"What's in there, but it can't be opened. Ah, wait, the key? Lin Ao was stunned and remembered his key.

"The key, I have it!" As soon as Lin Ao stretched out his hand, he could naturally open the universal fire key of all fire type treasure chests, fire gates, and fire locks.

Meng Huoshi was surprised: "Brother Shi, this key of yours." ”

"A fire-based master key that I get occasionally."

"Fire Master Key, Brother Stone, if that's the case, let's ......" Meng Huoshi suddenly became excited, and was about to say something.

"But can it really be opened? This ......" Meng Huoshi was puzzled again, frowning in doubt.

"Little Sister Huoshi, what's wrong?" Lin Ao was strange, Meng Huoshi looked like he wanted to speak and stopped.

"It's nothing, it's just a surprise at this fire-based master key."

"Is this really okay with the key I got occasionally?"

"No, nothing."

Meng Huoshi looked like he wanted to speak and stopped, Lin Ao didn't want to ask, and looked at the key in his hand again and the locked Fire Dragon Tianfu box.

"Can it be opened?"

"The Ancient Key—"

"Dragon Dragon Dragon Key!" Lin Ao snorted softly, and the key in his hand headed towards the Fire Dragon Tianfu Box.

The dragon head key has a piece of fire dragon pattern and light, which is somewhat similar to the fire dragon pattern on the treasure box. In the midst of the roaring light and the fire dragon, it was inserted into the lost fire dragon Tianfu box with a bang, and it felt heavy and was about to be opened.

"Ah, can you really open it?" Lin Ao twisted excitedly, the key in his hand sank and could not be opened but was drawn out, Ding Dong: The knight is a strong stone, you use the dragon head key to open the treasure box in your hand. I'm sorry, although the box is a box of fire dragon Tianfu with a fire dragon pattern, it is not a box of fire elements, and your dragon head key is invalid, and you can't open the fire dragon Tianfu box in your hand.

Ding Dong: To open the Fire Dragon Mansion, look for the key to the Fire Dragon Mansion, or any other master key that can open the ancient lock.

"I go, I can't open it."

"It still looks like it can be opened, I'll go, I'm excited in vain."

Lin Ao shook his head, and put the lost Fire Dragon Tianfu Box and the Fire Dragon Dragon Head Key into his backpack. Looking at the secret room and platform again, the secret room was empty and there were no more items, and the platform was destroyed and there were no more items, Lin Ao shook his head: "It's a pity, the last piece of the mission is the Fire Melting Heavenly Divine Sword." ”

"Third Master, wait, I will definitely retrieve the Fire Melting Heaven Divine Sword of our Fire Raven Ancient Temple."

"As for ...... now"

Lin Ao looked at the empty secret room again and the underground volcano outside: "Hurry up, I finally led the third master away, and if he saw the loophole and returned quickly, we couldn't escape." ”

Took Meng Huoshi out of the secret room and prepared to leave, and at this time, the underground volcano exploded and burned, the red flames and volcanoes continued to explode and erupt, and they had been suppressed and cultivated by the three masters for more than a thousand years, and after the control of Lin Ao's volcanic fire dragon fire, as well as the strengthening of the Vulcan Earth Fire Explosion Pill and the Chixiao Burning Fire Flag.

Boom Boom Boom ......

Thousands of meters of underground eruptions of large volcanoes erupted uncontrollably.

Ding Dong: The knight's strong stone, the underground volcano you are in, the underground volcano cultivated by the third master of the Fire God Land, the underground volcano that has been suppressed and absorbed by him for more than a thousand years or even longer, plus the control of the fire dragon volcano dragon you just now.

Dingdong: The knight's strong stone, the large underground volcano you are in has been stimulated, and it is a little bit short of an element to erupt, and it wants not to erupt but cannot control the want to erupt.

Knight strong stone, your current situation, either leave regardless of it, or use your volcanic fire dragon fire to control the surrounding underground volcanoes again, let them calm down, you can also control the surrounding underground volcanoes, let them erupt wantonly.

Ding Dong: Once it erupts, it will flood the cultivation place of the third master where you are, and even rush into the sky to break through the stone cave and flood the thousands of square meters of territory above.

Dingtone: How do you deal with it?

"Ah, what else can you do?" The system suddenly sent a prompt, which exceeded Lin Ao's expectations.

Also, this is a large underground volcano that has been suppressed for more than a thousand years and controlled by his volcanic fire dragon fire.

How to deal with it, leave quietly or do something? Lin Ao hesitated, no, he destroyed the third master who slaughtered the Fire Crow Ancient Temple, and the Fire God Palace, supported the East Hall Lord of the Heavenly Sword Villa to defeat him and his sister and seize the mastermind behind their Heavenly Sword Villa. Moreover, maybe the third master saw some flaws, and on the way back, he met them who were about to leave.

If he is discovered by the third master, he will die.

"This?"

Lin Ao frowned, and also nodded: "Fire God Palace, damn it!" ”

was about to leave quietly, but at this time he shouted: "The power of strange fire-"

"Volcanic Fire Dragon Fire!"

The coaxing volcanic fire dragon fire flew, and the pattern of the volcano and the volcanic fire dragon in the sky waved again towards the thousands of meters underground volcano that was buzzing and exploding around and wanted to erupt: "Come on-"

"A great underground volcano!"

The large underground volcano of thousands of meters boiled and exploded, surrounding Lin Ao, and it was also controlled by Lin Ao's strange fire and outstretched right hand.

Ding Dong: The knight's strong stone, you once again urged the volcanic fire dragon fire of the power of the strange fire, and controlled the large underground volcano thousands of meters around. Thousands of meters of underground volcano explosion boiling, can be suppressed by your volcanic fire dragon fire, can also erupt under the control of the volcanic fire dragon fire.

Dington: Knight Strong Stone, How Do You Choose?

Again, prompts and inquiries came.

"Good!"

"Come on—"

"The Great Underground Volcano—"

"Eruption!"

"Volcano Fire Dragon Destruction Technique!"

Lin Ao made a quick decision, waved his hand towards the underground volcano, and also used his strongest skill.

A large underground volcano of several kilometers erupted and swept towards Lin Ao and Meng Huoshi. However, this is a volcanic eruption controlled by Lin Ao's volcanic fire dragon fire, forming a volcanic fire dragon aura that surrounds him and Meng Huoshi: the knight's strong stone, this is the volcanic eruption controlled by the volcanic fire dragon fire of your alien fire power, you and your teammates Meng Huoshi are surrounded and protected, and the volcano that is immune to the eruption will not be harmed.

The two of them were immune to attack, and were swept up by the eruption of the volcano, breaking through layers of rock and earth towards the sky. One second, five seconds, ten seconds, twenty seconds...... In just twenty seconds, there was a boom, and the erupting volcano burst through the earth and into the sky.

Ten meters.

Twenty meters.

One hundred meters.

Two hundred meters.

Five hundred meters.

Eight hundred meters.

……

The volcano that rose into the sky was 800 meters into the sky.

Ding Dong: The knight's strong stone, you let the third master's underground volcano erupt, the volcanic eruption that has been suppressed for more than a thousand years or even thousands of years, plus the enhanced power of your Volcanic Fire Dragon Fire, Vulcan Earth Fire Eruption Pill and Chixiao Burning Fire Flag, breaking through the earth and rushing up to the sky of more than eight hundred meters.
