Qi Fang's words reminded Zhen Fei, he said: "yes, we should also see that mysterious holy mountain. I'll let Bai Mei organize and send the grown-up boys to the holy mountain, but it seems that women are not allowed to enter there."

"If we don't go, since it's a secluded rule, we need to abide by it." Qi Fang said with a pause, "don't take women with you in your storage space."

"There's never been a woman in my storage space." Zhen Fei said.

"What about the medical staff?" Qi Fang reminded. In Zhen Fei's storage space, there are not women, but women without that kind of ambiguous relationship. In Zhen Fei's storage space, there is definitely more than one medical research institute. Zhen Fei forgot for a moment.

But careful Qi Fang remembers it.

Qi Yi said in an all embracing manner: "give me the storage space. You can go to Shenshan with empty hands to have a look, just to see it. I don't believe that Shenshan is so powerful."

At the beginning, I learned from the Teng family that not only women could not climb the mountain, but also monks could not take women to the mountain in their storage space, otherwise they would be punished by the angry gods.

Moreover, all the boys in Youjian can enter the holy mountain after the age of 14 to obtain the guidance of the gods and become monks.

It's very mysterious how the gods point out. The Teng family didn't make it very clear.

In this regard, Zhen Fei, who did not get the guidance of the gods, also became a monk, did not believe the words of the Teng family very much. Later, he heard different monks say the same thing on different occasions. He could not help but believe the truth of the words.

Only in the annual Mid Autumn Festival in August, when the moon is the roundest and brightest, can we enter the sacred mountain. Moreover, we need to walk to climb the mountain and can't fly. These rules make the sacred mountain full of mystery.

Bai Mei is the one who organized the climbing of the holy mountain. Because the young and middle-aged people who were instructed by the gods were all the targets of selecting warriors, they were also part of the military category. In other words, the young and middle-aged men were the reserve forces of the garrison of Qincheng.

Sun Yingji's experiment went very smoothly. After breaking through the extraction of five flavors of real fire, sun Yingji also found a way to extract the "spirit" from steel. According to sun Yingji, "every substance has a spirit. If you take out the spirit, you can change the characteristics of the substance."

Take out the spirit of steel. Steel loses weight and becomes transparent, like glass. Can such material have the characteristics of steel? Steel is hard and not easy to break, so it is suitable for building all kinds of utensils. Otherwise, it can be replaced by wood or rock. In fact, steel has the characteristics that stone and wood cannot replace.

Sun Yingji still injected mana into steel. The steel produced in this way not only did not lose the required characteristics of steel, but also had indestructible characteristics in hardness.

This result was unexpected by Zhen Fei. On the spot, he used a gun loaded with high explosive armour piercing bullets to shoot at the new steel, leaving only a white mark on the surface of the steel, which is only two millimeters thick. High explosive armor piercing projectiles are powerful enough to pierce 24 mm of steel.

This piece of steel is as light as a piece of paper. Then experiments were carried out at high and low temperatures to prove that this kind of steel can withstand the low temperature of - 512 degrees and the high temperature of more than 290 degrees.

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

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

That is to say, at normal temperature and in normal places, the corrosion resistance of new steel exceeds that of stainless steel and other alloys.

After witnessing the experimental effect of the new steel, Zhen Fei was overjoyed and said to sun Yingji, "is it difficult to extract the essence of steel?"

"It's not a lot of trouble. A friar can extract 100 tons of steel a day."

"That's a lot." Zhen Fei hesitated and said, "what kind of reward do you want to get? The success of this experiment will bring about a series of revolutionary changes. Your contribution to mankind is of great significance. "

"I just like to do this. If you really want to reward me, give you to me." Sun Yingji's eyes are shining at Zhen Fei, and he can no longer hide his love in his heart. This powerful man makes her adore and is the driving force for her endless exploration.

Without the support of love, sun Yingji will not go so far on this road. Scientific research is very boring, and any carelessness may make all previous efforts wasted. But once the experiment is successful, the sense of achievement is also very huge. She hopes to get Zhen Fei's love and satisfy her ideal.

Zhen Fei doesn't want to let Sun Yingji go. Without hesitation, he said, "no problem, I will marry you, but will your family agree?"

"They don't care about me. I'll make my own decisions." Sun Yingji hasn't been home for a year, and she doesn't want to. Living here in Zhenfei is very happy. She finds her own value and achieves a height that others can't do. Following Zhenfei, she has a great sense of achievement.

Both of them are practical people. In a few words, they talk about their private affairs. They are very straightforward. The process of children's love affair is completely omitted.

Zhen Fei called this new type of steel "cloud iron" and also included it in the top secret, known as the "comet II" project. Sun Yingji's experiment made a breakthrough long before he destroyed Bujia, which is rich in refined iron.

After killing the Bujia, Zhenfei obtained more iron ore. hundreds of thousands of monks dug iron ore day and night, and then were sent to the furnace to refine the best refined iron. Zhen Fei's reserve of refined iron has reached an astonishing 30 million tons, which is increasing with the increase of Qincheng's population every year.

The only place where refined iron is used in Youjian is to make heavy armor warships. The houses are all made of stone. The rest are made of wood, and there are no cars and other products. Besides, steel is needed to produce magic weapons, artifact, immortal weapons and other weapons. Therefore, the amount of steel used in seclusion is far less than that in the world.

If you want to make all the cloud iron into warships, you need at least 200000 warships to meet the needs of the existing warriors. The annual output of Zhen Fei's warships is only about 10000, which is very fast.

Thinking that it will take 20 years to replace all the troops with the warships of Yuntie, Zhen Fei also has a headache. He can only wrap a layer of Yuntie outside the existing light warships to block the enemy's attack.

Sun Yingji's contribution is undoubtedly huge. If the fire she developed is a sharp spear to attack, the discovery of Yuntie is a solid shield. In attack and defense, sun Yingji achieved breakthrough research results.

It is expected that after the cloud iron warship is produced, Zhen Fei's troops will no longer have an opponent in the dark. The solid cloud iron warship can resist the attack of immortal weapon, but the cloud iron warship can't kill the opponent, which is a great pity.

As long as we are invincible on the battlefield, we have the hope of winning.

That's what Zhen Fei thinks. The samurai's refusal to use fire to attack the enemy is also a headache for him. Zhen Fei doesn't value the little spoils of the enemy. What he needs most is strategic materials. As long as he has production capacity, everything can be made.

The other two kinds of materials that are not available in the secluded world, coal and oil, have also been excavated. The huge oil storage tanks are filled with three artifact spaces. It is estimated that the accumulation of oil will reach 200 million tons. The artifact space within a few hundred miles is densely packed with oil tanks. These oil tanks are not magic utensils. They are sealed containers made by friars with five flavors of real fire.

The monks with super ability disdain to produce this kind of oil tank. What they are most interested in is to produce magic tools and artifact, which will give them a sense of achievement. Everything that does not belong to magic tools is rubbish, and they will not understand the importance of oil. Because there are no utensils in the secluded world that need to be powered by oil.

Coal is put in the space of artifact like a hill. Even Zhen Fei frowns. So much coal may bring great disaster to the world, so it must not be put into the market all at once.

A month later, Zhen Fei ordered to stop the development of crude oil and coal, which relieved many monks and finally freed them from the dirty and tired labor. They returned to Qincheng with their wages, driving the business of brothels and casinos in Qincheng into a hot stage.

After the monks squandered their money, they started a new job. They never worried about food and clothing. The monks in the secluded world have not been worried about food and clothing since they were young. They used to spend the rest of their energy on fighting and fighting against the elves. They have been fighting all the year round, and countless people and elves have died on the battlefield.

After the production of cloud iron, it was immediately used in the most needed place, that is, the light warship of the army.

The work of going to worship the holy mountain is also ready. Bai Mei has selected more than 70000 adult men. This work is easier to do. As long as the news is released, all the boys in the family will be sent to Bai Mei. I'm afraid I've missed the selection of the gods.

The man in the family must be recognized by the gods, and then embark on the road of cultivation and become a monk with strong ability. If there is no monk in the family, it means that the living standard immediately drops, food and clothing are not enough.

Women can't climb the holy mountain, but they get the teaching of "spirit chapter" in the book of heaven from Ma Ying, and also embark on the road of cultivation, which makes many friars angry, because they find that their wives dare to speak out in front of them and no longer obey men's orders. The dominance of men in society and family is slowly disappearing.
