The water column sprayed for a maximum of ten breaths before falling into the lake again. The entire lake has also become the same as before. If it wasn't for the ripples still rippling on the lake, Ning Cheng might have thought that he had read it wrong.

At the same time, Ning Cheng could clearly feel that the sprayed water column had a strong spiritual energy, which was much more abundant than the surrounding spiritual energy.

After Ning Cheng knew that this might be Daan Forest, he didn't dare to be reckless. No matter what was at the bottom of the lake, it wasn't something he could move with his current cultivation. If his cultivation was higher, he might go to the bottom of the lake to see the situation, but now he doesn't want to move here.

Backing away from the lake, Ning Cheng found a giant tree with a diameter of nearly fifteen meters. He planned to temporarily cultivate at the heart of this giant tree. Trees with a diameter of more than ten meters are not many on earth, but they are everywhere here. The tree that Ning Cheng found wasn't even the thickest, just because he hid in this tree to cultivate, he could directly see the movement in the lake.

Ning Cheng thought he was going to make a tree nest for himself, but after he got to the top of the tree, he realized that there was a huge cave in the heart of the tree. There is a fishy smell in the cave, and I don't know which kind of monster left it. Judging from the inside of the tree hole, there should be no monsters entering the tree hole for many years.

Ning Cheng cleaned the tree hole, and placed a concealment formation and a defensive formation above the top of the tree. He didn't dare to arrange the formation by the lake. His formation level was too poor. Although he could barely understand the second-level formation, with his level of refining the formation flag, he could only arrange some first-level formations at most.

Sitting in the tree hole, Ning Cheng set up another first-level formation to hide his breath, and then he felt relieved. The arrangement of some array methods made Ning Cheng understand that no matter where he was, the more he knew, the better it would be for him. If he doesn't know how to form, he can only be the same as before, and he can only passively pray that others don't find it here.

Now that he has arranged a formation, even if there are monsters attacking him, he will know before that.

Although he was sitting in the tree hole, all the changes in the lake were in Ning Cheng's eyes.

More than 200 spirit stones were taken out by Ning Cheng, and he planned to raise his cultivation to the late stage of Qi Gathering.

With Ning Cheng's cultivation, he once again forgot everything, and he turned the spiritual stones into powder, and the spiritual energy in the spiritual stones combined with the mysterious yellow aura constantly washed his body. Ning Cheng could even vaguely feel that while his cultivation was improving, his spiritual aptitude was also improving.

Even if there is a spiritual energy to replenish, Ning Cheng still needs to eat something from time to time. He has not yet been able to cultivate to the point where he can rely on spiritual energy alone.

Day by day, when the zhenqi in his body gathered to a certain level again, a small light sounded in his body, and then the powerful zhenqi rushed through the meridians of the whole body. Some impurities in his body were expelled from his skin, and the powerful True Qi transferred Ning Cheng to know that he had advanced to the fifth level of Qi Gathering.

Ning Cheng heaved a sigh of relief and opened his eyes to find that all the spirit stones he took out had been used up.

"It's amazing." Ning Cheng muttered to himself, from the fourth level of Qi Gathering to the fifth level of Qi Gathering, he used more than 200 spirit stones.

Not only that, it took him a month to advance from the fourth level of Qi Gathering to the fifth level of Qi Gathering. If it goes on like this, the remaining spirit stones will definitely not be able to support him to cultivate to the seventh level of Qi Gathering.

Ning Cheng took out the two spell jade slips that Fang Yijian had given him. He advanced from the fourth level of Qi Gathering to the fifth level of Qi Gathering, and his spiritual sense more than doubled again, so he should be able to see the contents of the jade slips. He doesn't have many spiritual stones, so he might as well study spells.

This time, Ning Cheng's spiritual sense did not disappoint him. His spiritual sense swept the first spell on the jade slip, and he could clearly see the content of the jade slip, Xuanbing thirty-six shots.

After he understood the contents of the jade slip, Ning Cheng was about to scold him. Fang Yijian, the bastard, knew that he only had a flying sword, but he gave him a spear trick. Although it is a Xuan-level exercise, what use is it to him? He didn't even think about gun-like magic weapons, not to mention that this shooting was not suitable for his spiritual roots.

It is difficult to have advanced spells, but cannot practice. Although Ning Cheng was very depressed, he still took a look at the thirty-six Xuan Bing guns.

It's fine if he doesn't look, but the more he looks, the more depressed he becomes. After cultivating the thirty-six spears of Xuanbing to the end, thirty-six spear beams of Xuanbing can be formed. These thirty-six beams of spears can form a network of spears, or a formation of spears. Under the shroud of these thirty-six guns, where is the opportunity for ordinary opponents to escape? This is a big killer.

Things are good, but he can't cultivate, Ning Cheng sighed and threw the jade slip aside, and took out another spell jade slip again. The words on this spell jade slip made Ning Cheng even more angry, the Seven Luminaries Ice Needle. This is also a mysterious spell, but it is also an ice spell.

Ning Cheng knew his own spiritual root. He had three branches: fire, wood, and earth. Now Ning Cheng has a certain understanding of the spirit root. The ice-type spirit root belongs to the alien spirit root, and the cultivators with this kind of spirit root are mainly cultivated.

The cultivation technique of the ice spirit root can only have the greatest effect when practiced by the ice spirit root and the water spirit root cultivator. For the rest of the spiritual root monks to practice, the effect will be greatly discounted.

The Seven Luminaries Ice Needle is more sinister, but it requires an ice needle artifact smaller than an ox's hair. To practice it to the extreme, this ice needle artifact can evade consciousness. This kind of thing sneaking up on others is simply impossible to guard against.

"It's a poisonous spell, but I like it." After Ning Cheng said to himself, he felt even more depressed. What's the use of liking? Don't say that he is not Bing Linggen, even if he is Bing Linggen, he can practice the Seven Lights Ice Needle, but he doesn't have the Ice Needle Magical Tool.

Ning Cheng rubbed his head in anguish. He knew that if he had gathered his qi and cultivated his spiritual sense, he could let it out. This was already amazing, but even if he didn't have his own spells, compared to others, it was far worse.

The spells he masters now, except for the wind blade, is the fire ball. These are all basic spells that have nothing to do with spiritual roots, and anyone can practice them. In addition, it is the Fire Blade Technique that he derived. As for his powerful sword glow, it can only be split because of the flying sword. If you meet an opponent who also has magic weapons, his sword glow is not worth mentioning.

Ning Cheng put away the spell jade slip in disappointment and came out of the tree hole. He had been cultivating in the tree hole for a month, and he was already bored and panicked.

Standing on the edge of the lake again, Ning Cheng was about to use a few clear waters to wash himself. Suddenly, he saw a water column rushing out from the center of the lake again. This time, the water column was exactly the same as the one he saw a month ago. With a strong spirit. The only difference is that the water column seems to be rushing higher.

After ten breaths, the water column fell again, and the heart of the lake was calm again.

Ning Cheng did some calculations, and he soon discovered that there was exactly one month between the last time the water column appeared and the one that appeared today.

With such a regular water column and a strong spiritual energy, Ning Cheng wanted to enter the center of the lake to have a look, but he felt a little discouraged when he thought that he didn't have a spell that he could use.

The Thirty-Six Spears of Xuanbing and the Seven Lights Ice Needle sounded very imposing, but how did he learn?

Can't use a sword without a gun? On this jade slip, there are thirty-six swords of Xuanbing, and he cultivated into thirty-six swords of Xuanbing by himself. Although his spiritual root does not have ice root, but he has Xuanhuangzhu, who said that he must not be able to cultivate? Thinking of this, Ning Cheng became excited again, he directly took out the flying sword, and he practiced the sword without a gun. Maybe after he has finished practicing the Xuanbing Thirty-six Spears, this spell will be renamed the Xuanbing Thirty-six Swords.

Ning Cheng's comprehension and memory are unparalleled. What he worries about is whether his spiritual roots can cultivate the Xuanbing Thirty-six Spears.

When he took out the flying sword and began to practice the spell of Xuanbing Thirty-six Spears, he immediately knew that he had thought too much before. The true qi that circulated everywhere was transformed into Xuanbing true qi without any stagnation under the magic formula of Xuanbing's thirty-six spears, and these Xuanbing true qi and external spiritual thoughts were also without stagnation. Combined, he turned his flying sword into a strange sword glow.

The only thing he needs to worry about is not that his spiritual root is not the ice root, but how long can his spiritual sense support him to control Xuanbing Jianmang?

With a "pop", Ning Cheng's flying sword fell to the ground because of his lack of divine sense. Instead of being surprised, Ning Cheng was overjoyed, he laughed and said, "I really am talented, I can even master ice spells so easily..."

Although he was excited and boasted about himself, Ning Cheng knew that his ability to cultivate the Thirty-Six Spears of Xuan Bing had nothing to do with his aptitude, it must have something to do with Xuan Huangzhu. He even suspected that with the help of Xuanhuang Yuanyuan, he had an extra ice root, but he didn't test it, he was not sure. Only when there is a chance in the future, he will go to test the magic tool and try it to see if there is really an extra ice root.

With the opportunity to practice spells, Ning Cheng took the trouble to control Feijian and used his modified Xuanbing thirty-six spears over and over again. At first, he could only cast one sword light, but with the thirty-six Xuanbing spears constantly revising in his mind, after three days, he could already cast three Xuanbing sword lights.

Five days later, Ning Cheng was already able to cast five profound ice sword beams. However, Ning Cheng also knew that with his current cultivation, the five paths of Xuanbing Sword Light were his limit. If his flying sword doesn't shoot, he can still cast two more sword beams. However, the flying sword does not shoot out, and the power of the sword glow displayed is limited. From this, it can be seen that spiritual thoughts are a good thing.

Being able to practice the thirty-six spears of Xuanbing, of course Ning Cheng would not let go of the Seven Lights Ice Needle. He didn't have a fine needle weapon, so he could only use a flying sword instead. Even if the flying sword was used instead of the flying needle, Ning Cheng was constantly revising the Seven Lights Ice Needle spell. On the tenth day, Ning Cheng was able to skillfully control the flying sword to attack. It's just that the size of the flying sword is too large, and it can't play the role of sneak attack at all.
