The blood enchantment was finally completed. The two white tigers that were guarding outside the enchantment with black stripes on their heads nodded, "Rest assured! We will definitely protect her, so you can rest assured! "

Li Yun and Lian Chengxue walked in, followed by a group of horse riders from the opposite room who opened the door as well. They bid farewell to Xiang Xue and wondered what kind of battle the Underground City was going to welcome them with as they headed in that direction.

However, when they reached the entrance of the underground city, the door did not open as usual. It was likely that Holy Lord Black Dragon had already sensed the danger and shut the city gates tightly.

The horse stared at the waterfall, turned his head and asked, "Could it be that this underground city is right behind this waterfall?"

"Yes!" Li Yun took a step forward and walked under the waterfall. Raising his head to look at the untouched door, he sneered. "Since you won't open the door for us, then we'll open it ourselves!"

As he finished speaking, he took out the Azure Dragon Sword from his back and held it tightly in both hands, taking a deep breath as he gathered his Qi into his Dantian. He then shouted out loud and raised the sword in his hand, only to see that the sword was surrounded by a strong sword qi.

"Exorcist Upanishads: Green Dragon Zephyr Slash!" Li Yun successfully executed the five character chant and used the sword Qi in his hands to slash down towards the waterfall. With three "dong dong dong dong", the water in the waterfall scattered and everyone turned their heads to the side. After a violent explosion, the red door that was hidden in the waterfall was smashed into smithereens.

Li Yun had used his full strength in his Five Character Formula. At least one of the three times he could successfully execute this ultimate move. He had been cultivating for the past two days. Sure enough, refining was not in vain.

Lian Chengxue's body had been drenched by the water vapor just now. When he turned around again, he saw that Qingtian and Gu Liuma were completely clean without a single strand of wet clothes. He sighed in admiration in his heart: It really is the Tenth Order. Refining, however, was as vastly different as ever.

"Hehe!" Brother Li, not bad! " "I didn't expect that you would be able to use the Five Character Formula so skillfully in less than three days. You are indeed Feng Qingyang's chief disciple. "Son!"

"You are Feng Qingyang's disciple?" Gu Liuma was rather surprised to hear that. He sized Li Yun up before putting on a smile. "Indeed, new people come out of mountains and rivers. To be able to use the Five Character Formula at such a young age, it looks like our generation is getting old!" "Haha!"

"I'm sorry, Senior Gu must be joking!" Li Yun kept his Azure Dragon Sword quickly and said smugly, "What's the matter? I took a junior brother as well!"

"Junior apprentice-brother?" With a face full of doubt, Lian Chengxue, who was standing to the side, immediately lowered his head and laughed, "Let's talk about these things in the future. We should get down to business first!"

"That's right!" Li Yun stood up. With a leap, he walked through the door. "It's still best to be careful. If the Black Dragon were to set some traps, it would be troublesome!"

Just as he finished speaking, he suddenly felt something soft under his feet. He raised his foot and saw that it was the red pants and blue pants guarding the door. They had already been knocked unconscious by his sword qi, and his eyes were blurry as he laid on the ground, unable to move.

"Looks like there's no need to worry!" The blue sky came in and looked down at the guard lying on the ground. Then, he raised his head and pointed at the people who were still running in a steady stream.

"It's still the same as before!" Lian Chengxue had only taken a few steps when he turned his head and saw the portrait on the wall. He immediately covered his face and the three people behind him saw his strange expression and quickly asked, "What happened?"

"Shh!" Lian Chengxue quickly took out a towel from his bag and tied it to his face, "Look for yourselves. The entire city is filled with portraits of me and Xue'er. It seems like we are wanted!"

Gu Liuma looked at the portrait on the wall. It even had a crime of conspiracy on it. He caught two people giving him a thousand taels of silver. "We have to deal with Saint Black Dragon. We should try our best to avoid disturbing the common people."

He raised his head and looked at the sun in the sky. He asked in surprise, "Sky, could it be that this place is the same as the outside world? There's a sun in the sky?"

Qingtian looked at the sky and realized that it was almost noon. He then explained, "Senior Gu is the first person to come to this underground city. I better explain the situation here to you."

The Underground City was established a hundred years ago and was divided into the Sun City and the Moon City. The citizens of the city were all ordinary citizens and the Moon City was the military base of the Black Dragon Sovereign.

At that time, the Demon Lord was suppressed by Leng Qiuyu. His subordinate, the Lord of the Black Dragon, created an underground city to be his own king and disappeared from the face of the earth. However, a while ago, many young ladies had suddenly disappeared, all captured by the Black Dragon.

This Holy Master Black Dragon had a very good reputation in the Underground City and was even popular among the people. It was said that he had four generals under his command, all of whom were powerful and resourceful. One of them was a cat. Thus, if he wanted to kill the Black Dragon, he had to defeat its four generals.

After listening to Qingtian's explanation, Gu Liuma immediately understood. He stretched out his hand to stroke his beard, "So that's how it is. It seems like our mission this time will be very difficult!"

"That's right!" Lian Chengxue immediately followed up: "Previously, when I fought with that cat, Yao, its speed was extremely fast. It could kill without even being able to catch its shadow, making it a very difficult opponent!"

"Just a cat is already so amazing. There are three more people like that against him, not to mention that Saint Black Dragon!" Li Yun was a little worried, but for the sake of Xiang Xue'er, he had no choice but to bite the bullet and charge forward. "I can only hope that the Black Dragon's injuries are not completely healed after the previous battle. We still have a slight chance of winning."

"Yeah, that's the only way to go about it!" The blue sky estimated the time, "It is about time. We have entered the Moon City." When the night comes, it will be a very good time! "

"Hm!" That's right! " Gu Liuma nodded and headed towards the intersection of Sun Moon City. However, the cliff that spanned the middle of the city immediately blocked their path.

Lian Chengxue stood at the edge of the cliff. The cold wind from the opposite side sent chills down his spine: "The last time I went with Xue'er, I went there on a Taotie. What should I do now?"

Gu Liuma put his hands behind his back and smiled leisurely: "This is not difficult, leave it to me!"

The ground cracked open, and in the midst of the white smoke, a giant red bird appeared in front of the several people. Looking carefully, it seemed to look like a chicken, with bright red feathers all over its body, and in each of its eyes, there were two pupils, a multicolored tail dragging on the ground, and two feet on the ground as it arrogantly stood there.

"Roar!" It raised its head and screeched towards the sky. Then, it turned its head to look at the horse and asked, "Master, long time no see!"

"Heavy Ming Bird?" The blue sky looked at the big bird in surprise and praised, "I've only heard of it, and this is the first time I've seen it."

Li Yun scratched his head and looked at the huge bird. "Wow, what a big bird. What is a Heavy Ming bird?"

The horse lowered his head and laughed, explaining: "It is my summon! The Heavy Ming Bird was also one of the ancient mythical beasts. It was extremely powerful and could chase after fierce beasts. "Being able to get rid of disasters like wild beasts and such …"

Lian Chengxue stared at its sharp mouth and fearfully asked, "No way, could it be that this guy wants to eat people? It's just like Xue'er's Taotie! "
