The third level is called "Xuanwu Valley", which is a vast valley with abundant black stones. A long dam is built in the middle, and a large forbidden flight formation is on the top.

Logically speaking, the battle between the two sides is all earth immortals. The Taoist monks should go high and go high. They should fight in the air. However, the battle between immortals and demons also pay attention to step by step and advance step by step. Otherwise, they will fly directly to the immortal territory and face many immortal cultivators, no matter how high their skills are, they may be surrounded and killed!

The back of Xuanwu Valley was almost at the periphery of Lingyun Hall, so Lingyun Hall sent a large number of masters and summoned many cultivators from various sects. Even Buxu cultivators summoned tens of thousands of people, determined to defend the dam to the death and prevent the Demon Sect and the Demon Clan from rushing over.

The Four Holy Sects also responded to the call and sent thirty Taoist monks, including Jiang Yunmu and Guo Zhenjun.

Before these two people came out, they both communicated with Qin Di.

Qin Di did not have more immortal weapons, so he gave Jiang Yunmu an eighteenth-level ninth-level spiritual treasure arrow, and promoted the Overlord Bow to a sixth-level spiritual treasure.

With these spiritual treasure arrows, Jiang Yunmu can exert the power of the sunset magic arrow.

In addition, Qin Di also passed on Feng Wu Jiutian's mental method to Guo Zhenjun.

Guo Zhenjun’s purple-light heavenly fire has been promoted to the third-level immortal fire. If it is used by Fengwu Jiutian’s mind technique, it will have a great killing effect.

The thirty Taoist monks of the Four Holy Sects, led by the fifth-level earth immortal Luo Xianjing, came to Xuanwu Valley. Together with Zhuang Yunqing and others, a total of fifty monks guarded a 500-meter-long dam.

Their only mission is to defend this dam during the century.

Not only them, but other sects are the same, each sharing the defensive tasks of a piece of the dam.

As the leader of the Immortal Sect, Lingyun Palace has issued a death order, requiring each sect to complete the task! If the dam is broken through, not only will the cultivators participating in the war be detained in the water prison for 50,000 years, but the sects that have been broken through will also compensate several fairy spirit veins to those sects that fought bravely to guard the dam.

Guo Zhenjun stood on the dam and looked at the dark Demon Sect and the demon cultivators in the distance, and felt very heavy. He looked around and found that the dam defended by the Four Saints was in the middle position. The pressure here was the most and the easiest to be broken through. And once it was broken through elsewhere, they were the most likely to suffer, and they could not even escape.

He sent the news back to Xianmiao Peak and expressed his concerns.

Qin Di went down to Xianmiao Peak, came to the scene to take a look, and found that what Guo Zhenjun said was good at all.

Logically speaking, this is like the water of a big river, with the most rapid flow in the center! From a defensive perspective, the position of the Four Saints Sects is in the middle and will bear the greatest pressure, which is extremely unfavorable to the fifty monks participating in the battle!

Qin Di knew in his heart that this was also a pit dug by Lingyun Palace. In order to suppress the Four Saints, he was digging pits everywhere and repeatedly suppressing them! However, since the Four Saints Sects were assigned here, they could not directly refuse.

He walked the five hundred feet long dam and looked left and right, and found that the Tianxin Sect on the left and the Shenxiao Sect on the right, both of which were one of the seventy-two side sects. They were not very strong, but the two sects defended dams are relatively short, and each sect only had a defensive task of one hundred feet!

The heads of both sects arrived in person, looking at the enemy outside worriedly, wondering if they could defend the dam and complete the sect mission. If the task was not completed and the dam was broken, the two sects would have to pay one-third of the immortal vein, which would be a punishment that would hurt the bones.

Therefore, the leaders of both sects were worried about it. When they saw Qin Di, they hurried over to pay their respects.

Both sects have their own earthly immortals participating in the battle, but both leaders are all Taoist monks, so they are very respectful when they pay homage to Qin Di!

"Qin Xiansheng, we are asking for help!"

"In Mo Bin, there are only two Earth Immortals in our Tianxin Sect. One of them came this time, and they are only the second level of Earth Immortals. To be honest, it is difficult for us to defend this dam, so please think of a way, it is best to be able to complete the task without too many people falling. Qin Xiansheng, you are a powerful person and have great means, so you must help!"

"Qin Xiansheng, I am getting out of Ma Yu. Although there are three earth immortals in our Shenxiao Sect, one of them has just advanced and the other has entered the aging stage. Only one third-level earth immortal can really fight. Compared with the demons outside, their strength is not strong enough. Maybe after the battle, all the cultivators we participated in the battle will die!"

Qin Di shook hands one by one, exchanged greetings for a few words, and said, "A dam such a long time will definitely be broken through. I don't know who chose the defense line, how could it be so long?"

Mo Bin is a tall and thin old man, and replied in a low voice: "Qin Xiansheng, I heard that there are rumors that the four major immortals came to the door and secretly contacted the Demon Sect and the Demon Clan. The reason for launching this war was to consume a group of people! We are all the targets of being consumed!"

Qin Di was stunned when he heard this: "There is such a saying?"

Mo Bin approached a step closer: "You also know that after the Tianzhu of the Lingshan Mountain fell, not only did the fairy mountain blessed land be smashed, but the number of fairy spirit veins was also reduced. In addition to the spirit veins fixed by each sect under the main peak of the fairy mountain, all the wild fairy spirit veins were gone! I suspect that the next time the spiritual tide surged, there might no longer be spiritual veins!"

Qin Di felt aroused in his heart and thought to himself: "There are so many spiritual veins near Lingshan, some of which may be related to the ancestor witch Xing Tian. Some of them may be the sweat flowing from his body, which turned into spiritual veins underground. Xing Tian left the local area, and the surging spirit tide may really disappear."

Ma Yu is a middle-aged female cultivator with a dark face and said, "What the leader Mo said makes sense. I have also heard of this kind of rumor. The four major door-to-door visits may have reached an agreement with the demon sect and demon clan. He wants to use this battle to turn it into a meat grinder and let a large number of cultivators in the side sects fall. In this way, the remaining cultivators can obtain more spiritual veins, and have the opportunity to advance to the peak of the earth immortal, and then ascend in the sun to enter the spiritual world."

After hearing this, Qin Di couldn't help but think of the wars in his previous life. Every time when the population was too large, a large-scale war would come. For example, in the late Qin Dynasty, in just seven years, the national population dropped sharply from 29 million to 7.5 million, and a loss of 70% at once! Xiang Yu, the great hero of the Western Chu king, killed 200,000 prisoners after a war. In the first year, Wang Mang usurped the throne and restored the Han Dynasty, and the population dropped sharply from 60 million.

To 21 million. Before the Yellow Turban Rebellion, the population was 50 million, and after the Battle of Chibi, there were still 6.8 million people left. In the early years of the Yuan Dynasty, Mongolian heroes who only knew bent their bows and shot eagles wanted to turn the Central Plains into a pasture, and started killing in Sichuan, killing 20 million people to 800,000! In the late Ming and early Qing dynasties, 70 million people died in fifty years! After each war, the people were completely gone, and the land was thousands of miles away, which was not false at all.

He really didn't expect that after traveling through another world and choosing to practice immortality, he would still encounter such a thing.

Qin Di frowned and thought for a while, and said, "It's over here, two sects, what do you two have?"

Mo Bin spread his hands and said with a wry smile: "We can't think of a way, so we hope to die a few less people. Qin Xiansheng, please help."

Ma Yu took a step closer and asked, "I heard that you can refine a third-level immortal formation. Can you set up an immortal formation here to protect the areas protected by our three sects? This sect is willing to pay for spiritual crystals or immortal stones to seek protection from your sect."

Qin Di replied: "There are no spiritual veins in Xuanwu Valley. If you want to support the formation, you can only rely on the immortal stones or spiritual crystals to provide spiritual energy. In a hundred years, I don't know how many immortal stones will be spent."

Mo Bin said enthusiastically: "About the calculation, how many immortal stones are needed? I think this battle will not last too long. There must be a lot of intervals. The immortal formation only needs to be activated during the fierce battle. Our two sects are willing to bear 30% of the spiritual crystals. What do you think?"

Qin Di looked at the left and right sides again, and knew in his heart that he had to set up an immortal formation. Because even if the fifty monks of the Four Saints Sects could defend this dam, it would not be ruled out that the demon clan would break through elsewhere, and then go around and surround them. Once they surrounded them from all sides, it would be too dangerous, and I'm afraid they wouldn't even escape!

So he nodded and said, "Okay, please pay for some of the spiritual crystals first, and I'll set up the formation!"
Chapter completed!
