3. Gangdong
Su Wu quickly found an answer: no shadow is produced when the light and the object are perpendicular to each other.
But Su Wu quickly thought that the ‘shadow ghost’ could come out of the shadows produced by various objects, and he had no way to make the light shine perpendicularly on all objects!
Suppose after entering the simulation game, he did not turn on the light, but brought a flashlight in, and shone the flashlight perpendicularly on the ground, maybe no shadow would be produced - but it was just maybe, does the outline of the flashlight count as a shadow?
This method has many disadvantages, and no matter how careful you are, you may fail.
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 reduced the shadow to the weakest, and could not completely eliminate the shadow.
Even if the shadowless lamp works, he can install a shadowless lamp in the room, but what about outside the room? What about the corridor? What about the staircase?
He did not have the financial resources.
Since shadows are inevitable in places with light, can he choose to walk only in the dark?
Su Wu suddenly had an idea!
He immediately turned on his phone, ignored the messages in the work group, and opened a small group called "Fishing Man".
Su Wu edited a message: "Dear brothers and sisters, does anyone sell infrared night vision goggles?
Or does anyone sell this thing? I want a good infrared night vision goggles, first-hand or second-hand, the budget is less than 5,000!"
Less than five seconds after sending the message, a group member named "Outdoor Fishing Man Equipment" added Su Wu as a friend.
As we all know, fishing is an outdoor sport.
Night fishing is a great pleasure of fishing. Fishing by the river in the wild is bound to bump and bump. It is normal for someone to sell infrared night vision goggles to help others see the road clearly at night.
Various situations can easily happen outdoors. Su Wu has a friend who once met a wild boar by the river.
After "Outdoor Fishing Man Equipment" added Su Wu as a friend, it threw him a few links, all of which were infrared night vision goggles of various brands and types sold in its store.
While Su Wu was asking him about the specifics of various brands and types of infrared night vision goggles, he opened an APP for buying and selling second-hand goods.
For such expensive items, you have to compare them to get a rough idea.
Entering the main interface of the APP, many products pushed by big data appeared on the screen.
Because Su Wu likes to browse some pet cats and dogs, cultural relics and other products in this APP, most of the big data pushed to the main interface are these things.
Usually he just glanced at them when he saw them, but this time he was attracted by a product.
It was a bone flute with mysterious patterns carved on it, similar to animal leg bones and one end wrapped in copper patterns.
Below is a rough introduction to this product: Gangdong/Gangling, ox bone flute, breaking the law to suppress evil, calming emotions...
The words in the introduction of the product stimulated Su Wu's thinking.
He clicked in, and then browsed several similar products along the push.
Shadow Ghost is an existence beyond common sense, so can it be killed in an unreasonable way?
For example, using a similar magic weapon.
Anyway, it is a simulation game, why not give it a try?
The phone was buzzing, and the avatar of "Outdoor Equipment" kept popping up in the upper left corner. Su Wu thought about it and thought he could give it a try.
And he had to be prepared for both situations.
He entered the infrared night vision device in the APP, searched for related products, and after browsing around, he had a plan in mind. He continued to chat with Outdoor Equipment and negotiated the price, and finally bought a second-hand single-tube head-mounted infrared night vision device for 5,800 yuan.
Because he was in the same city as Outdoor Equipment, the other party readily agreed to arrange a clerk to deliver the goods to the door in two hours.
Afterwards, Su Wu operated in the APP again and bought a "Gangdong" that was said to be made of yak bones for 3,000 yuan.
He repeatedly confirmed with the seller that this Gangdong was made of yak bones.
After all, he browsed similar products and found that there were many that claimed to be made of the calf bones of eminent monks...
The situation was weird now, and he was very afraid of such things that were related to people.
Moreover, who knew whether the calf bones were taken from real eminent monks?
The seller agreed to arrange expedited delivery and try to deliver the items to Su Wu this afternoon.
Su Wu breathed a sigh of relief.
In just over ten minutes, nearly 10,000 yuan was spent.
Although his parents left him two houses and hundreds of thousands of savings after their death, he kept those assets well and never used a penny.
The money he spent now was his savings from working for the past two years.
Nearly one-eighth of his savings was gone, and it would be a lie to say that he didn't feel bad.
However, thinking 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 worth spending.
Afterwards, Su Wu clicked into the group called "Tenants Group of Building 7 of Ping'an Garden" and tagged the landlord who owned the entire 7th building with a total of eight floors: "Brother, can the voice-controlled 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, apart from drinking and beating his wife, he plays with his phone and browses certain audio.
So he quickly replied to Su Wu's message: "It will be fixed next month."
"You said the same thing two months ago..." Tenant 'Qingyu' jumped out and said.
"It's time to fix it. You can't see the stairs at night without your phone." Tenant 'Peppa the Sheep' said.
Then several other tenants jumped out and said a few more words.
The landlord was not panicked at all when questioned by the tenants. He just said: "I said it will be repaired next month, so if you are in a hurry, you can pay for it yourself!
The voice-controlled light doesn't cost much!"
Generally, when the landlord is being arrogant, the tenants will keep silent, unless the tenants don't want to live here anymore.
These tenants have lived in Ping'an Garden for three to five years or even a long time. Just moving will take a lot of energy. Fighting with the landlord and leaving themselves with no way out is not the best choice for these tenants with families.
The group became quiet.
But not long after, a message popped up in the chat box: "I will repair it, I will pay for it!"
The person who sent the message was Su Wu.
The landlord was eager to save a few dollars, and replied as fast as he could not withdraw the message: "Okay, okay, you fix it, when will you fix it?
I will give you the main switch key of Building 6."
Soon after the message was sent, a person named "Hardware Tools" said: "I have various types of voice-controlled lights here, you can buy them from me, and I can also help install them."
"We will fix it today, buy them from you, and you can help us install them @Hardware Tools" Su Wu did not want to make any more trouble, so he directly tagged the person in the group.
So the matter was finalized.
He chose voice-controlled lights with two functions of "intelligent voice control/remote control" from "Hardware Tools" and installed them in all corridors.
Including those voice-controlled lights that can still be used.
At the same time, he quietly went to get the key for the main switch box.
