Arknights: Iron-Blooded Savior

Rosemary's pre-casting action was very fast, and the invisible and huge spell vortex spread around her as the center, and even rubbed against the charge in the air, forming a thin blue current fleeting.

"Go. Rosemary

raised her right hand straight and drank gently.

Buzzing——!!!!

the levitating giant weapon behind him that had been adjusted to the front suddenly accelerated to an unimaginable level in the blink of an eye, tearing the air and rushing straight forward.

Then, these four giant weapons suddenly smashed on the rock wall in front ——!!!!of them

, connecting with these four giant weapons as points, and a huge rectangle suddenly appeared!

Rosemary

closed her eyes, clasped her hands, and then gently pulled in all directions.

Rumbling ——!!!!

instant, the rock wall in front of it suddenly seemed to be swept by an invisible hurricane, and the solid rock formation was fragile like chaff cracking inch by inch, and the depth continued to extend inward.

This usually requires large drilling and blasting equipment or high-yield source stone explosives to achieve the scene, and Rosemary can easily achieve it with just a random cast.

Boom la - the rock formation disintegrates in large areas under the tearing and crushing of the spiritual entity shaped by rosemary -

but it is not irregular, no matter how rapid the process of disintegration is, it is always within the range of the four levitating giants.

In the end, it took less than five minutes for a deep probe to appear in the lower rock formation that Rosemary was responsible for, which was a rectangular cavity cut out.

"Mr. Rankopel ... The rectangular cavity is cut ... You are ready to move on to the next step.

Rosemary opened her hand lightly, and after finishing a round of surgery, she turned on Rankopel's telecommunications channel.

"Got it, now start blasting the upper rock formation, chain reaction with the cavity and adjust the pressure difference. Rankopel

on the upper level also clearly felt that the vibration under his feet had completely stopped, and it was time for him to do something.

After

finishing the communication with Rosemary, Rankopel began to install the source stone explosive according to the several positions that the Doctor had provided him, which was the side slope cut angle of the lower rectangular cavity.

At the same time as the chain reaction with the rectangular cavity, the cavity is re-modified from the rectangle to an isosceles trapezoid approximately triangular as the cross-section of the channel.

"Installation complete. "

I am a single soldier, some small rock formations gaps as the earth spirit said, slightly larger crabs are difficult to pass, and I use the source stone technique to widen it, shuttling inside the rock formation seems like a fish in water.

With the coordinates provided by the doctor, it probably took Rankopel about five minutes to install the source stone explosives.

"Detonate now. Rankopel

opened all the safety on the detonator pinned to his waist, and then slammed it on the handle three times!

With a deafening loud noise and dust raised by the explosion, after a chain reaction with !!the

rectangular cavity of the lower layer, the upper rock formation collapsed extremely quickly and merged with the lower layer.

Click....

However, because the pressure difference has not been adjusted in time, the rock structure is still somewhat unstable after the explosion, which can be heard from the small abnormal noise.

But that's not a problem for Rankopel.

Under the command of the doctor, after Rankopel used a little of his source stone skills to slightly refine some parts of the rock formation, the pressure difference between the upper and lower rock formations was completely equal.

In this way, a stable passage is just rightly carved out.

"Rosemary, the first section of passage has been confirmed to be excavated, ready to start the next section of passage.

Rankopel exhaled softly, dialed the telegram and said to Rosemary on the other end.

"Hmm... Okay, Mr. Rankopel, I'm ready to start.

The lower rosemary also answered affirmatively.

Then, under the command of the Doctor, Rankopel and Rosemary advanced synchronously between the upper and lower rock formations, and the progress accelerated greatly as they became more skillful.

Omitting large sections of parameters and details, the steps can be simply divided into -

the first step, Rosemary cuts the rectangular cavity to prepare for flashing.

In the second step, Rankopel uses a small amount of source stone explosive to carry out a chain reaction with the cavity to synchronize the development progress of the upper and lower rock formations.

In the third step, Rankopel again uses a small amount of source stone techniques to fine-tune the pressure difference between the upper and lower rock formations to ensure structural stability.

In the fourth step, go to the next node to perform the cycle of the above steps, and drill blasting again.

......

Outside, the doctor is also staring at the prototype screen all the time, and there are few parameters displayed on the screen, but the data in the doctor's heart is like an ocean wave.

...... He's calculating.

Since the doctor remembered that Preses transplanted the computing chip directly affiliated with the Tower of Babel AI in his cerebral cortex, he could feel that something in his brain was constantly stimulating and working on brain neurons with each calculation.

"Doctor, did the prototype catch an abnormal signal?"

Kelsey on the side had just finished his work and stepped forward to ask the Doctor.

"Not yet, Kelsey.

The doctor shook his head, but his hand kept stopping, and said to Kelsey:

"The current detection accuracy and detection range of the prototype are very limited, and I am constantly calibrating the available data that Parker sent us in real time." "Regardless

... Whether that outcome happens or not, we all have to be prepared. Kelsey

nodded and said

, "I know, you continue to work,

and the mobility of the command position will be ensured at all times." "

As Kelsey said, this temporary command position is quite mobile, and all Rhode Island operators communicate in the vehicle or operate from a facility right next to the vehicle.

If there is an accident, you can quickly get in the car or just turn the throttle and leave.

......

Let's switch perspectives, at this time, in the upper and lower rock formations, both Rankopel and Rosemary have just finished a drilling blast of a channel, and both agree to rest for five minutes before continuing.

However, in this limited time, Rankopel still opened the backpack and checked the source stone explosives inside, making sure that each one was not abnormal.

And although the source stone explosive in the backpack is limited by the size of the specification, it is impossible to produce a huge blasting effect.

However, with the rectangular cavity carved out by Rosemary in the lower rock formation with source stone techniques, only a small amount of source stone explosives is needed to blast, and a terrifying chain reaction can be produced.

Next, according to the doctor's instructions, use your source stone skills to refine a few cut corners and edges, and the result is that the pressure difference between the upper and lower rock formations is equal.

In this way, the upper and lower rock formations are shaped at the same time, and it becomes a vast passage with a very stable triangular equilateral trapezoid.

......

At this time, according to the efficient command of the doctor, the distance had advanced to about five kilometers, which was more than half of the total distance, and the progress along the way was quite smooth.

"There are about ten bundles of source stone explosives left, and if it goes well, according to the previous consumption, it should be used up after the last blast blows out the exit. Rankopel

opened his backpack and checked the remaining source stone explosives, secretly sighing in his heart at the doctor's ability to accurately calculate the data.

Such a long tunnel is thanks to these source stone explosives, otherwise Rankopel's own source stone skills alone would have exhausted himself to death during the 8.5-kilometer journey.

At this moment, the source stone communication machine pinned to his waist came with the signal of rosemary.

"Rosemary?"

Rankopel immediately connected the telegram, while Rosemary's voice came from the other end:

"Mr. Rankopel... The Doctor made an improvised fine adjustment of the route, and according to your bearing, it was about 30 degrees northwest and passed 500 meters. "

You go over there first, I'll finish my work and join you later..."

Rankopel said to Rosemary on the other end of the communication as he rearranged his backpack and zipped it:

"I know, Rosemary, get to the designated location at once." "

Because Rosemary had cut the cavity in the lower rock formation in advance, Rankopel was very smooth in excavating the cavity above the cavity.

This is because the source stone technique of rosemary also shakes the rock structure in the upper layer of the cavity loosely, so Rankopel only needs to use the hammer to smash hard, and the rock formation twenty or thirty meters ahead will collapse due to the chain reaction, forming its own path.

This time, he had to reach the designated area before Rosemary, so Rankopel also used the more destructive shaping of the source stone technique to open the way.

"Iron diamond!"

Rankopel drank gently, and the surrounding rock formations and free iron elements in the air responded to the call of his source stone technique, and it was stripped out of it in almost a few seconds.

The ——!!!buzz then swirled on Rankopel's right arm, expanding

in size, and the fine iron sand formed a sharp spiral, rubbing the air with a sharp sound.

Nowadays, the consumption of the complex source stone skill of iron diamonds is not more than Erer in his eyes, and both the destructive power and scale are better than his previous self.

"Here it comes!" Rankopel

directly aimed the iron diamond at the position reported to him by Rosemary, and then his footsteps jumped, and the whole person carried the iron diamond and rushed forward.

Buzz -

Iron drills are 100% professional counterparts used to dig rock formations to form channels, and the solid rock is nothing more than fragile tofu blocks.

......

At a distance of five hundred meters, it took Rankopel less than two minutes to reach the location that Rosemary had told her.

"Is there an internal space here?" But

just as Rankopel stopped the iron drill thrust, his figure suddenly lightened, and the rock formation in front of him suddenly disappeared, turning into an empty internal space.

The internal space inside this rock formation is obviously not a natural formation from the surrounding cracks, but is left by extremely strong external forces.

"Rosemary, there is an internal space in the rock formation here, did you cut it?" Lan

Keper looked at the internal space in front of him, his eyes froze, and then immediately dialed Rosemary's channel, and almost instantly was connected, and he immediately asked.

"Rankopel...

"You arrived at the designated location... And Rosemary's

voice on the other end seemed to become a little strange, and the tone began to tilt low.

"I have arrived at the location. Rankopel

replied.

And at this moment, the voice of "Rosemary" suddenly distorted:

"Mr. Rankopel ... Wow ——!!!

"" absorption. Rankopel

suddenly found that the moment rosemary's voice was deformed, an orange-red light suddenly flashed away in the back cover used by the source stone communication machine to dissipate heat.

"Very clever. And

he slammed his own force and squeezed the source stone communication machine in his hand into a ball of scrap iron.

"I'm looking for you too. "
