"Hey, have you heard? Our new section leader is actually a woman, and I heard that she is also very beautiful, and it seems that she was specially transferred from the Shanghai Special High School. "There are two men in black squatting under the wall, it is the middle of the day, and there is just a shade here on the wall, and it has become a place for many special high school students to smoke and chat. Unlike the Japanese military special high school in other places, most of the field staff in the Tianjin special high school are Chinese, and only the supervisors and some key departments are all Japanese.

The two field agents only cared about smoking, but they didn't want their words to be heard, but outside the courtyard separated by a wall, there was a pair of young men and women. "Chief Nagumo, they're talking about you." The burly man whispered to the woman, who just shook his head and smiled, and then quietly continued to listen to the voices within the walls. Unlike most of the super-high course directors who are engaged in intelligence work, Nagumo Nobuko looks like a schoolgirl next door, and no one would have imagined that such a good-looking woman would be a murderous and unblinking super-high super-high director.

Transferred from Shanghai to Tianjin, this was not what Nanyun Nobuko wanted, but this was an order from his superiors, and the helpless Nanyun Nobuko had to come to Tianjin with a personal servant. It has been three days since I came to Tianjin, and in these three days, Nanyun Nobuko took her relatives to walk through Tianjin. "Boom..."An explosion suddenly sounded on the street not far from the station of the Tianjin Special High School, and Nanyun Nobuko's face changed, and he immediately asked his relatives to go over to check, but he returned to the courtyard of the Special High School.

A moment later, more than a dozen special high school staff rushed out of the yard and went straight to the scene of the explosion according to Nagumo Nobuko's order. The three cars sped towards the street, but when they were only 30 meters away from the street, something strange suddenly happened. With a "boom" sound, the first car exploded and turned into a ball of fire, and the two cars immediately braked and stopped, but the bad luck did not go away from them, with a sharp sound of breaking the air, a red crossbow arrow shot from the roof of the street flew straight to the last car.

The moment the "boom" red crossbow arrow touched the car, it exploded, and several special high school staff in the car did not react, and they were engulfed in flames along with the car. "On the roof, on the roof." Several of the extra-high school students in the middle car were smart and immediately got out of the car, and at the same time, someone was already pointing to the roof where the crossbow arrows had come and shouting loudly. The red crossbow arrows of the "boom" advantage hatred came fiercely, and the car in the middle immediately turned into a ball of fire, and several special high school students who had already gotten out of the car had fled into the shops on the street.

From the explosion of the first car to the escape of the surviving special high school students into the shops on the street, the whole process was actually only a short little more than a minute, and when the reinforcements of the special high school who got the news arrived here, nothing was found on the roof where the crossbow arrows were fired earlier. "Baga, you idiots, immediately expand the search area, if necessary, you can block the streets and conduct a house-to-house search, and you must find the attacker for me."

Nagumo Nobuko, who had already changed into a Japanese military uniform, looked a lot more severe, and he had just arrived in Tianjin, and the local anti-Japanese forces gave him a dismissal, which made Nagumo Nobuko very annoyed. Although they also arrested some so-called suspicious people, Nagumo Nobuko knew in her heart that these so-called suspicious people were just an excuse, because the special high class needed a fig leaf to hide his incompetence.

Lu Yuan, who had succeeded in the first blow, had actually already left that block, and the steel crossbow had already been put into the storage space by him, and Lu Yuan also did not expect that after adding explosives and impact fuses to the crossbow arrows, the power of the crossbow arrows would be so terrifying. Lu Yuan, who had a smug face, did not pause in the slightest, returned to the trading house, and then locked himself in the basement, and began to continue to process and improve the explosive crossbow bolt he had designed.

When Lu Yuan first went to Germany, he handed the German army a design drawing of a man-soldier bazooka, but the German side never replied, and Lu Yuan, who had been looking forward to using a man-soldier bazooka, was greatly disappointed. Combined with explosives and crossbow arrows, this was just an immature idea that Lu Yuan accidentally thought of on the way back to Tianjin, and the crossbow and crossbow arrows used today were only test samples made by Lu Yuan, but the effect made Lu Yuan overjoyed.

The basement of the comptoir has already been focused on and supervised by Schuhmann and Hogg, and not only is it much larger than the basement of Lu Yuan's residence in Shanghai, but the machinery and equipment inside are also brand new. Lu Yuan only needed to close the two layers of soundproof doors, and even if Lu Yuan started those machines in the basement, the trading houses above would not hear the slightest sound. After the previous three test firings, Lu Yuan had some new ideas about the crossbow arrows he designed, and after making several hollow crossbow arrows in a row, Lu Yuan began to carve threads in the tail of the crossbow arrows.

The crossbow arrow made by Lu Yuan at this moment is cone-shaped, and the hollow part is used to fill high explosives, and at the top of the crossbow arrow, Lu Yuan also leaves a hole for the copper impact fuse. After doing all this, Lu Yuan took a wooden arrow shaft on the shelf, cut the arrow shaft in two with a knife, and then pulled out the thread on the half-cut arrow shaft with the tail wing, and then used the thread to connect the arrow shaft and the arrow shaft into a whole crossbow arrow.

"It looks a little worse, but the power should be stronger than before." Looking at the finished crossbow arrow in his hand, Lu Yuan's face did not show too much joy, at this moment the crossbow arrow in his hand looked very weird, the steel arrow part was almost the same as the entire crossbow arrow, the wooden arrow shaft part seemed to be a little fluttering, and the whole crossbow arrow looked very unbalanced. Lu Yuan carefully studied the crossbow arrow in his hand for a while, and then continued to get busy, he decided to make an all-steel crossbow arrow.

In order to add high explosives, the arrows must be hollow, but Lu Yuan also made the shaft of the arrow hollow this time. After Lu Yuan's advance, the arrow and the body of the crossbow arrow became a hollow one, and the steel tail of the arrow not only had a tail fin, but also a thread, which could be screwed together with the arrow shaft. The body of the arrow is also made hollow and can be filled with explosives, and the charge of the crossbow arrow can be at least twice that of the shelf, although there is no test shot of this improved steel crossbow arrow, but Lu Yuan knows that the power of this thing will definitely not be so small.

Lu Yuan made and loaded three of these steel crossbow arrows in one go, and then took out the steel crossbow from the storage space to improve, and after adding a pair of eccentric wheels to the crossbow, the speed of the crossbow winding was much easier, but the firing distance was not reduced much, and the flat shooting distance of 60 meters had already made Lu Yuan very satisfied. Lu Yuan carefully colored the crossbow arrows with red paint, and then waited for the paint to dry physically and mentally, but his mind was thinking about where to go to test shoot the newly made three crossbow arrows for a while.

When it was time for dinner, Lu Yuan came out of the basement, and Hogg, who had gone out to run errands, had not yet returned, and only Lu Yuan, Wang Hu and Shu Heman were the only three people who ate together. Wang Hu has been playing crazy these days, after eating breakfast, he was taken around by Shu Heman to play, if it weren't for the fact that he had to finish eating with Lu Yuan, maybe Wang Hu would still be hanging out in front of the food stalls on the street. "Boss, I heard that there was an accident over there today, and three cars were destroyed and people died." During the meal, Schuhman seemed to inadvertently talk about the Tianjin special high school class in front of Lu Yuan.

Lu Yuan refused to admit this, and claimed that he had been in the basement all day, and if Schuchmann didn't believe it, he could go to the basement to check the use of the machine. It was naturally impossible for Schuchman to go to the basement to check what Lu Yuan said, and there was still a Wang Hu sitting at the dinner table, so Schuchman did not ask too many questions and temptations. After dinner, the tutor Lu Yuan invited to Wang Hu came to the door on time, and when Wang Hu, who was full of sorrow, was taken upstairs by the tutor, Lu Yuan also found an excuse to leave the firm.

The atmosphere outside the concession was obviously much more tense, and the incident of the attack on the special high school during the day had already been rumored, and in Lu Yuan's all-view map, there were undoubtedly many more spies and gang members on the streets, who were working for the special high school in the open and in secret. Lu Yuan, dressed as an ordinary student, walked casually among the pedestrians, until he got into a small alley on the side of the street, which changed his previous lazy appearance, and the man had already climbed the wall in the alley to the roof next to him after a few clicks.

Lu Yuanxian, who went up to the roof, squatted quietly for a while, and only after his eyes had adjusted to the gradually darkening sky did he take out the crossbow from the storage space. Diagonally opposite Lu Yuan is a Japanese restaurant, and there are not a few people who enter this Japanese restaurant, and in only half an hour, Lu Yuan on the roof saw with his own eyes that there were five Japanese officers entering and leaving this Japanese restaurant.

"It's you" Lu Yuan immediately took out a crossbow arrow from the storage space, carefully screwed the impact fuse on the top of the crossbow arrow, and Lu Yuan immediately picked up the crossbow with the crossbow and aimed at the Japanese restaurant. Time passed little by little, but Lu Yuan on the roof kept squatting posture, and the crossbow arrow in his hand never shot out. About a few minutes later, just when Lu Yuan was about to choose to give up, a black car stopped in front of the Japanese restaurant.

Lu Yuan immediately came to his senses, and with the help of the light at the entrance of the Japanese restaurant, Lu Yuan on the roof saw that the first to get off the front passenger seat of the black car was a Japanese soldier. Could it be that there are still Japanese officers with a higher rank than Shaozuo in this car? Seeing the Japanese soldier Shaozo turning around to open the door, Lu Yuan immediately became excited, and at the moment when the Japanese soldier Shaozo opened the back door of the car, Lu Yuan, who had been waiting for a long time, finally launched the first crossbow arrow.
