Feng Shao felt the care of a family member from Lin Fengtian's words just now, which touched him deeply. He nodded solemnly and said, "Please rest assured, father-in-law!"

Lin Fengtian laughed, patted his shoulder vigorously, and said, "A Shao, stay for dinner later! There won't be anyone else, just our family of four!"

"Okay!" Feng Shao said with a smile.

Although Feng Shao had eaten with Lin Fengtian and Xiao Ruoyao before, there were many other people present at those times. This time, it was a real family dinner. Although there were only four people, there was a special feeling of warmth.

At this family dinner, Lin Fengtian and Xiao Ruoyao did not talk about any official business, but talked about some interesting things about Lin Xiaoran's childhood, which made Lin Xiaoran very shy and couldn't help but quarrel with his parents. Feng Shao watched this scene with a smile, and there was a trace of warmth in his eyes.

It’s such a good feeling to be at home!

That night, Feng Shao and Lin Xiaoran stayed overnight and returned to Xincheng the next day.

After returning to Xincheng, Lin Xiaoran followed Xiao Ruoyao's instructions and began to take care of the baby. In order to avoid stimulating the fetus, Lin Xiaoran put aside almost all his cultivation except for the necessary meditation and breathing. When Luo Qiushuang and others learned that Lin Xiaoran was pregnant, they were all surprised. It was hard to believe that the master who had always been steady would be so informal.

But in the final analysis, everyone was happy for the two of them from the bottom of their hearts, and even started discussing privately whether they would have an additional junior brother or a junior sister in the future.

Or multiple junior brothers and sisters at the same time?

In short, everyone in the new city is in high spirits, which brings some joy to this spring.

As one of the main parties involved, Feng Shao, in addition to feeling the joy of becoming a father, also felt a heavy pressure.

When he was in Taiwei Sect, Feng Shao devoted himself to it and worked hard for it. After he left Taiwei Sect, Feng Shao began to plan for himself.

But now, Feng Shao not only has to consider himself, but also his wife and children, and his family.

Feng Shao's most important reliance at the moment is Yunjian Pavilion, but in the final analysis, the power that truly belongs to him should be Wuling City. Therefore, the focus of his next work will still be the construction of Wuling City.

After returning from Mount Taiwei, Feng Shao began to study natural spiritual energy while building Wuling City. This small sum was one of the results of his research.

Oh, by the way, now this small pen has been renamed "Carving Array Pen" at Xiao Ruoyao's suggestion.

Natural spiritual energy is very different from spiritual stones after all. Its unique properties and versatility reveal that it has a broad prospect for use. Feng Shao first studied the application of natural spiritual energy in manufacturing.

Feng Shao's original plan was to design an ink pad like a movable type printing press, infuse natural spiritual energy into it, and then produce formation diagrams in large quantities.

Simply put, it is to make an ink pad with a formation diagram engraved on it, and then use natural spiritual energy as ink, and press it directly on the medium, and a formation diagram will appear. According to Feng Shao's expectation, such an ink pad can produce a large number of formation diagrams, and the application range of formation diagrams is very wide. Just by selling formation diagrams, Feng Shao can make a fortune.

However, after the experiment, Feng Shao helplessly discovered that the array diagram that only infused the true qi without the mental power was soulless and would not have any effect at all. The complexity of the array diagram also determined that the infusion of mental power had to be done slowly and could not be done in one go, so it was not feasible to infuse mental power while printing the array diagram.

In order to solve this problem, Feng Shao must first thoroughly study the nature of mental power.

However, due to limited energy, Feng Shao did not have time to study mental power too much, so he had to settle for the next best thing and developed the engraving pen.

However, although it is a second-best product, its application prospects are already very impressive.

Not long after, Xue Li, the head of the Fire Refining Hall of Yunjian Pavilion, came to Wuling City with a dozen of his disciples. His purpose of coming here was to learn how to make the formation pen from Feng Shao.

As soon as he saw Feng Shao, Xue Li was full of praise: "My dear, I didn't expect that you have made such an amazing thing after just a few months of not seeing you! Don't you really want to consider learning how to refine weapons from me?"

Feng Shao waved his hands and said, "Master Xue, you are too kind. I was lucky to make the engraving pen. I don't have much talent in refining tools, so I won't waste my time on this."

Xue Li shook his head with some regret: "What a pity. If you learn to refine weapons, I'm afraid it won't take long for you to become a leading master of refinement!"

Feng Shao smiled and said, "Okay, Master Xue, there is no need to say more. Before coming here, my father-in-law should have explained everything to you clearly, right?"

Speaking of business, Xue Li also said seriously: "The Pavilion Master said that although your engraving pen has extraordinary effects, the output is too low, so he asked me to bring my disciples here to learn how to make the engraving pen from you."

Feng Shao nodded: "In that case, please follow me!"

Feng Shao brought everyone to his laboratory and explained the principle of the engraving array pen to everyone. Everyone present had a good eye for refining equipment, and after just understanding the principle, many wonderful ideas came to their minds, and they couldn't wait to put their ideas into practice.

Feng Shao knew that "it is better to teach people how to fish than to give them fish", so he only explained the principle of the engraving pen and did not tell everyone the specific production process of the engraving pen. I guess with their abilities, they can definitely design a better engraving pen, right?

As the most experienced weapon refiner, Xue Li immediately discovered the key.

He pointed at the storage ring on the table and asked, "The concentrated spiritual energy in here is probably not that easy to obtain, right? I have thought about compressing the spiritual energy before, but I couldn't do it. How did you achieve it?"

Feng Shao said with a smile: "Master Xue, have you forgotten the spiritual energy mine we mined? The spiritual energy that comes out of the spiritual energy mine is all this compressed spiritual energy!"

Xue Li couldn't help but take a deep breath. Such high-quality concentrated spiritual energy is actually natural? Then Feng Shao really picked up a treasure!

Then, Xue Li realized how precious the value of this concentrated spiritual energy was!

As we all know, there is spiritual energy between heaven and earth, but it is extremely thin. Some high mountains and famous rivers have relatively strong spiritual energy, which has been regarded as holy places for cultivation, and has been fought over by major forces. What does this concentrated spiritual energy mean? It means that such holy places for cultivation can be easily mass-produced!

Let's talk about the present first. Wuling City is located in a place with thin spiritual energy and no rare specialties. It is not suitable for building a city and it is difficult to attract monks. But if there is this concentrated spiritual energy, as long as it is diluted to a certain degree, it can cover the entire city and turn it into a holy place for cultivation.

In addition, one can also build spirit gathering towers, trial fields, city defense formations, medicine gardens, spirit beast farms, etc. If other sects want to build these things, the spirit stones consumed would be in the millions!

Thinking about it this way, how could Wuling City be a place with little spiritual energy? It was clearly a place blessed by nature!

Feng Shao saw what Xue Li was thinking, and said with a smile: "Master Xue must have thought of the wide range of uses of this concentrated spiritual energy, right? Now the city defense formation has been completed, the Spirit Gathering Tower and the Trial Field are under construction, and the medicine garden is still being cultivated. It won't be long before Wuling City will become a famous city far and wide!"

When talking about his ideas, Feng Shao was full of passion and imposing manner.

Xue Li looked at Feng Shao's confident face, while thinking of other ideas in his mind.

Or... I might as well just move the Fire Refining Hall here?

You know, the most important thing for refining weapons is spiritual fire. And with spiritual fire, a large amount of spiritual energy and spiritual stones are needed to maintain it. With natural spiritual energy, the quality of the flame will be improved? The flame will rise up? The black iron ore that originally needed three days to be completely melted would probably take more than three hours here?

When Xue Li thought of this, he became itchy and wanted to build a foundry here immediately.

Afterwards, under Feng Shao's arrangement, Xue Li and his disciples temporarily settled in Wuling City. Xue Li wrote a letter to Yunjian Pavilion that night, asking Lin Fengtian to move the headquarters of Huoliantang to Wuling City.

The next day, Lin Fengtian's reply arrived, and the person who brought the letter was Jia Chan, the head of Qingxing Hall.

Lin Fengtian not only agreed to Xue Li's request, but also ordered Jia Chan to move Qingxing Hall here as well. In his letter, he said frankly that during their stay in Wuling City, everyone in Huolian Hall and Qingxing Hall must obey Feng Shao's orders. Feng Shao was responsible for all the affairs of Huolian Hall and Qingxing Hall in Wuling City.

Lin Fengtian was announcing to everyone that in Wuling City, Feng Shao's status was equivalent to that of the master of Yunjian Pavilion.

Looking at the contents of the letter, Xue Li couldn't help but sigh. The Pavilion Master really treats Feng Shao as his own son!
