Chapter 566: Chapter 281 Light and Dark Origin Stone! (Four in One) _2 When switching to Dark Mode, all your skill power decreases by 50%, and cooldown times decrease by 50% (this cannot affect skills immune to cooldown reduction but can stack with other cooldown reduction effects). (Can be activated from the inventory). When switching to the Light-Dark Fusion Mode, all your skill power increases by 100%, and cooldown times decrease by 50% (this cannot affect skills immune to cooldown reduction but can stack with other cooldown reduction effects). (Can be activated from the inventory). [Item Introduction]: The Light and Dark Origin Stone is a mythical-grade gemstone, containing powerful light and Dark Energy. Using this gemstone allows the holder to switch between light and dark power forms at any time to adapt to different combat needs. After examining the Light and Dark Origin Stone, Chen Mo felt it was quite useful. Although he already possessed Extreme Calmness, a 90% cooldown reduction skill, normal cooldown reduction effects could not stack. However, the Dark Mode of the Light and Dark Origin Stone explicitly stated that its cooldown reduction effect could be stacked. On this point alone, this Light and Dark Origin Stone had a very high value. For some skills with long cooldown times, a mere 90% cooldown reduction was not enough. Besides affecting skill cooldown times, the Light and Dark Origin Stone also brought a significant enhancement to skill power. The Form of Light increased skill power but required longer cooldown times. However, sometimes, extending the cooldown time did not necessarily have a significant impact. For example, Chen Mo could now activate the Form of Light to use powerful skills, such as summoning and shields, all of which would achieve greater effects. This was different from waiting for a skill to cool down before casting. The Form of Light directly increased skill strength by 100%, and this enhancement effect could break the original limits. Additionally, there was a unique Light-Dark Fusion Mode. Once this mode was entered, it was purely beneficial, combining the two forces, enhancing skill power and shortening cooldown times. This Light and Dark Origin Stone could definitely bring a powerful combat advantage to the holder, allowing them to apply it flexibly according to different situations. 𝐟𝕣𝕖𝐞𝐰𝕖𝚋𝐧𝗼𝚟𝐞𝕝.𝗰𝐨𝐦 Chen Mo was pretty satisfied with this harvest. Having obtained it, Chen Mo naturally couldn’t resist trying it out. As he entered the Form of Light, Chen Mo saw that many of his active skill effects had changed accordingly. The shield was thicker, the attack power boost from the Worship Skill was higher, and the Healing Wave’s damage also increased. Apart from the longer cooldown times, there were absolutely no other drawbacks. Chen Mo directly used the shield and Undying Worship Skills on the nearby Skeleton Monster. This caused the shield, which originally had a value of over two hundred million, to instantly reach five to six hundred million. Other than that, the Worship Skill also boosted the Skeleton Monster’s attack power and attack speed to triple their original values. The enhancement effect was quite significant. Although the cooldown times had lengthened, they hadn’t increased by a great extent. After all, the Form of Light clearly stated that only the added part of the cooldown time was not affected by cooldown reduction, meaning the original part was still influenced by cooldown reduction. The cooldown time of the shield skill was 30 seconds. According to Chen Mo’s Extreme Calmness effect, the cooldown was reduced to only 3 seconds. Even after adding an extra 30 seconds of cooldown time, it was still only 33 seconds. There was not much impact at all. It might not be useful in actual combat, but enhancing the initial casting had absolutely no problems. After all, this type of shield was permanent. It would not be dispelled unless the caster and the target affected by the skill were no longer in the same space. Similarly, the Worship Skill was now also permanent. Although its cooldown time was longer than the shield’s, at 60 seconds, he only had to wait 66 seconds to use it again. It could hardly be considered a long time. Chen Mo only had to wait a short while on the 24th level, and his skills had already cooled down. At this time, he set foot on the stairs to the twenty-fifth floor with his Skeleton Army, which was now even stronger than before. The next five levels—25, 26, 27, 28, and 29—did not feature any hidden missions. After Chen Mo easily passed through them, he obtained 5, 6, 7, 8, and 9 points of Divine Power, respectively. He had now obtained a total of 45 points of Divine Power. Finally, Chen Mo arrived at the 30th floor. [The Heavenly Path’s Hint: The trial of the 30th floor of the Trial Tower officially begins. The trial of the 30th floor is an Ultimate Challenge. You will face an Ultimate Challenge. This is a Spirit Collective Body of all challengers who failed in the Trial Tower. This Spirit Collective Body will possess all the abilities of these failed challengers. However, its Divine Power will be limited to the same as yours and will ignore your hidden divine power. You must eliminate the Spirit Collective Body of the failed challengers within the specified time. Please do your best to defeat it!] Upon hearing The Heavenly Path’s Hint, Chen Mo was shocked and incredulous about this Ultimate Challenge. "A Spirit Collective Body of all failed challengers? Doesn’t that mean it will possess the abilities and experience of countless geniuses? That combat power is simply absurd!" Chen Mo murmured. While he was still complaining, an extremely terrifying energy fluctuation suddenly erupted from the central area of the thirtieth floor. With the appearance of this energy fluctuation, the ground immediately began to tremble, the surrounding air seemed to solidify, and an oppressive feeling filled the entire area. As the energy fluctuations condensed, a huge shadow gradually appeared.
