0177: Emergency
"Insufficient resources required for upgrading, upgrade failed!"
The crisp voice of the system poured down on Cao Qingtian like a basin of cold water.
"I was so excited that I forgot about this!"
As soon as he saw the progress was full, he subconsciously upgraded the city. With the prompt of the system, Cao Qingtian realized that there were not many resources left.
Cao Qingtian was very eager to upgrade the city, although he could now use gold coins to buy some basic resource packages in the alliance store to upgrade the city.
The price of the basic resource package was not expensive for Cao Qingtian, and it could even be said to be very cheap.
But Cao Qingtian still gave up buying basic resources in the alliance store.
Because he always felt that gold coins would play a greater role in the later stage, and it felt a bit of a loss to consume them in the alliance store.
And for Cao Qingtian, there are too many ways to obtain resources, and the premium of intermediate resources at this stage is serious.
Cao Qingtian soon had an idea.
So, Cao Qingtian opened the trading channel, and the first step was to filter, directly filtering out the trading needs of intermediate resources.
"Ten units of stone, please exchange for one unit of iron ore!"
"Twenty units of stone, please exchange for one unit of Xihai wood!"
"Fifty units of stone, please exchange for one unit of rosewood!"
"One thousand units of stone, please exchange for one unit of Xishan jade!"
"Two thousand units of stone, please exchange for one unit of Xishan jade!"
"Ten thousand units of stone, please exchange for one unit of black gold ore!"
At this stage, stone has become hard currency. Among the basic resources, stone has the highest value. The most expensive food before is now the lowest value.
One unit of stone can be exchanged for two units of wood or five units of food.
The price difference in the intermediate resources is also astonishing.
The cheapest intermediate resource is iron ore, which can be exchanged for ten units of stone. The most expensive black gold ore can be exchanged for ten thousand units of stone, and it is still priceless!
"I have quite a bit of this iron ore."
There is a super miner Zhao Kaishan in Chaos City. The stones mined can be directly processed into iron ore, and a lot of iron ore was harvested when attacking Black Wind Mountain.
"Let's use the iron ore to exchange for basic resources."
Soon, Cao Qingtian exchanged enough basic resources for upgrading the city with iron ore on the trading channel.
As usual, the time was reduced by a hundred times.
"Just wait for the city to be upgraded. After the city is upgraded, there will be a rare building, the Bronze Sparrow Tower, to be built!"
Looking forward to Cao Qingtian.
Time passed by, and the residents who worked outside Chaos City also returned to Chaos City in groups.
The restaurant was filled with smoke, and the aroma of food filled the air.
After working hard for a day, eating delicious food, don't mention how comfortable it is.
Cao Qingtian took in everything with a smile on his face.
"Lord of the City."
Diao Chan came to Cao Qingtian's side without knowing when.
"What's the matter?"
"The news sent back by the scout is about Luo County."
"Go ahead."
Cao Qingtian had a bad feeling for a moment. If everything went well, he should have returned by now, but now the scout has sent back the news.
"The Yellow Turban Army and the Black Wind Mountain bandits in Luo County are in a stalemate. The two sides are on the verge of a fight, shouting and cursing back and forth, with thunder and rain but little rain. If this continues, the battle will not start."
Cao Qingtian frowned, and Diao Chan continued:
"The two sides are already like a powder keg, and only a fuse is needed to detonate. General Han has sent a message to the soldiers who sneaked into Black Wind Mountain earlier, looking for an opportunity to take action, ignite the conflict, and let the two sides fight."
Cao Qingtian nodded.
Since things have come to this point, we can't let both sides just talk nonsense without consuming their actual strength, right?
The home of Black Wind Mountain was stolen by Chaos City. If the bandits in Luo County knew this news, when the army marched to Chaos City, it would be a big trouble for Chaos City.
So Han Xin's idea was very simple. In Luo County, he would consume the strength of the Yellow Turban Army of Black Wind Mountain to the greatest extent. While the snipe and the clam fight, the fisherman will benefit.
"In addition, General Han also discovered a third party force besides Chaos City."
