"Boom" came to the basement four floors, and the heavy iron door in front of him suddenly opened, and the bottom was a man-made space for planting underground crops, greenhouse crops, and breeding edible insects and giant rats.

When the gate opens, two high-powered searchlights guide the way. Not far in front of me, there were a few bright lights, and a few busy figures came into view.

"Isango, this is the breeding area." Jeff stayed by Ethan's side, acting as his guide.

"Hey Jerry, how's it going today?" Walking to the lights, Christina shouted to the laborers.

Christina's voice came from behind the hood of the hazmat suit, and a young man in the crowd turned around happily and replied, "Eh! Christina, why are you here? ”

"Yi ...... Lord Ethan. Recognizing the identity of the visitor, Jerry bowed respectfully to Ethan.

Ethan didn't know what to do, so he smiled and bowed his head.

"Today it's still the same, it's calm, but every now and then one or two rats will come out to scare people." The rats in Jerry's mouth are not giant rats, just small rodents, but although they are small, they are the length of an adult's forearm, and they usually weigh 10kg-20kg.

As the two chatted, Ethan surveyed his surroundings, the dark holes, the rudimentary sheds of plastic roofs and rusty iron pillars connected together, and the sound of "clicking" and some strange wriggling sound came and went. At the same time, Ethan also noticed several workers in front of him, who were picking up iron hoes to loosen the soil, digging in the ground, or standing in front of foam boxes to put fodder, who were not wearing radiation protective suits like those of the Fifth Operations Group. Although they go through a radiation-canceling pool before every commute, their skin is still covered in red sores due to long-term exposure to radiation.

"Jerry, can you show us around the breeding area?" When the chit-chat was over, Christina asked.

"Of course, please come with me." Jerry put down his hoe and led the group to the outermost shed.

"This is for insects, these are the larvae of the Migs," Jerry said, gesturing to the yellowed foam box in front of him.

Everyone looked for prestige, only to see white maggots wriggling on the food scraps.

"There's an adult Mig over there."

Jerry continued to walk inside, and the two rows of containers for feeding were constantly being upgraded, and by the time they reached the back, they had become large metal containers.

The MiG worm has a thick brown-black carapace, and its six slender arthropods make a sizzling sound in the iron box. They are slow and docile, and it only takes 7 or 8 months for them to grow from larvae to adulthood when they are well fed. The adult MiG worm is 0.5m-0.8m long, weighs 20-35kg, has a high meat growth rate, and the meat of the Mig worm is non-toxic and harmless, and long-term consumption will not have a bad effect on the human body, so this insect is the first choice for most shelters to raise.

"At present, there are more than 500 MiG worms raised here, and of course, this includes the larvae, and if you count the Mige worms, there are only 32 of them."

For the time being, this shed is only home to the Mig worm.

Out of the shed, Jerry led the group to the reptiles.

"These are earthworms, which are very well fed and grow very quickly. The longest earthworm we've ever raised is 12m long. Jerry gestured with his hands outstretched.

"Good guy, 12m long!" Everyone looked shocked.

Jeff, who was looking down to take notes, also widened his eyes and muttered in a low voice, "12m, how many people can you feed......"

Ethan was also surprised, no wonder the place was almost twice the size of the other sheds, and the containers were larger and stronger.

In addition to earthworms, there is also another dioecious creature in this shed, that is, the xenomorph snail.

Walking to the two closed huge glass tanks, Jerry scratched his head and said with some annoyance: "These big snails are very annoying, they eat almost everything, and they used cement boxes and iron boxes to raise them, but they have all gnawed them." ”

Jerry pulled the black cloth that was used to shield him from the light, and two huge snail shells, a man tall, burst into everyone's sight.

Feeling the stimulation of the light, the snail probed its tentacles out of its shell, and suddenly became larger several times, making the originally somewhat spacious glass tank seem cramped.

Jerry picked up the food from the feed box and fed it, explaining, "These two big snails are 1 year old, and it's almost time to be slaughtered. Speaking of which, it's quite reluctant, but I've watched them grow up. ”

"Good...... It's so meaty. They didn't feel Jerry's sadness, and everyone just hoped that after slaughtering the two big snails, the dragon beard steak could be reduced in price and let them taste what it was like.

Like Mig worms and earthworms, mutant snails grow extremely fast, and it only takes one year to grow from a fingernail size to a mature body weighing 200kg, and snails are allogeneic breeding, and only two snails are needed to reproduce. A litter can produce 400-800 snail eggs, which can reproduce again after 6 months.

It's just that this mutated snail eats a huge amount of food and has high requirements for the breeding environment. Juvenile snails are weaker and must live in mud or concrete, and the air should not be too dry, so they need to be sprinkled with water regularly.

The advantage of breeding large snails is obvious, that is, the meat yield is high. The soft snail is almost completely edible, and the shell is as hard as baked ceramic, and can be used in the development of some weapons. However, the shortcomings are also obvious, their breeding conditions are harsh, and they need to consume a lot of manpower and material resources, and the resource-poor No. 125 Vault is temporarily unable to support it. Therefore, in a short time, the shelter will no longer plan to breed large snails.

Covered in a black cloth, Jerry led the group to the next area.

"Whew!" Seeing someone coming in, the giant rat stopped gnawing on the iron cage and bared his teeth at Ethan and the others.

"Ethan Isango, what's wrong with you?" Jeff noticed Ethan's strange appearance and asked.

The scene in front of me has changed, like an extra layer of faint filter, there is an extra blood bar on the head of the giant rat in the cage, and the crimson red letters appear on the blood bar:

【Giant Rat】Lv.1

Ethan looked intently and noticed that the giant rat in the cage had become more manic.

"Is this a battle-ready state?" Jeff asked, guessingly.

When the system fighters become aware of the presence of hostility, they go into combat on their own.

"Hahaha, Isango was scared." Realizing what was happening, Christina burst out laughing.

Ethan came back to her senses and looked at Christina suspiciously. The abnormality in front of him subsided, and the blood bar on the giant rat's head disappeared with it.

"Isango, that's right, once you realize the existence of a threat, you will enter a combat state, and if you are attacked, you will also enter a combat state." Jeff also explained to Ethan with a smile.

Ethan pouted and looked away.

"It's not surprising that I was scared when I first saw a giant rat." Jerry smiled and said.

"It's not easy to raise these big rats, they are ferocious, they can't be raised, and if you are not careful, there will be hurting incidents. But," Jerry swallowed halfway through his sentence before he added, "These giant rat meat is superb, and you won't forget its delicacy once you taste it." ”

Christina and the others nodded slightly, even if they hadn't tasted it themselves, they had all heard of the name of giant rat meat, and some giant rat meat lovers even compared them to beef.

"Come, I'll show you the crops we grow ourselves." Jerry beckoned, and with some excitement led everyone to a large shed at the end.

Mutated wheat with very small kernels due to radiation, fern roots that can be planted outside the greenhouse but with a poisonous skin, rice that can be mutated on dry ground, and a few other crops that are grown in small quantities in the greenhouse, are all the crops currently grown in the shelter.

After thanking Jerry, the 5th Operations Team returned to the Vault.
