Crack!

The electric light spread rapidly in the stagnant water and bounced between several gold coin monsters. The bright light snake jumped and made a violent friction sound with the air. The ground seemed to be ignited and covered with a layer of golden fireworks!

-30!-30!-30!

…

Dense numbers of damage rose, the lightning tower's attack speed was instantly increased to 0.5, and the attack speed was so fast that it was invisible to the naked eye.

Cheng Shen only saw,

In the statistics panel, its output data rises rapidly in a straight line!

The seventh one, the eighth one...

The tenth one!

When the one-minute time limit was reached, the last gold coin monster, which had faded and almost disappeared, was finally blasted to pieces on the road.

【Defense completed!】

[Obtain: 100 gold coins!]

…

"Perfection!"

Cheng Shen smiled with satisfaction and looked at the final statistics interface.

[Lightning Tower: dps171, total output 9778.]

[Wooden Arrow Tower: dps93, total output 5612.]

[Water Demon Tower: dps67, total output 4019.]

[Ice Arrow Tower: dps25, total output 1503.]

…

The total output of the four towers in one minute exceeded an astonishing 20,000.

The credit for this is definitely inseparable from the Energy-Gathering Tower. It is not that it initially strengthened the attack frequency of the Water Demon Tower and took the lead in creating an output environment conducive to the Lightning Tower. The damage of the Lightning Tower will definitely not be so high.

It can be said that two-thirds of the lightning tower's output should be attributed to the energy gathering tower and the water magic tower!

Cheng Shen never expected that the Water Demon Tower that he planned to train as the main tower would actually work wonders in the supporting role...

"The combination of defense towers is really important."

Cheng Shen thought to himself.

The combination of water flow and lightning can only be regarded as the most basic one.

He considered that it would be best to add a metal defense tower in the future to further utilize the performance of the lightning tower.

Of course, this depends on whether the system will give you face or not.

Got money.

Cheng Shen immediately started consuming.

Buy wood first.

He wasn't going to exchange it for other materials.

The first wave was driven by helplessness. Iron ingots, stones, and clay were all needed to upgrade the territory center.

If you exchange it, you will eventually have to buy it back.

The gain outweighs the loss.

"Collect gold coins to collect wood, a lot of it, message me privately with the ratio!"

Cheng Shen posted the transaction information.

Within two minutes, his communication began to flash frequently.

"25."

"27."

"29."

"35!"

…

It automatically filters out those with a ratio lower than 20.

Gold coins are very precious.

It is one of the indispensable requirements for upgrading buildings.

It can be said that it is the only scarce resource at this stage that can be compared with defense tower blueprints.

But there's a problem.

That is, the wood resources in the hands of survivors are not abundant now.

Cheng Shen's mental estimate was that one gold coin could be exchanged for at least fifty pieces of wood, but in reality no one could afford it.

The information is pulled to the end.

Cheng Shen chose to send a private message to the lord who bid 35.

"A little less."

he tried.

"The most I can give is one to forty...how much can you charge?"

The other party quickly replied.

"At least five hundred."

Cheng Shen thought for a while and said.

The wood required to upgrade the double wooden arrow tower has been increased to 50 units.

Upgrading to level four costs 200 wood.

In addition, there are also the consumption of fences, wooden stakes, and campfires. Cheng Shen has not even considered the upgrade needs of the territory center.

Upgrading the territory center requires 300 units of stone and wood each.

However, Cheng Shen felt that it was too early to expand the territory, so he did not take this demand into account.

"Do you want that much?"

The other party was a little surprised.

"In this case, I can give you one to forty-five, provided you have enough gold coins to eat it."

He replied again.

"make a deal."

Cheng Shen said happily. When the other party replied with the second sentence, he remembered that this was the lucky man who recruited a rare elf.

I think so.

except him,

I'm afraid no one can come up with so much wood now.

"500 wood, that's 11 gold for you... But I have to remind you, brother, you need gold coins to upgrade the building. I only traded with you because I was short of gold coins. I will not return it after the transaction is completed!"

Aoki reminded before the transaction was locked.

"I know."

Cheng Shen chuckled.

Being able to remind him to this point shows that Brother Aoki is not a bad person. If you were someone else, he wouldn't care about you. Only when you get the gold coins is it real.

certainly.

It does not rule out the possibility that he was testing.

At the end of the first wave, everyone will have at most ten gold coins in their hand.

Even if he gets an A rating, he is no exception.

The extra gold coin may be earned by selling materials, but if he can still use eleven gold coins to purchase supplies after upgrading the building, it only means that he has another way to make money.

As expected.

After the transaction was completed, Aoki couldn't help but asked: "I would like to ask, buddy, did you hit a gold coin scroll?"

"Um?"

Cheng Shen was surprised and then thought: "You also have one?"

"No. But by coincidence, a friend of mine happens to have one in his hand, and he is currently looking for information. So I want to make a deal with you, in exchange for a piece of information about the second wave of monsters, how about it?"
