Lang Yun felt somewhat excited in his heart. Over the past week, Lang Yun had accumulated quite a lot of contributions. Although he was still far from the twenty thousand contributions needed to exchange for a four-star mechanical weapon, he hadn't seen the actual items on the exchange list before, which always left him a bit worried.
Now, seeing these mechanical creations being manufactured put his mind at ease. He was left with one thought: to work hard for the Sanctuary and accumulate contributions as soon as possible. Others who came with Lang Yun had the same idea in their hearts.
Then Lang Yun saw that Yu Ping'an was still standing at the door.
At that moment, Lang Yun said, "What are you standing there for? The Administrator wants you to go in."
Hearing this, Yu Ping'an no longer hesitated and walked into the courtyard.
"Is it you who offered the drawings of the Water Cultivation System and the transport crawler, just to see me?"
