After the arrangement of the two children, MEG and Elena go all the way north and come to the north again.

However, compared with previous times, this time they did not cross the gus mountains.

MEG asked Azzi to lower his altitude and fly over three grand canyons.

A large number of engineers, like ants, are busy in the canyon. They need to repair both sides of the cliff to prevent skeletons from climbing up easily, and dig a tunnel several meters high in the middle of the canyon.

There are also a considerable number of magicians in the canyon, who are carving arrays on the cliff and the ground.

These three ten mile long canyons will become the meat grinder of this war.

McGonagall will lay heavy troops on both sides of the canyon. Before they arrive at the mouth of the canyon, they will try their best to kill the undead Legion and relieve the pressure on the soldiers who defend the mouth of the canyon.

"Although there are a lot of engineers, their efficiency is too low, and they need to send elite with special ability from all ethnic groups to help." McGonagall frowned and said that the northern border corps had limited ability to meet his requirements.

"When the night elves arrive, they can join the team that engraves the array. The number of magicians is more than 1000." Said Irina.

"Not enough." McGonagall pointed to the ice sheet ahead. "If I can, I hope to kill them as much as possible before they reach the gus mountains, so as to reduce our losses."

"Our time is limited." Elena reminded.

"I'm greedy." McGonagall takes back his eyes and asks violet to fall.

The temporary headquarters of the coalition forces was set in the middle of the battle line, adjacent to the Grand Canyon in the middle. On a platform at the top of the mountain, several halls made of ice blocks were temporarily built.

Crystal clear ice, shining in the sun, looks like a dream of ice castle.

The endless supply of ice in the north is the best building material.

Only a few simple arrays need to be depicted inside to block the chill of the ice itself and the influence of internal activities on the ice.

The purple Griffin landed on the platform in front of the hall. After a short panic, the guard recognized Meg's identity and saluted.

"Is Marshal Dominic in camp?" McGonagall jumped out of the Griffin and looked at an officer who was coming quickly.

"The marshal is in the camp. Please follow me, my Lord." The officer replied respectfully, leading MEG and Irina ahead.

There is no splendid decoration in the ice hall, which is divided into several areas like the Ministry of war. Civil and military officials are busy handling affairs.

At present, the Allied forces of all ethnic groups have not yet arrived at the front line, and the front-line camp is still dominated by the Imperial military team led by Dominic.

The officer led MEG and Irina to a conference hall deep in the hall. The wide conference hall still had no extra decoration. The round table was arranged around a huge sand table. The sand table was a replica of the terrain of the front line of the Los mountains, including the three canyons.

Dominic is writing something at his desk. When he hears something, he stops writing. He gets up and looks at MEG and says, "here you are."

"Yes." McGonagall nodded, looked at the sand table, then looked at Dominic and said, "the difficulties on the front line are more than I imagined."

Dominic's wrinkled face showed a smile. If the engineers on the front line could hear this, they would be very happy.

"The Corps can't finish the front line work in a short time. They can't do many things. The magicians of the mage tower, let them come to the front line immediately." McGonagall looked at Dominic and said.

"I also want to ask the ice dragon clan to help repair the gaps in the gus mountains. Some of the gaps are too big for engineers and magicians to fill in for a while." Said Dominic.

"I will order all ethnic groups to help immediately. The front line fortifications are the key to this war and must be completed quickly." McGonagall nodded, which he had thought on the road before.

At present, all ethnic groups are gathering elite troops, but it will take a lot of time for such a large-scale army to go northward even if it has a green light.

At this time, McGonagall thought of the benefits of a large transmission array.

Unfortunately, the cost of the layout and use of the transmission array is very high, let alone the super large transmission array with a population of more than 10000 people. Now all ethnic groups in Nolan can't afford to play.

But frontline fortifications need people with special abilities, such as powerful ice magicians and ice capable people, who can speed up the repair of the gap.

There are also array mages. Every additional array in the canyon can reduce the pressure on the soldiers in the rear. It's of great benefit to arrange it in advance.

Dominic nodded, which happened to coincide with him, but his identity is not enough to mobilize all ethnic groups, Alex can take the initiative to put forward, naturally it is the best.

"By the way, there's one more thing you might be interested in." "Yesterday, an ice dragon visited the front, helped fill more than ten gaps, inquired about the Legion of the dead, and then left early to enter the ice sheet," Dominic said

"Elizabeth?" McGonagall asked, looking at Dominic.

"From the description of the front-line soldiers, it's likely to be her." Dominic nodded.

"Where exactly did she enter the ice sheet?" McGonagall asked with a dignified look.

"You're going into the ice to find her?" Dominic looks at MEG in surprise.

"She's important." McGonagall nodded and added, "maybe it could be a trump card against frankster."

After searching for so many days, it was the first time MEG had heard from Elizabeth.

The bad news is that she's in the ice, and it's in the morning.

"I asked the soldiers who saw her leave in the morning to come." Said Dominic.

"No, just find someone to take me there. I'm afraid it will be different in another place." MEG shook his head.

"Good." Dominic called the adjutant and asked him to take MEG and them to the soldiers who had met Elizabeth.

Irina also followed MEG with a dignified look. The ice sheet was in danger. Both kesuru and Joe were extremely dangerous.

And even if she finds frankster, who has lost her mind, it is even more dangerous.

Soon, McGonagall met the engineering regiment that had met the ice dragon.

From their description, McGonagall can confirm that it is Elizabeth, who has disappeared for a long time.

"My Lord, she's flying in this direction. I'm sure." A tall and thin engineer reached out and pointed to the vast expanse of ice.

"Before she left, did she say where she was going?" Asked MEG.

"No, she didn't speak much. She only asked a few questions about the Legion of the dead, but we didn't know anything. We didn't give her any information." The soldier shook his head.

"Good." MEG nodded, looked back at the adjutant who had brought them, and said, "tell Marshal that I need to go into the ice field, and let him write the letter."
