Luo Zhongfa slowed down a little and responded:

"Gamma ray metal detectors can detect the inside of metal, but now we only have one, and we will intensify our search for such equipment in the future, or use a medical gamma knife to modify it to see if it can be used."

Han Chenggang nodded after hearing this, and said slowly:

"Well, this matter is very important, you Director Shihua will coordinate well and get the refining department up as soon as possible."

"In addition, some time ago, the effect of the large-scale military training was good, and we must continue to strengthen the training in this area, especially the sword formation, which must be run in more, and it will be of great use in the future."

"In the training, we must screen out a batch of good seedlings, and give priority to the construction of runes to the guild, Hua Yan, you have to dock with President Shi in this matter!"

"Yes, Uncle Han!"

Hua Yan simply agreed.

Han Chenggang looked at Luo Zhongfa again at this time and said:

"Director Luo, we still have nearly 100,000 soul powers, and one or two million ordinary people, now we can produce ordinary mechanical armor, and we can use mechanical armor to arm them all in the future, and with combat vehicles, new aircraft, new laser cannons, and ion cannons, we can completely build an army that adapts to the new environment."

"Of course, this will put a huge pressure on your logistical supply, but if we want to survive well, we must work hard to overcome all difficulties to build this army!"

Luo Zhongfa stood up at this time, saluted Han Chenggang with a military salute, looked serious, and shouted categorically:

"Yes! Heads! Mission completion guaranteed! ”

Han Chenggang nodded towards Luo Zhongfa and continued:

"We human beings can't just perish like this, and we can't live under the ground like rats all the time, why do we want to build this steel city, that is, to let human beings live in the last days in the same world, don't be reluctant, we must stand on this earth with dignity and live openly!"

Hua Yan and Shi Yushan were also infected by Han Chenggang's emotions, and they both stood up and nodded solemnly.

This is a life-and-death threshold, no one can slack off, and after the meeting, all the work is unfolding rapidly.

Luo Zhongfa's efficiency was very high, and in less than two days, the refining department was built, directly occupying the first floor of the building left behind after the Light and Dark Alliance left.

And recruit the first batch of more than 20 soul people with experience in equipment building.

At Hua Yan's special request, Shi Meng was recruited by name, and by the way, he got his two apprentices and the equipment of the blacksmith shop to the refining department.

The only gamma-ray metal detector was also moved.

Although the refining department was initially established, the time was tight and the task was heavy, Hua Yan didn't give them much time to adapt, and soon started the construction work.

Now Hua Yan's soul golden Buddha still has about half left, and it is estimated that he can still make seven or eight regular style swords, and he took them out and donated them to the refining department.

The soul gold that needs to be used in the follow-up He arranged for Hong Zhan to select some soul energy people with relatively large soul energy cracks to recuperate, and then the refining department purchased them at a high price.

The "Kun" character text has been shared by Hua Yan to an exclusive area on the brain network, and the people in the refining department can refer to the rune structure through the exclusive password.

For this reason, a can of brain tissue was specially transferred to the refining department to connect the brain network, and now everyone has realized the importance of brain networking.

Hua Yan first explained the process of building to the more than 20 people, as well as some precautions for building runes inside the sword.

For Hua Yan, he has sufficient soul energy, and the strength of his soul energy has reached more than five hundred kilograms, but these people are not good, many things that are easy in Hua Yan's opinion, others are difficult to do.

After the preparations were completed, Hua Yan decided to take Shi Meng to build it once, after all, he had observed it twice with him before and had some experience.

Shi Meng began to build for the first time, and did not choose other rare materials, but chose bronze, which is relatively easy to smelt.

Hua Yan didn't take action personally, he just guided Shi Meng on the side.

The melting temperature of bronze is about 1,000 degrees Celsius, which can be achieved by ordinary furnaces.

Shi Meng did not have the ability to directly manipulate the smelted bronze with his soul energy to directly shape it, but first used a mold to pour the smelted bronze into shape.

While pouring and molding, his two apprentices took the smelted soul gold, used soul energy to pull it into gold wires, and then made it into a form similar to the "Kun" character script, and then threw it into the bronze juice that was being poured into the sword.

With the assistance of a gamma-ray metal detector, Shi Meng could observe the form inside the Soul Gold Silk Bronze Juice, and then he began to use his Soul Energy to control the Golden Silk to construct two "Kun" characters in the bronze sap.

This process is easy to say, but for Shi Meng, this process of constructing runes is extremely difficult, because his soul energy strength and accuracy are not enough.

Repeated many times, Shi Meng failed.

In the end, in desperation, Hua Yan still asked Shi Meng to imitate the method of the ancient swordsmith, first let the bronze juice cool down and become a sword blank, and then assist the detection of gamma-ray metal detectors to construct runes by constantly hammering the sword blank with the help of the combination of external force and soul energy.

Although this is a little slower and more cumbersome, it can save a lot of soul energy.

In the end, after seven or eight days of repeated beating, the first bronze rune sword was successfully crafted by Shi Meng.

After the bronze rune sword was successfully built, the entire refining department was jubilant, and Hua Yan also let out a long breath.

Then Shi Meng began to build the second one, this time Hua Yan did not participate again, with the first successful experience, it only took five days for Shi Meng to build the second bronze rune sword.

Seeing that the work of the refining department was gradually on track, Hua Yan handed over the affairs of the refining department to Shi Meng to be responsible.

Later, he also transferred this stall to the logistics department, and after knowing that the work of the refining department was carried out smoothly, Han Chenggang and Shi Yushan were also very excited.

Being able to build a large number of rune weapons to assist more soul people to build runes is the cornerstone of improving the strength of the Steel City.

During this time, the entire Steel City was in a state of high speed, and almost everyone was busy.

Now the production of mechanical armor in charge of the logistics department has also entered mass production, and more than 2,000 have been produced, and these mechanical armor has also become the standard equipment of the rune powerhouses in the guild.

After obtaining Shi Yushan's consent, Hua Yan handed over the complete "Mo Family Sword Spectrum" to Hong Zhan through the brain network, and he had been using this to train soul powerers recently.

The elaboration of the Mo family's sword technique in "The Mo Family Sword Spectrum" is more accurate, and Hua Yan particularly values the explanation of the potential and meaning in the Mo family's sword formation, if Hong Zhan can lead these soul people to train out the Mo family's sword formation, then it will not be without the power to fight against the demon beasts at that time.

Hong Zhan also quickly realized Hua Yan's intentions, so the training was also very harsh, and the candidates for the sword formation were also extremely strict.

Hua Yan had also recently begun to cultivate that "Flood Desolation Tyrant Body Technique" in his free time, although it had some impact on his soul energy rift, but it was not very big, it just made his soul energy rift expand a little slower.

Now he was also a lot more relieved, but the process of cultivation was too painful, almost like peeling skin and removing bones, polishing the body from the cellular level, and the material energy penetrated into the cells, which was extremely destructive.

Most of these cells will directly disintegrate and die, and a small number remain, so that the cells of the whole body will be replaced through cultivation to enhance the strength of the body.

This process is fine for the limbs and these organs, but for the fragile brain tissue and microvessels, it is simply a repeated cycle on the verge of death.

No wonder Hua Yan hadn't seen anyone cultivating this in his Divine Palace image, this kind of torture was really not something that normal people could endure.

However, this "Flood Wilderness Tyrant Formula" can be inscribed on the ancient tripod with Zhong Ding script like those I Ching runes, and it must have an unusual status.

Now is a critical moment for the survival of human beings, no matter how hard and difficult it is, he must continue to cultivate, and he will not let go of every opportunity to improve his strength.

After cultivating the "Flood Desolation Overlord Body Technique", Hua Yan also discovered an advantage, that is, his "Extreme Dao Sword Technique" was easier to cultivate.

After the physical strength increased, his "Extreme Dao Sword Technique" was quickly upgraded to the first level, and the "Extreme Dao Sword Technique" itself was a martial art that squeezed the potential of the human body, while the "Flood Desolation Hegemony Body Technique" increased the strength of the body, and these two martial arts actually complemented each other, which was beyond Hua Yan's expectations, and also surprised him.

The steel city is now gradually entering the track of rapid development, but there are two main bottlenecks now.

One is oil, and the other is that the brain network has not been fully rolled out now, after all, the jar of brain tissue brought by Hua Yan is far from enough.

Hua Yan is going to go back to Hope City, bring back the equipment for drilling for oil, and prepare to open oil fields, but the current situation can only develop those shale oil by the sea, which is not possible in Steel City.

In addition, he plans to bring some rare metal materials and monster materials from the Iron City back to Hope City to improve the strength of Hope City.

If the trade route between the two cities can be opened, it will be of great benefit to both Hope City and Steel City in the future, and the strength of both sides can be quickly improved.

At that time, a large number of brain tissues can be transported, so that nearly two million human beings in the steel city can be integrated into the brain network, the scientific research and organizational mobilization ability of the whole city is a geometric exponential improvement, and the oil field can also supply the development of the two cities at the same time after exploitation, so that the bottleneck can be completely broken and the overall strength can be raised to a higher level.

However, since the last time the steel city grain transport troops were attacked by monsters, there has been no large-scale operation outside the city, from the steel city to the hope city is nearly three hundred kilometers, and there is a monster forest in the middle that cannot be bypassed.

If you want to bring oil drilling equipment and other equipment and materials, you need a large fleet, and it is impossible to avoid the monsters.

It seems that the only way to kill is to go back.

Hua Yan clenched his fists and secretly made up his mind.

Then let's fight our way out!
