Following Mu Zi'an's journey, Tan He was also full of harvest, and was constantly fed by Mu Zi'an, he was no longer the young beast that could only run wild on the ground at the beginning, and his current strength was estimated to be the Four Elephant Realm among human monks, and the Tan He who reached this realm was even larger, and a pair of huge black wings grew on his back.

"Xiao Jiu, did you write again at home?" Mu Zi'an looked at Xiao Jiu, who was opening the letter, and said.

Xiao Jiu nodded, since he left home, he would send messages to his family every half a month, Xiao Jiu was shocked when he looked at the content of the letter.

Mu Zi'an saw that the expression on Xiao Jiu's face was wrong, and thought that there was something bad in the letter, so he hurriedly asked Xiao Jiu, "What's wrong?" Something happened. ”

Xiao Jiu handed the letter to Mu Zi'an, who looked nervous after seeing the content of the letter seriously.

Younger brother, the border is in an emergency, it seems that there is some unknown creature, the eldest brother and the second brother are seriously injured, and the father has already gone, I know that you and your senior brother are very strong now, although I don't want to, but my sister hopes that you can go and help.

Gu Qingfeng noticed that the two of them looked wrong, and immediately said that if there was anything that needed help, just mention it. With this, the two of them cheered up, and after telling Gu Qingfeng the simple situation, the situation was critical, and there was no time to delay, so they had to hurry to the border.

Mu Zi'an passed a force to Tan He, who was flying with wings under him, and Tan He felt this power, and immediately accelerated his speed and flew towards the border.

After three days of continuous travel, several people came to the periphery of the border, only to see that a little far ahead, the smoke of gunpowder was filled, and many injured people on the road were helped to heal.

Murong Yu couldn't help but be angry when he saw this situation, the land he had relied on for so many years had been destroyed like this, and the enemy would never forgive him.

"Stop, who are you, it's dangerous ahead, hurry up and find a place to hide." A soldier wearing black and red armor and holding a spear stopped Mu Zi'an and the others, "I'm here to help, I don't know where General Murong is now?" “

"General Murong is in the front position, if you go forward, you must be careful, I don't know what kind of creature the enemy is this time, it's very weird." The soldier kindly reminded him and helped one of the wounded to leave.

After learning where Murong Han was, the three of them immediately rushed over.

The closer you get to the front, the louder a strange voice becomes. After a few people came to the front position, they saw Murong Han standing on top of the city tower, looking ahead with a serious face, and when a few people came to the top of the city tower, Mu Zi'an and the others were shocked by the tragic situation in front of them.

Hordes of unknown creatures attacked the wall, the strongest of defenses, and once breached, the consequences would be devastating.

I saw a group of soldiers holding spears to attack the group of unknown creatures, and many monks were also among them, but the group of unknown creatures seemed to have extremely high intelligence, the soldiers were not vulnerable at all, and the group of monks was almost unable to hold on, and after the group of soldiers were defeated by the unknown creatures, they were dragged to the rear and torn apart, which was miserable.

Xiao Jiu vomited when he saw that scene, he was still young and had never seen this kind of world, but this kind of thing would still happen after all, under Mu Zi'an's comfort, Xiao Jiu looked ahead calmly.

"Why are you here?" Murong Han said in surprise when he saw Mu Zi'an and the others.

"Back to my predecessors, we are here to help, after all, this is the land where we live, how can we allow foreign enemies to trample on it at will."

Seeing the determined appearance of Mu Zi'an and the others, Murong Han felt very happy, but he still told them about the dangerous situation ahead.

A month ago, some soldiers were outside the border to exterminate some people who tried to violate the border, but just as they were chasing after them, a ground suddenly cracked, and a bunch of never-before-seen creatures ran out of it, and only one of the soldiers escaped under the hands of the unknown creatures.

After learning this news, the border soldiers immediately put all their troops on alert, and a few days later, a group of unknown creatures came to the border wall, and their leader could not be seen, but the group of unknown creatures was in order.

Under the continuous attacks of the border soldiers and monks from all over the country who came to support, the number of the group of unknown creatures was somewhat reduced, but after a period of time, the number of the group of unknown creatures suddenly increased dramatically, and they continued to press towards the border, until today, many soldiers and monks have died tragically at the hands of this group of unknown creatures.

After learning about this situation, Mu Zi'an also carefully observed those unknown creatures, and found that the faces of those creatures seemed to have a mirror, and when they met soldiers or monks, they would reproduce their appearance, and it seemed that some unknown creatures could not only reproduce their appearance, but also their strength.

After this group of unknown creatures reproduced each other, they attacked individual humans one by one, and the weak ones were quickly defeated, and the strong ones couldn't hold on, and many people panicked because of their similar appearances.

The people on the city wall frowned, but they still let Mu Zi'an discover something, although these unknown creatures can reproduce each other, but it seems that they can only last for about a while, Mu Zi'an told everyone about this discovery, Murong Han also discovered recently, these unknown creatures can be reproduced for about an hour or so, and the Five Elements Realm can only last for half an hour, and it seems that the stronger the strength is, the shorter the time for being reproduced, but so far no one above the Five Elements Realm has been sent out.

When everyone was at a loss, Mu Zi'an stood up and wanted to try this group of unknown creatures, Murong Han pondered for a while after hearing Mu Zi'an's request, but thought that Mu Zi'an's strength was very strong, and that group of unknown creatures had not yet appeared to be particularly powerful, so he agreed to Mu Zi'an to go.

Xiao Jiu stayed by Murong Han's side at a young age, Mu Zi'an took Gu Qingfeng and flew down the city wall on Tan He and flew towards the unknown creatures, the group of unknown creatures seemed to be aware of the existence of Mu Zi'an and the others, and collectively looked at Mu Zi'an, only to see that two of the unknown creatures stood up and turned into Mu Zi'an and Gu Qingfeng.

After Mu Zi'an saw it, he carefully observed and found that although these two unknown creatures copied the appearance of himself and Gu Qingfeng, their momentum was much weaker, and it seemed that they were only copied from each other, and their strength was not copied at all, and Tan He was not copied at all, and now it seems that this group of unknown creatures can only reproduce the appearance of human beings, but not the demon beasts.

Tan He fell to the ground, and the wind from the huge wings fanned back some unknown creatures, and then spewed flames from his mouth to the unknown creatures, only to see the two unknown creatures that copied Mu Zi'an and Gu Qingfeng kicked their feet to the ground, instantly stirring up dust several meters high to block the flames.

"Tan He, you go and help the others, pay attention, although this group of unknown creatures has been reproduced, when they can't make human voices, don't make a mistake." Hearing Mu Zi'an's words, Tan He turned around and flew towards the position on the other side.

Gu Qingfeng looked at Mu Zi'an, who had a serious expression, and said, "Brother Zi'an, don't make a big deal of it, it's better to be careful." “

Mu Zi'an glanced at Gu Qingfeng with a smile, and then raised his sword to slash at the two unknown creatures, and Gu Qingfeng also followed with a fan in his hand when he saw this.

The two unknown creatures saw the two rushing towards them, and hurriedly made the same action to attack the two, but the fake ones were fake after all, and the copied weapons were really shattered, and the two unknown creatures were also repelled by Mu Zi'an and Gu Qingfeng.

Next, no matter how Mu Zi'an and Gu Qingfeng attacked, the two unknown creatures were exactly the same and returned, but they were injured or the two unknown creatures, just when the two wanted to destroy the two unknown creatures, suddenly the two unknown creatures turned hideous, and they became the same after a while.

"Humans, don't get complacent too soon, my master is about to recover, and then it will be your time of death." The two unknown creatures said in a strange voice from their throats.
