Lin Xian turned and walked away, saying, "Repair the carriage that was just pierced."
Those Snow Demons seem small in size and are easy to eliminate, but the problem is their sheer numbers, and they move swiftly. The tail spikes on their bodies can still cause some damage to steel armor, which is indeed a troublesome headache.
This is still during the daytime; once night falls, as the intelligence suggests, these things will enter a berserk mode and become even more reckless. At that time, with so few people on the Infinity train, facing a full-scale encirclement might lead to situations where taking care of the head leaves the tail unguarded. If the carriages are breached, the loss won’t just be minor.
"The outer layer of the research carriage uses Nitriding Steel + Boron Carbide Ceramic Layer + Self-Healing Gel Interlayer, which is technology from interstellar aerospace. You might consider this type of armor upgrade."
In Carriage 4, Ding Junyi was observing whether the planted plants were affected by the infiltrating snow wind when she saw Lin Xian repairing the armor outside carriage by carriage, so she spoke up.
"It’s not that simple."
Lin Xian focused on his work and said, "What’s inside is flashy but not practical. Facing those monsters, heavy armor is still needed for resistance. The internal upgrades are far less important than the external armor."
Ding Junyi adjusted her glasses and said, "As far as I know, the advanced armor steel used by the military now is mainly Type I and Type II Tungsten-titanium alloys. For mechas, it’s primarily supercarbon carbide alloys and nano-ceramic armor used for individual soldiers. Perhaps these materials will interest you."
Lin Xian became intrigued when he heard this and looked at her, "Director Ding, your knowledge is quite extensive. You’re right, if these materials can serve as a foundation, the external armor protection of the Infinity will certainly rise to another level."
Lin Xian currently has no molecular scans for these materials, so the Preparation Center cannot transform them. But even if they had them, transforming such high-grade materials is time-consuming, labor-intensive, and resource-draining, not to mention Lin Xian’s plan to use them to create the entire train’s external armor.
So, besides the key issues of blueprints, mechanical manufacturing, and Mechanical Devouring, the material problem also started becoming significant for Lin Xian.
The Infinity used to only need some forged steel, titanium alloy, high manganese steel, and high hardening tungsten steel. These materials could be managed by devouring cars, trains, or some large man-made mechanical objects. But Tungsten-titanium alloy, Lin Xian first obtained from the disassembling of a damaged ’Iron Guard 3’ military assault mecha, which he used in critical structures like the GK03 electric knife and Ice-breaking Shield.
So to obtain this type of material, he must find higher-end items to devour. Cars and trains can no longer solve the big problems, and can only be converted into ammunition and weapon materials.
Amidst the blizzard, the Infinity raced along the cold tracks with a roar, as a large number of Snow Demons gathered again in the snowfield, making a boiling Shasha sound as they followed the train’s movement in the snow layers.
After Lin Xian repaired some internal damage of the carriage, he began to repair and reinforce the external armor to some extent. Additionally, shooting ports were opened after the battle started, causing the automatic explosion-proof doors to open and the entire carriage’s temperature to plummet. To preserve the carriage’s temperature, Lin Xian set the passage gates between Carriages 3 and 4 to automatically close after passage.
The living carriages behind, however, had no solution; cold wind invaded through shooting ports, turning the living area’s temperature into an icy snow land. Many teammates who fired had their hands frozen stiff. As a result, everyone in the carriage began to put on thick body heat maintenance devices and cold proof clothing, waiting for the night to fall.
"Lin Xian, we’re almost there!"
In the cockpit, Chen Sixuan looked at the large, continuous hills in the distance ahead in the snowfield, now covered with snow and frost. The Uliyasatai Mountain is a ring-shaped hill feature, with the highest peak only a few hundred meters. When the Palma Prairie had not been covered in heavy snow, it was a place of absolute beauty. But now, only grand, towering snow hills could be seen.
