The meeting was very long, and for the sake of secrecy, no one was allowed to leave the guest house. There are also a lot of manpower inside and outside the house to prevent anyone from eavesdropping or passing on messages. Jiang Chen: For the rest of the time, they ate and lived in the guest house, and they couldn't step out of the house at all. In addition to meetings, the group still had meetings, and this small conference room was always full of smoke all day long. Everyone put forward a plan, and then it was immediately vetoed, and after tossing and turning for three days and three nights, they finally formulated a plan for the operation, and the task code name was 'Autumn Sowing Plan'.

In fact, this code name has been mentioned a lot, such as what is the 'Tianlei Plan', what is the 'Hail Plan', what is the 'Dragon King Plan', etc., and in the end, Jiang Chen proposed this 'Autumn Sowing Plan', which was unanimously recognized by everyone. It not only represents the characteristics of the task, but also perfectly guarantees the confidentiality of the very important work. The so-called autumn sowing is actually autumn sowing, which happens to be autumn at this time, just right. It is the seed that is sown, because it is to be in the ground like a landmine. Then it takes root and sprouts and then blooms, and the flowering here has two meanings, one of which is the flowering explosion, because we know that our ancient cannonballs that can be exploded are called flowering shells. This two is because it is able to blossom and bear fruit to bring them good results.

The plan is made, and the implementation begins. There is also a problem with this, you have heard of cluster bombs, and we have tried to produce them, but how to make this cluster scattered mine bomb, this can be a problem. There are many plans from various people and institutions, but Jiang Chen has very few of them. didn't do anything, as Jiang Chen, who was in charge of the technical aspect of the real plan, he should have taken on the heavy responsibility of manufacturing research and development. Although they have a lot of plans, they are all complicated. It is not suitable for use in this kind of tropical jungle, so Jiang Chen's request is to simplify the mechanism as much as possible. Because when your structure is simple, then your failure rate will be reduced. Moreover, it can work for a long time, having achieved the strategic purpose of long-term paralysis of lines of communication behind enemy lines, which was previously formulated.

Among these many plans, there is a small factory's plan that makes Jiang Chen's eyes shine. That is to use a timer device that causes these small mines to be activated after they are spilled in the mother bomb. After the bomb lands, the timing device stops or the time is up. The safety of the trigger device on the mine is opened, which completes the work of excitation standby. Originally, this small factory was going to use some more complicated calculation tools such as clocks or hourglasses, but these were all vetoed by Jiang Chen, and he directly took out a clockwork frog (one of the toys I used to play with when I was a child, this is one of the representative objects at that time) from his pocket and put it in front of everyone. Everyone was a technician, and they knew what Jiang Chen was referring to at a glance, so they all got excited.

In order to ensure the reliability of these small mines, they cannot just be put into the battlefield. Jiang Chen: They have to do a lot of experiments in the early stage to ensure that these devices can operate normally. At first they were thrown up and down on several floors. Reliability of the experimental setup. When this reached a certain standard, Jiang Chen and the others began to carry out the next step of experimental work. Because it is a device, it also has a failure rate, which is unavoidable, and it may be that even a small chance change can make the device stop working. So since you can't avoid it, let it be within an acceptable range, such as a 1 percent probability.

The next step is to conduct a live-fire drop experiment, which is also the final step of testing, and if it is suitable, it can be mass-produced according to the standard. Of course, this live-fire test is not all live-ammunition. No one wants to put a minefield on our territory, so none of these mines are charged. Only the trigger device is real.

For this experiment, Jiang Chen and his team specially transferred a strong five from the air force, carrying a cluster scattered mine bomb that Jiang Chen and they had developed for the experiment, and ten minutes later, the plane dropped the bomb at the planned altitude. Of course, this height is still very high, taking into account the enemy's anti-aircraft fire. So the Air Force requires that you must avoid this altitude in order to drop bombs. In one minute, these small mines scattered by cluster projectiles are evenly scattered in a preset area. Then Jiang Chen immediately took people to check in the early stage, and the result made Jiang Chen and them disappointed, that is, the successful ignition rate of these mines was too low, and none of the ten mines were good, which made everyone very frustrated.

However, this political commissar Shi is a veteran of ideological work. When they knew that Jiang Chen and their experiment failed, they did not reprimand, but personally brought many condolences to comfort everyone. After Political Commissar Shi did the ideological work, everyone began to cheer up and find out the reason. Finally, it was the emperor who lived up to his wishes, and Jiang Chen and the others found the cause of the device's malfunction. There is nothing wrong with the device itself, but there is a problem when it is thrown from a high altitude. Because of the high distance, combined with the acceleration of gravity, the force of the device in contact with the ground is very high.

At the beginning of the period, Jiang Chen's design was to use this power to bury these devices under the soil, so as to play a concealment role and increase the enemy's search and demining time. But Jiang Chen and the others miscalculated, because under the impact of such a large force, the device itself would be damaged, so it would not be able to work normally. After finding out the reason, Jiang Chen and the others quickly found a solution.

What's more, that is, to add a small parachute to these small devices (mines) that are thrown to reduce the speed of the device's fall. Although they couldn't hide in the ground, Jiang Chen and the others also found a solution. That is, the material of these parachutes is made of paper that can be dissolved by rain, and when these parachutes land, they can melt in natural rain or artificial rain, and these thin wires used to connect the parachute and the device naturally become tripwires, increasing the probability of triggering the device. In addition, because the soil in the jungle area is very soft and the vegetation has a lot of fallen leaves, these devices can be hidden after the rain, so that they will not be easily found and eliminated by the enemy.

After several repeated experiments, Jiang Chen and the others finally succeeded. Moreover, the leaders of the former finger also inspected the final experiment on the spot, and they were very satisfied with the results of this experiment. So he began to make a decision to end the preliminary preparations and officially implement the 'autumn sowing plan'.

The wait was probably late November, so the required cluster dispersal mine munitions had been expeditiously produced at factories across the country, and then quietly arrived at the airport for secret storage. Aircraft of all types, secretly transferred from all parts of the country, have been waiting in concealment at the nearest airports, just in case dry ice rockets have arrived at the front line, waiting for the best time to come.
