Since the ambush was most likely a smokescreen, Lin Yi made a bold guess-even if there were more similar situations, there wouldn't be too many of them. Besides, everyone had returned to their own bases, so it was unlikely that there would be too much of an impact. One guard Institute was enough to keep the situation under control, and Lin Yi didn't think he should be tied up here anymore. He had to find out the mastermind's true goal! On a Pavilion, Zheng Tianqing was playing with a Jade bottle in his hand. This was the last hallucinogenic agent that he had deliberately kept unused. There was not much difference between the effects of five and six portions. The impact that it had caused had far exceeded Zheng Tianqing's initial expectations. "Hehe, I'm a genius, after all. Shouldn't I give the last portion to Lin Yi's lackeys?" Zheng Tianqing was moved by the idea, but he still didn't dare to cause trouble for Lin Yi. There weren't any powerful experts among the five elements Chamber of Commerce's people this time. Even if they were poisoned with hallucinogens, they wouldn't be able to cause too much damage. They might even be subdued as soon as the hallucinogens acted up. Even if he could kill one or two of them, it wouldn't do Lin Yi any harm. If the whole thing was exposed, with Lin Yi's protective personality, he might just destroy the Zheng family. "Forget it, we can't kill Lin Yi, there's no point in dealing with those small fries! Let's go find Yu Ziqing and see what this guy is up to. I've already created such a good opportunity for him. If he still fails, then he's really a good-for-nothing!" Zheng Tianqing convinced himself to give up the idea, put away the Jade bottle, and left the pavilion. Although there were Northern Battlefront guards everywhere, Zheng Tianqing didn't care at all. Walking on the street, he was the young master Zheng Tianqing, an honored guest of the northernmost Island. The northern Battlefront guards wouldn't do anything to him. If Lin Yi had found him, he'd be suspicious, but he'd already left the area and was rushing to the northern beach. After thinking about it carefully, Lin Yi suddenly realized that if the sea beasts wanted to attack the northernmost Island, they would have to break the restriction first. There was no doubt that the loosening of the barrier was the work of the mastermind or his accomplices. Since they could loosen the barrier, they could most likely make the barrier ineffective, but they had not had time to complete it. With such a big scene today, it was probably time for them to reveal their true intentions. Lin Yi guessed that these guys 'real goal was to destroy the formation base of the northernmost Island! Every city guard post had its own area to guard. However, due to the continuous battles in the prosperous area, the North Garrison had been unusually mobilized, which led to the weakening of the guards in many places. It was the best time for them to take action. Lin Yi had asked li Zeyu before where the restriction array base of the northernmost Island was, and Li Zeyu didn't hide it. He gave a rough explanation, and although he didn't say everything, there must be one on each beach! However, the array bases on the beach were guarded by teams from the North Garrison, and they were protected by arrays above level Seven. No one could get close to them, so li Zeyu was not worried that it would be leaked. In fact, the people of the northernmost Island basically knew about the array bases on the beach. It was not a secret. It was because of this that Lin Yi rushed to the northern beach. If there was a place that the mastermind could destroy the most, it would be the base of the formation on the northern beach! Why did the northern border guard station have an underground passage leading to the beach? This was because the traitor had been planning to destroy this array base for a long time. Perhaps this was not the array base that had caused the restriction to loosen previously, but the first array base to be destroyed in the end would definitely be the array base on the North Beach! As it turned out, Lin Yi's intuition was quite accurate. When he arrived at the northern beach, the twenty-five people of the North Battlefront guards were all killed without even the alarm being sounded. And the array base that was usually protected by the combination of a concealment array, a defense array, and an attack array had been completely exposed. The level Seven formations were all broken, and the three of them were attacking the base of the formation. If it weren't for the fact that this was a top-tier formation from ancient times, they might have already succeeded by the time Lin Yi arrived! "Yu Ziqing, are you looking to die?" Lin Yi roared as a lightning arc flashed past and he appeared behind the three of them. Other than Yu Ziqing and aunty LAN, the other guy was a spirit beast in human form. Lin Yi's suspicions were right-there was something wrong with this guy! Yu Ziqing's heart skipped a beat when he heard Lin Yi's voice-he'd just broken through the protective array base after following the man's instructions, and Lin Yi, the God of plague, had arrived just as he started attacking! Now that Lin Yi had seen through their identity, if they couldn't overturn the northernmost Island, yeyue city would be regarded as the enemy of the northernmost Li family! "Wind Tiger, aunty LAN, kill him! We can't let this kid call for help!" Yu Ziqing screamed, not sure if he was afraid of Lin Yi or if he was afraid that Lin Yi would call people to disrupt the plan. Aunty LAN knew the seriousness of the situation and turned to kill Lin Yi without a second word. The wind Tiger, on the other hand, hesitated. After all, his main task was to destroy the base of the formation, not to kill Lin Yi. However, he remembered how he was chased by Lin Yi and exposed the underground tunnel, causing the spy in the northern border guards to be monitored. He was furious-if it wasn't for this guy, the formation base would've been destroyed already! With that thought in mind, Feng Hu didn't reject Yu Ziqing anymore. He roared and cooperated with aunty LAN to deal with Lin Yi. Yu Ziqing wanted to take the opportunity to escape, but he had no other choice now. He could only brace himself and continue to attack the array base. Unfortunately, his original infant stage strength was too weak, he could not shake the ancient array's array base at all! It would be an exaggeration to say that his little destructive power was better than nothing! Lin Yi hmphed coldly and pointed his finger. A few bolts of lightning as thick as water buckets poured down from the sky. The momentum was shocking, and no matter where one was on the northernmost Island, they would be able to see this scene clearly! Moreover, the power of these lightning bolts was even stronger than the lightning tribulation of the xuansheng stage. It was more than enough to deal with an opponent in the mountain opening stage. The lightning martial technique was one of the most powerful methods. As a signal, it should be conspicuous enough.
