discover such a talent?!

After listening to Tu Sancang's words, Colt's face looked better, but then Tu Sancang picked up another M1921 Thompson submachine gun in the box, skillfully pressed the bullet and "da-da-da......" at the shooting range. But if the warlords are fighting, then Colt's business should be doing well! Why do you have to come to China to find food?!

But Tu Sanpao didn't think much about it, he felt that it was boring to think about these things. Clicked it directly, at this time, the sky was already dark, Tu Sanpao greeted everyone, and then pulled Colt back to the Marshal's Mansion together. Zhang Xueliang also returned to the Dashuai Mansion with a lot of thoughts, and in his opinion, today's harvest was discussed with his father.

If these weapons and equipment can be introduced into An**, then it will definitely have a lot of benefits for the improvement of An**'s combat effectiveness. So Zhang Xueliang planned to talk to his father that it would be best to introduce a production line. At the very least, it is necessary to ensure that the guns can be repaired and produced.

When he returned to the Marshal's Mansion, Zhang Zuolin had also come back and was talking and laughing with Yan Zhengqing in the living room. When they saw Tu Sanpao coming in, they greeted with a smile: "Sancang, I didn't expect your kid to know someone from the Colt family!" Awesome! I've been doing it for a few years, and your kid is a lot taller than me! ”

Tu Sanpao pursed his lips when he heard this: "Seventh brother, although I don't read any books, I still have the ability." Why can't you know this kid Colt?! Yan Zhengqing was brought to you by me! Why don't you say it! ”

After hearing Tu Sancang's words, everyone was stunned at first, and then laughed! At this time, Colt suddenly walked up to Yan Zhengqing and said very happily: "Ah~ It turned out to be Mr. Yan!" I remember you also visited our Colt factory! Do you remember me?! ”

Yan Zhengqing was stunned for a moment when he heard this, and then smiled as if he remembered something: "You are Phil, right?!" Hehe...... I remember you, you were the nephew of old Mr. Colt, and how old were you when I met you! I didn't expect it to be so big......"

Hearing Yan Zhengqing's words, Colt said excitedly: "Yes! Right! Right! That's me, I was young back then, but I still have some impressions of you. You and my uncle have been old friends for many years, but I don't know why I didn't go back to see him later. This has always been his regret. ”

Seeing that Colt actually knew Yan Zhengqing, Zhang Xueliang and his father glanced at each other and couldn't help nodding secretly. It seems that this Yan Zhengqing is really unfathomable, and he has visited Colt's factory and has something to do with the old Colt! For a while, Yan Zhengqing's figure cast a layer of fog in their hearts......
