After a short period of warmth, the two of them began to get busy again as the refining furnace stopped running. Fuel cells can last up to 12 hours, so make the most of this time.

With the refining furnace, the supply speed of various materials has increased greatly, and Chu Jungui began to think about how to solve the energy supply problem that has become a bottleneck.

Usually the most common practice is to use biomass or chemical energy to generate electricity, such as building a diesel generator or something. But on Planet Four, Chu Jungui has not yet found a similar energy source.

There are plants and wood, but these trees only look like wood, but they are not combustible. And the oxygen content on this planet is pitifully low, and there is no way to burn it in the conventional sense.

However, without oxygen, it can be replaced by other oxidizing agents, such as chlorine. Planet IV has exceptionally high levels of chlorine, and analysis of known alien organs suggests that they rely on chlorine as an oxidizing agent to fuel their bodies.

If living things depend on chlorine, how do plants get their energy?

Chu Jungui looked at the huge arc-shaped leaves of the distant forest, thoughtful, and faintly felt as if he had caught something.

The test subject was lucky, and at this moment, an extremely violent ion storm suddenly surged in the sky, and a pillar of thunder as thick as a stone pillar fell from the sky, with thousands of thunder balls attached to it.

The thunder pillars went straight down, slashing directly into the forest, and the thunderballs also fell one after another, smashing into the forest one by one.

If it was on the human home planet, it would definitely cause a forest fire, but on Planet 4, a miraculous scene appeared in front of Chu Jungui.

The entire forest sucked the thunder pillars into it like a sponge, and each tree glowed slightly. The same is true of those thunderballs, all absorbed by the tips of the leaves that are straight up to the sky. Then the whole forest glowed with a hazy light, like a fantasy world.

Lin Xi also saw this scene, and in shock, she suddenly said, "Look at those leaves, do they look like receiving antennas?"

Chu Jungui was reminded by her, a little abruptly, and said, "You mean ......?"

"The whole forest is connected by all the trees underground, which means that the forest is like a huge battery that can absorb the thunder and lightning energy that overflows from the sky. In normal times, these trees live by absorbing radiation and electromagnetic waves from the ion storm layer. ”

As he spoke, Lin Xi kicked the purple grass and said, "It's not just the trees, maybe these grasses are the same." ”

Chu Jungui lowered his head and pulled up a small grass and looked at it carefully. The grass has purple leaves that open at the tip and look like petals. But from another point of view, it can be said that it is an open receiving antenna.

The grass has a tuber the size of a finger, which looks very fat, and its roots are extraordinarily long, and even if they are broken when pulled out, there are tens of centimeters left. And on the remaining roots, there are obvious roots that belong to other small grasses entangled. This also shows that the meadows are also connected underground.

Looking at the grass under his feet and the forest in the distance, thinking that these seemingly independent individuals were actually connected underground, for some reason, Chu Jungui felt very uncomfortable inexplicably.

As soon as Chu Jun pondered, he built two more wooden tables and doubled the work area outside the cockpit. Then he built an organic matter detector side by side with the original one, so that the power line could be shorter.

With two organic matter detectors, the speed of analysis can be doubled. Chu Jungui discovered that the creatures on this planet themselves hide many secrets, and uncovering these secrets may be the key to survival on this planet. Just as analyzing the blood and muscles of the alien beast gave Chu Jungui a stable supply of bullets and building materials for fortifications.

The organic matter detector was well built, and a new detector was up and running in a few moments. This time, Chu Jungui put in the trunk of the double-leaf tree that he had been ignoring.

Surprisingly, the analysis of the trunk material was extremely slow, and it took more than three hours. Chu Jungui had no choice but to wait patiently.

At this time, another analysis of the internal organs of the alien beast came to fruition. This was a fist-sized globular gland in the body of the alien beast, and it was only because it grew near the brain that Chu Jungui noticed it and tested it.

After Chu Jungui entered the test report into the chip, he obtained the potential processing direction and use of the contents of this gland, the most important of which is: to replace the contents of the polymeric battery.

Polymer batteries were the most common inexpensive batteries in the 35th century, and their popularity was similar to that of lithium batteries in the era of the home planet. Most importantly, it can provide a vital transition before Chu Jungui can find stable long-term energy.

Chu Jungui immediately stopped other work on the chip and made every effort to design a new polymer battery based on it. This task was not difficult, and the chip only took 15 seconds to give a design solution. This is actually because the glandular fluid itself is a near-perfect battery material, so more time is spent on designing the battery shell to make the chip.

The design of the polymer battery shell is also a science, which should be easy to stack, can be seamlessly interconnected, and should be generous and beautiful, preferably with a special design of postmodernism......

Chu Jungui interrupted the increasing aesthetic demand for chips, chose the simplest shell that could be stacked directly together, and then formed a design plan and entered it into the workbench.

In the process of producing the first polymerization battery, Chu Jungui told Lin Xi about the new plan, and the two of them worked together to move all the corpses of the nearby beasts, and then dissect the glands.

Because the function of this gland is to generate electric current, thereby powering the alien beast, Lin Xi named it the thunder gland.

In addition to exotic beasts, lizardmons and spinybacks also have thunder glands of varying sizes.

The thunder glands on these beasts are generally not large, and about ten thunder glands are enough to produce a polymeric battery. Although Lin Xi was a little disappointed, it was better to have dozens of batteries than nothing.

When the first polymeric battery was produced, Chu Jungui cleared an open space outside the cockpit and connected it to the cockpit's overall power supply network. After the battery is connected, the personal terminal updates the power supply data as soon as possible, and the final data shows that the battery output power is 20kw and the continuous energy supply time is 48 hours.

Chu Jungui was overjoyed in his heart, this data far exceeded his expectations, it seems that the use of electricity by the creatures on Planet 4 has reached a very high level, but it is cheaper for Chu Jungui.

Although the fluid of a single thunder gland is limited, the number of alien beasts seems to be endless, and at least the two of them have enough stock on hand to make 30 fusion batteries.

Once the energy bottleneck is broken, the future of Chu Jungui and Lin Xi will have the first glimmer.
