"Senior brother has a very good idea. The underworld is a vicious place. They even want to invade the Immortal World. Moreover, this world is very large and has a vast territory. Even if we try our best now, we may not be able to activate the interface power of the Immortal World. Just like the interface power of the Immortal World, we are also difficult to activate unless it is a saint-level existence."

Qingfeng pondered for a while before slowly taking Li Mubai's words. He thought that Li Mubai was very considerate. The method of three-person attack not only condensed the power of the three people, but also increased the methods exponentially, but also allowed to take care of each other.

"Of the three of us, only Senior Brother Tiandu has been to the underworld. Senior Brother Tiandu, please introduce this interface to us and make us ready."

Mingyue took a sip of wine, her face turned slightly red and a hint of excitement before she spoke.

Li Mubai nodded and said slowly:

"The danger level of the underworld is far greater than that of the magic world in the human world. Any place can almost be compared to the dangerous places like Nuwa Tomb. Moreover, the underworld is always dark and without daytime. However, there are two huge moons. There are very few green spaces there. Even if there are, they are gloomy and full of dangers... The most common in the underworld is the only one in the underworld. The underworld is also one of the few creatures with flesh and blood. There are not many species of them, but they all have strong combat power. Unlike monsters, they are similar to the ferocious beasts of the ancient times."

"Ah...and there is such a thing?!"

Mingyue put down the wine glass, and the wine became much more awake, and his expression became very ugly.

"Senior Brother Tiandu, you went to the underworld and only entered the Taiqing Palace before entering the Taiqing Palace. Over the years and years, it is impossible for the underworld beasts to be many."

Qingfeng pursed his lips and asked softly with a hint of luck.

Li Mubai shook his head, stared at the distance with a little hollow, and murmured:

"This may be the case that the underworld is not here. There are battles everywhere. It is a world where the strong prey on the weak. Only with endless battles can species truly evolve, and it is also possible that these underworld beasts have become extremely powerful."

After saying this, the surroundings became quiet again. Qingfeng and Mingyue did not speak anymore. Instead, they were thinking about what Li Mubai said. If he really speculated according to his own way, those dark beasts would likely become stronger. Just like those undead, as long as they could absorb the fire of the undead, they could evolve again. There was only a little bit of strengthening, no reason for degradation.

"Senior brother has figured out our joint attack technique."

After a long time, Qingfeng slowly spoke.

"How about the Qinglian Sword Formation?"

Li Mubai did not hesitate at all, because after he came out of the bedroom, he saw Qingfeng and Mingyue joining together to perform this powerful sword formation. In fact, he would also use this sword formation. It was just a matter of idle trouble, and the power of one person was limited, but the three people joined forces was different. This is a rare combined sword formation, and it is also the upper secret technique in the secret method of Taiqing Palace. More importantly, he is now the bone of the sword spirit, which can make the power of the sword formation a higher level.

In addition, there is another important reason, that is, no matter whether the other party is a physical or an illusory body, it can be cut. This is the best point, because many undead creatures do not have entities.

"The Qinglian Sword Formation is not the most powerful secret technique of joint attack, but it is very convenient to drive it at our level. It's okay, but this sword formation does not seem to need to be adjusted. It was originally a secret technique that the three of us were proficient in. What are the plans for this year, my senior brother?"

Qingfeng thought about it and asked again.

"I plan to continue to practice the power of Hunyuan, because I still have several powerful secret techniques that require the power of Hunyuan to practice. When you reach the underworld, the spiritual energy will definitely become very thin. At that time, every time we cast a secret technique, it will consume our magic power. The recovery will not be that simple at that time. No matter which interface the power of Hunyuan is located, it can absorb the surrounding energy and convert its own magic power."

Li Mubai smiled slightly, and his face showed strong confidence.

In the following time, the three of them began to go into seclusion at the same time.

The things about Emperor Wa really fell on Elder Miaoxue. Li Mubai had even given instructions on what happened in the future. If he left the Palace of Imperial Palace, Miaoxue would take charge of the Palace of Imperial Palace.

For those who practice Taoism, a year is nothing, it’s just a blink of an eye.

Of course, Li Mubai did not really go into seclusion for a year. During this year, he went to Tianfa Peak to meet Na Sheng several times. The two of them stayed on the mountain for a long time. Of course, love is also essential. He also went to Wanjianmen once. Wanjianmen has been well built and has waved to many disciples from the magic world.

Li Mubai arrived at the Wa Palace one day earlier than a year.

On the day that was agreed, Mingluo and Mingxue arrived. Although Mingluo did not change much, his complexion was much better than a year ago. Especially the dark talisman in his eyebrows looked even more strange, while the dark blood next to him had not changed. It was still the same as before. He wore a golden mask on his face and stood by Mingluo without saying a word, acting as a personal guard.

Li Mubai also guessed that the true identity of Mingxue was, but because of the mask on her face, she could not see her true face clearly.

However, Qingfeng and Mingyue did not come out of seclusion. It was not until the sunrise the next day that the two brothers arrived late, but they both looked proud. It seemed that they had made a lot of effort during the seclusion this year.

"Sorry, let my senior brother wait for a long time."

Qingfeng walked over and gave a gift.

"It's okay, let's set off to the underworld. During this year, Di Ksitigarbha's reincarnation has arrived at the Netherworld Blood Sea. I think we should be ready now, are you ready?"

Li Mubai glanced around and spoke in a low voice.

“It’s ready.”

Qingfeng and Mingyue spoke in the same voice, while Mingluo nodded.

Li Mubai reached out to the land beneath him, and a huge golden talisman flashed out. The light of the golden talisman condensed and completely penetrated into the soil. Then a huge golden vortex appeared, and there was still a trace of black mist in the vortex. Li Mubai jumped and his body disappeared into the vortex. Qingfeng and Mingyue jumped down with him. Ming Luo looked up and found that the black fog was strong in the vortex. He could not see clearly where the passage was ahead, but he still gritted his teeth and jumped down.

A golden vortex suddenly appeared on a mountain in the Netherworld Blood Sea. The vortex appeared quietly, and a figure flew down inside and landed steadily on the ground.

As soon as the golden vortex appeared, it alarmed the evil ghosts around them. They were all imprisoned in the Netherworld Blood Sea. Although they were not in the Blood Sea, they could not leave this place. Now a golden vortex appeared on the hill and could lead to another place. These evil ghosts naturally flocked to them.

Li Mubai had just landed on the ground. Before he could recover, a strong smell of blood immediately spread around him. Then the wind blew, and the shrill sound of ghosts came from afar. As soon as he opened his eyes, he saw some evil ghosts stretching out their ghost claws and grabbing them on him.

They came down, not by their souls, but by their body. Therefore, these evil ghosts could smell the smell of strangers, so they wanted to share Li Mubai's flesh and blood and increase their abilities.

A trace of anger appeared on Li Mubai's face. He waved his hand and a green light shot out. As soon as these green lights were shot out, they turned into green light swords and slashed around.

Angry screams rang out in a harsh voice, and the screams immediately turned into a howl.

The surrounding ghosts were directly slashed into ashes by the blue sword light, but the situation was not effectively controlled, and there were still many ghosts rushing up below.

Li Mubai's face became a little gloomy. Just as he was about to use the soul-summoning lamp to burn the surrounding ghosts all in one go, a roar suddenly sounded from afar.

The roar rolled in from the blood-red horizon like thunder. Li Mubai was slightly stunned. When the ghosts around him heard the loud roar, they all fled in all directions. Before the roar fell, the evil ghosts around Li Mubai had already escaped completely.

At this time, the breeze and bright moon set in the vortex. After a while, Ming Luo and Ming Blood also fell. The golden vortex began to slowly disappear, and finally calm returned to the void.

However, the nearly beast-like roar in the distance became louder and louder, and finally the sound stopped abruptly. A giant beast as dark as ink, like a unicorn, arrived near this mountain.

Ming Luo's face changed slightly, and when he pinched his hands, a gray glow appeared all over his body, and a trace of black electric arc appeared among these gray glows and twisted.

"Listen carefully?"

Ming Xue let out a soft and inaudible whisper from his mouth.

At this time, Ming Luo took action, raised his hand and waved it, and a gray mist shot out in an arc. Li Mubai next to him frowned, and a group of people with one hand was empty. A dazzling blue sword light appeared on the gray mist and slashed down hard.

"Boom!"

The blue sword light exploded, colliding with the gray mist, and at the same time turned into energy and dissipated around.

The black giant beast's big copper bell stared at Mingluo, then stared at Li Mubai, and its huge body jumped forward, and its black light lingered all over its body, turning into a little black cat and landing on Li Mubai's shoulder. Then it stretched out its pink tongue and licked Li Mubai's cheeks, looking very docile.

The people around him were stunned and did not recover for a long time.

"Yin Si, stop being naughty."

Li Mubai looked at the little black cat rubbing around his neck and rubbed his head with a smile.

The little black cat stared at Li Mubai with green eyes, then jumped off him and turned into a boy in black clothes. The boy was not very tall, his skin was pale, his eyes were like emeralds, and his mouth was smiling at Li Mubai, and he said:

"I knew you were here, so I ran over to greet you. The evil ghosts just now just wanted to escape from here, and it happened that you were from the body again, and they were stained with the breath of living people, so they were so crazy."
