Tang Yizhou did not check the harvest immediately, but quickly walked towards the corpse of a leader-level mechanical vulture next to him. After touching, he touched another leader-level.

At this point, including the leader-level mechanical vulture he touched before, his current gain is-

The upper limit of power is increased by 450 grids, and the current total limit is 2505 grids.

The Golden Energy Ball currently has 5, with a total of 11.

There is currently 1 white technology ball, and a total of 2 balls have been obtained.

The Blue Technology Ball currently has 58, with a total of 133.

The red detection ball currently has 7, with a total of 25. Because 11 were given to Zhang Xin before, it cannot be counted as the cumulative one.

A black unknown ball.

Overall, the conditions for unlocking the fourth layer permissions are still not enough.

I guess even if I give him all the spoils from this battle, I can't force it.

Next, Tang Yizhou signaled Zhang Xin to come and touch the two chiefs, Zhao Sanxing touched one chief, and Roland touched the other chiefs, as for the two ordinary levels, he touched it himself.

In addition, there were two mechanical vultures at the leader level, but they were all snatched, namely the Crow Sentinel snatched one and the Big Hei snatched one.

After they are grabbed, the benefits are naturally numerous, and you can view them through the mechanical attribute bar.

All of them have an additional 50 grids of power cap, and the golden energy ball and other blue industrial balls, and the red detection ball are strengthened all at once.

The Crow Sentinel was strengthened to metal value of 25 in one breath.

The mechanical wild dog big black was strengthened to a metal value of 18 in one breath, but it turned out to be 12.

But Dahei does not increase the evolution progress.

In short, although the mechanical vulture tribe has not been destroyed, it can definitely be considered a severe injury.

"Xiao Tang, you didn't unlock the fourth layer permission?"

Zhang Xin asked at this time.

"No, there are still 12 blue industrial balls and 25 red detection balls, this is not urgent." Tang Yizhou shook his head, "But there is one thing, bosses of this level will drop white technology balls, so I have enough of them."

"Oh, and I need to emphasize that the golden energy balls in your hands should be kept. After you have enough two, you will use them to create reinforced mechanical wild dogs or reinforced mechanical spiders. These are all required for team building. Mechanical wild dogs can serve as patrol guards, and carts can be pulled, and spider engineers can make mechanical spider silk. In principle, each member must have a mechanical wild dog and a spider engineer."

"Now, clean up the mess. We lost a total of 52 pairs of energy-saving wings and eighteen spider heavy crossbows. This painful lesson tells us that our base car is not strong enough."

Next, Tang Yizhou let the crow sentry take off, Xiao Zhao's Dahei patrolled around, and the rest gathered the spoils together.

It mainly cuts the wings of mechanical vultures, because these wings can also convert electricity.

The specific standard is that the storage limit for ordinary mechanical vulture wings is 20 grids, the storage limit for leader-level mechanical vulture wings is 80 grids, and the storage limit for clan leader-level mechanical wings is at least 500 grids.

In this regard, the gains are far greater than the losses, because with these gains, the team's daily power revenue has even exceeded 2,200 units.

The lost energy storage wings cannot be remade into energy storage wings because the metal is not worth enough, unless it is strengthened with a blue industrial ball, but it is a bit unworthy of the loss. So it is better to make more mechanical spider silk as food for mechanical spiders.

This time, the complete destruction of the mechanical vulture was also made Tang Yizhou learn from his mistakes. He must accumulate enough mechanical spider silk to wove it into a defensive net. After all, the base car was built for use, not for destruction.

After giving everything, Tang Yizhou was free to check the black unknown ball.

This was the first time he had seen a black ball, and he had never heard of anyone touching a black ball. Everyone learned about gold energy, blue industry, red exploration, and a white science.

So what does black mean?

With this idea, he stared at the black ball in the property bar. It was very lively, or it was simply a black vortex, constantly rolling and rotating.

After staring for almost three seconds, the answer came out.

Several lines of information appear in the mechanical properties bar.

"You got a black free kick."

"Using a black free kick, you can exchange for a purple attack ball, or two white technology balls, or four golden energy balls, or twenty red detection balls, or fifty blue industrial balls."

——

"Moon! So there are actually six kinds of small balls?"

Although Tang Yizhou was shocked, this was the first thing he thought of.

Moreover, through this exchange ratio, it can be seen that purple attack balls are the rarest, white technology balls are the second, golden energy balls are the third, red detection balls are the fourth, and blue industrial balls are the most common.

As for the black free kick, it is not in the cycle for the time being.

"So, how should I exchange it?" Tang Yizhou fell into deep thought.

Logically speaking, the reaction of a normal person must be exchanged for a purple attack ball, after all, the rarest, and the reason why the clan leader-level mechanical vulture is so powerful is mostly related to the attack ball.

But he thought about it a little more.

That is, he will soon open the fourth layer permissions in the mechanical attribute bar, and then he will know what conditions are required to enable the fifth layer permissions.

What if one of the permissions to turn on the fifth level is to have a black free kick?

So it's better to keep it first.

If one of the permissions to open the fifth level is to have a purple attack ball or something else, then he can naturally redeem it.

This is a safe solution.

Thinking of this, Tang Yizhou put the black free kick on the shelf, and then he took a look at the five golden energy balls he currently has. He did not reveal that he had touched the five golden energy balls, which was also a bit of self-protection.

Two of the golden energy balls must be taken out to create a mechanical wild dog, and one is reserved for backup.

The remaining two...

He hesitated for a long time and finally assigned it to the energy storage skills, upgrading the second-level energy storage to the third-level energy storage. Although he has many energy storage wings, due to uncertainty about the future and lack of security, he still needs to upgrade this skill as much as possible.

The specific description is - standing in the sun, you can speed up the conversion of life electricity, convert 4 grids of electricity per hour, and at the same time, reduce your own power consumption by 30%, and the impact of the external environment on yourself -10%

After reading this description, Tang Yizhou couldn't help but breathe a sigh of relief. In fact, he was really distressed to directly allocate two golden energy balls on it, because now he really does not lack electricity. Is so many energy storage wings not good?

As a result, it turns out that no skills are useless.

This level 3 energy storage is very awesome.

Maybe it doesn't feel it when the upper limit of the battery is not high enough, but the current upper limit of the battery in Tang Yizhou is 2505 grids. The power of eight people is equivalent to eating food from eight people a day. If he doesn't eat food, he will consume 100 grids of electricity every day.

Just exercise and start with two hundred grids.

This is scary.

But with this third-level energy storage, everything will turn into spring and rain, and the sun will be shining brightly.

It's so comfortable to directly reduce the consumption by about one-third.

Finally, the impact of the external environment on oneself is reduced by 10%, which is also very awesome. For example, in the cold winter, this is a strict external environment.

So at this moment, Tang Yizhou has decided to at least upgrade to level 5 energy storage, which means 12 golden energy balls are needed.

That's it...
Chapter completed!
