The magic model that Lucien needed to build was called Star Shield. Thankfully, Lucien already practiced constructing the model multiple times in the past, so he remembered clearly how the model was divided, how long the lines were, and how the lines were connected to each other. All he needed to do now was stay calm.
When he was concentrating on the magic model, Lucien noticed that his spiritual power was being consumed very fast. By the time he finished one-third of the work, he found that there was only half of his spiritual power remaining.
"You gotta make the best use of your spiritual power." Lucien talked to himself in his mind. Building a magic model was like drawing a complicated pattern on a piece of paper using a pen, but with a very limited amount of ink. To save the resource, the person drawing the picture needed to stay very calm, to prevent the hand holding the pen from trembling too much.
