Qin Di returned to Luobu Xianshan and placed twenty immortal cannons on multiple peaks, pointing his muzzles in all directions.

Then, he summoned the disciples of the Four Saints Sects and drew out one hundred people, five in groups, and was responsible for a cannon of Zhuxian.

The Zhuxian Cannon can convert the immortal energy contained in the immortal stone into hot white light and fire it out in a straight line attack. It is not like an ordinary cannon. It appears to be parabolic when fired. It is somewhat difficult to operate and requires repeated training. The Zhuxian Cannon is simple to operate and is easy to get started. It only takes two people to control it. One person is responsible for throwing the immortal stone into the control mechanism, the other person determines the direction in the scope, and then presses the mechanism button to launch a sharp attack.

The reason why Qin Di equipped each Zhuxian cannon with five people was because these disciples had to go into seclusion from time to time on weekdays. When the enemy attacked and the bell rang, as long as two of the five could arrive in time, they could control the Zhuxian cannon in peace. Others did not need to be forced out of seclusion and interrupt the cultivation process.

After that, he handed over the task of supervising the Zhuxian Cannon to his senior sister Jiang Guanyun.

Jiang Guanyun has hundreds of thousands of years of life experience. Whether it is skill or wisdom, she is the best choice. Moreover, her seniority is very high and it is easy to command the disciples below.

Days pass by day, and ten years pass by in a blink of an eye.

On this day, Tianji Sect sent ten immortal-level arrow towers as promised.

Each arrow tower can fire one hundred third-level immortal arrows at the same time.

These immortal arrows are already full of immortal power before being launched. After being shot, they can return automatically. However, they have one disadvantage, that is, they consume too much energy. If they want to fill up the energy again, they have to wait for a day. They cannot be launched continuously like low-level arrow towers.

Despite this, such an immortal-level arrow tower is too powerful!

Many disciples gathered around to watch and gave them enthusiastic guidance.

When Jiang Guanyun saw the silver arrow tower, he couldn't help but exclaimed repeatedly!

"Junior Brother Qin, what did you say? This is the immortal-level arrow tower? Are you wrong? I have been in the spiritual world for 300,000 to 400,000 years. This is the first time I heard that there is an immortal-level arrow tower! Is this newly developed by the Tianji Sect?"

Qin Di smiled and said, "You are right. At my request, the Tianji Sect specially refined these arrow towers. I paid a considerable price to obtain these arrow towers."

Shi Babao looked inside and outside the arrow tower, praised it, and said, "Each of the third-grade arrow tower of the immortal level is worth a lot! The ten arrow towers together have a total of one thousand immortal arrows! There are also twenty-two fifth-level immortal cannons, which is too big! Xiao Qin, how many immortal stones did you spend? What do you want so many defensive weapons for?"

Qin Di smiled and said, "Master, I think the spiritual world is not safe, so I have to get more equipment."

Jiang Guanyun looked at the arrow tower and couldn't help but scold him: "It's so extravagant! Tsk tsk, look, it's so extravagant! Or a third-level immortal arrow! Have you ever thought about how many third-level immortals there are in the spiritual world? In my opinion, even if all the immortals howled and killed them together, they can't break the Rob Fairy Mountain! How many immortal stones will it cost to have so many protective immortal weapons?"

Qin Di smiled and said, "That's right! Rob Fairy Mountain is our home, so we must take the most adequate protection, otherwise I will never sleep well! Speaking of which, I have all exchanged for these arrow towers for fairy materials, and the cost is not very large."

Shi Babao asked curiously: "What kind of fairy material do you have? Where did you get it? Take it out and show it to me. I have been refining fairy boats recently and have high requirements for materials."

Qin Di took out a piece of immortal material obtained from refining stars and handed it over. The immortal material with a fist looked very small, but it weighed more than ten thousand pounds.

"Master, this thing is very heavy, please be careful."

Shi Babao took it carefully and put on Tianhun glasses and looked at it carefully.

After a while, he sighed and said, "Oh, it's a waste of resources! You've suffered a great loss in this deal! You are a third-level mid-grade immortal material, not the peak of the second-level! You are also a weapon refining immortal master, how can you be careless? You have to know that such a small piece of immortal material can be refined into a large amount of spiritual gold! The arrow tower is not complicated. I can refine it as long as I spend more time. Even if the speed of firing immortal arrows is slightly lower, it is not much worse than the arrow tower refined by the Tianji Sect."

Qin Di smiled slightly: "Master, if you take action to refine ten arrow towers, how long will it take?"

Shi Babao frowned slightly and said, "No more than three thousand years! If you were your helper, one thousand years would probably be enough!"

Qin Di waved his hand: "Forget it. With this thousand years of hard work, I have done a lot of great things. Maybe I can go to the fairy world to visit."

"What? What did you say? Want to visit the fairy world? Stop making a fuss!"

After hearing Qin Di's words, not to mention Shi Babao, who had just stepped into the Spirit Immortal, even Jiang Guanyun, who was at the Eighth Level of Spirit Immortal, was shocked!

Jiang Guanyun said worriedly: "I heard that the fairy world is full of fairy energy, and the spirit immortal cannot adapt. If you go up rashly, you will die. You can't go!"

Qin Di lowered his head and pondered for a moment, saying, "I just thought about it and would not take action easily."

Jiang Guanyun breathed a sigh of relief and said, "Junior brother, you practice so quickly. I'm afraid you will be able to advance to the celestial immortal in ten thousand years. Why be so anxious? You want to go to the fairy world now? What's the best thing about the fairy world? When you really go to the fairy world one day, you are restricted there and cannot return to the spiritual world, you may even regret it."

Qin Di nodded: "Senior Sister, you are right. I have so many disciples and my family here. I really can't leave now."

He looked at the numerous arrow towers and Zhuxian cannons on the Immortal Mountain and thought to himself: "Only with these things can you say that they are solid! Everything is ready, just wait for Lingxiao Palace to come!"

But days passed day by day, and for the next two hundred years, Luobu Xianshan was very quiet. I don’t know why Lingxiao Palace has never come to me. It seems that Zhang Lu’s disappearance has been completely forgotten by people. Luo Heng and Zhu Kun, the two immortals, were not seen, and Lingxiao Palace also ignored it.

Qin Di felt a little strange: "No! How long has it been? How could there be no movement? These three people have disciples, and maybe they have dual cultivation partners. Can't they come out to find it? If Luo Heng and Zhu Kun are the Lingxiao Palace, which are joined by casual cultivators, and are therefore not valued, it is understandable, but why has Zhang Lu, an important figure who claims to be the descendants of the Jade Emperor, been forgotten by others?"

Qin Di thought for a long time, and finally could only guess: "Either the Lingxiao Palace is pineapple outside and tight inside, and is secretly investigating it in private, and the news is not leaked; or Zhang Lu likes to brag, he may be just a small person in Lingxiao Palace, not as important as he said! Otherwise, how could he be sent to the Yuanhuang World to stay in the Yuanhuang World for tens of thousands of years? Isn't that delaying his practice?"

Qin Di didn't know how wrong this speculation was. Since Lingxiao Palace has never come to take revenge, let's not care about it.

On this day, he explained to Jiang Guanyun and Ning Yunzhi, and then went down the mountain.
