My sister is the daughter of destiny

The next day.

"Ning Feng," Nangong Xinghuo smiled and seemed a little excited.

Lu Ningfeng attached great importance to Nangong Xinghuo and personally received him in Lucheng.

Nangong Xinghuo smiled warmly and gave Lu Ningxue his sincere blessings.

"Happy birthday, Miss Ningxue."

Then he asked Chen Jianxing, who was accompanying him, to deliver a gift.

"Thank you"

Lu Ningxue also smiled politely, nodded in thanks, and accepted the gift.

"Come on, Xinghuo, you're here at the right time. Let's go to the research institute. My cousin has already made the second version," Lu Ningfeng stepped forward enthusiastically, put his hand on Nangong Xinghuo's shoulder and took him to the direction of the research institute.

"Second edition? How come it's so fast? Did you make some revision suggestions yesterday?"

Nangong Xinghuo was extremely surprised. He trusted Lu Ningfeng's vision very much and believed that the war weapon would be fine after his inspection.

The group arrived at the Baichi Research Institute, where Ning Baichi and his team were waiting for them with big dark circles under their eyes. Without any delay, everyone went straight to the testing site.

Compared with yesterday, the new version of the war weapon has obvious changes.

The first version of the war weapon has a base that is a metal pedestal that is ten feet long and wide, and the main body is a metal block that is nearly ten feet long, wide and high.

The second version was reduced in size by half. The length, width and height of the metal cube were only about five feet. From the appearance alone, it was not much different from the first version. It was just a smaller version.

It was still a regular test firing session. The power was no different from yesterday, but the consumption of spirit stones was greatly reduced, by 90%.

Of course, the effect of reducing by 90% only works for the first time, because the war weapon had already accumulated enough spiritual energy using the spirit gathering array on the base before Lu Ningfeng and others arrived.

During the second attack, because the time interval was too short, the spirit gathering array was unable to accumulate enough spiritual energy, so it had to use the full amount of spirit stones.

Nangong Xinghuo's face showed ecstasy.

This first successful development has such power, what will happen next?

"Should we think of a way to increase its power next?" Nangong asked excitedly.

He still could not forget the blow that killed one general-level alien and injured two, and also injured the arm of a king.

That's Sweetie.

Right now it can exert the power of the Dao Entry Realm, so does it have to consider the Venerable Realm next?

"It's not that easy. The Venerable Realm is still okay. I have just reached the Dao Yuan Realm. I need to reach the Dao Yuan Realm perfection before I can try to set up a Dao Pin formation. But above the Saint level... at least there is no hope in the short term."

Ning Baichi said helplessly.

Upon hearing this, Nangong Xinghuo fell into deep thought, trying to recall the attack in his future memory.

His idea was to encourage Ning Baichi to reproduce the horrific weapon in his memory as soon as possible, so as to reduce the pressure on the Tianxu battlefield and even the battlefield outside the domain.

However, for the moment, he had no good ideas. In his previous life, he only saw a fleeting glimpse of that attack. After that, Ning Baichi died, and even the terrifying war weapon was destroyed.

"Cousin, research is important, but you shouldn't abandon your practice," Lu Ningfeng raised his eyebrows, feeling somewhat dissatisfied with this guy who was in his thirties and had just reached the initial stage of Dao Yuan Realm.

If he were an ordinary person, he would indeed be quite fast, but he was also one of the Ning family's future heirs. It would be laughable if his cultivation was too low.

"No, I have Xingyue to help me look after the research institute now. I have already found the time to break through to the Daoyuan realm," Ning Baichi said stubbornly. He naturally would not admit that he spent time practicing for a period of time just to move towards the goal of the Daopin formation.

Nangong Xinghuo on the side pondered for a long time, but still had no clue and felt a little depressed.

However, he did not get stuck in a rut. After all, he knew very well that if he wanted this war weapon to exert power above the holy level, he would have to have a holy formation to effectively kill the general-level aliens.

However, it would take a long time for Ning Baichi to improve his formation skills to the holy level, which was still a long way to go.

"Cousin, can this spiritual weapon be mass-produced? We will be heading to the Tianxu battlefield soon, and I can arrange a practical test," Lu Ningfeng asked.

"It was almost there. It was a problem with the Spirit Gathering Array. Firstly, we don't know whether the mixed spiritual energy on the battlefield will cause any negative impact. Secondly, the Spirit Gathering Array accumulates spiritual energy, but it can't preserve too much of it. Once it exceeds the upper limit of the Spirit Gathering Array, it will stop gathering. As a result, you saw it. It could only fire once and then all the energy was wasted," Ning Baichi said with a frown.

He discovered this problem when he was modifying it yesterday, but he has not found a good solution.

"The spirit gathering array is too small to hold so much spiritual energy, but the base station of this spiritual weapon is too small, so it is impossible to set up a spirit gathering array that is too large," Lu Ningfeng also frowned slightly.

After thinking for a long time without any results, Lu Ningfeng and others had no choice but to give up and treat this issue as a new research project and postpone it.

"Except for the problem with the spirit gathering formation, the others are just minor issues. They are harmless and can be modified based on the actual situation after actual combat," Ning Baichi said.

"Then let's prepare 100 new versions and 10 old versions. In case the new version is not suitable for the battlefield, we can only consider the old version model," Lu Ningfeng said and turned to look at Liuzi.

"Sixth Brother, you follow up and open two production lines. Try to get everything done in the next few days."

"Yes, son."

"By the way, cousin, I will have to go to the battlefield when the time comes. I have to observe the performance of the war spirit weapon with my own eyes so that I can know how to optimize it."

Ning Baichi suddenly said.

Hearing this, Lu Ningfeng was slightly stunned and frowned. How could a scientific researcher carry a gun to the battlefield?

But after thinking about it carefully, he realized that this guy was a cultivator in the Dao Yuan realm after all. Even if he couldn't fight, he should have no problem protecting himself, so he nodded in agreement.

"Well, the last thing is to give this war weapon a good name. It is destined to leave a mark in history books," Lu Ningfeng smiled.

After hearing this, everyone nodded in agreement.

As long as the energy problem can be solved, this war spirit weapon can almost change the battlefield situation at the Tao level! That experiment will definitely be passed down through the ages and leave a strong mark in history books.

Everyone looked at Ning Baichi. This guy was the protagonist. According to convention, this thing was named Baichi, so he couldn't escape the name.

"Why not call it Bai Chi Xing Yue?"

The girl held her little face with her twin red ponytails and laughed.

When she thought about her name being passed down through the ages along with Teacher Baili, she became extremely excited, her pretty face flushed, and she looked so adorable.

Seeing this, Xiaoxue even had the urge to hug her and rub her.

Lu Ningfeng was almost about to make the decision.

He felt that once this name came out, the relationship between his eldest cousin and Nangong Xingyue would be settled, and he could explain it to his uncle and aunt.

Ning Baichi also looked indifferent. After all, Xiao Xingyue did make a lot of contributions. Without her, his research and development journey would not have been so smooth.

However, while some were happy and some were sad, Nangong Xinghuo was the first to stand up and stared at his sister with big eyes.

"no!"

Nangong Xinghuo was really confused and looked at the girl in disbelief. Looking at her expression, could it be that she was really interested in Ning Baichi?

Nangong Xinghuo didn't dislike Ning Baichi's age, but if his father knew that he brought his little girl to the Heavenly Realm and she ran away with someone, his father would probably skin him alive when he returned.

“Why?” The girl with twin ponytails was not convinced and stared at her eldest brother with her big watery eyes.

"No..." Nangong Xinghuo was a little speechless. It was hard to say whether he was afraid of being beaten by his father when he got home. He hesitated a little, and could only act like a big brother, saying stubbornly: "No, it's not good!"

"Humph!"

The girl with twin ponytails got angry and turned her face away in dissatisfaction.

"I'm going to go back and tell Daddy that you bullied me!"

Seeing that the brother and sister were about to have a conflict, Lu Ningfeng had no choice but to step out and act as a peacemaker, and finally managed to persuade them to make peace.

As for the name of this war weapon, Lu Ningfeng had no choice but to go into battle himself and not give the brother and sister a chance to compete.

"How about calling it the Hundred-foot Heavy Cannon?" Lu Ningfeng suggested.

Xiaoxue was naturally the first one to raise her hand in approval of this name. After all, this thing was originally developed based on the setting of a cannon.

"Okay, one vote in favor and more than a dozen abstentions, that's called a hundred-foot heavy artillery."

Lu Ningfeng made the decision happily, without giving anyone a chance to react.

"Is this guy being a rogue?" Nangong Xinghuo couldn't help but complain.

"No, how can Brother Lu be as rogue as you?" The girl with twin ponytails glared at her brother with dissatisfaction, feeling upset that he rejected her proposal.

"My wife has agreed, so the matter is settled. Do you have any objection?" Lu Ningfeng spread his hands with a smile, as if to say, "I'm just going to cheat, what can you do to me?"

"Don't worry, Xiao Xingyue. I will give you some tasks in the future and let you lead the project. As long as you can do it, you can name the finished product. How about it?" Lu Ningfeng did not forget to win over the little girl with twin ponytails.

"Okay, okay."

The girl with twin ponytails immediately smiled, and did not forget to stick out her tongue and make a face at Nangong Xinghuo, looking very proud and arrogant.
