Chapter 4

The初级 Death Summoning Mastery did not disappoint Lin Han. This time, it directly summoned a third-tier unit - the Wraith, which could be considered a burst of good luck. This was probably the best unit that the current Death Summoning Mastery could summon.

"Wraith: A third-tier level 2 unit of the Necropolis race, an advanced form of the Wraithling, possessing powerful attack and self-healing abilities. Its evasion ability is a nightmare for all physical attackers. Damage: 7-10, Defense: 3, Health: 120, Movement Speed: 2 meters per second, Attack Speed: once every 1.5 seconds. Special Abilities: 1. Ethereal Body [The Wraith has an intangible body, and there is a 33% chance to evade any physical attack.] 2. Rapid Healing [The Wraith has an extremely fast recovery ability, regenerating 3 health points per second.]"

The higher the tier of the unit, the stronger its attributes. The gap between a third-tier unit and a first-tier unit was so great that they were incomparable. Especially since the Wraith was an advanced form of the Wraithling, its combat strength was self-evident.

Overall, the losses from this battle were still within Lin Han's acceptable range. The Skeleton Archers appeared in a relatively rear position, and in this situation, even after dispatching all the Wraiths to absorb damage, he still lost over 50 Skeletons. The main reason was that the enemies this time were not appearing in clusters as before, but in a large mixed group.

Zombies, a second-tier level 1 unit of the Necropolis race, were not highly regarded in the previous life. As a unit with extremely slow movement speed, although they had high attack and health values, they rarely had the opportunity to utilize them. However, the wave of Zombies that appeared this time gave Lin Han a huge headache. Their slow movement speed blocked all the Skeleton Archers behind them, and their high health values made them excellent tanks. Ordinary Skeletons were no match for them.

"Zombie: A second-tier level 1 unit of the Necropolis race, reanimated corpses by necromancers, driven only by the desire for living flesh, they will continue to attack their enemies until they are completely dead. Damage: 5-8, Defense: 2, Health: 80, Movement Speed: 0.4 meters per second, Attack Speed: once every 3 seconds. Special Ability: 1. Rotten Flesh [The Zombie's body is already rotten, and any non-Necropolis unit attacking it will suffer 10 points of poison damage, while the Zombie will take 2 points less damage, with a minimum of 2 points.]"

From the Zombie's data, it was clear that this was an extremely annoying tank. With only 2 points of defense and the Rotten Flesh ability that reduced 2 points of damage, a group of Skeletons would take a long time to take down a single Zombie, while a Zombie could take down a Skeleton in just four or five hits. The entire battle process was a heart-wrenching experience for Lin Han.

"Your troops have cleaned up the battlefield. You have obtained 19 units of wood, 11 units of stone, 10 units of ore, 3257 gold coins, 2 unit cards of Skeletons [50 units each], and 1 unit card of Skeleton Archers [20 units]."

"Damn, there's no unit card for Zombies, that's too unfair!"

Looking at the battlefield cleanup data, Lin Han was a bit disappointed. Zombies were not highly regarded in the later stages, lacking speed and damage compared to higher-tier units. However, in the early stages, especially in defensive battles, having a group of Zombies would make things much easier.

"Beep! Your Skeleton Archers have reached the maximum experience level. If you have a Skeleton Training Ground, you can upgrade them to Skeleton Heavy Crossbowmen."

The first batch of Skeleton Archers had all reached the maximum experience level. If Lin Han could build a Skeleton Training Ground, he could upgrade these Skeleton Archers to Skeleton Heavy Crossbowmen, which would significantly increase their output.

"Please note, the fourth wave of attacks will arrive in 10 minutes. This wave will feature a leader-level creature. Please be prepared."

The sudden notification made Lin Han pause, and he almost cursed. A leader-level monster appeared in the fourth wave? Was this game even playable?!

Others might not know, but Lin Han did. In this game, units were divided into many categories. The initial common units could be recruited directly from the recruitment area. Reinforced and Elite units were upgraded versions of common units, with stronger attack, defense, and health values, all achieved through special buildings. Beyond these, there were also leader-level and legendary units.

Leader-level units, to some extent, had completely transcended the limitations of regular units. They possessed extremely high health and attack values, powerful skills, and most importantly, a large-scale war aura ability.

War aura was originally a hero's ability, but it also appeared in leader-level units. The more powerful the leader-level unit, the stronger its war aura. Combined with their own attack capabilities, these units would be almost like bugs on any battlefield.

"Build the Main Camp!"

Lin Han looked at his resources, gritted his teeth, and said fiercely. Since a leader-level creature had appeared, upgrading the Skeleton Archers was a must. Leader-level creatures had extremely high defense, and without upgrading the Skeleton Archers, they would likely only deal 1 point of forced damage.

"Main Camp upgrading, remaining time: 5 minutes 59 seconds."

The Main Camp's upgrade time was 6 minutes. During this time, Lin Han looked at his buildings and began to consider how to deal with the fifth wave of attacks.

Logically, if a leader-level creature appeared in the fourth wave, the fifth wave would feature 2-3 leader-level creatures, which was quite scary. The city wall was the best defense against enemy attacks in the early stages, but it was not invincible. In front of leader-level units, the city wall's defense was almost negligible.

"Upgrade the Tomb of Research."

After searching through a mess of building trees, Lin Han finally found the building he wanted - the Tomb of Research.

"Tomb of Research: A unique building of the Necropolis race, a place for researching various special abilities, where Necropolis buildings and units can be researched to enhance their strength."

Any Necropolis player could build the Tomb of Research from the start, but few players actually used it, as the research was extremely frustrating.

After issuing the command, a thick fog quickly rose around the large cemetery. Soon, the fog disappeared, revealing a vast cemetery in Lin Han's field of vision. On the cemetery, several large tombs glowed with a dark light.

Entering the nearest tomb, a frail-looking Necromancer appeared before him. "Respected Lord, this is the Tomb of Research. Is there anything I can assist you with?"

"How many resources are needed to upgrade the city wall?"

Although the Necromancer looked frail, he was actually a sixth-tier unit of the Necropolis race. Of course, this was an NPC for players, with no combat ability, just the appearance of a Necromancer.

"Upgrading the Basic City Wall to the Basic Granite City Wall requires 20 units of wood, ore, and stone, and 5000 gold coins. Lord, do you wish to upgrade?"

Upon receiving Lin Han's inquiry, the Necromancer quickly reported a number that made Lin Han's mouth twitch. 20 units of wood, ore, and stone were the most resources Lin Han could currently afford, and 5000 gold coins! This was the most critical part. After several battles, Lin Han had only saved a bit over 6000 gold coins. Upgrading the city wall once would leave him almost penniless, and it would be a lie to say he wasn't heartbroken.

"Upgrade it."

Although Lin Han had been prepared for the Tomb of Research to be frustrating, he was still a bit disappointed when he was actually cheated. However, when he saw all the city walls glowing with a dark light, his mood improved a bit.

"Basic Granite City Wall LV2: Defense: 20, Armor Type: Reinforced Armor [Reduces all attack damage by 40%.] Durability: 1500/1500. Special Ability: Magic Resistance [A city wall built with granite can reduce all magic damage by 30%.]"

The Basic City Wall at LV2 had 15 defense and 800 durability. After upgrading to the Granite City Wall, it gained 5 more defense and 700 more durability. However, the most important thing was the Magic Resistance ability, which was crucial for countering leader-level units.

"Your Main Camp has been built. All units below the fifth tier in your town will have their base production increased by 5 units."

The completion notification made Lin Han immediately happy. He quickly walked to the Bone Land and, as expected, found an upgrade option in the Bone Land's menu.

"Bone Land Upgrade Option - Upgrade to Bone Training Ground. Required resources: 25 units of ore, 45 units of wood, 50 units of stone, and 4000 gold coins."

This was the cost of upgrading the Bone Land to a Bone Training Ground, but Lin Han didn't need to pay it. He had the building blueprint.

Taking out the Bone Training Ground blueprint, it glowed with a dark light in Lin Han's hand and floated in the air.

"Beep! Do you want to upgrade the Bone Land to a Bone Training Ground? Note that once upgraded, it cannot be reversed. Players can choose to cancel the upgrade, but the consumed blueprint will not be returned."

"Upgrade!"

Having spent so many resources to upgrade the Main Camp, Lin Han was determined to make this choice. There was no need to think twice!

"Upgrade successful! Your Bone Land has been upgraded to a Bone Training Ground. You can upgrade Bone units that have reached the maximum experience level to more advanced forms here."

As the notification sounded, a thick fog enveloped the Bone Land. When the fog cleared, the Bone Land, which was previously covered in bones, suddenly had a cave glowing with a dark green light. As Lin Han approached the cave, he received a notification: "Bone Training Ground. Do you want to upgrade your troops to a higher form?"
