I'm working on Marvel's Spider-Man in American comics.

Chapter 344 The Border of Hell Changes Hands
"In the name of Sisyphus..."

When they heard what Strange was saying, the few people present who knew magic couldn't help but look at him. Dejected Strange stepped forward and explained, "He's using necromancy. After all, a dimensional demon god has died in his own domain. By offering this as a sacrifice, he can obtain a large amount of mana for free."

Necromancers use death as the source of their magic. Although Velasco is immortal, he can still be killed, so Strange seized the opportunity to begin casting his spell.

Although Velasco is not actually dead yet.

"Now!"

Crimson chains pulled away Velasco's left hand, and Iliana swiftly severed his head, then crushed it with a stomp. Strange immediately cast a spell, and as a gust of wind swept through everything, Strange let out a long breath.

Tony looked around, opened his visor, and remarked, "That's it?"

"Temporarily yes. The spell severed Velasco's connection with the Borderlands for a very short time, but he remains the master of the Borderlands, and his spirit is closely connected to this place."

Strange breathed a sigh of relief, wiped the sweat from his brow, and continued, "Velasco might be resurrected in one of the universes he corrupted, but not here. I'll be here for a while longer to deal with the rest of those things, those corrupted demon versions of the X-Men."

Strange didn't specify how he would deal with those guys, because it would be inhumane to say so. He planned to sacrifice all the corrupted X-Men as casting materials, and use the extracted mana to completely sever Velasco's connection with Limbo.

From then on, Velasco's relationship with Limbo was like that of Gnar's consciousness and his body, or even worse. After all, if Peter or Venom were killed, Gnar could return, but Velasco, who died outside, could only be resurrected outside and could not return to Limbo.

"As long as the spells at the border of hell remain stable, just in case, someone needs to be stationed here to oversee things..."

"I'll do it." *2
One of those who said this was the dejected Strange, who never thought he could survive and whose reality had long since collapsed. He figured he might as well stay on the frontier and become the Sorcerer Supreme, protecting it from the threat of Velasco's return.

This was originally the person Strange thought was the most suitable, but unexpectedly someone else came up for the offer, so Strange looked over there.

“Miss Iliana… I have to admit, you do have this talent, and if fate hadn’t intervened, it certainly would have been yours…”

If fate hadn't intervened, the X-Men would have rescued Iliana after she was taken away and tried to stop Velasco's invasion. In the end, the X-Men would have stopped Velasco, but they wouldn't have been able to rescue Iliana.

Then, on the border of Hell, Iliana becomes Velasco's apprentice, while simultaneously contacting the Rebel Alliance and learning both white and black magic from both sides, while also awakening her mutant abilities. Velasco discovers all of this, and in the end, Iliana and the Rebel Alliance choose to fight to the death.

"Everyone is dead, except you. You successfully banished your teacher, Velasco, and began to merge your soul with the borders of hell, attempting to replace Velasco..."

"I can still do it, can't I?"

Strange paused for a moment. Indeed, it was possible. Iliana still had half of her soul that hadn't returned to her body. As long as the Soul Sword was bound to the Borderlands, although it couldn't replace Velasco, it could completely weaken his power.

But the root of everything was originally to break free from fate, so isn't this just going back to square one?
“I… I’ll cast the spell here first. Then Miss Iliana and the other me will stay here. We need to discuss this. Oh, and that Blade. He’s a vampire; he can’t get out without magical protection. It’s better for him to stay on the edge of hell.” Peter glanced at Strange, wanting to say if he could help, but Strange slapped him with his levitation cloak without warning: “Go back now. Seeing you gives me a headache.”

"Um, well... I'll be going now?"

Peter scratched his head, passed through the golden portal, and returned to Avengers Tower. Meanwhile, the X-Men also traveled back to the Academy. The Avengers, including Hulk, collapsed to one side. Janet simply sprawled on the sofa; the wings of her suit had been torn by Velasco and now needed repair.

"So, this is our last mission before Christmas. The Avengers have saved the world once again. Hooray!"

She called out weakly, and Hulk, the only one who couldn't get on the sofa and was sitting on the floor, pouted and said, "Hulk wants fried chicken."

"Are you alright, Captain?"

Peter, who was lying on the sofa, looked at the captain. Everyone present had seen Captain Rogers being stabbed by Velasco, but the captain himself felt okay: "I feel... a little tired, and it still hurts, but that's about it."

"A true warrior can endure any pain, even pain from the soul."

Thor was the only one not sprawled on the sofa. He leaned against the refrigerator and opened a can of beer: "Many of Asgard's enemies can use soul attacks, and the Avengers may encounter them in the future, so... we need to prepare in advance."

"I suggest we don't think about anything."

Tony finally voiced his thoughts, feeling like he'd almost been roasted alive inside his armor: "Just focus on getting ready for tomorrow's Christmas party. As for what we're having, Turkish kebab is out of the question; that place is awful."

Xavier Academy for Gifted Youngsters.

Having become a support staff member and never leaving the area, Beast rushed to greet his teammates upon seeing the golden portal appear. After he left, in the X-Men's underground airfield, the Blackbird's systems finally seized the opportunity and began to operate automatically.

The virus planted by Otto Octavia was activated in that instant and transmitted to the underground central system of Xavier's Genius Academy. Following the pre-set procedure, it attempted to steal data from the brainwave analyzer, but abandoned the attempt after finding the defense level too high.

Next, the virus program began to crack and analyze the operating program of the danger chamber, discovering a large number of data errors, suggesting that this part of the technology did not originate from Earth.

"Okay, hmm? System speed... oh, it's normal."

Beast returned to the lab, glanced at the computer, and confirmed that nothing had happened. The program was simply waiting for the next time the entire X-Men were deployed.

Before this, it would only silently execute copy commands.
