He has developed a lot of things for Tu Yufan, and the authorities have long noticed him and sent people to secretly protect Tu Yufan. This time Tu Yufan was almost hit, and they secretly investigated the driver and found that a large amount of money had been transferred to his daughter's account some time ago. Later, they found that someone secretly contacted him to deal with Tu Yufan.
"Is that so? Even foreign countries have noticed me."
This country prohibits the use of hot weapons, and Tu Yufan can sense and avoid other dangers in advance, so he is not worried. He just didn't expect that he is just a businessman and can be noticed by foreign countries.
"Yes, Mr. Long, you should rest at home for a while while we investigate the city carefully."
"Well."
Tu Yufan nodded, then turned around and traded blueprints of bulletproof clothing for the future world in the group.
"Brother Fan, this thing is from the military..."
"I know you can only get the civilian version, right?"
"Even if there are advanced ones, your world cannot produce them at the moment."
Xiao Wang's face turned red. He was just a student in the military academy. His parents were basic potion makers. They made a lot of potions by trading spiritual plants and were successfully admitted to the First Military Academy of the Federation.
This is all thanks to Tu Yufan, but unfortunately his current authorization authority is not high, so he can only slowly upgrade his citizenship level.
He had always suspected that Tu Yufan was not an ordinary person from the low-civilization world, because such a person had no qualifications to make a deal with Wuji Xianzun, whose current life level was at the top level even in his federation.
.......
Tu Yufan traded the information about future bulletproof vests and also gave a sample for free. Tu Yufan rubbed the fabric and it felt like ordinary clothes and there was no difference in appearance.
Five years later, the Yincheng Institute of Technology announced the discovery of room-temperature superconductor materials, which will be subsequently applied in various industries.
The next day, Tu Yufan suddenly felt a huge crisis. He dodged in advance but found that he was locked in front and behind. With a bang, Tu Yufan was hit in the chest. The huge impact threw him against the wall. He felt severe pain and several ribs were broken.
The Space-Time Mirror said calmly, "Wow, the world almost changed."
Tu Yufan touched the mark on the bulletproof vest and found it was a gun.
He almost failed in this kind of world, which really damaged his reputation.
Death in a small world would only waste destiny points. After successfully passing through so many worlds, if one still fails in a low-civilization world, he would probably be laughed at by the space-time mirror.
"It seems that I was too complacent. I must not let my guard down at any time. Even if it is a low-civilization world, I am just an ordinary person and cannot resist the sniper attack of hot weapons."
......
"Mr. Long, you didn't!?"
Police personnel discovered that the murderer used a large-caliber heavy machine gun that could fire high-explosive armor-piercing bullets and long-range sniper bullets, with amazing strength.
Tu Yufan endured the severe pain and said expressionlessly: "It's not too bad, I have several broken ribs, take me to the hospital."
“….”
Afterwards, everyone looked at the clothes in amazement. They couldn't believe that there was a bulletproof vest that could withstand heavy machine guns. The kinetic energy of heavy machine gun bullets is very large. Even if it can withstand sniper bullets, it will shock people to death.
Moreover, the clothing is so light that it doesn't look like a bulletproof vest at all.
Seeing everyone looking at him with burning eyes, Tu Yufan refused to take off his clothes.
