In the cave where the No. 1 sub-base is located, the entrance of the cave has long been blocked by boulders transported by mineral engineering vehicles, which makes Zhang Feng feel a lot safer.

The cave and its surroundings are full of swift mechanical insects, cleaning up all kinds of original creatures, not to mention snakes, and even an ant will be sucked away by mechanical insects as bioenergy and put into the energy conversion furnace.

Sub-Base 1 projected several soft rays of light, illuminating the cave that was supposed to be pitch black.

Zhang Feng set up an iron pot (naturally specially made for the sub-base), used dead branches as fuel, simmered slowly, and after a while, a pot of roe deer meat was steaming.

"Wow, it's so fragrant!" Zhang Feng sniffed vigorously. Seeing that the heat was about the same, I picked up some mushrooms next to it and put them in.

These mushrooms are naturally selected after countless experiments, so that many small beasts are fine after eating them, and they are not poisonous before they are selected.

"Mushroom stew, it's really delicious!"

Zhang Feng served a bowl and almost swallowed his tongue when he ate it.

After a few bowls of belly, patting his bulging belly, Zhang Feng hiccuped and lay down in the living cabin of the sub-base with satisfaction.

In addition to being lonely, he feels that he is doing really well now. At the very least, he had eaten more delicacies these days than he had eaten in the previous twenty years combined.

Probably because of the abundant aura here, the animals raised are extremely beautiful. For example, the little beast with sharp horns that he just ate resembled a roe deer, the flesh was smooth and tender, and it was definitely not comparable to the roe deer on the earth. Then reconcile the natural rock salt found in a cave by mechanical prospecting ants...... Tsk, it tastes great!

"Hey, it would be great if I could live like this on Earth!" Zhang Feng sighed and fell asleep groggily.

Now the otaku is to sleep and taste all kinds of delicacies of the world.

............

"Drip—"

With a crisp sound, a meteorite-like thing glowed with a burst of red light, suspended on the ground, and after a burst of "clucking ......", it transformed into a metal building more than ten meters high with science fiction colors.

"Sub-base 2 is activated, with 0 energy reserves, 0 common metal reserves, 0 synthetic metal reserves, and a production capacity of 150 basic combat units per day. ”

"It has a certain ability to defend against ground and air. ”

"There is a wormhole between the main base and each sub-base, and the interior can be freely interconnected. ”

"Resources can be freely distributed between the main base and the sub-base, as well as between the sub-base and the sub-base, and can be transferred directly through the space connection points. ”

After a day's advance, the mushroom grove has been developed over a distance of ten kilometers. Zhang Feng's second sub-base was built in a mushroom forest.

He felt that the safety factor would be much greater if the sub-bases were set up in different environments.

In this way, the main base continues to produce sub-bases, and the two sub-bases produce velocidal and mechanical insects in a 1:1 ratio.

Production reached the level of 300 units per day, and 1 sub-base.

During these days of exploration, nearly 300 rapids and more than 200 mechanical insects were killed, and more than 60 primary energy sources were also obtained.

The mechanical wreckage was devoured by the second-level swift mechanical bug - anyway, it took about the same time to manufacture and repair, and it was naturally more cost-effective for the wreckage to be devoured and evolved.

Through Devouring Evolution, Zhang Feng obtained a total of more than 50 Level 3 Swift Mechanical Worms.

Compared to the second-level rapids, these guys are bigger, faster, and have much sharper pincers and claws.

Just when Zhang Feng was secretly proud in his heart, he suddenly got a hint from the main base, and the mushroom forest direction lost more than 60 swift mechanical insects at one time.

Zhang Feng's heart sank, and he quickly switched the picture there.

With the link to the main base, Zhang Feng, as the inheritor, can switch his vision to any combat unit at any time.

He could even switch to the mechanical prospector ant if he wanted to. However, mechanical prospecting ants are small and have a narrow field of vision, so there is little point in doing so.

The picture changed, and I saw a giant centipede standing up with the front half of its body, showing its white teeth, "磔磔磔磔-" A sharp cry, with hundreds of legs on both sides of its body, its belly was white, its back was pitch black, but the legs and sides of its body were red.

Nearby, there are more than thirty giant centipedes like this one.

Now, these big guys are still showing off their might, their bodies pounced down, their legs on both sides like countless sharp blades, and the swift mechanical insects everywhere they went were cut in half.

In the blink of an eye, more than 20 were wiped out.

Zhang Feng glared: "Damn! Why did you provoke the centipede nest! Moreover, these guys are too tough!"

In total, nearly 90 were lost, which is nothing for the total number of hundreds of birds around. The crux of the matter is that the swift robot worms have no way to deal with the giant centipedes, and they rely on speed and sharp teeth and pincers, and most importantly, the sea of worm tactics.

However, the swift mechanical bug is fast, but the giant centipede is even faster. Moreover, its hundreds of legs are all blade-like existences, which can defend all directions of its body, and with more than thirty giant centipedes attacking and defending each other, it is not afraid of insect sea tactics at all.

What's even worse is that the black shell on Wugong's back is very hard, and the claws of the swift mechanical insect can't break through its defenses at all.

So far, only two giant centipedes have fallen into the encirclement of the swift mechanical insects due to mistakes, and have been dismembered from their abdomen by a surging of mechanical insects, and the other ones have not been lost.

The battle continues, and nearly a hundred swift mechanical bugs are destroyed every minute.

Spike!

It's an absolute spike!

It's a pity that it was killed in seconds!

You must know that after the establishment of the sub-base, Zhang Feng's current production capacity is only 300 units per day, and it will take a day to make up for the loss of time.

Zhang Feng felt that his heart was dripping blood.

"Why are these guys so perverted, they are simply invincible! And they are not afraid of group fights, and there is no heavenly reason!" When 5 third-level rapid mechanical insects were casually killed by the giant centipede, Zhang Feng finally collapsed.

He didn't expect that the insect swarm he was proud of would be so vulnerable in front of the big centipede.

"Base Fort!" Zhang Feng suddenly had a flash of inspiration in his heart.

"Can the base battery handle these big guys?"

"If you go back to the master, the enemy's combat power is about level four, and as long as it hits, the small cannon of the base can destroy it. However, please note that the current base is not protected by an energy shield, and I am afraid that it will be difficult to resist their attack. The mechanical voice replied.

"Damn! In other words, the base batteries can kill them, and they can also kill the base?
