As soon as Shen Feng heard Chu Chaoyan's suggestion, he froze in place, because at this moment he suddenly thought of something. It seemed that the method used by the Zombie King to control zombies was ultrasonic waves, and the detector he carried also emitted ultrasonic waves. Instrument, in this way, once the zombies can hear the ultrasonic waves emitted by the instrument, doesn't it mean that everyone's position is exposed, and it is impossible to avoid the zombies as long as they carry the detector?
Chu Chaoyan felt strange, why did Shen Feng stop suddenly at this time? Didn't he want to compete with the zombies for speed? Could it be that Shen Feng was stupid?
Shen Feng put Chu Chaoyan down and said anxiously: "Throw away all the detectors, hurry up, otherwise we will never be able to escape smoothly!"
Shen Feng and Chu Chaoyan put down the detector, and then cut the detector in half with a sword. The detector was immediately disabled and could no longer emit ultrasonic waves.
"Damn it, why did I just think of this now? If I could have discovered this problem before, wouldn't I have never encountered this danger at all?" Shen Feng blamed himself very much, because he knew it a long time ago. The Corpse King can emit ultrasonic waves, but he made a mistake on this issue.
Chu Chaoyan quickly comforted: "It's okay, haven't we encountered zombies yet? Let's leave from the other cave entrances. Fortunately, we have killed the zombies in these tunnels. Will there be any danger now? ."
Shen Feng was silent for a moment, then suddenly turned off his flashlight and said to Chu Chaoyan: "We must save supplies now. The flashlight can only be turned on once. We can't see the road without light, let alone find the road in the tunnel."
Shen Feng then carried Chu Chaoyan forward in the tunnel, but only then did he realize that all the exits around him were blocked by zombies. No matter which exit Shen Feng went to, he could only find that they were blocked by earth and rocks. The exit seemed to have lost all escape routes in an instant.
Chu Chaoyan guessed: "The Corpse King must have discovered the missing traces of the two of us, so he simply blocked all the surrounding cave entrances and planned to catch turtles in an urn!"
Shen Feng stopped running and sighed: "If it is what you said, it would be too troublesome. We have never been to the further tunnels and have no understanding of the terrain. It is very likely that we will encounter zombies. Once we are entangled by zombies, Stay, we will definitely die!"
"Damn zombies, so despicable!" Chu Chaoyan couldn't help but cursed. The hateful zombies were so despicable. The mission to explore the underground was a pure trap, and the two of them were now trapped underground. If they couldn't leave quickly, , I am afraid that my life will be in danger.
Shen Feng opened Chu Chaoyan's backpack. There were more than twenty compressed biscuits in her backpack, but there was only one bottle of drinking water left, and only five dry batteries left. With such a small amount of supplies, it was just They can only last two days underground, and during this period, the two of them face the threat of zombies appearing at any time.
In addition to the necessary supplies, there were several bags of salt and some notebooks in the backpack. Shen Feng thought about it and threw the salt to the ground.
Seeing this scene, Chu Chaoyan quickly stopped him and said, "Don't throw it away. I rely on these salts to use my powers. If you throw them away, what kind of powers will I use?"
Shen Feng shook his head helplessly and said: "We don't have much drinking water, and your superpower can only create chlorine gas from water. If you use your superpower, you will definitely consume drinking water, and we will die of thirst by then. Don't worry, I will protect you now and won't let you get hurt."
When Chu Chaoyan heard this explanation, she had no choice but to put down the salt. She was thinking at this moment that it would be great if the battle took place at the beach. With her own superpower, she would be able to summon a piece of chlorine gas with just a wave of her hand. No matter what Any number of enemies can be destroyed. But what Shen Feng said makes sense. If you need to consume drinking water, you will have no room to use your own abilities.
"Okay, it's all up to you!" Chu Chaoyan said helplessly.
The reason why table salt is needed by humans is that humans need to supplement sodium ions from table salt, but the supplement of sodium ions is also within a certain range. Once sodium ions are taken in excessively, it can easily lead to hypertension-type diseases, and Ingesting a large amount of sodium ions in a short period of time will cause the body's osmotic pressure to increase, causing the body to become extremely thirsty and need to drink water.
As for the water left after Chu Chaoyan created the poisonous gas, it is all filled with sodium ions. Anyone who drinks it will become thirsty and is completely useless.
Therefore, Shen Feng threw away the salt after weighing it. This thing is not important. Human beings will develop diseases only if they do not consume salt for a long time. There will be no problem if they do not consume salt for a short period of time. Instead of adding weight to the backpack, it is better to It's better to throw it away and then increase your speed.
Shen Feng and Chu Chaoyan sat in the tunnel and began to rest. Shen Feng planned to go to the unknown tunnel in the distance to find an exit. It was impossible for all the exits to be blocked. There must be a hole in the distance that could be left. The only problem was It is easy to encounter zombies on the way to these exits. Once surrounded by zombies, it will be difficult to escape.
Chu Chaoyan was more optimistic. She believed that Lu Xian would definitely come to the rescue with reinforcements. As long as he found that she and Shen Feng had not appeared, he would definitely return to Yanjing to ask for help. In this way, as long as she could hold on until the reinforcements If you appear, you will be saved.
Shen Feng touched the two long swords at his waist. He knew that these were the only things he could rely on now. As long as the swords were still in his hands, he would not be killed by zombies.
Shen Feng and Chu Chaoyan did not rest for too long. Suddenly there was a slight vibration on the ground. The two of them immediately became vigilant. Roaring sounds came from both ends of the tunnel. Along with the roaring sound, there were rapid footsteps. Zombies appeared at both ends of the tunnel. These zombies moved quickly and brought up countless dust in the tunnel.
Shen Feng quickly said to Chu Chaoyan: "Come on, let me carry you and bring your backpack!"
Chu Chaoyan took out two daggers from his body and said seriously: "I can fight too."
"I don't want to fight, I want to take you to escape. Fighting with these zombies will only waste your energy in vain. Come up quickly!" Shen Feng said.
Shen Feng bent down in front of Chu Chaoyan. Chu Chaoyan quickly lay on Shen Feng's back and clamped his legs around Shen Feng's waist. In this way, Chu Chaoyan could stay firmly on Shen Feng's back. On his back, at this moment, Shen Feng chose a direction and rushed out. He slashed with both swords and finally cut a bloody path.
Shen Feng wanted to increase his speed to the extreme, but the tunnel was too narrow. As long as he moved forward, he would inevitably encounter zombies. He couldn't really increase his speed. He could only advance while slashing until he was blocked by zombies. authentic.
Fortunately, after Shen Feng became a fourth-level superpower, he could not use up all his strength, so Shen Feng did not feel exhausted in a short period of time, and he also carried Chu Chaoyan on his back and headed towards the unfamiliar tunnel. Since All the tunnels he is familiar with are blocked, so he can only head towards the unknown direction. If God bless him, he will definitely be able to find a new exit.
With this idea in mind, Shen Feng moved forward with difficulty. The zombies in the tunnel seemed to appear endlessly. He killed one and then ten more rushed up. Under such circumstances, Shen Feng could only cheer up and bear the belt of zombies. There was huge pressure to move forward, but fortunately Chu Chaoyan was able to help Shen Feng share part of the pressure, so that Shen Feng could move forward.
Unknowingly, Shen Feng killed thousands of zombies, and at this moment, he was already feeling tired. In the narrow tunnel, zombies lined up to rush up, seemingly lining up to die, but in fact, these zombies were just consuming. No matter how many of Shen Feng's physical cannon fodder die, the Corpse King will never feel sorry for him.
The hard work paid off. Shen Feng saw a hole leading to the ground in the distance. After a closer look, the hole was not blocked. This showed that the hope of leaving the underground appeared. As long as he could leave from here, then he would Can survive.
"Chaoyan, hold on, we can survive as long as we rush over!" Shen Feng said quickly to Chu Chaoyan.
Chu Chaoyan lay on Shen Feng's back and kept swinging the dagger to kill the zombies in front. She was relieved at this time and echoed: "There is only a dozen meters away. As long as we rush over, we will be safe. I I will persevere.”
Now that the opportunity to leave the tunnel appears in front of them, Shen Feng and Chu Chaoyan have to brace themselves for it. They are only one step away from escaping. The opportunity is in their own hands. If this kick misses the mark, If so, wouldn’t it be regrettable?
However, at this moment, the tunnel began to shake. Shen Feng and the surrounding zombies were unable to stand steadily. The surrounding earth and stone walls were also shaking, and seemed to collapse at any time.
"Could it be an earthquake?" Chu Chaoyan asked hurriedly.
Before Shen Feng could answer, the ground began to collapse instantly. This section of the tunnel fell downwards. Shen Feng and countless zombies also fell down. No one expected that there was still space below, and Shen Feng finally did not You can leave the underground through a newly found exit.
"Boom..." In the collapse of the ground, Shen Feng and Chu Chaoyan fell down, along with many zombies. In the darkness, Chu Chaoyan's flashlight stopped shining. At this point, the entire tunnel was Plunged into darkness.
…………
After Lu Xian left the tunnel, no one appeared when he was waiting, and Shen Feng was not seen on the right. He couldn't help but go to the cave entrances that he had explored, but found that all of them were blocked. , he suddenly panicked. It seemed that the city lord and Chu Chaoyan were trapped below. The entrance to the cave was now blocked. He wanted to rescue the two but had no idea where they were now.
"No, I have to go back and ask for help. My own strength is still too weak. Only by asking for help can I rescue the city lord!" Lu Xian thought about it and there was only one way to ask for help. I guess whether it was Guo Pinming or Yang Chang, both of them were the same. People with superpowers, with their help, you will have more confidence.
Lu Xian figured this out and ran quickly in the direction of Yanjing. However, before leaving, he also placed his backpack outside the entrance of a cave. If the city lord digs out the earth and rocks from the ground, he can get some Some supplies.
After returning to Yanjing, Lu Xian quickly found Yang Chang and Guo Pinming and explained what happened today. However, it was already approaching dusk and it would be dark soon. It was not a good time to set out for rescue now. More importantly, One thing is that they can't leave their posts without permission. Before Shen Feng left, he also told the two of them to guard the city wall.
However, Guo Pinming had an idea at this time. He said seriously to Lu Xian: "Go and contact Xiao Sheng from the Superpower Management Bureau now. He is the boyfriend of the city lord's sister. He will definitely not ignore death now. You Let him help, and I will set off together tomorrow morning, leaving the city wall to Yang Chang!"
Yang Chang originally wanted to rescue Shen Feng. After all, he was promoted by Shen Feng. Now it is definitely appropriate to search and rescue Shen Feng. But he can only stay in Yanjing. If he leaves, The five thousand men under his command completely lost control, and the task of rescuing people could only be left to Guo Pinming.
Yang Chang took a deep look at Guo Pinming and said seriously: "Old Guo, everything is left to you. The city lord must return safely. Otherwise, how can we still have the face to go back to see the deputy city lord?"
Guo Pinming nodded seriously. He understood what Yang Chang meant. He thought about how he disobeyed the city lord's orders and attacked without permission, which eventually led to the annihilation of a thousand soldiers. In the end, Shen Feng also ignored the previous suspicion and asked himself to go to the south to buy medicine and use the task Come and atone for your sins.
And now he also needs to repay Shen Feng. He has been taken care of by Shen Feng since he was in Jiangyang. Not repaying this kind of kindness would be ungrateful. And Yang Chang cannot leave Yanjing, so the rescue mission is left to him. On people!
Lu Xian didn't have time to say anything, so he turned around and went to look for Xiao Sheng. Now the only one who can participate in the rescue is Xiao Sheng. He is a genius of the Superpower Management Bureau and has many friends. If he is willing to help now, he will definitely be able to make full use of it. Of great effect. This chapter has been completed!
