In a few moments, the huge golden silkworm chrysalis all turned into streamers and burrowed into the golden spar on Allen's chest. Alan lowered his head in surprise, but he didn't feel any discomfort, and even he couldn't feel the presence of the energy body.

"That's it?" Alan asked tentatively.

"Let's go, my evolution has reached the most critical moment, I will wake up on my own in three days, and before that, if you die, I will die with you, understand?" After the energy body finished speaking, it stopped speaking and fell silent in the golden energy crystal on Allen's chest.

Alan let out a sigh of relief, his worst concern was finally solved, and the most important thing now was to evacuate safely. He rushed towards the exit of the lab.

"Winter wolf, the energy silkworm chrysalis has arrived, now immediately evacuate to the outside of the castle." Alan sent the signal through viral communication!

"You'd better get over here as soon as possible, I'm entangled." The Winter Wolf's angry voice rang out.

As soon as Alan rushed out of the underground laboratory, he heard a loud explosion coming from the city gate, and Alan hurried over. No sooner had he reached the main road than he saw Kramer standing at the head of the city, turning a cannon around and blasting it into the walls. Sabnis flew in mid-air, dodging constantly, and behind her, a humanoid creature had bone wings growing from its back, chasing after Sabnis.

The Winter Wolf was even more embarrassed, and several humanoid creatures who fought with him had short spears drilled out of their fists, and they actually began to fight with the Winter Wolf in close combat. Judging from the fact that these humanoids relied on their powerful self-healing abilities and did not have any combat skills, Allen originally thought that they were just creatures that relied on their own instincts to fight, but now it seems that these humanoid creatures have a strong ability to imitate and learn, or they can achieve self-evolution according to the abilities of their opponents.

Alan raised his head and looked at Alexia in the sky: "Help Sabnis and take that monster down." ”

As soon as the words fell, a thin line of fire landed out of thin air. Blasted the humanoid creature chasing after Sabnis in the middle of it, burning its chest with the force of the impact.

"Sabnis, we're buying you time, we need more self-detonating bugs, just stop these monsters from chasing and killing, we can evacuate safely."

Alan said, already rushing into the warband, the Shadow Blade with a golden energy pattern, fiercely slicing into the neck of a humanoid creature. Then Alan raised his right foot and kicked the opponent directly.

"Kramer, get back on board the Aegis, and get the airship ready, we're ready to evacuate."

Kramer, who was on the wall, jumped off the wall after receiving Allen's order, and then rushed into the distance.

Eren explained everything, and then he and the winter wolf blocked the siege of the humanoid creatures back to back. Sabonis, on the other hand, flew up and sat down behind Alexia and began to gather her strength.

Lines of fire erupted from the volcano, and Alexia held her alchemy sniper rifle steadily. Bomb the flying humanoid creature into the air. No matter how strange the opponent's flight trajectory is, Alexia can hit the place with unmistakable accuracy.

Sabnis closed her eyes and clasped her hands together, an unknown energy condensing between her hands. Alexia looked back in surprise and saw Sabonis's hands slowly parting, and a milky white flesh worm appeared out of thin air. Sabnis snapped open her eyes and threw the worm away. The moment when this flesh worm leaves its body. Sabnis's face turned pale instantly, and she immediately fell unconscious. Alexia's eyes were quick, and she hurriedly secured her behind her. Then he turned around and fired a shot, blasting the flying humanoid creature into the air again.

The flesh worm grew in mid-air, and when it fell to the ground, it had grown into a behemoth with a body of more than ten meters. The body of the flesh worm smashed the city wall, and even crushed several cannons under it, and huge cracks were smashed into the city wall, and the rubble kept falling to the ground.

The flesh worm let out a chirp, and then the huge body swelled up, and the tail of the meat worm suddenly raised, curling and almost touching the position of the head, and the next moment the tail suddenly opened a flesh hole, and then spewed out huge eggs with a diameter of fifty centimeters.

"Withdraw!"

Eren grabbed the winter wolf, and then threw him directly out of the city with one arm, and then Allen's fists suddenly raised, and then slammed into the ground, and a visible ripple of golden energy roared out, shaking all the humanoid creatures backwards. Alan jumped up at this moment and jumped directly out of the city gate.

Alexia in the sky also blasted out of the line of fire again, blasting the flying monster into the monster pile.

Insect eggs poured into the blood-colored castle, cracking open as soon as they touched the ground, burrowing large self-exploding beetles. These beetles are pitch black, with an almost blinding metallic sheen on their carapaces. Without hesitation, they rushed into the monster pile, and then began to blow themselves up.

The flesh worms on the city wall sprayed eggs for nearly three minutes, and then their entire bodies began to dry up. When it spews out the last egg. The body lost color in an instant, and then it disintegrated into a cloud of dust.

Countless explosions rang out, and the entire ground began to shake. Allen, who was running, couldn't help but turn around and look at the top of the burning mountain, and then his speed increased a few points again. The Aegis airship had been preparing for a long time, and by the time Eren stepped onto deck, Alexia, the unconscious Sabnis, the Winter Wolf, and Kramer had all arrived safely. Eren finally let out a long breath and said to everyone.

"Homecoming!"

Three days later, a fully equipped airship brigade flew in from the distant sky. The huge and centered airship was hundreds of meters long, with golden ornaments covering the entire hull, and a round shield emblem directly in front of the airship was particularly eye-catching. Twelve-sided golden solar sails provide all the power the airship needs.

In addition to the main airship, there are a total of eight frigates divided into four groups to guard in four directions.

On the deck of the main airship, the chief head of the Knights, Kersma, stood straight, but his originally thin body gave people a strong sense of oppression like a mountain at this moment. Behind him, a gray-haired middle-aged man stood silently. The middle-aged man had a tough face, wearing a heavy armor of jet-black, and a swarthy two-handed sword behind his back. Even as he stood so simply, a faint blood-colored mist swirled around him, adding an eerie haze.

"Chief Commander, the battle ahead is tight, and we are retreating one after another, why are you recruiting me back at this time?"

"Mordred, this time it happened suddenly, so I need you to take action." Commander Kersma said, staring at the approaching blood-colored castle.

"For what?" Mordred asked, puzzled.

"Capturing a new species is enough to perfect our X plan for a new species!" (To be continued......)
