Chapter Seventy-Nine: Into the Moho Surface

After the apostle disappeared, a 30-kilometer radius was designated as a military control zone, and all major roads were guarded by soldiers and armored vehicles, and traffic was prohibited. Pen & Fun & Pavilion www.biquge.info

Usually, there is basically no one else in this volcanic area except for travelers and adventure lovers, but I didn't expect the volcanic eruption to be too loud, attracting many people to see the freshness, as well as a large number of news reporters, but unfortunately all of them were intercepted.

In fact, ordinary people could not get close to the center of the explosion for 5 kilometers, because it was full of toxic gases and volcanic ash, and it was like a layer of gray snowflakes and a thick layer of accumulation within a radius of more than 10 kilometers.

"Yes, concentrate your mind and spread the AT force field under your feet......"

Under Shinji's persuasion, the second machine lying on the ground finally unfolded the AT force field in the horizontal direction, although the posture was a little ugly.

"Wow~" Unexpectedly, the No. 2 machine turned over and slipped to the ground, if there is no precise control, stepping on the AT force field is like stepping on a smooth plane, and it can't stop at all.

Although she has fallen countless times, Asuka still gritted her teeth and persevered, she has a tenacity in her heart that does not admit defeat, which Shinji appreciates very much.

Shinji and Asuka squatted in EVA for a week without finding any trace of the Apostle, and the first machine even ventured deep into the bottom of the lava without finding any clues. He knew very well that the apostle was not dead at all, but had turned into a shrunken turtle and did not know where to hide. This guy's attack power is not good, maybe he knew that he would be beaten up, so he simply shrank his eggs.

After persisting for a while, Shinji and Asuka could only return to the Earthquake Research Institute dozens of miles away to rest.

"Asuka, let's grill chicken wings on skewers, grilled with molten magma from the volcano, the flavor is so unique that most people can't eat it. ”

Shinji handed over the skewers, the hot oil still bubbling and mixing with the sauce, giving off a rich meaty aroma. Because of the volcanic eruption, the magma erupts along the cracks in the rock, and the grill on it can be used for magma barbecue, but it is more dangerous.

"Can you eat this?" Asuka looked skeptical.

"Wait, the lava roast is likely to be contaminated with toxic gases and heavy metal vapors, let me test it first. Ritsuko passed by with a folder and stopped Shinji's flattering behavior in time.

"Didn't you? I wrapped it in tin foil. ”

This is what Shinji has been working hard for a long time in a heat-insulating suit, and when he takes off his clothes, he is already a water man, and he can pour sweat in his boots.

"That's not a guarantee of absolute safety, so you can fill your stomach with this first. Ritsuko threw a sandwich to Shinji and Asuka each.

On the grounds of food safety, Ritsuko confiscated all of Shinji's skewers and went back to her room to eat beer with Misato.

"Ritsuko, you're so bad, you didn't leave some for Shinji. ”

"It's okay, didn't he spoil us last time. I didn't expect this kid to be so good......" Ritsuko buried her head in nibbling on the chicken legs.

"How's it going, or nothing?"

"Although emergency equipment was called in and staff risked their lives to drill, nothing was found. ”

At the same time, in the final dogma area of the NERV headquarters, drillers are drilling holes in the ground day and night, using drill bits made of super alloys, which can withstand temperatures of 4,000 degrees Celsius, but 34 of them have been scrapped regardless of wear and tear.

"At present, the drilling depth is 3,228 meters, and the predetermined position has been reached. A mud-covered NERV staff member reported.

"Now that you've crossed the Conrad plane, it's time to place the gravitonometry scanner. Dongyue ordered.

"Yes!"

"Does that work?" asked Lao Akira with a dark face, having just been sprayed in disgrace by the Human Completion Committee.

"Thankfully, because the site is buried deep underground, we have saved 13 kilometres of drilling distance, and if we have time, we can even penetrate the crust to reach the Moho face. ”

The earth's crust is divided into two layers, the upper granite layer and the lower basalt layer, and the seismic waves between the two layers change slightly, and there is a secondary discontinuity - the Conrad plane. The seismic wave accelerates on this surface, and the longitudinal wave (P wave) increases from about 5.6 km/s to about 7.6 km/s, and the shear wave (S wave) increases from about 3.2 km/s to about 4.2 km/s.

This acceleration indicates an increase in density and hardness in the layer below this surface. The average chemical composition above this surface is similar to that of granite (density of about 2.7 g/cm3), and the layer below is similar to that of basalt (density of about 2.9 g/cm3), so the Conrad surface becomes the interface between the "granite layer" and the "basalt layer".

Through the basalt layer, you will reach the Moho surface, that is, the interface between the earth's crust and the mantle, and below is molten magma, the temperature is as high as 1200~1300 degrees Celsius, and of course, there is a high pressure of tens of thousands of atmospheres, which is an environment that can generate diamonds.

"Start the detector and start collecting data ......"

"Data collection complete!"

"What are the results of the Magi analysis?"

"The Moho side directly below the headquarters is being eroded at a speed of about 300 meters per day, and we have less than 27 days to prepare. ”

"Does basalt bottom invasion rule out?" refers to the partial melting of the underlying basalt layer into the mantle.

"It has been ruled out, and the erosion points are very concentrated. ”

"Tell Katsuragi Sansa to come back with Dr. Akagi, along with the two EVAs. Lao Jie ordered.

"Yes!"

Inside the office.

"This is a trouble, Lilith must not be transferred, because the entire Final Dogma Zone is a sealing array. "Dongyue is worried.

"Also, the large number of N2 bombs that have been planted must also be moved, and it is very dangerous if the battle breaks out below. Lao Iki said.

If the bomb is triggered in the battle, the entire headquarters will definitely be blown up to the sky, and all of Lao Jie's plans will come to naught, which he will never allow.

……

"What??," Shinji and Asuka were surprised.

"Yes, although there are no analysis patterns, the rock formation 8 km below the main site is being eroded. ”

"Do we have any weapons to use?"

"Unfortunately, there aren't many weapons to deal with enemies underground, unless ......"

"What?"

"It may be possible to use a hydrogen bomb with a yield of hundreds of millions of tons to detonate in underground rock formations. ”

"What are you kidding, if it causes a super earthquake, then half of the RB will sink on the ground, right?" Asuka shuddered at the thought of that scene, she had already experienced the power of a small nuclear bomb explosion, or an enhanced version of a volcanic eruption.

"So it's up to you for now. ”

"Perhaps...... I can try. Shinji remembered some of the pit daddy weapon.

On the weapon test field, there is a huge cannon barrel, which is a temporarily repaired positive electron cannon, yes, the semi-finished product that was blown up before has now been pulled out again after repair.

If he had a choice, Shinji would never want to touch this weapon again, because it was too cheating, and it had the hidden attribute of 800 self-damage before injuring the enemy.

"Is it really possible to wrap the compressed positive electrons with an AT force field and then emit them with a magnetic field?"

"So let's experiment first. Ritsuko's glasses glowed with cold.

"Start charging...... 10、9、8…… 2, 1, 0, launch!"

As soon as the first machine pressed the trigger, I saw a thin line brighter than the sun shoot out, reaching the distant mountain, and then as soon as it passed through, the bright line continued to move towards the sky, and finally produced a violent explosion, and the white strong light emitted almost obscured the sunlight, like launching a small sun.

"What expensive fireworks. Shinji sighed.

"Very well, the penetration of the AT force field is as strong as expected, somewhat similar to neutrinos. Ritsuko's eyes lit up as she looked at the experimental data collected on the screen.

Of course, neutrinos can pass through lead several light-years thick, and the AT force field is not at the same level as the penetration of such anti-celestial particles.

However, Shinji can control the timing of the release of the cation electron by controlling the intensity, phase, and frequency of the AT force field, which requires extremely high accuracy and an error of more than a dozen nanoseconds.

Too soon or too late, the positive electrons will immediately annihilate and release energy when they come into contact with matter, which must be released when approaching the apostles.

After several experiments, it was finally discovered that the biggest problem at present was that the strength of the AT force field condensed by Shinji was insufficient, and it was impossible to penetrate too thick strata, and it was already the limit to enter more than 340 meters underground.
