Compared with the geometric Stone Formation area, the layout of the Ten Ribs is not only more difficult to crack, but also more dangerous.

Xi Mutong's description of this place was more attentive than before, for fear that the generals would not understand something, so he used a lot of methods to match the front and back in order to be as vivid as possible.

Her hope is that they can feel immersed in the scene at this time, and when the real fight begins, they will not be unfamiliar with the environment.

The ten ribs are the channels for energy transmission, and all the organs in the Void Cold Valley must rely on the energy they send to maintain normal operation, and the divine soldiers must not act without orders. The generals knew what was at stake, and they would take strict control of their men when the time came.

Of the 60,000 soldiers, another 10,000 will be left to guard the rib road, and nothing can be done until a new order is received. How should the remaining 50,000 be dispatched?

Mars, resting on the Wind Boundary, wandered again, until it reached the Ten Ribs, between two buildings that resembled two lungs.

Xi Mutong said: "If you think that these are two houses that can be lived, you are wrong. They were actually two huge gas refining furnaces, made of strange soil containing the blood of Han Xuzi in the Void Cold Valley. At will, the outer walls of the gas refining furnace are intact and the doors and windows are complete, as if it is indeed used for residential purposes, but in fact, it is only a camouflage. The furnace is filled with it, but the divine energy that has been cultivated in the evil god dantian for thousands of years. ”

"What? Nangong ...... to him Not to mention turning his master's dantian into a valley, but also pouring divine energy into the giant furnace? What exactly does he want to do? ”

Xi Mutong explained: "Taoism has a saying about alchemy, and alchemy requires a Dan furnace. Nangong Xiang didn't need alchemy, but he needed to reserve a large number of energy pills, so those two giant furnaces became his gas refining furnaces. Han Xuzi's dantian qi has been precipitated for thousands of years, and it has become an extremely stable energy, which can be burned into ice and fire. Ice and fire have no heat, and as a medium, two different types of energy can be transitioned, and the mass, direction, and even structural shape of the particles in it are adjusted exactly the same. When they are mixed together, not only will they not explode again, but they will also be incredibly stable. With this kind of energy ball, Nangong Xiang will be able to fill it with poison gas and turn it into an energy poison ball. ”

Mo Jing asked, "Xi Muxian, when you talk about this, can I understand that energy ball as a stable energy ball that will never explode again after being tempered by the ice and fire of Han Xuzi's dantian in the gas refining furnace?" Since it won't blow up, what's the use of Nangong Xiang asking for something so stable? ”

Xi Mutong said: "General, don't worry, listen to me." If it was to be used for detonation, he would have colluded with foreign forces to create an electric fire thunderball bomb on the border of Yunnan. The skill of that kind of thunder bomb is so mature, and it is superfluous to find a replacement. Nangong Xiang is ambitious, whether it is here or back to his Demon Domain space, he is planning to do great things, and he will not waste resources at will. Therefore, the purpose of using the gas refining furnace to create energy bombs is to release poison gas, not to cause an explosion. ”

"God, although they are all used to do evil, they have different functions!" The generals nodded their heads in understanding, shook their heads and sighed, and the Hokage Bronze Mirror was so lively for a while.

The brainwave connection with the bronze mirror may be interrupted at any time, Xi Mutong was worried, and hurriedly pulled them back, "Everyone, because the gas refining furnace is important to Nangong Xiang, it is also of great significance to us to destroy the Void Cold Valley. The connection between the ten ribs and the two giant furnaces is through a gas pipe buried in the ground, so there is no sign on the stove surface. What the divine soldiers needed to do was to enter the gas refining furnace. ”

Hao Lie came again urgently, grabbed the conversation and said, "Is it to extinguish the ice and fire by drilling into the gas refining furnace?" ”
