Starting as a Wallfacer, his defection to the Three-Body Problem shocked the world.

Crisis Era Year 20.

It has been about 17 years since Lin Xuan became a Wallfacer.

With Reach as an anchor point, humanity has deployed a complete defense system in geosynchronous orbit, and infrastructure development is also continuously progressing.

The number of space elevators increased from the initial three to twelve, making space travel increasingly cheaper.

Some commercial companies have even taken their trade to space.

In this era, a concept called "space burial" has emerged, which involves sending one's ashes into space after death for an interstellar journey.

Quite a few people are willing to pay the price for this behavior, after all, none of them want to live on an Earth occupied by the Trisolarans.

Although the progress of the Mirror Project has been increasing, building an underground city is not something that can be accomplished overnight. There are many problems that need to be solved. In fact, at this stage of construction, they have encountered more technical difficulties than when building Reach.

The only one who consistently produces scientific research output is Principal Liu Chang.

Over the past few years, he has successively solved the problems of enhancing the immune system, synthetic meat, and preliminary experimental results of autonomous evolution.

The synthetic meat produced by the University of Chinese Academy of Sciences (UCAS) is actually not very tasty. Some students from the main campus complained that it was almost as bad as the food in their school cafeteria, truly giving them a taste of what it means to be "tasteless".

However, it is relatively nutritious and can be used to fill an empty stomach, so these synthetic meats are often used together with rice ears from previous studies for disaster relief.

But this doesn't actually solve the fundamental problem, since what's causing people to go hungry isn't natural disasters, but man-made ones.

The really good news comes from Wang Miao.

After completing the basic construction of Reach, he returned to Earth to assist Lin Xuan in advancing the Super Dream Project.

The basic attempts at synchronous verification have proven the feasibility of this approach; the next step is to begin applying synchronous verification to experimental applications.

Wang Miao borrowed a group of experts in materials engineering from Liu Chang, and then had them connect their thoughts and consciousness using the Super Dream World to begin the experiment.

Just like what Lin Xuan saw at Beijing University of Aeronautics and Astronautics, they first conceived a proposition, then built a perfect physical environment in the Super Dream World, made the model and experiment first, then brought it into the real simulated physical environment to verify the results, and finally output the successful results and reproduced them in reality.

"The first experiment reveals the direction for upgrading nanomaterials."

Wang Miao put forward a proposition.

He still has no intention of giving up on the research of nanomaterials, and he always feels that this technology should be able to make another breakthrough.

Soon, the first experimental group produced its conclusions.

"400 people participated in the experiment. 53 people proposed solutions for plasticity, 121 people proposed solutions for increasing strength, and 226 people proposed solutions for adding redundant properties to achieve composite materials."

After a moment's thought, Wang Miao selected plasticity and composite materials as the reference group.

He can freely switch the detailed progress of a particular experimental group he wants to observe, while more than 8000 other experimental groups will continue to provide better solutions.

"The plasticity group chose the plasticity solution, 18 people chose to add AI assistance, and 35 people chose to reorganize the particle structure."

"Begin verifying the results and send the conclusions from both sides back to the entire experimental group for evaluation."

"The AI-assisted technology was eliminated with 5312 votes, and the result was resubmitted for a second evaluation."

"Second round of evaluation complete. 7600 votes for elimination. AI team, please select whether to conduct a third round of evaluation after modifications?"

"AI group rejects, automatic abandonment."

"The AI-assisted group was deemed a failure, and the database retains this opinion."

Wang Miao let out a long sigh.

If the Sophons hadn't blocked fundamental physics, the nanomaterials created with AI assistance would definitely be the right path. But unfortunately, the Sophons are blocking their way, giving them no chance at all.

"Next, we will verify the recombined particles and establish an ideal physical model..."

"Establishment failed. An unknown error occurred with the quark unit. Analysis is underway. Should the experimental group conduct a third analysis?"

"The experimental group is conducting an analysis and integrating data. They have detected a proposed modification to the composition of nanomaterials within a sub-branch of the composite group. Should we attempt to integrate this with theoretical findings?"

"Integration successful! Ideal physical environment model successfully established! Simulated physical environment successfully established!"

Ultimately, Wang Miao obtained a composite material of nanomaterials.

Nanomaterials 2.0 was born!

This material is an upgrade of his designed nanomaterials, which not only increases its strength but also reduces its required mass, making it much lighter.

If the previous three space elevators had been designed using this material, there would probably be no need to worry about the counterweights at all.

Most importantly, this material also has a very strong plasticity, which will make it quite useful in the future, whether it is used to make weapons or simply for defense.

Lin Xuan was very pleased to learn of the result. He immediately instructed Wei Cheng, who was building the mirror project, to replace the steel supporting the city at the bottom with this new type of nanomaterial.

As a result, the speed of the entire mirror project, which had already slowed down, suddenly accelerated again.

This only solved one small problem; another problem that had been bothering Lin Xuan for several years was also about to be resolved.

"Prepare to wake up Hines. The analytical camera he wants is about to be built."

Lin Xuan submitted a project application to PDC and began developing the analytical camera that Hines needed for his project.

The reason they didn't build this thing back then was simply because their materials were too outdated, unless they used the Mewtwo database to complete the analysis process.

But that would consume an enormous amount of brainpower.

With the current fourth generation of Thinkers array, it would take more than two thousand clones to complete the task.

It wasn't that Lin Xuan couldn't produce that many clones; he just didn't want to reveal the fact that he had been researching cloning right now.

Therefore, the simplest solution is to find a way to replicate the supercomputer from the original storyline in order to complete the brain analysis process.

Actually, Lin Xuan had another thing she was hesitant about, which was whether or not she should break through the barrier to help Hines.

The existence of the thought imprint has a significant impact on the future development of the plot, and we must wait until the imprinted race develops.

Therefore, he must have a very good grasp of the timing of Hines' breakthrough; if it is too fast or too slow, it will affect his subsequent series of plans.
