When He Wei crossed over, the scientific and technological level of the world he was in was already extremely developed. Pen~Fun~Pavilion www.biquge.info Every citizen will implant an electronic chip under their scalp when they are born. This electronic chip, called a virtual computer, is used to enhance the brainwave signals of the implanted person.

When ordinary people go online, they directly connect to the Internet through enhanced brain waves, and read and upload information in their minds, without the need for a physical computer at all.

Only in the military, or in some federal agencies, do "old" appliances such as physical computers remain.

Because the physical computer is not only better than the virtual computer in terms of performance, but its firewall is much better than the virtual computer. For the military and federal agencies, the use of physical computers ensures maximum confidentiality in the storage and transmission of information.

The wrist computer in He Wei's hand is a special laptop computer made by the military. To use it, simply enter the correct password by voice to turn on the computer. When not in use, it is an "ordinary" wrist guard.

The shell of this wrist computer is made of the hardest T-05 alloy, and it is fully capable of the role of armor when fighting. And the built-in state-of-the-art artificial intelligence system can detect the user's vital characteristics and calculate the user's current physical condition.

Once it is found that the user's life is in danger, or if the correct voice password has not been received for more than a month, the intelligent system will automatically destroy the first-level (confidential or above) documents in the computer and send a distress signal at the same time.

"Since this wrist computer has fallen into Yin Shuo's hands, it is obvious that the first-level documents in it have been destroyed, but I don't know if there are other things entered in it. If there is a thermal weapon blueprint in it, then you don't have to worry about not having the ability to protect yourself!"

Although He Wei wanted to open the computer to check the documents in it now, reason told him that he must not do this! After all, he was now in the Haoyue Auction House, and it was very likely that Yin Shuo's eyeliner was hidden in the dark.

Once Yin Shuo's people discover the true purpose of the wrist computer, then don't worry about leaving safely with this computer!

He Youqiang pressed the excitement and curiosity in his heart, with a very calm smile, took a very calm step, and walked into the box where the jumping beads and others were very calmly.

"Young Master, you're back!"

"He Gongzi. ”

"Have you fallen into the toilet?

"Vulgar! Dengtu girl!" He Wei choked Lan Xiang with a smile, turned around and asked, "Is it ours?"

"No!" Lan Xiang replied angrily, "Oh, I wouldn't have come if I knew it was so boring!

"Won't it be a missed auction?" asked He Wei in surprise. He frowned and looked out, just in time to see two officers carrying a large bucket down, so he casually asked, "What's in that bucket?"

"It is an essential oil extracted from demon beasts, and it is said to be used as fuel. Biho replied.

"Oh, animal fat, isn't this thing cheap, can it also be put up for auction?" He asked worriedly.

Bihe shook his head and said, "He Gongzi doesn't know, animal fat is animal fat, and essential oil is essential oil. Although both are extracted from demon beasts, they are not the same thing and cannot be confused. ”

After Bihe finished speaking, seeing that He Wei still didn't seem to understand, he continued to explain: "Animal fat is the oil condensed by boiling the fat on the demon beast, and the essential oil is the oil obtained by refining and processing animal fat. Animal fat is in lumps, while essential oils are more like water. ”

"Oh, one liquid and one solid!" He said worriedly.

"Liquid, solid, what is that?" asked Bihe.

"Uh, nothing. He Wei felt that now was not the time to explain this, so he changed the topic and said, "Since the essential oil is extracted from animal fat, it must be better to burn than animal fat?"

Seeing that He was reluctant to explain what liquids and solids were, Bihe didn't dwell too much. She replied softly: "If it is good or not, it is naturally better to burn essential oils." ”

Hearing this, His eyes lit up, and he immediately thought of the internal combustion engine. At the beginning, He Wei had considered skipping the steam engine and directly manufacturing the internal combustion engine, but because there were no liquid fuels such as kerosene and diesel in this world, the manufacture of the internal combustion engine could not be carried out.

Now that this liquid fuel, called essential oil, has been found, the manufacture of internal combustion engines is certainly not a problem.

"Look, look! It's a match! It's finally our turn!" Lan Xiang's cheers interrupted He Wei's train of thought, and caused everyone to turn their eyes to the auction table.

"It's a new type of fire fold, called a safety match! It's safer, more convenient, and not afraid of water than ordinary fire folds! Even if you accidentally get wet with water, as long as you dry it, you can still use it!" said the auction's host, "For people who go out a lot, this safety match is a must-have to carry around!"

"Does it work underwater?" someone asked aloud.

"This ...... I'm afraid not. The host replied.

"Can it be used on a rainy day?"

"As long as it doesn't get wet, you can use it. The host said.

"Isn't that just unusable? And said it's not afraid of water?"

"Uh...... The host of this ......" was slightly embarrassed.

He Wei frowned and complained, "Didn't you say that Haoyue Auction House was the best auction in the empire?

"That's right, what is this guy doing? Is it going to be a bad shot for our matches?" Lan Xiangwen said angrily.

Xiangzhu sighed and said, "No way, didn't he say it just now?" The auctioneer is not there, he just came up to replace him temporarily. ”

"The auctioneer isn't here, so where did he go?" asked Ho.

"I've kept you waiting! I'm sorry, I'm sorry! Yin Shuo is the head of Haoyue Auction House and the chief auctioneer of the bank. I'm sorry for the delay in a little thing just now. ”

Without waiting for the women to answer, a loud voice suddenly sounded, and Yin Shuo, who was full of spring breeze, suddenly walked onto the auction table and waved his hand to drive the person on the stage down.

"Okay, don't talk nonsense, let's continue today's auction!" Yin Shuo said, "This safety match is actually a new invention of He Gongzi." It abandons the materials and processes used to make old-fashioned fire folds, and uses a safer and more reliable ......"

Yin Shuo pointed to the safety matches on the stage and talked eloquently, saying that even He Wei himself had almost forgotten how the safety matches were made.
