"Ah! Brother Quan, this lump is not good enough to be used as marbles!" Yun Shu shouted to Wang Gongnan in horror when he heard the wild cry of the Bai family in the dust.

"Uncle Yun, it's not that the marbles are not enough to be filled, but they are too few. The number of enemies rushing towards him is not large, and it seems that he is not injured if only a few people are injured. Hurry up, install more." However, Wang Gongnan's spiritual sense was powerful. Although the dust raised by the cannon in front made it impossible to see things clearly with his eyes, Wang Gongnan's spiritual sense still sensed, and some people were still killed by the cannon. So he immediately said to Yun Shu.

Before, he only asked Yunshu to put on a little iron lump and try it out, but in fact he was very worried. Because his soul knew the situation of cannons in his previous life. If the ammunition model is not worthy, it will not be able to fire the cannons, and even if it can fire it, it will be easy to explode.

Therefore, Wang Gongnan was also worried about the danger of explosion of the marbles that were different in shape and size from the marbles used in the previous intensive cannon. So he secretly opened the Red Purple Clothes World, preparing to use the collection function of the Red Purple Clothes World to immediately use the collection function of the Red Purple Clothes World to put Yun Shu and others into the Red Purple Clothes World.

"Okay!" After hearing Wang Gongnan's words, Yun Shu opened the cannon's loading box while Lu Chu operated the formation, and immediately loaded the beast core and took out some iron lumps to put it on. However, he was naturally worried about the explosion, so he just put half of the iron lumps than before, and was far from filling the loading box.

"boom!"

The cannon fired.

But this time, the sound was obviously louder than the first time, but it was not as loud as before or as before.

"Brother Quan, how about it? Do you need to add it?" After the cannon fired, Yun Shu couldn't wait to shout to Wang Gongnan.

"Ha! It's totally OK! The iron lump was a little softer, and when it exploded, it was full of fragments. Although it couldn't hit the human body like a dismemberment, it could still kill people.

Uncle Yun, I already know how many iron lumps to be released from the sound of the cannon. It is three times more than just now." Wang Gongnan responded to Yun Shu with a big laugh.

"Okay. But if you put three times more, you still haven't filled the filling box." Yun Shu replied.

"Uncle Yun, don't fill it up. We must put safety first. Now that the cannon is constantly firing, the cannon body is already very hot. With this heat, the cannon barrel will naturally soften. And the iron lumps we use now are too irregular, and some are still sharp. So, I'm afraid this thing will damage the cannon barrel." Wang Gongnan said.

"Okay." Yun Shu replied. Then, Lu Chu quickly operated the array to open the loading box. Yun Shu immediately loaded the beast core and filled the iron lumps according to the amount Wang Gongnan said.

"Boom!" The cannon sounded, and the sound was actually the same as when loading marbles before. However, the cannon body was obviously shaking harder than before. If Yun Shu had not retreated faster just now, he would have been almost hit by the trembling cannon body.

"Ah! Brother Quan, this iron lump is really harmful to the cannon barrel." Lu Chu immediately said to Wang Gongnan in shock.

"Okay, Uncle Yun, let's put it a little bit. And, because we are rushing forward now, there are not many enemies around here, so they can't catch up with us. Then, Uncle Yun and Lu, you can fire a little less frequently. In this way, let the barrel have enough time to dissipate heat, and the iron lump will cause less damage to the barrel." Wang Gongnan immediately said to Yun Shu and Lu Chu.

"Okay." Yun Shu and Lu Chu replied in unison.

In this way, the ammunition problem of the intensive nuclear cannon was solved.

How to solve this problem? Where did the iron lumps Wang Gongnan come from?

In fact, all this was done by Wang Gongnan in the Red Purple Clothes World. When he asked Yun Shu how many beast cores and marbles there were before, Tian Shuang said that he had used one-third of the marbles. Wang Gongnan knew that if he wanted to use this cannon later, he had to find a way to get a lot of marbles and marbles.

For the beast core issue that the essence-core cannon needs to consume, this is not a problem for Wang Gongnan.

There are many forests in the Red Purple Clothes World, but basically no one is allowed to live there, and many beasts are stocked. So as long as Wang Gongnan uses his soul to issue an order to Wang Qita in the Red Purple Clothes World, Wang Qita will immediately take people to kill beasts and get the beast core.

As for the marble problem, Wang Gongnan had already thought of a way out.

Chen Yuan has now established a weapon refining group in the Red Purple Clothes World, and most of the personnel have been left in Zhangao City by Wang Gongnan to build ordinary weapons for the Wang family. Chen Yuan has led some elite personnel to explore higher weapon refining techniques in the Red Purple Clothes World.

It is easy to build ordinary weapons, but in this era of cold weapons, if anyone has enough top-quality or top-quality equipment, he can quickly gain an absolute advantage in battle. So, like some advanced weapon refiners in the world, they will not produce a piece of equipment a year or even a few years. However, as long as the one that comes out is announced to the public, it will soon be snatched by various forces in the world.

The Wang family will definitely kill the world by then, so naturally they must prepare combat equipment.

The team of combat members with the true qi fire led by Wang Yuanlie were originally the first batch of weapon refiners led by Chen Yuan. However, because these people have long-term combat experience, the most suitable combat is to fight. Therefore, these people no longer continue to learn weapon refining with Chen Yuan.

However, these people's current skills in refining are also quite good.

So, after Wang Gongnan took out a marble for the essence-core cannon and gave it to Wang Yuanlie, Wang Yuanlie immediately took people to start making it.

As for the materials used to refine this marble, it is the food iron ore prepared by Wang Gongnan for the Iron Bird.

This is done with rough processing, because after these marbles are fired by the essence-core cannon, they are basically broken by powerful impact, thus forming many shotguns flying around and hurting people.

Of course, it is necessary to have skills to make such marbles as much as possible.

Wang Yuanlie called Chen Yuan directly, and Chen Yuan asked Wang Yuanlie and others to bring a large melting pot with enough iron ore, and to a huge rock. Everyone quickly polished the rock into a large spherical shape, and made the terrain around the stone into a smooth slope. A pit was dug out at the bottom, adding water to the pit, and then poured the melted iron ore in the furnace into the rock from the air.

With a "boom", the melt spread out and the flames shone everywhere. The melt formed a ball and rolled from the stone to the slope, falling into the puddle with a "chichi".

After a while, Chen Yuan asked Wang Yuanlie and others to go to the water to salvage it, and then he took out a large pile of metal bodies of different sizes.

"Ah, here, I can't find a few of them of the same size and shape as the samples brought by the head of the family." Wang Yuanlie said to Chen Yuan in shock when he saw these metal bodies.

"To make that, you have to afford a model. The main body has to be anxious, it's too late. I have heard of the essence-core cannon, so you can try this for the head of the family first." Chen Yuan said.

"Okay." Wang Yuanlie nodded. He quickly took out a space ring, put the collected metal bodies into the space ring, and then sent a message to Wang Gongnan and asked Wang Gongnan to take out the space ring.
Chapter completed!
