If Shen Sui remembered correctly, Wu Tong's deck was a very classic sci-fi deck, capable of summoning powerful high-star followers through various low-star followers.

Once the deck was actually played out, it gave Shen Sui a familiar feeling.

Shen Sui, seeing Wu Tong summoning various follower components on his field like pieces of an engine, finally couldn't hold back and asked, "Why does this follower that looks like an engine seem so familiar?"

"Have you also researched mecha followers?" Wu Tong, as if meeting a kindred spirit, detailed the power core he summoned, "This is the third-generation small-scale light nuclear fusion power core, CKPT009. I spent a lot of effort to buy it from a second-hand parts dealer."

"Ah? A power core assembly can become a follower?" Shen Sui was a bit puzzled.

"It certainly can." Wu Tong said proudly, "Besides serving as a power core to provide energy to the mecha, it can also serve as a small hydrogen bomb robot for harmless processing of target groups, and naturally can be seen as a combat unit. This was a concept proposed by a certain gentleman back in the day, and the entire mecha assembly theory in Mechanical World No. 31 is his masterpiece."

"Uh... what a violent idea." Shen Sui looked at the parts-like followers on Wu Tong's field. Undoubtedly, each one of them could be seen as a separate robot with individual combat capabilities.

This meant that when controlling mecha combat, you could even voluntarily reduce yourself to a mere stump and control limb robots to strike targets.

Indeed, the mecha combat in the worldview of World No. 31 was just this kind of style.

You must never underestimate any part the opponent throws out, as they can suddenly turn into lethal weapons, dealing great damage to you.

This concept felt somewhat familiar.

This is what Shen Sui actually cared about.

He remembered that when he played an open-world mecha free assembly 3A game before, he used this kind of strategy: first create some small specialized alien mechas, then assemble different parts to form a giant mecha.

Although you need to multitask in controlling several mechas, once you managed this, you could deliver curtain-like blows to your opponent.

The crucial thing is that this game's mecha system was derived from some EVE, meaning if it exploded, it would be truly irreversible, so this method also minimized losses. When faced with enemy encirclement or when defeat was inevitable, you could just shed an arm like a lizard's tail and engage in combat while escaping hastily.

"Pay 8 Soul Points, activate from my hand, Spell Card [Assembly]!" Wu Tong activated the pivotal card of his deck from his hand, and after summoning all the parts, he had to assemble them to form a brand new mecha follower, "Stack the corresponding parts on my field! Special summon [Ice and Snow Heavy Armor: Legend III] from my deck!"

In this regard, his deck somewhat had a fusion aspect.

However, there's a little difference: the followers summoned via "fusion" and "overlay" were within the main deck.

A slight variant is that the mechas requiring assembly didn't have to be assembled to debut; once drawn, you could pay Soul Points to normally summon them to the field, but without overlay materials, such mechas acted only as blank Mortal Bones for attack points, or used their effects that didn't require overlay materials to gain overlays for summoning other mechas.

Overall, although the decks from Mechanical World No. 31 were generally slightly less powerful than the top-tier, the playability and aesthetics far exceeded many competitive decks.

Few men could resist the sight of slowly gathering parts to build a Gundam unique to themselves.

Therefore, World No. 31 is a must-choose Soul Card World for many mecha enthusiasts.

"When you activate your card effect." Shen Sui was familiar with this deck and wouldn't pamper Wu Tong's problem, "Activate the effect of Follower Card [Elemental Life: Lava Fairy] from my hand."

Shen Sui directly activated a hand trap card to counter Wu Tong's [Assembly].

But this didn't stump Wu Tong; surely he wouldn't depend only on such a card to pile up a Gundam to defeat the opponent?

Indeed, after the failure of [Assembly], Wu Tong took another approach, directly activating CKPT009 power core's effect.

"Activate CKPT009 power core's effect, stack my field's [Left-Hand Specialized Weapon Assembly·RI01], [Right-Hand AK001-type Laser Cannon], [Universal Four-Legged Mecha A-041], and [Universal Trunk Specialized Mecha HGF321]!"

Then, Wu Tong specially summoned a snow-white mecha from his deck.

He activated the mecha's effect, released it, summoned all stacked materials to the field, and summoned a [Heavy Armor] follower from the deck.

Wu Tong opened his deck, and a golden light shot toward the sky.

Seeing Wu Tong's summoning, the ninth-tier Life Card Master who recommended him showed an appreciative look, even a hint of envy, "It's here, one of the legendary mechas in our World No. 31!"

Wu Tong swung his hand grandly and proudly declared, "Special summon from my deck! [Legendary Heavy Armor: Ninth Sacrificial Demon]!"

"Ancient heavy armor, descend again!"

"In this realm, rewrite the invincible legend!"

"Special summon!"

"Ninth Sacrificial Demon!"

A plain black mecha landed steadily on Wu Tong's field with a loud crash.

Shen Sui saw the mecha before him and was slightly stunned.

D*mn, why does this look so familiar?

Shen Sui rubbed his eyes and took another look.

An absurd thought appeared in his mind.

The extraordinary power let him recall vivid details from deep memory upon seeing a recallable anchor point.

If my memory serves me right...

The heavy armor mecha that Wu Tong proudly summoned might, perhaps, possibly, probably, is...the experimental machine I cobbled together back then, and a failed model too, seemingly sent as cannon fodder to attract enemy attention during some major battle, only to crash onto some inconspicuous planet.

Since it's not a very important mecha, Shen Sui basically treats it as junk, not even bothering to recycle it...

"Awesome, right? This is a master's mecha!" Wu Tong saw Shen Sui looking at the Ninth Sacrificial Demon in silence and thought he was stunned, saying proudly, "I was very lucky to dig it out from an asteroid! It's the work of the legendary Master of Sacrificial Demon. According to the Sacrificial Demon Research Association's data, this mecha is numbered 009, it's Master of Sacrificial Demon's ninth work, also known as the Ninth Sacrificial Demon."

Sh*t!

Just hearing this name made Shen Sui feel even more familiar.

Because his nickname in that game was Guardian of Pure Love: Sacrificial Demon.

Shen Sui wiped the cold sweat off his forehead.

Due to the high degree of freedom in this mecha assembly game, Shen Sui has many abstract works in it.

For example, the replica game card Celestial Thunder and Electronic Dragon, Cat Girl Gundam, Maid Gundam, and various abstract yet accurate Painful Gundams, including the Hatsune Miku paint job...

This Ninth Sacrificial Demon before him was still one of his early works.

Suddenly, Shen Sui had the urge to quickly visit Mechanical World No. 31 to hide all his black history.

Looking at this black history, Shen Sui instantly lost interest in watching the opposite side stack Gundams. He ended it quickly; viewing it one more time was disrespecting himself.

Then, he activated his hand card [Deep Sea Fish King: Cleveland].

"???"

Wu Tong watched his recent proud summon turn into a fish and fell silent.

"This card of yours..." He had seen Shen Sui duel with Zhou Keji. "Is it glued to your hand? Two consecutive starts with it? Is there really only one Deep Sea Fish King in your deck?"

In the Life Card Duel, the follower cards are limited to one.

Shen Sui drew it at the start of two consecutive duels, which did somewhat break Wu Tong's defense.

"Haha, maybe it's the new card version's bonus." Shen Sui was also a little embarrassed; the opponent had painstakingly stacked a Gundam, and he fed it to the fish in the blink of an eye, feeling apologetic.

The summoning condition of Deep Sea Fish King is that the opponent has conducted more than five summons or special summons; it doesn't require five followers on their field, and Wu Tong had already met this condition. Shen Sui didn't activate it earlier because he wanted to see if there was any cooler Gundam later.

In the end, he didn't see anything cooler but bumped into his black history.

Only then, Shen Sui couldn't hold back and activated it hastily.

"I bet even that Holy Artifact Puppet is glued to your hand, right?" Wu Tong cautiously asked Shen Sui.

After all, Zhou Keji lost to Shen Sui this way.

"Oh, not really." Shen Sui scratched his head, saying.

Wu Tong breathed a sigh of relief.

Then Shen Sui discarded some cards according to the effect of the Deep Sea Fish King.

This time, he only discarded two cards, summoning a Deep Sea Fish Derivative on Wu Tong's field.

By this step, most of Wu Tong's unfolding resources were nearly exhausted.

He concealed two cards and directly ended his turn.

Shen Sui then drew a card and launched a [Thunder Strike], paying half his life value, aiming to clear Wu Tong's rear field.

Wu Tong was helpless and had to activate one of the concealed cards' effects, specially summoning a Heavy Armor follower's component onto his field.

"Activating my hand card [Fish King: Paiyiga]'s effect." Shen Sui drew the Fish King from his hand, directly liberating Wu Tong's Heavy Armor follower and [Deep Sea Fish King: Cleveland], specially summoning [Fish King: Paiyiga] on Wu Tong's field.

Wu Tong's mouth twitched.

Then he saw Shen Sui drawing another card from his hand.

"Next, I activate my hand card [Mutated Fish King Anludron]'s effect, liberating the fish king and Deep Sea Fish derivative on your field." Shen Sui liberated Wu Tong's last two followers, summoning the Mutated Fish King.

As long as the Mutated Fish King is on Wu Tong's field, he cannot conduct summoning or special summoning. He must draw two cards each turn, and crucially, the Mutated Fish King cannot make an attack declaration.

It's okay.

After glancing at the effect, Wu Tong comforted himself: at worst, liberate it.

Then Wu Tong saw Shen Sui pull out a [Vivian's Matchbox] and equipped it to the Mutated Fish King.

[Vivian's Matchbox], the equipped follower cannot be liberated....

"I surrender!"

Wu Tong surrendered decisively.

He really didn't want to end up in prison.
