After only excavating thirty-four pieces of meteorite iron, the energy pickaxe in Ye Yu's hand had already run out of energy, and Ye Yu's points were not enough to buy energy bars, so he could only leave this mine first, return to the main world to complete the task first, and then continue to mine meteorite after obtaining points.

Leaving the mine, Ye Yu contacted Zhao Tiedan and asked him what the situation was on which side, Zhao Tiedan said that he had excavated a lot of meteorite iron ore, and he was about to reach the number of a group, and he didn't have many points left, and it was estimated that he could only dig a group of meteorite iron ore in the end, and then he had to leave the mine to do tasks to obtain points.

"Where do we meet from the lunar portal?" After Ye Yu finished speaking, he walked according to the position displayed by the coordinates, and the system placed the coordinate display for him, through the position displayed on the coordinates, he could easily find the lunar portal.

Returning to the lunar portal, Ye Yujing waited for Zhao Tiedan to come back, and in the process of waiting, he found that there were several figures in front of him, and those figures were constantly advancing towards this side, getting closer and closer to the lunar portal.

Feeling that something was wrong, Ye Yu took out the Transformation God of War, installed the bullets with extreme speed, and prepared to duel with the several figures in front of him who were constantly advancing.

Ahead of them were several robots who saw the lunar portal and thought it was an exit from the desolate land, so they walked towards the portal to get out of this terrible place.

After determining that it was the enemy, Ye Yu pulled the trigger to fire bullets and shot those robots in the head, causing them to suffer an unprecedented blow.

"There are unknown intruders, shoot back!" The leading robot shouted, and those robots around it immediately raised their guns to strafe Ye Yu in front of them.

It had long been known that these robots would strafe themselves, so Ye Yu hid behind the portal in advance to dodge.

The bullet hit the door frame of the lunar portal, Ye Yu was waiting for those robots to stop shooting, as long as they stopped shooting, then Ye Yu had a chance to solve them all.

Soon the robots stopped firing, and they slowly pushed forward, trying to know if the person who attacked them was dead.

Thinking that now was a good opportunity to attack, Ye Yu quickly pulled the trigger and used the Transforming God of War to strafe those robots and eliminate a few of them.

After eliminating those robots, Ye Yu squatted down, took a deep breath, and his beating heart gradually calmed down.

"Hey, what's going on?" Zhao Tiedan's voice came from his ears, Ye Yu felt something on his shoulder, he turned around with lightning speed, and was just about to pull the trigger of the deformed god of war, when he suddenly stopped.

There was Zhao Tiedan standing beside him, this guy didn't know when he came to his side, Ye Yu said to him angrily: "Can you not stand behind me like a ghost, don't you know that people are scary and scared to death?" ”

"Uh, I'm sorry." Zhao Tiedan looked very sorry and asked Ye Yu what he was doing.

Ye Yu told Zhao Tiedan that he had encountered a few robots just now, and he had fought with those robots, and he had already eliminated those robots just now.

"Let's go, go back and finish the task first." After Zhao Tiedan finished speaking, Ye Yu nodded, and the two of them entered the lunar portal and returned to the main world of Aoba City.

Running home at a very fast speed, Ye Yu returned home and opened the furnace and put the meteorite ore in it, but the furnace didn't have any reaction.

"What's the situation?" Ye Yu saw that the furnace did not react, and slapped the furnace vigorously, thinking that there was something wrong with the furnace.

There was coal in the furnace, but the meteorite ore didn't have any refining progress at all, and the furnace didn't have the light that should be on when refining ore or baking food.

"Ding, tell the host, refining meteorite iron ore requires an energy furnace to refine, and energy ore is needed to be used as fuel."

The words of the system spread through Ye Yu's mind, Ye Yu's face was extremely ugly, and there was an expression that was very similar to his current expression, that is, Thomas-style little black face.

Spreading his hands, Zhao Tiedan said to Ye Yu: "If the ordinary furnace could refine meteorite iron ore, I would have been digging on the moon a long time ago, the energy of the energy pickaxe is exhausted, meteorite iron ore needs a special furnace and fuel to be refined, and special furnaces and fuel need to be exchanged in the system's points mall." ”

Clenched his fists, Ye Yu wanted to pull out the system in his heart and beat it even harder, he thought that after refining the meteorite iron ore, he could save a lot of things by using the meteorite iron to make a pickaxe to mine on the moon, and he didn't have to take risks to do tasks for the time being.

After waiting for enough ores, make weapons, directly attack the city of Slashing Spirit, destroy those robots and the three mechas, and the task will be completed naturally, but now you still have to do the task to earn points, Ye Yu wants to exploit the loopholes in the system, it is too difficult.

Seeing that the sky was about to get dark, Ye Yu and Zhao Tiedan began to discuss the plan to sneak into the Slashing Spirit City, at this time Nuo Nuo walked in from the outside, and heard the two of them say that they were going to sneak into the Slaying Spirit City tonight, saying that they would also go with them.

"Hey, I heard that something happened in the Overworld, and I came to help you, how about it? Am I funny enough? This unpleasant voice came into the ears of Ye Yu, Zhao Tiedan, and Nuo Nuo, who was wearing a black robe, and stood at the door.

Even if he was wearing a big black robe, so people couldn't see his appearance, but no matter how hoarse his voice was, they could hear it.

"You called him?" Ye Yu asked Nuo Nuo, who shook his head and said that he didn't call him here.

He sat opposite Ye Yu unceremoniously at all, and smiled sheepishly: "Don't have this kind of expression, Spirit Slaying City is the predecessor of the Evil Spirit Legion, with me helping you, it will be very convenient for you to sneak into Spirit Slaying City." ”

If he didn't remind him, Ye Yu really forgot that Slashing Spirit City was the headquarters he was in charge of before, and he did know a lot about Slashing Spirit City.

Ye Yu nodded, and said to him: "Okay, tonight's action is yours, after this matter is over, if you have made outstanding contributions, then you don't have to wear a black robe to hide in Aoba City to see us in the future." ”

"Is that true?" He asked Ye Yu, Ye Yu nodded, saying that he never regretted what he said.

With a snap of his fingers, he smiled and said, "It's a deal, let's start discussing the plan now!" ”

The four of them sat around the table, discussing how to infiltrate the Slashing Spirit City, the current defense of the Slaying Spirit City was several times tighter than before, and it was very difficult to sneak in.

"Breaking into the Spirit Slashing City from underground, there is a secret passage near that city, and I am the only one who knows about that secret passage, and the person who built the secret passage has already been solved after the construction of the secret passage."

After he finished speaking, Ye Yu and the other two all stared at him with strange eyes.

Being stared at by others, he hurriedly said to them: "Don't look at me like this, it was the secret passage I built before, he thinks that the secret passage will come in handy sooner or later, as for whether it is used for strategy or escape, it depends on the situation." ”

The sky was completely dark, Ye Yu and the others rode Xiaoying and the phoenix to the vicinity of the secret passage that he said, and they prayed in their hearts that the secret passage still existed.

The last time Ye Yu led the team to attack the Slashing Spirit City, the three mecha in the city had a thorough understanding of the Slaying Spirit City, and they didn't let go of any of them, they wanted to use the Slaying Spirit City as a base, so they naturally had to understand this base thoroughly first.

Arriving at the destination, Xiaoying and Phoenix landed according to the location Ye Yu and Nuno said, Ye Yu and they still have some way to go from Slashing Spirit City, they can't get too close to Slashing Spirit City, a little closer may be discovered by the guards of the robot.

The robots that are guarded don't feel tired, they can be guarded 24 hours a day, they can see clearly in the night, and if they find something they can, they will attack without saying a word.

Crawling forward slowly, Ye Yu and the others were afraid that they would be discovered by those sharp-eyed robots, and once they were discovered, then they would have to find another time to enter the city.

HIM was leading the way for the others, and he really hated why he had said that there was a secret passage before, but now it was better to be this kind of deadly pioneer.

Climbing to the location of the secret passage, he dug the soil on the ground with his hands, and after digging it out, he said to Ye Yu and the others behind him: "Just jump down, there is a big pool below, you won't fall to your death if you jump." ”

"Then what are you talking about, hurry up and jump!" Ye Yu whispered to him, his tone was a little heavy, and after listening to his words, he was very speechless in his heart.

The reason why he didn't want to jump first was because he was worried that this secret passage had already been discovered by the mecha, and if the secret passage had been discovered by the mecha a long time ago, then the mecha was likely to evacuate the water below, and if he jumped down, there was no water below, and the height of dozens of squares would definitely be killed.

"What are you hesitating about?" Ye Yu saw that he didn't jump down quickly, and asked anxiously.

To make way for Ye Yu, he whispered to him: "Otherwise, you should jump first, I'm afraid that this secret passage has been discovered, and if it is discovered by the mecha, I'm afraid that if I jump in, I may die." ”

After listening to the reason why he refused to jump first, Ye Yu just wanted to say that he would kill him, the turtle grandson.

"Get out of the way!" After Ye Yu finished speaking, he quickly climbed to the entrance of the secret passage and jumped down without hesitation.

Falling down suddenly, this feeling of falling made Ye Yu feel a little excited, he fell into a large pool, and his health did not decrease by half a bit.

Nuo Nuo and Zhao Tiedan fell one after another, only him had not fallen, Zhao Tiedan shouted upward: "him, why haven't you come down yet?" ”

He is waiting for anyone to speak in the secret passage, if no one speaks in the passage, it proves that the mecha has discovered this secret passage and drained the water in the pool, Ye Yu and they are likely to have fallen to their deaths.

Now hearing Zhao Tiedan's shout, he was finally able to rest assured, he jumped into the secret passage without hesitation, successfully fell into the pool, and arrived safely inside the passage.

"Where does this safe passage lead to Spirit Slaying City?" Ye Yu asked him, and he told him that he was leading to the main hall of the headquarters of the Evil Spirit Legion.

"We can't go straight ahead, we have to dig from somewhere else and change the position of the exit, if we go directly, it will be easy to run into those three mechas."

After Ye Yu finished speaking, the others nodded, agreeing very much with what he said.

The four men changed direction and dug more than thirty blocks before stopping, then digging upwards and then returning to the ground with cobblestone.

He sighed, looking rather helpless: "I hope our exit will be a better place, and we won't dig up and run into those iron lumps." ”

"I've found that you're always saying so many useless words, here you go, it's your turn to dig up." Zhao Tiedan threw the diamond pickaxe to him, and it is better to use the diamond pickaxe with enchantment efficiency to dig cobblestone.

He stared at the diamond pickaxe floating on the ground, and looked cheap: "I have done you so much, can't you exempt me from such labor?" ”。

Seeing the unkindness in the eyes of the others, he shook his head and kept muttering: "It's not a good fate, I met so many ungrateful friends, if it weren't for me, how could you sneak into the Spirit Slashing City so easily, there is no good reward for your kindness." ”

Picking up the diamond pickaxe, he obediently dug the cobblestone above, and every time he dug to the apex of the range, Ye Yu and the others would put cobblestone under their feet.
