When ye Shiyu and ye Lei wake up, they are sent back by Xiao Long. As for the ruined Tiangang City, Xiao Long asks Nie Tiangang to take some building materials and send someone to rebuild it.

Wuzhe's building speed was very fast. In a few days, the ruined Tiangang City recovered its former appearance.

The city Lord still let Nie Tiangang take the post, and Xiao Long was happy to be at leisure.

A month passed in a flash.

Xiaotian woke up as promised. Xiao Long also successfully learned how to use the doomsday meteor gun, found an open ocean and successfully used it once.

What makes Xiao Long helpless is that the real yuan in Xiao Long's body is consumed before the first blow is used up. It seems that Xiao Tian has to finish it in actual combat.

This move can be regarded as Xiao Long's most powerful killer mace. Its power has reached the level of third-order Emperor Wu, second only to complete demonization.

However, this move has a fatal weakness, that is, it takes too long to accumulate power. It is easy to be broken by the enemy when used in actual combat, and it will fall into a deep sleep after one use. Therefore, Xiao Long is still not sure that he can defeat Emperor Wu.

time lapse.

On this day, Xiao Long sent a split to the location of the rule crystal mine.

After a day and night's flight, Xiao Long's body arrived here and dived under the sea.

According to Nie Tiangang, the crystal mine blocks something. According to Xiao Long's experience, if you seal a demon head or a powerful monster, you will certainly use the magic sealing array or Lingbao to suppress it. Therefore, first of all, you can exclude living creatures.

In other words, there may be a space sealed here, or a cave, secret treasure and so on.

Xiao Long didn't know what was sealed. He had to go in and test it himself.

As for the serious consequences mentioned by Nie Tiangang, Xiao long ignored them directly. Donghe dared to send a group of congenital workers to dig in the past. Obviously, there would be no devastating disaster endangering fog island. Anyway, he can't get out of the fog island. Sooner or later, he will make the idea of the crystal mine. It's better to send someone to have a look first.

Xiao Long's separation came to the location of the mine cave. There was an array arranged by the East River. Now the East River is dead, and Xiao Long easily broke it.

Then Xiao Long entered the mine.

The mine is no different from two years ago. The only difference is that it is filled with sea water.

His divine sense carefully probed inside, trying to find a trace.

At this time, he suddenly detected that outside the mine cave, a giant whale sea beast swam over. The strength of the sea beast reached the second-order peak demon emperor.

The sea beast's divine sense also found Xiao Long, turned into a human form, and rushed into the mine in an instant.

After seeing Xiao Long, without saying a word, the sea beast sprayed a real Yuan water arrow at Xiao Long and smashed him.

In Tiangang City, Xiao Long's body startled and opened his eyes.

"I was found. Come again!"

Xiao Long gathered his body again and sent him to the sea of China.

The result was worse this time. Before he got close, he was killed by a bloody shark.

"Come again!" Xiao Long didn't believe in evil and sent him again.

However, the ending was the same. It was found as soon as it approached. It couldn't escape and was torn to pieces.

The giant whale, sea animal and bloody shark seemed to know that Xiao Long would come and stopped at the gate of the mine. Until Xiao Long tried more than ten times and failed, he was finally helpless to give up.

Xiao Long suddenly realized a problem... Why didn't those sea animals mine crystal?

Rule crystal is of great benefit to both humans and monsters.

It is reasonable to say that those sea animals live in the sea of China all year round. Even the East River has found the law crystal mine. Coupled with Xiao Long's more than a dozen times, they can't have found heresy.

This shows that the sea beasts must have known about the law crystal mine!

Since they didn't go mining, it shows a problem... They are willing to know that the mine is dangerous.

Xiao Long was suddenly surprised.

"Yes! Maybe the sea beast knows the secret of the mine cave. It's better to catch one and ask."

Xiao Long sent a separate body again.

Xiao Long's split body came to the seabed near the mine cave, grabbed a demon Saint level sea animal at random, then quickly ran away, took it back to fog island and refined it into a demon puppet.

"Say! What's the secret of the mine?" Xiao Long asked a mermaid in front of him.

"I don't know. The demon Emperor gave orders not to get near there." the mermaid said with godless eyes.

Xiao Long had no choice but to bring the mermaid into the world.

So, if you want to find out what the mine is, you must catch a demon emperor.

According to Xiao Long's exploration these days, the nearest to the mine is the giant whale demon emperor, the peak of the second-order demon emperor, and a bloody shark, the early stage of the second-order demon emperor.

In addition, there are two demon emperors who are relatively far away. They have also killed him. They are a black turtle and an eight legged squid, both of which are first-order demon emperors.

When, in addition to the four demon emperors who may know the secrets of the mine cave, Xiao Long also found tens of thousands of miles under the seabed, hiding an obscure and powerful breath. I'm afraid it exceeded the third-order demon emperor, which he was not qualified to touch.

In other words, his capture target can only be set on these four demon emperors.

"It's really troublesome. With my own strength and the black witch, I can't start at all." Xiao Long was very distressed.

Sea animals are no better than humans. Once a sea animal is attacked, if Xiao long can't kill it and retreat in time, it will certainly lead to the siege of other sea animals.

Once his body and the black witch fail and are surrounded by several sea monster emperors, he can only hide in the demon temple.

"Brother Xiao, I'm still thinking about the mine." Xiaobai went to Xiao Long and leaned against him.

"Well, I can't be trapped in fog island all my life. I have to find a way out. I think the mine cave is an opportunity." Xiao Long said.

Xiaobai smiled and said, "isn't brother Xiao a dragon? As a dragon, you can trade and cooperate with sea animals. You don't have to fight and kill."

"Come on, if the sea beast knows I'm a dragon, it's good not to chase me."

Xiao Long had no choice but to show his hands. He still remembered the last time he was surrounded by the sea of mastiff in the demon temple.

"Last time, they besieged you because brother Xiao was not strong enough, but now, as long as brother Xiao has enough negotiation capital, they don't dare to think about you!" Xiaobai said with a smile.

Xiao Long's eyes lit up when he heard about it.

Xiaobai's words seem to make some sense!

Negotiation capital, first of all, its own strength is hard enough, and second, it has enough helpers, strong enough to compete with the sea beast army chamber.
