Two men in black flew down from the air, went to the ground, and walked forward a few steps.

The two of them stood there and stayed for a while.

"boom!"

The ground began to shake, and a huge hole appeared from the ground. They walked directly, and then Ye Zizhen and Master Mu hurriedly followed.

There are stairs underground, and gusts of cold wind come from time to time inside the stairs. Perhaps because of the underground, Ye Zizhen had no doubts.

After a while, Ye Zi really felt that the stairs were too long and felt something was wrong. He was about to use the fire slicing, but was blocked by Master Mu.

"Be careful, there are people ahead."

He had no choice but to give up and continue walking forward with Master Mu.

After walking for a long time, they felt something was wrong, and the speed of walking became more and more difficult, and they took every step steadily.

Afterwards, Ye Zizhen stretched out her feet and tentatively found that the front was empty. He hurriedly stopped Master Mu next to him, and then said, "There is no way ahead."

"See if you go to the right or left." Master Mu touched the surroundings, and finally touched the surrounding walls, and then asked Ye Zizhen to follow him.

Half an hour later, the two of them finally walked out of the ground. After they walked out, they looked at everything in front of them, their eyes full of horror.

At this time, in front of them, it seemed like another world, with the breath of death immersed around them, and a dark green light was emitted around them, and the ground was covered with white bones. When you look closely, it was all about human bones and some skulls.

The moss covered everything on the ground, which was very strange.

Ye Zizhen and Master Mu no longer saw the figures of the two men in black.

They came in with them just now, how could they be so fast?

A low voice came.

"Why did the master refuse to attack Ye Zizhen? This human race is so hateful. He has killed so many of my fellow races."

"Do you think the master will tell you? We should obey our master's words, otherwise we might be the same as the disobedient monster before."

After hearing the sound, Ye Zizhen and Master Mu immediately flew up and hid in the air.

At this time, the bodies of the two monsters shivered, then patrolled the surroundings and left chatting.

"You don't know how miserable the monster died without listening to his master's words? Even his subordinates were spared."

"More than that, all his tribes were killed by their masters."

...

Master? Could it be that the master they mentioned is the same person as the master mentioned by the man in black before?

Ye Zizhen glanced at Master Mu next to him and said in confusion: "Are we going now or continue to check?"

"Whether the two men in black just now came here is still an unknown number, let alone, we will leave as soon as possible!" Master Mu said after lowering his head and being silent for a long time.

Ye Zizhen nodded and then left the place with Master Mu.

It seems that this place should be the nest of some monsters. After finishing the recent work, you can come over to find out.

After leaving, they went directly to Mucheng.

In the shogunate, in the room, Master Mu asked someone to prepare some tea and bring it in.

"Ye Zizhen, their master should know you? Do you have any impression?" Master Mu guessed.

The man in black who I met in recent days, the owner mentioned by Ye Zi really puzzled.

If he really knew this so-called master, how could he have no impression of it?

After hesitating for a moment, Ye Zizhen shook her head and said, "I really have no effect on the man in black they mentioned. However, why didn't this man in black let them attack me? Could it be that he was afraid that I would die?"

"Before seeing that mysterious man, everything is an unknown. He is manipulating everything behind his back. Almost everything has something to do with you. You'd better be careful." Master Mu suddenly realized that since Ye Zizhen came to the war land, strange things slowly happened.

Even though Lord Wen lost something before, no one was discovered, he studied the forbidden technique again. However, after Ye Zizhen came, many doubts were discovered one after another by Ye Zizhen.

It seemed like these things were just breathing to let him know, it was so weird.

Ye Zizhen also noticed this at this time, and his expression was a little ugly. It seemed that everything was manipulated by the mysterious man behind the scenes. However, what exactly did he want to do? Why didn't he let him die? He really couldn't understand.

However, we can't continue to be led down by others like this. We must come up with a quick solution after this matter is over.

Now that the enemy is in the dark, he is in the light, it is very beneficial to him.

"Thank you, Master Mu, for reminding me, I understand." Ye Zizhen nodded and said.

"Has the formation been broken now?" This incident has always made Master Mu confused. The scene where the surrounding barrier suddenly shattered was almost the same as when the formation was destroyed.

"That's right. I just used a little trick, so the scene of the barrier around the boss's body was broken. Lord Mu doesn't have to worry, the formation is intact." Ye Zizhen explained.

"That's good. If you say so, there should be no more problems with Mucheng's formation now." Master Mu breathed a sigh of relief and said.

"There is not much time left now, and they will not come to Muk Castle again. The next three cities should be the next."

"Thank you for this incident. I don't have anything here to help you practice. Why not give this thing to you?" Master Mu took a book from the desk and gave it to Ye Zizhen.

After looking at the rough content above, Ye Zizhen hurriedly said thank you: "Thank you, Master Mu."

Almost all the formations in this book are something he has never seen before, and it is of great help to set up the formation.

Suddenly, his inspiration flashed, and he remembered that in the middle of the four cities, there seemed to be no formation yet. It was the place connecting the four cities, and it was also the weakest place in the four cities.

Maybe the man in black came in from that place, so that no one noticed it.

After thinking of this, Ye Zizhen immediately stood up and bent down and said, "Master Mu, I think another formation needs to be set up. This formation is to protect the most central location of the four cities."

"Where is the location?" Master Mu looked at him in confusion.
