Chapter 648: Arduous Challenge

"Good stuff." Xiao Feng was fairly satisfied with this reward.

Although it's a consumable, it instantly fills HP and adds a 60-second efficient recovery state; the value of this Divine Elixir is extremely high!

At this moment Xiao Feng is in a dangerous HP situation; if he takes it in one gulp, he can escape danger.

He is reluctant to use it…

Even if the Heavenly Tower challenge fails, it's no big deal; he can just try again next time.

To spend such a rare potion on this challenge would make him heartbroken!

Before he could think, the boss of floor 703 spawned.

This boss is different from the previous ones; it's a Celestial God Clan boss.

The so-called Celestial God Clan are a group of high-level life forms born from cosmic creation, without fixed biological forms.

Some resemble humans, some resemble rocks, some resemble insects; their appearance can be described as a mishmash of all races, having everything.

In the real universe, they are extraordinarily powerful, born transcendent, and as adults each one is extremely domineering.

However, their population is tiny, less than one-billionth of other civilizations.

Therefore, Celestial God Clan players or NPCs in the game are relatively rare.

The floor 703 boss is a "spiritual aura" type boss, with no fixed form, just a mass of cyan-green airflow.

Its strength is an incremental level above the previous two bosses; it is completely immune to physical damage and can only be attacked with pure-energy skills.

Xiao Feng's Source Attribute Skill happens to be usable, making the fight not too difficult.

This boss lacks strong burst power; after a fierce battle lasting one minute, Xiao Feng easily won.

After clearing one floor, floor 704 quickly began.

Xiao Feng fought with all his might against the Supreme God-level boss, hoping to clear a few more floors.

This challenge does not limit the use of Divine Elixirs and scrolls; to fight faster, he also used attribute-boosting Divine Elixirs, his output became outrageous, Source Needles fired at high frequency, and he could kill a boss in about 30-40 seconds.

These bosses are each more ferocious than the last; if he couldn't kill them quickly, he would be the one to die.

Floor 704, 705, 706…

The battle pace was extremely fast; Xiao Feng focused intensely, daring not to be the slightest bit careless.

The monsters here are too strong; with Secret Art in hand, any slight negligence could lead to him being instantly killed, ending the challenge.

Relying on his outrageously high output, Xiao Feng managed to reach floor 710 without dying; instead, he gradually used recovery elixirs to refill his HP bar.

Starting from floor 711, the difficulty became increasingly high.

Xiao Feng summoned the Flame Monarch to assist in battle,

When he couldn't dodge, he would hide inside the Flame Monarch's palm, just like when he dealt with the female war god, using a shameless tactic to hide and output.

The Flame Monarch's HP is absurdly high, already exceeding 1,900 trillion; even a Supreme God would find it hard to kill it.

Relying on this big guy's help, Xiao Feng endured another 10 floors of difficulty, climbing to floor 721.

At the start of floor 722, the boss's level had risen to 574, its HP to 33.4 billion, making it ever harder to defeat.

Xiao Feng gritted his teeth and endured, relying on his own attributes and Divine Elixir support, stubbornly surviving another three floors to reach floor 725.

At this point his floor count still lagged 31 floors behind "Ultra-Dimensional Mech Soldier No. 17", and Xiao Feng did not want to end here.

Even if he were to lose, he would lose only to that human who is in first place!

The floor 725 boss appeared before him, a Supreme God of the Giant Beast Clan, resembling a fox but far more ferocious.

As soon as it appeared, Xiao Feng was knocked flying by its agile moves, taking several hits in a row, his HP plummeting by over 13 billion.

Unwilling to end like that, Xiao Feng raised his Source Attribute Shield to block, unleashed the first-tier Secret Art 【Palm Heaven and Earth】, and instantly killed the Fox Supreme God with full HP.

【Congratulations on clearing floor 0725 challenge!】

【You earned 725 challenge points!】

【You obtained 1 Tier 4 Divine Elixir!】

The system rewards were issued again, giving him another bottle of Divine Elixir.

Xiao Feng opened his backpack and glanced at its effect.

【Illusory Holy Elixir】: Tier 4 Divine Elixir, makes the user become illusory, immune to all physical damage below level 999, and grants a teleport ability every 3 seconds, lasting 60 seconds.

This potion made Xiao Feng delighted.

The floor 726 boss spawned immediately, and it happened to be a physical-type boss!

He hesitated not, directly consumed the Illusory Holy Elixir, his body entering a half-virtual, half-real state, then stood in place and relentlessly attacked the boss!

In the situation where he didn't need to dodge skills, his output capacity increased severalfold.

Every 2 seconds he threw 12 Source Needles, every 3 seconds a Source Burst Technique, plus some magical skills…

In just 10 seconds, the boss was instantly killed!

Next came floor 727, another physical-type boss.

Xiao Feng still stood and attacked, taking advantage of the potion's effect not yet ended, he went berserk with output; with the boss looking dazed, he directly took it down!

"Quick, quick, quick, bring on a few more floors!"

Each floor challenge includes a 10-second rest time, making Xiao Feng quite annoyed, feeling that he's wasting the potion's buff duration.

The floor 728 boss appeared, a magic-type boss.

Xiao Feng teleported to dodge skills while wildly outputting.

13 seconds later, the boss died again.

At the same time, the potion had only 7 seconds left, unable to last until the floor 729 battle.

However, at this moment…

【Congratulations on clearing floor 0728 challenge!】

【You earned 728 challenge points!】

You obtained 1 portion of Tier 4 Divine Medicine!

Another potion appeared in the backpack.

Xiao Feng opened it and instantly beamed with joy.

【Wind Phantom Potion】: Movement speed increased by 200%, lasting 300 seconds

This potion can make his already considerable swift speed even more exaggerated, making dodging skills much easier.

And the duration is also very long!

The boss on floor 729 appeared, a human swordsman, looking quite formidable.

Xiao Feng immediately consumed the Wind Phantom Potion, maxed out his speed, then began a kiting tactic, leading the boss around while outputting with Source Needle and Source Burst Technique.

In less than 20 seconds, the human swordsman chief god fell with resentment.

After resting for 10 seconds, the challenge on floor 730 began.

Xiao Feng repeated his old trick, taking advantage of his strong speed state to kite and kill the chief god bosses one after another.

In the blink of an eye, floor 737 arrived.

The effect of the Wind Phantom Potion disappeared, and Xiao Feng's pressure increased again.

He took a batch of ordinary state potions, fought the floor 737 boss, and simultaneously his divine artifact hat shattered, forcing him to replace it with another superior divine artifact.

He seized the moment to gulp down some blood, and when the floor 738 boss appeared, he decisively took out a scroll and tore it open on the spot!

【Chief God's Blessing Scroll】: Tier 4 scroll, all attributes increased by 500% within 20 seconds, usable only below level 500

After the scroll took effect, his health cap surged to over 320 billion, and his attack and defense attributes became extremely monstrous.

Under this terrifying fivefold attack, the boss was killed in just five seconds.

There were still 15 seconds of buff left, of which 10 seconds were used to cooldown the challenge.

When the floor 739 boss appeared, the state still had 4.5 seconds remaining.

Xiao Feng seized the time to frenetically output, using this 4.5-second attribute explosion to kill another boss.

"Just one more layer, just one more layer and we'll be fine!" Xiao Feng thought.

As long as he defeats the floor 740 boss and then uses the "skip 10 layers" privilege, he can pass this major stage and obtain a stage reward.

Then, it's time to chase the achievement of "Ultra-Dimensional Mech Soldier No. 17"!
