    The most important thing is that Xia Yang has discovered that in the Huangsha Baizhan system, some raw materials are often very cheap.

    For example, the gelled gasoline he bought before was very powerful, but the price was only 500 merit points.  But a barrel of gelled gasoline purchased with five hundred merit points can produce more than a dozen powerful napalm bombs.

    "As for a finished napalm bomb, if purchased separately in the system, a single one requires 500 merit points.

    In Xia Yang¡¯s view, the Huangsha Hundred Battles system supports Xia Yang to purchase raw materials and then manufacture weapons to a large extent.  If Xia Yang could purchase raw materials and then use these raw materials to make various weapons, it would be much less laborious than purchasing weapons directly.

    "It's just that many weapons are very complex in structure. Even Xia Yang, who has been a soldier for many years, doesn't know how to make them.  Moreover, some large weapons must have a production workshop before they can be assembled.

    But things like solid explosives or colloidal gasoline can be assembled by purchasing raw materials and letting the chemist in front of you assemble them.

    "Chemistry is great! Boy, do you know about chain reactions?" Xia Yang asked.

    Hao Shiwen scratched his head and said, "Chain reaction, what kind of reaction? I've never heard of it."

    The chain reaction Xia Yang mentioned is actually the chemical reaction of the atomic bomb.  Of course, the nuclear bomb was only proposed in the later stages of the war. It is normal that Hao Shiwen had never heard of such a thing.

    Xia Yang continued to ask: "Then can you make explosives?"

    "Liquid or solid?" Hao Shiwen asked.

    "It's best to be a city." Xia Yang said.

    Hao Shiwen said: "I can do both. It's just that the state of solid explosives is more stable, while the liquid state is unstable. Without diatomaceous earth, it may react and be very dangerous. However, the solid state does not have so many requirements. I can do it if I have the raw materials.  Made.¡±

    Hearing this, Xia Yang was really overjoyed.  After a while, he came up with some other ideas.

    However, these ideas are very far away now.  When conditions are met in the future, he will practice and verify them one by one.

    The top priority now is to think about how to fight the incoming Japanese army and achieve final victory.

    "Okay, Hao Shiwen, you will be of great use in the future." Xia Yang patted his shoulder and said with a very serious look.

    Hao Shiwen smiled helplessly and said: "There is no chemical laboratory here, so what role can I play! If there are raw materials, I may be able to extract something that can kill the Japanese on the battlefield."

    Xia Yang said: "Don't worry, although it's not there yet, it will definitely be there in the future."

    Hao Shiwen didn¡¯t take Xia Yang¡¯s words seriously. In this turbulent era, anything was too far away.  In his opinion, Xia Yang's words were more like comfort and encouragement from a superior to his subordinates.

    At this time, a soldier ran up to Xia Yang and said: "Report to the regiment, those carpenters have made a sample of a trebuchet for you to take a look at."

    Hearing this, Xia Yang was very surprised.

    Last night, these carpenters were working almost non-stop.  It only took one night, but they had already made a sample, which surprised Xia Yang.

    Xia Yang then followed the soldier and rushed towards the place where the carpenters were making trebuchets.

    With more than ten meters away, Xia Yang saw the trebuchet, which was surrounded by people and was about one and a half meters high.

    This trebuchet was somewhat different from what he had seen on TV before, but it was pretty much the same.

    The top of the trebuchet is a log.  At the end of the log, there is something similar to a pallet. To use it, you need to put the object to be thrown into this pallet.

    On the other end of the trebuchet, two tendon ropes are tied.  Beef tendon rope is strong and has a certain amount of elasticity.

    When launching, you need to use a rope to pull down the log on the top of the trebuchet at one end of the pallet, and tighten the tendon rope at the other end to the limit.  It's like having a bow string fully drawn.

    Then use a mallet to hammer the cork blocking the rope. When the cork falls off, the strong tensile force of the tendon rope will provide a huge force to the log.  This will eject the contents of the tray.

    The old carpenter with some gray hair walked to Xia Yang and said: "Captain, look at this thing"Can you come out?  "

    Xia Yang walked around this thing. From the perspective of the launch principle, there is no problem with this thing.  But whether it can be launched successfully and meet Xia Yang's requirements requires some testing.

    So Xia Yang said loudly: "Come on, brothers, carry this thing to the shooting range. You guys, go and get some of the empty wine jars left over from yesterday, fill them with water, and let's experiment."

    After he said this, everyone started to work.

    More than ten minutes later, the wooden trebuchet was carried to the shooting range.

    The soldiers who were practicing shooting on the shooting range were also attracted by this big object. They stopped one after another and gathered around it.

    Several wine jars filled with water were also brought up by the soldiers at this time.

    Xia Yang picked up one of the wine jars and found that these wine jars weighed about ten kilograms when filled with water.  Excluding the weight of the wine jar itself, the water inside weighs about seven or eight kilograms.

    "If all this water is replaced by gelled gasoline, seven or eight kilograms of gelled gasoline will be extremely powerful.

    He placed the wine jar on the tray, and then the two soldiers began to pull the log down through the noose.

    The beef tendon rope on the other end made a squeaking sound, and more than ten tendon ropes were quickly tightened to the limit.

    Xia Yang looked at the shooting range in the distance, then took out the mallet and knocked on the cork, and the log was quickly swung by the shrinking tendon rope.  The wine jar inside the tray was also ejected with great force.

    Everyone followed the movement of the wine jar and saw that the wine jar drew an arc in the air. After flying for about two seconds, it fell to the shooting range with a bang.

    Xia Yang said loudly: "Measure the distance!"

    As soon as he finished speaking, some soldiers began to measure the distance.

    After a while, a soldier ran over and said: "Report to the regiment, the projectile distance is 150 meters."

    Hearing this, Xia Yang frowned. If it was only 150 meters, it was too short.

    So Xia Yang continued: "Make the wine jar lighter and see if it can be thrown farther." (Remember the website address: www.hlnovel.com
