That night, except for Tang Yizhou, the other three tossed and turned, and it was difficult to fall asleep.

But in fact, even if they are worried about the country and the people, they have no use. This is the worst, and the weak have no say.

Before dawn the next day, Tang Yizhou replenished the power of the Crow Sentinel and the Wild Dog Captain, and also replenished the power of himself.

"You are pretending to be a good deal for the base car today, just wait here, and put the energy-accumulating wings out at the same time. Don't be careless, of course, don't worry too much. At present, with the destruction of the mechanical vulture tribe in this area, and with the unification of the mechanical black ant tribe in the south, it is still very likely that a new and powerful mechanical tribe will emerge."

Tang Yizhou ordered, and then rode the wild dog captain Dazhuang and continued to wash with the crow sentry.

In fact, today's Crow Sentinel is much stronger than yesterday. The power limit alone has exceeded 1,000 grids, the metal value has been strengthened to 27, and the evolution progress bar is 30.28%.

Then for some reason, maybe it reached the upper limit, but it stopped breaking through, but the benefits of hunting mechanical flying ants were transferred to Tang Yizhou.

So yesterday afternoon, Tang Yizhou actually obtained the upper limit of 550 grids, as well as 120 blue industrial ball fragments and 40 red detection ball fragments.

Don't ask how these fragments come from, he doesn't know either.

He only knew that 10 pieces could merge one, so he got 12 blue industrial balls and 4 red detection balls yesterday.

It was a surprise.

So if it is not unexpected today, he should be able to unlock the fourth layer permissions.

Continue to move south, about twenty kilometers south of Spider Town, Tang Yizhou encountered mechanical flying ants still marching. As expected, these guys marched overnight, and the number of mobile ant nests increased to twelve. From a distance, there are more mobile ant nests behind them. Just this scale is not an exaggeration to say that there are millions or even tens of millions of mechanical black ants.

From the air, the entire ground seemed to be covered with black oil.

There is no need to say that this is the strongest regional overlord of the year.

Tang Yizhou decisively controlled the crow sentry to move forward. The expansion of the mechanical black ant tribe was irreversible, but it did not delay him from taking some bonuses and gaining some experience.

The Crow Sentinel's speed is obviously a bit fast today because of the surging power, but Tang Yizhou still controls the speed appropriately and tries to the same as yesterday, so as not to reveal new flight information to the mechanical ants.

"call!"

The black curtain was pulled up, and hundreds of thousands of mechanical flying ants flew up bravely, but they were destined to be futile. The crow sentry could kill hundreds of them just by sweeping through the edge.

Well, I'm so skillful. In the battle that day yesterday, it was not just the crow sentry that made progress. Tang Yizhou also knew the flight data of mechanical flying ants well, especially the changes in the mechanical flying ants cluster, which could tell the clues at a glance.

In particular, the metal value of the Crow Sentinel has been strengthened to 27, which means stronger lethality. The sharp claws can kill a large piece of it with just a swipe.

However, Tang Yizhou still controlled that even a mechanical flying ant would not let the crow sentry pounce on it, and it would leave as soon as it touched.

It's nothing wrong to be cautious.

But even so, the killing efficiency has doubled compared to yesterday, and the experience value has increased rapidly.

One piece of industrial ball fragment after another, the detection ball fragments condense, form, and are automatically merged in the property bar.

This thing is magical. It is said that it is nothing. It can be taken out directly with your hands, which makes it feel numb when touched.

It's just that it's substantial, but it can still be transmitted from a long distance, just like a data stream, but it's very magical.

The crow sentries here are killing, and the progress of the mechanical black ant legion has not stopped. They are always like waves, advancing forward wave after wave, as if nothing can be stopped.

Tang Yizhou is very curious about what changes will happen when they encounter the mechanical spider group?

"There is a high probability that I will evolve the long-range attack method. Speaking of which, I have helped the mechanical spider, which uses the crow sentry to stimulate the mechanical black ants, so that they can concentrate resources to evolve the sky units with stronger evolution. When they encounter the mechanical spider next, they may evolve the long-range attack method later."

"Hehe, why do you have the illusion of Godzilla vs. King Kong?"

Tang Yizhou was full of thoughts here and his income was also gratifying. He just rewatched the whole morning and retreated. Finally, at 1:30 noon, when the evolutionary progress bar of the Crow Sentinel broke through to 49.97%, Tang Yizhou got the upper limit of 650 meters and successfully gathered the blue industrial ball and the red detection ball.

At this point, he has met the conditions to enable the fourth layer of the mechanical attribute column, that is,

Golden energy ball 10/10, blue industrial ball 150/150, red detection ball 50/50, white technology ball 1/1.

At this moment, deep in his mind, the mechanical attribute bar was running in full swing again, like an ancient and extraordinary mechanical device, making a rumbling sound, as if it was about to open a new world.

The whole process lasted for thirty seconds. Tang Yizhou felt that he seemed to have seen everything, but he seemed to have seen nothing. The mechanical attribute bar, which originally had very punk aesthetics, suddenly became ethereal. In addition to the gears of various mechanical parts, there was a galaxy data stream...

It's really a data stream, although he doesn't understand at all.

But this may also mean that the machinery and data flow are also inseparable?

don't know.

At this time, when the change of the mechanical attribute bar stops, the stream of data as brilliant as the Milky Way disappears, the attribute bar that appears in front of him has an additional change, that is, several lights are changing rhythmically, flickering light and dark, as if sending some signal.

In addition, there is an additional light, white visible light, which should represent a white tech ball.

At this time, the four rays of light intertwined brightly and dimly, just like a Moss code. After conveying some information, the four rays of light merged together again, forming a illusion that made Tang Yizhou very excited.

That's right, it's the wreckage of machinery everywhere, twisted, torn, rusted, broken, melted, and in short, it's an incomprehensible epic mechanical battlefield.

But it doesn't matter if you can't understand, because you can get the relics of mechanical wars from it.

After all, during this period, he had participated in and dominated the demise of the mechanical black bird tribe, severely damaged the mechanical vulture tribe, and once again severely damaged the mechanical spider tribe. Then the conditions for a war fantasy are met.

This time, the duration of this mechanical war illusion was extended for a second, then disappeared, and then, messages appeared in the mechanical attribute bar...

"You have obtained a total of 11/10 golden energy balls, 150/150 blue industrial balls, 50/50 red detection balls, and 2/1 white technology balls. You have unlocked the fourth layer of the mechanical key and received a reward. Your life power limit will be permanently increased by 100 grids, and you will get a blue mechanical creation drawing, and a random reward for the black iron-level mechanical war relics (click to view details)."

——Mechanical War Relics (Black Iron Level), indicating that when the mechanical key holder personally causes fatal damage to two or more mechanical groups (annihilation of the mechanical wild dog group, severely damage the mechanical spider group, destroy the mechanical black bird group, and destroy the mechanical vulture group), and at the same time, it will have a certain chance of obtaining it. Mechanical War Relics can be used to exchange for more advanced mechanical creation drawings, and can also be directly integrated with yourself. Friendly reminders, your choice determines your destiny.

"Because you have enabled the fourth level of permission, you will get a free friend prompt - you will get a total of 30/30 golden energy balls, a total of 500/500 blue industrial balls, a total of 150/150 red detection balls, a total of 3/3 white technology balls, a total of 1/1 purple attack balls, a total of 1/1 purple attack balls, a fourth level of permission of the mechanical key will be opened, and a reward will be obtained, a red mechanical creation drawing."

"Note: After the permissions are enabled, the golden energy ball, the blue industrial ball, the red detection ball, and the white science ball obtained will not affect normal use or the accumulation of permissions. However, if the transaction is given to others, the accumulation will not be included."

"Note: The golden energy ball is the most important and core material for building mechanical creations. Please do not waste it easily."

"Note: White Tech Balls can only be used in mechanical creation."
