"What big secret?" Zhang Yi looked at Qiao Xinyi curiously and said.

"I'm afraid only Taizu Long Xingtian knew about this." Qiao Xinyi shook her head. After Long Xingtian destroyed the previous dynasty, the history books, related characters, etc. of the previous dynasty were all destroyed by him, and everything about five thousand years ago was erased.

"No matter what secret he has, it's not our business anyway, right? Brother-in-law, sister-in-law, come and see!" Huang Jingcheng shouted a little confusedly. He called Zhang Yi brother-in-law, and then called Qiao Xinyi, and this was just a random call.

However, Zhang Yi and Qiao Xinyi didn't care, but followed him under a stone wall in the corridor.

There is a pool of water here and a smell of urine. It looks like yellow - Jingcheng is here!

"What are you doing?" Zhang Yi frowned.

Qiao was also amused and crying. He had urinated on this place. He even brought them over to see the map he drew?

"Look at you, you can't think I'm dirty. I'm urinating. I'm urinating strangely. Look at what this is." Huang Jingcheng pointed at the Yongtong wall and on the pool of urine.

Zhang Yi and Qiao Xinyi looked at it, and then they really found the strange thing. Because Huang Jingcheng was soaked in urine, there was a square seal under the wall, as if the brick on the wall was a secret lattice!

"Did you see it? It seems to be a secret lattice, but I don't have a knife on my body and I didn't dig it down!" Huang Jingcheng said.

"Then you dig him down." Zhang Yi threw a dagger to Huang Jingcheng: "You urinate, you can do it yourself!"

"I didn't let you do it either, I'll do it." Huang Jingcheng took the dagger, and then dug it hard along the wet gaps.

As he continued to excavate, the brick really began to move outward. After a moment, a large blue brick fell down, and Huang Jingcheng also exclaimed: "It's a pull ring!"

"Huh~" Zhang Yi and Qiao Xinyi looked at each other, and there was a pull ring in the secret compartment? So is this the switch to start here?

"You two retreat, I'll pull it!" Zhang Yi signaled Huang Jingcheng and Qiao Xinyi to retreat, then hooked a finger to the pulling ring in the secret compartment and pulled it hard!

"Wow~"

"Boom~" A piece of bluestone on the ground about ten meters behind the three of them suddenly moved more than fifty centimeters, and then a hole that could only accommodate one person to enter appeared.

"The organ secretly tells you!" The three of them were shocked.

"No, no, it is automatically recovering, let's go down quickly." Qiao Xinyi shouted.

"You guys go down quickly, I will restore this brick." Zhang Yi knew that this might be the biggest secret of the previous dynasty, so he immediately urged the two of them to go down. At the same time, he stuffed the wet blue brick back, then wiped a few handfuls of soil to death with the cracks of the bricks.

"Swoosh~" Zhang Yi jumped in when the dark bluestone grid was about to close. After the bluestone made a bang, he returned to his original appearance, and nothing had changed!

Flames appeared on Zhang Yi's fingertips, and Qiao Xinyi also continuously fired several strands of infant fire, illuminating the hole.

The cave is a winding staircase that is winding downward, very twisty and cannot see the end!

"You two are behind me, don't walk around, be careful of the mechanism!" Qiao Xinyi warned.

"You'd better be behind me. Where can you get the lead?" Zhang Yi pulled Qiao Xinyi behind and began to walk downwards.

Qiao Xinyi smiled and smiled happily.

"Sister-in-law, I remember you had a big bow before, where is the bow?" At this time, Huang Jingcheng suddenly asked.

"I put it away." Qiao Xinyi replied.

"Do you have a magic weapon for storage?" Huang Jingcheng was shocked.

"No, I put the bow into my dantian, but I couldn't put it into my dantian, and it was in my sleeve!" Qiao Xinyi explained.

"Wow, can such a large bow be collected into the Dantian?" Huang Jingcheng said in disbelief.

"Even higher-level magic weapons can be collected into the Dantian, Luo... his fairy sword can also be collected into the Dantian!"

"Cough cough, just call me Zhang Yi." Zhang Yi coughed. He just met Qiao Xinyi, so he didn't know how to call each other in terms of the name.

"Yes." Qiao Xinyi nodded.

"You said my sword can also be collected into the Dantian? How should I collect it?" Zhang Yi asked suddenly.

"Of course it's a blood sacrifice. The process of using your essence and blood sacrifice is not a problem. I will teach you later. After you put it into your dantian, you can resonate with the magic weapon and create a degree of harmony!"

"Okay." Zhang Yi nodded repeatedly.

The steps were very long. The three of them walked down while chatting for more than an hour before finally reaching the bottom of the underground palace.

At the bottom of this place is a huge oval dome, very wide, like a small square. With the light of fire, the three of them also saw that the dome was surrounded by various strange totem carvings.

What's even more strange is that in the center of the dome, there were three villains carved, appearing vividly, two men and one woman, who seemed to push open a door, then saw the sunshine, and escaped from the sky, with a very strange carved mural.

In the center of the dome, there seemed to be a throne, which looked several meters wide and nearly two meters high. There was an ancient bronze sword inserted on the ground under the throne, and there was a stone table in front of the ancient sword, and on the table was a vessel made of skulls and... and a scroll like an imperial edict!

"Brother-in-law, there is a sword over there!" Huang Jingcheng suddenly screamed. He didn't notice anything else, but he stared at the sword!

"I saw it, don't be anxious, don't move, and prevent there from being institution!" Zhang Yi signaled that the three of them should not move, because it seemed like a place for sacrificial sacrifices, very strange.

Zhang Yi continued to scan everything in the dome. In the center of the dome, there was a stove that should be like a elixir furnace, but it had long since disappeared and there was only ash on it.

Apart from these, there is no other item in this huge dome cave, but the ground here also seems to be like a formation, carved with stars, like a map!

"You two are waiting here. I'll go in and tent, don't move!" Zhang Yi was afraid that there would be a sudden danger, so he warned the two of them again not to move, and suddenly his body floated up and flew towards the throne.

"Yi, be careful." Qiao Xinyi whispered.

"I know." Zhang Yi did not look back, and was also alert to everything around him.

Fortunately, nothing strange happened until he flew to the palace.

He landed on the side of the sword, and Ding Qing looked over. It was a bronze sword, but it was not rusted, but dark green all over, and there was no energy fluctuation on it!

"Brother-in-law, give me the sword, I don't have a magic weapon yet!" Huang Jingcheng also knew that the sword was definitely not a vulgar thing, so he looked eager!

"Okay, I'll give it to you!" Zhang Yi's hand suddenly held on the hilt of the sword, and then pulled it out from the bluestone ground!

"Wow~" It seemed that a dark green light flashed for a while, but after just a flash of gravel, the sword became ordinary again!

"Give it to you!" Zhang Yi threw the dark green sword to Huang Jingcheng!

Huang Jingcheng laughed and took it, then he also made a few tricks and shouted: "Good sword, good sword, I don't know how many years have passed. Sister-in-law, look at the sword's edge, it can blow hair and cut off hair, and this sword is absolutely great, let me try it!" Huang Jingcheng said as he turned around and slashed at the stone steps behind!

"Chi~" The sword body slashed directly into the stone steps, like cutting tofu, but it did not have any explosive effect. After this sword, it only proved that the sword was very sharp!

"You can try to recognize your master by dropping blood." Qiao Xinyi thought for a while and said, "Use this sword to cut your chest, contaminate your essence and blood in your heart, and try to sacrifice yourself by using the method of sacrifice!"

"How to sacrifice..."

With a "buzz~", just before Huang Jingcheng finished speaking, suddenly, the direction where Zhang Yi was located shone brightly, and golden light burst out from Zhang Yi's hand, and the one holding the imperial scroll was the one!
Chapter completed!
