Qin Di returned to Luobu Immortal Mountain and placed the twenty Zhuxian cannons on multiple peaks, with the muzzles pointing in all directions.

Then, he summoned the disciples of the Four Holy Sects and drew a hundred people from them, in groups of five, to be in charge of a Immortal Cannon.

The Zhuxian cannon can convert the immortal power contained in the immortal stone into hot white light, and launch it in a straight line attack, it is not like an ordinary cannon, which is parabolic when fired, and it is somewhat difficult to operate since then, and it requires repeated training. The Zhuxian Cannon is simple to operate, easy to use, and only two people are needed to control it freely. One person is responsible for throwing fairy stones into the control mechanism, and the other person determines the direction in the scope, and then presses the mechanism button to unleash a sharp attack.

The reason why Qin Di equipped each Zhuxian Cannon with five people was because on weekdays, these disciples still had to retreat and practice from time to time, and when the enemy came to attack and the bell rang, as long as two of the five people could arrive in time, they could calmly control the Zhuxian Cannon, and the other people did not need to be forced out of the customs and interrupt the cultivation process.

After that, he handed over the task of supervising the Zhuxian Cannon to 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, and she is very senior, easy to command the disciples below.

The days passed, and ten years passed in the blink of an eye.

On this day, the Heavenly Machine Sect sent ten immortal-level arrow towers as promised.

Each arrow tower can fire a hundred third-order immortal arrows at the same time.

These immortal arrows were already full of immortal power before they were launched. After ejaculating, it can also automatically return. But it has a disadvantage, that is, it consumes too much energy, and if you want to be full of energy again, you have to wait a day. Cannot be fired in a continuous loop like low-tier turrets.

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

Many disciples gathered around to watch, pointing out with great interest.

Jiang Guanyun couldn't help but exclaim again and again when he saw the silver glittering arrow tower!

"Senior Brother Qin, what are you talking about? This is the Immortal Rank Arrow Tower? Are you mistaken? I have been in the Spirit Realm for thirty or four hundred thousand years, and this is the first time I have heard of it, and there is actually an Immortal Rank Arrow Tower! Is this a new development of the Heavenly Machine Sect?"

Qin Di smiled: "You're right. At my request, the Heavenly Machine Sect specially refined these arrow towers. I paid a lot of money to get these towers. ”

Shi Babao looked inside and outside the Arrow Tower, praised it in his mouth, and said: "The arrow towers of the three grades of the Immortal Rank, each one is worth a fortune! These ten Arrow Towers add up, a total of 1,000 Immortal Arrows! In addition, there are twenty-two fifth-order Immortal Cannons, this is too big! Xiao Qin, how many Immortal Stones have you spent? What do you want so many defensive weapons for?"

Qin Di said with a smile: "Master, I don't think the spirit world is safe, so I have to get more equipment." ”

Jiang Guanyun glanced at the Arrow Tower, and couldn't help but count: "It's too extravagant! Tut, look at it, it's just a poor and extravagant desire! It's still a third-order immortal arrow! Have you ever thought about how many third-order heavenly immortals there are in the spirit world? In my opinion, even if all the heavenly immortals howl and kill together, they won't be able to break the Luobu Immortal Mountain! With so many protective immortal weapons, how many immortal stones do they cost?"

Qin Di said with a smile: "That's right! Luobu Immortal Mountain is our home, so naturally we must do the most adequate protection, otherwise I won't be able to sleep well! Speaking of which, these arrow towers are all exchanged for immortal materials, and the cost is not too big. ”

Shi Babao asked curiously, "What kind of immortal materials do you have, where did you get them, take them out and show me." I've been refining fairy boats recently, and I have relatively high requirements for materials. ”

Qin Di took out a piece of immortal material obtained from refining stars and handed it over, this fist-sized immortal material looked very small, but it weighed more than 10,000 catties.

"Master, this thing is very heavy, you should be careful. ”

Shi Babao took it carefully, put on the Heavenly Soul glasses and looked at it carefully.

After a while, a sigh came out of his mouth, and he said, "Alas, the tyrannical destruction of heavenly things! You have suffered a big loss by making this deal! You are a third-order mid-grade immortal material, not the peak of the second order! You are also a refining immortal master, how can you be so-so? You must know that such a small piece of immortal material, added to a large amount of spiritual gold, can refine twenty arrow towers! The arrow tower is not complicated, as long as I spend a little more time, I can refine it, even if the speed of firing immortal arrows is slightly lower, but it is not much worse than the arrow tower refined by the Heavenly Machine Sect. ”

Qin Di smiled slightly: "Senior Ancestor, if you make a move to refine the Ten Arrow Towers, how long will it take?"

Shi Babao frowned slightly, and said, "No more than three thousand years! If you are a helper, it is estimated that one thousand years is enough!"

Qin Di waved his hand: "That's it." With this thousand years of hard work, I can do a lot of great things, maybe I can go to the fairy world. ”

"What? What are you talking about? You want to go to the fairy world? Don't mess around!"

After listening to Qin Di's words, not to mention Shi Babao, who had just stepped into the Spirit Immortal, even Jiang Guanyun, who was in the eighth order of the Spirit Immortal, was shocked!

Jiang Guanyun said worriedly: "I heard that the fairy world is full of immortal energy, and the immortals can't adapt to it, and if you go up rashly, you will die, you can't go!"

Qin Di lowered his head and pondered for a moment, and said, "I'm just thinking about it, and I won't put it into action easily." ”

Jiang Guanyun breathed a sigh of relief and said, "Senior brother, you have cultivated so fast, I'm afraid that in another ten thousand years, you will be able to advance to the Heavenly Immortal." Why are you in such a hurry, you want to go to the fairy world now? What is so good about the fairy world? When you really go to the fairy world one day, you are restricted there, and you can't return to the spirit world, maybe you will regret it. ”

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

He looked at the many arrow towers and Zhuxian cannons on the Immortal Mountain, and said in his heart: "With these things, it can be said that it is solid! Everything is ready, just wait for the Lingxiao Palace to come over!"

But the days passed day by day, and after two hundred years, Luo Bu Immortal Mountain was very quiet, and I don't know what the reason is, Lingxiao Hall has never come to the door. It seems that Zhang Lu's disappearance has long been completely forgotten. Luo Heng and Zhu Kun, the two immortals, were nowhere to be seen, and Ling Xiao Hall also didn't care.

Qin Di felt a little strange: "It shouldn't be! How long has it been since this happened? How could there be no movement? These three of them have disciples, maybe they also have double cultivation partners, so why don't they come out to find them? If Luo Heng and Zhu Kun are Lingxiao Hall that they joined by casual cultivation, so they are not taken seriously, then it is understandable, but how can Zhang Lu, an important figure who claims to be a descendant of the Jade Emperor, also be forgotten?"

Qin Di thought for a long time, and finally could only guess: "Either the Lingxiao Hall is loose outside and tight inside, and he is quietly investigating in private, and he has not leaked the news; or Zhang Lu likes to brag, he may be just a small person in the Lingxiao Palace, and it is not as important as he himself said! Otherwise, how could he be sent to the Primordial World to garrison for tens of thousands of years? Isn't that going to delay cultivation?"

Qin Di didn't know how wrong this guess was, since Ling Xiaodian had never come to retaliate, he didn't care about it.

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

He traveled around the major major cities nearby, and gradually came to the middle region of the Central Continent, and found that as time went by, the power of the Ling Xiao Hall became stronger and stronger, and it actually occupied one-third of the main city of the huge middle region. Originally, many sects or families living here were swallowed up by the Lingxiao Palace.
