The third floor of the underground world is very wide, and the spiritual energy inside is also very rich. There are countless monsters and monsters born. The sects guarding outside the suspended bridge are all seventh-grade sect forces and families.

More than a hundred miles south of the Hanging Bridge, it is the base of Aohan Sect. Aohan Sect is a seventh-grade sect, and it is not the top-level sect. Naturally, it cannot stand at a favorable position on both sides of the Hanging Bridge. That is, a hundred miles away from the Hanging Bridge, it also has to fight with several nearby sects to seize territory.

"This is the foundation of Aohan Sect on the third level of the underground world. All you have to do is to cooperate with Senior Brother Yiying in the sect to guard this foundation." Ou Bufan said aloud to this group of disciples who have experienced it.

"We will definitely swear to defend this sect's foundation to the death." The monks couldn't help but say aloud when they heard this.

"Elder Nie, I'll leave this group of disciples to you. I'll practice it well for me to survive in this cruel environment." Ou Bufan took everyone's expressions, and then said aloud to a short and fat old man opposite.

"Everyone, you have been here for three months. During this period, you have also entered the first and second floors of the underground world. You should also understand the cruelty of the underground world. What I want to say now is that if you want to survive in this cruel world, you must abide by the orders and meet the orders and prohibitions. You must not act privately. You must report on time every day and conduct battle formation drills. At this point, everyone must cooperate with each other and not be allowed to fight in internal conflicts. Only by uniting and helping each other can you survive in a cruel environment."

In the third level of this underground world, personal force is nothing. Because the demons in this underground world are very powerful, and they must rely on battle formations to kill powerful demons.

The Aohan Sect does not occupy a very wide area. It is only a dozen miles long. There are nearly 500 cultivators stationed here, five elders in the Death Realm, nearly a hundred cultivators in the Innate Realm, and the rest are all cultivators in the Violent Qi Realm. As for the Qi Practice Cultivation Period, there is not one cultivator.

"Now you have a day off, and the battle formation drill will be carried out tomorrow." The elder surnamed Nie pointed to a row of stone houses behind the trench and said loudly at Fang Yan and the newcomers.

"This is the residence of Aohan Sect. It's really simple." Looking at the row of stone houses in front, Fang Yan couldn't help but frown. The surrounding environment was very harsh. The trenches were stained with blood and people died almost every day. There were demons from the underground world and monks.

Although the environment is harsh, this is the largest gathering place for Aohan Sect. If this defense line is lost, then Aohan Sect will fall from the top seventh-grade sect to the bottom, and this place is the top priority of the sect. Even if all the cultivators stationed here die, this cannot be lost.

When they entered the Aohan Sect's residence, Fang Yan and his team picked a stone house to settle in.

The next morning, everyone gathered together and passed the Three Talent Formation and Seven Star Dragon Lock Formation by the elders in the Death Realm.

In a group of seven, Fang Yan, Fu Qingxuan, Xia Nishang and the other three were in the same group, and the other four were all in the Brutal Aura Realm. This battle formation has to be practiced every day to hone their tacit understanding.

Mastering these two practical battle formations will give you a little bit of self-protection in this sinister underground world.

The battle formation is practiced in the morning. The afternoon is the rest time. The monks at the resident will take turns to rest every three days. During these three days, they must always stand guard at the resident defense line. On the day of rest, they can move freely, practice, or go out with others to hunt demons.

After three days of familiarizing themselves with the resident defense line, Fang Yan and the others have to be responsible for a line of defense to monitor demons that may appear at any time.

During the three days of the trial, Fang Yan and the others did not encounter any powerful demons that hit this line of defense. They practiced the battle formation every day and then practiced.

Every inner disciple has to stay here for a year, either going or staying, making his own decisions. But most people will not choose to leave. Instead, they live in Baizhan City, and whenever they have the chance, they go to this underground world to hunt demons and earn spiritual stones for cultivation.

"Fang Yan, Fu Qingxuan, and Zhang Youcai are the defense line you are responsible for. Once there is any situation, warn you immediately. As long as you persist in this battlefield for three days, you can practice freely." Xia Nishang is the captain of a small group of Fang Yan and others. He divided Fu Qingxuan, Xia Nishang and Zhang Youcai into a group.

"I understand, Senior Sister Xia, go and do your business. We will guard this line of defense." Fang Yan waved.

The defense line of Fang Yan and the other two was not very wide, only a radius of ten feet. There was a trench four or five feet long in front of it. The trench was covered with defensive formations, which could block some weak low-end monsters. The three of them guarded this area, as long as one person always observes the movements, and the other two could practice nearby.

Because Fang Yan and Fu Qingxuan are both cultivators in the late stage of the Brutal Qi Realm, Zhang Youcai is also in the Brutal Qi Realm. The three of them know each other, so Zhang Youcai was the first to warn them to warn them, and they were replaced every four hours. Fang Yan and Fu Qingxuan seized the time to practice and live, closing their eyes to rest.

"People are careful. The sentry detective in front of me heard a wave of black rats trying to hit the defense line of the suspended bridge. Please pay attention to killing these black rats as many as possible. One percent of the benefits obtained from this battle belong to you, and the other ninety percent is equivalent to the due contribution points to hand over to the sect."

An hour later, suddenly, a warning sound rang out of the trench. The elder of the Death Realm on the defense line said loudly to the monks around.

"Haha... I waited for three days, and finally it was time to harvest."

The monks on the front couldn't help laughing when they heard this, and all of them looked excited.

"Black rat, who is stronger and weaker than the Abyss Blood Wolf." Fang Yan couldn't help but look curious when he heard this.

"Black rat, the strength of the first and second level of Qi Refining Period, this third level of the underground world is the most common monster. Because the reproduction speed is too fast, they will hit the suspended bridge almost every few days. As long as these black rats do not appear, they will deliver vegetables to us at most." Wang Youcai was calm and couldn't help laughing when he heard Fang Yan's self-talking voice.

"The first and second level monsters are a little weaker." Fang Yan was thinking. What he lacked the most now is the mechanic point value used for cultivation. These black rats are weak, but they are more powerful. The mechanics and spiritual herbs accumulated before have been consumed, so he had to use some ores, spiritual medicines and spiritual herbs to exchange for successful point value to assist in cultivation.

When he came to this underground world to practice, Fang Yan also valued the proficiency and power point value of the demons. If he redeems the power point value of the redemption system, he would not be able to afford it at all. This thing is like a bottomless pit. As his cultivation becomes more and more advanced, the power point value consumed every day has reached a terrifying level. He can consume as much as he comes. Once he redeems, he will see the bottom in a few days.

"Look, there are so many black rats. Is this what you call the black rat tide? This number is really terrifying." A squeak came from a distance, and black shadows were moving quickly towards the defense line.

"Preparing for battle, this is just a low-level rat tide. If you can't use the battle formation, you can fight on your own. How much can you kill?" As the rat tide approaches, the elders of the Death Realm on the defense line issued an order to attack.
