Little Hela used more sophisticated instruments to measure the material in detail when it was taken back to Sirius, updating its nomenclature to say that it was not so much an alloy as a synthetic crystal, and the processing technology contained in the titanium crystal material was amazing.

Today's federal science and technology, although it has made great achievements on the road of exploring artificial isotopes, is still unable to produce materials with such metamorphosis performance.

Materials science is an extremely complex discipline that is fraught with a great deal of uncertainty.

For a single element, it has different physical properties at different temperatures, volumes, crystal structures and multiphase states, and multi-element composite metal base alloys are already very complex.

And all the technologies of this base high-energy weapon defense layer titanium polymeric crystal material used by this alien advanced civilization are even more incredible. Using the artificial isotopes of titanium as the base material, the combination of dozens of isotopes of other elements, and the use of advanced processing technology unknown to HELLA to produce such a material with excellent performance.

Under simple density determination and multi-clock temperature monitoring, the density of the material is 7.23 at room temperature of 300K, and the thermal conductivity reaches the extreme at 1000K high temperature, with a value of more than 10,000.

In addition, it has good vibration transmission performance, which is a property inherent in its crystal properties, and can also be used as an excellent crystal oscillator raw material.

After chemical testing in multiple states, there is finally some good news.

Titanium polymer crystals are highly oxidation resistant, high temperature resistant, strong acid corrosion resistant, and the normal properties are extremely stable, and the only weakness is that it is not resistant to strong alkali corrosion at low temperatures, which is the conclusion reached by Xiaohella after a large number of chemical tests.

The general reaction principle is that under the low temperature condition of about 100K, the internal crystal structure begins to be alienated, and the atomic structure of several added elements that are not resistant to alkali is exposed, and the reaction occurs in the alkaline environment, which finally leads to the loosening of the overall structure of the material, and the surface layer of the titanium polymerization crystal is peeled off.

After repeated tests, Little Hella determined the conditions for the optimal reaction rate and the alkaline solution used, and quickly adjusted the outpost chemical production unit for production.

As for the means of cooling at low temperatures, it is of course the classic liquid nitrogen, which Sirius's own air handling equipment can accomplish this task, only by continuously compressing air in the high-pressure reaction chamber.

However, at such a low temperature, the alkaline solution needs to take other polar proton solvents, and the water-based solvent will condense due to the low temperature, which will affect the reaction effect.

After the rapid production of the solution solution for the titanium polymerization crystals, the various reaction materials required were put into production, and the reaction equipment used was also modified after Hella generated the processing drawings.

As long as the demand conditions are determined, HELLA can use its own huge industrial database to complete the complete process of design, manufacturing and production, and at the same time optimize the allocation of resources to approach the theoretical optimal value of industrial efficiency.

"Sister Luoshen, the estimated operation time is 13 hours, and you can implement a chemical damage plan for the titanium polymerization crystal protective layer."

Little Hela passed on her progress data to Roselle, while also presiding over the cold destruction of the defenses.

It is to use the ADNR drill bit to drill out the hole on the protective layer little by little, and then use kinetic energy impact drill a little bit to dig the protective layer, because of its crystal structure characteristics, compared with the ultra-high hardness, the material as a whole is still a bit "brittle", that is, the toughness is insufficient, and it is easy to break in response to strong impact.

It's a pity that compared to the excellent physical properties of the titanium polymer crystal itself, the impact force provided by the Hella Star's spider mecha holding a modified large impact drill is still a little worse, and it took half a day to smash a palm-sized piece from the protective layer, with such an efficiency, the thickness of tens of meters can make her busy for thousands of hours, so the current destruction operation is mainly to explore the internal functional structure of the protective layer.

Soon, Roselle made a new discovery.

"Hela, turn up the high-powered microscope, do you see these subtle channels?"

Hela quickly leaned over her titanium electronic eye, carefully observed the protective layer section, observed for a while, and used more refined ultrasonic detection methods to re-examine the protective layer.

"The smallest diameter of these pipes is only tens of microns, no wonder they cannot be detected by low-frequency long-wave oscillation monitoring, and the structure of these capillary pipes is very similar to that used to transport heat transfer media."

Little Hella quickly guessed that these capillary pipes should be used for those with superfluid-like heat conductivity in the flow of heat conductive media, and in some pipes with a diameter of millimeters, Hella also found some powder residues.

The powder was transported to an open space underground, which had been filled with a large amount of equipment and became a simple nearby testing laboratory, because it was more troublesome to transport the Sirius back every time, and after the relevant transformation of the underground world was completed, Hella brought in a lot of equipment to build this forward laboratory, and the current underground environment is more suitable for the needs of the laboratory than the surface environment, shielding a lot of external interference.

Electron tunneling microscopy revealed the remaining gray-black powder.

"Sister Roselle, these things nanobots! The main atomic structure is the same as that of titanium polymeric crystal material, and it should be the nanotechnology used for the repair of the protective layer. ”

Roselle's simple analysis, combined with these analyses, gives a general understanding of the current means of defense of the protective layer.

"Is it possible to use energy conduction and nano-repair technology to locate the defensive layer of high-energy strike protection? Hela, can you detect how long these nanobots are dormant?"

"Okay, oops, I didn't notice a lot of oxidation damage just now, sister, wait a minute, I'll do vacuum protection."

Due to its nano-scale microscopic state of existence, nanorobots have significantly weakened their ability to resist external interference, and are rapidly oxidized by oxygen in the air.

Little Hella can only test these nanobots, which are made of titanium isotope atoms as the main material, after taking vacuum storage measures.

Using the half-life calculation, Hella obtained a time identification of 560,000 standard years.

"Sister, the half-life of these nanobots is about 1296 standard hours, and based on the current radiation levels, the existence time has been 560,000 standard years."

"The means of nanorobot transportation and energy supply, which should be the protective layer, failed a long time ago, so these nanorobots remain in the transportation pipeline."

Little Hela looked at the originally smooth protective layer, but now it has been destroyed by the drill bit and percussion drill.

"If the nanobots work properly, the damage should be repaired by itself soon."

The use of nanomeans to repair materials, which is the main achievement of Federated Technologies' nanotechnology today, and Hela, who understands its technical principles, quickly deduced the energy supply location of these nanorobots.

As long as the nanobots composed of the same substrate are used, it is normal to complete some operations similar to the reunion of broken mirrors in today's federation, which reveals an information point.

"In this case, little Hela, at least the repair method of this protective layer is still within the theoretical range, it seems that this base is only much more advanced than the Federation, but it has not yet reached the unknown level."

"Do you have more high-hardness drill bits? It's too slow. ”

Roselle calculated the time, with the current means of destruction, it would take hundreds of calibrated hours of water grinding to open a hole with a diameter of less than one meter, and to dig a tunnel of the same size, Hella directly gave an incomplete. Relying solely on the means of physical destruction, the existing supply of high-hardness drill bit consumables is simply not enough, and the production process of PCBN materials with higher yields, Hella, has not yet been launched, and this time it is impossible to count on.

We can only wait for the low-temperature alkali corrosion scheme to go online.

Luo Shen calculated the three-dimensional data of his prosthetic limbs, and thought about it carefully, their main goal now is to enter this base, not to destroy this protective layer, so the operation goal should also be reset.

The current target for Hella is still a tunnel-level task, which is obviously too demanding.

"Hela, how long does it take to punch a 40 centimeter diameter penetration hole with a low temperature alkali corrosion solution?"

"A 40-centimeter penetrating hole, well, it takes about 20 hours to prepare the equipment, and it is estimated that it will take 23 hours to penetrate it. But we can't get into such a small hole. ”

Little Hela was a little puzzled, such a small passage hole could transport some detection robots into it at most, and there were obviously other layers of defense behind the protective layer, what could it detect.

"That's enough size, Hela, these capillaries must have a main channel inside the defenses, can you detect it?"

Roselle didn't say anything about his intentions, and asked Little Hela's detection technology if it could find the main channel of these capillary circulation pipes, which was much more effective than the two of them brute force to penetrate.

"Yes, the cavity features I detected these things, the internal structure simulation has been generated, Sister Roselle, there is a valve device similar to a circulation node here, where the main channel is about 20 centimeters in diameter."

"There are deeper parts that cannot be detected, and they are beyond the detection range."

In the holographic model of the protective layer structure projected by the bridge, a large number of capillaries pass through the detectable protective layer, showing obvious modular characteristics, which converge into a node device in a fixed area, and then pass through a larger diameter pipe to the depth.

"It turned out to be modular assembly, and then the technical way of nanorobot connection, but how to solve the energy supply of nanorobots, and where is the energy supply device?"

According to the modular features presented by the structural model, HeLa directly saw the construction of the protective layer, but there seemed to be no trace of the energy supply unit in the model.

"Little Hela, have you forgotten the room-temperature superconductivity of this layer of defense? It itself can provide free electron energy to those nanorobots. ”

"Okay, I've been led astray by you again, I mean you use these ready-made internal channels to speed up the progress and find the main interface behind, as long as you break through this protective layer, even a 20 cm channel is enough."

Roselle's carrier tapped on the skull of Helastar's skull and looked at the pair of titanium electronic eyes.

"Wouldn't it be better if we disassembled the carrier and then assembled it slowly?"

"yes, anyway, just send the action carrier in, okay, I'll make a carrier modification plan."

Roselle's reminder made Xiao Hella instantly think of a lot of ideas, they only need to let the intelligent offline carrier enter the base, and then regularly upload data to the channel mouth wired.

"Then, let's just modify some non-human form carriers."

"I remember Sister Roselle seemed to have said that there was a story in which the shape of a creature was quite suitable for the characteristics of this mission."

"What's it called?"

Thinking about it, Little Hela linked to Roselle's database to find the answer.
