I became a god by treasure hunting after arriving 500 years early

Lu Yuan narrowed his eyes; the gate was made of a material called "tungsten steel," so sturdy as to be terrifying, unable to be broken by brute force. Without much hesitation, he spoke softly, "I'll spatially jump past the door, open it, and you hide in the Mirage Space. If there's a huge danger inside, I'll send a signal, and you fire immediately, then evacuate as soon as possible." "Don't worry about me, I also have Space Ability, I'll find a way to escape." "Alright, let's begin. We must kill the mastermind as soon as possible!" Lieutenant Sha Kan'er and the other two hesitated but eventually had no better solution and could only agree to this straightforward tactical plan. They started adjusting the Source Fire Cannon, aiming its barrel at the metal gate, meanwhile loading up the ammunition. Lu Yuan also took a deep breath and checked his weapons and gear. He was carrying a "Spirit Rune," an "Explosion rune," and a "Conch Buff Rune," along with various bombs and other explosive Technology Weapons. There was no choice; the production capacity for these runes was too low. He had to reserve some for the two battlefields in the rear. Of course, to compensate for the lack of fighting power, he brought a drop of [Ghost]'s blood! After all, in this war, they could only win, not lose! He felt that he might not be able to defeat the bizarre creatures from the previous Epoch, so he brought this trump card with him. Even if he had to release the drop of [Ghost] blood, there was no choice. A mutual destruction could also be considered a good outcome! Having made up his mind, he took out the "buff rune meticulously crafted from a Conch," and after activating it, the rune burst into a burst of colorful light. He calmed his spirit, passed through the spatial film, and landed on the floor. Even the floor was constructed with that mysterious Crystal Stone. In just an instant, as soon as the existence of an outsider was noticed, the abundance of Crystal Stones started to change, each lighting up! Lu Yuan had a mysterious sensation, as if some unknown entity was observing him through these Crystal Stones. The very next moment, an extreme sense of danger surged into his heart! Dense and dazzling light lit up, and a large amount of high-energy lasers swept across! The speed of laser emission was the speed of light, truly surpassing human reaction times, and even though Lu Yuan used Different Space immediately, he was still hit by several lasers! "Hisss—These lasers are so fierce?" he gasped. It was fortunate that he was wearing Superior Level Yingyu Armor, or he would have been riddled like a beehive! The lasers, reaching hundreds of millions of degrees, pitted and dented the armor, one even hitting Lu Yuan's neck, burning a hole the size of a peanut. If not for the strong protection of his Eternal Spark, his throat would have been pierced! "What can be done? I'm fast, but I cannot match the speed of light." While Lu Yuan was pondering, he suddenly saw a black shadow from Mirage Space throwing out a black can. This can emitted a thick black smoke—a Smoke Bomb! Countless lasers shot towards the can. The previously trackless lasers now left trails of orange-red afterimages in the black smoke. In less than a second, the can completely melted, but the rising black smoke did not dissipate in a hurry. "I see, smog to defend against lasers!" Lu Yuan quickly understood his companions' thinking; although this method was crude, it indeed worked! No matter how powerful the lasers, once hindered by smog, their Energy greatly diminished, and getting hit a few times didn't mean much. Immediately after, more Smoke Bombs were tossed from Mirage Space, and thick black smoke appeared in the crystal corridor. As the dust rose, Lu Yuan took out a shield from Storage Space to protect his back, his body erupted in red light, and he performed Spatial Teleportation, moving in front of the gate. An innumerable amount of lasers shot towards him in that instant! But once their energy was weakened by the smog, the Large shield was finally able to provide protection. He used the sensation from Eternal Spark to gauge the thickness of the door and then instantly teleported behind it. Inside... Was it really another dark metallic corridor? However, it seemed there were not that many laser weapons. Lu Yuan quickly turned on his flashlight and began to search for the door's switch. Contrary to his expectations, this gate was actually mechanically locked! There was a handle that could be directly turned, but it required an immense amount of strength to twist this valve-like structure. This perplexed Lu Yuan—shouldn't a civilization with such advanced technology use electronic locks, or some other more sophisticated tech? But there was no time to ponder excessively; the Little Mirage Dragon came over with its Mirage Space. Lu Yuan got back into the Mirage Space and shared his suspicions. "Could it be possible that the one controlling all this is actually a Strong AI?" Lieutenant Sha Kan'er slapped his forehead, conceiving a theory. "The civilization that created the flying saucers has always been wary of AI rebellion, hence, traditional mechanical locks are more reliable than electronic ones." "After all, AI is just a computer; it has no body." "But over time, after the demise of the flying saucer civilization, the AI still found a way. It controlled the outside world's South Island Civilization through chips, and the South Island Civilization possesses some incredibly high-tech weapons. Otherwise, the South Island Civilization would not be our match." "It makes some sense," nodded Lu Yuan, "but what about that Mind fluctuation? An AI shouldn't possess Mind fluctuations…"
