The most scarce water resource problem in the fragmented city was effectively solved after Xu Ran sent in the water droplet storage device of the one million tons of water collected to replenish it.

With water resources, the pace of development in fragmented cities has once again accelerated.

Not only has the power generation efficiency of the underground power plant been improved, but the facilities of the underground city have also resumed operation after sufficient power resources are available.

The most important thing is that after some industrial production equipment in the underground factory is put into operation, it can be guaranteed by the abundant resources in the fragmented city, and can produce all kinds of required super materials and equipment in large quantities.

At the same time, the start of production of the robot factory, when the industrial robots are produced and put into work immediately under the overall planning of An'an, the productivity and production efficiency of the fragmented city have been greatly improved.

With abundant water resources, everything is starting to develop on a virtuous track.

Xu Ran went to the purple light laboratory to learn about the latest progress in purple light research, but gave Xu Ran a surprise.

In the process of experimenting with purple light, An Shou found that the energy of purple light can be stored after reaching a mild state through the attenuation of the violet light.

Since this energy can be stored, the characteristics of violet energy can be used to study and manufacture super violet cells, which are currently in the laboratory and have been put into the experimental stage.

In addition, the quantum creatures that Xu Ran brought back to the Fragment City and the energy pool of the convergence effect also played a very huge role.

An An has conducted some experiments using the energy pool of the polymerization effect to build a reactor, and can use the properties of quantum space to transform matter when promoting the maintenance of the energy balance state of quantum organisms.

Just like the robot that Xu Ran brought back last time, it was because of this special situation that a quantum reorganization occurred and it became a mini robot the size of a broad bean.

Then, through the research of nanorobot technology, combined with the characteristics of this quantum recombination, An An has vaguely made a breakthrough in the existing robot technology in the Blue Star World, providing a new idea for the research of quantum robots.

After staying in the two laboratories for a long time, Xu Ran experienced another purple light from the Fragmented City.

For the process of the arrival of the purple light this time, Xu Ran was looking forward to it.

Near the command center on the ground of the Fragmented City, a purple light energy attenuation control array has been set up there, and the whole looks like a rotating silver spinning top.

When the purple light comes, the purple light will cause reflection and rebound effects after shining on the rhodium light plate, and the rebounded violent purple light energy will go through a decay, and then enter several reflections and rebounds through the lower layer, and finally attenuate the violent energy to the mildest state.

At the bottom level, there is a violet energy reaction cell, and after being attenuated, the mild violet energy will be channeled to the equipment there for storage, which is similar to the situation of collecting solar energy.

Of course, Xu Ran has been in the Fragment City for so long this time, in addition to participating in the scientific research project of the laboratory, he also has a purpose, that is, through the collection of purple light energy, he wants An An to temporarily help him create a purple light shield.

That's right, it's the purple light shield, Xu Ran's purpose in asking for this thing is to enter the tomb temple in advance before the expedition team organized by Huo Sifar enters the ancient tomb, and get his hands on the moon-shaped, huge star core meteorite.

Now that the star core meteorite has been discovered by the earth science community and is paying more and more attention, as long as each stone is found, it can be sold for a sky-high price, so it will be more and more difficult for Xu Ran to collect.

Since this is the case, it is better for him to go in again in advance and get the star core meteorite in order to feel at ease.

It's just that the mutant creatures in the temple are highly poisonous, and there is a tentacle monster in the pool in the square, which is very dangerous, just in case, and the time is urgent, then Xu Ran must ensure that he can have a very good protection measure.

An An spent about six hours for this demand put forward by his boss Xu Ran, but he succeeded in creating a purple light shield with a very simple function and relatively rudimentary functions.

When Xu Ran got the purple light shield, he still felt full of technology, and it was like a sword in his hand, a bit like the Force lightsaber in the Star Wars movies.

But in reality, it is not a sword, but a button in the middle that activates energy, and as long as you press it, it will activate the purple light energy, and then release a shield.

The shield was a bit like a light mask, but in fact, it was an energy network formed by purple light energy, in an arc shape, which could well protect Xu Ran from dangerous creatures inside.

After all, it is a temporary shield, and there are only two simple functions of sending and receiving, that is, activating, turning on and off the shield, and there are no other applications.

But with such a feature, it is already possible.

After getting the purple light shield, Xu Ran didn't waste any more time.

After selecting two robots to follow from the robot team that followed him to explore last time, Xu Ran came to the teleportation point and used the space key to open the teleportation.

The destination of this teleportation location is the force field guidance that can be used for natural fixed-point teleportation hidden in the ancient tomb of Shahaigouzi.

In fact, it was the mysterious altar that Xu Ran hadn't explored last time, and it was Xia Tanhe who was able to escape.

Xu Ran suspected that it was the True Ding Altar that Huo Si Faer had been looking for.

In this teleportation, Xu Ran did not set the coordinates at the coordinate position where he entered for the first time, but shifted a little towards the position of the temple's side pavilion.

Because he had entered it once, he already knew the situation around the temple, and he didn't have to start again from the secret passage of the ancient tomb when he went in again this time.

Of course, the most important thing is the huge star core meteorite, which is a naturally existing guiding force field, Xu Ran uses the teleportation point here to teleport, and he can get there directly, after all, last time he asked the robot to drag the star core meteorite out and put it in an open place, just to enter it for the second time.

And after entering this time, after getting the star core meteorite, you will have to open the fixed-point teleportation, which requires the use of the mysterious altar that Xu Ran has not explored before.

After making a plan, Xu Ran did not hesitate, brought two robots, and after making all preparations, Xu Ran used the space key to teleport.

And the next moment, just in the blink of an eye, Xu Ran raised his eyes again, and found that he was already in the middle of that temple.
