Based on Xi Mutong's description alone, it is difficult for Haolie to have an idea of how dangerous the furnace of the gas refining furnace is. But as soon as he drilled through the security barrier set up by the Phantom Sword Array, and then entered the furnace door, he really realized that the theory of ice and fire was completely true.

As soon as he touched the cold of the flames, the will to open his eyes disappeared, his consciousness seemed to be sucked away in an instant, and his body became light. If this state is allowed to continue, within five seconds, he will die in the fire, but as a strong soldier, the subconscious self-discipline plays a role at this time, reminding him that he must fight against ice and fire, otherwise not only him, but also the few divine soldiers waiting by the door will be killed by the laughter of ice and fire because he is too late to close his ears.

At the critical moment, he was finally able to react in time, and his palm freed up the Hokage's aura, forming a Hokage protective shield to protect his whole body, and he struggled to open his eyes. At the same time as he opened his eyes, a strange laugh that seemed to be far away and near, and it was difficult to distinguish between true and false, unexpectedly, he must have seen that the intruder was not dead, and the ice and fire who was cast used the second killing move.

"Quick! Close the ear acupoints!" The moment the laughter started, he shouted angrily, and the divine soldiers followed him to life and death, and had already formed a conditioned reflex to his voice, and before the words fell, they had already pointed their fingertips behind their ears to resolve the first danger.

The ice and fire in the gas refining furnace were raging, and the energy balls were floating everywhere, this time, Xi Mutong not only faced the problem of being difficult to enter, but even the dragon tooth mirror mirror soul no longer played a role, so the large army waiting outside the gas refining furnace completely cut off contact with the people inside the furnace.

The first level turned danger into relief, even if the ice and fire were cold, Haolie was still shocked into a cold sweat. An hour ticked to begin, and a broken soldier stood on a platform jutting out of the furnace wall, holding an hourglass aloft.

Inside the furnace of the gas refining furnace, Xi Mutong did not elaborate, so Hao Lie carefully looked at it first to determine the layout of the battlefield.

As soon as he entered the furnace door, each foot stepped on a silver air mass that fluttered like ghostly fire. The air mass did not come to welcome him, but to support him, moving towards the middle of the hearth to throw him into the hearth.

What burned in the furnace eye was the ice and fire ignited by the gas of Han Xuzi's dantian as fuel. The color of the flame is really a mixture of green and white, if it is not in the shape of a flame, I dare not say that the clusters are bursting up with fire. The highest flames were only level with the platform that had been erected along the walls of the hearth, but above the flames, and even the entire hearth, were the horrible silvery gas masses.

Under the Fengjie River, the poisonous gas bag can burst at the touch of a button, but the air mass here is different from the air bag, not only can it not be broken, but it can be twisted into various shapes when pressed by hand.

Hao Lie thought secretly: "After the energy is directly extracted from the wind, thunder and the human body, it is still unstable, and it has to be fed into the gas refining furnace through the underground rib channel, and after being neutralized by ice and fire, a stable energy poison ball is formed." Nangong Xiang regularly came to collect it, and then passed it to the Condensing Qi Tianyun District, how did he pass it on?

I didn't ask Xi Muxian about this question at the time, but when I thought about it, I could only explore it myself to see if I could find the answer.

At first glance, the structure of the hearth is simple, only the eyes of the furnace that burn with ice and fire, and the platform that can be walked on by the wall of the furnace, and then those energy balls that obscure the view from time to time.

What he was most anxious to find was the location of the control gate, and when he looked around, he found that on a platform facing the furnace door, there was a circular protrusion, and the shadow of the red, white and black handle could be faintly seen, which must be what he was looking for, and the reason why it was so blurry was because the circular bulge was separated by an air barrier, and it would only be mixed with the surrounding platform without careful observation. It seems that Nangong Xiang is so wary that he has not forgotten to use the trick in the furnace.

The protrusion came from a wooden box-like device, and the divine eye penetrated it, and Hao Lie could see that it was full of gear chain mechanisms, which was probably the basis for the linkage between the control gate and the fan blades overhead.
