Secondly, it is inconvenient to purchase and requires transportation back and forth, which is a waste of time.

So Zhou Zhou never thought about this aspect.

After that, he opened the exchange and looked at the current prices of basic materials.

I found that one Black Iron Grade Fog Heart can now be exchanged for 50 units of basic materials.

“The price is acceptable.”

"Then buy more at once."

Zhou Zhou thought for a moment.

There are quite a lot of basic materials required to build a city wall.

Prepare more and you won’t need to buy again in a short time.

Then he started setting up the trade.

[Transaction name: Sun Lord’s transaction]

[Trading goods: 8 million black iron-grade fog hearts]

[Trade requirement: Trade 1 Black Iron-level Mist Heart for every 50 units of basic materials.]

Setup completed.

Post transaction.

Then he set up a new transaction, threw in all the military class transfer certificates he had just obtained, as well as excess materials, skill books, equipment and other items, and then directly issued the transaction.

After a while.

The transaction to acquire materials was completed first.

Zhou Zhou took a look at the transaction results.

[Transaction results: 100 million units of stone, 100 million units of wood, 100 million units of metal, 100 million units of fine sand]

Zhou Zhou nodded.

Then he took Zhao Changshou to an open space, and then took out all 400 million units of basic materials and piled them into four hills of basic materials more than 20 meters high.

"These basic materials should be enough in a short time, right?"

Zhou Zhou smiled.

"It's really enough."

Zhao Changshou looked at these four hills with some smacking of tongue in cheek.

It's not like he had never seen the same scene before when he was in the Aurora Kingdom.

But he really hasn't seen many scenes like the lord, where he waved his hand and saw four hills of basic materials.

at this time.

Bai Yun came over after counting the number of soldiers promoted.

"Report to the lord!"

"A total of 5132 people have just been promoted!"

"3125 of them were promoted to Black Iron Intermediate and Black Iron Advanced!"

"1941 people were promoted from black iron level to bronze level!"

"Another 72 people have been promoted to the lower level of Silver!"

"Now our army has a total of 14,583 black iron-level soldiers!"

"2583 bronze-level soldiers!"

"98 people at the silver level!"

"In addition, my subordinates have now reached the silver level!"

"Maris has also broken through to the bronze level!"

Bai Yun said respectfully.

Zhou Zhou couldn't help but click his tongue when he heard this.
Chapter completed!
