A legion burst out at the beginning of the super card system

Chu Mu took out the last vitality card, with a fortress drawn on it.

"Ding! The system found a kind of building card. After using it, a fortress will randomly appear. There will be treasures in the fortress, and there will be guardian beasts that match the fortress. Is the host activating the fortress?"

The system prompt sound appeared in Chu Mu's mind.

Chu Mu was taken aback. He had never heard of building cards, let alone seen fortresses. He was curious, so he said, "Activate!"

"Ding! Congratulations to the host for activating the bronze fortress, please be careful with the guardian beasts inside the fortress."

I saw a fortress appearing in a huge cave.

On the front of the bronze fortress, there is a portal.

Without hesitation, Chu Mu pushed open the door and walked in.

The space in front of me was like a black hole, and it was pitch black and nothing could be seen.

A strong suction made Chu Mu involuntarily move forward, not allowing him to retreat.

Although Chu Mu had a one-star bronze combat power, he still had no ability to resist, and entered the space of the bronze fortress all at once.

"Ah! It hurts! It hurts! It hurts..."

In an instant, Chu Mu felt severe pain, and his body seemed to be torn apart.

It was as if his entire body had been turned into blood mist, and he lost consciousness in an instant.

Everything is like chaos.

"Who am I? Where am I? What am I going to do?"

Accompanied by a burst of pain, Chu Mu finally woke up.

But when Chu Mu saw the environment in front of him, he was taken aback. Where is this?

Suddenly, Chu Mu felt a splitting headache and couldn't bear it, so he stopped recalling.

"Where is this? Who am I? What am I doing?"

It seems that Chu Mu has lost his memory.

At this moment, a ray of light flew out, extremely fast, and flew to Chu Mu's side in the blink of an eye.

Chu Mu slashed out the Soul Slaying Knife, cutting the flying light in two at once.

Taking a closer look, the one that was cut in two turned out to be a big insect with six pairs of flying wings.

After the big bug was cut in half, two smaller flying insects formed in the air, and the two flying insects stared at Chu Mu.

Chu Mu was frightened and took a few steps back. He felt that the two flying insects in front of him were very powerful and dangerous.

"Master, what's wrong with you?"

Chu Mu was taken aback, and stammered, "Is it a goblin?"

"Haha!" Fei Chong laughed loudly, "Master, don't panic, I am the ancient Zerg, the guardian elf of the Bronze Fortress."

"Ancient Zerg?" Chu Mu thought for a while, and suddenly had a headache.

"what!"

A ray of light was seen from the flying insect, shining on Chu Mu's head.

After being illuminated by the light, Chu Mu's headache completely lost its pain.

"What exactly is going on?"

The ancient Zerg described everything about the Bronze Fortress to Chu Mu.

"I see!"

Following the description of the ancient Zerg, Chu Mu remembered many things.

"So, this bronze fortress is now my territory, and I want to see what treasures are inside." Chu Mu said as he was about to walk into the depths of the bronze fortress.

At this time, a black bead fell to the ground.

"Hey, what's the use of this bead?" Chu Mu asked, picking up the black bead on the ground.

The ancient Zerg merged into one, turned back into a big bug with six wings, and landed on Chu Mu's palm.

Looking at the black beads, the ancient Zerg suddenly said in surprise: "Master, this is a space item. You have found a treasure. With a little crafting, it can become the key to travel back and forth through the bronze fortress."
