When he answered the phone, Tang Xingchao's voice came from inside.

"Mr. Lu, I have asked Momo to deliver the things to you. Have you received them?"

Lu Tianlong said: "I received it, but this is your heirloom, so precious..." Before he finished speaking, he was interrupted by Tang Xingchao.

"There is no value? Compared to our entire Tang family, it is really insignificant."

"But yesterday, time was tight and I didn't have time to tell Mr. Lu, so I'll call you now."

"To be honest, although this is a family heirloom of our Tang family, I'm really sorry. I don't know what is inside."

"I even tried many ways but couldn't open the wooden box."

"It's just that the Tang family has ancestral teachings, and only those who are powerful can achieve it."

Tang Xingchao apologized on the phone, but it turned out that he had never opened the wooden box, and even the ancestors had been like this for generations.

After chatting for a while, Lu Tianlong became more and more curious about the wooden box.

He tried various methods and even wanted to destroy it violently. But what was surprising was that although this wooden box looked ordinary, if it really used powerful means, a magical force would be generated on it, which directly swallowed the power of the outside world.

"Why try other methods, such as the power of the dragon vein?"

The Tang family heirloom comes from the Qinling Mountains. Combined with the introduction of Xuanyuan Yun yesterday, this thought flashed through Lu Tianlong's mind.

Then he mobilized the power of the dragon vein in his body and slowly injected it into the wooden box in front of him.

Something magic happened! "Bang!"

With a crisp sound, it seemed that the hidden lock of the wooden box popped open.

Lu Tianlong was lifting the lid of the wooden box, but it opened it without any effort! In the wooden box, there was an iron book! It was said to be an iron book, but Lu Tianlong actually didn't know what material the book was made of. It was heavy in his hand, as if it was weighed as a thousand pounds.

"I don't even know this kind of material."

He rubbed his fingers on the mottled book, and Lu Tianlong murmured, feeling that this was more like a piece of ancient meteorite.

There are seven pages of iron books.

Lu Tianlong looked through it and found that each page of the seven pages of the Iron Book was covered with some strange patterns.

If you look closely, each page is actually a three-dimensional pattern.

It is like the pictures of the three places, with mountains, rivers, and plains painted on it. It makes people see it at a glance and a three-dimensional picture can appear in their minds.

"Every page is a map."

Lu Tianlong looked through it and thought to himself.

However, in the center of each page, there is still a black stone the size of a fingertip is inlaid.

"What does this stone mean?"

Lu Tianlong was a little puzzled. He carefully observed the black stone. The location was almost in the center of each page, but it was not completely similar.

When comparing the positions of these seven stones alone, there is no rule, and it seems that they are just put on it at will.

"What's the situation?"

Lu Tianlong was confused. This was the heirloom of the Tang family. According to Tang Xingchao, this thing is naturally very valuable.

Moreover, Xuanyuan Yun also said before that the old man who was one or two hundred years old in the mountain also said that to open the ancient imperial tomb in Qin Mountain, he needed the heirloom of the Tang family.

But how do you use this thing?

Now I hold this seven-page iron book in my hand, I just feel very heavy, and there is nothing magical about it other than that.

"Ying, go and find the brothers, and Xuanyuan Yun, call them together."

Lu Tianlong thought of a solution but failed, and immediately ordered.

Soon, Qing'er led many brothers into the hall, and Xuanyuan Yun also ran in as soon as possible.

Lu Tianlong described what happened just now and asked them to analyze the seven-page iron book.

Unfortunately, all the War Dragon brothers, including Qing'er, Wen Tianhao and others, were confused like Lu Tianlong just now, and had no idea what the seven-page iron book meant.

Some people say this is the key, find the entrance to the ancient land and insert the iron book into it?

Some people say that this may be sealed and requires magical power to be untied.

In short, everyone discussed, analyzed and tried, but still had no effect.

In the end, Lu Tianlong could only look at Xuanyuan Yun, with a little resentment in his eyes.

Xuanyuan Yun had been locked behind and didn't dare to speak. Now, seeing Lu Tianlong staring at him like this, he was so anxious that he was about to cry.

"Mr. Lu, it's all my fault. I shouldn't have killed the old man in the mountains."

"When the matter is done here, I will immediately wear mourning and keep the tomb for a year, no, a year and a half..." This guy was racking his brains just now, but he found nothing with Qing'er and others. Now seeing Lu Tianlong staring at him, he immediately took the lead in admitting his mistake.

If the old man in the mountains is still there, maybe he can get some useful clues.

But, there is no if.

"Forget it, I'd better call Tang Xingchao, no, let him come here directly."

Lu Tianlong pondered for a moment.

After all, this is a family heirloom of the Tang family, so maybe it will provide some clues.

After the phone call, not long after Tang Xingchao came to the hall, and Tang Momo also lowered his head and followed him without saying a word.

When Tang Xingchao saw the wooden box being opened, he was also very excited. While observing the iron book inside, he praised Lu Tianlong without hesitation.

However, Lu Tianlong did not listen to these compliments, so he expressed his doubts just now, wanting to see if Tang Xingchao could provide some clues.

"What is the purpose of these seven-page iron book?"

After hearing this, Tang Xingchao was also stunned.

Then he smiled bitterly and shook his head, "Mr. Lu, I really don't know about this. We have not opened this wooden box for several generations."

"I don't even know that this thing is actually put in it."

"I have read all the ancestral classics a long time ago, and there is no record. It's just that the ancestors of the Tang family once left a sentence that non-powerful people cannot open this box."

The result is very frustrating.

Originally, Lu Tianlong still had great hope and wanted to use the Tang family heirloom to explore the ancient land in Qinshan to see if it was the imperial tomb of the eternal emperor and whether it had dragon veins.

But now, this Tang family heirloom is useless to him! "Mr. Lu."

At this moment, Tang Momo, who had been standing next to him and had not spoken, suddenly hesitated.

“I like adventure and wild travel.”

"Especially the Qinling Mountains, I have been to almost all the places I can go to over the years."

Everyone turned their heads to look at her, their eyes full of confusion, and they were thinking about this heirloom, and she suddenly said what she did.

Tang Momo hurriedly said: "I just think that these seven-page iron book do not seem to exist alone."

"I look at the terrain on every page, and I'm thinking, if they are connected..." Hum?

Before Tang Momo could finish his words, Lu Tianlong's eyes suddenly lit up.

He arranged the iron book in his hand in order one by one, and spread it directly on the coffee table in front of him.

Looking down at the past, a magnificent scene appeared.
