Su Wu quickly found an answer: no shadow is produced when the light is perpendicular to the object.
But Su Wu quickly thought that the 'shadow trick' could get out of the shadows produced by various objects, but there was no way he could make the light illuminate all objects vertically!
Suppose that after entering the simulation game, you do not turn on the light, but bring a flashlight into the game and let the flashlight shine vertically on the ground. It may not produce a shadow - it is just a possibility. Does the light outline of the flashlight count as a shadow?
This method has many disadvantages, and no matter how careful you are, it may overturn.
Su Wu thought of the shadowless lamp in the hospital again.
He learned about the principle of the shadowless lamp and found that the shadowless lamp only minimized the umbra and could not completely eliminate the shadow.
Even if shadowless lights work, you can install shadowless lights in the room, but what about outside the room? What about the corridor? What about the corridor?
He doesn't have the financial resources.
Since where there is light, there will inevitably be shadows. Can I choose to walk only in darkness?
An idea suddenly appeared in Su Wu's mind!
He immediately turned on his phone, ignored the messages in the work group, and opened a small group called "Fishing Guys".
Su Wu edited a message: "Dear brothers and sisters, does anyone have an infrared night vision device?
Or does anyone sell this thing? Looking for an infrared night vision device with good performance, it doesn’t matter if it’s second-hand or second-hand, the budget is within 5,000!”
Within five seconds of sending the message, a group member named "Outdoor Fishing Equipment Collection" added Su Wu as a friend.
As we all know, fishing is an outdoor sport.
Night fishing is one of the great pleasures of fishing. Fishing on rivers in the wild will inevitably lead to bumps and bumps. It is normal for some people to sell infrared night vision devices to help others see the road clearly at night.
Various situations are prone to occur outdoors. Su Wu has a friend who once made eye contact with a wild boar by the river.
After adding Su Wu as a friend, the 'Outdoor Fishing Guys Equipment Encyclopedia' sent him several links, all of which were various brands and types of infrared night vision devices sold in his store.
While Su Wu asked him about the specifics of various brands and types of infrared night vision devices, he opened an app for buying and selling second-hand goods.
For such expensive things, you always have to compare them carefully before you know what to expect.
Entering the main interface of the app, many products pushed by big data will appear on the screen.
Because Su Wu likes to browse pet cats, dogs, toys and other products in this app, most of the big data pushed to the main interface are these things.
Usually when he saw these, he would glance at them, but this time he was attracted by a product.
It was a bone flute carved with mysterious patterns, similar to animal leg bones, and one end was wrapped with chiseled copper patterns.
Here is a rough introduction to this product: Gangdong/Gangling, ox bone flute, breaks magic and suppresses evil, calms emotions...
The product introduction words stirred Su Wu's thinking.
He clicked in and browsed several similar products along the feed.
The shadow ghost exists beyond common sense, so can we kill it in a way that goes beyond common sense?
For example, use this similar magic weapon.
It’s a simulation game anyway, why not give it a try?
The phone was buzzing and vibrating, and the "Outdoor Equipment Encyclopedia" picture kept popping up in the upper left corner. Su Wu thought about it and decided that he might give it a try.
And be prepared with both hands.
He entered the infrared night vision device into the app and searched for related products. After browsing around, he had an idea in his mind. He continued to chat with the outdoor equipment encyclopedia to negotiate the price, and finally purchased a second-hand monocular head-mounted infrared device for 5,800 yuan.
Night vision goggles.
Because it was in the same city as Outdoor Equipment Encyclopedia, the other party readily agreed to arrange for a store clerk to deliver it directly to your door within two hours.
Later, Su Wu made another operation on the app and bought a 'gang hole' that was said to be a yak bone for 3,000 yuan.
He repeatedly confirmed with the seller that the hole was made of yak bone.
After all, he browsed similar products and found that there were many that claimed to be made from the calf bones of eminent monks...
The situation now is strange, he is very jealous of things related to people.
Moreover, who knows whether the calf bone was taken from a real eminent monk?
The seller promised to arrange urgent shipment and try to deliver the items to Su Wu this afternoon.
Su Wu breathed a sigh of relief.
Within ten minutes, nearly ten thousand yuan was scattered.
Although his parents passed away and left him two houses and hundreds of thousands in savings, he kept those assets well and never used any of them.
The money he is spending now is his savings from working in the past two years.
Nearly one-eighth of the savings were lost. It would be a lie to say that I don't feel sad.
But when he thought that these things might help him gain a foothold in the future and pave the way for his current self, he felt that the money was well spent.
After that, Su Wu clicked into the tenant group called "Ping'an Garden 7 Buildings" and clicked on the landlord who occupied the entire 7 buildings with a total of eight floors: "Brother, can the voice-activated lights in the corridor be repaired?
I almost broke my knee walking up the stairs this morning."
The landlord doesn't have to work. At home, he only drinks alcohol and beats his wife, and plays music on his mobile phone.
So I quickly replied to Fuwu’s message: “It will be repaired next month.”
"You said the same thing two months ago..." the tenant 'Qingyu' jumped out and said.
"It really needs to be repaired. You can't even see the stairs at night if you don't use your mobile phone." said the tenant 'Peppa the Sheep'.
Afterwards, a few more tenants popped out one after another to say a few words.
When questioned by the tenants, the landlord did not panic at all and just said: "I said it would be repaired next month. If you are anxious, you can pay for it yourself!"
Voice-activated lights don’t cost much!”
Generally, when a landlord becomes aggressive, the tenants will keep quiet unless they no longer want to live here.
These tenants have lived in Ping An Garden for three to five years or even a long time. Just moving requires a lot of energy. Having no way out due to fighting with the landlord is not the best choice for these tenants who have families and families to live with.
The group became deserted.
But not long after, a message popped up in the chat box: "I'll fix it, I'll pay for it!"
The person who sent the message was Su Wu.
The landlord was eager to save a few dollars, so when he saw this, he replied as fast as he could not retract the message: "Okay, okay, you can fix it, you can fix it, when will you fix it?"
I’ll give you the key to the main switch of Building 6.”
Not long after the news was released, a person named "Hardware Tools" said: "I have various types of voice-activated lights here. You can buy them from me, and I can also help install them."
"I'll fix it today. I'll buy it from you, and you'll help us install @HardwareTools." Su Wu didn't want to cause any trouble, so he directly called the person in the group.
This settled the matter.
He chose a voice-activated light with "intelligent voice control/remote control" functions from the "Hardware Tools" and installed it in each corridor.
Even the voice-activated lights that were still working were replaced.
At the same time, I quietly went to get the key to the main switch box.
