Forty Millenniums of Cultivation

The evacuation of the workers and families of the large iron mill is nearing its end as the new giant soldier Tianjing, who was upgraded, gradually reveals its prototype.

Countless “seeds” have been sown in dozens or even hundreds of underground towns based on a new, worry-free doctrine that has changed its philosophy. In the near future, it will inevitably be as far away as a burning dandelion, lighting up more dark places.

New Pharaoh, new ideas, new hopes… may come to this world without sunshine earlier than you think.

It was time for Li Yao and others to leave.

They discussed the contact method with Xu Zhicheng and further explored the response of the immortal in the event of a major siege.

However, Li Yao estimated that it was unlikely that the immortals would completely surround the ground.

Or the question he started talking about —— cost.

Now that the revolutionaries and the families of the four electorate emperors are on the ground, both sides are doing everything in their power to prove that they are the “Orthodox” of the Empire and to destroy each other completely.

But behind the revolutionaries is the presence of the Black Star Emperor Wu Yingqi, and the family of the four electorate emperors has scolded the empire for 500 years. Whoever wants to swallow each other's breath seems unlikely.

Apart from their special existence, the riots of ordinary people underneath the ground are really a worthless little problem. It is hard to imagine that Black Star Emperor Wu Yingqi could suck a large number of elite people to the ground in the face of the overwhelming situation of the family of four major election emperors. A tunnel then drilled through one tunnel, worked hard and worked hard to catch a few ordinary people who were blind.

“I hope you will persevere in the ground and remember our promise that, within a year and a half at most, there will surely be an astonishing battle between the heavens and the stars, and that the fairy practitioners of both factions will fight forever, and that we will come back - with a real fleet.

“That's when the underground man sees the sun again! ”

Li Yao assured Xu Zhicheng, all worry-free people and ordinary people under the ground.

They wanted to go straight back to the ground and look for the last few star harbors occupied by the families of the four elected emperors.

After all, the situation in Didu is more tense every day than it is every day. At that time, it will be very difficult to find a suitable starship to jump in the stars and seas, when the revolutionaries will have complete control of the entire polar realm.

Before we can escape, contact the righteous fighters from all over the star sea and accumulate our strength, we must mix them in while the families of the four electorate emperors are still making their final retreat.

However, when Xiaoming and Wenwen left the big iron factory, they took the main control crystal brain there, but it was okay to think of it as a toy, but they studied some strangeness.

“Daddy, Daddy, look at this. It looks like a big blueprint for the pharmacopoeia. ”

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

This blueprint was only found in an order when they broke through a secret firewall of the master crystal brain of the railway factory and parsed a deeply hidden database.

Because the construction of the firewall and the hidden pattern of the database are quite sophisticated and complex, both little guys have studied how long it takes to break through the line of defense, and they don't have to be interested in what's in the order.

“Isn't this the gear tray on the shield machine? ”

Li Yao could tell by a quick glance.

The shield machine is a tunnel digger, a large magic treasure dedicated to opening tunnels and expanding underground space. Naturally, in the underground world of iron slabs, it is an essential daily consumable.

In order to expand living space to the ground, humans refine and manipulate countless shield machines every second, digging down, digging, digging, digging, digging new factories, towns and tunnels connecting these places.

Shield machines are divided into mechanical, hydraulic, hybrid and very advanced glaucoma crushing types depending on how they work. Typically, their front ends are like a large grinding disc with a large number of drill bits and teeth. When running at high speeds, independent drill bits rotate at high speeds, iron teeth oscillate thousands of times per second, and even large grinding discs rotate at high speeds, with a multi-pronged approach, to chisel hard rock formations.

The wear rate of the drill bit, the iron teeth and the abrasive disc itself is naturally incredible when touched so hard that the relevant parts must be replaced frequently.

Therefore, most of the factories in the underground world have the full range of shield machine spare parts to refine the pipeline, as well as the large iron factory, not only can refine spare parts, even the complete shield machine can be refined, belonging to “fist products”.

There's nothing strange about finding a batch of design drawings of shield parts in a large railway factory order.

But Li Yao took another look at the dimensions of these components and found out why the two little guys were asking him with the blueprints.

The iron teeth on this batch of shield machines have reached more than five meters long and wide!

Although Li Yao is not very familiar with large civilian manipulators such as the shield machine, he still has basic common sense. He recalled several classic federal and imperial shield machine models, and found that if the length and width of the shock iron teeth reach five meters, then the entire operating surface of the shield machine, that is, the large grinding disc at the front, has a diameter of at least about 100 meters!

In other words, a hundred-metre diameter tunnel can be drilled in the rock in an instant when such a shield machine “rumbles” through!

No, if it's 100 meters in diameter, can it still be called a tunnel?

“Isn't that possible? ”

Li Yaolan mumbled and hurried to take a closer look at the order found by the two little guys.

He immediately discovered that this was not as simple as a district order, but also included a complete process flow chart, a secret formula for the matching of new alloy materials, and a sophisticated military technology transfer agreement.

For example, a regular shield machine oscillates iron teeth, the oscillation frequency is generally 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 will not be able to withstand, and it will soon become bald and scattered.

But this… The shock iron teeth used by the mega-shielder actually have to be shaken more than 12,000 times per second to meet the performance parameter requirements!

The production process of such high frequency oscillations is naturally not available in large iron factories.

So this secret database contains a lot of information on how to make it, and even a few experts - without the disruption of Li Yao and others, these experts will be coming to the big railway factory shortly to personally improve the process and guide local refiners and workers.

The harder the refined material that shakes the teeth, the higher the frequency of shaking, the more robust the formation can naturally be crushed, or the efficiency of excavation can be greatly improved.

Raising a shock knife one or two meters long to 10,000 shocks per second is quite a complicated technique, let alone five or six meters of iron teeth, to operate under extremely harsh conditions.

This is state-of-the-art military technology. It is by no means a "three-family slave” such as Li Minghui is eligible for mastery.

Li Yao's hands were running like flights, and a technology transfer agreement and refining process flow chart were opened. In addition to shaking iron teeth, there were impact drill bits and components of some hydraulic system that had to be refined in a large railway factory.

Li Yao is an all-encompassing "drill bit expert”, but he was also deeply shocked by the working principles and refining methods of such drill bits.

Although the secret database contains orders and refining authorizations for only a few Fargo components, such as iron teeth, drill bits, etc., Pew Panther, Li Yao can also perform roughly, how huge, robust and horrible the ultimate supermassive shield machine is!

It's not a shield machine, it's a giant steel beast that devours the core!

“Take a look at the creation time of this secret order and refining agreement, as if Li Minghui betrayed the Orientalist family and turned to the Li family shortly afterwards. ”

The text says, "Especially when the three powerful gods of the moon arrive underground, and this secret database comes in with a lot of critical data, they seem to be trying to refine a lot of similar components here! ”

“Exactly. ”

Li Yao estimated that if all of the refining process transformation and technology transfer mentioned in the database could be completed, the entire large railway plant would operate at full capacity, constantly refining a large number of shock iron teeth and impact drill bits, and supplying… a dozen supermassive shield machines would operate day and night without problem.

A dozen supermassive shield machines with operating surfaces hundreds of meters in diameter, while advancing?

The immortal, more precisely Wu Yingqi, what exactly is he trying to do?

Li Yao immediately consulted with Longyang Jun and Li Jialing.

“In other words, Wu Yingqi and Li Linghai's people occupy the big iron factory, not just to serve as a forward base for our capture, but really need the big iron factory to help them refine a fairly critical set of pharmacopoeia? ”

After listening to Li Yao's analysis, Longyang Jun went back and forth and looked at the information found by the two little guys for half a day, concluding.

“Yes, there is no reason to bring down so many Royal Forest Army elites just to hunt us down and catch Li Jialing. ”

Li Yao said, "The so-called human sea tactics only make sense when there is a vast battlefield that can fully open the line of fire, and the immortal repairer can't be without a prophet, knowing that we will blood the big iron factory.

“If pursuits and counter-attacks are carried out in winding, narrow, asphyxiating tunnels and crevices, the number and significance of which are small, will instead become a burden of consumables and blocked passages.

“The Moon is a double-hunter witch, skilled in diving assassinations, barely a helper; the Royal Forest Army is good at frontal combat, just to hunt us down, there is no need to bring these people.

“And don't you think they seem to have a little more material stored in the big railway factory, rather than carrying out a temporary pursuit mission, but staying here for a long time? ”

“Seems so. ”

Dragon Yang Jun nodded thoughtfully, “I was also strange when raiding the big railway factory. Is the moon devil insane? Why did he bring down so many royal army elites just to chase us?

“If they are on two missions, one is to hunt us down, the other is to host a large railway factory and help it complete a comprehensive technical upgrade and refine the pipeline, and then supervise the release of a batch of key Pharaoh components, perhaps escorting them to the location of the supermassive shield machine - that makes sense! ”
