Lin Yi reached his hand out to touch the wall, only to find that his palm was buried in the rock. "Hehe ... It's a fake mountain wall! A 3D projection?" Lin Yi felt the cold metallic touch on his palm and shook his head,"It seems that this is Central's base!" After mumbling to himself, Lin Yi turned into his essence spirit and went in silently. Behind the virtual mountain wall was a huge, heavy steel door with the most modern locks, but Lin Yi didn't need to open it at all-his spirit floated in. Behind the gate was a steel-cast passage, and LED lights were installed at intervals along the passage. It looked very sci-fi, and it shouldn't have appeared in a place like Sky Class Island. Other than the center, no one would build such a building. Lin Yi sent out his spirit sense, but he didn't find any signs of life. This made his heart sink! Of course, it was possible that the scanning was blocked by a divine sense blocking device, so Lin Yi quickly flew through every tunnel and entered every room he saw, and the results were the same! In this base, there was not a single person or living being! That damned grey bamboo hat. It seemed like he had immediately led his men out of the base after he had discovered that he had appeared in the mountain region! He gave up just like that. He didn't even care if this place was an important stronghold that had been in operation for a long time. The man with the gray bamboo hat was really decisive! The problem was that once central left, the lead to Paradise Valley and Wang Xinyan would be cut off again ... He still had Ding Yi and Xue Peng as backup, but he wouldn't be at ease until he solved the problem! Lin Yi finally stopped at the central control Hall of the base. This place seemed to have just experienced a storm, and there were destroyed equipment everywhere. It seemed that the people in central had evacuated in a hurry, and the things that could not be taken away were destroyed. There wasn't much else, but there was one thing that Lin Yi was concerned about. "Senior ghost, come out and take a look. Is this a teleportation formation?" Lin Yi was talking about a big disc that stood in the middle of the control Hall, about five meters in diameter. There were some traces of a formation around it, but it looked damaged. Lin Yi wasn't sure himself, so he needed the guy to do the appraisal. The ghastly thing took a few glances and nodded with a solemn expression.""According to this old man's judgment, this is indeed a teleportation formation, but it's not quite the same as the ones we know of." The ground around the metal disk was engraved with complicated array patterns. With the damn thing's research on teleportation arrays, it could easily distinguish them. "The teleportation formation on the ground is only a part of it. It's still intact and hasn't been destroyed. However, it's impossible to use the teleportation formation with just this. Only with this metal disc can the teleportation effect be activated." The demonic thing's spirit sense carefully scanned the formation patterns carved on the disk, and it couldn't help but exclaim,""I can't believe that array techniques can be used in such a way. I've really opened my eyes today!" "Senior ghost, this disc seems to be a product of Science and Technology, not a formation tool created by a forger. Are you sure this is a teleportation formation?" Lin Yi took a deep breath, still in disbelief."Could it be that the central government has already developed a way to replace the formation with technology?" "I don't think they've been completely replaced. Look at the formation markings around. If they could replace all the formation markings, there wouldn't be a need for these formation markings! Furthermore, there are also formation patterns on the round plates, which is why they are connected as one!" The ghastly thing paused for a moment and sighed with emotion.""However, it is undeniable that technological methods have already replaced many other methods in this teleportation array. The ratio of the two is about four to six!" Formation technique (4), technology (6)! To be able to do this much was already quite amazing, and Lin Yi felt that his evaluation of central should be raised by a few more levels! The threat at the center was getting bigger and bigger! "Senior ghost, can we use this formation? The people in the center might have left this place through this teleportation formation!" Lin Yi touched the disc-the metal surface was cold, and there were some LCD touch screens on it, but they didn't show any signs of activation."If we can use it, we'll be able to catch up to the people in the center!" "It's a pity that this thing has been destroyed. If I want to restore it, it's far from enough to just have the ability to use arrays. I also need enough technology!" The demonic thing felt a little regretful. He was extremely interested in new things related to arrays, but he could not restore this disc by himself. He was blind in terms of technology. "Keep it first and study it slowly. I'll look for Jing Jing later to take a look!" He said. Lin Yi said as he moved the disc into the Jade space-it'd help him understand Central's strength. 𝒇𝙧𝙚𝓮𝙬𝙚𝓫𝒏𝓸𝓿𝓮𝒍.𝓬𝙤𝓶 As soon as he put the disc away, the entire base suddenly rumbled with explosions. The same went for the control center, and more than a dozen places exploded one after another. If there were any living people here, it would be very difficult for them to escape. Because the base was built in the middle of a mountain, the strong explosion had already caused the entire mountain to collapse. In the blink of an eye, the entire base was buried under the landslide. Lin Yi knew that this was Central's trap for him! It was not easy to take away the teleportation disc, but it was not as if he did not have the intention of keeping it as bait. The man in the grey hat understood Lin Yi very well, and knew that he'd be very interested in something that combined formations and technology, so he'd set the switch to the explosion in the disc. As long as Lin Yi touched the disc, the entire base would explode, and the disc would be destroyed in the explosion. Even if Lin Yi didn't die, he wouldn't be able to get it. It was a pity that the man didn't know that Lin Yi had the Jade space. He'd already kept the plate as bait before the explosion, and using the landslide on Lin Yi was a joke! In his spirit state, physical attacks like this were the least of Lin Yi's concerns. Even if the sky and earth were to fall apart, he wouldn't be affected at all as long as there was no damage to his spirit! After a while, Lin Yi emerged from the still-shaking mountain and floated in the air, sighing at the destroyed base. The explosion didn't do much damage to Lin Yi, but it buried the base completely. If there were any clues left, they'd all be gone with the explosion! The center ... Was really ruthless! Lin Yi shook his head helplessly after a while and returned to the Morning Star Mystic division school. He was prepared to say goodbye to everyone after dawn and make some arrangements before leaving.
