"The second mountain is at least twice as far away as the one just now, and if those ghosts still appear, we have to find a way, otherwise it will be difficult to deal with. And although it is not clear to see, the third and last mountain is probably more difficult to reach. ”

"Hmm." The main body nodded, and the enemy's most annoying thing was that it couldn't attack.

In this way, if you let the opponent chase after you, you are really passive, either you will kill the opponent, or you will have to speed up the speed of breaking the formation.

"Every pillar we broke just now is a complex composite formation, which has never been seen before." One of Yu Zhi's clones thought of this stubble, but as soon as the words came out, the others were stunned.

Yes, every time a pillar was broken just now, it was like remembering a big array.

I didn't feel it when I cracked it, but now I realized the preciousness in it, so far, Lu Chen's inspiration flashed, he didn't hesitate, he immediately started, and each person remembered one formation at a time.

"There it is!" A Yu Zhi clone took the lead in completing the memories, and delved into it, and soon integrated and learned this formation.

The ontology and other clones have different memories and research speeds depending on the formation, but they will not differ much.

Gradually, Lu Chen ate all the formations he encountered along the way.

It took weeks.

"Huh?" He stepped out and gazed at the sea outside the cave again, and found that he looked at the pillar in front of him as if he had seen a delicious delicacies.

"Huh......" Lu Chen gasped slightly, he suddenly didn't want to rush through the barrier, looking outside, there were still countless pillars here, like the ocean, which could not be studied thoroughly.

Lu Chen walked down the hill with the clones, everyone held together, and once again studied the formation in the same way as before.

Until it went deep into the depths of the Pillar Sea, the mist came again, and this time the image of the ghost was still himself, and the evil aura continued to cleanse.

The ghosts, though slow, were unhindered.

"Go back." Lu Chen snorted and walked towards the mountain again according to the original way and using the previous method of dissolving the formation.

This time he was much more conservative, he didn't go too deep, and he was relatively comfortable, and soon Lu Chen returned to the cave on the hill.

Only faintly, he seemed to feel that he had changed, and it seemed that the speed of dissolving the formation had increased slightly.

Although it was not obvious, Lu Chen just felt that his calculations and memories were smooth.

Sitting in the cave, he repeated his old tricks, using the previous method, each doppelganger calculated and familiarized himself, and studied the formation just now.

This time, in order to avoid danger, he wrote down a little less formation, and he completed the familiarization of all the formations in a tight week, which made his thoughts more and more transparent.

So, Lu Chen simply didn't get up in a hurry, but repeated the old trick and continued to use the same method to learn the rune formation here.

Anyway, there is no time limit for breaking into the battle, as long as you can live, it doesn't matter how long you are here.

He stopped there and didn't go any further. Because after several experiments, Lu Chen found that by learning the formations here, his memory and calculation ability had improved.

It's not fast, but what I have is time.

At least learn more formations that can be learned, so that the formation can be broken faster, otherwise it will be a dead end.

To be able to endure such a boring study, you need to have a strong interest in the rune formation, otherwise you would have gone crazy a long time ago.

Now, as research and learning continues, Lu Chen's mind is becoming clearer and clearer.

What I learned before, as well as the basic knowledge I learned in the mechanical family, is now completely integrated with the powerful "Sea of Questions"!

Three whole years.

"Hahaha!" Lu Chen galloped in this sea of formations, his eyes shot a confident light, he was almost familiar with most of the formations here, and his formation breaking speed had greatly improved compared to the beginning.

Again cast to the wisdom clone, their mental memory is also improved at the same time, several people work together, and the speed of breaking the formation is even faster and faster, this kind of improvement is impossible for one person to achieve.

Faced with such a treasure trove of knowledge, Lu Chen simply traveled through all the formations in this place before he gave up.

Half a month later, Lu Chen sat on the top of the mountain, looking at the sea of formations behind, the number of formations there was even more exaggerated, and even increased geometrically, he wanted to study the formations here, and use the cave to shelter himself.

However, just as Lu Chen stepped into the sea behind the mountain, the cave where he had lived for several years suddenly heard an explosion!

The totem pole at the entrance of the cave exploded and shattered......

"What ——?" Lu Chen was secretly shocked, it seemed that this Ten Thousand Formations Sea was not defenseless, and it was not unrestricted for the skillful method of studying the continuous improvement of the formation.

He didn't hesitate to speed up with the other clones! There is bound to be danger here.

It is very likely that the ghosts like that in front will appear again, and it is unknown how many there are, and Lu Chen suddenly found that the time for the pillar in front of him to disappear and change was shortened to forty-five seconds.

Don't look at the difference of only fifteen seconds, but the more you improve, the more difficult it will be, which has also reached Lu Chen's limit.

He quickly broke through the formation and advanced until he went deep into the sea of formations, and the rear again "Ding!" With a bang, the ghost fog suddenly rose.

This time, Lu Chen's own figure reappeared, his appearance did not change, but he changed his clothes, dressed in a white robe, and came with steps.

That strange appearance, ordinary creatures have long been affected and paralyzed in fear, but unfortunately, Lu Chen has real demon blood flowing from his body.

He is a natural enemy of a terrible ghost, and he is not afraid.

Lu Chen's speed was fast, heading towards the second peak, the cold air on his face swirled around, and the formation continued to change.

At the beginning, although the chasing soldiers were reluctant, Lu Chen was able to cope with it.

But gradually, he found that not only did the speed of the formation move become forty-five seconds, but also the difficulty and complexity increased.

This situation made Lu Chen a little unbearable, and he didn't even crack the pillar correctly several times.

"Huhu ......" looked at the fierce ghost who was chasing after him, his breath was short, and his eyes flashed cold. He is the last Yuzhi clone in Mangyun Star, and he has been studying the formation all year round, and he is by his parents' side.

The most important thing is that the existence of this doppelganger can keep track of the situation of the Huaxia people at any time. From time to time, he was even able to team up with Dai Mingzhang and others to help them obtain resources.

If this last clone disperses, his connection with Mangyun Star will be temporarily cut off, and it is uncertain when the formation in front of him will be broken.

It will be difficult to estimate how long it will take to return to Mangyun Star.

......Although this decision is very difficult, no matter what, it can't be delayed any longer, otherwise his life will be lost.

Fortunately, he had already greeted his family and Mang Yunxing in advance, so he was not caught off guard and didn't know what was going on.
