Forty Millenniums of Cultivation

When the upgraded new giant soldier "Tianjing" gradually revealed its embryonic form, the evacuation work of the workers and family members of the big ironworks was nearing completion.

Based on the new worry-free teachings that have changed the concept, countless “seeds” have been spread to dozens or even hundreds of underground towns. In the near future, they will inevitably float like flaming dandelions and light up. More dark places.

New magic, new ideas, new hopes... Maybe come to this sunless world earlier than you think.

When Li Yao and others are leaving.

They discussed the liaison method with Xu Zhicheng and further explored the countermeasures for the cultivation of the immortals.

However, Li Yao estimates that it is unlikely that the immortals will completely encircle the ground.

It is the cost of the problem he said at the beginning.

Now the ground-based reformists and the four electorate families are in full swing. Both sides are doing everything they can to prove that they are the "orthodox" of the empire and completely destroy each other.

But behind the reformists, there is the existence of the black star Emperor Wu Yingqi. The four electorate families are five hundred years of the empire. No matter who wants to swallow the other party, it seems unlikely.

In addition to the special existence of them, the riots of the ordinary people in the underground are really worthless. It is hard to imagine that the black star Emperor Wu Yingqi can also draw a large number of people in the face of the army of the four electors. Elite to the bottom of the ground, a tunnel and a tunnel to drill through, do the hard work and live, just to catch a few ordinary people who are unremarkable.

"I hope that you can persist in the promise of the ground. Within a year and a half, the extreme heavens and the celestial stars will definitely have an earth-shattering battle. The two faction cultivators will fight until they die, and at that time we will also Come back with a real fleet.

"That is, when the underground people see the sky again!"

Li Yao assured Xu Zhicheng, all the worry-free believers and the ordinary people in the underground.

They originally wanted to go straight back to the ground to find the last few Star Harbors occupied by the four electorate families.

After all, the situation in the Imperial Capital is getting more and more tense every day. Seeing that the reformists must completely control the entire heavenly world, it is very difficult to find a suitable starship to jump in the Xinghai.

It is necessary to smash the four major electorate families while they are still in the final retreat, and then they will have a chance to escape, contact the people around the Xinghai, and save their strength.

However, Xiao Ming and Wen Wen took away the master crystal brain there when they left the big iron factory. Nothing was considered as a toy, but they were researched by some.

"Dad, Dad, look at the design of this magic weapon, it seems very big!"

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

The design is that they broke through a secret firewall of the big iron factory master crystal brain, and solved a hidden database, which was found in an order.

Because the construction of the firewall and the hidden mode of the database are quite sophisticated and complex, the two little guys have studied it for a long time before they break through the line of defense. They are not interested in the things in the order.

"Is this not the sprocket on the shield machine?"

Li Yao casually glanced at it and saw it.

The shield machine is a tunnel boring machine. It is a large magic weapon specially used to open tunnels and expand underground space. It is an essential daily consumable in the underground world of iron plates.

In order to expand the living space to the bottom of the earth, human beings refine and manipulate countless shield machines every minute, dig down, dig, dig, and dig new factories, towns and tunnels connecting these places.

According to different working principles, the shield machine is divided into mechanical, hydraulic, hybrid and very advanced smashing. Generally speaking, their front end is like a large grinding disc with a large number of drill bits and iron teeth. During operation, not only the independent drill bit will rotate at high speed, the iron tooth will oscillate at a frequency of several thousand times per second, and even the large grinding disc will rotate at a high speed, and the multi-ply can be used to cut a hard rock formation.

In such a hard and hard competition, the wear rate of the drill bit, the iron tooth and the grinding disc itself is naturally very amazing, and the relevant components must be replaced frequently.

Therefore, most of the magic weapons factories in the underground world have a complete assembly line of spare parts for the shield machine. The same is true for the big iron factory. Not only can the components for the preparation be refined, but the complete shield machine can be refining, which is a fist. product".

It is not surprising that a batch of shield machine components were found in the orders of the big ironworks.

But Li Yao glanced at the size of these components and knew why the two little guys had to ask him with a design.

The iron teeth on the shield machine have reached more than five meters in length and width!

Although Li Yao is not familiar with civil large magic weapons such as shield machines, but the basic common sense is still there, he reminisced several federal and imperial classic shield machine models, and found that if the length of the iron teeth is shocked, If the width is up to five meters, then the entire working surface of the shield machine, that is, the top of the large grinding disc, the diameter is at least 100 meters!

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

No, if it is 100 meters in diameter, can it be called a "tunnel"?

"Is this impossible?"

Li Yao muttered, and hurriedly took the orders that the two little guys found to look carefully.

He immediately discovered that this is not as simple as an order, but also includes a complete refining process flow chart, a matching recipe for new alloy materials, and a sophisticated military technology transfer agreement.

For example, the oscillating iron teeth of the ordinary shield machine generally have a frequency of 3,000 to 5,000 times per second. If the frequency is high, the material strength of the iron teeth and the structure of the shield machine itself cannot withstand. It will soon be bald and scattered.

But this...the super-large shield machine uses the oscillating iron teeth, the performance parameters require to reach 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 lot of methods of how to refine, and even the information of several experts, if there is no confusion of Li Yao and others, these experts will soon come to the big iron factory to personally improve the process. To guide local refiners and workers to work.

The harder the refining material of the oscillating iron tooth, the higher the oscillating frequency, naturally smashing the stronger rock formation, or greatly improving the efficiency of the tunneling.

Raising a one- or two-meter shock turret to 10,000 vibrations per second is a fairly complicated technique, let alone a five- or six-meter iron tooth, and it must work under extremely harsh conditions.

This is the most advanced military technology, and it is by no means qualified by Li Minghui, the "three surname slaves".

Li Yao’s hands are flying like a fly, and he has opened a technical transfer agreement and a refinery process flow chart. In addition to the shocking iron teeth, there are also impact drills and some hydraulic system components that must be placed in the large ironworks. .

Li Yao is a "drill expert" who is uncompromising, but he is also deeply shocked by the working principle and refining method of this drill bit.

Although the secret database contains only orders for iron weapons, drill bits, etc., and orders for refining, but in the tube, Li Yao can also roughly perform, and the huge shape of the super giant shield machine is huge. Majestic and horrible!

This is not a shield machine, but a steel behemoth that swallows the core!

"Looking at the creation time of this secret order and refining agreement, it seems that Li Minghui betrayed the East, and soon after he turned to Li."

Wen Wen said, "In particular, the three great gods who are unparalleled in the month have come to the bottom of the earth. This secret database has flowed in a lot of key data. They seem to be refining many similar components here!"

"Yes."

Li Yao estimated that if the refining process transformation and technology transfer mentioned in the database can be completed, the whole big iron factory will be full of horsepower, and a large number of shocking iron teeth and impact drills will be continuously produced. ... More than a dozen super-large shield machines are not a problem for day and night operations.

More than a dozen super-large shield machines with a working surface diameter of 100 meters, and rumbling forward?

The immortal, more accurately, is Wu Yingqi, what exactly does he want to do!

Li Yao immediately asked Long Yangjun and Li Jialing to discuss.

“That is to say, Wu Yingqi and Li Linghai’s people occupy the big iron factory, not only to serve as a base for arresting us, but to really need a big iron factory to help them refine a group of fairly magical components. Hey?"

After listening to Li Yao’s analysis, Long Yangjun turned over and looked at the information found by the two little guys for a long time, summing up.

"Yes, if you just want to chase us and catch Li Jialing, there is no reason to bring so many Yulin troops."

Li Yaodao, "The so-called human tactics only make sense when the space is vast, can fully spread the fire line, and the immortals are not likely to know the prophet, knowing that we will smash the big iron factory.

"If the pursuit and counter-attacks are carried out in twists and turns, narrow suffocation tunnels and gaps, the number of people is much more, and the significance is not great. Instead, it will become a burden of consuming materials and blocking passages.

"Monthly unparalleled hunting witch, proficient in stealth assassination, barely a helper; Yulin Jun elite is good at frontal combat, just to chase us, there is no need to bring these people.

"And you don't think that the materials they store in the big ironworks seem to be a little more. It is not like performing a temporary killing mission, but staying here for a long time."

"It seems like this."

Long Yangjun nodded thoughtfully. "I was very surprised when I raided the big iron factory. Is it true that the month of the month is mad? Just to chase us, why do you bring so many Yulin troops to be elite?"

"If they are performing two tasks, one is to chase us, the other is to station the big iron factory, and help the big iron factory to complete a comprehensive technical upgrade and refining assembly line transformation, and then supervise the release of a batch of key magic weapon components. Perhaps it is okay to **** this batch of magic weapon components to the super giant shield machine!" rw
