Yun Yun followed Xi Ran's order and after arriving, she began to attack the alloy wall like crazy. Yun Yun's attribute, which was not lower than Xi Ran, fell on the alloy wall that had just been upgraded to level 4, and the durability on the alloy wall suddenly jumped. It was obvious that the level 4 alloy wall was really a bit reluctant to resist Yun Yun's attack.

However, there are a lot of goblin tinkers behind the alloy wall to repair it. Although the durability is still very violent, Yun Yun cannot get it for a while. And the three elves also planned to continue upgrading the alloy wall just when the resources are in place. If Yun Yun continues to do so, it will be more and more troublesome. However, looking at the beating durability, the three elves in it are so worried. Seeing that Yun Yun came alone, he thought to himself, "If there is only one, there should be no problem with upgrading to level 5 alloy wall. Now this level 4 alloy wall is not very reliable. The resources to upgrade to level 5 alloy wall will be enough after about 20 seconds. Let's stabilize the current situation first..."

So, these elves began to use frozen armor. Due to the effect of frozen armor, the frequency of the durability of the alloy wall quickly stabilized, and finally recovered and stopped moving. Seeing that the opponent finally used frozen armor, Yun Yun also knew that the situation Xi Ran planned to happen, and did not stop the attack because the effect of frozen armor was still there. Although she could not cause damage, she still attacked hard. What she wanted was to bring huge psychological pressure to these elves and let them use all the frozen armor.

Time for a frozen armor passed, the effect of the frozen armor disappeared, and the durability of the alloy wall was falling down quickly again. Moreover, it was almost destroyed, which made the three elves feel shocked. The speed was too fast. They could not understand that Yun Yun suddenly seemed to be slightly improving. Although it was not 1 second, 7 times, it was also fast. The attack speed had steadily surpassed Xi Ran. I guess Xi Ran, the master of Yun Yun, could not explain what this situation was. Perhaps only Yun Yun herself knew. But she didn't say it, and Xi Ran didn't ask.

"Hurry, add frozen armor to the city wall. This level 4 alloy wall is not reliable. You have to wait until you upgrade to the level 5 alloy wall!" The elf was really panicked by Yun Yun's fierce attack. The elf who had released the frozen armor asked his companions to quickly add frozen armor to the alloy wall.

The other elves did as well. In this way, two frozen armors were continuously frozen, allowing the alloy wall to spend 20 seconds. The upgrade resources were enough. The elf who belonged to the alloy wall quickly made the final upgrade for the alloy wall. There was no way, Yun Yun's attack was really terrifying. Although they hired the elves of the God Son of God to destroy most of the goblin tinkerers in order to free up the population, the number of them was born was quite large. 9 goblin tinkerers, each of which could repair 5% of the durability per second, and 45% of the durability in one second, but it was still too late, because Yun Yun's attack speed broke through again at this time, and 7 attacks in 1 second were achieved. This was a speed that even Xi Ran could not reach. Yun Yun reached it first. If Xi Ran knew about it, he would definitely be surprised.

Yun Yun can cause nearly 60% damage to the alloy wall every second. If it weren't for the hard work of the tinkerer to maintain the durability, it would explode in less than two seconds. Even if it was repaired, it could only last for 3 seconds at most. When the 4th second was reached, it would still explode, and the upgrade time would take 5 seconds. In this case, the elves were helpless, and the elf who proposed the transaction with Xi Ran had already vaguely guessed what Xi Ran thought. The elf smiled bitterly and thought to himself, "Is this a disaster for raising demons? Unexpectedly, they have become so powerful... a mistake..." At this moment, he really regretted it, regretted being used in anger, which led to such losses. He regretted his self-confidence. He destroyed Xi Ran's surveillance before the alloy wall was upgraded to level 5. Anyway, he felt all kinds of regrets in his heart.

However, there is no regret medicine in this world. In order to prevent the alloy wall from being destroyed before the upgrade is completed, he can only bless the last frozen armor of the three of them on the alloy wall. With the effect of frozen armor, the upgrade of the alloy wall was successfully completed. However, the last elf who released the frozen armor, that is, the elf who was discussing the transaction with Xi Ran, had only bitterness on his face. "Let's withdraw..." At this time, he spoke to his two companions. After hearing his words, his two companions showed a look of shock on their faces. The excitement caused by the completion of the upgrade of the alloy wall also disappeared without a trace.

"Why? Haven't we successfully upgraded now? There should be no problem with the level 5 alloy wall blocking this ghost wolf. Look at the trolls are all struggling there. Is it necessary? There should be no danger." One of the elves said. They are not as smart as this guy who proposed to trade with Xi Ran, and they have not yet seen what Xi Ran thought.

"No, if I guess correctly, in less than 5 seconds, the troll will appear here. How long do you think this level 5 alloy wall can last under the double attack of the troll and the ghost wolf? Of course, under normal circumstances, it can still maintain durability with a ground tinker repair, but don't forget that those four guys' walls reached level 5 alloy walls before us, but what about them now? They have become betrayal dogs? Now that I have said this, I think I have finished my best. Anyway, the choice is in your hands. Do you like to leave or not, I will leave first." If you continue talking here, he will feel that this is a waste of time. I ignore the reactions of the two companions and flew out directly.

After hearing the words of the elf who had already jumped out, the other two were stunned. However, if they could survive in the reincarnation space and become lone walkers, there would not be too stupid among these people. After reminding this elf, they thought for a while and found that the situation was almost the same as what this guy said. After gritting their teeth, they also jumped out. Although they knew that going out would be equivalent to giving up the long-running base, they still went out and continued to stay. It was a behavior of seeking death.

Xi Ran also received the message sent by Yun Yun through the soul contract, and learned that the frozen armor of the three elves had been used. He was about to start teleportation, but his hand holding the teleportation scroll suddenly stopped. On the safe side, Xi Ran decided to look at the situation inside to avoid a waste of time. The Vision Technique was activated, which was really effective on the safe side. When the Vision Technique obtained the vision inside, Xi Ran saw through the magic map that there was not even a light spot inside, and it was obvious that the elves inside had run away. However, the tinkerer still stayed and kept repairing to confuse Yun Yun.

"You saw it too. I don't need to say what to do. If I have followed me for so long, I still need to say that you are really stupid and hopeless." Xi Ran said directly to Yun Yun through the soul contract, and Yun Yun even had the intention to bite Xi Ran to death. What does stupid and hopeless mean? If she is stupid and hopeless, she would not become a hero. However, she was quite impressed by Xi Ran's foresight. At least she had been attacking outside but did not find that there was no one inside. It was Xi Ran outside the half-map world.
