The black - clothed men swarmed in like a tide. The weapons in their hands glistened with a cold light, and their eyes were filled with fierceness and determination. I quickly surveyed the surrounding environment. The limited space in the basement was a disadvantage for our battle, but it also restricted the enemy's numerical advantage.
"Everyone, back to back and form a defensive circle!" I shouted loudly. The team members quickly took action, tightly protecting the catalyst in the middle.
The black - clothed men launched the first attack. Bullets rained down on us like a storm. We all rushed to find cover and fired back at the same time. The intense gunfire echoed in the basement, and the smoke filled the air.
"Captain, their firepower is too strong. It's hard for us to suppress them!" Tom shouted. His voice was partly drowned out by the gunfire.
I looked at the team members around me. There was tension and determination on everyone's faces. "Don't panic. Save your bullets and shoot when they get closer!" I shouted.
Just then, a black - clothed man took advantage of the moment when we were dodging the bullets and suddenly rushed towards me. He waved a long knife and slashed at me. I quickly dodged to the side and kicked him in the chest, knocking him to the ground.
"Watch out behind you!" Kevin suddenly shouted. I looked back and saw two more black - clothed men charging from the side. Without thinking, I quickly drew my pistol and fired two consecutive shots, knocking them down.
However, the number of enemies was increasing, and we were gradually struggling to hold on. "This won't work. We have to find a way to break through!" I said.
Just when we were in a difficult situation, there was a sudden loud explosion. One of the team members had detonated a grenade, creating a gap in the enemy's ranks.
"Seize the opportunity and break through!" I shouted and led the team members towards the gap.
We broke through the enemy's defense line and ran towards the exit of the basement. But the black - clothed men didn't give up the pursuit. They chased after us closely.
"Captain, the exit is blocked!" a team member shouted. I looked up and saw that the exit was filled with debris. Obviously, it was an obstacle deliberately set up by the enemy.
"There's no time to clear it. Take the side passage!" I pointed to a narrow passage beside.
We quickly got into the passage. It was so narrow that only one person could pass through at a time. The black - clothed men couldn't pursue in large numbers and could only send a few people to follow behind.
"Everyone, be careful. There may be traps in the passage!" I reminded. We walked forward cautiously. Suddenly, there was a sound of mechanical rotation in front.
"Bad, there's a trap!" I shouted. Before we could react, a row of spikes protruded from the wall. We quickly stepped back, but still, one team member was scratched on the arm by the spikes.
"Dress his wound first and keep moving forward!" I said. We continued to grope forward in the passage. Finally, there was a door at the end of the passage.
"Behind this door might be the exit," I said. I carefully approached the door and listened to the movement inside. Hearing no abnormal sound, I slowly pushed the door open.
Behind the door was a spacious room filled with some ancient instruments and equipment. However, to our surprise, there was also a group of mechanical monsters in the room.
"How come there are still mechanical monsters!" Tom exclaimed.
These mechanical monsters were even taller and more powerful than the ones we had encountered before. Their bodies glistened with a metallic sheen, and their eyes emitted a red light.
"Everyone, get ready for battle!" I shouted. We once again took up our battle stances and engaged in a fierce battle with the mechanical monsters.
The attacks of the mechanical monsters were very fierce. Their fists were like hammers, and each blow could generate a huge impact. Our team members fought hard, but still, many of them were injured.
"Captain, if this goes on, we'll all die here!" Kevin said anxiously.
I looked at the mechanical monsters in front of me and felt a bit anxious. Suddenly, I remembered the crystal we had brought back from the ancient relic. "Maybe the energy of the crystal can deal with these mechanical monsters!" I said.
I took out the crystal and concentrated on feeling its energy. Suddenly, the crystal emitted a dazzling light, and a powerful energy gushed out from it.
The mechanical monsters seemed to sense the threat and stopped attacking one after another, looking at us warily.
"Everyone, join me and attack them with the crystal's energy!" I shouted. The team members gathered around me, and together we released the crystal's energy towards the mechanical monsters.
The powerful energy rushed towards the mechanical monsters like a torrent. The mechanical monsters fell to the ground one after another under the impact of the energy, making a shrill scream.
"We did it!" I shouted excitedly. Taking advantage of the moment when the mechanical monsters were on the ground, we quickly passed through the room and found the exit.
When we walked out of the basement, it was already dusk. The afterglow of the setting sun shone on the ground, adding a touch of solemnity to the ruins.
"Let's go back to the base with the catalyst quickly!" I said. The team members nodded, and we carefully left the ancient relic and set foot on the way back to the base.
On the way back, we were on high alert all the time, fearing that we would encounter another enemy ambush. After several days of arduous trekking, we finally returned to the base.
At the base, Lynn and other researchers were anxiously waiting for our news. When they saw that we had returned safely with the catalyst, they all breathed a sigh of relief.
"Great, you're finally back! With this catalyst, we have a hope of developing weapons to fight against the mysterious organization!" Lynn said excitedly.
In the following days, the researchers worked around the clock. They combined the catalyst with the crystal, trying to extract the crystal's energy. And we team members carried out high - intensity training to prepare for the upcoming battle.
We knew that the mysterious organization wouldn't give up their conspiracy easily, and an even more intense battle was still waiting for us...
