Everyone agreed to go to the operation site of the super giant shield machine to find out, but there was only such a mysterious order in the main control crystal of the Da Iron Factory. The oscillating iron teeth and impact drill bits had just begun to be refined, and after the refining was completed, the coordinates of which side should be sent.

Li Yao estimated that Wu Yingqi or Li Linghai had no reason to share such a confidential matter with "three-family slaves" like Li Minghui. Li Minghui's large iron factory was only responsible for refining consumables, and the subsequent transportation work should be carried out by those elite imperial guards.

Even the elite Imperial Guards may not know where the refined consumables will be sent to. Only a very small number of senior officials and confidants such as "Moon Demon" Yue Wushuang knew about it.

Although Li Yao did not know the exact coordinates, he could roughly infer it.

"The large iron plant is just a very ordinary mining, smelting, energy and refining complex. Although it is large in scale, it has not high technical content."

Li Yao pondered, "You look at these technology transfer agreements and expert guidance manuals. These things are enough to show that if you want to refine qualified consumable parts, you need to invest a lot of manpower, material resources and time to upgrade several main magic weapon components of the Da Iron Factory, which is very labor-consuming.

"In the underground world, there are many heavy industrial towns like the Da Iron Factory, which have higher technical content and more complete facilities than here. Even though the ore veins here contain a variety of rare metal components, there is still a considerable gap with the demand for shock iron teeth and impact drill bits, and many raw materials have to be transported from the outside world.

"So, why did Wu Yingqi and Li Linghai choose such an "unpretentious" underground heavy industrial town to refine and process the consumables they must have?

"I think the only answer is that the location where they conduct secret operations of secret operations must be not far from the large iron plant, and there must be tunnels or mines that can be directly reached, and it can transport a large number of consumables without any obstacles."

“Even so, the search range is too large.”

Long Yangjun said, "The underground rock formation is not as good as the ground world. Nothing can be seen at a glance. The divine thoughts are often blocked by rocks and interfered by spiritual veins. It is extremely time-consuming and energy-consuming to thoroughly search every mine, tunnel and gap within a radius of hundreds of miles or even thousands of miles.

"Don't forget that Wu Yingqi and Li Linghai will conquer the last stronghold of the four major electoral emperors' families in the Pole Star at any time. Once they really control the entire imperial capital, if we want to escape, the difficulty will be increased by at least a hundred times!"

"This is a big problem, let me think about it...with it, shock!"

Li Yao's eyes lit up and said, "I don't know that Wu Yingqi and Li Linghai have controlled several super giant shield machines and dug and explored at least three or five underground units. Should they have it?

"The shield machine will shatter and annihilate the rocks, making deafening noises, and of course it will also transmit various vibration ripples, not to mention that three or five super giant shield machines will operate at the same time!

"Since we are sure that their distance is not too far, just lock in their vibration ripples and you can follow the clues to find them!"

Long Yangjun thought for a long time and said, "The idea is good, but the underground world itself has countless vibration waves. The vibrations emitted by the air circulation and cooling systems of underground towns. The rumbling sounds emitted by the shield machines of other towns and factories, including natural seismic waves caused by faint geological changes... Thousands of intricate ripples are entangled together, and when they are transmitted here, they have become very small. How do you lock in the vibration ripples emitted by the super giant shield machines? This is as difficult as finding a drop of water in a flood!"

Therefore, they must master the trump card of the Black Star Emperor Wu Yingqi, and at least they must see clearly what this trump card looks like, and only after they escape from the imperial capital can they have the capital to play.

After unifying the opinions, Li Yao and the two little guys calmed down and devoted all their computing power to the modeling and calculation of the super giant shield machine.

After all, the shield machine is a civilian magic weapon. No matter how large the size is, the structure has not undergone essential changes. It is not complicated compared to the military magic weapon. For Li Yao, who has dismantled and modified more than 20 or 30 giant god weapons, it is naturally a piece of cake. Not to mention, there are two little guys with extremely large databases to help!

However, it took them a lot of effort to refine the "vibration wave scanning and grabbing magic weapon", mainly because the accuracy requirements are too high, and many components must be polished one by one by Li Yao.

From modeling, calculation to refining magic weapons, it took more than twenty hours in total, and a strange magic weapon was refined.

In fact, there is no question of "refining". It is simply made up of search magic weapons on the giant god weapon. Time is tight, and it doesn't care about the layout and appearance. At first glance, it is a mess of metal cow dung, but four huge metal bowls extend out, and Li Yao buckles one by one on the relatively smooth rock wall. The air inside is first drained, and then injected into a highly sensitive gas that he specially modulated and acts as a conductive medium.

"Bobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobobo

"Didi!"

"Doududududududududu!"

When he held his breath and gradually injected his spiritual energy into the magic weapon and pushed his sensitivity to the limit, hundreds of ripples that were crisscrossing in the rock formation were immediately released, intertwining into absolute noise that could not be distinguished by human ears.

Li Yao patiently entered the ripple feature library one by one by one by one by him and the two little guys. Sure enough, he found the angle slightly downward twenty degrees southwest. There was an extremely weak ripple, and the overlap rate of a ripple they calculated in the feature library reached more than 95%!

"You see, this zigzag structure with ripples and overlapping zigzags means that there are more than one sound source that is created, and it is only released by several super giant shield machines working together."

Li Yao pointed to the three-dimensional model of the ripples, and the crests and troughs, explaining to Long Yangjun and Li Jialing, "There is more important point. Every three and a half minutes, the oscillating ripples fall into the bottom of the valley. It will take about two minutes before gradually rising. After another two minutes, it reaches the peak. This is obviously the cooling time of the super giant shield machine.

"According to my calculations, the temperature of such a high-power super-giant shield machine must be extremely high during operation, and it is impossible to continuously drill and crush. Three and a half minutes to four minutes are the limit, and then it must be cooled for two or three minutes before the second round of operation is carried out.
