Xiao Zhenying did not argue with Yang Feng's words, but after the Japanese army took Rehe, his next target would definitely be Chahar, and he understood this very clearly.

Next, the 29th Army will face the Japanese directly and win over Sun Dianying and Feng Zhanhai's troops will definitely be beneficial and harmless. As for whether Sun Dianying will affect the 29th Army's dominance against Chahar, he is not worried at all. Just Sun Dianying's mob, all the elite 29th Army of the Northwest Army did not take it seriously.

"What is Brother Yang's specific idea?" He asked Yang Feng inconspicuously.

"It's very simple. The remaining troops of the 29th Army sent some cavalry, and then Sun Dianying and Feng Zhanhai each selected some cavalry, and the three families joined forces to fight back to Rehe. With their speed, they attacked the Japanese rear and took back one or two cities if they had the chance. At the same time, a bluffing counterattack was launched at the front line of Xifengkou. Regardless of the final result, the 29th Army, the 41st Army, and the 63rd Army will surely gain a reputation." Yang Feng said.

"This is indeed a good idea, but what about your benefits, Brother Yang?" Xiao Zhenying thought about it and asked.

"It's very simple. He Yingqin agreed to build an arsenal in Peking. Of course, there is no need to use the arsenal. As long as you allow me to make weapons, I'm already building mortars now, and the yang army hasn't bought them."

Because the 29th Army and the Ministry of Shang Zhen used Yang Feng's mortars to achieve great results, the Peking Military and Political Committee also purchased fifty gates, and now half of them are in Guan Linzheng's hands. However, it is an extraordinary period, so naturally they will not argue with Yang Feng. However, if Yang Feng still wanted to continue building arms after the war, it would be a bit sensitive.

"This should be fine, I'll talk about He Jingzhi!" Xiao Zhenying agreed happily. In fact, he was even happier. What the 29th Army lacked was the arsenal. With the relationship between Yang Feng and the 29th Army, if he built arms, he would definitely supply his own place in large quantities.

The situation is so serious now that He Yingqin would not mind such trivial matters. Everyone knows that if Sun and Feng's army returned to Rehe, the Japanese army on the Great Wall line would inevitably return to defense, and Europe, the United States and other countries were also mediating at this time.

Although Japan withdrew from the League of Nations, it is very likely that it would be possible for Japan to withdraw its troops from the Great Wall to accept mediation and start negotiations. At that time, the 29th Army will become the biggest winner in this war.

Yang Feng didn't need to worry about the next thing. He just needed to wait for the result. After Huang Jie's army joined, the Gubeikou Front finally firmly defended the South Heaven Gate. Because it had been confirmed that the Japanese army was unable to attack Chahar, Fu Zuoyi's troops, who had originally planned to defend Dushikou, were also transferred to Gubeikou. At least in the short term, the Japanese army has not had the possibility of breaking through the Great Wall defense line, but they dare not be too absolute. After all, the Luandong area under the Northeast Army is still a little worried.

In fact, Yang Feng's concerns were very reasonable. The progress was slow at Gubeikou. The Japanese army, which was seriously frustrated at Xifengkou, quickly began to adjust the direction of attack. In addition to Gubeikou still maintaining pressure, Xifengkou moved into defense at the front line and transferred all the main forces to the east of Lengkou. The pressure of Shang Zhen, He Zhuguo, Pang Bingxun and other units increased sharply.

However, at this time, Yang Feng ushered in a great joy.

"Yang, it's a pleasant good news. Your sulfonamide patent application has been approved. It is estimated that the patent certificate will be sent to China soon." Richard said with a full face.

Several batches of sulfonamide delivered to the United States have made Pfizer famous. This special drug with amazing effects has almost caused a sensation in the United States as soon as it was used. Because Yang Feng allowed Pfizer to sell it with his own trademark, it put great pressure on its competitors. The happy Pfizer executives rewarded Richard with great rewards. He can't wait to win the production rights of sulfonamide.

Unfortunately, his happy mood was not rewarded. Yang Feng was still like a slave exiled by the emperor, sitting there sighing with a sad face full of worry about the country and the people.

"Mr. Yang, isn't this news worth celebrating?" Richard asked cautiously.

"Oh, the country is weak and internal and external troubles, how can you be happy for me?" Yang Feng sighed and said listlessly.

"This," Richard smiled awkwardly and said, "Yang, we are all businessmen. Your government and the army are worried about these things. We only need to make money with peace of mind and pay taxes according to law. There is no need to worry about this. Besides, I think the international community will not continue to sit idly by and watch the Japanese attack on North China."

"International community? People don't play with you anymore, and they will still care about the international community." Yang Feng said excitedly.

"Yang, don't worry, even if the Japanese occupy Peiping, everything about you will be protected by the United States. If you want, I can help you and your two girlfriends get American nationality now." Richard's words were sincere, but now he can't let Yang Feng get anything happen to him.

"I have recognized your kindness. The nationality can be changed. Can the blood flowing on my body be changed?" Yang Feng clenched his fists and was excited again.

"Yang, I have no other intentions, just for your safety." Richard quickly explained.

"I'm a little excited, don't mind, alas, the mountains and rivers are broken!" Yang Feng wiped the tears that did not exist with a tissue.

Richard was not stupid. The guy's performance in front of him was obviously deviating from his style. He probably had a lot of performance. According to his understanding of Yang Feng, once he began to be sensational or serious, it would show that he was brewing some conspiracy in his heart.

"Yang, is there anything I need my help?" Richard simply made it clear.

"I need arms, as far as I know, American merchants in Shanghai have a large number of arms. If you can get it for me, I will need them no matter how many, and I will use medicine to pay for the goods, sulfonamide, Vanaike, and this thing." Yang Feng said as he took out a box of TT from the drawer.

"Is this?" Richard took one apart and looked at the little thing blankly.

"Don't you think that life will be completely perfect when it is used in conjunction with Vangaike?" Yang Fengzhen said with a smile.

Richard pulls a thread TT.

"Oh, mygod!" He immediately exclaimed with excitement.

"This should be much better than oral contraceptive pills, right? You also know that that thing is harmful to women's bodies, but this will not have any side effects, and you don't need to worry about contracting some bad diseases. I have issued a patent application to the United States and Europe. I think Pfizer should be willing to be its general agent in the Americas, right? Think about it, how many Americans need this kind of thing every day? The price is not expensive. I can sell it to you at a price of ten dollars per dollar. As for how much you sell, I won't care." Yang Feng lay beside him and said with a temptation.
