Chapter 2159: Tianmo

  Los Empire went all the way to the north, the weather was getting colder and colder, the ice and snow had not yet melted, and the mountains and rivers were white.
  A mountain and river traverses the northern border, blocking the cold from the polar ice sheet, and also leaving an environment in which humans can survive.
  The mountain range that stretches for hundreds of miles is called the Gus Mountain Range. It runs through the east and west, like a moat, guarding the northern border of the Los Empire.
  After crossing the Gus Mountains, there is an ice sheet that does not melt all the year round. The thickness of the ice can reach thousands of meters. It is said that if you go north, you will enter the land of eternal night. No one knows what is buried inside.
  This polar ice field is a forbidden area for all living things. The bone-chilling cold will quickly take away your body temperature. Even if you are motionless, your body energy will be quickly consumed.
  Even the snow rabbits and snow foxes that are common in the north are hard to find on the ice field.
  Gus Mountains blocked the cold wind and isolated the existence of life.
  However, at the moment on the side of the Gus Mountains near the ice field, there is a team of engineers with thousands of people busy under a cliff.
  The cliff on the side of the ice sheet is covered with a thick layer of ice. Under the cold wind, it is smooth as a mirror. The cliff is hundreds of meters high and is a pure natural city wall.
   But after all, it is a mountain range, and there are always large and small gaps between them.
The elites of the major legions of the   Los Empire are gathering to the north, while the engineering regiment of the Northern Legion was transferred to build fortifications under the Gus Mountains three days ago.
  To prevent the undead army from going south, the Gus Mountains is the only option.
  The polar ice sheet is vast and the weather is extreme. It is unrealistic to take the initiative to look for the undead army on the vast ice sheet.
  After passing the Gus Mountains, all the way south, there is no danger that can stop the undead army.
   With the help of the natural fortifications of the Gus Mountains, the entire mountain range was turned into a great wall of hundreds of miles, and the undead army who tried to go south was stopped and decisively battled outside the empire.
  This is the policy set by the commanders of the coalition forces Alex and Marshal Dominic. No one of the soldiers of the Ross Empire will question the decision of these two adults.
"Be quicker! Today we will fill in these pits and spread the area with glutinous rice, and we will have barbecue for you tonight! The brother on the watch just caught a few snow deer!" A tall knight looked at Said loudly to the engineers who were working.
"okay!"
   Hearing that there was meat to eat at night, the engineers and soldiers carrying ice cubes suddenly brightened their eyes, and their work was much easier.
  This is a gap of ten meters wide. From this gap is a covered by ice. For ordinary people, it is still an insurmountable sky.
  But according to the reports of the spies who entered the ice field, those skeletons can easily climb up as long as the is slightly inclined, let alone such a gentle slope.
  So they have to use ice mined from the ice sheet to plug this gap and connect it with the vertical cliffs on both sides to form a complete city wall.
  This is also what the tens of thousands of engineers are doing now under the Gus Mountains.
  Of course, just relying on these engineers and soldiers, filling in such a gap, it is impossible to complete without ten days and a half months.
  Fortunately, a dozen magicians were assigned to their team. The wind magicians were responsible for cutting the ice cubes, and the water magicians poured water into the gaps in the ice cubes. After natural solidification, it became a solid ice wall.
  The ice magician is even more like a fish in such a snow-covered environment, making ice extremely fast, and has undertaken a large part of the workload.
   "Sir, let's fill in a few big pits in succession, how many more do we need to fill?" An engineer dropped a big block of ice and asked when he looked at the fat leader.
   "Yes, it's too cold. I move ice cubes every day and my hands are frozen."
  Other engineers also turned their heads.
  It doesn’t matter if you are tired these days, but this side of the mountain is not as good as the other side of the mountain, and those people who are used to staying in the north are also cold enough.
  At night, he could barely fall asleep when he was squeezed into a pile on fire. A soldier came out of the tent to pee and fell. When he was found in the morning, he turned into a popsicle.
   "How much to fill?" The tall and fat legion smiled, his expression suddenly stunned, and looked at the engineers and said: "Until it is finished! You have to keep filling it without the order to retreat!
  I'm just afraid of being cold? Next, the brothers who went to the front line to hedge against the undead, but tied their heads to the waistband! You must remember that although we have never fought in the North, you are still soldiers! If the Legion of Undead crosses the Gus Mountains, your family will die at the hands of those demons! "
  All the engineers bowed their heads, showing shame.
  The engineer who had interrogated earlier silently picked up a large block of ice and walked towards the ice wall.
  All the engineers worked silently, their legs and feet were even faster than before.
On the mountain, Dominic in battle armor nodded slightly, retracted his gaze, and looked at the adjutant next to him, saying: "Let the engineers of each legion step up to the front line. Priority is given to the supply of food and grass. The front line must be arranged in accordance with the requirements within three days. "
   "Yes, Marshal!" The adjutant nodded, hesitated, and then said: "Marshal, there is a small matter I want to report to you."
"Say."
   "A frost dragon appeared on the front yesterday. She assisted the Corps to repair more than a dozen gaps, but she has been inquiring about the Undead Legion," the adjutant said.
   "Is it her?" Dominic frowned. "Where is she now?"
   "I don't know if I have already left, I'll go and ask about it." The adjutant said quickly, and walked away quickly.
   Soon after, the adjutant returned and looked at Dominic and said: "Marshal, she has already left, it is said that she flew into the ice field."
"Into the ice sheet?" Dominic's face sank. During this time, the Los Empire broke a lot of spies in the ice sheet. Whether it is an extremely dangerous environment or a skeleton man hidden under the ice and snow, it is extremely dangerous. .
   "Be prepared, I want to write to the Dragon Race." Dominic said.
"Yes!"
  ……
  "If the Million Undead Legion is a flood, then the Baili Mountain Line of Defense is the first flood prevention.
  However, it is impossible to block the flood light. Such a turbulent situation will inevitably overturn the flood protection and cause uncontrollable.
  So I left three spillway outlets. These three spillway outlets are three natural canyons with a length between ten and fifteen kilometers.
  Then at the end of the flood channel, pull the last gate to ensure that no drop of flood will escape. "
  Meg sat on the back of the Griffon, overlooking the vast ice and snow world below. The Gus Mountains were like a huge flood protection, blocking the cold from trying to go south.
   "What if you can't stop it?" Irina asked.
   "There is no if." McGonagall shook his head and said with deep eyes: "We can only guarantee that there will be no accidents."
