At this moment, two magicians of the sub-dragon clan slacked lightning and the other set fire, which was just enough to cause output.

With Long Aotian's restraining power, this guy seemed to have found Optimus Prime's weakness, which can also cause some damage. Slowly fighting can indeed kill this boss.

Thinking of this, Luo Yu showed a sneer on his lips, and he saw a little bit of his fingertips, and the Yitian Sword and the Qingyan Sword rose up!

"Swoosh!"

The next moment, two swords flew out, and in just a blink of an eye, the two magicians of the sub-dragon clan were cut off their heads.

At the same time, a dark shadow flashed at the gate, and the originally open door closed with a bang!

The entire reactor room became a secret room!

"What!"

Everyone was shocked and shocked. Long Aotian suddenly reacted, and ignored the boss and shouted: "Open the door and rush out!"

Several sub-dragon tribe trialists grabbed the heavy mechanical door handle and then pulled it hard, but the door just trembled slightly and was not pulled open!

"Young Master! The door was blocked!"

This scene made everyone panic. Long Aotian avoided a laser and shouted: "Wan'er, you block it for a while, I'll open the door!"

"good!"

Murong Wan shouted softly: "Surround the mountains and rivers!"

A giant sword slashed on the boss's forehead. Although it did not cause any damage, it attracted the robot's attention.

"Defend the reactor!"

"Tututututututu..."

A large number of laser bombs were fired in the robot's palm, and Murong Wan hurriedly dodged and launched the game-fighting tactic.

On the other side, Long Aotian grabbed the handle suddenly, then pulled the other side with both hands. He was very powerful and the door was opened in a gap, but a huge force immediately came from the handle outside the door and actually pushed it back.

"Who dares to plot against me!"

Long Aotian was furious, and his arms veins burst out and opened the door with force, but the power of the person outside the door seemed to be extremely amazing, and he couldn't even open the door!

"Young Master, let's help you!"

Four or five trialists of the sub-dragon tribe grabbed the handle and pulled it violently. Luo Yu outside the door felt a huge force and almost couldn't resist it. The Valkyrie beside him immediately helped and rushed back again!

Luo Yu’s own power is actually not as strong as Long Aotian, but as a mage, he has a buff!

The whole body buff, coupled with the Valkyrie's super strength and Xiaokong, who also had a full body buff, the three of them forced the strength of more than a dozen people on the other side back!

Of course, the main reason is Valkyrie. She is very strong and can definitely not withstand it with Luo Yu and Xiao Kong alone.

Aside Long Aotian, a female sub-dragon tribe trialer gritted her teeth and said, "Young master, there are at least hundreds of people outside the door holding the gate, either the blood clan or the Kui Shui clan who had a feud with us! Why not try to forcefully break the gate!"

Long Aotian frowned slightly. He also knew that the hard push might not be able to open it. The opponent killed two mages first and then locked the door, which obviously would trap them to death.

The reason why this door was open before was because the reactor would emit very high heat, which was open to facilitate the heat dissipation. If the door continued to close, the heat in the room would continue to accumulate, bringing the temperature to a terrifying level!

In just a moment, it has increased from the original 25° to 50°!

Long Aotian said in a deep voice: "You all get out of here!"

Everyone immediately dispersed, and saw a phantom of the real dragon circling around him. The spear emitted a wave of dragon roars, and the next moment it swept out!

"Crazy!"

The tough spear head hit the door, and the entire house shook slightly under the collision, and the shock wave rolled up a layer of heat wave that made people retreat involuntarily.

Everyone hurriedly looked at the door, and the door was broken!

Long Aotian's shot actually knocked the door a white dot!

"this……"

Everyone looked at Long Aotian. The strength of this gate was simply incredible and could not be blasted open with human power.

The temperature was still rising rapidly, and it had risen a lot in a short period of time. Long Aotian glanced at the boss who was still half blood, and his eyes were even more cold.

"The dragon breaks the nine heavens!"

"Boom!"

A real dragon hit the gate, and the whole room was violent again. The attack was even more fierce than before, but it seemed a little insignificant before such a strong gate.

Long Aotian was bombing continuously in anger, and the blood in his body was boiling, and the dragon breath was surging around him. All the attacks actually hit the white dot. With the continuous bombardment, the white dot began to expand, and cracks appeared around it.

"Long Xiang shines in the world!"

It was the real dragon hit again, and the sub-dragon tribes around him showed expectation in their eyes. If this continues, it seems that it may break the door, but Long Aotian's heart is full of despair.

At this moment, the temperature exceeded 100 degrees, and even he had little energy left. Judging from the current progress, he would be devastated by heat before breaking the door!

"Bang!"

With an explosion, accompanied by the woman's scream, Long Aotian quickly turned his head, but saw Murong Wan being hit by a laser bomb, falling to the ground, with blood spilling from her mouth.

But there was no room for buffering at all. The next laser bomb came over, and she hurriedly provoked and dodged, barely dodged.

If this continues, I am afraid that the boss will be killed first!

"Who wants to harm Wan'er and me, who is it!"

Long Aotian was furious and violently bombarded the gate with a spear in his hand, but the gate stood firm and there was also a quiet outside the gate.

After a while, the temperature soared to 200°. The surrounding sub-dragon tribe could no longer bear it. Long Aotian was still bombarding the gate. When everyone was almost desperate, a sudden sound of metal shattering sounded.

It was not that the door was broken, but two pieces of muzzles suddenly rushed out of a wall, shattering the surrounding walls. Two ice cubes with mysterious runes were carved from the muzzle. The next moment, a large amount of air conditioning surged out!

"Brother Tian! There is a hole here!"

Murong Wan exclaimed in surprise, and Long Aotian immediately rushed to Murong Wan and picked her up. After glanced at the already weak tribe members, he gritted his teeth and rushed into the hole.

Before rushing into the cave, Murong Wan's long sword swept out and rolled up a rune ice brick on the ground, and the two disappeared.

The next moment, the temperature inside the room dropped rapidly, from the original speed of light of 200°C to minus 250°C. Luo Yu, who was holding the handle outside the door, felt the extreme cold on the handle and hurriedly let go.

I saw the entire door formed ice at a speed visible to the naked eye!

"Is this...Is it... that the temperature is too high that triggers the automatic cooling device?"

Luo Yu was not sure what was happening inside at this moment, so he didn't dare to enter rashly.
Chapter completed!
