Chapter 3409

"Oh my God, it's really a passage to the upper world!"

Looking at the passage with divine power, the big evil dragon knew what it was. His eyes widened and he stopped lying lazily and stood up.

The next moment, its huge dragon body suddenly emerged from the cliff hole and rushed towards the upper boundary channel as fast as a hungry wolf had seen meat.

Although this guy is old, he runs very vigorously and is not senile at all. He runs extremely fast and his purpose is very obvious, pointing directly at the entrance to the upper realm!

In just a blink of an eye, it had already reached its target and was about to enter the upper realm passage...

However, someone's hand speed was faster than it, and the upper boundary channel was dragged instantly, and the entire upper boundary channel disappeared out of thin air.

"Well……"

The big evil dragon rushed over, only to find that the passage to the upper world was missing, and he felt lonely.

"You actually closed the upper bound passage?"

"How dare you close the upper body passage?"

"Hurry up and release the upper realm passage, or you will die!"

The big evil dragon was so angry that he shouted angrily and was about to go on a rampage.

It has been waiting for countless thousands of years, and finally when a passage to the upper realm is in front of it, it must ascend to the upper realm as soon as possible.

But Lu Chen actually took away the upper realm passage at the critical moment. Is this still an exchange of benefits?

Is this just for fun?

It would be a ghost if it didn't attack the heart with anger!

"Old evil dragon, what are you in a hurry for? Just calm down first and listen to what I have to say."

"I showed you the upper realm passage. It was for you to see. It was to prove to you that I really have the ability to reach the upper realm and I didn't lie to you."

"But it's not for you to board now. You haven't explained some things yet, so our exchange of benefits hasn't started yet."

"When you finish everything, you can go to the world as much as you want, and I won't bother to care about you!"

Lu Chen smiled.

"As soon as I leave, the Evil Dragon Valley will be yours. What else do I have to explain?"

The big evil dragon asked with lingering anger.

"Didn't you say that before you left, you would leave a piece of dragon scale to calm the evil dragon outside?"

Lu Chen said.

"oh!"

"I was so happy that I forgot about this. Damn it."

"This is bullshit. I'll get it for you right away."

The big evil dragon slapped its head and immediately stretched out its claws to the bottom of the dragon's belly and pulled out a piece of dragon scales, but it was so painful that the dragon shed tears, "Oh, what a fool, it's really hard to pull this thing out" It’s terrible, it hurts me to death!”

The dragon scale was not that big, only about the size of the face, and much smaller than the dragon scale on the back of the big evil dragon, but the roots of the dragon scale were filled with bright red dragon blood, and there was a steady stream of terrifying dragon breath.

However, when Lu Chen looked at the big evil dragon who was in pain as if it were being cut from an egg, he was a little puzzled: "Isn't it right? If you just pull the dragon scales, it can hurt like a bird?"

"You know nothing!"

The big evil dragon was resisting the intense pain and couldn't say much. He just replied casually in his anger.

"Boss, you don't know something. The evil dragon's scales are not ordinary dragon scales!"

At this time, the green-scaled dragon came closer carefully and whispered to Lu Chen, "It is a dragon scale pulled from its belly. Those are its reverse scales and the essence of the dragon. It hurts to pull this thing off!"

"I see!"

Lu Chen suddenly realized it and felt relieved at the same time.

The dragon's reverse scale contains a lot of dragon's breath, and the power of shock is also strong. As long as there is one here, it is enough to suppress the evil dragons outside.

"As long as my reverse scale is here, just like my true body is here, the losers outside won't dare to come in."

After the big evil dragon relieved the pain, he threw the piece of reverse scale back and inserted it on the cliff wall to the left of the entrance of Daya Cave. Then he said to Lu Chen, "Now the Evil Dragon Valley is yours. Quickly take out the passage to the upper realm. I want to ascend to the upper realm immediately. I have been waiting for countless years and I don’t want to wait any longer.”

"There is one last thing, the Mandala Immortal Crystal!"

However, Lu Chen did not take out the upper realm passage. Instead, he pointed to the countless Mandauo Immortal Crystals on the cliff and said, "Help me take down all those things. Even if our exchange is completed, you can also board the realm to transform into the real dragon." And left."

"You still have to ask me to take action, don't you know how to get it yourself?"

The big evil dragon said angrily.

"Old evil dragon, stop joking, I can't take off those Mandala Immortal Crystals!"

Lu Chen smiled and said, "No one can take it down except you, unless my realm is Taiyi Immortal King!"

Although those Mandauo Immortal Crystals look easy to obtain, there is actually a special force spreading on the cliff, covering all the Mandauo Immortal Crystals.

Lu Chen sensed that the power was terrifying, and he couldn't break it, not even An Yu.

The big evil dragon guarding the Mantuo Immortal Crystal has the terrifying strength of the twelfth level peak, and should be able to break the power on the cliff.

"Heir of Kowloon, you are very careful. You have seen this, so I will finish the work."

The big evil dragon smiled awkwardly, then turned around and led Lu Chen back until he reached the bottom of the cliff cave.

In fact, it didn't want to help Lu Chen get the Mandauo Immortal Crystal, which would waste a lot of time.

But Lu Chen was a human being, so he couldn't fool him, so he had to take action himself.

Flying is prohibited in the Miao Bo Secret Realm, as is the Evil Dragon Island. You must climb to get the Mandala Crystal on the cliff.

But there is that powerful force shrouding the cliff, and it is impossible to climb up if it cannot be broken. Only the great evil dragon at the peak of the twelfth level can do this job.

In fact, the big evil dragon couldn't break the power on the cliff. Instead, he climbed up against the power, then pulled the mando fairy crystal off the cliff wall, and then threw it to Lu Chen on the ground.

On the cliff, there are countless Mandauo Immortal Crystals growing. The big evil dragon does not have the ability to remove them on a large scale, so it can only remove them one by one.

Although the big evil dragon can pick the coins very quickly, picking them one by one is still very time-consuming.

What's terrible is that there are so many Mandala Immortal Crystals on the entire cliff, at least millions of them, and Lu Chen wants to take them all!

In order to ascend to the world, the evil dragon had no choice but to fight.

As a result, the big evil dragon spent three days and three nights before finishing the last Mandala crystal, and almost broke his keel from exhaustion.

The force on the cliff is not weak, and it always puts pressure on the big evil dragon. If the big evil dragon hadn't been strong enough, it might have been unable to hold on long ago.

"Ni Ma Ma, I insist on millions of Mandala Immortal Crystals. You insist on taking them all. I am really exhausted."

The big evil dragon returned to the ground, panting and complaining.

"Thank you for your hard work. The upper realm passage will be arranged immediately!"

Lu Chen chuckled, and was about to drag the Chaos Pearl out of the upper realm passage, but was interrupted by a shaking of the ground.

Immediately afterwards, he felt that some kind of power was disappearing, and he quickly looked up...

Sure enough, the entire cliff was shaking, and the power that enveloped the cliff was gone...

Moreover, the barrier at the entrance of the cliff cave was also gone. He saw that there was a light door deep inside the cliff cave...
