70: Chapter 70 The Terrifying War Machine, Level 4 Lord's Mansion

At night, General Li Xin led the troops back to the territory successfully.

Although they did not encounter any attacks along the way, the Scout soldiers sensed they were being followed.

Moreover, those tracking them were very likely Insect Swarm reconnaissance units.

They possessed powerful senses of smell and anti-reconnaissance capabilities, to the extent that the Scouts could only find traces but could not track down the targets.

Su Yang was not too surprised that the Insect Swarm had evolved reconnaissance units; the Insect Swarm had always been in a state of evolution.

However, the current gap in strength between the two sides could no longer be bridged by a few Scout insects.

Furthermore, with the Level 2 walls and the upgraded Imperial Armor Legion, it was useless for these insects to Scout until their brains broke.

While deep in thought, Su Yang invested command points into the Imperial Armor Camp.

Regardless of the extent of the Insect Swarm's evolution, the top priority was still to improve his own strength.

Upgrading the remaining 20 Armored Elite Soldiers and 20 Armored Crossbowmen required a total of 28,000 command points.

The current total of command points was 33,842, and after everyone was upgraded, there would be just enough to summon two additional Skyfire Guards.

It was simply a perfect allocation!

[command points - 32,000]

[Level 3 Great Qin Armored Elite Soldier upgrading...]

[Level 3 Great Qin Armored Crossbowmen upgrading...]

[Great Qin Skyfire Guard summoning...]

With the command points invested, the upgrades were completed quickly.

40 Level 3 Armored Elite Soldiers, 30 Level 3 Armored Crossbowmen, and 4 Great Qin Skyfire Guards.

The Imperial Armor Legion had reached its current maximum Rank!

With everyone at maximum Rank, a sense of fulfillment surged in Su Yang's heart.

The army's upgrades were complete, and the next step was to set off for the ruins to seize this temptation right at his doorstep.

However, considering the current intelligence level of the Insect Swarm, it was necessary to upgrade the defensive measures in advance.

The defensive building brought by the Level 3 Main Base was the skyfire tower.

Unlike the ballista tower built on the city wall, the skyfire tower was an independent building.

Building a skyfire tower required 80 units of iron ore resources and 30 units of copper ore resources.

Su Yang opened the resource panel to check in detail the current stock and production speed of each resource in the territory.

The "Peace and Prosperity" BUFF disappeared last night, and now only The Progressive's 20% bonus remained.

[Territory Resources]

[Water Resources: Stock: 763 units, Production Speed: 300 units/day (20% bonus)]

[Stone Ore Resources: Stock: 456 units, Production Speed: 180 units/day (20% bonus)]

[Coal Resources: Stock: 563 units, Production Speed: 255 units/day (20% bonus)]

[Copper Ore: Stock: 269 units, Production Speed: 180 units/day (20% bonus)]

[Iron Ore: Stock: 286 units, Production Speed: 150 units/day (20% bonus)]

[Saltpeter Resources: Stock: 21 units, Production Speed: 75 units/day (20% bonus)]

According to the panel, the resources within the territory, both in terms of stock and production, were above the subsistence level.

This was the situation a lord liked to see most: strong troops at the front and sufficient supplies at the rear.

With a flicker of his thought, Su Yang invested 80 units of iron ore and 30 units of copper ore to build the skyfire tower.

Judging solely by the resources invested, the skyfire tower was definitely a big guy.

[Iron Ore - 80]

[Copper Ore - 30]

[skyfire tower is under construction]

Boom— The blueprint was set, and the sound of machinery roaring to life echoed.

A metal turret rose from the ground.

The base of the skyfire tower was a 5-meter × 5-meter metal platform.

Above it, cylindrical metal barrels of varying sizes were nested into one another.

The upper barrels gradually became smaller on the whole, but the final muzzle section was slightly larger than the middle section of the barrel.

The muzzle diameter was even larger than those on the Skyfire Guard's shoulders, reaching nearly 1.5 meters.

The massive vertical cannon barrel was connected to the largest cylindrical metal base at the bottom by a dozen horizontal metal rods.

These rods could adjust the direction of the muzzle through expansion and contraction, and on the outside of the cylindrical metal platform were four huge ammunition compartments.

The attack method of the skyfire tower was no different from the Skyfire Guard; both projected artillery shells.

The shell types were also completely the same: the area-of-effect Skyfire Bomb and the single-target high-explosive shell.

Their only difference lay in the caliber; the explosive stones fired by the skyfire tower were a full three times larger than those of the Skyfire Guard.

The damage range of each shot was more than double, and the fuel consumption was more than four times greater.

This was a terrifying war beast, and also a bottomless pit for fuel.

Unless necessary, it was best not to activate this Skyfire Cannon.

The attack range of the Skyfire Cannon was 3,000 to 8,000 meters; there were restrictions on both the maximum and minimum distances.

The maximum limit was due to the range reaching its upper limit, and the minimum limit was because if it were less than 3,000 meters, the explosion of the shell would affect the friendly buildings.

Like the ballista tower, using the skyfire tower required a professional gunner.

That is to say, to activate the skyfire tower, one must ensure that a Skyfire Guard was present.

Looking at the massive body of the skyfire tower, Su Yang could imagine what a spectacular scene it would be when it fired.

He had thought the shock the Skyfire Guard brought him was intense enough, but he hadn't expected that the real heavy-hitter was still to come!!

Su Yang felt that this thing was no longer just a simple matter of sending the Insect Swarm to meet their great-grandmother.

If necessary, it would be no problem for him to shoot the great-grandmother down from the sky to meet her insect grandchildren.

After experiencing the shock of the Skyfire Cannon, Su Yang opened the panel again and switched to the lords residence option.

All troop types and combat technologies had finished upgrading, so it was time to put the Level 4 Main Base on the agenda.

[Main Base: lords residence]

[Rank: Level 3 ＞＞＞ Level 4]

[Unlock Level 4 resource devices, Level 4 defensive facilities, Level 4 research buildings, Level 4 Imperial Armor Camp, and obtain new hero buildings]

[Upgrade Requirements]

[Coal Resources: 500 units]

[Copper Ore Resources: 500 units]

[Iron Ore Resources: 1,000 units]

[Stone Ore Resources: 1,000 units]

[command points: 20,000 points]

[Time: 4d]

The greatest temptation of the Level 4 Main Base for Su Yang was the new hero buildings.

Whether it was the Foundry under the Heavenly Artisan or the Astrology Tower under the Tactical Aide, both could bring great assistance to the territory.

Especially the Foundry, which could unlock weapon research, upgrades, and exclusive Imperial Armor modification techniques.

Su Yang had been craving this effect for a long time.

Once unlocked, he could modify and customize weapons for individual Imperial Armor units.

By then, he could craft a set of Imperial Armor for himself to improve his safety and reduce his reliance on other soldiers.

However, the main purpose was still to modify General Li Xin and other general-level units.

Ordinary humans, and even General Li Xin's Physical Body capabilities, were limited.

But as long as technology continued to develop, the capabilities of the Imperial Armor would be limitless.

Through constant modification and upgrading of components, he could create absolute individual combat power with no upper limit!
