Outside the fire source cave, Yinglong and others were waiting patiently.

Before, they had heard Su Yang's voice and naturally felt relieved.

After waiting for a while, seeing that the flames at the entrance of the cave suddenly weakened, several people drilled into the cave one after another.

There was a high temperature along the way, which made them almost unable to breathe.

Even if there is oxygen cylinder, it feels extremely uncomfortable.

"My shopkeeper, my colleagues, I suggest not to go in. After all, we have an oxygen cylinder, and if we encounter an open flame, it will explode. Also, this oxygen cylinder cannot withstand such a high temperature, which is also very dangerous. Please think twice."

The Panlong King, who had not made any sound, suddenly said.

When he said this, everyone's faces were frozen and they couldn't help but stop.

Oxygen cylinders cannot encounter open flames, otherwise they will easily explode.

What's more, the cave here is narrow, and if it explodes, everyone will die.

Only Li Dongna walked forward alone.

However, the more you go inside, the temperature gets higher and higher.

"Donna, don't walk inside. It's too dangerous."

Yinglong said.

Because there is no fire, it is dark inside, even if they cannot shine with flashlights, they don’t know how deep the fire source hole is.

"Su Yang, where are you, where are you? Let me reply."

Li Dongna shouted loudly.

But through the protective helmet, the sound was much isolated and not loud at all, so it could not be transmitted far.

However, there was only a little echo inside, and there was no other sound at all.

But the temperature is getting higher and higher.

"Big shopkeeper, should we still walk inside?"

Yunlong King asked.

"Let's do it, you all go out, I'll go in and take a look. I believe that Su Yang must be alive."

Yinglong pondered for a while and said.

"Well, dad, this won't work. Otherwise, I'll go in alone."

Li Dongna said.

"Dona, it's the most suitable for me to go. After all, I know a little formation. Besides, with my true energy barrier and this layer of protective clothing, there is no problem in going in."

Yinglong explained.

He also ordered the Yunlong King Panlong King and the others: "Now, I order you to take Master Li out and wait outside the cave entrance for me to bring Su Yang out."

"yes."

The Panlong King immediately replied and asked King Yunlong to pull Li Dongna back.

"Don't pull me, let me go in with my dad."

Li Dongna insisted on not going out with them.

"You guys pull her out."

Yinglong said, without looking back, he walked into the cave.

"No, I'm going to go in together."

Li Dongna said stubbornly.

But he could not withstand the power of the two dragon kings and was immediately led toward the entrance of the cave.

At this moment, I suddenly heard a loud bang outside the cave, as if something exploded, and the shock wave emitted quickly scattered in the air and caused a resonance.

Buzz...

The sound waves are endless, making the mind swell and the qi and blood are restless, as if the whole world is about to collapse.

"No, there is something wrong with the mountain protection formation."

The first shot of the Panlong King should be guessing whether there was a problem with the mountain protection formation that protected the Longyin Base.

Because this buzzing lasted for a long time, it was not like an explosion at all.

At this time, Ying Long, who had just entered, walked out quickly.

The four of them hurriedly walked out of the fire source cave, but saw some abnormal airflow fluctuations above Long Yin in front. The colorful Banlan was extremely magnificent.

Yinglong took off his helmet, stood on a small hill, observed it carefully, and closed his eyes and felt it intently, and suddenly looked depressed.

"How about it, the big shopkeeper."

King Yunlong asked in confusion.

"As King Panlong said, there was a problem with the mountain protection array, and the fire energy has been cut off, making the array an incomplete array, and its power has been reduced by one fifth."

Yinglong sighed.

"Is it because the flames in the fire source cave are extinguished?"

The Panlong King stared at the deadly fire cave and said in a deep voice.

“Not ruled out.”

Yinglong glanced at the Panlong King and nodded.

"Well, I feel the temperature around me has dropped a lot. Is this place already stopped?"

King Yunlong also said curiously.

He took off all his protective suits, walked around, nodded, and said, "The temperature has dropped completely, which is similar to the normal temperature. I guess the energy in this fire source cave has been lost."

The Panlong King raised his eyebrows, "Yunlong King, you can't say anything nonsense. If the formation of the mountain protection formation is gone, wouldn't it fall into the sky?"

Yinglong also took off his protective clothes and felt them carefully.

He didn't say a word, but his two sword eyebrows seemed to be about to twist together.

At this moment, suddenly, three old men flew out of thin air in the front directions, one of which was the Evil Emperor who appeared last time.

The Evil Emperor came first, and the other two shouted: "Yinglong, Yunlong, Panlong, what are you doing? Why did you close this line? Do you know how dangerous it is to do this?"

Another man came and said unhappily: "What are you doing? Are you going to collapse the Longyin Base? He actually closed the line privately."

This old man was dressed in a blue dress, with disheveled hair and thinner bones than firewood. This man could actually walk against the wind.

Another big sword carrying a sword that was about the same length as others, flew over like a stream of light, standing on the hill at the highest point, his eyes were as lightning as lightning, staring at this side coldly, and asked, "Who is looking for death, and dares to close the ground?"

As soon as this was said, the surrounding temperature dropped a lot.

"Old Xie, Old Feng, Old Jian, you are here too. I'll pay homage to the three old seniors."

Yinglong Yunlong Panlong and the three dragon kings bowed to these three old men.

Li Dongna also bowed to these three old men, and was a little puzzled.

He had seen the Evil Emperor, but he had never seen this old man Feng and old Jian.

But it can be seen that these three old men have a transcendent status and are also figures from the same era.

"Well, you three dragons, explain to me what's going on. Who is so bold that he closed the mountain protection array. Do you want to cause big trouble?"

Feng Lao said coldly.

"You three seniors, this is the case. Recently, a young man came to our base, with super strength. He just entered the fire source cave alone, which made the flames here disappear. I wonder if it was his closed position?"

Yinglong said truthfully.

In this situation, he dared not lie.

These three old men are the big guys of the previous generation and can be called living fossils.

In normal times, it is a very amazing thing to be able to have someone.

There were three people coming out at this moment, which naturally shocked everyone.
