Qin Dong looked at this process, his eyes did not blink, the entire slaughter process was seen by him clearly, without the slightest omission, he kept biting his lip to prevent himself from screaming, terrible, terrible, it turned out that the slaughter in the era of cold weapons was so cruel, slaughtering 30,000 people at a time, and the whole process was completed in less than half an hour, his face turned pale, and the shock in his heart was revealed on his face.

There were also many prisoners of war who did not die, but were only wounded after being shot, and the Hun cavalry rode over and stepped on the corpses and began to clean up the corpses with spears, but those who were not dead were all poked with another spear.

It took another half an hour to finish, the Hun cavalry got the order to start dismounting and throwing the corpses into the mass grave, two people carried one, the Hun iron cavalry had 50,000 people, leaving a part of the guard, and most of the other part carried the corpses, and in a quarter of an hour all the 30,000 corpses were thrown into the mass grave, and then began to fill the soil, ready-made shovels and baskets, tens of thousands of Huns worked together, and in less than half an hour, the deep pit where 30,000 people were buried was filled, and nothing could be seen after dealing with the scene.

As soon as the mass grave was filled, the funeral party went to the riverbank, and the slaves carried Attila's body down the wagon, walked down the riverbed, and walked into the underground tomb under the instructions of a special person, while the remaining slave soldiers, under the order of Onigseus, laid down their weapons and began to carry large boxes that had been placed on the riverbank into the tomb.

Qin Dong saw those big boxes being moved into the tomb, and immediately understood, it turned out that those big boxes that had been placed on the river bank and piled up like a hill contained all gold and silver treasures and precious stones, how much did this cost, Attila has been robbing from the Eastern and Western Roman Empires, not only robbing, but he also wants two Roman Empire tributes, and the gold and silver treasures accumulated in the past twenty years are almost immeasurable.

The 50,000 Hun cavalry here had no idea that Attila's body was being sent, they were only ordered to supervise the construction of underground fortifications for 30,000 prisoners of war, of course, the construction of underground fortifications was supervised by special construction engineers, and after the completion of the works, their task was to kill all those who entered the underground fortifications.

When all the gold and silver treasures that accompanied the burial were moved into the underground palace, Qin Dong saw that the chief confidential secretary Onigseus took all the slaves and slave soldiers who were buried together into the underground palace, and it didn't take long for smoke to rise from the entrance of the underground palace, and then, the entrance door was closed from the inside of the underground palace, but Onigseus did not come out.

After the entrance gate was closed, a small group of Hun cavalry jumped down from the horse and picked up a shovel to rush to the entrance gate to fill the entire entrance gate with mud, only a quarter of an hour, the entrance black hole was gone, the gate was gone, and there was only a layer of freshly paved river sand on the riverbed.

Onigseus guarded the secrets of Attila's graveyard with his own life, and no one ever knew where Attila's graveyard was, what vicious traps were inside, and the Hun cavalry had no idea what mission they had just performed.

The trumpets sounded again, and smoke billowed from the lookout on one side of the riverbank, and the Hun cavalry began to withdraw from the riverbed in an orderly manner, and there was nothing on the riverbed except for a few signs of people moving near it.

After a while, the 50,000 Hun iron cavalry withdrew cleanly, only the fire on the lookout was still burning, and smoke was still rising, and smoke was also rising on a hill in the distance.

Qin Dong got up and threw away the grass camouflage on his body, and ran quickly towards the riverbed, he wanted to go to the scene to see, to see the huge mass grave, to see the entrance to the cemetery of the Xiongnu King, who once shocked the world.

The riverbed was soft, but the more mud got to the middle of the riverbed, Qin Dong stood in a clearing full of river sand, and at his feet was a huge mass grave, where 30,000 prisoners of war were buried, most of them were shot, and the other part was buried alive.

Qin Dong even felt a chill coming from under his feet, and there were even countless mournful wails echoing in his ears, he knew that this was a psychological factor, although he had been living a life of licking blood from the knife in his previous life, but he had never seen such a big scene, he was a little uncomfortable psychologically, and it was very good that he didn't vomit on the spot.

"Roar-" Qin Dong drew his knife and dispelled the fear in his heart out of thin air, and then walked to the entrance of the cemetery with the knife, he didn't know if any of the slaves who were locked up in the cemetery still hadn't died, but there was no doubt that these people couldn't come out of it again, they could only die inside, the entrance to the cemetery had been sealed, and smoke came out before it was sealed, indicating that Onigseus had put smoke inside, or poisonous smoke, in short, the people who were locked in it were dead!

Time is really ruthless, it can erase the traces of any person's existence, no matter how great the person has created, in front of the pig-killing knife of time, no one and everything can resist its cutting.

Just as he was sighing, Qin Dong seemed to hear a huge roar, he came to his senses, what kind of sound is this? He turned his head to look at the source of the voice, only to see his eyes freeze, and his face instantly turned pale.

A white line appeared at the bend of the riverbed in the distance, it was a monstrous wave, hundreds of millions of tons of river water seemed to be surging from the sky, Qin Dong instantly understood, it turned out that the upper section of the Danube River had already been dammed by the Hun army to intercept the river, no wonder the Danube River would dry up, and the beacon fire message on the lookout next to the river bank was to inform the upstream army to dig the dam and release the river water.

Run! Qin Dong reacted immediately, and Sa Yazi ran desperately towards the river bank, he had to go ashore before the river rushed over, otherwise he would wait to be washed away by the huge waves to the unknown other side, and whether he died or lived was all up to the will of heaven.

The surging river rushed over and made a rolling thunderous sound, the momentum was huge, Qin Dong was so frightened that he was scared, running, running desperately, Qin Dong used all the strength of his body to rush to the river bank, before he ran out of strength, he finally ran to the river bank, and at this time the river just rushed over, only a few seconds later he will be washed away, for which Qin Dong is very happy.

Seeing that the river was flowing again, and Attila's cemetery and the 30,000-person giant pit were covered by the raging river below, Qin Dong finally knew why, after more than 1,500 years, people still did not find the reason why Attila's tomb was still not discovered, because even if there were tomb robbers who got sporadic news, they could not go to the tomb, which tomb robber had the ability to build another dam on the Danube?

Qin Dong got up in shock, patted the sand on his body, rubbed his pale face, glanced at the river again, and turned around and walked towards the woods.
