It turned out that the magic circle above the valley could not carry any magic weapons into it.

Once the magic weapon is carried, the circle will blast the trespasser into ashes with thunder.

Xu Tianhai had sensed that the old woman had a magic weapon aura on her body before, and he felt that she was blown into ashes by the thunder, which should be related to the magic weapon aura on her body.

But he couldn't figure it out, he thought that the old woman should have carried a magic weapon before, why the old woman was fine before, but now she is in trouble.

And what puzzled him was that he really couldn't understand why the old woman didn't look around, or still be able to find some useful clues, but she had been trapped here.

From some of the letters inside the storage ring, he knew that this place was the Thunder Annihilation Heavenly Array in ancient times.

The function of this Thunder Annihilation Array is to prevent the demons from entering the magic circle, and then teleport to other places through the teleportation circle in the magic circle.

When the situation of the arrangers here is critical, they will leave some clues so that the Terran warriors who arrive here later know how to leave here.

The stone tablet that Xu Tianhai found before was the clue that some Terran warriors who escaped first deliberately stayed here after the situation in this place was critical.

As long as the Terran warriors who came from behind carefully put together the stone tablet, they could find a way out.

Xu Tianhai pondered for a long time before he thought of a possibility.

"This Thunder Annihilation Array is very likely to be a double magic array, first of all, if you want to leave here, you need to leave when the sun is shining here, and the person who leaves can't carry any magic weapons or practice any demon exercises, once the Thunder Annihilation Heaven Array senses that the intruder has a magic weapon or a demon breath, then it will release a wild thunder and blast the intruder into ashes! That old woman hadn't left here when the sun was shining before, but this time, although she chose to leave when the sun was shining, she had a magic weapon on her, so she was killed by the thunder of the Thunder Destroying Heavenly Array!"

After thinking clearly about the twists and turns, Xu Tianhai breathed a sigh of relief.

He examined the bones on the ground again, and he judged from them that they were some seriously injured dead people who had been placed in the cave before, but then they died and the cave collapsed.

And that old woman has been trapped here for some reason.

She didn't search every corner of this place properly, she could only look at the gray Baoshan, and thought that there was no Baoshan here, and finally missed Baoshan in vain.

In fact, Xu Tianhai didn't know that the old lady didn't know the words on the stele, even if she let the old woman see the complete stele, she couldn't understand what the words on the stele meant.

Moreover, even if the old woman were to find the collapsed cave he had found, she would not be able to read the words of the letters.

However, what made Xu Tianhai happiest was that he found a map of the former Desolate Ancient Holy Land in a storage ring, and when he looked at the map, he realized that the place where they were now located was the center of the Desolate Ancient Holy Land.

"It seems that this high mountain is the only way for those Terran warriors to leave here before! no wonder this place is so mysterious!"

Xu Tianhai suddenly realized.

"The scorching sun has ended, and it will take more than twenty days before the sun shines here again!"

Xu Tianhai also carefully checked the pills in the storage ring, and to his disappointment, he finally found that all the medicinal properties of those pills were invalid.

He continued to search the cave several times, but in the end he did not find any new clues.

After making sure there really weren't any new clues, he returned to his cave.

And Lin Xiyu, who was not far away, was secretly preparing to deal with him, she knew that now they were alone here.

If Xu Tianhai really used force on her, she could only kill him.

Xu Tianhai was focused on finding clues to leave this place, and he didn't know that Lin Xiyu had ten thousand fears of him.

Lin Xiyu has always been wary of Xu Tianhai, so she didn't know that Xu Tianhai had found useful clues.

Time flowed like water, and after more than 20 days, Xu Tianhai decided to tell Lin Xiyu two or three days in advance, so that she could prepare to leave here.

"Miss Lin, I'm looking for you in the next place!"

Just outside her cave entrance, Xu Tianhai said respectfully.

Lin Xiyu in the cave listened to Xu Tianhai's words and suddenly became nervous.

"He's finally going to be hard!"

She also thought that Xu Tianhai was looking for her at this time, and he should want the overlord to take the bow!

"If you have something, just say it outside!"

Lin Xiyu's eyes flickered and replied.

At the same time, she had prepared a poisoned crossbow arrow, and she aimed the tip of the crossbow arrow at the entrance of the cave in front of her.

"Miss Lin, I've already found a way to get out of here! Two or three days is the best time for me to leave here with you! I found some clues in a nearby cave before, and I realized that if I wanted to leave here, in addition to leaving when the sun was shining, at the same time, I also needed to have no magic weapon or any demon breath on the interloper! Once the Thunder Annihilation Heavenly Array above sensed that there was a magic weapon or demon breath on the interloper's body, it would trigger a thunder attack! It is very likely that the old woman from before had a magic weapon on her body, so she was blasted to ashes in the end!"

Xu Tianhai said.

"Who told you this?"

Lin Xiyu suddenly didn't believe what Xu Tianhai said.

Xu Tianhai immediately said: "I found some clues in a cave in front of me before, I can take you to that cave to have a look now!"

When Lin Xiyu heard this, he suddenly felt that this was most likely Xu Tianhai's conspiracy.

"Maybe he's trying to lure me out of here, and then insult me right in front!

The thought raced through her mind.

"I believe you, I'm not going to go!"

Lin Xiyu replied lightly.

"If you can trust me, that's the best!Miss Lin, let me tell you, you must not have any magic weapons or any items that are tainted with the aura of the demon race!"

Xu Tianhai said very seriously.

"Okay!"

Lin Xiyu replied nonchalantly.

"You check your belongings first, and I'll take you to the valley ahead tomorrow or the day after tomorrow, and then I'll see if we can leave together. ”

Xu Tianhai said.

"Okay!"

She still answered nonchalantly.

"I'll see what you're going to do next?"

However, she had a different idea in her heart.

Two days later, Xu Tianhai came to her cave and told her to go out.

At this time, she was ready for all kinds of battles, and she was suspicious of Xu Tianhai.

Xu Tianhai's brows furrowed slightly, and he sensed a faint demonic aura on her body.
