"Zhang Fan, are you really sure you want to investigate these things?" In the room, Zong Li, who had just walked out of the box in Guihai, immediately asked Zhang Fan.

"Of course, it's a little boring to be here anyway, although I can cultivate the realm quietly, but I'm still a little uncomfortable, I still feel that it will be better to comprehend the use of the realm in the middle of the battle." Zhang Fan said with a light smile, not to mention that Zhang Fan himself is also very concerned about the improvement of his own cultivation, and there is no way to improve just by staying here.

"In that case, then listen to you." Zong Li said a word and was speechless.

Zhang Fan smiled and strode out of the house, everything was because Guihai accepted the task of Sanqing Tianzun and investigated the immortals who entered the demon world, but Guihai couldn't leave because of some things, so he 'handed over' this task to Zhang Fan, and Zhang Fan accepted this task when he was idle and bored.

Zhang Fan is not clear about the person under investigation for the time being, but the location is known; He was also extremely surprised when he heard that someone from the fairy realm had entered the demon realm, at least he was a novice who knew that if it wasn't for something particularly important, people from two different worlds would not casually cross the space and enter another plane.

"This must be the place where immortals appear, right?" Zhang Fan reached a desolate plain, which was full of the debris of living things after they died, presenting a dilapidated and depressed atmosphere.

"There's really not a single one here." Zhang Fan looked around, and heard Zong Li say: "Of course, this is the Silent Killing Plain, and several major battles of the demon clan were found here, and it can be said that there are no less than a million people of the demon clan who died here." ”

"No wonder that's the case, no wonder there is such a sense of slaughter." Zhang Fan quietly groaned, and he could indeed feel the heavy killing intent drifting on this plain under his careful feeling.

After looking around, Zhang Fan did not see any traces of someone teleporting, and no one had been here for a long time to see the surrounding environment.

……

"I'm depressed, Guihai isn't lying to me, is he? I've been looking for two days and still haven't found anything, not even the breath of an immortal left. Zhang Fandong sat on the ground with a bang, and all he found in the two consecutive days of using his divine thoughts to search was the eternal aura here.

"Don't complain, the size of the Silent Killing Plains is unimaginable, if the immortals really appear here, it will take a lot of time for you to find them, but if the place where the immortals appear is in the west of the Silent Killing Plains, it will be troublesome."

"What? Is there anything wrong with the west side of the Plains of Silence? ”

"Well, because of several battles of the demon clan, there were countless casualties, and those dead demon undead have not been able to calm down, so the demon saints of that year gathered together and laid out a large array of undead, in order to *** these demon undead, but even so, those undead are still very restless."

Zhang Fan couldn't help frowning when he heard this, it is very dangerous for such a large range of undead to be *** in one place, Zhang Fan doesn't think that people at the level of demon saints will not be able to surpass those undead, I'm afraid they have another reason.

It's just that Zhang Fan has indeed lost confidence after searching for several days in a row, and he has searched out an unknown range in the east, south, and north, but he still hasn't found the breath of the immortals, "I'm afraid we are really going to enter the undead array." ”

"Zhang Fan, tell me honestly, do you improve your cultivation every time you defeat the enemy in battle?"

Zhang Fan was stunned for Zong Li's words, and immediately replied: "Well, that's true. ”

"If that's the case, then I'm 'quite 'like' with you going to the Great Undead Array, I think your strength will be greatly improved there."

Zhang Fan smiled and quickly headed towards the west, if possible, he would indeed improve his strength.

……

"Senior brother, let's go to that place first and inquire about the situation."

"Well, good!"

In a secluded place of the demon clan, two men in white robes strolled by, they were people from the demon world who had come from the fairy world.

The two walked to the place where a demon clan gathered in a tea shed, and asked for a glass of water at random, and one of the men asked, "May I ask where is Duxu City?" ”

The questioner was stunned for a moment, and then said, "Duxu City? Don't you even know where the city is? ”

"Hehe, we have just ascended to the demon realm, so we don't know, this time we want to go to the void to find someone."

"Oh, I see, Duxu City is thousands of miles north from here, you just need to see a strange-shaped pagoda to know."

"Thank you."

Soon, the two of them rested for a while and then left the place, and after flying for a while, one of them asked, "Senior brother, is the person the palace master said really in Duxu City?" ”

"I don't think it's wrong, the palace master has also investigated that person for a long time, but I'm very curious about how other immortals in the demon world are willing to come in."

"Maybe he also has the same magic weapon as us to hide his aura."

In the Silent Killing Plain, Zhang Fan flew for three days in a row and finally arrived at the place where the Demon Saint had laid down the Great Array of the Undead, "What a powerful killing aura." "It wasn't until he approached the edge of the Great Undead Array that Zhang Fan clearly felt the atmosphere here, all around him was a withered yellow color, even if the tenacious plants couldn't grow under the dead breath of the undead.

"One of the functions of the undead array is to absorb the dead qi in the array and release it, in order to prevent the growth of those undead who are *** inside." Zong Li explained.

"So how do we get in? You shouldn't need to break the formation, right? ”

"No, I'll teach you a seal trick to enter, many people in the demon clan will do it."

According to Zong Li's guidance, Zhang Fan was indeed easy to learn, and it was easy to enter the undead array, which really puzzled him, can a formation that many characters can crack really *** so many undead?

……

"Grandpa Guihai, when will Brother Zhang Fan come back?" In the study, Xiaoxiao sat on Guihai's lap, eating snacks in her hands, and her legs swayed as if she was swinging.

"Hehe, smile and don't worry, your brother Zhang Fan will be back soon." Guihai squinted his eyes, his hand gently stroked the smiling hair, and finally his eyes extended to the distant place outside the window, as if he had seen through everything, in fact, he still had some doubts in his heart, if it wasn't for a special reason, he wouldn't let Zhang Fan go to find clues instead of himself, and it was after Zhang Fan seized the 'flower' of the seven nights.

"Zhang Xiaoyou, you must pay attention to yourself."
