The Annihilation Legion has not yet discovered the city wall construction plan, the city wall of the ice sculpture area is built from the inside out, and the city wall on the border of the Blue Ice Fortress is protected by a large number of troops, all the annihilation units that have been detected in the past have been killed, and the city wall area has been arranged with a concealed formation, which is difficult to find unless it is a supreme-level powerhouse.

In the early stage of construction, it was difficult to discover, and even if it was discovered, there was no way to attack it if it was annihilated, and the terrain was too complicated for conventional troops to pass.

There are more than 200,000 annihilation legions that came over this time, and the number is not many, as long as the annihilation does not reinforce and the three lines of defense on the front line are not breached, it can be consumed forever.

At present, the most scarce thing is time, it takes time to build the city wall, and it also takes time for the machine factory to expand.

The first wave of the offensive of annihilation ended after half an hour, and the three lines of defense were held, although there were casualties, but there was no impact on the defensive line, but this was only the beginning, annihilation would not let everyone rest, this attack was just a test.

"Send the injured sister away, and the others continue to be on alert." Zi Ling leaned back on the armored car, looking at the potholed ground outside the defense line, this time he lost more than a dozen sisters, and there were hundreds of casualties, although they were all intelligent machines, but to Zi Ling, they were like sisters.

The setting is like this, all white elf machines are sisters, and there will always be casualties in war, and there is no way to avoid it.

The transport plane sent the injured White Elf machine to the repair center in the rear, and it could be repaired in a day if it was fast, and it would take two or three days if it was slow.

Xilingchen, who is far away in the industrial city, also received the news that he has not created a new advanced artificial intelligence in the past few days, but is designing a new class, a class suitable for fighting in the snow.

Code: Ice Crystal Intelligent Machinery.

Humanoid intelligence, very weak compared to the white elf intelligent machinery, unable to fly, has very low defense, and has only thirty levels of combat power in close combat, but is proficient in various firearms, can use various long-range weapons, and is a long-range class of defense and assault type types.

No dark alloys are used, and no particularly high-grade metals are used, this is to reduce material consumption, the White Elf Intelligent Machinery belongs to the elite, and the Ice Crystal Intelligent Machinery belongs to the mass production type of ordinary units.

"Check it, and if there's nothing wrong, make a thousand first." Xilingchen said to the intelligent system in the workshop.

After hearing this, the intelligent system asked, "What type of manufacturing?" ”

"Two hundred snipers, all the rest are made assaulters, let the factory produce magic assault rifles, use physical bullets, the level and strength of the sniper rifles are increased a bit, you watch the distribution of bullets." Xilingchen stretched, and then walked towards another full-range screen next to him.

All the weapons and equipment here were designed by Xiao Ling and him himself, using materials that are available in the Ice and Snow Country.

Coming to the screen, this is a new super artificial intelligence, and unlike Zi Ling, this one in the design is a sniper, and he is a very powerful sniper.

There are too many Supreme Powers of Annihilation, and this sniper is to target the Supreme of Annihilation, close to level ninety combat power, with top-level hidden modules, using a ghost sniper rifle, codenamed Scorpio.

Scorpio is still in the design stage, because there are many parts that cannot be manufactured in mechanical factories. Institutions

More than 1,000 ice crystal intelligent machines were manufactured three days later, and after they were manufactured, the transport planes sent new troops to the front line, followed by several factory assistants, who were responsible for collecting various data of the new troops, and then improving the ice crystal intelligent machinery according to these data.

The cost of the Ice Crystal Intelligent Robot is very low, and the materials used are common near the industrial city, even if they use rare resources.

As long as there are resources, machine factories can manufacture in large quantities.

Ice Crystal Intelligent Machinery needs to team up with the White Elves, if there is no one to protect, a level 60 annihilation unit can cause a large number of casualties, at the beginning, the Ice Crystal Intelligent Machinery has achieved good results, with strong long-range firepower, it has repelled several attacks of annihilation, but after the annihilation is reflected, it is targeted.

In just two days, more than 300 Ice Crystal Intelligent Machines were destroyed, and the White Elf Force also suffered casualties due to protecting the Ice Crystal Intelligent Machinery.

The shortcomings of the new class are reflected in this way, but compared to the firepower of the Ice Crystal Intelligent Machine, the shortcomings are nothing.

After Xilingchen knew the situation, he designed a portable shield belt, this kind of shield can block the attack of the sixty-level powerhouse, in addition to the shield, Xilingchen designed another class, codenamed Tiandun Seat, a defensive type of intelligent machine, almost no attack power, the only ability is to unfold the shield.

Like Scorpio, this class is not something that can be created in a short period of time, but only a design file is built.

Xiling Chen is currently at the supreme level, if he goes to the front line, he will definitely be able to affect the local battlefield, but the number of annihilation units is too much, even if there are many kills, it will not have a role in the overall situation.

Decisively and honestly building in the rear, he can rub some parts by hand, which can play an important role in the manufacture of factories and even robots.

The shield belt was equipped with the ice crystal troops two days later, and with the shield, the casualties were obviously much smaller, and the annihilation troops had to pay a very big price if they wanted to destroy the fierce ice crystal troops, especially Zi Ling had a plan to let the ice crystal team use the bait to design traps, and even killed several supreme powerhouses.

The attack of the annihilation troops was fierce and almost uninterrupted, and the 1,000 ice crystal troops lost more than half of them in less than five days.

The core intelligence of the Ice Crystal Force is not bad, and it can be revived as long as it is recovered.

Up to now, the factory assistants sent to the front line have collected a large amount of data, which is transmitted back to the machine factory, and the new generation of ice crystal troops will improve according to these data, and a large number of them will start post-manufacturing in two days, and in addition to the ice crystal troops, the Sky Shield intelligent machinery has also produced more than a dozen members.

These dozen or so people will be sent to the front line with the new generation of ice crystal troops, and when the time comes, they will be adjusted according to the battlefield situation, and these adjustments do not need to be set up by Xiling Chen himself, and the intelligent system in the workshop, plus the assistant Lyra-01, can be solved.

Xilingchen mainly designs the drawings of intelligent machinery, as long as there are drawings, relying on the computing core of the workshop, it can be completely transformed independently.

Seven or eight days later, bad news came, the Annihilation Legion was moving, and the rear was assembling.

The battlefield in the border area is in a stalemate stage, if the annihilation support is at this time, it will definitely not be able to hold, this information is transmitted from the ice sculpture area, the blue ice fortress sent dozens of high-altitude drones to investigate, and finally determined the accuracy of the news, the annihilation troops are really gathering, and there are still large creatures in the assembled troops.
