The improved Divine Chariot rose with greater strength, and the two long-necked iron furnaces blew hot gas into the sphere together, faster than the previous lift-off time.

The chariot quickly straightened the rope that connected to the ground, and a slight northeasterly wind blew the hot air balloon to the southwest. Shen Ding adjusted the position of the wooden wheel and fan blade below, fixed the fan blade outside the hanging basket, and then connected the fan blade and the wooden wheel with a rotating rod, and then held the edge of the willow frame hanging basket, carefully stepped on the wooden wheel, stepped down with his feet alternately, and stepped on the wooden wheel with his own weight, and the wooden wheel rotated.

This time, the blades are more than three feet long, and the foot is used to step on them, so the strength is longer than the previous hand-cranking. Under the blowing of the fan blades, the hot air balloon slowly deviated from the direction of the wind and drifted towards the west.

Shen Ding, who stepped on the wooden wheel, looked still calm and relaxed, and said to Zhou Nan, "Master Dazhai, stepping on the fan blades like this, even the villain can step on it for half an hour, not to mention the brothers in the army." Besides, this magic car has a number of hours in the air, and it is not a lot to be able to stay in mid-air for an hour. This fan is also enough to use. ”

Zhou Nan nodded, when he made this hot air balloon, he only tried to do it, and did not put optimization in the first place. Now that it's an improvement, of course, it's about that. For example, if you are carrying a hot air balloon for two people, you can make the ball smaller, so that the resistance of using the fan to change the horizontal direction of the hot air balloon will be less.

The hanging basket made of willow frame is not heavy, but it can be made slightly larger, so that it can carry more charcoal fuel, so that the hot air balloon can stay in the air for a longer time. Second, you can install an extra fan to pedal the car. In this case, two people will work together, of course, the effect will be better. And in the case of two fans stepping on the car, even if there is wind, it is completely possible to adjust the direction of the two fans to achieve the positioning of the hot air balloon, instead of rushing to act when there is wind in the past.

Just like this time, he and Zhou Fu drove back to the cottage in a magic car, and the wind blew so that they could only rely on Zhou Fu to risk hooking the big tree under the cliff before returning to the cottage. If there were two fans on the hot air balloon at that time, they could have stepped on the fans and flew to the cottage.

Zhou Nan told Shen Ding and Sun Rong the points he had just thought of, and Shen Ding repeated Zhou Nan's words and said, "Shrink the sphere, enlarge the hanging basket, fill more charcoal, and two fans...... The villain made a note of it. In this way, this magic car can be easier to control. Hehe, Lord Dazhai, please see, the god car has lifted off much faster than the original just now, and the landing speed is faster. ”

Sun Rong playfully closed the two iron plates above the furnace mouth, and then grabbed a hemp rope hanging down from the sphere, and said, "The master of Dazhai is standing." Zhou Nan was puzzled, only to see Sun Rong pull the hemp rope down, Zhou Nan only felt that his body suddenly lightened, and the hot air balloon began to fall down quickly. It's like half of the heat in a hot air balloon runs off.

Zhou Nan looked sideways and looked up, and sure enough, the hot air balloon had obviously deflated. Sun Rong hurriedly shook the hemp rope in his hand and said, "Don't be alarmed, the villain in order to make the god car land faster according to what the big village master said, he opened a hole in the cowhide on the top of the god car, and then plugged it with a hollow bamboo tube, and made an opening and closing mechanism in the bamboo tube, pull it with this hemp rope, pull it down, the mechanism in the bamboo tube opens, and the heat in the god car escapes; When you release your hand, the mechanism closes automatically, and the heat is dissipated. ”

Although Sun Rong was explaining to Zhou Nan, he also paid attention to the following, when he was still more than ten zhang from the ground, Sun Rong loosened the hemp rope, opened the iron plate at the mouth of the furnace at the same time, and pushed the blower under the stove a few times, and the speed of the hot air balloon falling stopped in a distance of five zhang. It seems that Sun Rong did not practice this less when they were trying to make a hot air balloon, so that they could accurately control the landing switch and furnace fire in advance.

Zhou Nan was greatly satisfied, on the night of Chinese New Year's Eve, Gao Yun was worried that the magic of the divine car would be stolen by the enemy, so that he would be controlled by the enemy. He then described ways to attack shields with spears, such as using a special bow and crossbow to shoot hot air balloons. It's just that if you can attack the shield with a spear, then your opponent can come up with the same method. If you want to distance yourself from your opponent, you can only improve and improve your spear and shield, so that your opponent will always steal the technique of making a god car that he used in Gu'an City, and it will not be as powerful as the god car improved by the craftsmen of his worry-free village.

The divine car slowly landed, and Zhou Nan was extremely satisfied with the improvements made by these craftsmen, and he asked Shen Ding to write down the various methods of this improvement one by one, and attach the name of the improver to him. Since the craftsmen have done what they wanted, and even exceeded his expectations, he is free to reward them.

Now with the fame of the god car, the bombing arrow, etc., among the opponents, it will definitely be stolen by others. In addition, with the expansion of the Wansheng army, from the initial 4,000 cavalry, there are now nearly 20,000 cavalry troops, plus the infantry troops defending the city in various places, they may need to arm themselves with a variety of weapons in the future, and now they have too many disadvantages in this method of finding some craftsmen to make weapons at will, for example, it is difficult to keep it secret, and the craftsmen found are uneven, and the technology is different, and with the flow of these craftsmen, they will make the same things by themselves, and they will teach new craftsmen.

Now that the localities have stabilized, it is time to set up their own general as a prisoner. Zhou Nan's initial plan was to divide the supervisor into two parts, one was to gather the best craftsmen from all walks of life in Nanjing Province to form the Yanjing Research and Supervisor to develop new techniques and new handmade products; Then a large number of craftsmen were recruited to form a production supervisor, which was used to produce the things produced by the research and production supervision, and then a part of the reliable craftsmen were specially set aside to manufacture various weapons used by the Wansheng Army, among which the craftsmen who made suppressive weapons such as explosive arrows and magic cars were fixed, so that they could not worry about their skills being stolen by their opponents.

Moreover, the concentration of so many skilled craftsmen, coupled with some heavy reward and incentive policies, can definitely promote the development of skills in various industries. If a new process or product is developed, it can also be taken out, produced by the production supervisor, and then sold to various places to make a profit.

This will be regarded as the government's own workshop, and it will be given generous wages and status treatment, such as exemption from labor and military service, and it is believed that these craftsmen are vying to be the supervisor. If you enter the prison, you are not afraid that they will play tricks and not work, and they will only receive money and do not contribute. Once a year, if you fail the assessment, your salary will be downgraded, and the last level of pay will only be enough to make ends meet. For those who are capable, reward the officer.

Just like in later generations, whoever masters advanced technology will master the initiative.

"Advanced technology is a revolutionary force that has played a driving role in history." This statement is applicable in any era.
