[Stone City Wall Construction Drawing: After use, an 8-meter-high stone city wall can be automatically built. The required building materials and construction time depend on the construction perimeter of the stone city wall.]

This is even rarer than the architectural drawings of residential buildings.

"There are quite a lot of European emperors from the Dragon Kingdom. It's only the second day that someone has obtained such a prop."

Tang Jing was a little jealous.

The seller's name is Liu Hong, and he should also know the value of the "Stone City Wall Architectural Drawings". The auction is for bidding, with no reserve price and no deadline.

At first glance, it looks like it is used for fishing, or simply for showing off.

Tang Jing didn't care so much and immediately chatted with Liu Hong privately through the market and expressed his intention to buy.

"This is not cheap. To tell you the truth, the highest quotation has reached 10,000 units of stone. I haven't even sold this." Between his words, Liu Hong couldn't hide his pride.

Because of this drawing, he was exposed in family groups and classmates, which was when he was most proud.

"You will definitely be satisfied with my quotation." Tang Jing was confident.

"Are you bragging?"

Liu Hong felt a little unhappy, "I see a lot of big talkers like you."

"How about one level 1 crystal core?"

"Wha, what?"

Opposite Liu Hong, his eyes almost popped out of his head, and he said hurriedly: "Brother, it's a deal!"

After obtaining the architectural drawings of the stone city wall, Liu Hong became the focus of the family's training. There was actually no shortage of basic materials such as wood and stone.

At least enough for an upgrade.

Even if he is a refugee, his family members will willingly give him five.

But even with ten refugees, Liu Hong ventured out in the morning and did kill four or five wild wolves, but he still failed to obtain a level 1 crystal core and lost two refugees.

I guess my luck has been exhausted.

In this way, it is not difficult to understand how much Liu Hong desires level 1 crystal nuclei.

Where do you dare to hold it?
