Standing in front of the mirror-like mountain wall, the first thing Si Mo saw was the row of knives stuck in the big rocks on the mountain wall. The shape of the knife is exactly the same as the green bamboo knife she brought back from the bamboo clan, a row of five large knives, made of bamboo, wood, stone, gold, and jade.

At this glance, she knew that it was used in conjunction with the phantom array that her master had just given her, five opportunities to open it, each time with a knife, thinking of the preparation of her master and sister for herself, Si Mo only felt that her heart made of stone was also warm.

Fifty paces away from the big stone erected by the five knives is a small waterfall, the waterfall is only three stories high, and directly below is a pool of turquoise blue water, and the splashes of the waterfall are constantly raised, creating a psychedelic water mist effect that is not too small or small.

No wonder Master asked her to put the Phantom Array here, with this water, the changes in this Phantom Array are probably even more. Seeing all this did not make Si Mo feel relaxed.

Master and Master have created such good conditions for herself, although there is less than half a month to go, she should be able to cultivate at least two levels of body refining and warding off evil spirits.

Don't think that Si Mo has set too high a goal, a day in the demon world is almost a year in the human world, and even a hundred years in a smaller world, you can imagine how long this day is.

Emperor Xiao didn't know that Mu Shi gave Simo a book of body refining, so what he said before was to let her practice the evil sword spectrum well, which actually meant that she was required to completely master the evil sword spectrum to Dacheng.

Now she just wants to practice the evil sword spectrum to a small level, which is actually not too ambitious.

Body refining sounds simple, but in fact, compared to the small world refining body that Si Mo had before, it was not that simple. She first has to temper her muscles and bones, and the demon clan does not pay attention to the use of medicinal materials, so the so-called tempering of muscles and bones is really "hammering" with external forces.

Luckily, there was a waterfall in her valley, and the water pressure in the water flowing from the height was very high, and although her small waterfall was only three stories high, it was enough for a beginner like her.

"First penetrate the first layer of the refining body, and then go to fight these five swords."

Si Mo thought about it, and finally decided to improve his physical fitness first, sharpen the knife and cut the wood, his body resisted falling and fighting, and the certainty of entering the phantom array to break the formation was still greater.

Under this guiding ideology, Si Mo's cultivation officially began. At first, she was washed down from the slippery boulder by the waterfall again and again, then she gradually stood on her heels, and then she was under the pressure of ten thousand pounds of water, which almost made her vomit blood, and finally she was able to walk freely in the waterfall from head to toe.

Moreover, Si Mo also found that this waterfall also has its own changes with the rise and setting of the demon sun in the sky. For example, in the middle of the night, the water of the waterfall will spread out and all the pressure will drop sharply, but at noon, all the scattered water will be concentrated in one place, and the pressure will naturally multiply.

On the first day, when she was cultivating at noon, she was vomited blood by this sudden change in the huge water pressure pit. It wasn't until the next day that she gradually adapted to the change.

However, since he had discovered this change, Si Mo would formulate his own cultivation plan according to this change. At first, she only cultivated under the waterfall in the evening until the time of clearing the dust, and the water pressure at this time could put pressure on her, but it would not hurt her roots.

And at noon, she used it to rest and ward off evil swords, although the name of this knife spectrum and what can make people feel that pain, but the power is huge, five big knives, she started with the bamboo knife first.

The bamboo knife is light and lifts as if it is nothing, and it does not seem to match the wide opening and closing of the evil sword spectrum. But Si Mo still meticulously pondered the trend and changes of the bamboo knife little by little according to the description on the sword spectrum.

Si Mo believed that his master would not let himself do a useless exercise for no reason. So with this kind of trust, she really figured out the mystery of the bamboo knife on the morning of the third day.
