Chapter 3367

The fortress was successfully promoted to T0 rank, and four types of rewards appeared. If possible, Su Xiao would choose all of them, but unfortunately, he could only choose two.

First was the new organ "Greenhouse" of the fortress. The detailed introduction of this option was only one sentence: it could accelerate the cultivation of soldier-type units.

A simple analogy was that if a female boar-headed person was pregnant, the original process of 10–11 months of pregnancy would take about a month if the female boar-headed person was in the "Greenhouse."

If Su Xiao were a person of this world, this ability would be a must-choose. A stable population source was the foundation for building a faction. But he wasn't, and furthermore, he had no interest in building a faction. What he was building was a legion purely for war.

Reward 2 was a 45% increase in the active ore conversion amount of the Doomsday Fortress. This was very tempting. Compared to Reward 3 and Reward 4, Reward 2 was not fragrant.

To gain a firm foothold, Reward 3 was a must-choose. The current "Evolution Nest" occupied the second, third, and fourth floors of the Doomsday Fortress. Su Xiao's command center was already on the fifth floor of the Doomsday Fortress, still the top floor, convenient for overlooking the battlefield situation during war.

The area of each floor of the fortress was several times larger than before, which allowed the "Evolution Nest," occupying three full floors of the fortress, to accommodate 5,000 boar-headed men at a time.

Each batch of boar-headed men transforming into wild boar warriors took 2 hours. Choosing Reward 3 would reduce this time to 1 hour.

With enough active ore and the ability to buy enough boar-headed men, the "Evolution Nest" could transform 24 batches of boar-headed men every day, totaling 120,000, and could transform 96,000 wild boar warriors and 12,000 dwarf boar men (digging miners).

Su Xiao chose Reward 3 and Reward 4. Although he couldn't see the specific data, he couldn't refuse the Level 5 troop type.

【Evolution Nest work efficiency has increased by 50%.】

【Evolution Nest has unlocked a new troop type, Heavy Tank.】

【Heavy Tank】

Troop level: Level 5.

Evolution prerequisite: Requires one Level 3 troop type, wild boar warrior.

Evolution success rate: 100% (This evolution is a growth-type buff, not a distortion type, to improve the wild boar warrior's body size, vitality activity, etc., and endow it with formidable biological armor on the body surface until it evolves into a Heavy Tank).

Evolution cost: 5,000 points of active energy.

Heavy Tank characteristics: Large body size, strong defensive armor, vigorous life, charge, anti-knockback.

Note: After evolving into a Heavy Tank, it can still be restored to the wild boar warrior form (it will have some different characteristics from other wild boar warriors). This is an improvement in life rank, not a change or distortion of life nature.

The specific data of the Heavy Tank was not yet known. The cultivation cost of these big guys was very expensive, requiring 5,000 points of active energy each.

The evolution of wild boar warriors into Heavy Tanks was more like having a powerful form, somewhat similar to a transformation skill. The difference was that this was a switchable form, and there was no time limit.

Completing the promotion of the fortress, Su Xiao began to think about development problems. The value of a boar-headed person was 2 kilograms of active ore. Added to the channels Caesar created, as well as the expenses along the way, the value of a boar-headed person reached 3 kilograms of active ore after arriving at the Doomsday Fortress.

Afterward, entering the "Evolution Nest" to transform, the active energy required for each boar-headed person consumed 1 kilogram of active ore.

From purchasing a boar-headed person, transporting it, until it transformed into a wild boar warrior, it consumed a total of 4 kilograms of active ore.

The probability of boar-headed men transforming into wild boar warriors was about 80%. Estimating this way, the 2,830 units of active ore he had could produce 56,600 wild boar warriors.

This was just theoretical data. The actual situation would have slight deviations, but it wouldn't be much different.

With resources in hand, he could start producing troops at any time. Before that, Su Xiao still had one thing to do.

Arriving at the second floor, the scene before him was quite spectacular. The black biological structure of the Evolution Nest occupied over 90% of the space here. Thick meridians were spread all over the Evolution Nest, occasionally squirming slightly.

As the fortress evolved to the top level, the Evolution Nest was the same, but it still had room for development.

The Evolution Nest had a passive characteristic "Instinct Endowment," which was the source of the "Combat Instinct" skill possessed by the wild boar warriors.

Su Xiao now had two choices: through super-biological genes, let the Evolution Nest possess other passive characteristics, that is, let the Level 3 troop type wild boar warriors possess more passive skills.

If he gave up this point, Su Xiao could inject the genes of Zerg combat units into the Evolution Nest, allowing the Evolution Nest to transform into Level 4 troop types.

Simply put, it was whether to stack passives for Level 3 troop type wild boar warriors or try to unlock Level 4 unknown troop types.

There was no doubt that the cultivation cost of Level 4 troop types was higher. Under the circumstances of limited resources, wanting to form a Level 4 troop type legion was a pipe dream.

The total cultivation cost of Level 3 troop types was 4 kilograms of active ore, while Level 5 troop type Heavy Tank required a Level 3 troop type as a basic prime, plus 5,000 kilograms of active ore.

Su Xiao estimated that the transformation cost of Level 4 troop types would be at least 200 kilograms of active ore each.

The number of Level 4 troop types was not as good as wild boar warriors, and their combat power was far lower than Heavy Tanks. Looking at it this way, it was better to stack passives for the wild boar warriors. Perhaps after stacking to a certain extent, the wild boar warriors as Level 3 troop types could match the combat power of Level 4 troop types.

Thinking of this, Su Xiao took out a metal box. After opening it, cold air drifted out. Numerous blood collection bottles, test tubes containing flesh and blood, animal skins with scales, etc., were displayed before his eyes. These were all Su Xiao's collections, coming from many native worlds he had been to.

Morey, who was so bored she was almost counting ants, didn't know when she stood diagonally behind Su Xiao, poking her head to look at the numerous collections on the rack.

"How many big bosses did you kill for this?"

After Morey saw Su Xiao's collections, she suddenly knew why Su Xiao was so strong.

"..."

Su Xiao didn't speak. He looked at a blood collection bottle containing pitch-black blood. This blood collection bottle was about the thickness of an index finger, and the blood inside gave people an ominous feeling.

After hesitating for a while, Su Xiao decided not to inject the divine blood of the Feather God Hegla into the Evolution Nest. This was ancient god blood. If he was not careful, the Doomsday Fortress would wither together.

A touch of golden micro-light attracted Su Xiao's gaze. That light was like the sun. Su Xiao picked up a small bottle of golden blood. This was not obtained through combat, but the soul blood of the Sun Warrior obtained when sacrificing with 【Oath Emblem: White Dragon】.

Su Xiao didn't know how strong the Sun Warrior was, but he had encountered a Sun Warrior one tier lower than the Sun Warrior. That time in the Holy Land of Kiliad, he had defeated the ultimate big boss Rogesh, but he didn't dare to face more than 30 Sun Warriors at the same time.

The characteristics of these items from the Sun faction were roughly close combat, self-healing/recovery, faith in the sun, fearlessness, etc.

Thinking of these, an inspiration surged into his heart. In the previous world, Su Xiao was still in the Sun God Sect and knew that place very well.

Not only that, the Holy Land of Kiliad, which was the ruins of the Sun God Clan, was also inclined toward the divine system and faith system.

Factions related to the sun would more or less have some faith characteristics. After all, the sun was above everyone's head. During the day, looking up, one could see the "Supreme God."

There were too many benefits to believing in the sun. First, the sun was not a divine existence and wouldn't have miscellaneous things. Besides that, the sun represented light, purification, life, authority, and even freedom, etc.

Although the current Doomsday Fortress was not a loose sand, it wasn't much better. After the war started, the wild boar warriors would more instinctively obey orders. Wanting to have fighting spirit or something, that was impossible.

But if he injected the soul blood of the Sun Warrior into the Evolution Nest, letting the transformed wild boar warriors possess the abilities of sun characteristics, and then branded them with the sun's pattern or logo, etc.

Finally, let them believe in the sun. In this way, on the battlefield, morale and fighting spirit would never be low.

By then, it could be declaring war on the enemy with the brilliance of the sun. The Sun Church had a saying: "Child, your sins are too great to be saved. After killing you, this small box will be your eternal home."

Not only that, Su Xiao was even prepared to change the name of the fortress. What Doomsday Fortress, it was unlucky. From now on, it would be called Sun Fortress.
