Lao Zhong raised the muzzle of the gun a little higher, aiming at Uncle Liu's chest, and under our nervous gaze, Uncle Liu pulled out a black rhinoceros horn from the underwear on his chest and handed it to me.

"How could you have this?" I exclaimed.

"Isn't it strange, this thing, a few of our old buddies had one piece back then, but most of them have passed away, can this thing prove my identity?" Uncle Liu put the things on top of the coffin.

I took the rhinoceros horn and put it in my hand to look at it carefully, making sure that this thing was the same as the one I got from the second master, and then I looked up at him again, "Then who are you?" He shook his head and said It doesn't matter who I am, all in all, I know your grandfather, and for so many years, he has been running around for an ultimate secret, and now the old buddies are dying, walking, and I am the only one left, still running around to protect this secret, I prevent you from getting close to here, I just don't want this secret to be discovered.

"Why?" I asked rhetorically, "What is my grandfather investigating in his life, and he is willing to even ignore his own grandson?" ”

Hearing this, Liu Bo paused, turned his gaze to me, and showed a meaningful expression, he is not ignoring you, for so many years, you have been able to grow up safely, he has actually been by your side, but you don't know.

I thought of Lao Luo, whose identity was a mystery, and suddenly lost his voice, "Could it be that Lao Luo is really my grandfather pretending?" Why did he do it? ”

Uncle Liu said that there was an accident in Niuzigou that year, which led to the innocent death of so many villagers, your grandfather was ashamed, and he couldn't show his true face, and the villagers would not forgive him, so he had to borrow someone else's identity, raise you with his own hands, and guard the tomb of Niuzigou by the way, but who knows, in the end, the secret of that tomb still spread, not only he was in trouble, but even you were involved.

I said, could it be that Lao Luo suddenly returned to his hometown, not because he was old and couldn't do anything, but because he noticed that someone was eyeing the Niuzigou tomb, so he left?

Uncle Liu nodded, yes, Lao Yang also followed your grandfather when he was young, but later, his selfish desires swelled more and more, and finally betrayed everyone, your grandfather was affected by him, and had to live a life of fugitive, when he learned that he had become a professor of archaeology, and decided to bring him into the Niuzigou tomb, your grandfather was afraid that he would be recognized by him, so he had to evacuate first.

Speaking of this, Uncle Liu's eyes were a little complicated, he looked up at the sky, and said with a long sigh, "Your grandfather thought that as long as he left, he would be fine, who knew that the surname Yang was so vicious, and he actually involved you as well, he knew that your grandfather couldn't let you go, so he wanted to take you and blackmail him." ”

It dawned on me that it was no wonder that Professor Yang tried everything possible to implicate me and Ge Zhuang, and also framed us and made me stay in prison for three years, it turned out that he wanted to use this to blackmail my grandfather.

I asked, "And finally, did my grandfather have any contact with the surname Yang?" ”

"You kid is held in the palm of your hand, how can your grandfather not comply? Later, they went down to the tomb of the emperor together, you must know about this, right? Uncle Liu said.

I nodded and said I know about this, we met Brother Corpse in the tomb of Emperor Di, and when we met for the first time, Brother Corpse gave me exactly the same rhinoceros horn, and that rhinoceros horn should be my grandfather's, right?

"That's right!" Uncle Liu looked at me with a smile and explained the doubts in his heart for me, "This rhinoceros horn, there were originally five, your grandfather, the surname Yang and the second child, and return me, the four of us each have mastered one, as for the remaining one, it has always been in the hands of the real Lao Luo, but unfortunately Lao Luo is ...... Alas. ”

I suddenly recalled the zongzi I encountered in the grave pit when I went to the tomb for the first time, and what was hanging on his chest at that time was exactly the same rhinoceros horn that the second master gave me, and a thought suddenly came to my mind, "Could it be that Lao Luo, who was pretended to be by my grandfather for more than ten years, actually died in the tomb of Niuzigou a long time ago?" ”

"How do you know?" This time it was Uncle Liu's turn to be surprised, he looked at me in surprise, and said You found out this yourself?

I smiled bitterly, shook my head and said no, and then told us about the first time we went down to the grave, we were attacked by a zongzi in the tomb, and we got a rhinoceros horn from the zongzi.

After listening to my story, Uncle Liu smiled, "No wonder...... No wonder Lao Luo's rhinoceros horn is missing, it turned out to be spinning around, but it fell into the hands of your kid. ”

I said slowly, there are a lot of lines carved on the rhino horn, which seem to be a treasure map, are there any secrets hidden in these five rhino horns?

Uncle Liu was very surprised, and said with a smile, "Count your kid guessing correctly, the secret that a few of us want to protect is hidden in the five rhinoceros horns, and now you have obtained three, plus my one, it is the fourth, but unfortunately the fifth one belongs to Lao Yang but disappeared, so such a secret, I am afraid that future generations will never have a chance to solve it." ”

"Not necessarily!" Hearing this, Chen Yun stood up with an inexplicable smile on his face, and said to Uncle Liu, "The rhinoceros horn belonging to Professor Yang has not disappeared, but it has been hidden by him. ”

"You found it?" Shocked, I looked back at Chen Yun and said, "Why didn't you tell me about this?" ”

Chen Yun said casually, you didn't ask me. And we didn't know at the time that there were so many secrets hidden on the rhino horn, and in my eyes it was just an ordinary ornament.

I was speechless, but Uncle Liu turned his gaze directly to Chen Yun and said I have always been puzzled, why are you so obsessed with studying the truth about the decline of the Shu civilization in Cuba, who are you?

Chen Yun was very calm, saying that I was just an archaeological researcher who was obsessed with the truth of history.

"Really?" Uncle Liu smiled, shook his head noncommittally, and then shifted his gaze to the coffin, saying that now, I have proved my identity, and I can participate in this step of opening the coffin.

I said wait, you haven't told me how the hell my grandfather died.

"He was cursed by witchcraft thousands of years ago, and his health has not been as good as before these years, and when he died, his whole body liquefied into mercury, and before he died, he told me that he still has a grandson, and he doesn't want him to go astray and be used, so he warned me to find you no matter what, and stop you from continuing to explore the truth about the loss of human civilization." Uncle Liu said slowly, I have tried many ways to stop you, but in the end you still embarked on this road.
