My sister is the daughter of destiny

"This is called the Hundred-foot Heavy Cannon. This is version 1.0, the first version, and it still requires someone to control it," Lu Ningfeng said, pointing to the other three, "This is version 1.2, and it can be controlled through the Soul Mark."

"As for the consumption issue that Captain Li is concerned about, we are currently studying the use of the chaotic spiritual energy on the battlefield as energy for the formation."

As soon as these words were spoken, several elders immediately showed surprised expressions.

Even with their level of cultivation and vision, they still found this news a little unbelievable.

In the past, the chaotic spiritual energy on the battlefield was collected in large quantities and then sent out of the domain by special personnel. But now these little guys have actually come up with a powerful weapon that uses the chaotic spiritual energy as energy.

Isn't this recycling?

"only……"

"But what?" Li Yanwu didn't even notice that his tone had risen a lot.

As the commander of the Qian Army, he understood the significance of this hundred-foot heavy artillery very well.

"There are still some problems with energy," Lu Ningfeng squatted down, patted the base of the heavy artillery, and explained: "Right now we rely on the spirit gathering array to gather chaotic spiritual energy, but it takes at least an hour to gather it to launch an attack like the one just now, and it can only be accumulated once, otherwise all the spiritual energy will be used up in one go."

Lu Ningfeng pointed at the Heavy Artillery 1.0 again, "This first version uses high-grade spirit stones. Just three Dao Yuan Realm level single attacks used nine hundred high-grade spirit stones."

"Nine hundred high-grade spirit stones?"

Li Yanwu frowned. This guy is a big spender of gold.

No wonder even a famous rich young man like Lu Ningfeng has to study the use of chaotic spiritual energy. He really can't afford to waste it.

"Now that Feng'er has found the problem, do you have a strategy to solve it?"

Lu Daolin used his divine sense to scan the hundred-foot heavy artillery and understood some of its principles. The spirit gathering array was used to gather spiritual energy, but the amount of spiritual energy that could be stored in the array was limited.

"We need to ask her about this," Lu Ningfeng looked at Nangong Xingyue with an expectant smile.

Several elders also looked at the girl with twin ponytails, which made her feel a little timid.

Nangong Xingyue sorted out her thoughts and said, "We plan to refer to the purification vehicles of the military purification units and handle it according to this idea. We will prepare a large amount of chaotic spiritual energy in advance to provide spiritual energy for the heavy artillery."

"It's just that the purification vehicle is too large and needs to be improved. It would be best if it could condense the chaotic spiritual energy into liquid or solid form for easy transportation and storage."

Li Yanwu and Lu Daolin looked at each other. They were both resistant to these children's strange ideas.

Wouldn't this be a perfect complement to the Purification Troops? The Purification Troops collected a large amount of chaotic spiritual energy and used it as war supplies every time a war broke out. It was simply perfect.

"However, there are still some problems. The reason why chaotic aura is called chaotic is that it is difficult to condense into shape. The purification vehicle is large in size, but that is also a last resort. It is too difficult to liquefy chaotic aura."

Li Yanwu shook his head helplessly.

The biggest problem with the evolved troops is that they are too big and the target is too big. In addition, they can absorb a large amount of chaotic spiritual energy, so they will naturally become a thorn in the eyes of alien races and will be the focus of special attention.

"This is the problem we urgently need to solve right now," Nangong Xingyue stuck out her pink tongue a little embarrassedly. There was no other way, she didn't have any good solution at the moment.

"After the spiritual energy of the spiritual stone is absorbed, it will be broken into powder. In essence, it is neither liquid spiritual energy nor solid spiritual energy. So can we consider using some kind of stone to preserve chaotic spiritual energy?"

Ning Yushuang suddenly raised her little hand slightly and asked curiously.

As soon as these words came out, Li Yanwu first cast a strange look at her.

Could it be possible that this business queen, who had never been poor in her life, also appeared ignorant at times?

Li Yanwu wanted to complain, but when he thought about the couple's secondary professions, one was an alchemist and the other was a formation master, he immediately understood a little.

"You haven't studied how to make spirit stones, have you?"

"Can making spirit stones be as fast as I collect money?" Ning Yushuang put her hands on her hips, looking righteous.

"That's true..." Li Yanwu sighed.

"Aunt, the manufacturing of spirit stones is a century-old problem. Basically every weapon refiner has thought about overcoming this problem. Then they can just sit back and collect money," Ning Baichi explained.

"However, people only know that if the spirit vein absorbs enough spiritual energy from heaven and earth, it will produce spirit stones. But how to deal with the impurities in the spiritual energy and how to condense it into a relatively stable solid spirit stone has never been determined."

Why are spirit stones precious? It is because the spiritual energy in spirit stones is relatively pure and easy to refine compared to ordinary spiritual energy of heaven and earth, while the refining process of absorbing spiritual energy of heaven and earth is more troublesome.

"That's right..." Ning Yushuang nodded thoughtfully. She had never known such niche knowledge. After all, compared to refining weapons, she preferred refining pills and spiritual food.

But she still muttered something to show that she was not there to cause trouble.

"Isn't the spirit stone essentially a thing that holds spiritual energy? Can't we just find a replacement?"

"This is not easy. Considering the consumption of this 100-foot heavy artillery, even if there is something that can store chaotic spiritual energy, I'm afraid it will not be small in size."

Li Yanwu shook his head slightly and was about to look at Lu Daolin to ask him to control his wife and not give bad advice here to affect everyone's thinking.

However, at this moment, Lu Ningfeng suddenly had an idea and smiled, "Not necessarily, maybe this path is feasible."

Seeing her beloved son stand up to support her point of view, Ning Yushuang immediately smiled like a flower and looked at Li Yanwu proudly with an attitude of having someone to support her and feeling very confident.

Look, my son is still with me!

(*?︶?*)

Li Yanwu's mouth twitched slightly, and he decided to ignore this woman and focus his attention on Lu Ningfeng, waiting for his reply.

Lu Ningfeng gently patted the shell of the Hundred-foot Heavy Cannon and explained: "This time we are going to conduct experiments on the Hundred-foot Heavy Cannon in a battlefield environment. The experiment proves that chaotic spiritual energy will have a great impact on the core of the eye of the battle."

"So we changed our thinking and tried to replace the materials of the array's core with materials produced by alien races. These three are the final results."

"Similarly, our common methods and materials cannot preserve too much spiritual energy. Why not try the materials of alien races? Anyway, what we preserve is not pure spiritual energy, but chaotic spiritual energy."

Before Lu Ningfeng finished speaking, Ning Baichi and Nangong Xingyue's eyes lit up.

They were the only two weapon refiners present. When they tried to replace the core of the heavy artillery's formation, they discovered that in the past, they mostly used materials from the Tianlan Realm when refining weapons. They had rarely used materials from other races and knew little about them.

"This is an area worth exploring!" The girl with twin ponytails smiled, full of energy.

Before, she was worried about having no ideas, but now at least she has a research direction. No matter what the result is, she has to try it to know.

Li Yanwu did not comment on this, but looked at Lu Ningfeng thoughtfully, "I understand now. The Ning family kid was denounced as a waste by the Equipment Refiner Association, but he has achieved such results in just a few years under your leadership."

I have to say, this guy's perspective on things is quite tricky.

"That's right! Our Feng'er is the best!"

Ning Yushuang felt honored and proud of Lu Ningfeng.

"Uncle Li, there should be a lot of materials in the military camp, right?"

"Of course, just tell me what materials you want," Li Yanwu said with a smile.

"I remember that the Soul Devouring Ants, Jackals and other alien species all have the ability to devour spiritual energy. We can start from this perspective and study their characteristics of devouring spiritual energy and how they preserve spiritual energy. They may give us the answer."

Li Yanwu's eyes lit up, and he immediately made the decision, "Okay, I'll arrange a team to go out hunting and capture some aliens with the ability to devour spiritual energy. As for the materials, I'll provide enough!"

As soon as he finished speaking, he couldn't wait to set off.

"Uncle Li, please also transfer a purification vehicle over for Xiao Xingyue to do research. We are very interested in the speed at which it absorbs spiritual energy," Lu Ningfeng stopped Li Yanwu and said with a smile.

Anyway, it is something that already exists. If it can be used, use it. If it cannot be used, just use it as a reference. It is a waste of time to study something from scratch that can quickly absorb chaotic spiritual energy.

"Okay, then we'll stay in this secret place for the time being. Please wait for a moment, I'll be back soon."

Li Yanwu tore through the space and left in a hurry, leaving only Lao Lu's family and Ning Baichi, two spectators.

The old Lu couple looked at Lu Ningfeng tacitly, and the latter smiled helplessly.

"Okay, let me explain."
