In fact, the light in the hall was relatively dim, and Lu Cheng couldn't really see it even if he wanted to. Song Ping went to invite Song Kaixuan, but he stayed bored in the hall, and he didn't dare to sit on the chair, so he had to play with induction. Now he can see the situation in Erzhang, so he simply probed the induction to the ground.

Lu Cheng had always felt that his sensing range was two zhang, but when he put the sensing power underground, he immediately felt that the distance had been reduced by more than half. Although he did not have an accurate measurement, he could only use induction to reach a zhang at most. Lu Cheng's feet are all whole green bricks, and the ground can be paved with green bricks, which shows the luxury of Songjiazhuang. But under the blue bricks, there is also a layer of bluestone slabs. Like the front lawn, it's all whole.

Ordinary people can pave the ground with gravel, even if they are very particular. If you can pave the ground with bluestone, it must be a wealthy family, and ordinary people will never be able to do it. As for paving the ground with green bricks, it is definitely a family that is either rich or expensive. Under the blue bricks, bluestone is also used as the base, which is even more difficult for ordinary rich and noble families to do.

Under the bluestone is the loess, Lu Cheng waited boredly, since he couldn't sit, he had to walk back and forth in the living room. Anyway, there was no one around, and no one came to restrain him. Lu Cheng released both induction forces and penetrated them from under his feet.

Although it was only his induction power that drilled into the ground, the induction to Lu Cheng was as if he had drilled into the soil by himself. Just like the earthwalker in the mythical story, Lu Cheng feels that he is now an earthwalker. It was a wonderful feeling, and he walked around the hall, experiencing the joy of being a dirtwalker.

When Lu Cheng walked to the door of the hall, he suddenly found something under his feet. This made him stunned, he basically walked through the empty space of the hall, and there were some stones under the bluestone except for the loess, and there was nothing abnormal at all. But now, he found a big guy. He perceived it carefully, and slowly determined the exact location.

When he walked in just now, Lu Cheng didn't notice that there was an iron box under the threshold. Of course, the so-called threshold below refers to the blue bricks under the threshold, and under the bluestone under the green bricks, there is also a layer of loess nearly one zhang thick, and then a small space is enclosed with bluestone, which can just be placed in an iron box.

I don't know how many years this iron box has been placed here, the surface has been rusted, maybe it was buried under it when Songjiazhuang was first built. Lu Cheng really wanted to see what was inside, but after his induction power entered the ground, it was shortened by half, and when he faced this iron box, he could only sigh.

"Lu Cheng, what are you doing?!" When Song Ping came back, he saw Lu Cheng standing at the gate with his head down, as if flowers were carved on the green bricks on the ground, and he said angrily. What kind of performance is this? Even if he saves the two Song family disciples today, he can't be so unruly, right? No matter what, Lu Cheng is still a miscellaneous servant after all, and this has not changed.

"Deacon Song, what about the second young master?" Lu Cheng asked, he can also receive the monthly silver now, from this point of view, he has the same status as Song Ping.

"You come with me, the second young master wants to see you. Song Ping suddenly remembered Song Kaixuan's words, "Please" Lu Cheng to his courtyard.

The descendants of Songjiazhuang have their own separate small courtyards, Lu Cheng had only heard of them before, and after following Song Ping, he found that these separate small courtyards were much larger than his own home. Song Kaixuan's courtyard has two entrances, the front one is occupied by the subordinates who serve him, and the back is his residence. There are special practice rooms and study rooms, and the area of the courtyard is very large, which is more than ten times larger than Lu Cheng's house.

Looking at such a good courtyard, Lu Cheng was very envious, and he didn't know when he would be able to live in such a courtyard. As soon as he entered, he sensed it with his senses, and there were two rooms underground, one was a quiet room and the other was a practice room. Song Kaixuan occupied such a large courtyard alone, it was really a waste.

"Second Young Master, Lu Cheng is here. Song Ping took Lu Cheng to Song Kaixuan's study and said respectfully.

"Second Young Master, the skin bag has been found, do you see if this is it?" Lu Cheng immediately took out the skin bag and handed it to Song Kaixuan with both hands.

Song Kaixuan took the leather bag and looked at it carefully. This skin of his is specially made, and the opening on it is tied with a special knot, if it is not a disciple of the Song family, he will not be able to solve it at all, let alone tie it. He has seen it, and Lu Cheng has definitely not opened this skin.

"Lu Cheng, thank you. Song Kaixuan carefully put the skin bag into his arms, which contained the longitudinal technique he was cultivating, if it was spread out, it would cause a great loss. Lu Cheng was able to help himself find it, which really helped him a lot.

If Song Kaixuan knew that Lu Cheng had not only seen the longitudinal technique in his skin, but also practiced the longitudinal technique, I wonder if he would have thanked Lu Cheng so sincerely? I am afraid that not only will he not sit back and thank Lu Cheng, but he will hunt down and kill Lu Cheng.

"That's what I'm supposed to do. Lu Cheng hurriedly said that he took advantage of Song Kaixuan this time, and after learning the body technique, life will be more fun.

"Lu Cheng, I have already reported to my father about the fact that you saved my third and fifth brothers today. Since you don't want to come to the inner courtyard as a guard, we won't force it. When you want to come in in the future, you can always tell Song Ping. And this is ten taels of silver, which is considered a reward for you. Song Kaixuan took out a pair of gold ingots, and today's events still feel extremely dangerous in retrospect.

"Thank you, Second Young Master. Lu Cheng sighed inwardly, he found another martial arts secret book in Song Kaixuan's study, if he was given a choice, he would rather stay here for two more hours than the ten taels of silver. But after taking the money, you can only leave, and you will come here again in the future, I don't know when.

"Deacon Song, Songjiazhuang is so big, the first owner of the village must have been wealthy, right?" After Lu Cheng came out, he kept thinking about the iron box under the threshold of the front yard hall. His senses weren't strong enough to look inside the iron box, but the more he couldn't see what was inside, the more curious he became.

"You are wrong, the inner courtyard built by the first owner of the village is very simple, but it has always been the residence of the owner. It wasn't until 60 years after the village was built that the front yard was rebuilt. Songjiazhuang has also developed bit by bit, and the hardships during the period are not enough for outsiders. Song Ping said that when the first owner came to the foot of Datong Mountain, he was also a thatched house at the beginning, and Songjiazhuang can have the current scale, which is the credit of the previous owners.

Lu Cheng didn't speak, just looked at the threshold of the hall in the distance and nodded thoughtfully.
