Sanssouci Island, Western-style building.

Ye Xiao and Long Jingyun didn't stay long in the Neon Country after getting the photos hidden by the fairy island husband, and returned to Sanssouci Island directly.

"These are the 'collections' of Senjima."

Ye Xiao put a few document bags on the long table in the restaurant and said, "Whether you can find Xiandaofu, whether you can find the 'Black Fire' test base, it depends on these photos, you can take a look at these photos first." ”

Although he had a psychological preset about these photos of Xiandaofu before opening the portfolio, when he really saw these photos in the portfolio, everyone, including Li Ang, was shocked.

These photos can no longer be described with the sentence "not suitable for children", that is, Song Xiu, He Ziming, and Tang Feng are all shocking.

As for Long Jingyun, after finding these photos, she didn't look at them at all.

Although she didn't know the women in the photos at all, out of respect for these women, Long Jingyun didn't look at these photos.

Together, there are hundreds of photographs in these portfolios, some taken at the test site and some taken outside the test site.

In addition to having a general understanding of the situation in the test base, the photos in the test base do not have much reference value, so after several people eliminated all the photos in the test base, only the photos taken outside the test base were left.

He Ziming moved his somewhat stiff neck, looked at the photos spread on the long table in the restaurant, and said, "Just judging from these photos, I can't find any useful clues." ”

"Stinging dragon, let's look at it tomorrow, after looking at the photos for a day, I see this face of Xiandao now, I want to vomit." Tang Feng is also complaining.

"Whew!"

Ye Xiao took a deep breath, then jumped down from the table, clapped his hands, and said to a few people in the restaurant, "You guys go to rest first, and continue tomorrow." ”

Song Xiu, He Ziming, Li Ang, Tang Feng, and Blackbird at the table moved their bodies and left the restaurant.

After Ye Xiao moved his waist and neck for a while, he sat down at the dining table again and continued to stare at the photos on the dining table.

At this time, Ye Xiao was completely competitive with the dozens of photos on the table, and he had a posture of not studying a reason and vowing not to give up.

"Still researching?"

Long Jingyun put a bowl of mustard and shredded pork noodles on the table and said, "You haven't eaten for a day, let's eat something first." ”

"It smells so good."

Ye Xiao sniffed his nose, and his attention was attracted by the bowl of mustard and shredded pork noodles that Long Jingyun put on the table.

There were a few green shallots floating in the clear noodle soup, and the noodles of uniform thickness were stewed shredded meat and mustard, and in addition to shredded meat and mustard, Ye Xiao also unexpectedly found a few slices of shiitake mushrooms.

"Where did these shiitake mushrooms come from?"

Ye Xiao picked up a piece of shiitake mushrooms with chopsticks and asked Long Jingyun.

"We pick it well in our own greenhouse."

Long Jingyun sat down on the chair next to her, supported her chin with one hand, completed two beautiful crescents with her eyes, and said: "I went to the greenhouse today to see, not only shiitake mushrooms, but also cherry tomatoes, eggplants, strawberries, and greens are growing well." ”

The last thing that is lacking on Sanssouci Island is seafood, and the most important thing is fresh vegetables.

At the beginning, Ye Xiao thought of imitating the method of "Hydra" in the past and replenishing it through airdrops.

This is indeed a solution, but it is also a palliative solution.

In particular, Ye Xiao plans to use the optical camouflage background plate to completely cover Sanssouci Island in the future, so that Sanssouci Island will "disappear without a trace", and then he will no longer be able to rely on airdrops for replenishment.

Moreover, the supply of fresh vegetables is not as good as rice, flour, oil and grain, if you completely rely on the supply from the outside world, the frequency of supply will be very high, and correspondingly, the cost will also increase.

After discussing with others, Ye Xiao decided to reclaim farmland and build a greenhouse on Sanssouci Island to be self-sufficient.

From the perspective of natural factors, the soil and climate of Sanssouci Island are not suitable for farming, but if you use soilless cultivation, you do not need to consider the influence of soil quality and temperature.

After the first greenhouse test and success, more than a dozen digital greenhouse for soilless cultivation have been set up on Sanssouci Island, and the vegetables and fruits in them are fully enough for the consumption of the entire Sanssouci Island.

Ye Xiao even plans to enclose a piece of land on Sanssouci Island for animal husbandry, and match the resources of this "paradise".

When all his attention was on those photos just now, Ye Xiao didn't feel hungry, but now that he was seduced by the fragrance of Long Jingyun's bowl of noodles, Ye Xiao suddenly felt hungry.

You're welcome, pick up the noodle bowl and gobble it up.

While Ye Xiao was feasting, Long Jingyun looked at the photos on the table.

Although she was very reluctant to these photos in her heart, in order to help Ye Xiao find clues about the "Black Fire" test base from these photos as soon as possible, Long Jingyun endured the rejection and disgust of these photos and studied them carefully.

A large bowl of noodles, in less than five minutes, was wiped out by Ye Xiao even with soup and noodles, wiped his mouth with a tissue, and redevoted himself to the study of these photos.

"You see, the two photos were taken on the same day, but the light and darkness are different."

Long Jingyun picked out two photos from these dozens of photos, handed them to Ye Xiao and said, "This one is obviously darker than the other." ”

"Although these two photos were taken on the same day, they were taken at different times and from different lighting angles......

Before Ye Xiao could speak, his eyes lit up, he stood up from the dining table and said, "I thought of it!" ”

"I missed a key point! Light time! ”

Ye Xiao put the two photos that Long Jingyun handed him side by side, and said: "Different places, the sunshine intensity, time, and angle are different, for example, in our country, the sunshine time is different in the south and the north, and the sunshine intensity is also different......

Ye Xiao seemed very excited, and his mouth kept talking, just like the sense of accomplishment he got after solving a math problem that had been stuck for a long time when he was studying.

In the lower right corner of these photos, there is the year, month, day and time when the photos were taken.

Combined with the time of shooting on the photo, as well as the angle and intensity of sunlight in the photo, it is possible to make an inference.

"Father-in-law Sun, I love you!"

Ye Xiao opened his hands and shouted.
