"That's a big problem! Logically speaking, the soil in the refill will be very different from the soil in other places, and the soil in the landfill will generally be softer and moist to the touch, but the soil under our feet will give me the same feeling when we walk all the way from under the wall! It is very dry and strong, even the place that was originally landfilled is also dry and strong. Xin'er said solemnly.

"Could it be that this morning's sun has dried the soil in the landfill? Leng Yue said.

"Impossible! Sister Leng Yue, you are not an earth magician, you may not know much about this, if the soil stays in the same place for a long time, the stronger it will be, this has nothing to do with sun and rain, the sun can only reach the surface of the soil, and the moisture structure inside the soil must be shaped after years of precipitation. Like the soil under our feet, it gives me the feeling that it has been precipitating here for at least a hundred years, which is why it has become so strong!" Xin'er said.

"But what does it mean if this land is not strong?" said Siyu.

"This shows that after we landfilled, someone came here and treated the land for a second time! ”

"Who would be so boring to do such a thing?" Sakura couldn't help but say.

"I don't know, but it's not the people on the fence who would be so boring to do such a thing, that is, there are people hiding in this weird forest besides us on the outer wall. ”

Once he said this, the atmosphere instantly became a little weird, Sakura Meng frowned suddenly, her expression was slightly solemn, Siyu pulled the corner of Sakura Meng's clothes tightly and didn't dare to speak, Leng Yue stood aside, lowered her head, and didn't know what she was thinking.

"Xin'er, is it true that only an earth mage can make the soil settle quickly and be strong?" Sakura asked.

"Generally speaking, anyone who can use earth magic is fine, not necessarily limited to earth magicians, but multiple people with earth attributes can also do it. Xin'er explained.

"So, at least how many levels does it take to do this?"

"Actually, it's not difficult to turn the newly turned soil into old, as long as you have a good grasp of the land structure of the place, but if you want to turn such a large area of new soil into old soil in a short period ......of time," Xin'er paused and thought for a while.

"You need at least a magician above level 70!"

Hearing this, the three of them couldn't help but gasp.

"Level 70 ......"

"In other words, there might be a powerful level seventy magician hiding somewhere in the forest, right?" Sakura said in a deep voice.

Xin'er nodded, and immediately shook her head, "I think, maybe not one!

"Two?

Xin'er's eyes were like torches, looking at the dense and gloomy forest in front of her.

"Intuition!"

Following Xin'er's gaze, Sakura squinted slightly, "Then why do you think they are hiding in the forest and disappearing the traces on the ground?"

"The reason why they are hiding in the forest must be that they don't want us to find out, and as for why they want to clean up the traces on the ground, it may be because they may have buried something underneath here, and they don't want the people on our walls to find out!"

After Xin'er finished speaking, Sakura did not choose to continue the question, and the empty plain fell into a deathly silence, only the sound of the wind whimpered around.

"I ...... I said, this is the end of tonight's adventure, let's hurry back and tell Commander Fang about this matter, and he will continue to investigate. ”

Xin'er thought about it and felt that it might indeed be dangerous to continue the in-depth exploration, so it was better to go back and explain this matter to Commander Fang before making a decision.

"Alright then, let's go back first. Xin'er suggested.

The three of them nodded in agreement, and Xin'er was about to return with the three of them, when suddenly!

"Master, master, don't go yet! There's something under your feet! You dig it out first!"

Xin'er subconsciously stopped and responded in her mind: "Little Twitter! Is that you?"

"It's my master!" the little chirping voice sounded in Xin'er's head.

"Great! I can feel your presence again!" Xin'er said in surprise.

"Hee-hee, I've always been able to feel the presence of the owner!" Xiao Chi said.

"Little twitter, wait for me! I'll free you from the Djinn Field soon!" Xin'er said seriously.

"Well, let's not talk about that, master, quick, dig out the things under your feet!"

"Good!"

Siyu and the others saw Xin'er stop and stand in a daze, thinking that something had happened to Xin'er, so they kept shaking Xin'er's body and said, "Xin'er, are you okay?"

Xin'er came back to her senses, looked at the three of them with worries on their faces, shook her head with a smile and said, "It's okay, I was thinking about things just now, and I was a little fascinated by it for a while." ”

"What are you thinking, so focused, we all called you several times and you didn't answer. Siyu said with concern.

"Let's not talk about that, I feel like there's something under our feet, let's dig him out. Xin'er said urgently.

Si Yu looked at his feet, and when he thought that the corpses of countless spirit beasts were buried under his feet, Si Yu felt a little sick to his stomach.

"I said Xin'er, can't you dig tomorrow morning?"

"Of course not, okay, don't complain, Sister Siyu, hurry! We'll leave after digging!" Xin'er said this, and she had already begun to dig the soil under her feet with her bare hands, and Leng Yue and Sakura Meng also helped, and in desperation, Siyu had no choice but to help.

Under the joint excavation of the four people, the soil under the feet of the four people was quickly cut open, and what was buried inside was indeed the corpses of spirit beasts, but most of the corpses of these spirit beasts had already decomposed, leaving only dark white bones mixed in the soil.

"I said Xin'er, is this what you're looking for?" Sakura said a little speechless.

Xin'er was also full of doubts, "Xiao Ji, what you are talking about, shouldn't it be this pile of bones?" ”

"Of course not, master, take a closer look. Xiao Ji said.

Xin'er hesitated for a moment, but finally put her head in front of her to take a closer look at the pair of bones buried in the dirt.

In this dark night, the white bones seemed to be covered with a black veil, which looked a little eerie and a little terrifying.

"Huh......"

Xin'er was puzzled, approached the pile of bones again, and focused her gaze on a point, and the three people around followed Xin'er's gaze, and couldn't help but let out a puzzle.

"Huh?"

Sakura Meng put her finger forward where the two bones were connected and said, "I said Xin'er, is there a black bead there?"

Xin'er stared intently at it, where the two bones were connected, there was indeed a black object, because this object was darker and thicker than the night around it, lying quietly between the two bones, under the white background, Xin'er and the others had to find it.

It's just that as for whether this object is a black bead or not, and what his function is, Xin'er doesn't know.

"Little twitter, is this what you are talking about?" asked Xin'er.

"Yes, yes, yes, that's it, master pick him up!" Xiao Ji said excitedly.

Xin'er was about to reach out to grab the unknown object, when suddenly! The object shook violently twice, directly shattering the surrounding bones and rushing towards Xin'er.

Xin'er was taken aback, shrank her head back, and sat directly on the ground.

The mysterious object slid down the tip of Xin'er's nose into the air and flew towards the depths of the forest, which made Xin'er realize that this thing was indeed a black bead!

At the same time, wisps of black gas suddenly rose from the corpses of the spirit beasts below, and those gases flew out from the pile of corpses and flew in the same direction—the depths of the forest!

The sudden change made the four of them a little confused, but Xin'er's mind sounded a little chirp again.

"Master, master! Hurry! Catch up with that bead! Catch up with those black gases!"

Xin'er nodded, quickly stood up, and chased after the galloping black bead.

Seeing this, Sakura also chased after Xin'er, shouting as she chased, "Xin'er, what are you going to do?

"You...... You guys, come back quickly!" Siyu stood in place and stomped his feet in a hurry.

Leng Yue followed behind Sakura Meng, and while running, she said to Siyu: "Sister Siyu, you go and wait for us under the wall first, and we will come back as soon as we find Xin'er!"

Looking at the background where the three of them gradually disappeared, Siyu hesitated for a moment, and finally gritted his teeth.

"You guys, wait for me!"

With that, the four of them rushed towards the dense forest.

Running at the front are Sakura and Xin'er, although Xin'er is the first to set off, but Sakura Dream is also very fast, and a few dazzling lights come to Xin'er's side in succession.

"Xin'er, why did you run away all of a sudden, go back quickly! it's too dangerous inside!" Sakura shouted to Xin'er as she ran.

"Don't worry, Sister Sakura, I'll be fine, you go back to the wall first and wait for me, I'll be back soon." Xin'er said.

"How can we do that! If we want to go back, we must go back together, we can't leave you alone in this kind of place!"

Seeing that she couldn't persuade Xin'er to return, Sakura Meng had no choice but to say, "Xin'er, it's okay to go into the forest, but can you run slower, Leng Bao and Siyu are still behind, let's wait for her." ”

After Xin'er heard this, she slowed down and waited for Leng Yue and Siyu.

It didn't take long for Leng Yue and Siyu to rush over, and the two of them were panting heavily, obviously just catching up with Xin'er and Sakura Meng made the two of them a little unbearable.

Seeing the two coming, Xin'er slowly stopped, took out her handkerchief again, with a solemn expression, and said to the three of them: "Three sisters, no matter what we see next, don't make a sound, you know?"

The three of them looked at Xin'er's expression, subconsciously swallowed their saliva, and nodded heavily, and Xin'er made the handkerchief bigger, covered the bodies of the four people, and slowly walked forward.
