Yin Bing slapped his forehead helplessly, he didn't follow, Shi Wu's combat power was higher than Yin Bing when Yin Bing was not desperate, so it was not Yin Bing's turn to protect him.

Yin Bing looked back and looked around carefully, he returned to the empty wall of the apse that had been damaged, there was a very obvious trace of the doorway, and there were two intact wooden doors on both sides of the doorway, and the empty wall fell from the top of the doorway.

At this time, Yin Bing touched his chin, it seems that the main entrance of this apse should be open at the back. That wall was manipulated from the outside. It's a strange structure, if this place is sealed from the outside, the people inside should still be able to enter and exit the main hall, right?

Yin Bing went around to the back of the tower and looked at the houses, although they were covered by yellow sand, but through the number of vaguely recognizable roofs, it could be seen that there were more than 30 houses. Yin Bing thought about it, these numbers were not enough to be called a town.

He looked up at the stone wall at the top of the cave, where there was solid sandstone, so this ...... , Yin Bing had a flash of inspiration in his mind, and seemed to think of something.

At this time, Shi Wu had already run back in a hurry, but looking at his dejected appearance, Yin Bing knew that his guess was right. However, Yin Bing asked with a deliberate smile, "Did you find anyone in those houses?"

Shi Wu shook his head in frustration, and then he suddenly remembered something, raised his head and stared at Yin Bing tightly: "What did you say when I ran out just now?"

Yin Bing slapped his forehead with his hand again, and said in despair: "I said that I think there should be no one in those houses!"

Shi Wu said in surprise: "Then why did you let me see it?"

Yin Bing was completely desperate, "It seems like a mistake to bring you here, this mission doesn't seem to require force value." I was just guessing and wanted to go there when we couldn't find any other clues. As a result, you rushed out again before I could finish speaking, where can I stop you!"

Shi Wu scratched his head embarrassedly again, "Hehe, then how did you guess that there was no one in those houses?"

"There is only one truth!"

Seeing that the honest Shi Wu also rolled his eyes at himself, Yin Bing restrained himself and said in a normal tone: "Xiao Wu, don't you think that the number of these houses is a bit small if it is a town?"

Shi Wu touched his chin thoughtfully and nodded, "Yes, it's a little less, then this is not a town, what is it?"

"I think this must have been an underground palace in the first place, and the people who lived in the houses were the servants of this underground palace. When a rain of sand fell on the ground, and the rain of sand extinguished the flames of the old man who was about to be executed, the witch seized the old man who held the relics of the Buddha and went down to the underground palace.

She wanted to take shelter from the sand rain here, but soon the people in the ancient city flocked to the above-ground part of the giant tower to avoid the sand and rain, and as the sand rain fell more and more, the above-ground part of the ancient tower was also covered with sand and dust.

Some of them stumbled upon the mechanism of the ancient tower and entered the lower level, only to be thought to be a way to survive and swarm down to the underground part of the tower. ”

Yin Bing sat on a pile of ruins, took out a sip of water, and then continued: "And the servants of these underground palaces have accepted the order of the witch to enter the ancient tower from the underground to prevent crazy people from entering the lower level of the ancient tower, and even more to prevent people from discovering the underground palace here. ”

Shi Wu nodded, feeling that Yin Bing's analysis seemed to have some truth, "But why did those people all die in the tower, and even those servants were not spared?" Shi Wu was still a little puzzled.

"There are two possibilities, one is that when people rush down frantically, and the people below desperately resist, it causes the floor to collapse, and everyone dies on this floor, and no one can escape.

Another possibility is that when the witch saw that the chaos was out of her control, she activated the mechanism at the bottom of the tower, blowing up the bottom of the tower, and no one escaped. ”

"What about the old man with the Buddha's relics?"

"He's just outside the tower. From the time it began to rain, he was taken by the witch to the underground palace, and it had been at least ten days since the bottom of the tower had been destroyed. ”

"Why is that? How do you see that?" Shi Wu was even more confused.

"Common sense, look, you are watching murder in the square, and suddenly it rains sand, what is your first reaction?"

Shi Wu scratched his head again, thanks to his thick hair, if he didn't perform a few missions with Yin Bing, he would have to scratch himself bald, "I'll run home!"

"Yes, people started running to their homes at first, and then the sand and rain kept going on and the rain was almost burying their houses in it, and they ran to this tower. ”

Shi Wu suddenly realized, "Oh, I know, that old man was brought down on the first day of the sand and rain, and the people entered the tower after many days. But where would the old man be if he wasn't in the tower, why didn't we see it?"

Yin Bing smiled mysteriously and pointed to the apse that the two had just broken out of, "He was locked up there."

Shi Wu followed Yin Bing to the door of the apse, and Yin Bing said again: "Xiao Wu, you see, this apse originally had a gate, but the door we broke was a secret door, and the mechanism of the gate was outside. And we just saw from the main hall that the apse mechanism is also in the main hall, so in this case, the apse becomes a secret room. ”

Shi Wu stroked his chin vigorously as Yin Bing looked, as if he could increase his wisdom by doing this. But don't say it, the effect of the chin is very fast, and Shi Wuzhen found the problem again, "There are no human bones in the apse?"

"There, because the old man found the mechanism to open the door to the main hall, he was not trapped in the secret room. ”

"And where did he go?"

"If I am right, the skeleton we saw in the side hall is his, and he did not leave here, because he did not want to go, and when he is old, he does not want to leave the place where he has lived all his life. ”

Shi Wu didn't wait for Yin Bing's words to land, rushed into the apse with an arrow step earlier, and ran to the side hall to the skeleton, looking for it carefully.

Yin Bing had nothing to do with Shi Wu, so he had to follow the side hall as well, carefully searching for the bones and their surroundings. Regarding the identity of this skeleton, Yin Bing was just a guess, and there was no basis, so he was also a little nervous.

Shi Wu looked at it for a long time, but found nothing, so he simply lifted the bones and wanted to look under the bed, due to the age, the bones had already been corrupted and very fragile, and the skull fell off. Yin Bing's eyes were sharp, and he saw a little golden light at the skull flashing.

Yin Bing picked up the skull, and a golden round stone the size of a thumb belly fell out of it, the surface was not smooth, but it felt very warm in the hand, like a fine jade. Under the illumination of the light, it is still somewhat transparent, as if emitting a faint fluorescence.

Shi Wu also saw the golden stone in Yin Bing's hand, and shouted in surprise: "Haha, I found it!

Compared with the historical pictures given by Lingtong when receiving the task, this is exactly the treasure that is looking for this mission, Yin Bing couldn't help but smile and breathe a sigh of relief, and finally found it. His first mission after returning to the alliance was finally successfully completed. The joy in Yin Bing's heart was even better than Shi Wu's.

The two put the Buddha's relics into a velvet box prepared in advance, and arranged the old man's bones, and after saluting the old man, they were about to start the flying machine and return to the earthly world.

Suddenly, there was an earth-shattering explosion in my ears, and at the same time the ground shook violently. Shi Wu and Yin Bing stopped starting, and the two of them followed the location where the explosion sounded and returned to the apse. Through the door, I saw Zhang Tiecheng and his party coming out of the hole that exploded on the side of the tower.
