Chapter 2427 Mysterious Order

When the upgraded brand-new giant soldier "Tianjing" gradually took shape, the evacuation of the workers and their families of the big iron factory was also coming to an end.

Based on the brand-new Wuyou Cult with a changed concept, countless "seeds" have been sown to dozens or even hundreds of underground towns. What a dark place.

New magic weapons, new ideas, new hopes...maybe come to this sunless world earlier than imagined.

It was time for Li Yao and others to leave.

They discussed the method of contact with Xu Zhicheng, and further discussed the countermeasures in case of a large-scale encirclement and suppression of immortal cultivators.

However, Li Yao reckoned that it was unlikely that the cultivators would completely encircle and suppress the underground.

It's still the cost of the problem he mentioned at the beginning.

Now the reformist faction on the ground and the four major elector families are fighting in full swing, and both sides are doing everything they can to prove that they are the "orthodox" of the empire and completely eliminate each other.

But behind the reformers was the Black Star Emperor Wu Yingqi, and the four major elector families had dominated the empire for five hundred years. No matter who wanted to swallow the other party, it seemed impossible.

Except for a few of their special existences, the riots of ordinary people in the underground are really a small problem that is not worth mentioning. It is hard to imagine that the Black Star Emperor Wu Yingqi can mobilize a large number of people in the face of the army of the four major elector families. The elite went underground, drilling through one tunnel after another, doing all the hard work and dirty work, just to catch a few inconspicuous ordinary people.

"I hope you can stick to your promise underground. Within a year and a half at most, there will definitely be an earth-shattering battle between the Jitian Realm and the Tianji Star. The immortal cultivators of the two factions will definitely fight to the death. Come back with the real fleet.

"Then, that's when the underground people will see the light of day again!"

Li Yao assured Xu Zhicheng, all Wuyou believers and underground ordinary people.

They originally wanted to go directly back to the ground to find the last few starports occupied by the four major elector families.

After all, the situation in the imperial capital is becoming more and more tense every day. Seeing that the reformists are about to completely control the entire polar world, it will be very difficult to find a suitable starship to jump into the star sea at that time.

It is necessary to mix in the four major elector families while they are still making their final retreat, so as to have a chance to escape, contact the righteous men all over the Xinghai, and accumulate their own strength.

However, Xiaoming and Wenwen took away the main control crystal brain there when they evacuated the big iron factory, and they were studying it as a toy, but they discovered some strange things.

"Dad, Dad, look at the blueprint of what kind of magic weapon component this is, it seems to be very big!"

When Li Yao and others were about to leave the ground, two little guys came to Li Yao with a blueprint.

This design drawing was found in an order after they broke through a secret firewall of the main control crystal brain of the big iron factory and parsed out a deeply hidden database.

Because the structure of the firewall and the hidden mode of the database are quite sophisticated and complicated, the two little guys had to study for a long time before breaking through the defense line. They couldn't help but become interested in the things in the order.

"Isn't this the sprocket on the shield machine?"

Li Yao could tell with a casual glance.

A shield machine is a tunnel boring machine. It is a large magic weapon specially used to open up tunnels and expand underground space. In the monolithic underground world, it is naturally an indispensable daily consumable.

In order to expand the living space underground, human beings refine and manipulate countless shield machines every second, digging down, digging, digging, digging out brand new factories, towns and tunnels connecting these places.

According to different working principles, the shield machine is divided into mechanical type, hydraulic type, hybrid type and very advanced Xuanguang crushing type. Generally speaking, their front end is like a large grinding disc equipped with a large number of drill bits and iron teeth. During operation, not only the independent drill bit will rotate at high speed, but the iron teeth will vibrate at a frequency of thousands of times per second, and even the large grinding disc will rotate at high speed. The hard rock formation can only be cut through a multi-pronged approach.

In such a head-to-head contest, the wear rate of the drill bit, iron teeth and grinding disc itself is naturally very alarming, and related parts must be replaced frequently.

Therefore, most of the magic weapon factories in the underground world have complete refining lines for shield machine spare parts, and the same is true for large iron factories. Not only can spare spare parts be refined, but even complete shield machines can be refined. product".

It is not surprising to find a batch of design drawings of shield machine components in the order of the big iron factory.

But Li Yao glanced at the size of these components again, and he knew why the two little guys came to him with the design drawings.

The iron teeth on this batch of shield machines are over five meters in length and width!

Although Li Yao is not very familiar with civilian large-scale magic weapons such as shield machines, he still has basic common sense. He recalled several classic shield machine models of the Federation and the Empire, and found that if the length of the vibration iron teeth, If the width reaches five meters, then the entire working surface of the shield machine, that is, the large grinding disc at the top, has a diameter of at least 100 meters!

In other words, if such a shield machine "rumbles" over, a tunnel with a diameter of 100 meters can be drilled in the rock formation at once!

No, with a diameter of 100 meters, can it still be called a "tunnel"?

"Is this impossible?"

Li Yao muttered, and hastily took a closer look at the order that the two little guys had found.

He immediately discovered that this was not as simple as just an order, but also included a complete set of refining process flow charts, secret recipes for the ratio of new alloy materials, and a sophisticated military technology transfer agreement.

For example, the oscillating iron teeth of an ordinary shield machine generally have an oscillation frequency of 3,000 to 5,000 times per second. If the frequency is higher, the material strength of the iron teeth and the structure of the shield machine itself cannot bear it. Soon it will wear out and fall apart.

But this... the oscillating iron teeth used by the ultra-giant shield machine, the performance parameter requirements are so high that it must oscillate more than 12,000 times per second!

Such a high-frequency oscillation production process is naturally not available in large iron factories.

Therefore, this secret database contains a large number of refining methods, and even the information of several experts. If there is no trouble from Li Yao and others, these experts will come to the big iron factory in the near future to improve the process in person. , to guide the local refiners and workers in their operations.

The harder the refining material of the vibrating iron teeth, the higher the vibration frequency, which can naturally crush stronger rock formations, or greatly improve the efficiency of excavation.

It is quite a complicated technique to upgrade a one-two-meter-long vibrating sword to 10,000 times per second, let alone a five- to six-meter-long iron tooth, which must be operated under extremely harsh conditions.

This is the most advanced military technology, and it is by no means qualified to be mastered by a "family slave with three surnames" like Li Minghui.

Li Yao's hands were running like flying, and he opened a copy of the technology transfer agreement and the refining process flow chart. In addition to the oscillating iron teeth, there are also impact drill bits and some hydraulic system components that must be smelted in the big iron factory. .

Li Yao is an out-and-out "drill expert", but he was also deeply shocked by the working principle and refining method of this drill.

Although the secret database only contains orders and refining authorizations for a few magic components such as iron teeth and drill bits, Li Yao can roughly deduce how huge the final super-giant shield machine will be. , majestic and terrifying!

This is not a shield machine, but a steel behemoth devouring the earth's core head by head!

"Looking at the creation time of this secret order and refining agreement, it seems that it was not long after Li Minghui betrayed the Dongfang family and joined the Li family."

Wen Wen said, "Especially when Yue Wushuang and other three Huashen powerhouses came underground, this secret database has flowed in a large amount of critical data. They seem to be refining many similar components here!"

"That's right."

Li Yao estimated that if all the refining process transformation and technology transfer mentioned in the database can be completed, then the entire large iron factory will be at full capacity, continuously refining a large number of oscillating iron teeth and impact drill bits, supplying ...It is not a problem for more than a dozen super-giant shield machines to work day and night.

More than a dozen super-giant shield machines with a diameter of hundreds of meters on the working face, rumbling forward at the same time?

The cultivator, more precisely Wu Yingqi, what on earth does he want to do!

Li Yao immediately consulted with Long Yangjun and Li Jialing.

"That is to say, Wu Yingqi and Li Linghai's people occupied the big iron factory not just to act as a forward base to arrest us, but really need the big iron factory to help them refine a batch of quite critical magic weapon components me?"

After listening to Li Yao's analysis, Long Yangjun went through the information found by the two little guys over and over for a long time, and concluded.

"That's right, if it's just to hunt us down and capture Li Jialing, there's no reason to bring so many elite imperial guards down."

Li Yaodao, "The so-called crowd tactics are meaningful only in a vast battlefield where the line of fire can be fully spread out, and it's impossible for a cultivator to predict that we will fight for a big iron factory.

"If the pursuit and counterattack are carried out in winding, narrow and suffocating tunnels and gaps, no matter how many people there are, it will be meaningless, and it will become a burden that consumes supplies and blocks passages.

"Yue Wushuang's witch hunter is proficient in stealth assassination, barely a helper; the elite imperial forest army is good at frontal combat, and there is no need to bring these people just to chase and kill us.

"And don't you think that they seem to have a little too much material stored in the big iron factory? It's not like performing a temporary hunting mission at all, but they want to stay here for a long time."

"It seems so."

Long Yangjun nodded thoughtfully, "I was also very surprised when I raided the big iron factory, is the 'Moon Demon' Yue Wushuang crazy, just to chase and kill us, why did he bring so many elite imperial guards down?

"If they carry out two tasks, one is to chase us down, the other is to garrison the big iron factory, and help the big iron factory to complete a comprehensive technical upgrade and refinement line transformation, and then supervise the release of batches of key magic weapon components , and perhaps escort these magic weapon components to the location of the super giant shield machine, which makes sense!" rw
