With skills that can be upgraded infinitely, if I'm invincible, who is?

A moment later, the corpse of the Bloodthirsty Beast King turned into bloody light and dissipated, and a blood crystal half the height of a person appeared in Su Yu's sight.

Swish!

The next instant, the blood crystal disappeared from its original spot and was put into the backpack by the Qiankun Ring.

Su Yu opened his backpack and examined the blood crystal he had just acquired.

[Level 60 Epic Super Blood Crystal (Special Item): Go to the Crimson Altar to convert Blood Crystals into Trial Points. One Level 60 Epic Super Blood Crystal can be converted into 640 million points.]

"That's interesting. One level 60 epic super blood crystal is at least equivalent to 11 level 60 epic blood crystals." Su Yu nodded slightly.

However, he soon discovered something even more interesting.

His Blood God Treasure points increased by 800.

If the previous pattern holds true, this is equivalent to killing 100 Star-level Bloodthirsty Beast Commanders.

The 640 million Crimson Trial points are also equivalent to 100 level 60 Star Blood Crystals.

In other words, the Bloodthirsty Beast King he just killed was essentially an aggregate of 100 Star-level Bloodthirsty Beasts.

However, it is clear that the former is several levels more difficult than the latter.

Su Yu even suspected that without the boost of true damage, his basic attacks and phantom combos would be unable to break through the Bloodthirsty Beast King's defenses.

Furthermore, the combined attack of 100 Star-level Bloodthirsty Beasts might not even be able to break through Su Yu's shield.

However, the Bloodthirsty Beast King's attacks contain true damage, which can pose a considerable threat to Su Yu.

Clearly, starting from wave 251, the Blood God's Treasure places greater emphasis on testing the professional's maximum output and maximum survivability.

A short while later, the 252nd wave of monsters spawned, and it was once again a bloodthirsty beast king that was tens of meters tall.

[Level 60 Bloodthirsty Beast King (Epic Boss)]

[HP: 7100 million/7100 million]

"No problem, it only increased my health by 100 billion." Su Yu breathed a sigh of relief.

With his current output capabilities, he can deal hundreds of billions of damage in less than two seconds.

"Let's play with it slowly this time, and trigger its third phase after the next wave of monsters spawns," Su Yu thought to himself.

Having learned from his previous experience, he naturally wouldn't allow himself to fall into that same passive situation again.

As long as you stall until the next Bloodthirsty Beast King spawns, you'll be safe once you have a health pack to drain its life.

At this point, he would have no problem facing dozens of third-stage Bloodthirsty Beast Kings at the same time.

Su Yu controlled his attack rhythm, and the Bloodthirsty Beast King's health was slowly decreasing at a rate of about 0.25% per second.

Five minutes later, the 253rd wave of monsters spawned, consisting of a Bloodthirsty Beast King with a staggering 7200 billion HP.

Seeing this, Su Yu went all out and soon unleashed the third stage of the previous Bloodthirsty Beast King.

He then turned his attention to the Bloodthirsty Beast King that had just spawned.

Wave 254.

Wave 255.

……

And so, one after another, the kings of bloodthirsty beasts died at Su Yu's hands.

Finally, a system notification sounded in Su Yu's ear.

The first stage of the Shadow Archer class advancement quest (the only quest at the God-tier level) has been completed. Please open the quest panel to claim your reward.

"Finally, the first phase of the mission is complete." Su Yu's eyes were practically overflowing with joy.

Completing this task not only means he can immediately obtain the Shadow Archer's exclusive weapon, but also means he is one step closer to advancing the Shadow Archer to god-like status.

With a thought, Su Yu opened the task panel and directly claimed the task reward.

[Congratulations on obtaining the Shadow Archer's exclusive weapon: Shadowfang!]

The second stage of the Shadow Archer class advancement quest (the only quest at the God-tier level) has been released. You can view details in the quest panel.

Without any hesitation, Su Yu immediately opened his backpack and checked the attributes of Shadow Fang.

Shadowfang (Epic)

[Level: 1]

[Attributes: Critical Hit Rate +30%, Critical Hit Damage +30%, Final Attack +20%, Final Damage Amplification +20%.]

Feature 1: After defeating a BOSS with an equipment level and grade no lower than the equipment level and grade, you can obtain growth points. Once the growth points meet the requirements, you can upgrade the equipment level and grade.

Note: The highest level that equipment can currently be upgraded to is its own level, and the highest tier is God-tier.

[Feature 2: Shadowfang can freely switch between bow and dagger forms with no cooldown.]

Feature 3: Legendary unlock.

【characteristic……】

[Equipment Requirements: Shadow Archer, soul-bound to Emperor Yu.]

Su Yu switched to Shadow Fang with a satisfied expression, tried out the form-switching function, and then switched it back to bow and arrow form.

Currently, he is most comfortable using the bow and arrow form, and most of his attack skills can only be used in the bow and arrow form.

Currently, his only attack skills are Soul Severing Arrow, Lightning Arrow, and Phantom Combo.

Of these three skills, only Phantom Combo, a class-specific skill, is not restricted by weapon type.

As for the skills Thunder Emperor's Wings and Eternal Night Stealth, although they also have offensive functions, they are essentially support skills.

"Now my regular damage output has increased by at least 40% to 50%." Su Yu looked at the damage he had dealt and nodded in satisfaction.

Shadowfang provides four percentage-based attributes: critical strike chance, critical strike damage, final attack, and final damage amplification.

The latter two are new attributes for Su Yu.

Under normal circumstances, Su Yu does not receive any final damage amplification bonus.

This 20% increase in final damage alone can directly boost Su Yu's output by 20%.

In addition, the 20% final attack is also an independent multiplier, and these two new attributes can increase Su Yu's output capability by 44%.

The additional 30% critical strike damage may not seem like much, but it's still a few points of improvement.

All things considered, Shadow Fang significantly improved Su Yu's abilities.

Now, Su Yu's Soul-Severing Arrow, which consumes a thousand times the mana, can deal approximately 13.1 billion damage.

That translates to a staggering 86.6 billion damage per second!

Even with all its firepower unleashed, the Bloodthirsty Beast King couldn't last even two minutes against Su Yu.

And that still includes its 20-second invincibility period.

After checking Shadowfang's attributes, Su Yu decisively opened the quest panel, and a brand new quest appeared in his sight.

[Shadow Archer Class Advancement Quest (Unique, God-Tier Quest)]

[Second Stage Mission Requirements: Defeat 20 Legendary Bosses, with each boss being at least level 100.]

[Task Time: Unlimited.]

[Mission Reward: Shadow Archer Exclusive Armor Set (with the potential to be upgraded to God-tier equipment), and unlocks the third stage of the mission.]

[Mission Penalty: None.]

[Note: After completing all stages of the mission, the Shadow Archer's rank will advance from God-tier to Super God-tier.]

"Kill 20 legendary bosses of level 100 or higher?" Su Yu pondered.

The second phase of the mission is the same as the first phase, except that the requirements are a level higher.

The difficulty of the mission remains finding the monsters!

Finding 20 legendary bosses of level 100 or higher is definitely not an easy task.

At least in the short term, Su Yu has no clue what to do and can only take it one step at a time.
