The flashing frame representing the lottery is constantly changing in 18 districts, which makes Liu Lei's heart also pinch up, this is Liu Lei really hates that he slept so much when he was in history class in his last life, except for knowing that the Tang Dynasty had Li Bai, Du Fu, Yang Yuhuan ......, he didn't even know what inventions the Tang Dynasty had.

The flashing cursor rotated a few times, and finally stopped on a question mark, Liu Lei's fists clenched tightly and his eyes widened, and the moment the prize appeared, Liu Lei actually had a feeling of being surrounded by a big surprise, and there were two big words of gunpowder written on it.

Gunpowder was invented in the Tang Dynasty? Liu Lei can no longer care about these, as an authentic Chinese, the prestige of the four great inventions has long been engraved in his flesh and blood.

Marx, the red mentor, once said: China's four major inventions: the emergence of papermaking and printing changed the situation that only monks could study and receive higher education, and facilitated the spread of culture;

The use of gunpowder and firearms destroyed the feudal castles and helped the bourgeoisie to defeat the feudal aristocracy;

The compass reached the hands of European navigators, making it possible for them to discover America and make it possible to sail around the world, laying the foundations for the bourgeoisie for the development of world trade and workshop crafts.

The four great inventions of ancient China have left a brilliant page in the history of human science and culture. These great inventions have influenced and benefited the whole world, pushing human history forward.

This is a big killer, Liu Lei stared at the word gunpowder and smiled stupidly, the corners of his mouth drooled and he didn't know, for a moment he thought of muskets, artillery, explosives packets, and even the name of the missile in the future, although he knew that the missile had little to do with gunpowder.

Although there are many forms of cultivation such as magic and fighting qi in the Otherworldly Continent, and the power is even greater than the power of gunpowder, it can't stand the cheap gunpowder, and it can be seen very low, so that ordinary people can also have the ability to fight against cultivators.

The most important thing is that the gunpowder produced by the system is not ordinary, but according to the improved and upgraded version of the Otherworldly Continent, using a new formula, the power has increased dozens of times, and unlike the weapons produced by the alchemists of this world, the gunpowder does not have any energy fluctuations at all before it is ignited, if you don't know even the most powerful cultivators, it will only be regarded as garbage, and it is definitely a necessary artifact for Yin people, setting traps, and digging traps.

Liu Lei could already imagine the frightened expressions of everyone in this world when a few ordinary soldiers lured a fighter-level master to a trap and ignited gunpowder.

"Good stuff! Great stuff! ”

After the lottery, the system automatically handed over the good gunpowder formula and a finished product to Liu Lei, and when Liu Lei withdrew from the sea of consciousness, he couldn't wait to open the ingredient list and look at it, the improved gunpowder formula increased from several instants on the earth to twenty-one, and they are all plants, minerals and even animal materials unique to the Yuan Continent, fortunately, Liu Lei knew a lot of materials with the identification function of the system before, plus learning from Old Man Li, the things on the ingredient list can be recognized, And they are the most common valleys with a lot of ingredients.

Liu Lei carefully put the ingredient list into his arms, this thing must be produced by a completely trustworthy person, and then Liu Lei opened the finished product in the box, only to see that the black gunpowder that was common in the previous life has become dark red after improvement, and there are some crystals, which looks a little shiny.

Liu Lei carefully took out a little bit with two fingers, put it on the table, and hid the rest under the bed, then picked up the candle next to him and carefully put it up.

Yikes!

The gunpowder was ignited in an instant, and it burned out in just a flash, Liu Lei only felt a ball of light, and it was over, and when he looked up, he saw that a fist-sized hole had been burned out of the table.

Seeing this scene, Liu Lei smiled even more, the power of gunpowder depends on the energy released by instant combustion, the shorter the burning speed, the greater the energy released, indicating that the stronger the power of gunpowder, the improved version of gunpowder is thirty times stronger than the old gunpowder of the previous earth, Liu Lei feels that it is less to say.

Although the weapons created by alchemists in the past can also give ordinary people the strength to fight with cultivators, they are not only expensive, but also require rare and precious pure energy such as precious essence stones and magic cores, which those who can afford it cannot use it, and those who can use it cannot afford it. It is not an exaggeration to have a priceless market, after all, I have never heard of alchemists on the mainland making weapons for ordinary people, and maybe only the elite troops of those big forces can be equipped with a small number of alchemy weapons that can be used by ordinary people, such as the Force Gun.

And gunpowder can be said to be a real civilian weapon, if one day gunpowder really spreads and spreads, then most of the low-level cultivators who are now powerful on the heads of ordinary people will lose their status and even their lives.

Of course, Liu Lei would not do such a thankless task, and if he did that, he would become the public enemy of the whole people in the cultivation world.

In the eyes of noble cultivators, civilians are just ants, objects that they can kill at will, even if Liu Lei is arrogantly flipping the table, he doesn't dare to do it, and now he is also a member of the privileged class.

After packing up everything, Liu Lei suddenly thought of one thing again, and said to the system in his mind: "By the way, what did you just say, what is the matter with the artificial assistance system?" ”

At this time, because the primary energy supply has been completed, the system can standby for a long time, and there is no need to worry about shutting down in a few days, so Liu Lei asked directly in his mind, and the system can also hear it.

"It's a primary artificial intelligence assistance system," the synthesized voice corrected.

"To put it simply, it can provide the host with simple computing, identification, contact and other functions, if it is not easy to understand, you can treat it as an upgraded version of your previous smart phone."

Liu Lei always felt despised when he heard this, is his comprehension really so poor!

Liu Lei thought of a test method, and said excitedly: "If I draw a figure, can you help me write it down?" ”

"Yes"

When Liu Lei heard this, he seemed to have found the door to a new world.

"Okay, you record it"

As he spoke, Liu Lei ran outside and grabbed a handful of sand and put it on the table, and began to paint the solid original pattern with his fingers. His purpose is very simple, if the system can perfectly record the process of original painting, then it is equivalent to their perfect memory of an original pattern, in the future, there is no need to contact for a long time, the system in their own body, can monitor their every stroke, every muscle action, only need the system to correct themselves in the future, want to be someone to teach themselves by hand, the success rate can be greatly increased, experience is never as good as the set program, this is to open the rhythm of the hanging.

Liu Lei was halfway through the painting, and the original pattern suddenly collapsed.

Forehead......

"Record?"

"Let's delete it" Liu Lei said helplessly, if he wants the system to record perfectly, he must first draw it perfectly.

…………

"Record?"

"Delete"

……

"Is it recorded?"

"Delete ......"

……

"Delete ......"

"Delete!"

"Delete!"

……

"Sister, don't paint and sleep, I'll talk about it tomorrow, I'm not in a good state after eating too much today" The painting reached the two hundred and fifty times, Liu Lei suddenly swept the sand on the table to the ground in annoyance, and I don't know what's wrong today, I didn't succeed once.
