Nearly 200,000 annihilation units, plus more than fifty supremes, made both the ice sculpture area and the blue ice fortress feel the pressure.

The Annihilation Legion will be able to reach the border in about three days, Zi Ling will bring more than 5,000 white elf robots to support, and the ice sculpture area has also sent a force of 100,000 people, including more than a dozen supreme powerhouses, and the temporary command center will be established quickly, and the information will be collected one by one.

The Blue Ice Fortress also sent the Supreme, the Little Dragon Girl, two Ice Warriors, and the Little White Fox, four Supreme Strongmen.

Compared to the Ice Sculpture Zone, the number of Supremes in the Blue Ice Fortress is too small.

"No...... We have to find a way to improve the combat effectiveness of the team, otherwise the border will not be able to be defended! Sitting on the sofa, Xi Lingchen rubbed his head with a headache, although he was in the rear, the intelligence on the front line would be sent through the relay tower, and after learning the number and combat power of the annihilation troops, he realized that the situation was not good.

Borders are important and cannot be lost.

"Commander, you can upgrade the Dark Matter Collector." On the single sofa next to her, a blonde elf hugged the data terminal and said, she is an assistant robot created by Xiling Chen, responsible for handling various things such as the mechanical corps, and has no combat power, but the computing system is very powerful.

She has no name, only a code name.

Lyra-01

"Commander, you can only upgrade your equipment in a short period of time, and there is no other way for the time being."

"Hmm...... Let me think about it. Xilingchen didn't agree, because upgrading the dark matter collector might cause annihilation alert, the current battle is only within the rules, once annihilation ignores the rules, then the situation will get out of control.

To improve the combat effectiveness of the front-line troops without arousing annihilation vigilance, even Xilingchen couldn't think of a good way, the main thing was that there was not enough time, and the annihilation legion was dispatched too quickly, and there was no chance of development at all.

"How much dark alloy can you produce per day?"

"Three sets of inner armor, or half a set of custom dark alloy armor." Lyra-01 said.

Too little......

The improvement brought by the dark alloy armor is very huge, the king-level strong equipment can fight against the Supreme, the current commander Zi Ling has the dark alloy armor, although she is level eighty, but it can completely fight against the annihilation units below level ninety-five.

"First increase by ten percent, and in addition, all the recent dark alloys will be used to make armor, and the supreme-level combat power will be armed first." The dark matter collector was only arranged a few days ago, and now it is promoted, which is a bit too fast, but there is no way, the situation on the front line does not allow the mechanical legion to develop slowly.

With the order given, the plant began to be upgraded.

Xiao Ling had been monitoring the annihilation energy and making sure that there was nothing wrong with it, and the factory began to be upgraded.

Xiling Chen returned to the workshop, he wanted to continue to build king-level war robots, and Ziling's success made him find a way, that is, to use some bloodlines to improve the potential of robots.

……

Blue Ice Fortress Frontier.

The teams of the Ice Sculpture Zone and the Blue Ice Fortress have temporarily built seven defensive lines to monitor an area more than thirty kilometers long, and the border area is more than forty kilometers long, and the terrain here is so complex that even the Annihilation Legion cannot advance in a straight line.

Perhaps a high-level powerhouse can climb mountains and mountains, but most of the members of the legion are around level 60, and there is no way for an annihilation unit of this level to cross dangerous terrain.

The construction teams of both sides were built from their respective border areas and eventually converged in the middle.

The Annihilation Corps arrived three days later, but instead of taking action, they set up camp on the flat terrain on the periphery, and the Annihilation units also needed to eat, and they also needed to fight against the cold and cold of the Ice and Snow Country, and the long march would affect the overall combat strength, but it was estimated that the attack would be launched after a day of rest.

With the supreme powerhouse in charge, missiles and the like can't beat it.

There were many weapons of mass destruction in the Magic Age, but very few of them could play a role, and most of the missiles were aimed at high-level targets, 70, 80, or even 90.

High-altitude drones provide information on the Annihilation Legion, and the Supremes of the Ice Sculpture Zone and the Blue Ice Fortress are also on standby in various temporary defense lines, and the number of Annihilation Supremes is large, and the other party may act separately, some attract attention, and some lead the team to fight guerrillas.

And the situation was the same as guessed, and at noon the next day, the Annihilation Legion had an operation.

First of all, the king-level powerhouse led the team to explore the terrain of the border area, and the white elf machinery of the mechanical legion was dispatched to intercept and buy time for other defense lines.

White elves are mechanically capable of flying and can ignore terrain.

At the beginning, the attack of the White Elf Machinery caused a lot of casualties to the Annihilation Team of the Pathfinder, but with the dispatch of the Supreme Strongman, the White Elf Machinery also suffered casualties, and the Purple Spirit immediately recalled the frontline team when he received the situation.

The Annihilation Legion followed behind the pathfinder troops, approaching the defense line little by little, a total of seven defense lines, three of which had the greatest pressure, at the junction of the Ice Sculpture Area and the Blue Ice Fortress, the Supreme of the Ice Sculpture District, and the Little Dragon Maiden were all on these three defense lines.

Two defensive ice sculpture areas are in charge, and one defensive mechanical corps is in charge.

As the Annihilation Legion approached the defensive area, the missile positions and rocket artillery positions of the Blue Ice Fortress carried out a wave of tentative attacks, this time mainly to attract the supreme in the Annihilation Legion.

There are also flying units in the Legion of Annihilation, but they are few in number and rely mainly on the Supreme.

A round of missile bombardment, sure enough, forced out the annihilated Supreme, the number of the opponent's supreme is really problematic, there is a part of the supreme should be hidden in the exploration team, it may pass through the gap in the defense line, causing casualties to the supply line in the rear, although I guessed this, but there is no way at all.

"Chiyo Shizuryu, Xiaobai, you lead the team, patrol the gaps in the defense line, and report as soon as you find the annihilation team." Zi Ling said, pointing to several areas on the map.

"Okay, leave it to us." The two women turned around and left.

There must be a supreme in the defense line of the mechanical legion, and the little dragon girl must not leave, and she cannot leave either.

In contrast, the Ice Sculpture Area was much easier, and the Ice Sculpture Area dispatched more than a dozen Supremes to defend, the number of people was just enough, and even supported several Supremes in the Blue Ice Fortress.

After the Annihilation Legion surveyed the terrain, the offensive began.

A large number of annihilation units charged towards the defense line from all directions, the defense line opened the barrier, and the intelligent machinery inside used long-range weapons to defend, and the supreme powerhouse also appeared at this time, Xiaolongnu and Zi Ling immediately greeted it, preventing the opponent's supreme from causing damage to the defense line.

It was a makeshift defensive line, with only a few magic tanks and portable sentry turrets, after all, it was only three days, and there was no way to perfect the defense of the camp.

Now it's time to procrastinate and buy time for the construction teams on both sides.
