In addition to the Yin Yang Dragon Gate Array, Yu Fei quickly arranged another Qiankun Divine Thunder Array, two main formations, enough to cover a quarter of the area of the City Lord's Mansion. Yu Fei has left a mark on Luo Yin and Luo Fan's soul power, in addition to Yu Fei, Luo Yin and Luo Fan can also urge the two main formations.

"Yu Fei, give the mark of controlling the two main formations to the city lord. Luo Fan said to Yu Fei with a wry smile, after all, Luo Muyun is the lord of the City Lord's Mansion.

"Hmph, leave it to him, that guy who doesn't talk much! Don't even think about it unless he comes to beg me!" Yu Fei snorted, he was really competing with Luo Muyun.

Luo Fan knew that it was not so easy to reconcile Yu Fei and Luo Muyun, how should this matter be resolved? Luo Fan was also a little distressed. Although he knew that it was impossible for Luo Muyun to pull down his face and beg Yu Fei, since he had received an answer from Yu Fei, he could at least go back and make an errand.

After Luo Fan left, Yu Fei continued to practice in the courtyard.

The night was getting deeper.

The entire City Lord's Mansion fell into a deep silence, except for the occasional footsteps of patrolling guards and the sound of birds fluttering by.

Yu Fei was running the Heavenly Dao, swallowing soul power, only to see that in the night, a stream of breath was like a whirlpool, and it was swept into Yu Fei's body. The progress of Yu Fei's cultivation is simply amazing.

At this time, Yu Fei seemed to blend into the deep dark night.

At this time, in some corners of the City Lord's Mansion, figures suddenly appeared, each of them wearing black clothes, completely hidden in the darkness.

"Have you found out, what are those giant pillars for?"

"It's not clear yet, but I know that a young man urged the giant pillar and then knocked Luo Muyun down. ”

"How is it possible for a young man to urge those giant pillars to defeat Luo Muyun, a legendary-level martial artist?"

"I saw it with my own eyes!"

"No wonder the General sent us over to test the City Lord's Mansion. ”

"With the strength of our Vermilion Bird Country's frontline, as well as some extraordinary means at our disposal, it is not difficult to destroy this Blue Dragon Country's Western Regions, why is the king reluctant to do it. ”

"It's not difficult to destroy the first line of the Western Regions of the Qinglong Kingdom? You also underestimate the nine major fortresses of the Western Regions of the Qinglong Kingdom! After all, the Luo Shen family and the Qilin family have been inherited for so many years, how can they not have some means? The brave iron horses on the front line of the Western Regions are as many as 300,000! Moreover, there is the strong support of the Wendao, Bing Xue, and other families! When it is really time for war, the strength they have erupted from them should not be underestimated! This time, the seven of us led people to attack the City Lord's Mansion of Luo Shen City, and you must also be extremely careful, and you must not be careless!" The man in black in the lead snorted coldly, "In addition to destroying that formation, you must capture that kid alive!"

"Big brother, look at it, with the strength of the seven of us, even if there are a few star-level martial artists in the City Lord's Mansion, they will not want to stop us. ”

The seven men in black fused with martial spirits, and their bodies were constantly changing, and the nightmare black fox, saber-toothed tiger, honey badger, ancient python, phantom shadow, white bear, and ice worm, after these characteristics appeared on their bodies, they all disappeared in the darkness.

At this time, there is an open space in the south of the City Lord's Mansion, this is the weakest area of the City Lord's Mansion's defense, and it is the martial arts arena of the City Lord's Mansion.

At this moment, sixteen people wearing black cloaks were surrounding each other, and an area of more than ten meters in which complex runes were being carved.

These runes shone with an eerie blue glow that stood out in the dark.

In the middle of the rune is a scroll that resembles a summoning scroll!

Sixteen people muttered complex incantations, and the runes on the ground lit up one by one, more and more.

At this moment, five patrolling guards approached, and they passed through the corridor in the distance, and when they noticed the bright blue light here, they came to inquire about it.

"Who are you, what are you doing here?" The five guards in charge of patrolling were too alert, in their opinion, the City Lord's Mansion was an absolutely safe place, who would dare to make trouble in the City Lord's Mansion?

At this moment, five figures suddenly appeared behind them, poof, blood splattering.

These five guards were only silver-level, and the people who assassinated them were at least platinum-level existences, and they were caught off guard, and before they could even make a sound, they fell into a pool of blood.

The sixteen men were still muttering incantations as if nothing had happened.

The scroll turned into a golden light under the condensation of blue rune light, bombarding the ground!

Thundered.

The ground is cracking!

"Come out, Demon Dragon!" one of its leaders shouted in an almost frantic voice, the faint blue light shining on his face, making his face look particularly hideous.

This demon dragon is sealed underground, and this scroll similar to a summoning scroll is called the Unsealing Scroll, which is the key to unlocking the seal of the underground demon dragon!

The gray robes of the sixteen black-clothed people were windless, and the whole person slowly floated out of thin air.

Boom Boom!

The martial arts arena continued to crack, faintly, the ground seemed to emerge hot red magma, a huge black dragon head, from the fiery magma continued to rise, magma rolled, a lot of small magma splashed on the ground in the distance, after landing suddenly turned into a small fire demon, these little fire demons screamed, impacting in all directions, wherever they went, the ground was burning.

A huge demon dragon tens of meters tall rose from the magma, its whole body black, as if it had passed a layer of black armor, and it had giant wings on its back.

"Hahaha, wreak havoc, Demon Dragon!" the leading man in black laughed wildly.

At this time, the demon dragon suddenly opened its eyes like copper bells, and the blue demon fire in the dragon's mouth slammed forward, and the leading man in black was instantly annihilated in the flames, and he didn't even let out a scream.

When the remaining fifteen men in black saw this scene, they were immediately frightened and hurriedly ran outside.

After this demonic dragon was summoned, there was no enemy or enemy at all, as long as it was something in front of it, it would not hesitate to kill it!

Boom Boom!

The flames were blazing, and the south of the City Lord's Mansion was completely plunged into terrible chaos.

At this time, Yu Fei, who was cultivating in the Luoyin Courtyard, suddenly opened his eyes after feeling the movement in the south, and looked towards the south of the City Lord's Mansion, where the flames were shining and the shouts shook the sky, obviously caught in a big battle.

Yu Fei's heart sank, someone attacked the City Lord's Mansion of Roselle City? And made such a big move?

"Yu Fei, what happened?" Luo Yin swept out of the attic, and when he saw the fiery scene in the distance, he was shocked, the City Lord's Mansion had been attacked?

Yu Fei frowned slightly, in his previous life, until he rebelled, there had never been an attack on the City Lord's Mansion of Roselle City, it seems that after he was reborn, some butterfly effects were triggered, which led to this incident.

The south of the City Lord's Mansion is the weakest area to defend, but it is also the least important place, and there is no point in attacking there!

The only explanation is that this is the enemy's ploy to attack the west!

They wanted to attack the south side of the Lord's Mansion to attract the attention of the guards.

So the real goal is ......

Yu Fei's eyes flashed, the other party's target was undoubtedly him! The talent he had shown during this time was enough to attract the attention of some people in the Vermilion Bird Country, in addition to them, the Sword Immortal Family also didn't want to put him to death all the time!

"Hmph, I didn't expect that the Vermilion Bird Kingdom would really be willing to spend the money, and he would not hesitate to send someone to infiltrate Roselle City and attack the City Lord's Mansion to arrest me!" Yu Fei thought to himself, glanced at Luo Yin and Yu Xin next to him, and said in a deep voice, "Luo Yin, you take Yu Xin to the secret room to hide!"

"No!" Luo Yin said resolutely, the City Lord's Mansion was attacked, how could she be completely indifferent?

"You're only one golden star, you can't be the opponent of those people!"

"What about you?" Luo Yin said anxiously.

"They are coming for me, but I have the means to save my life, I will lead them to the Yin-Yang Dragon Gate Array and the Qiankun Divine Thunder Array, and try to kill a few!" Yu Fei smiled slightly, "During this time, you should also know the power of the Yin-Yang Dragon Gate Array and the Qiankun Divine Thunder Array, even your father was beaten down by me!"

Luo Yin was silent.
