Two days later, they arrived in the southeastern part of the battlefield.
When Ludwig went outside and looked around, he didn't feel anything special at first, but something inside him told him that this place was a bit weird, it was paler in comparison to the other places in the battlefield.
Naturally the others noticed it too but no one mentioned it, meaning there was no deeper reason for it, at least that was their thought regarding this. Ludwig didn't deign to explain how he felt, he just looked at the paleness and inspected it.
As he moved around a bit while inspecting, he noticed how it got minimally paler. Now, one would think that he shouldn't be able to see, but any landscape that has some spirituality is represented in the ethereal world, and the colour-change was only perceptible for him because he was constantly using his ethereal perception.
The blood-red colour must have had a unique origin, for Ludwig was able to see this colour fully even in the ethereal world. As they moved, he inspected the colour more and more and made the carriage move towards where it was paler.
At one point, he realised something and halted. 'I should be in the inner ring, if we go any further, with the range of the formations we'll put in place, they might realise it... it's better to halt here.'
He looked around and saw that this was already a good place, they were moving about for a few hours, so by now everyone was just waiting for him to say whether he was satisfied, the others couldn't be bothered anymore, it all looked the same.
Naturally some perceptible people saw the colour change in a small scale but didn't care about it. Ludwig came from a somewhat high society where even small change in geography could mean something deep, so he paid more attention to that. This wasn't a difference of technological progress, this was a different of cultures.
The further you went up the ladder of cultivation, the less you thought like a mortal. Ludwig lived the mortal life from beginning to end, a whole mortal life, this is more than the very most cultivators ever did, so he had an advantage in this regard, but he also still has some values and culture of mortals.
His values were different since he was a serial killer, but he still had the culture of mortals and the innate fear that even small change could kill numerous people. With his stay in this world, this innate fear gradually receded, but he still kept the inadvertent attentiveness of his surroundings.
He stopped paying attention to this and used his ethereal perception to look all around his surroundings. It seemed that this inner ring is also the cleanest in regards to pollution of spiritual power, the pollution was minimal in the first place, now in this place, it seemed even a body strengthening cultivator's body could filter it easily without being affected.
He looked around a bit more and found a small gathering of spiritual power, so he moved there, and felt how the pollution was nearly fully gone. When he felt a bit more and saw that this was probably one of the best places in the southeastern region regarding pollution, he was satisfied and looked back at the people standing with no expression.
"We will settle down here. Wei, come here and inspect the earth roots and tell me whether they are suitable for enhancement as well as for formations. Ye, you should inspect the movement of the sun here and write some charts of the sun and the stars."
Understanding that the sun is a star is not a difficult task, so naturally cultivators know it. Unfortunately it can be said that the power of the sun is unproportionally strong, making it difficult to integrate it into a formation together with the weaker stars.
Nonetheless, at least it was good to have the path marked down, so they'd be able to use the sun shine as an guiding force to ensure that the formation is always connected to the stars and isn't weakened during the day.
As for Wei, in the past three months of preparation, he was told that she is actually a formation master just like Ye. It was funny how well they fit together, but there was one difference, which is that she is a master of terraforming, meaning the formations she creates often use the natural given earth veins and transforms them wholly into what she wants them to be like.
For normal formation masters, earth veins are unmovable objects whom you would have to follow to the bit, but she is very talented in this regard and can move them. With enough time, it is estimated she could even build a huge paradise out of this battlefield. There are certain formations for moving earth vein, but what she relies on are formations that use the earth and spiritual power to grow an earth vein from the beginning.
For Ludwig, he knew this is a much better formation than moving earth veins. The places where they are moved from will suffer, but earth veins that are created anew? One couldn't even say that they are formed artificially, no, that is also a way, but the way of Wei is to be an earth mother.
This path is particularly liked by Heaven and Earth, which is why her cultivation is smoother, even though she has two spirit roots, her speed is the same as one with a strange spiritual root.
Naturally this is also the limit to heavens help. It's actually quite surprising, since Ludwig was told that Wei's earth root is actually the minor root and her water root is the major one, but for some reason, her parents insisted on testing whether she was able to follow along this path since she was tested and was acknowledged to be talented in terraforming.
