The Purple Moon Palace is not small, Fang Huairan and Zhou Tong set up a retreat, took Zhu Peiying together, and flew for a while without being fast, before they arrived at the reconnaissance tower defended by the two.

According to the distance from the Purple Moon Hall to the Reconnaissance Tower, the two of them simply calculated the size of the Purple Moon Palace, which should occupy a circular area within a radius of more than ten miles.

As soon as they arrived at the reconnaissance tower, the two of them found that it was a three-story stone tower, the first floor connected to the passage to the rest of the Purple Moon Palace, the second floor was a resting place, and the third floor was a real reconnaissance place.

The two followed Zhu Peiying to the reconnaissance tower, the first and second floors are nothing special, but the third floor is quite shocking to the two, because the entire third floor has no walls except for the floor, and the floor is covered by a spherical transparent "glass" cover, which can directly see the outside moon scenery and the boundless universe in the tower.

In the middle of the floor stood a translucent, more than a person-thick, white crystal pillar with dense runes, the bottom of which was inserted into the floor, and the top of which was pierced through the top of the spherical "glass" cover, straight into the universe.

Of course, the distance between the top of the pillar and the outside of the hood is not very long, about two meters, and the end is a white translucent crystal ball the size of a watermelon.

Next to the crystal pillar, there are four white chairs in a row, and the left arm of the chair stretches out obliquely in front of the chair with a thick cross arm, and the end of the cross arm is also a crystal ball with a small head.

Looking at this arrangement with a sense of science and technology, without waiting for the two to make questions, Zhu Peiying explained: "The two uncles, the crystal pillar in the middle is the spell cannon, and the four chairs are the seats for the masters and ancestors to manipulate the spell cannon, and the spell ball in front of the chair can be used when manipulating, and the two masters and ancestors know the usage of the spell ball, right?"

Fang Huairan and Zhou Tong had already guessed that this was a fixed spell cannon and a spell ball for manipulation, but this was just a reconnaissance tower, was it necessary to use this? Zhou Tong couldn't help but ask his doubts.

Zhu Peiying replied respectfully: "Back to the senior uncle group, there is a spell cannon in the reconnaissance tower, which is only used to create time for other senior uncles to assemble and defend the tower after discovering the extraterritorial heavenly demons. ”

"How powerful is the spell cannon?" asked Fang Huairan with interest

"A normal level of the late Yuan Infant senior, if he charges up for a long time, with the power of the Purple Moon Leyline extracted from the Purple Moon Palace and the spirit stones in the palace formation, he can exert the level of a single blow from the early stage of the Transformation of the Gods. Zhu Peiying replied with a standard answer.

"A normal level of late Yuan Infant Cultivator?" the attentive Zhou Tong asked.

"Well, but the senior uncles and ancestors who can be sent to the Purple Moon Palace are all elites, and there are a very small number of senior uncles and ancestors, because of the high level of their own martial arts and their mana is very strong, if they are given enough time to charge their strength, the earth's leyline aura and spirit stones are worthless extraction, then they can all exert the level of a mid-stage cultivator who transforms into a god. Zhu Peiying explained.

"The level of the middle stage of the god formation is too exaggerated, isn't it?! This span is also too big, we used spell balls when we were in the demon realm, but it can allow the monks of the foundation building stage to exert the attack of the early stage of the foundation building, but that is because although the gap between the foundation building stage and the foundation building period is large, it is not as big as the gap between the god transformation stage and the yuan infant stage!" Fang Huairan asked in surprise.

"Is it because of the power of the lunar leylines you said?" Without waiting for Zhu Peiying to answer, Zhou Tong took the lead in guessing.

"Uncle Shi is really powerful!" Zhu Peiying patted her ass a little and continued: "Don't look at the Purple Moon, there is no spiritual energy and no air, but there are good spiritual veins underground, so the formation mages of the three factions can use the power of the leylines to provide the defense of the Purple Moon Palace and the attack of the spell cannon." ”

Zhu Peiying said this, paused, and continued with some pride: "The cannon of the reconnaissance tower is not the most powerful, and the defense tower also has a spell cannon that can combine the power of twelve late Yuan Infant monks, it is said that one cannon can have the power of the late stage of the transformation of the gods." ”

"So powerful? Twelve Yuan Infants can exert the strength of the late stage of God Transformation, plus three God Transformation Ancestors, wouldn't it be easy to kill the Extraterritorial Heavenly Demon?" Fang Huairan couldn't help but blurt out.

Zhu Peiying shook her head and said, "It's not as easy as Uncle Shi thought, after all, most of the extraterritorial heavenly demons who dare to wander around Dongyang Star are in the late stage of transforming into gods, and only a very few are in the early and middle stages of transforming gods, so every time the extraterritorial heavenly demons attack, it is a bitter battle."

Despite this, this is already much better than at the beginning of the creation of the palace, at that time, the Purple Moon Palace was generally guarded by seven or eight Transformation God Ancestors, so as to ensure that the Purple Moon Palace could stand.

It wasn't until later that it was discovered that Ziyue had aura leylines, and the power of the leylines could still be used, that the three major sects could be regarded as gaining a firm foothold on Purple Moon, and only three Avatar Ancestors and thirty-six late Yuan Infant Masters and Ancestors were stationed here.

"How long has it been since the Purple Moon Palace was created?" Zhou Tong suddenly asked.

"More than 5,000 years is less than 6,000 years. Zhu Peiying thought for a while and replied.

"By the way, why did the worst extraterritorial Heavenly Demon that appeared around Dongyang Star also have the early stage of God Transformation cultivation?" Fang Huairan asked with interest.

"According to the inference of the senior monks who came here to station, it is because the Nine Heavens Gangfeng, Sun Essence Fire and all kinds of strange light in the universe around our Dongyang Star Planet are relatively strong, and only the extraterritorial heavenly demons of the god transformation stage have the ability to approach, and the low-level extraterritorial heavenly demons will be killed by the Nine Heavens Gangfeng and others if they don't get close. Zhu Peiying replied.

"There is another thing to say, but the Nine Heavens Gangfeng does not cover the surface of the planet, why don't I feel the surroundings? and I don't feel the light of the Sun Essence Fire and the light you said?" Fang Huairan closed his eyes and sensed the surroundings when he heard this, but he didn't feel anything, so he asked in surprise.

"That's because the two senior uncles and ancestors are in the Purple Moon Palace, if the two senior uncles and ancestors leave the Purple Moon Palace alone and go outside, even if they have the protective divine light, they can't last a pillar of incense, this is the previous senior monk who personally measured it, so there will be no mistake! And there is no extraterritorial heavenly demon below the god transformation stage, which can also prove this from the side. Zhu Peiying knew a lot and replied,

"What about the Immortal Stage Ancestors? Can't they survive in the outside environment?, why can the Extraterritorial Heavenly Demons survive?" Zhou Tong asked in one breath.

"The Avatar Ancestor can hold on for a long time, but because there is no replenishment of aura, they don't dare to stay for a long time, as for why the Extraterritorial Heavenly Demons can survive in the void for a long time, it may have something to do with their race! Of course, this is all the speculation of the senior monks. Zhu Peiying replied.

"What about the Space Spirit Treasure, is it okay to hide in the Space Spirit Treasure?" Zhou Tong asked when he thought of the Heaven and Earth Xuanhuang Pagoda and the Yin Yang Gourd of the two, which could fly in the universe at the magic weapon level.
