This time it took a bit longer; after the experience was maxed out, Wang Jiahui herself upgraded the collection axe to level three. The collection speed became three times faster, and the speed of obtaining by-products also increased.
"Now the axe is already at tier three, but I'm happy today. If you're not in a hurry, you can continue cutting trees, I can directly help you upgrade to tier four," Yang Yuan said.
"Tier four..."
Wang Jiahui's eyes lit up: "Will it cost extra?"
"No need." Yang Yuan shook his head.
"Thank you."
Wang Jiahui was delighted and was about to continue cutting trees when she realized her space backpack was full.
"Um... I might need to go back and put the wood away, my space backpack is full," she said.
Yang Yuan smiled and said, "Is wood more important than marvels? Why not just throw it away?"
"It's not that; I just feel it's a waste to throw it away."
