Lin Feng stood on a silver-white metal building and looked at the mechanical zerg base that had begun to take shape.

At this time, the silver-white matter in the sky gradually increased from far to near, and then began to solidify and fill the mechanical zerg base that had not yet taken shape when it reached Lin Feng's feet.

"The principle of this nanoworm forming a mechanical worm can also be extended, and it is best to develop into an immortal civilization, and all creations can be directly constructed with nanorobotic worms. However, this should be difficult, and there are many problems to overcome.

The first problem to be solved is how to nanoscale those rare and special resource minerals, and even develop nanorobotic insects made of these special and rare resource minerals, so that we may be able to consider the future development direction of the immortal civilization.

If the expansion of the application of nano-robotic insects can be successful, it can take into account both of them, just like the mechanical zerg, which can be freely converted in the nano-state and the insect-like state. ”

The quantum computer in Lin Feng's brain at this time was running rapidly, for the immortal civilization, there is still a certain gap from the second-level scientific and technological civilization, the last time Lin Feng observed his civilization index, the civilization index only reached about 68, and there is still a way to go to reach the peak civilization index of the first-level scientific and technological side civilization of 100.

However, Lin Feng already felt that it was time to think about the future development direction of the Immortal Civilization.

The Immortal Civilization is a mechanical intelligence civilization that belongs to the scientific and technological side, which restricts the development of the Immortal Civilization in the conventional direction of purification, and it is speculated that the Guardian Civilization of the Holy Land, the first advanced civilization that Lin Feng encountered, should be a civilization that develops towards purification.

"I didn't expect that the problem that had plagued me for so long about the future direction of civilization development would be easily solved in this way." Lin Feng read the results deduced by the quantum computer and smiled with emotion.

Originally, nanoworms were developed only to be able to carry mechanized viruses, which means that the appearance of nanoworms was completely an accident or nanoworms were just a by-product, and then it was the mechanical zerg formed by nanobugs that was developed under the importance of nanoworm technology, which is a special war unit.

Now, under Lin Feng's deduction, it is found that nanoworm technology is promising, and it can be used as the direction of choice for the future development of immortal civilization.

"After reasoning and analyzing in all aspects, the development direction of nanorobotic insects is now the most suitable for the immortal civilization. Store first, set as the first reference target. Lin Feng stored the results of the various analyses after the deduction and transmitted them to the civilization database of the mechanical source realm for future reference.

"The situation on the planet today is really complicated." After storing the deduction data, Lin Feng checked the information on the current state of the earth collected by the scouts.

"That is, the earth happens to be a world of civilization player selection, so there are many civilization players in order to survive the invasion of the abyss, if it is like Blue Star, it has been destroyed I don't know how many times. And these abyssal creatures aren't as merciful as I am. After reading the information, Lin Feng analyzed.

"However, the Tombstone and the Zerg Master don't look like the kind of people who want to destroy their own world, but why is the door of time and space that they opened now being fixed? And what exactly is the world promotion that Drifting is talking about, is it like the promotion of civilization level? And the devouring war between the two world tree systems, is it like the situation that happened after the collision in the legend of the Star Sea Universe? ”

"I always feel that something terrible is about to happen, and I have a hunch that in this turmoil, my immortal civilization should be able to be promoted to a second-level civilization."

"Huh! Is this the portal of time and space that the tombstone began to connect the abyss? Lin Feng saw a picture mixed in with the intelligence.

"What is this? Magnify. Lin Feng, who was carefully observing the picture, saw that there were some special objects next to the gate of time and space.

"Skeleton fragments, I thought it was!"

After zooming in on the picture, Lin Feng saw that this particular object was just a bone fragment of a skeleton.

"No, this is..."Lin Feng originally thought that this skeleton bone was a normal dry bone, but when Lin Feng looked at it carefully again, he found that it was different, this skeleton bone seemed to emit a faint fluorescence to the outside world, and some tiny handwriting faintly appeared.

"Scout, bring this bone back, and look around for any identical skeletons." Lin Feng ordered one of the scouts in charge of the investigation of the situation near the Gate of Time and Space and ordered her to bring the bones back.

...

"Just four skull bones." When the scout brought the bones back according to Lin Feng's instructions, Lin Feng looked at the four bones in front of him and thought.

"There should be, but maybe on the abyssal side." After Lin Feng spliced the six bones together, he looked at the defects and muttered to himself.

“... I hope that the message I send back will show that maybe I am already called the sinner of the earth, but I don't want to do that either, when I and my two companions....

The Abyssal World is a place full of unknown horrors, with... Sent by an unknown and terrifying being... A companion is banished to the endless void by an abyssal monster, and there is a... The gate of time and space that I opened was completely solidified by the existence of unknown horrors, and it was a premeditated... This will be just the beginning, a rehearsal of a catastrophe that will affect the entire endless world. ”

After Lin Feng intermittently read the information engraved on the skeleton bones, he lowered his head and pondered.

Lin Feng was easily able to analyze that this was the information left by the tombstone, but because the information was incomplete, Lin Feng couldn't learn more about it, and he didn't know whether the tombstone and the Zerg master were dead or alive now.

"Whew!" Lin Feng let out a breath slowly, still thinking about the meaning he wanted to express in the message left by the tombstone.

"The fear of the unknown exists, the forced solidification of the gate of time and space, the premeditation, the rehearsal of the catastrophe. What the hell is going on seems to be more complicated and frightening than I guessed. Lin Feng, who frowned, relied on the only information he had to try to get a trace of the truth, but unfortunately there was too little information.

"The most important thing is why the tombstone says that this is a disaster that affects the entire endless world, even if the gate of time and space is solidified, and the earth merges with that abyss, it is just a disaster that affects the two world tree systems, and it is still unclear whether it is a disaster or chance?"

"Ahh It's annoying, forget it, the boat will naturally go straight to the bridge, if it is really a catastrophe that affects the endless world, there are also those top existences or civilizations to carry, my immortal civilization is just a small shrimp that has not yet reached the second level of civilization. ”

"Scout, see if there's a chance to go to the other side of the space-time portal and collect these bones with this information." However, although Lin Feng said that he was tall and resistant, he was actually very concerned in his heart, because it was never better to rely on others than to rely on himself.
