Thanks to SK.CDC, the elves dancing in the night, and the winning monthly pass——

Foam gold, the full name of foam metal. It is a new type of material with a large number of pores distributed in the metal matrix, like foam. According to the structural characteristics of pores, it can be divided into open-cell foam and closed-cell foam.

Metal foam has two elements: first, the material contains a large number of pores; Second, the contained pores are used to meet some or some special design requirements to achieve the expected performance indicators. Metal foam not only retains the characteristics of structural materials such as lightweight, high strength and high temperature resistance, but also has the characteristics of new materials such as energy absorption, heat insulation, shock absorption, flame resistance, heat resistance and good permeability.

"Can you resist the attacks of the lizardmen?" This is what Wu Chen cares about the most.

"Yes. We used a three-layer composite structure consisting of an upper composite panel, a low-density foam sandwich and a bottom composite panel to create a 'light alloy foam sandwich'. It has a lot of advantages:

First, the density is low and the specific stiffness is higher (a higher specific stiffness means that the material is lighter at the same stiffness). The sandwich structure can not only meet the requirements of strength and stiffness of structural parts, but also meet the needs of energy absorption characteristics.

Secondly, the damping characteristics are excellent. When the vibration occurs by external force, the foam metal sandwich will be forced to expand and contract with the panel, reduce the vibration energy, reduce the vibration, and at the same time, a small range of sliding can be produced between the foam metal sandwich layer and the panel under the action of vibration pressure, and additional interface damping will be generated, so that the energy of the vibration will be further reduced.

Finally, it has excellent thermal insulation and sound insulation. Closed-cell metal foam has a low thermal conductivity, and at the same time, the multi-void structure can absorb sound and reduce noise. ”

With the introduction of the chairman. Wu Chen gradually had some impressions of metal foam. Before the end of the world, this seems to be a very high-end, cutting-edge technology. The most famous should be aluminum foam. I don't know what high-grade alloys they have developed into metal foam after so many years.

"Carbon fiber nitinol foam sandwich."

"The upper and lower layers of composite panels are carbon fiber, and the sandwich layer is titanium-nickel foam." Wu Chen understood. The Arsie sisters' keel armor contains a large amount of titanium-nickel alloy, a magical memory alloy that can automatically heal after being transformed.

"The nitinol foam sandwich inherits the memory of titanium-nickel alloy and can gradually recover after stress deformation. The same rigidity underneath. The weight is only 1/5 of that of titanium. The chairman smiled.

"That's a good one." In other words, with a weight of 4 tons, you can have the same capacity as a double-decker car, and the defense is stronger! The porous structure in Titanium-nickel foam can absorb energy by deforming when attacked. The shape memory properties of the foam alloy will allow the foam alloy to return to its original shape after deformation.

In other words, armor made with Titanium-Nickel Foam sandwiches has the ability to heal itself.

Wu Chen asked again, "I don't know how your output is?" I have several monitor lizards to arm. ”

"Don't worry, Sag. We have enough resources to help you complete the monitor lizard armament. The chairman smiled and fed Wu Chen a long-term reassuring pill with a shelf life of 20 years.

"Well, thank you." Wu Chen solemnly thanked.

"You're welcome." The directors hurriedly returned the salute.

However, there is no such thing as a free lunch.

As soon as he straightened up, the chairman continued: "Your Excellency, we actually have something to ask you. ”

"What's the matter?" Wu Chen comprehended.

"Have you ever encountered a strange metal monster?" As he spoke, the chairman set his eyes on the dog meat curled up next to the door of the conference room.

Wu Chen suddenly understood: "Is it a gold devouring beast?" ”

The atmosphere also relaxed. It turned out that this was the purpose of calling Wu Chen. Dog meat covered in iron is also widely spread on the airwaves along with the legend of Sag. After being accepted by the academy, this meeting took place.

Everyone present, including Wu Chen, subconsciously breathed a sigh of relief. The directors were glad they had found a clue. And Wu Chen is glad that the origin of dog meat has an excellent cover-up.

"So, Your Excellency met with him?" Signal everyone to be quiet. The chairman asked again.

"That's right, in the Naxigou port area." Wu Chen will tell the details of the confrontation with the Gold Devouring Beast.

"Naxigou Port Area?" After determining that the metal monster that Wu Chen encountered was the target that the academy had been pursuing, the chairman of the board of directors immediately opened the holographic map on the desktop and looked at it carefully.

Then, along the winding Yangtze River. Heading east, the point hits a target point on the north shore.

Wu Chen saw it clearly, it was clearly Chuandong Shipyard.

"Before the end of the day, Chuandong was a shipyard that mainly built oil tankers and chemical tankers. After the apocalypse, because of the lack of information, I don't know if there are still humans alive inside. However. For the first time, we have discovered that the Rust Beast, the chemical vessel of the Gold Eater, is sprayed with paint marks from the Kawato Shipyard. And where you find the Rust Beast, it's a harbor where freighters dock. It is about 100 kilometers from the Kanto shipyard downstream. So, ships, seaports, shipyards. The clues are already connected. ”

"Do you think someone is secretly breeding a gold-eater at the Kanto shipyard?"

"You thought of going with us. That's right, we also think of Goldeaters as artificially bred mutant creatures. The chairman's worries were all on his face: "At present, the Gold Devouring Beasts can only corrode metal, but no one can guarantee that they will continue to mutate and have the ability to devour other elements, or even the entire earth." And from what we've been up to, the Gold Eater has been evolving at a rapid pace. This speed has completely surpassed the laws of nature, just like this apocalyptic change in the last days, which catches us off guard. If we suffer another mutation crisis, it will not only be humanity that will be destroyed. And the whole planet. ”

"So, what can I do?" Only then did Wu Chen realize the seriousness of the problem.

"We would like to ask you to take the time to visit the Chuandong Shipyard as soon as possible to see what is hidden inside." The chairman said the most important sentence of the meeting.

"Yes." Wu Chen had no reason to refuse.

Everyone looked at him differently.

"Yes, Your Excellency. Then please send us the body information of those monitor lizards as soon as possible......"

Before the chairman finished speaking, Wu Chen had already taken out the USB flash drive prepared in advance: "Here is a detailed body structure diagram of the monitor lizard, as well as the design plan of the combat platform, you can use it as a reference." ”

"Yes, Your Excellency." The chairman took it with a smile.

The academy should have more important things to discuss with Wu Chen.

For example, the lizardmen who flood the entire earth.

However. Just like a meal to be eaten one bite at a time, Wu Chen needs to complete the task of exploring the East Sichuan Shipyard and build trust step by step before the academy will discuss the next thing with him. However, Wu Chen determined that the academy was definitely an important thread in this adventure. His invasion of the Fire Dragon Empire. A strong ally is needed. Therefore, the relationship with the college must be well cultivated.

Accompanied by several directors, after a general tour of the base, Wu Chen said goodbye and left, and returned to Daxigou Station.

The advanced host in the RV has completed the integrated design of the biochemical furnace. TT40 is embarking on a retrofit of Wu Chen's suit.

The principle of the modification is actually very simple: a framework built with deformant particles controls the division and proliferation of metal cells to produce a specific three-dimensional structural network. This makes this three-dimensional structure completely encapsulated by a single superbug and gives the superbug space to release high-energy secretions. It then controls the metal cells to devour the 'miniature nuclear bombs' secreted by the superbugs to obtain powerful energy.

Break the superbug into zero. The distribution of the whole body is the focus of the whole transformation.

Wu Chen immediately activated the recovery mode, shrinking the colonization into a small ball composed entirely of mother cells, which was extracted from the navel. According to the requirements of TT40, place this small ball gently on the biochemical furnace. TT40 then activates a powerful 'magnetic flask' capable of binding antimatter, enveloping the biochemical sphere in it.

Change soon began.

Like a rapidly melting ice droplet. The mother cell globules spread rapidly along the biochemical furnace, and soon enveloped the fist-sized biochemical furnace.

Metal cells begin to infiltrate the vascular-like mycelium that surrounds the outer layer of the biochemical furnace. Soon, all the red blood vessel walls were infected. After the mycelium has been segmented at the microscopic level. The rapidly multiplying metal cells began to advance towards the biochemical energy ball in the center.

Cells can engulf bacteria.

For example, the white blood cells in our body. White blood cells are like the "360 security guards" of the human body. When germs invade the body, white blood cells can deform and pass through the capillary walls. It concentrates on the invasion site of the germs, surrounds and engulfs the germs. The battle against bacteria will cause the body temperature to rise, and the manifestation is that we will have a fever. In fact, in a sense, this is also the release of energy.

As metal cells begin to devour the secretions of superbugs. The metal cells that absorbed the 'miniature nuclear bomb' did not convert the energy into temperature and released it in vain, but converted it into life energy. So, she began to divide and reproduce rapidly!

The mother cell divides in large numbers, following the structure of the metamorphic particles. Proliferate rapidly.

The manifestation of this manifestation is that more and more flowing silver liquid with red glow lines meanders from the surface of the biochemical ball, and continues to overflow in all directions, constantly impacting the 'magnetic bottle' that binds her.

"TT40, remove the magnetic flask. They're looking for me. Wu Chen's demigod-level brainwave already felt a familiar call.

"Yes, master." The powerful and invisible electromagnetic field quickly withdrew, and the silver liquid that had lost its restraint flowed down the workbench to the ground, and then converged on the soles of Wu Chen's naked feet. The fluid accumulated more and more on the soles of the feet, and some of the red lines began to climb up the instep of the foot, creeping towards the ankle.

Then he quietly connected the fur on Wu Chen's legs, feeling the warm fluctuations released by the peripheral nerves.

After determining the dominance of the will of the group, countless crimson tentacles began to stretch out of their insteps, flowing upwards rapidly. Some curious babies seemed to want to drill into Wu Chen's body through their pores, and when they felt the sting of the master, they immediately retracted in fright and hid among their companions.

Soon, the metal cell fluid spread all over the body, completely covering Wu Chen. He no longer needs to breathe through his nostrils. Metal cells are constantly injecting oxygen atoms from his pores, merging them into the capillaries and participating in the body's circulatory metabolism.

And those beautiful cloud carvings, like the blood of metal cells, are all over the body. As the colony gets thicker and thicker, it gradually disappears.

During his journey through time with Wu Chen, the metal cells fell asleep because they ran out of energy. Later, due to fire and electric shock, it was partially resuscitated. The so-called partial resuscitation does not mean that a part of the metal cells has been rejuvenated, and a part of them has not recovered, but that only a part of the individual cells have been revived. For example, after being hit by the electromagnetic pulse of the umbrella lizard, the metal cells are restored to 50% vitality, which means that the metal cells that make up the breeding suit have all recovered their vitality at 50%.

However, after devouring the 'miniature nuclear bomb' released by the superbugs, the metal cells quickly returned to 100% vitality and are still growing!

Thus, the metal cell also began to evolve! (To be continued......)
