Units flew out from the three battleships, spreading to every direction of Thousand Feather City, each formation having a thousand people, totaling one hundred and fifty formations for fifteen thousand people.

Each formation contained a standard array of 108 people, mostly comprised of the All Heaven Fiery Array or the Celestial One Profound Ice Array.

These arrays were not useful during a siege, primarily serving to allow players in the array to take cover when the enemy concentrated their fire, holding out until support from other formations arrived.

Once encirclement was formed, Gu Zhiqiu gave the order, and all one hundred fifty thousand subordinates acted simultaneously, unleashing flying sword treasures or magic to bombard the City Defense Barrier relentlessly.

With many subordinates supplementing the output, the restoration speed of the City Defense Barrier was significantly delayed. When forty thousand Divine Thunder Towers from the three battleships concentrated fire again, the defense of the City Defense Array dramatically declined once more.

If repeated continuously, it became apparent in just three rounds that the restoration capability of the City Defense Array could not match the output.

Every round of offense and defense resulted in a loss of six to seven million defense points.

Ten rounds resulted in a loss of sixty to seventy million defense points.

The City Defense Array’s total defense was nine hundred million, and in just over ten minutes, its defense had been cut in half.

Once the defense cut down to a certain figure, Gu Zhiqiu immediately ordered in the guild channel for the Divine Thunder Towers to align more closely with the main cannon.

Fifteen seconds later, the Heaven’s Wrath main cannon fired simultaneously with six Celestial Strike main cannons and forty thousand Divine Thunder Towers, and the explosion exceeding three hundred million instantly broke through the remaining defense of the City Defense Array, tearing it open on the spot, and the remaining thunder fire blasted into the city, killing a swath of enemies instantly.

"Attack!"

The one hundred fifty formations scattered, summoning countless Gu insects, forming a vast Gu cloud to fill the gaps between formations, intercepting Celestial God Association players escaping from the city.

Among these dense Gu insects were numerous large Gu creatures above level one hundred. These large Gu creatures were thick-skinned, with HP no less than beast-type bosses, blocking in front by the hundreds, shielding ordinary Gu creatures from wide-area magical blasts.

These large Gu creatures above level one hundred were refined from the Gu Abyss.

Ten Thousand Poison Island had three large Gu Abysses, seven medium Gu Abysses, and sixteen small Gu Abysses, capable of consistently refining large Gu creatures over level one hundred, now numbering around six to seven thousand.

The Thousand Star Hall monopolized Ten Thousand Poison Island, with the finest toxic Gu resources in their control.

Even though the Gu Dao Stream struggled in the later stages, with difficulty in establishing Dao Foundation, and even those who luckily survived their tribulation typically only have low-grade Dao Foundations with mid-grade being rare and top-grade nearly unseen for millennia, making them quite weak among Loose Immortals, it is a T1 strong stream at the Qi Refining stage.

Thousands upon thousands of Gu insects surged forward, and ordinary cultivators found it hard to withstand without powerful Dao techniques and treasures.

Large-scale group battles were also formidable, as now more than one-third of these fifteen thousand people practiced the Gu Dao Stream, producing forty to fifty million Gu insects within minutes, with the carefully refined Gu insects having high levels, hundreds of large Gu creatures over level one hundred coalescing into a Gu cloud spanning over hundreds of kilometers, drowning the entire city after the city’s fall.

The enemy’s resistance was also fierce, with some expert’s powerful forbidden techniques unable to be blocked even by hundred-level Gu insects, incinerating hundreds of acres of Gu insects with a single strike, causing severe losses to ordinary Gu insects.

Yet Ten Thousand Poison Island had nothing but loads of Gu insects.

One batch died, another was released to fill in, consistently maintaining Gu insects to suppress Celestial God Association.

"As the saying goes, Gu Dao Stream is indeed very powerful at the Qi Refining stage."

Through the water mirror, Su Yu overlooked the entire battlefield, speaking to the senior guild officials behind him:

"We can build more Gu farms, refine more Gu insects for backup, and I recall half of the guild’s Gu Abyss is leased out, correct?"

Gu Zhiqiu immediately answered:

"Yes, the guild has a total of three large Gu Abysses, seven medium Gu Abysses, sixteen small Gu Abysses, with one large Gu Abyss, three medium Gu Abysses, and eight small Gu Abysses rented out, additionally, we sell a batch of Gu insects every year to gain income."

"No need to sell them in the future; keep them all for guild members to exchange."

"Furthermore, aren’t there many Gu insects available on the market? Buy all rare Gu we can find; it shouldn’t cost much, right?"

"It doesn’t cost much, at most costing forty to fifty thousand a month to acquire most of them."

"We’ll do that then, forty-five hundred thousand gold annually in this area."

Su Yu made the decision.

The guild hasn’t been established long and doesn’t have as much accumulation as other veteran Overlord Guilds, to bridge the gap, we’ll need to be willing to spend money.

While they chatted idly, the guild had already completed the total suppression of the Celestial God Association, firmly containing them in the inner city area resisting stubbornly.

But such resistance was futile, as the two Celestial Strike Battleships slowly descended to join the fight, the resistance within the city quickly dissolved forcibly, six Loose Immortals and over a hundred Celestial God Association mid-to-high-level personnel broke through forcefully, unleashing a barrage of thousands of thunders, a single shot from the Heaven’s Wrath main cannon pierced through the crowd, wiping out most instantly.

The remaining scattered and fled, with three Loose Immortals among them, one being the Celestial God Association’s Vice President Jiang Lang, who narrowly escaped, casting a vengeful glance at the airships above, only to see a dark axe blade appear out of nowhere before his face.

Before he could react, his Protective Treasure was torn apart, and the axe blade swept across, cleaving him in two.

Sitting on the battleship, Su Yu’s heart stirred upon witnessing this scene, stepping forward and disappearing instantly.

In the next second, appearing outside the Heaven’s Wrath Battleship, revealing his true form and wielding the Sky Splitting Divine Axe to chop down, the axe blade cutting no more than thirty feet before vanishing into thin air.

Seeing this scene, Gu Zhiqiu and others who followed out were bewildered, asking curiously:

"Boss, what’s this?"

Su Yu, with a flick of his hand, stowed away the Sky Splitting Divine Axe, chuckling:

"Try a Divine Technique."

After speaking, an insight emerged in his heart, and he closed his eyes, entering a peculiar state.

A faint wave appeared out of thin air, surrounding him. Gu Zhiqiu observed this scene and spoke with a heavy tone:

"Everyone, do not get close to the President."

It was truly mystical; Su Yu couldn’t distinguish front from back at the moment, but in the depths of his being, he knew he must swing this axe.

If he didn’t swing this axe now, Jiang Lang would still die, but the one taking action would not be himself, but his future self.

Manipulating Time: a Divine Technique of the Law of Time, allowing one to strike the target 60 seconds in the past or future along the timeline. Mana cost is 100,000, cool down time of 10 days.

When Jiang Lang dies from an inexplicably appearing axe force, it means that he used this time divine technique to kill Jiang Lang within 60 seconds after his death.

But it doesn’t mean he has to act; he can choose not to act.

However, Jiang Lang has already died in the past, the effect is established, there must be a cause.

Normally, he is the cause, but if he does not act now, cause and effect will become chaotic, time and space will be disordered, and he must fill this cause.

If his current self does not act, only his future self can act to fill this cause.

Su Yu cannot be sure if his future self has this ability, but he is sure that to become immortal, he must resolve cause and effect. If he does not act, his future self, who is about to undergo the Celestial Human Tribulation, will need to act to fill this cause.

An insight emerged in the depths of his being, which will greatly impact his future self’s crossing of the Celestial Human Tribulation.

Therefore, he must act to fill the cause of Jiang Lang’s death.

When he comprehended the cause and effect, the power of Time Sword surrounding Su Yu began to shrink inward, merging into his body.

"Hint: You have gained insight during enlightenment, Law of Time +4, comprehended Divine Technique ’Step into Time’!"

Su Yu slowly opened his eyes, showing joy on his face.

"It’s actually enlightenment!"

He had heard of this; after Foundation Establishment, there is a chance to enter a state of enlightenment in daily life, thereby boosting strength or gaining benefits out of thin air.

For example, suddenly upgrading the grade of Dao Foundation, from lower-grade Dao Foundation to mid-grade Dao Foundation.

Suddenly comprehending a Dao technique or forbidden divine technique.

Or with a very small probability, suddenly comprehending Mastering Law. If already mastered, the degree of law mastery will increase greatly.

This reminded Su Yu of the time when he was completing the mission for the Xuankong Mountain sect inheritance, seeing many aged Loose Immortals closing themselves off underground at the Blood Evil Sect. Their main goal was to have one enlightenment to improve the grade of the Dao Foundation.

Such aged Loose Immortals mostly have lower-grade Dao Foundations, constrained by their foundation’s level, unable to upgrade further.

If unambitious, they can still live well.

With the cultivation of Loose Immortals, many young and attractive female newcomers are willing to follow.

But if still unsatisfied, they will push for closure, attempting to gain enlightenment during closure to improve their Dao Foundation grade, thereby continuing cultivation.

In the other world, lower-grade Dao Foundation faces a bottleneck at level 120 when upgrading to level 130; the experience and Dao proficiency required are directly doubled, increased by 100%.

Upgrading from level 130 to level 140 doubles again, experience and Dao proficiency needed +200%.

Upgrading from level 140 to level 150 doubles again on the previous tier, experience and Dao proficiency needed +400%, and so on, continuously doubling. At level 190, the upgrade requirement is 12,800%, extremely exaggerated.

Mid-grade Dao Foundation is slightly better, facing a bottleneck at level 150 to 160, also starting from 100%, reaching 1,600% by level 190. Although extremely high demand, there’s at least that chance.

Lower-grade Dao Foundation basically can’t upgrade past level 150; after that, they have to either mess around or close off and gain enlightenment to improve Dao Foundation grade.

As long as they manage to improve to mid-grade Dao Foundation, there’s a chance to go further.

As for upper-grade Dao Foundation, even with just three grades, there’s no such issue. Upper-grade Dao Foundation doesn’t face bottlenecks at the Loose Immortal stage and can smoothly upgrade to level 200 in preparation for tribulation.

This is the difference of Dao Foundations, grade decides life or death directly.

Fortunately, Su Yu doesn’t have this issue; Super-grade Immortal Foundation ensures no bottleneck in cultivation, whether at the Earth Immortal stage or after becoming immortal.

Having gained enlightenment once, Law of Time +4, now Law of Time +10, all Sword Formulas and Divine Techniques based on the Law of Time will be enhanced accordingly.

However, it’s not like the previous linear enhancement, but a minor qualitative transformation at Law mastery +10.

Time Sword - Overdraw Future (Dao Foundation): Utilize Time power to borrow strength from the future, attack power and speed +1 million, lasts 30 seconds, mana cost 50,000, cool down time 15 days.

For each additional point of Law of Time on the existing +10, attack power +100,000, duration +5 seconds.

Time Sword - Flow of Time (Dao Foundation): Utilize Time power to cut off target’s lifespan, cut off 350 years’ lifespan at the same level, changing according to the strength difference between both parties, mana cost 50,000, cool down time 24 hours.

Based on the existing Law of Time +10, each additional point increases base lifespan cut off +25 years.
