Shen Cheng and Shi Yu entered the main building and, after circumventing the lobby, found the staircase. The staircase had a spiral design and was made of Phoebe wood.
Phoebe wood, also known as Phoebe, is divided into several types including golden silk Phoebe, fragrant Phoebe, and water Phoebe. These types of Phoebe wood are extremely hard.
The staircase here was made of fragrant Phoebe, which is costly and often used for shipbuilding and palaces.
Fragrant Phoebe is extremely precious and has been listed under national key protected wild plants.
Shen Cheng was very familiar with Phoebe wood because she had given a presentation on Phoebe wood during her school days, so she knew its importance very well.
It was indeed a place where emperors used to live, so using fragrant Phoebe for construction was not surprising.
"I can go up alone, you wait for me here."
Thinking that it might be inconvenient for Shi Keke, Shen Cheng decided to go up alone.
