Qi Fang's words reminded Zhen Fei, and he said: "Yes, we should also see the mysterious sacred mountain, and I will ask Bai Mei to organize it and send the adult boys to the sacred mountain, but it seems that women are not allowed to enter there."

"We're not going, since it's the rules of the netherworld, we need to abide by it." Qi Fang paused and said, "Don't bring women in your storage space." ”

"I've never had a woman in my storage." Zhen Fei said.

"What about the paramedics?" Qi Fang reminded. It's not that there are no women in Zhen Fei's storage space, but that there are no women who have that kind of ambiguous relationship, and there is definitely more than one medical research institute and other institutions in Zhen Fei's storage space. Zhen Fei forgot about it for a while.

But the attentive Qi Fang remembered this incident.

Qi Yi said in a big way: "Give me those storage spaces, you go to the Divine Mountain empty-handed to have a look, just to see it, I don't believe that the Divine Mountain has so much power." ”

At first, the news I learned from the Teng family was that not only could women not climb the sacred mountain, but also that the monks could not carry women up the mountain in their storage space, otherwise they would be punished by the angry gods.

In addition, all the boys in the dark room can only enter the mountain after the age of 14, receive the guidance of the gods, and become monks.

How the gods instructed was very mysterious, and the people of the Teng family did not say it very clearly.

In this regard, Zhen Fei, who became a monk without the guidance of the gods, did not believe the words of the Teng family very much, and later he heard different monks say the same thing on different occasions, and he couldn't help but believe the authenticity of these words.

Only during the annual Mid-Autumn Festival in August, when the moon is at its fullest and brightest, you can enter Mount Kinabalu, and you need to walk to climb the mountain, not fly, these rules make Mount Kinabalu full of mystery.

The person who organized the climb of the sacred mountain was Bai Mei, and since the young and middle-aged people who received the guidance of the gods were the objects of selection of samurai, they also belonged to the military category, that is, the men who became in the prime of life were the reserve army of the defenders of Qincheng.

Sun Yingji's experiment went very smoothly, and after breaking through the extraction of the five flavors of true fire, Sun Yingji also found a method of extraction from the steel, and extracted the "spirit" in the steel. According to Sun Yingji: "All matter has a 'spirit', and after the spirit is withdrawn, the properties of the substance can be changed. ”

If the spirit of steel is extracted, the steel loses its weight and becomes transparent, a glass-like substance, can such a substance have the properties of steel? The characteristics of steel are hard, and it is not easy to break to meet the construction of various utensils, otherwise it can be replaced by wood or rock, in fact, steel has the characteristics of stone and wood that cannot be replaced.

Sun Yingji still injected mana into steel, and the steel produced in this way not only did not lose the properties needed for steel, but also had indestructible properties in hardness.

Such a result was unexpected by Zhen Fei. He shot the new type of steel on the spot with a gun loaded with high-explosive armor-piercing rounds, leaving only a white mark on the surface of the steel, which was only two millimeters thick. The high-explosive armor-piercing projectile was powerful enough to shoot through twenty-four millimeters of steel.

This piece of steel is as light as a piece of paper, and then experiments were conducted at high and low temperatures, which proved that such steel can withstand low temperatures of minus 512 degrees Celsius and high temperatures of more than 2,900 degrees.

At atmospheric pressure at room temperature, the melting point of gold is 1064 degrees, this new type of steel has such a strong plasticity, which shocked Zhen Fei's heart, it seems that the creativity of science and the magic of monks is far beyond people's cognition.

Later, this kind of steel was immersed in hydrochloric acid, boric acid, sulfuric acid, nitric acid for experiments, and it was found that only sulfuric acid with a very corrosive concentration of 95% would cause damage to this kind of steel, and in the real world, only the concentration of sulfuric acid would reach that high for industrial chemical raw materials.

That is to say, at room temperature, in a normal place, the new type of steel exceeds the corrosion resistance of alloys such as stainless steel.

After witnessing the experimental effect of the new type of steel, Zhen Fei was overjoyed and said to Sun Yingji: "Is it troublesome to extract the steel spirit? ”

"It's not a lot of work, a monk can extract a hundred tons of steel in a day."

"That's a lot." Zhen Fei hesitated for a moment and said, "What kind of reward do you want to get?" The success of this experiment will lead to a series of revolutionary changes, and your contribution to humanity will be of far-reaching significance. ”

"I just love doing this, and if you really want to reward me, give it to me." Sun Yingji's eyes looked at Zhen Fei intently, and he could no longer hide the love in his heart. This powerful man makes her fall in love and is the driving force behind her endless exploration.

Without the support of love, Sun Yingji would not have gone so far on this road, scientific research work is very boring, any slightest sloppiness may make the effort become wasted, but once the experiment is successful, the sense of achievement is also very huge. She hopes to get Zhen Fei's love and meet the ideals in her heart.

Zhen Fei also didn't want to let go of a talent like Sun Yingji. Without hesitation, he said: "No problem, I will marry you, but, will your family agree?" ”

"They don't care about me, I'll be in charge of my own business." Sun Yingji hasn't been home for a year, and she doesn't want to go home either. Living here in Zhen Fei is very happy, finding the value that belongs to her, and achieving a height that is difficult for others to achieve, and following Zhen Fei is very fulfilling.

Both of them are practical people, and they talked about private matters in a few words, very neatly, and the process of children and children was omitted.

Zhen Fei called this new type of steel "Cloud Iron", which was also listed in the top secret, and was called the "Comet II" project. Long before the destruction of the cloth family, which was rich in fine iron, Sun Yingji's experiment made a breakthrough.

After killing the Bu family, Zhen Fei obtained more iron ore, and hundreds of thousands of monks dug iron ore day and night, and then was sent to the furnace to smelt the best fine iron. Zhen Fei's reserves of refined iron have reached an astonishing 30 million tons, a figure that increases production every year with the increase in the population of Qincheng.

The only place where fine iron is used in the Netherworld is to make heavy armor warships, the houses are all made of stone, the rest are wood, there are no products such as cars, and then there are some weapons such as magic weapons, artifacts, and immortal weapons that require the use of steel. Therefore, the amount of steel used in the netherworld is much lower than in the human world.

If you want to make all the cloud iron in your hand into warships, you need at least 200,000 warships to meet the needs of the existing samurai. And Zhen Fei's annual output of warships is only about 10,000 ships, which is already very fast.

Thinking that it would take twenty years to replace all the troops with Yuntie's battleships, Zhen Fei also had a headache, so he could only put a layer of Yuntie on the outside of the existing light warships to block the enemy's blows.

Sun Yingji's credit is undoubtedly huge, and if the magic fire she has researched is to attack a sharp spear, Yun Tie's discovery is a strong shield. In terms of offense and defense, Sun Yingji has achieved breakthrough research results.

It is expected that after the Yuntie battleship is produced, Zhen Fei's troops will have no opponents in the dark world, and the sturdy Yuntie battleship can withstand the attack of the immortal weapon, but the Yuntie battleship cannot kill the opponent, which is a big pity.

As long as you are invincible on the battlefield, you have the hope of victory.

Zhen Fei thought like this, the refusal of the warriors to use magic fire to attack the enemy also gave him a headache, Zhen Fei didn't value the little loot on the enemy, what he needed most was strategic materials, as long as he had production capacity, anything could be made.

The other two kinds of materials that are not used in the dark world, coal and oil, have also been excavated a lot, and the huge oil storage tank fills the three artifact spaces, and the accumulation of oil is estimated to reach 200 million tons, and the artifact space within a radius of several hundred miles is densely packed with oil tanks. These oil canisters are not ritual vessels, but sealed vessels made by monks with the five flavors of true fire.

The monks with super abilities are very disdainful of producing this kind of oil canister, they are most interested in the production of magic weapons, artifacts, which will give them a sense of accomplishment, everything that does not belong to the magic weapon is garbage, they will not understand the importance of oil. Because there is nothing in the dark room that needs to be powered by oil.

Coal is placed in the space of the artifact like a hill, and even Zhen Fei frowned, so much coal may bring huge disasters to the world, and it must not be put into the market at once.

A month later, Zhen Fei ordered the development of crude oil and coal to be stopped, which made many monks breathe a sigh of relief, and finally freed themselves from that kind of dirty and tiring labor, and they returned to Qincheng with their wages, which led the business of Qinglou and casino in Qincheng to enter a booming stage.

After the monks had squandered the money in their hands, they began to work again, and they had absolutely no worries about food and clothing. The monks of the Netherworld have not worried about food and clothing since they were children, and they used to spend their remaining energy on fighting, conquering the elves, and they have been fighting all year round, and countless people of the human race and the elven race have died on the battlefield.

Let's say that after the production of Yuntie, it was immediately used where it was needed most, that is, on the light warships of the army.

The work of going to worship the sacred mountain has also been prepared, Bai Mei has selected adult men, a total of more than 70,000 people, this work is easier to do, as long as the wind is released, all the boys in the family will take the initiative to send it to Bai Mei. I'm afraid I'll miss the selection of the gods.

The men of the family must be recognized by the gods, and then embark on the path of cultivation and become powerful monks, if there are no monks in the family, it means that the standard of living will immediately drop, and there will be no food and clothing.

Women were not allowed to climb sacred mountains, but they received the teachings of the Spirit Chapter in the Book of Heaven from Ma Ying's hands, and they also embarked on the path of cultivation, which annoyed many monks, because they found that their wives dared to speak loudly in front of them, and they no longer obeyed the orders of men. The dominance of men in society and the family is slowly disappearing.
