(It's a new week!) Last week's best result was ranked 25th, and this week I continue to ask for favorites and clicks! Thank you! ）

Airplanes......

With Ye Bing's order, the shell of the entire base was restless again, and then, I saw that the silver liquid metal on the surface of the shell seemed to have turned into a liquid state again, and all of it slid to the bottom, leaving only a thin and transparent protective film on the case!

Ye Bing nervously pulled out a chair from behind him, put it on the side closest to the zombie attack, and sat on it himself, watching the debut of the Beam Tower with a sense of anticipation!

As mentioned before, although the way the primary zombie moves is very strange, it can also run as fast as an adult man walking briskly. Therefore, within a ten-meter radius of the protective circle, the zombies came to the front of the base in just a few charges!

Watching the dozen or so zombies attack the main base step by step, Ye Bing's heart once again beat rapidly!

Finally, just as the distance between the zombies and the main base was reduced to five meters, the Beam Tower made its counterattack!

I saw a pure color light start from the bottom of its several prisms, slowly light up, until the bright light excited the entire prism, a dazzling white light suddenly shot out, and hit the head of one of the zombies accurately!

Rumble!

Accompanied by the laser launch, there was an explosion, and the zombie that was hit collapsed directly to the ground, and the entire upper body was blown to pieces, and it looked like it was dead and couldn't die anymore!

"Wow, that's strong!"

Ye Bing jumped up from the chair and said loudly. This level of power is comparable to a heavy weapon of human beings, to say the least! Moreover, the beam tower also has huge advantages that human heavy weapons do not have, such as not having to consume ammo, for example, with subsequent upgrades, its power will be greatly increased!

However, looking at this scene, Ye Bing suddenly had a little more worry. He hurriedly asked, "Natasha, the power of the beam tower laser is so strong, will it blow up the magic crystal in the zombie's brain?" ”

If that's the case, that's bad!

"No, it won't. The Crystal Crystal's outer shell is highly resistant to heat and explosion, and lasers will not destroy it, as long as damage from a blunt object is a threat. Natasha said.

After listening to Natasha's explanation, Ye Bing was finally relieved. Fortunately, as long as you don't blow up the magic crystal, you can do anything. Even if the magic crystals are blown away by the shockwave, as long as you have the silver key that can detect the existence of the magic crystals, you can easily collect them all!

On the other side, the battle between the zombies and the beam tower continues.

After the first zombie was shot down mercilessly, the remaining zombies still charged towards the main base without fear of death!

As the beam tower was recharged again, a second killed zombie appeared, followed by a third.

However, at the same time that the third zombie fell to the ground, the remaining eight zombies had already rushed to the base!

"Strange, what is this beam tower doing, why is the launch so slow! Hurry up! ”

Seeing that the rancid faces of the group of zombies had been attached to the protective film and kept gnawing, while the beam tower still maintained an unhurried shooting speed, Ye Bing's heart was almost broken!

At this time, Natasha's voice echoed from inside the base: "Commander, our base is under attack, and the external defense system is expected to be able to hold out for three minutes and eleven seconds before the base is destroyed. Threat level, low. ”

At the same time, the large screen in the main base immediately switched to the status interface of the Doom base. Judging from the image, the parts that have not been attacked by zombies are green, the parts that have been gnawed and scratched by zombies are yellow, and the areas that have been attacked are dark yellow with a red trend!

Next to the main base image is the dynamic health bar. It seems that although the attack of the zombies seems to be fierce, after all, the number is small, and the damage caused to the base is not exaggerated as imagined.

Sure enough, exactly as Natasha expected. A minute later, as the last zombie was also knocked down by the laser from the beam tower, the first encounter between the base and the zombies ended in a complete victory for the base!

After making sure that all the zombies were dead and could no longer die, Ye Bing walked out of the base with the silver key.

"Sure enough, it seems that ordinary primary zombies will definitely not burst out of magic crystals."

Ye Bing shook his head and sighed. He had been exploring the group of dead zombies for a long time with the silver key, but he didn't even react at all.

But fortunately, there is only one thing to be thankful for, that is, even if it is just the corpse of an ordinary primary zombie that cannot produce magic crystals, it can still come in handy after building a material recovery tower.

Ye Bing counted slightly, and there were a total of eleven corpses of primary zombies lying on the ground. According to Natasha, these eleven zombies can recover about 0.5 units of energy, which is quite gratifying. After all, this is just the harvest of an operation, as long as Ye Bing can attract more than four waves of zombies in one day, then the energy rate obtained through the material recovery tower will reach twice that of the solar crystal panels!

In this way, Ye Bing's daily "salary" in the future will be able to reach three units of energy, so as long as he accumulates about four days, he will be able to build a more powerful building such as the "Mechanical Barracks" as he wishes!

In this way, Ye Bing once again walked outside the protection circle without hesitation with the little brightness and expectation for the future in his heart!

In a blink of an eye, the time had come to the third day after Ye Bing entered the base.

In the quiet base, there are only sweeping robots and Ye Bing working.

He was still wearing the silver tights. Not only because of the comfort, but also because the tights give him a strong sense of security.

If you look closely, you can see that there are already four or five holes in the extremely strong bodysuit! Although each hole may seem so frivolous, only those who have experienced it know what a horrible thing would have happened without the protection of this layer of clothing!

In the past two days, in order to collect more zombie corpses, Ye Bing has done more than a dozen times to act as a human bait to attract zombies. Most of the time, he can retreat into the base unharmed, waiting for the Beam Tower to take out the zombies one by one.

However, there are always exceptions. There were two of them, so that Ye Bing almost put his own life in it.

The first crisis happened on the night he began to attract zombies.

After the first success in attracting zombies, Ye Bing followed up with a second success. However, the number of zombies harvested that time was not large, only five, which was a drop in the bucket compared to the huge demand for building facilities.

Therefore, in the third operation, Ye Bing decided to do a big one.
