"According to the regulations, this kind of worm core, in our store, is priced at five hundred earth coins, and we will buy it at this price, do you have any objections?"

The shopkeeper asked Tang Yu tentatively.

"No, five hundred is five hundred."

Tang Yu smiled.

He was already very satisfied with the price, so naturally he had no objections.

The two worm cores were sold to the pharmacy, and Tang Yu obtained a thousand earth coins.

This is a lot of wealth for him, who still lives in the slums.

"It seems that the road of selling worm cores to make money may really work."

Tang Yu thought to himself, and then returned home.

As soon as he got home, he immediately teleported to the Hero Fortress.

To hunt the Zerg, there are still many problems to be solved, and if these problems are not solved, he wants to make money by selling worm cores, which is very difficult.

And the solution, Tang Yu wants to see if he can find it in the Hero Fortress.

Reaching out to hug the little Lori who rushed over, Tang Yu asked her.

"In the Hero Fortress, is there an instrument like a radar that can detect the traces of nearby Zerg?"

This is the most critical point in hunting the Zerg and obtaining the Worm Nucleus.

Because if you want to hunt Zerg, you must first find them.

But in the vast wilderness, if you want to find the Zerg, how easy is it?

What's more, you have to find a lonely Zerg. After all, if it was a swarm of insects, with Tang Yu's current strength, it would be an act of sending them to death.

"Yes."

Lori nodded, then turned her head to face the screen and gave a command.

"Exchange system, classification, radar detection class, item, advanced life detector."

Little Lori's voice fell, and on the huge crystal screen, the page kept jumping, and when it stopped, there was only one item left on the page.

This item is the high-level life detector that Lori said in her mouth.

See the introduction.

Function description: This item can find the specific location of all higher life forms within a radius of 500 meters.

The so-called higher life naturally refers to the existence of ordinary life, such as the Zerg!

"It's only 500 meters, is there a larger instrument?"

Tang Yu asked Little Lori.

In his opinion, the radius is five hundred meters, which is a little smaller.

"Nope! Hero Fortress is currently in its first phase, and the exchange system can only redeem Level 1 items. If you are the master, you can upgrade the Heroic Fortress to the second stage. Then the Advanced Life Detector can be upgraded, and the range will be increased. ”

"In that case, we can only use it on point."

Tang Yu sighed.

Still, something is better than nothing, and he decided to redeem it anyway.

Looking at the energy value, it takes five points to redeem, which is not much. Therefore, Tang Yu did not hesitate at all, and immediately issued an exchange order.

Then, Tang Yu saw that in the wellhead, a palm-sized circular instrument slowly rose.

At the same time, in the upper right corner of the screen, the number twenty-three was also reduced to eighteen in an instant.

"This is the Advanced Life Detector."

Tang Yu played with the instrument in his hand and talked to himself with interest.

Palm-sized, round, about a centimeter thick, very small and easy to carry.

On the front, there is a whole screen, Tang Yu looked at it all, and only found a small button on the side.

Looking at the instruction manual displayed on the large screen in front of me, it turns out that this button is the switch.

This Advanced Life Detector is very simple to use, as long as you press the switch, all the advanced life in the range will show the location on the screen.

"Not bad."

Tang Yu nodded and carefully put it away.

For this advanced life detector, except for the detection range is a little smaller, he is very satisfied with all other aspects.

He then turned his attention to weapons systems.

If you want to go into the wild to hunt the Zerg, you need to have a weapon at hand.

In terms of his current strength, and the strength of his opponent, that family heirloom machete was enough for him to use for a while.

Melee weapons are available, but a ranged weapon is missing.

If you have a ranged weapon in hand, you can snipe the Zerg from a distance, which is much safer. So Tang Yu is now planning to activate the weapon system and exchange it for a long-range weapon.

"Activate the weapon system."

This time, without passing Xiao Lori, Tang Yu directly gave instructions as the owner of the Hero Fortress.

"Yes, the weapon system is activating!"

An icy chime came.

"Ding, the weapon system is activated, energy consumption value, ten points!"

In the upper right corner, the number eighteen is rapidly reduced to eight.

When the weapon system is activated, the large screen automatically switches to the weapon system page.

On the page, there are two options.

They are, cold weapons, and hot weapons.

Tang Yu is no stranger to these two words.

The so-called cold weapon is derived from the ancient swords, guns, swords, halberds, and forks.

And hot weapons, naturally, are guns and cannons in the scientific and technological society.

Tang Yu looked at it and chose the hot weapon without the slightest hesitation.

As a modern person, Tang Yu naturally subconsciously believes that the power of hot weapons is greater than that of cold weapons.

After all, no matter how powerful your knife is, can you compare it to a cannon?

The page turned to the hot weapon page, and when I looked at it, there was only one option.

Firearms!

Firearms, generally referred to as all kinds of firearms.

Seeing this, Tang Yu couldn't help frowning and asked Xiao Lori.

"Isn't it true that there are only firearms in hot weapons, and there are no aircraft cannons?"

It stands to reason that aircraft, artillery, tanks, missiles, these should all belong to thermal weapons.

In that case, why not here?

Tang Yu doesn't believe it, with such a powerful high-tech fortress as Hero Fortress, there will be no such things?

Hearing this, Lori explained.

"The thermal weapons of the first-class weapon system, only firearms. As for the aircraft cannon you mentioned, it may only be available after the system is upgraded. ”

"I see."

Tang Yu suddenly understood.

"Choose a firearm."

Tang Yu gave the order.

page to the Firearms page.

Looking at it, as Tang Yu expected before, there were all kinds of guns in the firearms classification.

There are pistols, rifles, machine guns, sniper rifles, everything is here.

According to the introduction, Tang Yu looked at them one by one.

In half an hour, Tang Yu saw a total of nearly 100 kinds of guns.

It's just that what left him speechless was that these guns, the cheapest pistols, also needed ten energy points to produce.

But now he only has eight energy points left in his hand.

Tang Yu, who looked helpless, exited the hot weapon page and chose the cold weapon page.

Melee weapons, ranged weapons!

Two options appeared in front of Tang Yu's eyes.

The melee weapons of cold weapons are nothing more than swords, guns, swords, halberds, forks and the like.

As for long-range weapons, the only things Tang Yu could think of were bows and crossbows.

If you don't have a gun, you might as well have a bow or crossbow!

Tang Yu thought helplessly in his heart.

Unexpectedly, in today's era of advanced technology. He also wants to hunt like humans in ancient times, and he actually uses primitive weapons such as bows and arrows......

Select the Ranged Weapons page.

Sure enough, at a glance, it was all bows and crossbows.

The difference is that depending on the amount of power, the amount of energy required varies.

Take a closer look.

Tang Yu tragically discovered that the energy value in his hand was only enough to produce a lowest-level hunter's hand crossbow......
