S.H.I.E.L.D. Triskelion Headquarters, Nick Fury's office was filled with a solemn atmosphere. Avengers's holographic images gathered in a circle, listening to Fury's latest briefing.
"It's not Kree, it's not Skrull, it's not some underwater civilization." Fury called up a blurry surveillance video, "Look at this."
The video shows a familiar figure - Kaecilius wearing a yellow jersey, who was once a traitor to Kamar-Taj. But he looks different, with an ominous red light flashing in his eyes, and the magic he uses seems to be mixed with some kind of technological energy.
"Kaecilius?" Strange frowned, "This is impossible. I witnessed him being swallowed by Dormammu."
"Apparently he found a way back," Fury called up the energy reading again, "And brought... friends back."
The new screen shows Kaecilius followed by several figures. They all wear armor that combines magic runes and technological equipment. The energy used is neither pure magic nor technological weapons.
Tony touched his chin. "This energy signature looks familiar..."
"Ten Rings's remaining technology," Banner suddenly said, "Look at the devices on their arms - that's an improved version of Mandarin's technology."
Natasha added, "According to intelligence, Kaecilius came into contact with the exiled scientists of Ten Rings during Dark Dimension. They seemed to have reached some kind of... cooperation."
Suddenly, the alarm sounded. Hill's voice came from the communicator. "London Sanctum Sanctorum is under attack! The energy reading matches Kaecilius!"
Strange immediately opened the portal. "I must go."
"Wait a minute," Steve stopped, "This is obviously a trap. They know you will definitely rescue Sanctum Sanctorum."
Tony nodded. "The captain is right. We need a plan..."
Before he finished speaking, Strange had already stepped into the portal. Avengers could only follow immediately.
London Sanctum Sanctorum has fallen into chaos. Kaecilius and his new accomplices are fighting the mages led by Wang.
But this is no ordinary magical battle - Kaecilius's minions use strange devices that absorb magical energy and convert it into some kind of destructive energy.
"They are using anti-magic technology!" Wang shouted, holding up the protective shield.
Strange joined the battle, and Bands of Seraphim entangled an enemy. "Kaecilius! Where did you get these technologies?"
Kaecilius sneered, "There is a lot of forgotten knowledge in Dormammu's dimension, Strange. For example, how to integrate magic and technology..."
He raised his hand and shot out a red and black energy beam, which was neither pure magic nor a technological weapon. Strange's protective spell was actually partially absorbed.
Tony and Rhodes provided support from the air, but their energy weapons were also strangely absorbed and transformed. "Friday, analyze the energy pattern!"
"Analyzing... the energy signature shows a mixture of magic and Ten Rings technology... is adapting to our attack pattern..."
On the ground, Steve and Natasha tried to evacuate the surrounding civilians, but Kaecilius's men set up a space blockade.
"Need support!" Clint shouted from the commanding heights, "These guys' equipment can predict my shooting trajectory!"
Wanda's Chaos Magic seemed to be more effective, but she also found it difficult. "They are absorbing my energy... still learning how to counterattack!"
Thor summons thunder and lightning, but the lightning is directed towards strange devices. "These inventions are starting to annoy me!"
Just when the battle situation reached a stalemate, Kaecilius suddenly laughed, "That's enough! Data collection is completed!"
All attacks suddenly stopped, and Kaecilius's men simultaneously retreated into a dark portal that suddenly opened.
"They are not here to fight," Banner analyzed the remaining energy, "They are testing something..."
Strange inspected Sanctum Sanctorum's damage. "They are looking for a specific energy frequency..."
Suddenly, all Sanctum Sanctorums sounded alarms at the same time. Hong Kong, New York, and Sanctum Sanctorum were all attacked similarly, with the same pattern - immediate retreat after a test attack.
"What are they looking for?" Wang asked confused.
Tony suddenly thought of something, "Friday, call up the energy reading comparison of Wakanda..."
The results showed a striking similarity. "They are looking for magical fluctuations that are similar to the energy frequency of Vibranium."
T'Challa's holographic image access. "Wakanda's Vibranium vein has detected abnormal energy resonance. Something is trying to establish a connection with the Vibranium energy."
At this moment, on Malibu Beach, Xiao Han turned over impatiently. Abnormal energy fluctuations around the world were buzzing in his perception like mosquitoes.
"It's endless..." He finally sat up, a red light flashing in his eyes, "What's it about this time?"
His Super Vision swept across the world and finally locked in the direction of Wakanda. The energy anomaly there was the most obvious - some kind of energy that combined magic and technology was trying to activate something deep in the Vibranium vein.
"Interesting." Xiao Han raised his eyebrows, but then lay back down, "But it has nothing to do with me."
He adjusted the position of the beach chair and prepared to continue basking in the sun. Until his Super Hearing captured the communication of Tony deploying fighter planes.
"... All personnel need to go to Wakanda. If they are allowed to activate the thing deep in the Vibranium vein, the consequences will be disastrous."
Xiao Han sighed. He remembered that the energy frequency of Vibranium's mineral vein in Wakanda was extremely stable, and it was one of the best places for him to bask in the sun.
"Trouble." He muttered to himself and finally stood up.
In the sky above Wakanda, the fighter plane of Avengers was preparing to land, when suddenly a golden light flashed across.
"Wait a minute," Tony said in surprise, "He actually came on his own initiative?"
Xiao Han was suspended above the Vibranium mineral vein, looking at the ongoing ritual below. Kaecilius and his men were using a strange device to try to activate something deep in the mineral vein.
"What are you playing for? Take me with you." Xiao Han's voice was not loud, but it reached everyone's ears clearly.
Kaecilius raised his head, with a crazy light flashing in his eyes. "Sun's Son! Just right! We need your energy to complete the final activation!"
Xiao Han didn't even respond. With a sweep of Heat Vision's eyes, the ritual device melted instantly.
"No!" Kaecilius roared, "You don't know what you are destroying!"
Xiao Han Another Heat Vision, this time directly hitting the surface of the Vibranium mineral vein, instantly solidifying the fluctuating energy.
Kaecilius and his men still want to resist, but Wakanda's army and Avengers have surrounded them.
The battle ended quickly. Kaecilius was subdued by a special energy restraint device, and all his men were arrested.
Strange inspected the ruined ritual site. "They are trying to activate an ancient existence... something sealed deep in the Vibranium mineral vein."
T'Challa looked solemn. "Wakanda's legend mentioned 'Earthcore God', but we always thought it was just a myth."
Tony walked up to Xiao Han: "I didn't expect you to come to help."
Xiao Han glanced at him: He looked at the Vibranium mineral vein, "And this is one of my favorite places to bask in the sun."
Just as he was about to leave, a faint heartbeat-like vibration suddenly came from deep in the mine. Everyone was stunned.
"What is that?" Natasha asked warily.
Xiao Han frowned and looked at the ground. "Someone... was woken up." A trace of interest flashed in his eyes, "Maybe it's not so boring anymore."
But he immediately returned to being cold. "But it has nothing to do with me." He turned into golden light and disappeared.
T'Challa and Strange exchanged worried looks.
"We need to talk about that 'Earthcore God'." The two said in unison.
And deep in the mine veins, the ancient existence seemed to have fallen into a deep sleep again, leaving only a faint trace of energy fluctuations, hinting at future troubles.
