Soon, Yi Yunfei conducted a new round of searching, tables, chairs, cabinets, boxes, walls, floors, hanging paintings, all missing, this time he was more careful than just now, and even the patterns that looked ordinary tried to press and twist with his fingers.

Finally, he made his way to the kitchen, and after checking everything that could be moved, he looked at the large stove made of blue bricks.

He had already inspected this stove just now, and the stove, which was more than two meters long and more than one meter wide, had two stoves, and both of them were cauldrons of pig iron. Yi Yunfei had already seen it just now, and he had checked every green brick, but he didn't find anything.

But when he saw the two cauldrons at this moment, he remembered a movie he had watched, in which there was a plot where the people in the small courtyard of a farmhouse were besieged, and directly moved the big iron pot on the stove, and below was the tunnel where they escaped.

Reaching out to pick up the big iron pot on the outside, Yi Yunfei easily moved the pig iron cauldron to the side, the stove seemed to have been used, there was gray grass ash inside, and the four walls were smoky pitch black, carefully pressing every place in the stove sect, still didn't find anything, Yi Yunfei didn't do anything, and looked at the other big iron pot inside.

"Finally let me find it!" When Yi Yunfei picked up another big iron pot, he found the clue in it, the iron pot couldn't be served!

The big iron pot on the inside seemed to be stuck with the stove, and Yi Yunfei took it hard a few times, but he couldn't move him. At this moment, how could he not understand the key and instantly know that he had found what he was looking for.

Gently rotate the big iron pot in his hand, and the big iron pot that can't be moved easily rotates on the stove under the condition that he is straining in his hand. One circle, two circles, three circles, and three turns, but no imaginary secret passage appeared.

Yi Yunfei pondered for a moment and turned gently again, but when he turned at this moment, his ears carefully listened to the sound made when he turned the iron pot.

The edge of the iron pot and the stove rubbed against each other, making a somewhat harsh sound, but when Yi Yunfei turned half a circle, he heard an unusual sound, a "ding", which was very crisp. His face moved, and he stopped. After thinking for a while, he continued to rotate in the opposite direction, and heard a soft sound again.

The sound of the clattering mechanism sounded, and the entire stove on the ground slowly rose, and after a while, under the rectangular stove, two people were exposed to the parallel downward steps, which continued to the depths of the ground!

"Damn, I was blinded by Lao Tzu, the Ji family is amazing, and they can even design a combination lock!" Yi Yunfei wiped the beads of sweat that didn't exist on his forehead, and walked quickly towards the bottom of the steps.

The passage was a little dark, it looked very long, and Yi Yun was also very cautious when he flew away! There was no hidden weapon or anything like that, but at the bend of the passage, a small formation was found to warn him. This kind of formation is nothing to Yi Yunfei now, he easily cracked this formation without any sound!

Cracking this formation, there was a big turn in the shape of a corridor in the passage again, behind the curve, there was a faint light coming, Yi Yunfei cautiously approached, released a trace of divine thought, and probed towards the passage behind the curve.

This is a very large space, neatly placed with many Bogu shelves, boxes and cabinets, more than five meters high dome, covered with dense night pearls, making this place as bright as day.

On the Bogu shelf are placed many precious materials, including metals, medicinal herbs, weapons, and many books. Those boxes were all closed, but Yi Yunfei could clearly feel the strong aura emanating from the cracks, and the boxes should contain spirit stones.

"Sure enough, it's a big family, rich!" Yi Yunfei was in a better mood, raised his foot and walked towards the treasure house, after turning the corner, his foot just stepped down, and suddenly a sense of vigilance rose, and before he could react in his mind, his body had already made the most direct response, and his body retreated violently.

The scorching breath suddenly came from the passage behind the bend, and although it was through the thick earthen wall, Yi Yunfei still felt that his skin was roasted by the heat. In the blink of an eye, the thick earthen wall was burned red, and his clothes and hair smelled burnt.

If it weren't for his quick reaction, it is estimated that he would have been burned to charcoal at this moment! Yi Yunfei still underestimated the Ji family, such an important treasure house, how could there be no defense mechanism! After waiting for five minutes, the flames stopped, and the entire passage was filled with hot gas. If it weren't for Yi Yunfei's strong physique, I don't know how far he would have to retreat to withstand this heat wave!

Passing through the passage of the heat wave step by step, Yi Yunfei was much more cautious, but in the entire Qianwei County, there were not many formation masters themselves. And in order to keep it a secret, the Ji family naturally did not invite outsiders to help them set up the formation. After cracking the attack formation just now, it was smooth all the way, and there were no more accidents until it reached the treasure house.

Without time to check, Yi Yunfei took out the space ring on his chest, regardless of the three-seven-twenty-one, and stuffed the things he could see into the space ring one by one.

The spirit stones in the boxes were almost all mid-grade spirit stones, there were six large boxes! There were also countless books, the six families of Nanguang, all of them had a long history, and their collection of books was not much more valuable than the books that Yi Yunfei obtained from those sects that were destroyed by Yi Yunzong.

Weapons, swords, guns, swords, halberds, almost everything, although I didn't see the flying swords that Yi Yunfei had always wanted, but if these weapons were taken out, they would also be treasures that would be robbed of their heads. Medicinal herbs, many medicinal herbs know at a glance that the year is long and the medicinal power is strong!

Yi Yunfei didn't have a good impression of the Ji family, and all the things in this treasure house were all received in the space ring, even the shelves where the items were placed were not spared, and even the ornaments and paintings hanging on the walls were also taken away. volleyed into the air, and the night pearls on the top were also dug up, leaving only one.

Only the last pearl of the night remained, and the treasure vault had changed from bright as day to dim light, and at this moment the treasure vault could be described as bleak and bleak, and the treasure cave full of places was now empty.

Smiling, Yi Yunfei turned around and was about to go out, but as soon as he stepped out, he stopped.

"No, these things are precious enough, but they haven't reached the point where they need to be guarded against. These books, weapons, and spirit stones can be packed with things like space rings or mustard seed bags, and stored in a more secret location, and there is no need to open up such a large underground space at all!" "From the moment he entered this courtyard, Yi Yunfei felt that there was weirdness everywhere here, and everything seemed to be very reasonable, but in a family like the Ji family, the more reasonable things were, the more unreasonable they were.

"No, no, I have to check it!" Yi Yunfei turned around and walked towards the treasure vault again, searching and checking inch by inch.

Just when he reached out and knocked on the wall, he finally noticed something different, there was a knock on the wall, there was a hollow sound inside, Yi Yunfei paused, and stopped.

"What a careful mind, there is another treasure cave in the treasure cave, and it is also placed in the most conspicuous place when entering the door, but it is the most easily ignored!"

Yi Yunfei's eyes lit up, and he looked down at the very ordinary-looking wall in front of him.

Soon he found that one of the bricks built on the wall was smoother than the others, and the gaps between the intervals were more obvious than the gaps between the other bricks, and the gaps were not so obvious that they could not be found if they did not look carefully.

Yi Yunfei pressed down gently, and the blue brick did not move.

He took out a dagger from the space ring and gently pried the green brick, and soon, the green brick was pried out of the wall.

Pulling out this green brick, Yi Yunfei looked down at the gap, and in the gap, there was indeed a circular mechanism.

Pressing, turning, shaking, and after trying a few times, Yi Yunfei quickly found that this mechanism was the same as the mechanism of the combination lock of the pig iron cauldron, and with the experience of opening the secret passage, in a few moments, he opened this mechanism.
