Chen Zhongde's wife and the fourth and fifth sons were taken hostage by Zhang Zuolin and used as bargaining chips to threaten Chen Zhongde.

Chen Zhongde was appointed battalion commander, and the soldiers of one battalion under his command said that they were completely at his disposal, but in fact they were monitoring him. In the first few years, Chen Zhongde only looked for some tombs of the Qing Dynasty in the pass, which were all petty fights, and later as the war progressed, Zhang Zuolin played out outside the pass several times. Wherever Zhang Zuolin's army fought, Chen Zhongde led his sons to dig there. The tomb also got bigger and bigger, and the more it was dug up.

Slowly ten years passed, the fourth and fifth children of the Chen family also joined the tomb robbery camp, and Chen Zhongde's eldest son and third son were hit by the mechanism in the tomb one by one, and died in the process of robbing the tomb. Chen Zhongde's fourth son was killed by the soldiers of another warlord when he moved with the defeat of Zhang Zuolin's troops.

Chen Zhongde was left with his second son and Xiao Wu, who was only a teenager. Xiao Wu is too young, he hasn't learned anything yet, and he can't help much, so he just plays by his side, but the second child of the Chen family has learned the skill of tomb robbing.

At the end of that ancient book of tomb robbery, it is supposed that the previous owner of the ancient book left a record of the location of a tomb somewhere in Shandong. According to the previous owner of the ancient book, this tomb is very strange, from the appearance of this burial method does not conform to the common sense of tombs, and the tomb is well hidden, and no traces of theft have been found. The previous owner of the ancient book recorded the location of the tomb in detail, the surrounding environment, and his analysis, but did not record the robbery. Therefore, Chen Zhongde believes that since this person recorded this tomb in such detail, but there is no follow-up, then it is estimated that this tomb has not been stolen, or the previous owner of the ancient book died in the tomb, so he firmly remembered the location of this tomb.

Chen Zhongde has always hidden the ancient book very well, except for him and the second child of the Chen family, no one knows the location of the ancient book, and even Zhang Zuolin doesn't know that the Chen family's tomb robbery methods are actually handed down from the book, otherwise he would have robbed the ancient book a long time ago, and I don't know how many tomb robberies have been formed.

In 1927, by chance, Chen Zhongde's father and son came to their hometown of Shandong with the troops. The most coincidental thing is that the garrison of the troops is only two hours' walk from the location of the tomb recorded in the last ancient book. Chen Zhongde believed that this was the will of heaven, and that it was God who asked him to steal this tomb.

The Chen family has robbed Zhang Zuolin's tomb for more than ten years, and has been conscientious, and has not secretly hidden a single tomb robbery item, nor has there been a single escape, because Chen Zhongde understands that whether it is private hiding or escaping, it is meaningless. The hidden things will be turned out, people will be caught if they run away, and the monks who run away can't run away from the temple, and their wives are still hostages in the hands of others, so it's better to wait for the opportunity honestly.

Because of the cooperation of the Chen family, after so many years, Zhang Zuolin's soldiers have long relaxed their vigilance against the Chen family. In addition, Zhang Zuolin's troops have been defeated and retreated recently, and the people in the Feng army are panicked, and they are about to retreat outside the gate, and these big-headed soldiers have no heart to supervise the Chen family. The Chen family, father and son, took advantage of the time when the soldiers had no time to take care of him, and used a few nights to secretly steal this tomb. As a result, Chen Zhongde actually encountered the legendary Seven Dead Spirit Protector Array in the tomb, although he did not touch the formation but accidentally hit the mechanism and died in the tomb, before he died, he snatched a box from the tomb, and this box contained the compass in Chen Ziyang's hand.

The second elder of the Chen family led the fifth elder of the Chen family and secretly returned to the Northeast after Chen Zhongde's death. Taking advantage of the fact that Zhang Zuolin was beaten, he secretly picked up their mother and hid somewhere in Jilin Province. That is, now Chen Ziyang's hometown, Big Walnut Town. The second child of the Chen family followed his father's last wish and decided to let his descendants stop robbing tombs, but he was unwilling to let his father die so unclear, so he did not follow his father's instructions to burn those ancient books, but hid the ancient books, and left this paragraph of the record in the compass, hoping that his descendants could discover the secret in the compass and solve the cause of Chen Zhongde's death by chance.

After reading the story, Chen Ziyang hurriedly ran to his grandmother's house and inquired about his grandfather's situation in detail with his grandmother. roughly understood that the second eldest of the Chen family was his grandfather, and his fifth grandfather was the fifth child of the Chen family, and soon after following the Chen family to Dawalnut Town, he was arrested by the Japanese to be a miner with his grandfather, and died in the mine cave because he was too young and tired. And Chen Ziyang's grandfather survived until liberation, but although he gave birth to a bunch of sons, he did not pass on the skill of tomb robbing.

Chen Ziyang's heart couldn't calm down for a long time, he couldn't imagine that his grandfather and grandfather would have such a bullish experience. Chen Ziyang turned his head to look in the direction of the blood spirit coffin, thinking in his heart, he didn't know if his fifth grandfather was also buried there by the Japanese in the first place.

What is recorded in this booklet next is Chen Ziyang's grandfather's analysis of this compass. Chen Ziyang's grandfather has already disassembled this compass and put it back on, and has looked at it countless times from the inside to the outside, this compass is just an ordinary compass, and there is nothing special about it. The only thing worth noting is the writing of those sixty jiazi on the inner disk of the compass, and the outer 20 layers.

According to Chen Ziyang's grandfather's analysis, these sixty Jiazi characters should be a kind of control code, and there was also a booklet in the baggage along with the compass in the coffin at that time, but when the compass was transmitted, the booklet fell out and was left in the tomb with Chen Ziyang's great-grandfather. According to Chen Ziyang's grandfather's analysis, the sixty jiazi on the compass are actually numbers, and the meaning of them will only be revealed after comparing what is written on the lost booklet.

For example, the "Jiawu" on the compass is the 4th of the 60 Jiazi, so it represents 4, and the "Jiahai" is the last and the first of the 60 Jiazi, so it represents 60 and 1, that is, 61. According to this line of thinking, the characters of these sixty jiazi represent the fourth character of the lost booklet, and then the sixty-first character below...... As for whether this is really the case, it is impossible to verify that the pamphlet was lost. But Chen Ziyang's grandfather can be sure that there is indeed a big secret hidden in this compass, otherwise there would be no Seven Dead Spirit Protector Array to guard that tomb.
