Early the next morning, Li Zi'an found the two hidden arrows he shot in the temple, and the other two were pierced on Huang Bo's body and were taken away by the goods. However, Tang Qing prepared a spare sleeve arrow for him, and it didn't hinder anything. And the nib of the pen he had found, and put it back on the pen.

This kind of hidden weapon is useless against opponents of Huang Bo's level, but it is still very powerful against ordinary people, and it is impossible to guard against it.

The brains and blood that spurted out of Huang Bo's head had coagulated, red and black, white and white, still so terrifying.

Li Zi'an climbed up to the altar with an alloy toolbox.

There were a lot of blood stains sprinkled on the patina-colored floor tiles, some of them were Huang Bo's and some of his own.

He wiped the blood he had left behind with his foot.

Although the probability of being taken for research is low, even a 1 in 1,000 chance should be avoided.

Safety is in the details.

Wiping away his bloodstains, Li Zi'an wandered around the altar, looking for any secret doors or something. He had seen every stone brick, but not a single stone brick had any keyholes in it, not even a pattern that looked like a lock.

Li Zi'an stopped in the center of the altar and looked around.

A tall figure walked in from the temple's collapsed gate, still holding a wooden stick in his hand.

Dong Xi came, and her stomach hurt couldn't stop her steps.

Li Zi'an didn't want her to climb the altar, so he walked down with an alloy toolbox and said hello from afar: "Didn't you let you recuperate in the tent, what are you doing here?"

"What is this injury? You were invited by us, and I have to watch you. Dong Xi said.

Li Zi'an walked up to her and said with a smile: "I'm such a big person, I don't need you to look at it, I'm not a child, I won't get lost." ”

Dong Xi looked at Li Zi'an's face: "You misunderstood what I meant." ”

"Huh?"

"I'm worried that you will be hooked up with by a woman, and you will run away to do crooked things and not do the right thing. Dong Xi said.

Li Zi'an was speechless for a moment.

Is it necessary to talk about it on this day?

"Did you find anything?" asked Dong Xi.

Li Zi'an shook his head: "No, I want to go somewhere else to see, Captain Yan said that this ancient city is five square kilometers, and the skeleton before was also found in the sand, I want to try my luck again." ”

"Huang Bo escaped, but maybe when he will come back, I don't worry about you going alone, I'll go with you. Dong Xi said.

Li Zi'an said: "You have injuries on your body, I'd better go alone." ”

"That's not good, I don't worry about you. Dong Xi said.

Li Zi'an thought for a while: "Otherwise, I'll treat you again." ”

Dong Xi's cheeks inexplicably flushed again, but before she could express her attitude, a crisp and pleasant voice flew over from the gate of the temple.

"Uncle!" came Kang Xin.

Dong Xi suddenly felt that it was so difficult, whenever she hesitated to accept Li Zi'an's treatment plan, there was always someone and something to interrupt.

Kangxin trotted over.

It's really choppy.

"Xiaoxin, aren't you going to give Uncle Kang a hand today?" Li Zi'an said.

"I'm here to get you. Kang Xin's face was full of sweet smiles.

Give your dad a hand, how can you give the master a hand incense.

Li Zi'an wanted to say that he didn't need anything, but seeing that people were smiling so sweetly, he couldn't say anything if he refused.

But before Kang Xin ran over, a man's voice flew over again: "Kang Xin, you come here!"

Kang Haichuan also came.

Kang Xin's legs braked suddenly, and she turned around: "Dad, you go alone, I'll help Brother Zi'an." ”

Kang Haichuan said: "Your brother An is a master, what do you want you to help me with? If you don't go with me, I will send you back to the magic capital." ”

Kang Xin stomped her foot angrily and followed Kang Haichuan.

After the father and daughter of the Kang family left, Dong Xi said with a smile: "Yu Meilin is really uneasy to marry a man like you, you see that there are women who are worried about you wherever you go." ”

Li Zi'an didn't want to answer this, and looked up at the roof of the temple.

This part of the roof did not collapse, a few pillars supported a few beams, and rows of rafters were covered with thin, polished stone flakes, the same color as the stone bricks on the ground, and they were also patina-colored.

Li Zi'an suddenly remembered a question: "By the way, the stone used to build the temple is very special, have you taken it for laboratory analysis?"

Dong Xi also looked up at a stone sorghum: "Of course there is, but there is no result yet, after you left last time, I chatted with relevant experts, and he talked to me some." ”

"What did he say?" Li Zi'an also looked at the stone sorghum that Dong Xi was looking at.

Dong Xi said: "That expert is sure that it is a stone. ”

Li Zi'an: "......"

This is really in line with the style of experts' speeches, which makes people feel speechless but unable to refute.

He also said that the stones used to build the temple were extremely rare and that he had never seen them. He is a native of Xindi, a native of Xindi, and he is also a very authoritative geological expert in China, he knows Xindi very well, but he gave a strange statement, he said that these stone Xindi do not exist, and there are no other places, at least in our country. ”

Li Zi'an said curiously: "These stone pillars and beams are all whole, and the stone used for carving must be larger, if you don't use local materials, how can you transport them from far away? And the expert also said that there is no such stone in Xindi, not even in other places in China, so where did it come from?"

Dong Xi shrugged his shoulders: "I don't know, the expert said that this matter is more strange than the mystery of the construction of the pyramids in Egypt, because the stones used to build the pyramids are still nowhere to be found, but the stones used in this temple are nowhere to be found." Moreover, in terms of construction technology, it is also a miracle, unlike the ancients who could have built it more than 3,000 years ago. ”

"It can't be built by aliens, right?" Li Zi'an gave a bold hypothesis.

If you don't understand something, just push it to the aliens.

Dong Xi looked at Li Zi'an: "That expert also said so." ”

Li Zi'an said with a smile: "Then I am also an expert." ”

But at this time, something suddenly flashed in Li Zi'an's mind. It was like an idea flashed in my head before I was ready to write an article, and I was excited and confident, but when I picked up the pen, I found that there was nothing in my head.

"Don't look at it, didn't you say you were going out to try your luck, let's go. Dong Xi said.

"Wait. Li Zi'an still maintained the posture of looking up at the roof.

Dong Xi raised his head again, looked at the place where Li Zi'an was looking, and asked curiously, "Did you find anything?"

"Nope. Li Zi'an's answer was very crisp.

"Why are you looking at it like this?" Dong Xi went to see Li Zi'an again.

Side-facing killing.

That inspiration and strange feeling returned.

Li Zi'an pondered for a moment before saying, "We are standing in the middle of two stone pillars, right?"

Dong Xi looked left and right: "We are standing in the middle of two stone pillars, what's the problem?"

Li Zi'an said again: "We have a stone beam on our heads, right?"

Dong Xi's face showed a strange expression: "I said what's wrong with you, just ask me some inexplicable questions, are you sick?"

Li Zi'an didn't care, and an excited smile appeared on his face: "Then don't you think that these two stone pillars plus the stone sorghum on top don't look like symbols representing pi π?"

Dong Xi was stunned for a moment, and then looked up again, it was indeed a bit similar, but she couldn't understand why Li Zi'an mentioned this, and she was so excited.

"Like, what's not, can't you say what you think in your heart at once?" Dong Xi was dissatisfied.

Li Zi'an raised his hand and pointed to the stone sorghum above his head and said, "Look at it again, this beam actually doesn't support the roof, it is more like a decorative door with these two stone pillars, they are different from other pillar heads." ”

Dong Xi didn't want to talk to Li Zi'an anymore.

Li Zi'an squatted down, put the alloy toolbox on the ground, opened the box, and then took out the key from the box.

Dong Xi said curiously: "You said that these two stone pillars are decorative doors, do you want to open the door when you take the key?"

"Yes. Li Zi'an held the key and let the key be infused with true qi.

Dong Xi smiled: "You're not sick, you're guilty of two, you want to open the door, where is the door lock, are you going to open the air door lock?"

Li Zi'an ignored her and continued to pour true qi into the key.

A pattern emits a ray of green light, which is evident in the absence of sunlight even though it is daytime.

Dong Xi's gaze was immediately attracted, and his face was full of surprise: "What's going on with this key?"

Li Zi'an smiled bitterly: "Don't ask me, I really don't know what it's about, I just think I can activate it with my true qi." ”

More and more green light burst out from the key, and finally the whole key was lit up, and the bronze-like material transformed into a material like green jade, the whole body was crystal clear, and the "π" symbol was revealed again.

Dong Xi also saw it, and then she understood what Li Zi'an had been talking to her about the pi symbol for a long time, and she subconsciously looked at the stone pillars on the left and right sides, and then looked up at the stone sorghum above her head. The combination of two stone pillars and a stone sorghum is indeed like a "π", but where should the key be inserted?

"Where's the lock?" she asked.

"Locked in front of your eyes. Li Zi'an said.

Dong Xi looked at Li Zi'an and frowned.

There was only Shuai Qian in front of her, and Shuai An's answer gave her the idea of snatching the key and then poking it into the keyhole on Shuai An's body.

But at this time, Li Zian gently threw out the lighted key in his hand.

The jade-like key fell to the ground with a crisp sound.

An energy fluctuation appeared at that moment, and the key, which had just bounced off the stone slab and had not yet fallen to the ground, was sucked into a stone brick in the middle of the two stone pillars, and then erected on the stone brick.

The ground shook suddenly, and the stone brick slowly rose.
