Digimon: I reached the top using the Knight item.

"It's not entirely for your sake; I've also had conflicts with the Steel Empire in the past."

Bai Yu hadn't thought about the Steel Empire for a long time.

Speaking of which, tens of thousands of years ago, he also had a friendly cooperative relationship with the Steel Empire.

But that's in a parallel world.

In this main world, he and the Steel Empire are only in conflict.

Shiraha decided not to leave yet, but he still had to send Nishijima Daigo back.

Firstly, it was no longer his business, and secondly, once he returned, he could explain the situation to Mitsuo Yamaki in person, letting him know that Hidetoshi Daimon had been found, but he would return a few days later.

The Stone-Dong carried Daigo Nishijima to cyberspace and then to the real world.

The stubborn beast watched this scene very carefully.

It couldn't help but ask Bai Yu, "How exactly did you build this train?"

Bai Yu rolled his eyes and replied, "It's just an ordinary train with a little bit of ordinary dimensional power. Nothing too special."

Bai Yu answered Stubborn Beast on a whim, but it left Stubborn Beast with much to ponder now and in the future.

After that, Bai Yu temporarily settled down in Shangwu City.

This Shangwu City truly lives up to its name; the Digimon living here undergo various forms of training every day.

Logically speaking, given this environment, the Digimon here should be quite powerful overall.

In reality, the highest level of Digimon here is Champion; there isn't even a single Ultimate-level Digimon.

Of course, the stubborn beast was not included in Bai Yu's calculations.

Compared to the training of those Digimon, Bai Yu watched Daimon Hideki's training the most every day.

Shiraha thought that the reason why the stubborn beast was willing to train Omon Hide was probably because it wanted to study and experience the digital soul up close.

It must be said that, as expected of the father of the 'strongest Digimon', Hideaki Omon, with his Digimon Soul, was able to fight Omen to a standstill.

Although this is training, it also proves Daimon Hide's great talent.

However, this digital soul has both advantages and disadvantages. It can only enhance Daimon Hide's physical attributes and has no other effects. It has no attributes and cannot perform any ranged attacks.

Therefore, Hideaki Omon and Stubborn Monk learned close-combat techniques.

-----------------

Days passed by like this, and Daimon Ei made progress every day.

On this day, the stubborn beast was still sparring with Daimon Hideki.

Suddenly, the stubborn beast paused, and raised its head slightly.

Bai Yu, standing nearby, noticed the stubborn beast's subtle movements.

Then, the stubborn beast spoke up: "That's enough for today. You should strengthen yourself again."

Daimon Hideki stopped fighting. Although he didn't know why the fight had ended so early, he didn't ask any questions. Instead, he bowed to the stubborn beast and said:

"Yes, teacher."

The stubborn beast doesn't acknowledge the title of "teacher," but since Daimon Hideaki insists on calling him that, it doesn't care anymore; it just doesn't acknowledge it anyway.

Then, the stubborn beast left.

Bai Yu followed behind the stubborn beast, watching it leave the city.

A centaur-type Digimon with a horse's head and a human body, covered in red Digi-alloy armor, descended from the sky and landed in front of Stubbornmon.

“Sleipmon.” Bai Yu, who was following behind, immediately recognized the Digimon.

It is one of the Royal Knights, an Ultimate-level, Paladin-type, Vaccine-type Sleipmon, whose strength is rated as S-class.

Looking at Stubbornmon, Sleipmon's first words were: "It's been a long time, my dear friend."

The stubborn beast said, "It has been a long time, but I don't actually want to see you. Whenever you come to see me, it means you have something to say."

“My dear friend, please don’t say that, although what you said is not wrong.”

"Heh." The stubborn beast sneered, not wanting to waste any more time on nonsense.

"Just tell me what's on your mind."

Sleipmon's expression turned serious: "By order of the World Tree, I must take that human beside you back."

The stubborn beast's expression changed: "If he doesn't want to, are you going to forcibly take him away?"

Sleipmon said coldly, "The will of the World Tree cannot be disobeyed."

The stubborn beast sneered: "After all these years, you are still so ignorant, without your own thoughts."

“It’s because you like to run around aimlessly that your mind has been corrupted,” Sleipmon retorted.

Their argument did not continue, because the stubborn beast did not want to waste any more breath on these clichés.

The ability for them to change each other's minds is no longer something that can be achieved through language alone.

Seeing that Stubbornmon remained silent, Sleipmon, as a longtime close friend, immediately understood Stubbornmon's attitude. As expected, a fight was still necessary.

Just as Sleipmon was getting into a fighting stance, Stubbornmon spoke up again: "Put my opinion aside for now. Whether you can take him away or not, you'll have to ask the person behind you first."

The stubborn beast always knew that Bai Yu was following behind.

They didn't try to hide at all. With the strength of the stubborn beast, how could it not notice that there was a tail behind it?

Upon hearing what the stubborn beast said, Bai Yu simply stepped forward.

"It's him!"

Upon seeing Bai Yu, Sleipmon quickly recognized who it was.

After the Lucemon incident, Shiraha's fame soared to new heights, and every top Digimon knew him.

Bai Yu, who was behind them, had already understood what was going on.

He looked at Sleipmon, his tone icy: "The World Tree wants to study the Digital Soul? Ha, go back and tell it to put away its filthy thoughts. This is the power of humanity; it can't master it with just a computer."

Bai Yu's words instantly enraged Sleipmon.

"Human, even you, cannot disrespect the World Tree!"

"Hehe, I've already sparred with it several times, it's already an opponent, so there's no need for respect anymore."

Sleipmon was surprised, as was Stubbornmon.

They knew that Bai Yu was strong enough to defeat the Light Beast, and they had also felt the holy light that illuminated the world back then.

But they didn't know that he had fought against the World Tree (the adult), not even Sleipmon, who was still under the World Tree's command.

If this is true, then this person's evaluation needs to be changed.

But the evaluation can wait. For now, Sleipmon's task is to complete the mission assigned by the World Tree.

"Are you going to join him in stopping me, my close friend?"

Before taking action, Sleipmon asked Stubbornmon one more question.

"As I just said, I'll put my opinion aside for now." The stubborn beast jumped away to a distance.

Seeing this, Sleipmon secretly breathed a sigh of relief.

Then its gaze returned to Bai Yu: "Human, let me see if your strength is worthy of the legends you have left behind."

Bai Yu had already made preparations, and the [Onis Beast Card Set] was already in his hands.

"I guarantee you won't be disappointed, and you'll never forget it." As Bai Yu spoke, he held a small mirror that he had taken out of the system space in his other hand.

【Onis Beast Card Set】Aim at the mirror, and the V-shaped buckle will appear from the mirror at Shiraho's waist.

"Henshin!"

The armor emerged from the mirror and solidified into physical armor on Bai Yu's body.

[Digital Contract Knight Onis] Transformation complete, and the mirror was immediately returned to the system space after the transformation.

"The power of the Onis Beast!"

Both Sleipmon and Stubbornmon instantly recognized which Digimon power Bai Yu was using.

"You dare underestimate me!" Sleip Beast roared in anger.

It knew that when Bai Yu dealt with Lucemon, he didn't use Onismon's power, but a much stronger one.

"If you don't want me to look down on you, then you'll have to see how you perform!"

With a stomp of his foot, Bai Yu instantly cracked the ground and charged toward Sleipmon at incredible speed, his right fist clenched and punching out with all his might! Before the fist even arrived, the powerful gust of wind from the punch had already reached him.

But this had no effect on Sleipmon. It quickly raised its right hand and used its holy shield, Niflheim, to block White Feather's punch.

"Oh!"

The shockwave swept around, and the ground within a radius of thousands of meters beneath our feet cracked instantly!

"What immense strength," Sleipmon thought to itself.

"Oh!"

Another loud bang, and Bai Yu kicked Sleipmon's Holy Shield hard.

The immense force bent all six of Sleipmon's strong hooves.

Bai Yu used the recoil to fly into the sky, quickly pulled out a card, and put it into the reader.

"Weapons have arrived!"

The twin blades [World Destroyer Wing Blades] were summoned, and Bai Yu caught them with both hands, using the force of the fall to quickly charge up the blade's power!

Sleipmon wasn't going to be foolish enough to wait for Bai Yu's attack to land.

"Odin's Breath!"

Sleipmon shouted, and the Holy Shield [Niflheim] unleashed a blizzard of absolute zero, which hit White Feather directly and swept him away!

"Bang! Thud!"

A piece of solid ice fell to the ground; Bai Yu was frozen in ice.

"Rainbow Bridge and Fierce Arrow!"

Sleipmon immediately raised the Holy Crossbow [Muspelheim] in its left hand and fired a high-temperature, scorching light arrow.

The arrow of light shot towards Bai Yu like a rainbow!

The solid ice shattered from the inside just before the light arrow was fired, and at the same moment, an electronic sound effect rang out: "The contract has been made!"

Machine Onismon appeared, its massive body blocking Bai Yu's path. Its enormous wings folded, taking the full force of Sleipmon's sword strike...

Chapter 686: Now that the decision has been made, let's take action!

Previously, Bai Yu was idle and didn't think to ask these questions, but now he must ask them properly.

Daimon Ei answers whatever is asked:

"As you know, I don't know much about Digimon, but I do know that SaberGreymon is an Ultimate level."

"The two Digimon that SwordLeomon possessed were also Ultimate-level Digimon; SwordLeomon called them Boltmon."

"There are many Digimon in Blackrock City; it is a rather prosperous steel city."

"At first, the Saber Lion Beast only wanted to take me there to inquire about returning to the real world, but in the end..."

At this point, Daimon Ei's mood sombered, and she lowered her head.

Bai Yu understood that he was blaming himself for the death of the Sword Lion Beast, feeling that the Sword Lion Beast wouldn't have died if it weren't for him.

No wonder he's so eager for revenge; that must be a big part of it.

After a pause, Daimon Hide continued, "At first everything was fine, but then suddenly several guardian robot beasts came to capture me, saying that all humans should be wiped out as well."

"The sudden turn of events left me completely bewildered. I tried to explain, but the Digimon from the Steel Empire simply wouldn't listen."

"The sword lion had no choice but to protect me and fight our way out of the city."

"But those Digimon from the Steel Empire wouldn't let me go. They chased me out, and there were even more and stronger Digimon coming."

"After that, SaberGreymon died from the attack of two Boltmon, while I was rescued by a passing Stubbornmon."
