At this time, Yan Zhengqing also came back, and when he heard Colt say that he wanted to make a lot of money, he couldn't help but be a little surprised: "Phil, what is it that wants to make a lot of money?" Although this student has a lot of things to hide from himself, he is sure to be diligent and studious. And it's respectful enough to yourself.

After Yan Zhengqing motioned for Tu Qianjun to sit down, he smiled and said to Colt: "What kind of thing makes you so excited?!" Do you have a crush on the arms market again?! ”

Colt saw that Yan Zhengqing was back, and quickly sat down next to Yan Zhengqing and said energetically: "Oh! Mr. Yan, you don't know what kind of tool your students have made! This tool may change the way armies fight! ”

Yan Zhengqing couldn't help but raise his eyebrows when he heard Colt's words, and sighed. Then Colt handed over Tu Qianjun's drawings and completely explained Tu Qianjun's description of this sapper shovel. Yan Zhengqing has traveled around Europe and the United States, and there are countless Pythagorean characters in his chest, and his broad vision is rare even in later generations! Listening to Colt's relays of Tu Qianjun's words, he couldn't help but bow his head slightly. It's not that he swept Tu Qianjun's eyes full of appreciation!

"Not bad! Junzi, you can think of this, and it's really good to design this sapper shovel! Yan Zhengqing looked at Tu Qianjun and said with a smile: "However, in terms of channels and sales, my personal suggestion is better to give it to the Colt family." After all, their family's influence in the United States and the military is still very large. It's much better than doing sales on your own. ”

Tu Qianjun nodded when he heard this, in fact, he thought so at first. It's just that if it is proposed by himself, then Colt will occupy the initiative in the negotiation, but if Colt proposes himself, he can occupy the initiative in the negotiation.

So, Tu Qianjun heard Yan Zhengqing say this, so he smiled and said to Colt: "Okay, my Uncle Colt." Then you will be in charge of the sale of this sapper shovel, but now the priority is to help me register the patent first. This patent must be in my possession. ”

Yan Zhengqing couldn't help but smile and nodded when he heard this, this is the key! Only by holding the patent can Tu Qianjun have an advantage, and this Colt is in Beijing, and he is not afraid of him playing tricks! If he is tired of playing cats, then he can't help him by slaughtering Qianjun single-handedly?! Besides, he has a good relationship with Tu Sanpao, and now he has to win over An **, and it is even more impossible to get tired of playing cats.

At that moment, Colt hurriedly pulled Tu Qianjun to the telegraph office and hurriedly sent a telegram to the United States. However, at Qi Yun's request, the caliber of the Thompson submachine gun was changed from 11.43 mm to 7.63 mm, so that it shared ammunition with the Mauser pistol, thus avoiding the problem of replenishing ammunition.

Secondly, the Browning M1917 heavy machine gun changed its caliber from 7.62 mm to 7.9 mm at the request of Qi Yun, which can be used with the Japanese Taisho 3-year heavy machine gun copied by the three eastern provinces, that is, the Liao 13-year heavy machine gun bullet. The problem of the supply of ammunition for guns was also solved.

Seeing the results of Qi Yun's negotiations, Tu Qianjun couldn't help but admire this old gentleman's freshman! You know, at this time in the United States, the price of an M1921 Thompson submachine gun is $225! This Qi Yun is good, and he bit off $45 in one bite!

And the Browning M1917 heavy machine gun is also close to $900 a piece, and Qi Yun cut off nearly $100 with a single knife! This knife is so sharp! Moreover, he also asked Colt to make improvements according to the condition of the arsenals in the three eastern provinces, which not only avoided the embarrassment of the supply of guns and ammunition, but also maintained the original quality of the two guns.

You know, after all, these two guns are produced by the Colt company, and it is impossible for someone to give you the design drawings, so if you modify it yourself, it is likely to lead to problems such as shortening the service life or accuracy errors. But if it is the Colt company itself to carry out the modification, it is different, after all, they have design drawings and the equipment is much better than the arsenal of the three eastern provinces! Naturally, instructing them to carry out the modification is much better than the modification of the arsenals of the three eastern provinces themselves.

Before leaving, Qi Yun also smiled bitterly and talked to Zhang Zuolin about Shen Honglie, the commander of the Northeast Navy, gritted his teeth and asked Qi Yun to help make peace with Zhang Zuolin and buy one or two warships with Colt. Zhang Zuolin couldn't help but laugh dumbly when he heard the news, this Shen Honglie's favorite thing has always been to ask Zhang Zuolin to buy warships for his navy.

This time this guy also got the news, so he forced Qi Yun to have to say it. Zhang Zuolin listened to Qi Yun's words, pondered for a while, and then asked Colt whether he could buy a warship.

Colt was not sure that he could buy a warship, so he could only tell Zhang Zuolin that he would give it a try. After all, the Colt family only has an excellent relationship with the Army, and the Navy does not have much to deal with. Zhang Zuolin could only give up when he heard this. That night, Qi Yun rushed back to Fengtian overnight to preside over the work of the arsenal of the three eastern provinces.
