Dear Lingshi

"Sir, you are so polite!" Shengyang said politely, but his hand unconsciously took the wine.

After getting the wine, Shengyang greeted a few people and began to arrange some matters for the sect. At the same time, he also began to help Lu Yunsheng refine the treasure again.

Lu Yunsheng and the other two were arranged to stay in the guest room of the Weapon Refining Sect.

"Ge Gang, Bao Hong, you two should take this opportunity to return to Fu Hu Men and arrange the relocation of Fu Hu Men. Once I finish my work here, I will come back to meet you. Then we will return to the Southern Region together!"

"Yes! Master."

"Yes! Young Master." The two of them answered in unison and left the Weapon Refining Sect directly.

"Since I've been gone for three years, I don't mind this one month."

After the two left, Lu Yunsheng muttered to himself, and began to seize the time to meditate and practice.

Time flies and twenty days have passed.

Lu Yunsheng stayed in the guest room, watching the situation inside the insect nest with interest.

After this period of reproduction, the number of soul-eating insects in the insect nest has increased from only four to about one thousand.

Just an hour ago, Lu Yunsheng threw a low-grade spirit stone into it. Who would have thought that after only an hour, the spirit stone was almost completely eaten by the spirit-eating insects.

Lu Yunsheng felt both happy and worried. He was happy because he found through observation that after the Soul-Eating Insect's last advancement, its eating speed had reached eight times its previous speed.

Seeing this situation, Lu Yunsheng felt that these soul-eating insects might be able to achieve great things in the future.

What worries me is that if these soul-eating insects continue to reproduce, once their numbers increase, my spirit stones may be in danger.

As a businessman, Lu Yunsheng had already done the math in his mind. With the current one thousand soul-eating insects, they would eat eight low-grade spirit stones a day, which means two hundred and forty a month.

It may seem like a small number now, but if they continue to multiply, it won’t be long before the number of these insects reaches one million, and the spirit stones consumed in a month will reach 240,000 low-grade spirit stones.

You have to know that the more insects there are, the faster they reproduce will increase exponentially.

The actual consumption by then will definitely be more than what is calculated now.

"I hope you won't let me down in the future." Lu Yunsheng muttered to himself as he took out tens of thousands of low-grade spirit stones and threw them into the insect nest.

Now that these insects' appetites have increased greatly, he also feeds them enough food at one time to avoid the insects devouring each other if he forgets to feed them when something happens.

After taking care of the soul-eating insect, Lu Yunsheng began to practice again.

Ten days passed in a flash.

"Knock knock knock!" That morning, Lu Yunsheng's practice was interrupted by a series of knocks on the door.

When he opened the door, a disciple from the Weapon Refining Sect was standing in front of it.

"Senior, the ancestor invites you!" When the man saw Lu Yunsheng open the door, he said to him respectfully.

Upon hearing this, Lu Yunsheng naturally knew that the one-month period had expired. He was delighted and quickly followed the disciple out.

At this time, Shengyang was standing in his own refining room, looking at the four glowing treasures in front of him with a look of satisfaction on his face.

"Master, Master Lu has been brought here."

At this time, a voice came from outside the door.

Upon hearing this, Shengyang hurried forward and opened the door.

"Sir, I have lived up to your expectations. The four treasures have been refined." Shengyang said as he pulled Lu Yunsheng into the house.

When Lu Yunsheng entered the room, he did not look at his treasures. Instead, he was attracted by the rows of tall storage racks in front of him. At this time, these storage racks were filled with various treasures and some semi-finished magic weapons that had not yet been refined.

"Sir, take a look and see if you are satisfied!"

After hearing Shengyang's reminder, Lu Yunsheng shifted his attention to the golden flying sword that Shengyang handed to him.

Lu Yunsheng slowly took it in his hand. At this time, the appearance of this natal flying sword was still the same as before, golden in color and three inches long, but it was several points lighter than before.

Another change was that the aura became more restrained. Lu Yunsheng looked at it carefully for a moment, but did not detect any sharpness from the flying sword.

"Young Master, come and try!" Shengyang summoned the Four-phase Spirit Shield and said to Lu Yunsheng.

"Okay!" Lu Yunsheng couldn't figure out the reason and agreed immediately.

Since this was indoors, Lu Yunsheng did not use the Ten Thousand Silk Tribulations, but instead endowed the sword with sword power and immediately stabbed towards the Four-phase Imperial Spirit Shield.

After this stab, Lu Yunsheng found that the speed of his natal flying sword increased a lot, and the connection with him became closer.

"Bah!"

A sound was heard, and Lu Yunsheng looked carefully, only to see that half of the flying sword had directly penetrated into the Four-phase Imperial Spirit Shield.

This Four-phase Imperial Spirit Shield is a top-grade magic weapon! A month ago, I tried my best but didn't cause any damage to it.

Seeing this, Lu Yunsheng hurriedly recalled the flying sword, held it in his hand and looked at it lovingly, feeling surprised and happy.

Seeing Lu Yunsheng's satisfied look, Shengyang smiled and continued, "Sir, this flying sword is your natal flying sword after all. I dare not interfere too much. I can only refine it into the level of a low-grade magic weapon. Next, you need to break through the Nascent Soul stage and slowly cultivate it yourself."

Upon hearing this, Lu Yunsheng hurriedly thanked him.

"You're welcome, sir. Let's take a look at these treasures. The foundation of this Mountain-Crossing Seal is pretty good. It has already reached the level of a magic weapon. I have added some precious minerals to refine it into a mid-grade defensive magic weapon - the Mountain-Crossing Sea Seal." Shengyang said as he took the Mountain-Crossing Seal, which had been transformed.

At this time, lines of mountains and seas intersecting appeared on the seal, and the color looked even deeper. Lu Yunsheng held it in his hands and felt the heavy breath coming from this small seal. He was so happy.

He thought that this small seal could be refined into a low-grade magic weapon, but he didn't expect that Shengyang could directly refine it into a medium-grade magic weapon.

Before Lu Yunsheng could say thank you, Shengyang took the cracked black tortoise blue crystal ring.

"Sir, this treasure was already damaged, so there is little point in repairing it. I had no choice but to recast it and add some precious ore into it, but I only refined it into a low-grade magic weapon. If you give me another half a month, I will definitely be able to upgrade it to a mid-grade magic weapon."

Lu Yunsheng looked at the new Xuanwu Qingjing Ring that was ablaze with precious light. He was very satisfied and said to it quickly: "No need! No need!"

After hearing this, Shengyang showed a trace of regret on his face, and had no choice but to hand over the pair of Cloud-Stepping Shoes that had also been transformed.

"Although this pair of Cloud-Walking Shoes was originally only a top-grade spiritual weapon, after I added some cloud silk and other spiritual materials, it has fortunately become a lower-grade magic weapon."
