When Lu Xian found Xiao Sheng, Xiao Sheng was already packing his things and preparing to depart. Upon hearing about the zombie outbreak that day and everyone being trapped underground, they had already decided to set out for rescue. Moreover, Qin Kewei and Yue Hengyi were on the missing list. These two were teammates who had fought alongside them before, and they couldn't stand by and do nothing. They had to go rescue them.
Cultivating a fifth-tier ability user in the laboratory was no easy feat. One evolution potion could create an evolver, but ten evolution potions could only create a second-tier ability user. Calculating carefully, a fifth-tier ability user was equivalent to consuming ten thousand evolution potions. Even gold of the same volume was not as precious.
When Xiao Sheng met Lu Xian and learned from him that Shen Feng was also trapped underground, he was immediately in a dilemma. If he didn't go to save Shen Feng and Shen Feng ended up dying accidentally, Shen Yu would never forgive him. However, it was also unreasonable not to go rescue Qin Kewei. This was clearly a difficult situation.
At this moment, Xiao Sheng saw Jin Zijue beside him and said earnestly to Jin Zijue, "Tomorrow, you go with Lu Xian to save Shen Feng. Good brother, I beg you to help me this time, and I will definitely repay you in the future!"
Jin Zijue was stunned when he heard this request. He wondered if he had misheard something. He and Shen Feng had quite a bit of a grudge. He had been threatened by Shen Feng several times in Rongcheng before. Now, Xiao Sheng was asking him to save Shen Feng. This seemed too strange.
"Hey, hey, hey, Xiao Sheng, what are you talking about? Shen Feng is your brother-in-law. If anyone is going to rescue him, it should be you. We can handle Qin Jie and the others, but you're asking me to save Shen Feng. Isn't that backward?" Jin Zijue said unhappily.
Xiao Sheng said earnestly, "You are more suitable than me to rescue Shen Feng. This matter is entrusted to you. I am not suitable for going underground, and only you can save Shen Feng, who is trapped. As for your past grievances, I believe this is a good opportunity to mend your relationship, and the misunderstanding should be resolved!"
Jin Zijue nodded helplessly and said, "It's only because you, Xiao Sheng, are asking me. Otherwise, I wouldn't help you with this. But I've made it clear, it's best if you find Shen Feng. If you can't find Shen Feng, it has nothing to do with me!"
Xiao Sheng nodded seriously and said, "Of course!"
Lu Xian quietly pulled Xiao Sheng aside and asked doubtfully, "Shouldn't you be the one to rescue the City Lord yourself? Why are you letting someone else go?"
Xiao Sheng looked around and whispered to Lu Xian, "My ability is fire, and it's super high-temperature fire! The oxygen consumption underground must be particularly severe. Among our four fifth-tier ability users, only Jin Zijue's ability is suitable for going into the tunnel. I'm letting him go with you entirely for Shen Feng's sake. Conversely, if I go to save Shen Feng myself, it would be of little use!"
Xiao Sheng had made his decision after careful consideration. No one was more suitable for rescue than Jin Zijue. If he had to find someone to help, Jin Zijue would be the one to find. The only thing to worry about was whether Jin Zijue would agree.
Lu Xian suddenly understood. So, Xiao Sheng's ability would not be very effective underground. Instead of that, it was better to let the more suitable Jin Zijue go with them, which would also increase the chances of rescuing the City Lord.
The next morning, Lu Xian, Guo Pinming, and Jin Zijue headed straight for the cave entrance twenty kilometers away. He knew the area he had explored in the past few days, and Shen Feng would definitely have been active in this vicinity. The best course of action now was to search nearby and then gradually expand the search area.
Lu Xian looked at the detector on his body and sighed helplessly, tossing the detector aside. He knew it wasn't the time to use the detector; the most urgent task was to save people.
Guo Pinming drove the truck to the destination. When they reached the foot of the mountain, he stopped the car, carried a large bundle of steel bars from the truck bed, and followed Lu Xian up the mountain.
When Lu Xian saw Guo Pinming carrying a large bundle of steel bars, he was confused and quickly asked, "We're going to rescue people, not kill them. Why are you carrying so many steel bars? That's at least ten tons. This is such a strenuous item, throw it away quickly!"
Guo Pinming said earnestly, "I heard the whole story from you. In my opinion, the City Lord couldn't escape smoothly because the earth-digging zombies pushed down rocks and soil, blocking the entrance. In that case, to ensure our rear is not cut off, we must reinforce the entrance so that it cannot be easily destroyed. These steel bars can serve that purpose."
Lu Xian then understood why Guo Pinming had brought so many steel bars. It turned out they were to ensure the exit wouldn't be blocked. It seemed Guo Pinming was also a person full of stratagems, considering issues comprehensively and meticulously.
Lu Xian led the group to a cave entrance near the exploration area. All the previously explored caves were blocked, so they could only descend from the nearest one. Guo Pinming used his ability to manipulate the steel bars into a cylindrical cage. This cage perfectly fit the tunnel walls, preventing the passage from being easily blocked unless this steel cage was bitten open.
Jin Zijue carried a large backpack filled with plenty of food and water. He knew what was most important when going underground. It wasn't guns and ammunition, nor high-tech equipment, but supplies that could last a long time. Both drinking water and food were extremely valuable.
The three quickly entered the cave. Jin Zijue casually took out a light bulb, and with a flash of electricity from his finger, the bulb lit up. He didn't need to carry a flashlight; he only needed to bring a light bulb. As long as he had a light bulb, he could generate electricity himself, and advancing in the underground tunnels would not be hindered by visibility issues.
At this moment, Lu Xian finally understood why Jin Zijue's ability was the most suitable for going underground, as Xiao Sheng had said. By bringing a light bulb to walk underground, they would not be bothered by the darkness. This ability was indeed the most useful for going underground.
After the three had walked for a while, the ground suddenly trembled, and countless zombies rushed towards them. Even at this point, the zombies had not stopped their rampage and were still seeking humans to attack.
Guo Pinming quickly stepped forward. He still had a large iron ingot on his back, which was his weapon. Then, he unleashed his ability, and countless iron spikes shot out from the iron ingot. In just a blink of an eye, the zombies in the cave were pierced by the spikes. The spikes, as if alive, extended towards the depths of the cave, killing all the zombies in this section of the passage.
Lu Xian closed his eyes and unleashed his ability. The heat distribution in the tunnel was all presented in his mind. Within a one-kilometer radius, there were no more zombies.
"There are no zombies nearby, let's keep moving!" Lu Xian said quickly.
Lu Xian now understood the importance of his task. He had to detect the number of zombies in advance. Once zombies appeared, he had to give an early warning. Just now, there were only a few hundred zombies here, and Guo Pinming could deal with them instantly. However, if there were tens of thousands of zombies, it would not be something that could be resolved in a short time. If they were entangled by zombies, let alone rescuing people, even self-preservation would be very difficult.
Lu Xian led the group through the underground for a long distance before discovering familiar markings. These were markings left by Shen Feng in the tunnel to prevent them from getting lost, meaning the three had reached the area they had explored before. Currently, there were still many zombie corpses in this area. These corpses were killed by Chu Chaoyan using her ability. There were also many footprints on the ground, clearly left by zombies. If it were just Shen Feng and Chu Chaoyan, they wouldn't have left so many messy footprints.
Lu Xian continued forward and suddenly discovered a black backpack on the ground. At this moment, he remembered and quickly said, "Yes, it was here that the City Lord dropped his backpack and carried me forward. I know the way, follow me quickly!"
Lu Xian recalled Shen Feng's route forward. Now, as long as they followed Shen Feng's direction, they would find him. He immediately became excited, thinking that this crisis could be resolved!
"Look over here, there are a few bags of salt on the ground!" After walking for several kilometers, Jin Zijue, with sharp eyes, saw salt on the ground and quickly reminded them.
Lu Xian looked down. This salt was brought by Chu Chaoyan, which meant Shen Feng had come this way. But why would he throw away the salt?
Just then, Guo Pinming pointed to the distance and said, "Look over here, there are so many corpses on the ground, all of them died from external injuries. There was a battle here!"
Lu Xian and Jin Zijue quickly went forward to observe, only to find many corpses lying askew in the tunnel. These corpses filled the entire tunnel, leaving almost no room to step. The original yellow earth had turned dark red, stained by the zombies' blood. It was imaginable how desperately Shen Feng had fought to leave this place.
Guo Pinming lowered his head and carefully observed the zombie corpses, saying, "The wounds on these are sword wounds, as well as damage caused by dagger stabs. It seems the City Lord and Miss Chu are safe, and they fought their way out from here!"
Jin Zijue couldn't help but laugh and shake his head upon hearing this analysis, saying, "I didn't expect that even in such a situation, Shen Feng could carve out a path of blood. It's truly admirable."
Suddenly, Lu Xian sensed a heat reaction in the distance of the tunnel, and it was rapidly increasing. His expression changed drastically, and he said, "Let's go quickly, there's a heat reaction of zombies ahead, and the number of these zombies is very large."
Lu Xian instinctively wanted to leave this place, but Jin Zijue spoke up, "What are you afraid of? I am a fifth-tier ability user. With me here, can't I protect you two? No matter how many zombies there are, I will kill them all. Shen Feng could carve out a path, so why can't I?"
Since Jin Zijue had said so, Lu Xian and Guo Pinming could only stand there and wait to watch Jin Zijue's performance. More and more zombies appeared in the depths of the tunnel, stepping on their companions' corpses as they charged towards Jin Zijue. Jin Zijue held a light bulb in one hand and pointed forward with the other, his eyes fixed on the depths of the cave, standing his ground without fear.
Seeing the number of zombies increasing, Jin Zijue roared, "Green Snake Dance!"
In an instant, countless currents were emitted from Jin Zijue's hand. The charging zombies were hit by the currents and instantly fell to the ground. The current, upon contact with the zombies, would paralyze their entire bodies. This was not the most important thing. The reason Jin Zijue was confident was that the lightning he released could destroy the zombies' brains in an instant. With the brain destroyed, the zombies could not live.
"Crackling..." Electric arcs leaped through the air, the sound exceptionally crisp. After this move by Jin Zijue, hundreds of zombies were instantly eliminated.
Unfortunately, after the zombies in front were killed, more zombies continued to charge forward, showing no fear due to Jin Zijue's move. Jin Zijue could only wait for the zombies to get closer before releasing currents again, killing these foolish zombies.
Lu Xian had been using his ability to observe the situation in the tunnel. Although Jin Zijue effortlessly killed thousands of zombies, in his observation, the number of zombies not only did not decrease but was increasing. Numerous zombies were charging forward fearlessly.
Suddenly, Lu Xian's expression changed, "Not good, there are zombies appearing in the tunnel behind us, and they are rushing towards us!"
Jin Zijue frowned, surprised that the number of zombies was increasing. Why were these zombies still charging forward? Weren't these zombies afraid of death?
"Let's retreat quickly, Mr. Jin, you cover our retreat, and I'll clear the path ahead!" Guo Pinming also couldn't remain calm. Seeing that Jin Zijue had killed thousands of zombies, but the zombies were still appearing endlessly, it was clear that they couldn't be killed in a short time. No one knew how many more zombies would charge forward. For now, they could only retreat temporarily.
Jin Zijue did not object at this time. After the battle, he suddenly realized that he had been too overconfident. He could kill tens of thousands of zombies, and he could repel all the charging zombies, but the number of zombies was not just ten thousand. The zombies in any direction from Yanjing numbered in the tens of millions. Such a large number of zombies was not something he could handle.
"Hurry up, don't get surrounded by these zombies!" Lu Xian also urged them.
