After digging out its core, Tang Yu found that the core of the second-order Zerg was larger than that of the first-order Zerg, the size of an egg.

He then proceeded to send its corpse into the decomposition system......

Give the disassembly command, and soon the system prompt will sound in your ears.

"Ding, decompose completely, gain energy points, twenty points."

"Twenty?"

Hearing this number, Tang Yu was overjoyed.

Unexpectedly, the corpse of a second-order zerg brought four times the income of energy value compared to a first-order zerg.

At this time, his energy value had reached as much as five hundred and seventeen points.

After doing all this, Tang Yu teleported back to the Hero Fortress.

"Master, why are you injured again?"

Little Lori asked with a frown.

"Wait, I've got to heal my wounds first."

Now that he's still wounded, it's clearly not the time to speak. Without hesitation, he directly activated the medical system, passed through the portal, and entered the medical room.

After entering the medical room, Tang Yu didn't have to take care of the rest.

Because, without his instructions, the medical system will treat all the injuries in his body at once in the default form, leaving no hidden dangers.

began to heal, and a spray sprayed on Tang Yu's face, instantly making him unconscious.

I don't know how long it took, but when he woke up again, his injuries had healed.

This time the healing, because the injury was not serious, only cost three energy points.

Back in the control room, Tang Yu asked Xiao Lori.

"Why didn't the Advanced Life Detector find the second-order Zerg that sneaked up on me?"

It was because the Advanced Life Detector did not show it that he let his guard down. If he hadn't reacted quickly, I'm afraid he would have died by now. So he naturally wanted to ask clearly, maybe it was the failure of the Advanced Life Detector, which was related to his own safety, so he naturally had to ask clearly.

Little Lori heard this and explained.

"Master, your Advanced Life Detector is only Level 1 now, so it can only detect First-Order Zerg within a radius of five hundred meters around. Zerg beyond this level will not be able to be detected by the Advanced Life Detector. ”

was explained by her like this, Tang Yu was suddenly stunned.

It turned out that the level of the Advanced Life Detector was too low.

"Is there any solution to that?"

Tang Yu asked.

"Yes."

Little Lori nodded and said.

"As long as the Advanced Life Detector is upgraded to the enhanced version, the second-order Zerg within five hundred meters can be discovered."

"What about the Third Order?"

Tang Yu asked again.

The woman who saved his life said that there were third-order zergs in this deep mountain and old forest, and one of them was remembered by him, and the third-order zerg was enough to kill his existence in seconds, so he naturally had to prepare some means to prevent it. Don't die then, you don't know how.

"The third-order zerg can't do it, unless the master upgrades the hero fortress and upgrades the advanced life detector to the super life detector."

Little Lori explained.

"Oh, alas. It seems that the only way to strengthen the Advanced Life Detector is to do so first. ”

Tang Yu sighed helplessly.

For fifty energy points, the Advanced Life Detector was upgraded to an enhanced version.

Holding the enhanced version of the Advanced Life Detector in his hand, Tang Yu took a closer look and found that the overall appearance had not changed, it should only be that the function had changed.

After upgrading the Advanced Life Detector, Tang Yu finally breathed a sigh of relief.

At least for now, he didn't have to worry about a second-order Zerg being able to sneak up on him without the gods knowing.

As for the stronger third-order zerg, there is no need to worry too much.

Because, although the third-order zerg is strong, the good thing is that there are few of them. After all, Huaxia is not the main battlefield where the two races of humans and insects are fighting, and there are not many high-level zergs in the country.

By the time Tang Yu returned to Earth with all the equipment, it was already dark.

"It's time to leave."

Tang Yu looked at the pitch-black, quiet old forest in front of him, and muttered to himself.

Riding a motorcycle and bringing a night vision device, Tang Yu embarked on a journey home.

From time to time, he glanced down at the enhanced version of the life detector, and suddenly, Tang Yu's eyes froze.

Because, on the Advanced Life Detector, Tang Yu saw a flickering green dot.

The first-order zerg is a red dot, so could the green dot be a second-order zerg?

Thinking of this possibility, Tang Yu drove up at full speed and accelerated away.

If you don't run, you can't do it, the second-order zerg is only a hundred meters away from him, and if you don't run, if you are discovered, you won't be able to run away. He wasn't sure how to deal with the second-order Zerg right now.

The black lightning accelerated, and half an hour later, Tang Yu left the deep mountains and old forests where he had spent five days.

"I'll be back!"

Tang Yu glanced back and muttered to himself.

When he comes back, he will definitely not be afraid of the second-order zerg again.

Along the way, Tang Yu found a lot of Zerg figures from the Advanced Life Detector. But he didn't do it, because it would be a waste of time, and he hurried back.

It took only five hours to rush at full speed, and at about two o'clock in the morning, he finally saw the slums under the walls of the northern city of Nanhai City.

"It's finally back!"

Tang Yu breathed a sigh of relief and unconsciously relaxed.

When hunting, even with the Advanced Life Detector in hand, he did not completely relax his vigilance, but always kept an eye on it, otherwise it would be impossible for him to avoid the sneak attack of the second-order Zerg.

And the price of doing so is that he is mentally tired and needs to relax.

Before returning home, Tang Yu helped the black lightning into the house and closed the door. Immediately rushed into the bathroom.

He had been out for six days, had not taken a shower, and now it was summer, and the strange smell on his body was almost unbearable even for himself.

This bath, after an hour of washing and rubbing several times, Tang Yu felt cleaner.

Drying the water and changing into clean clothes, Tang Yu walked out of the bathroom, and suddenly felt a lot refreshed.

"Get a good night's sleep, get things done tomorrow, and start school the day after tomorrow!"

Tang Yu thought, then walked back to the room, collapsed on his big bed and fell asleep.

I have to say that sleeping in a bed is much more comfortable than sleeping in a sleeping bag.

This sleep, Tang Yu slept directly until noon the next day.

Tang Yu opened the curtain with sleepy eyes, looked at the scorching sun, the dazzling sunlight came over, suddenly narrowed his eyes, put the curtain down, and muttered.

"It's noon!"

Then, he didn't procrastinate, got up and washed, and went out.

When he went out, he still carried a large sack on his shoulder, which was swollen and looked like it was filled with a lot of things.

That's right, inside are the one hundred and three first-order worm cores, and one second-order worm core.

He's out now, intending to sell these worm cores.

After all, the cash he had left on him now was only about 1,000 yuan, and if he didn't sell these worm cores, he would soon be so poor that he couldn't even afford to eat.
