"Since there are only two underground soundproof rooms, I can only keep the third one in the open air in the backyard, surrounded only by iron cages," He Hehe continued, "Now that a month and a half has passed, it still maintains the activity pattern of daytime activity and nighttime dormancy, and there is no attenuation of vital signs." “

"Could it be just individual differences?" Gou asked, the same human beings, different people can hold on for different amounts of time when there is no food intake. Even if they are zombies, it is normal for there to be some differences between different zombie individuals.

"So far, it is true that this possibility cannot be completely ruled out, but according to follow-up tests, this possibility is unlikely." He Hehe paused and said, "I tried to move the zombie that had been dormant in the basement for a long time to the ground and locked it in the open air for a few days, and the result was that in the open air, it regained its activity pattern during the day and dormant at night. ”

"So I'm guessing that zombies can somehow get a source of energy from the outside world in the open air." When he said this, He He smiled a little uncomfortably, and then looked at Gou Ke again, as if he was worried that Gou Ke would laugh at him.

"Do you photosynthesize like plants?" Gou Cao wanted to laugh and forcibly put the smile back, Gou Cao had seen too many bizarre things for most of the year, and it was not impossible for zombies to become vegetative people in comparison. "But zombies aren't green." After speaking, he glanced around, and most of the people present except for He Hehe, Hao Aiguo and Bai Yutian had smiling expressions.

"First of all, it's not necessarily plants that can photosynthesize, animals like sea slugs and spotted newts can also do photosynthesis." Seeing this, He Hehe's tone became a little anxious. "Secondly, it doesn't have to be green to be able to photosynthesize, in fact, there are pigments that can absorb light energy, and then there are organs in the body that can convert light energy into chemical energy for storage."

"After the zombie, the blood will turn black and the body color will also deepen, which makes the zombie can absorb a wider range of sunlight than greenery." As if realizing that he was a little rude, He Hehe said again in a more soothing and steady tone, "In this way, the zombies absorb more energy from the light than the green plants, which is enough to support them to carry out high-intensity actions in a short period of time. ”

"In this way, it makes sense, the efficiency of photosynthesis to absorb energy is not as high as the efficiency of direct feeding, so it is slow to act in normal times, which can save energy." Gou Cao accepted this statement, so he continued, "But zombies have a higher photosynthesis intensity than green plants, so they can also run and chase prey in a short time, right?" ”

"That's right, but I don't know much about the more specific mechanism of action, and the conditions here are really limited, so I can't carry out more detailed research and analysis." He Hehe was happy when he saw that someone agreed with his words, but then he became a little regretful.

"Such a scheming child, falling into the hands of Bai Yutian is really wronged by you." Gou, who had always been curious, naturally became happy after the initial answers to the questions that had plagued him for many days. So I couldn't help but complain in my heart about some of the things that I didn't, who would gossip so much if I was in a bad mood.

After He Hehe finished speaking, the people at the table exchanged some miscellaneous things. In the meantime, Gou Ke made a request to join them, which was granted.

In addition, because Bai Yu sweetly told about Gou Cao's strength against the corpse chaser, coupled with Hao Aiguo's acquiescence, the others agreed to Gou Cao's additional additional conditions.

The first is that the rover and the ancillary items on the rover are still owned by Gou Cao's private individuals, rather than being confiscated and distributed uniformly like the resources brought by others;

the second is to build a separate small garage for Gou Cao in the backyard of the villa and prohibit others from entering;

Third, Gou Cao can keep a part of the resources obtained independently by going out to collect, and Gou Cao can exchange personal belongings for non-scarce items in public goods;

Fourth, both Gou Cao and the Rover can go out with the team, but when the Rover needs to be dispatched, it must be piloted by Gou Ke himself, and no one can board the Rover without Gou Ke.

On the other hand, Gou Cao also provided enough benefits to make them excited: five Type 30 police 9mm pistols, 300 rounds of P08 9mm pistol rounds, and three boxes of Type 47 military compressed biscuits in batches over the next five days.

The Three-Zero pistol and suppressor were seized from the iron-masked man who chased the corpse, and they were scanned with a printer and ready for mass production. The P08 9mm pistol cartridge is also the standard ammunition of the JS9 submachine gun, and the suppressor is commonly known as the silencer, but in fact it does not completely eliminate the sound. The built-in suppressor of the Type 30 pistol can reduce the sound of the Type 30 pistol firing to 15 decibels, and the flame suppression effect is also very obvious.

Five pistols fill the gaps in the Villa's thermal arsenal, suppressors allow them to prevent zombies from being drawn to a wide range of gunfire when attacking zombies, and compressed biscuits greatly reduce the logistical pressure when going out to collect from long distances. Therefore, Gou Cao was welcomed by many people in the settlement.

Gou Cao had just joined this group of survivors, and he couldn't provide them with too much firepower, so it was not too late to make up a few JS9 submachine guns to provide them with a few JS9 submachine guns to strengthen their firepower after establishing enough trust. Gou Cao needs to stay here for a few days, and if something happens to them, it won't do him any good.

After everything that should be said, everyone dispersed, and Hao Aiguo proposed to give Gou Cao a single room to live in, but Gou Cao refused. He thought it would be good for him to sleep in the rover's cabin, and the last time he was attacked by the corpse chasers gave him a lot of shadows, so he was reluctant to leave the rover at night.

After that, He Hehe took Gou Cao to the backyard to choose a site, and Gou Cao chose to build a small board house along the fence in the northwest corner of the villa as his garage, rover renovation workshop and a basement to sleep at night. There is not enough light here, so there are no medium potatoes, and building according to the fence can save two walls and save a lot of boards.

The construction of the prefabricated house is very smooth, because Gou Ke does not plan to live here for a long time, so it does not need to be built very firmly, only need to erect a 50mm diameter steel pipe as a support, with several plates spliced in the middle, and the top is covered with canvas. So with the help of a few survivors, it was built before nightfall.

The plate is produced by a printer with two sheets of iron and then filled with plastic foam, because the structure is simple and does not need to change the atomic bond structure, so the production speed is very fast. Gou Cao sat down and took it out of the rover after the printer was ready. Canvas and steel pipes were provided for the villa settlement.

When everyone went back to sleep and Gou Cao returned to the Rover, Cortana suddenly reminded him, "Gou Cao, there are new drawings back." ”
