"No, just one grenade is not enough. I think we'll have to toss and turn again, and it's better to get things like artillery and Makqin heavy machine guns. Cheng Siping said with thought to himself.

The system was completely speechless, and simply stopped dealing with Cheng Siping. Cheng Siping didn't pay attention to its reaction, just did it, stood up directly, took a pen and paper, wrote and painted.

If you want to get the artillery out, it's relatively simple. At this time, Cheng Siping could not have made a howitzer with a 155 caliber and a 55 times body barrel range of more than 40 kilometers in Huaxia. But like some medium-caliber artillery guns of the First World War, it was not difficult for him to come up with them.

Gunpowder has ready-made picric acid explosives, and the barrel is not a big problem. Although the smelting technology of the Guiyuan Realm is still based on artificiality, the blacksmiths here, or the refiners, have taken a different path from the smelting technology in Huaxia. The steel they smelted is no worse than the special steel in Huaxia in Cheng Siping's previous life in terms of strength, toughness, etc. In some ways, it even goes beyond that. Let them build the barrel, except for the limitation of production, there are no other problems at all.

Come to think of it, to make a cannon, there is only one thing missing: a primer. As for the choice of the primer, Cheng Siping flipped through it in his divine sense, and finally chose a relatively old primer, mercury thunderate. Although this thing has the problem of instability and corrosion of the barrel, there is one advantage in front of it, that is, it is relatively easy to obtain. Cheng Siping didn't want to toss too much at this time, so he decided on it for the time being. As for whether it will be changed to something else in the future, then we will talk about it later.

The problem with artillery is not big, but the Maxim heavy machine gun is a bit more difficult. There is a saying in the field of military firearms manufacturing that what kind of bullet there is, what kind of gun there is. Cheng Siping was also facing the problem of making bullets at this time, not the problem of making guns. The body of the gun is easy to handle, this kind of water-cooled gun, those blacksmiths in the village can get it without much effort. The main problem is still in the bullets, the Makqin heavy machine gun uses smokeless gunpowder, and without smokeless gunpowder, the gun will not come out at all. However, it is not as easy to make smokeless gunpowder as bitter acid and mercury leiate. It is estimated that Cheng Siping is still experimenting with research.

After two days of writing and painting on the mountain beam, Cheng Siping came down the mountain with a bunch of drawings and fruits. At this time, the production of grenades in the village was gradually on the right track. Now the daily output has reached seven or eight hundred, and with the proficiency of the villagers, the production efficiency will slowly increase.

Cheng Siping inspected the production and manufacturing of grenades, but was not very satisfied. On the spot, he put forward more than a dozen suggestions to Zhu Sheng, who was in charge of this matter, and mixed the assembly line production model of his previous life into it. After listening to Cheng Siping's suggestion, Zhu Sheng had a sense of openness, and immediately summoned people to transform the entire production line.

After instructing Zhu Sheng to transform the grenade production line, Cheng Siping immediately summoned several of the most skilled blacksmiths in the village to study the tools for making Lei Acid Gong. The utensils used to make this thing are actually similar to the ones used to make picric acid, and it is not too difficult for the blacksmiths. After they looked at the drawings, they began to prepare for trial production. However, before their trial production, Cheng Siping gave them a very solemn advice in case of accidents. After all, mercury thunderate is different from picric acid, and this product is very unstable.

Seeing that Cheng Siping cared so much, the blacksmith also put away his previous contempt and agreed very respectfully. Subsequently, Cheng Siping no longer mixed with them, and took Guoguo directly out of Xuanyuan Village. He came out this time, mainly to go to the extraction materials of smokeless gunpowder. The extraction materials of mercury thunder acid and picric acid occurred in the Nanban Black Forest early in the morning, so he only needed to call someone to mine. But this smokeless gunpowder, refining materials have not been found. There were quite a few recipes for smokeless gunpowder given in his divine sense, and he hadn't decided which recipe to use yet, because it was because of the refining materials.

Cheng Siping wandered around for a day, carefully explored the surrounding minerals again, and roughly confirmed which formula to choose for smokeless gunpowder, and then returned to the village. The blacksmiths in the village were still busy making the materials for Cheng Siping to make mercury thunderate, and the others were engaged in the production of grenades. But Wang Linyuan, at this time, came to remind Cheng Siping that the food stored in the village was only enough for seven days.

If you don't have enough food, that's a no-no. According to Cheng Siping's prediction, the village would have to store at least more than a month's worth of food. Now it's only seven days, and that's definitely not going to work. At the moment, he put aside the matter of making cannons for the time being, and selected seventy or eighty strong ones to go out of the village tomorrow to hunt beasts.

This time the beast hunting, in addition to being led by Cheng Siping and Guoguo as usual, each villager also brought five grenades. It is not only to hunt beasts, but also to test the effectiveness of grenades.

Before leaving the village, Cheng Siping decided to first raise his Daoist cultivation to the realm of ascending to the hall. Because he was worried that this promotion of cultivation would attract some visions like last time, Cheng Siping deliberately returned to the mountain beam and brought Guoguo to protect the Dharma, so he was ready to pour the battle value into the cultivation of the Taoist. His battle value at this time was 2532 points, which was completely enough to directly ascend to the realm of ascending to the realm. In order to ensure success, Cheng Siping also deliberately bought a pill of the Fourth-Order Qi Gathering Pill first, for which Cheng Siping also had a pain in his flesh for a while.

After taking the Qi Gathering Pill, the aura of heaven and earth began to change, and Cheng Siping immediately gave instructions to the system. Soon, with the injection of combat value into the system, the true qi in Cheng Siping's body seemed to explode into a pot, rushing left and right like a bull in the meridians. Fortunately, Cheng Siping's meridians have also been exercised, and this impact has not caused much impact. Cheng Siping came back to his senses, and according to the Taiyi True Scripture, he wrapped up these chaotic true qi little by little and sent them to the dantian.

The true qi was still not so tame in the dantian, so he drew it out again, and walked in the body of Zhou Tian. One, two, three...... With the rapid operation of the Taiyi Sutra, Cheng Siping slowly entered a state of forgetting about things and me.

I don't know how long it took, Cheng Siping suddenly woke up, opened his eyes and looked at it, and at the same time used the true qi in his body. The Yin Seesaw Veins and Yin Dimensional Veins in the body have all been opened, and the True Qi is constantly running, and it is not much stronger than before.

"Is this the realm of the Taoist's ascending to the hall, it is really different. Cheng Siping threw a punch and sent out, and the strong true qi immediately whistled a wind.

"Brother weak, you are good. Guoguo heard Cheng Siping's voice and ran over, but she didn't notice the change in Cheng Siping's momentum, but said: "Fortunately, you are better now, otherwise it would be too late to hunt beasts." ”

"Uh......" Cheng Siping glanced up, only then did he realize that it was already daytime at this time. In other words, it actually took him one night to attack the Daoist Ascending Realm......
