Chapter 141: Undead Energy Altar

“Three Strength Gems, four Agility Gems, one Constitution Gem…”

Xu Feng was speechless as he looked at the Silver Treasure Chest before him. Inside the chest, there were no other items, only a whole set of Attribute Gems. From Strength Gems to Perception Gems, all five types of attribute gems were there, with more than a dozen appearing at once.

This phenomenon of a large number of the same attribute items dropping all at once was very rare. In his past life, Xu Feng had only encountered it once. That time, he opened a Bronze Grade Treasure Chest in the wild and got over a dozen Bronze Grade long swords. Although they were only worth a few thousand Fate Points, the sight of so many items covering the ground was still very pleasing and made him happy.

After splitting the Attribute Gems equally with Ding Xiang, the two continued to explore the wilderness.

This Ancient Castle covered a large area, but it was not very tall. From the outside, Xu Feng estimated it had only three floors.

Now, this wilderness was likely the third floor of the Ancient Castle, or a Demiplane connected to the third floor. The way to leave the Ancient Castle must be within this wilderness.

The two continued to go deeper. There were many Skeletal Knights in this wilderness, all of them Three-Star Elite Monsters. The two slowly lured the monsters, killed them, and moved forward. Dozens of Skeletal Knights had already fallen before them.

Ding Xiang’s Undead Giant finally ran out of Health Points and collapsed, replaced by a Skeletal Knight. Now, the undead pet following Ding Xiang had become two Skeletal Knights, each with only half of their Health Points left.

With Ding Xiang’s undead pets acting as shields, Xu Feng maintained a high efficiency in killing monsters. The dropped Fate Treasure Chests, besides more than ten Three-Star pieces of equipment, also dropped three Forging blueprints, two potion recipes, and over a dozen Attribute Gems.

Most of the more than ten Three-Star pieces of equipment were Silver Quality, with three Bronze Grade pieces and one Gold Quality piece. Among the three Forging blueprints, one was a regular blueprint for Three-Star Silver Quality bracers, and the other two were Gold Quality blueprints for a helmet and a weapon, each limited to three uses.

Xu Feng naturally kept the Forging blueprints to give to Zheng Yi for increasing proficiency. The equipment and Attribute Gems were split equally with Ding Xiang.

The two potion recipes were naturally kept by Ding Xiang.

This area was full of Three-Star Elite Monsters with rich drops. Originally, this should have been the harvest for a whole team, but Xu Feng and Ding Xiang joined forces and began to sweep through it.

“Big brother, a building blueprint dropped.”

Towards the end of the killing, Ding Xiang suddenly became interested in opening equipment. Every time a monster was killed and a Fate Treasure Chest appeared, she rushed to open it.

A building blueprint? Xu Feng’s eyes lit up, and a look of pleasant surprise appeared on his face.

Dropped building blueprints were much better than the upgrade buildings provided by the System, as they had some special effects that ordinary buildings did not have.

“Name: Building Blueprint Iron Fence (Upgradable) Attribute: Build an Iron Fence at the entrance and exit of the Camp passage. It can be upgraded along with the Camp. Iron Fence: Defense, 300, Health Points, 20,000. It can be attached to the castle gate or built separately at any passage entrance.”

After reading the blueprint’s attributes, Xu Feng felt happy. Before long, the Thunder Martial Hall would attack the Village of Sacrifice. If this fence was placed at the passage entrance under Sweetwater Lake, it would surely give them a surprise.

A sly smile appeared on Xu Feng’s face as he put away the blueprint.

Continuing deeper, Xu Feng found that this place was much larger than he had imagined. Based on the area of the Ancient Castle, they should have already left it by now. Clearly, they were trapped in a Demiplane.

Three hours later, the two discovered a Temple building not far away, covering a very large area. Outside the Temple were thick stone pillars, standing tall. The surfaces of the pillars were carved with complex symbols, exactly the same as the undead language behind the Horse Talisman.

Outside the Temple were layers of steps leading to the Temple gate. Outside the gate were two statues of Death Knights, each over three meters tall.

Xu Feng stepped forward and arrived at the Temple gate. The gate was slightly ajar, and the sound of metal clashing could faintly be heard from inside.

Xu Feng peeked inside. The Temple hall was empty, with only an Altar in the center. At the high point of the Altar was a huge black multi-faceted crystal, over a meter wide and three meters tall, continuously emitting thin strands of black aura.

Xu Feng threw an Insight Skill at the Altar. Immediately, a thin health bar appeared above the black crystal.

“Building Name: Undead Energy Altar, Attribute: Pollutes the surrounding environment into a plague land filled with death energy and provides energy for it, causing it to continuously expand. Health Points: 100,000/100,000!”

After reading it, Xu Feng was overjoyed. This was the core of the Death Fortress. As long as this building was destroyed, all the monsters in the undead land would become like trees without roots, water without a source. Once killed, they would not revive, and the death land would not continue to spread and expand outward. His mission this time would then be considered completed.

Looking at the empty Temple hall, Xu Feng vaguely felt something odd, and a sense of danger arose in his heart.

“Ding Xiang, control your pet to attack that Altar!” Xu Feng said in a low voice.

Ding Xiang nodded and controlled one of the half-health Skeletal Knights to charge towards the Altar.

Clip-clop, clip-clop~

The Skeletal Knight swung its blade at the Altar. Immediately, a damage number of over 300 floated up from the Altar.

Just as the Skeletal Knight was about to swing its blade for a second time, a snow-white blade light flashed from behind the Skeletal Knight.

Crack~

The Skeletal Knight, both rider and horse, was split in two and turned into a pile of broken bones.

Xu Feng’s eyes widened. Although it only had half health, it still had nearly 3,000 Health Points. Yet it was killed instantly with one slash. What exactly was that monster that suddenly appeared inside?

Xu Feng looked carefully. A Skeletal Knight clad in full armor was slowly sheathing its blade.

This Skeletal Knight only revealed its form at the moment it struck; the rest of the time, it was actually invisible in a transparent state.

Xu Feng narrowed his eyes and felt a tightness in his heart. This wasn’t a Skeletal Knight; this was a Death Knight.

Then, Xu Feng threw an Insight Skill at it.

“Name: Death Knight (Shadow), Shadow Creature, Three-Star Lord, Health Points, 11,000/11,000, Special Effect 1: Shadow Body, Special Effect 2: Lethal Strike!”

Three-Star Lord, another Three-Star Lord monster. Xu Feng was startled. Moreover, it seemed this monster was guarding the Altar. Whoever attacked the Altar, it would attack them.

Xu Feng stared at the black crystal Altar, hesitated for a moment, then a smile appeared at the corner of his mouth.

“Ding Xiang, first go capture another Skeletal Knight for yourself,” Xu Feng said.

The two turned and left. After a short while, two tall Skeletal Knights, along with Xu Feng and Ding Xiang, appeared at the Temple entrance.

“Later, do it like this…” Xu Feng whispered in Ding Xiang’s ear. Ding Xiang’s eyes lit up, and she nodded repeatedly.

“Alright, that’s the plan. You step back a bit first,” Xu Feng said.
