The 12.7mm white phosphorus bullet whipped hard on the abdomen of the Japanese aircraft like a long whip of flame. Bullets as thick as fingers easily penetrated the wooden fuselage. The frictional heat quickly ignited the white phosphorus. Almost in the blink of an eye, the Chuanqi Type 88 light bomber ignited the flames.

Not only that, the penetration power of large-caliber bullets is obviously a bit too cruel for this aircraft, which is mainly composed of wood and canvas. Several of them actually penetrated the entire fuselage and penetrated the pilot's body from below. Then, the bomber that had not had time to drop a bomb flew straight over the head of the cargo cargo and hit the city wall in the distance, instantly turning into a dazzling flame.

"Damn it! It's so powerful!" Yang Feng shouted excitedly.

The other three bombers of the same model immediately stopped the ongoing bombing and rushed over without hesitation.

Yang Feng suddenly accelerated to more than one hundred, rushed towards the city gate like an arrow, and dense bullets hit the car body and made a sound. The two little girls were so scared that their faces were pale, but Yang Feng was excited as if they were smashed by money.

The three bombers beaten the big man behind the front of the car and shrank the front of the car, not daring to show up at all. Even the sixth and the other two were lying behind the steel plate and not daring to move.

Of course, such an attack was obviously meaningless for the foyer that could not even be used to combat defense artillery. Yang Feng still rushed out of the city without any damage. The three Japanese bombers seemed to be angry by the death of their companions, and they all gave up their missions and followed behind and chased them relentlessly.

There is nothing to worry about when Yang Feng leaves the city. To be honest, if it weren't for the fear of being too shocking, the small cart would jump to a speed of 300 per hour, and it wouldn't be a problem to get rid of these planes. The bombers of this era were only 300 at the fastest, and it would burn the incense if they could fly for 200 bombs.

Outside Miyun City is a large farmland, which is suitable for him to play driving skills. The small cart is like a cunning fox, walking skillfully among the fire balls of bomb explosions, and would stop from time to time to let the machine gunners behind him harasse the Japanese plane.

The Japanese planes were not like him, and they had enough time to play. They had not left much time to bomb when they flew from the airport in Suizhong. This cat and mouse game was played for only a dozen minutes. Three planes that cast all the bombs and even fired all the bullets had to fly away helplessly.

When Yang Feng returned to Miyun again, he was welcomed like a triumphant hero. Many people watched his performance on the city wall. Everyone understood that if it weren't for Yang Feng's planes that led away the Japanese, those powerful bombs would have killed many ordinary people.

"Actually, my brother didn't think so much. He just felt that he had weapons and could not watch the Japanese harm the villagers." Yang Feng said to the local tyrants and evil gentry surrounding him with a simple expression that subverted his image.

The hero who saved the people, with satisfaction, led the convoy to Gubeikou with amidst praises. Because there was strong firepower to rely on, the civilians and students who went north from Miyun to follow him very smartly. The long convoy moved slowly forward. Before dark, they finally arrived at Shixia Town, which was the rear base of the 25th Division, and then moved forward to the battlefield.

Going up the Chaohe River, Gaoling Town, Loess Liang, Nantianmen, and then to Gubeikou, these series of passes are blocked layer by layer, forming a complete defense system, firmly protecting the Chaohe Valley, the deadliest gap on the Great Wall defense line.

At this time, Guan Linzheng still led the remaining troops of the 25th Division to defend about 5,000 people at Gubeikou. The Japanese army opposite him suffered a lot of casualties, especially when the war started, almost an artillery brigade was blown away by Guan Linzheng's artillery. The infantry also suffered heavy losses due to lack of artillery support. Therefore, the offensive weakened during this period, and the two sides fought stalemate.

At this time, Shixia Town was filled with wounded soldiers waiting to retreat. The bloody scene in the field hospital made Xin'er and his face pale. Yang Feng didn't care about this at all. He had a good psychological quality. In addition, he had seen it a long time ago, so he still held the cardboard box and smoked everywhere.

"Mr. Yang, you won't just bring cigarettes, right?" Yang Feng was smiling and studying the female body structure with several wounded soldiers. Suddenly, a delicate voice said behind him, and the wounded soldiers around him immediately dispersed.

Yang Feng turned around and Helen, wearing a white nurse's uniform, put her hands in her front pocket, stood there pretty, looking at him with a smile.

"Why are you here?" Yang Feng asked in surprise.

"I'm a volunteer, and my father is here, too." She shrugged.

When Yang Feng heard this, he immediately became energetic. He hugged her shoulder with suspicion and said mysteriously: "I have a new drug here that has an immediate effect on infection after surgery. Do you want to test it?"

"More effective than sulfonamide?" Helen immediately became energetic and asked in surprise, without noticing Yang Feng's downward look.

"It's very effective, it can be said to be a god-like effect." Yang Feng nodded fiercely as if pretending to behave.

It's time for penicillin to appear. Now, all hospitals in Pingjin, including Peking, are crowded with wounded soldiers. This time, Yang Feng brought back 5,000 penicillin injections. Considering that people at this time were not resistant to drugs at all, these 5,000 can be used as 50,000. Now it only needs a beginning of spread. Helen and his daughter are honored to take on this important task again.

It must be noted that Helen's father Lucas, an old alcoholic, was a field doctor during World War I. He was very famous in surgery. Unfortunately, after his wife died, she was not sure what kind of stimulation she was, and she began to be drunk. Later, there was an accident during the operation, and she couldn't survive in the United States, so she simply ran to the distant China and opened a clinic here to live. Many people in Western hospitals in Peking also knew about him, so some difficult surgeries often asked him to help.

Helen came to China with him since she was ten years old, and even attended Tsinghua University in college. Except for her Western face, she was not much different from Chinese girls in other aspects. Because of this, she was as popular as an angel among the Westerners in Peking.

During this period, Yang Feng has been using her as his free advertising model. At least sanitary napkins have spread among Western women in Peking. Yang Feng's patent application has been sent to the United States and Europe long ago. The patent application for shorts matching sanitary napkins is also issued. Yang Feng even planned to bring a bikini over in the summer. When he thought of Helen's sexy body wearing a bikini and walking on the beach, Yang Feng couldn't help but feel the urge to bleed from the nose.
