Chapter 247 : Priceless

At Ye Tian's feet lay an ancient metal sword case, about one and a half meters long. When he held it in his hand, it felt like it weighed over a hundred kilograms! The surface of the sword case was adorned with intricate patterns, resembling some kind of runes. Setting the sword case aside, he examined the other boxes. Ye Tian opened one of them and found twenty large volumes of books neatly stacked inside. He carefully read the title on the cover, "Yongle Encyclopedia," a total of 3,720 volumes!
