You dare to cultivate without money?!

Tu Lishan looked at everyone and said, "You have 15 minutes to prepare next. Think carefully about what you should do next."

Zhang Yu looked at the blueprint floating in his eye socket. With a double-minded consciousness, he quickly constructed the layout of the blueprint in his mind.

"Is this... a bunker?"

Zhang Yu thought to himself, "The structure of the bunker itself can be used to resist various offensives."

"At the same time, it’s probably a hint, representing the tenfold attack upon completion, likely related to war."

Thinking about this, Zhang Yu sighed in his heart, "Another war element? It seems many in the Civil Engineering Department really think college wars will get bigger, to the point that exams continue to prepare for them."

Looking at the entire structure of the bunker and contemplating the key within it and his own advantages: "With my construction efficiency, finishing the bunker within three hours is no problem."

"The key is to push the strength of the bunker high enough to withstand more attacks and maintain higher integrity after offensives."

"What method can maximize my advantage?"

Just as Zhang Yu was deep in thought, Li Xiao looked at the blueprint in his eye socket, his eyes glowed sharply, and the answer was already in his heart.

"The key is materials."

Li Xiao thought to himself, "Use the highest quality materials to build the bunker. The better the materials, the higher the bunker’s strength. Even with the same construction efficiency, it’s doing more with less."
