With a decision in his heart, Han Li naturally stopped hesitating. With a flip of his palm, the jade slip presented by the old man surnamed Jiang appeared in his hand.
This time, instead of comprehending the sword art, he began to study the method of refining the flying sword.
I had read it hastily last time, but the matter was of great importance, so Han Li naturally had to re-read it carefully.
Not long after, Han Li withdrew his divine sense and meditated with his eyes slightly closed.
According to the jade slips, there are three ways to get rid of the impurities in the flying sword.
One is the simplest and can be done with almost no external objects. It is to use the Nascent Soul Fire in the body to refine all the materials in the Feijian except for the wood attribute bit by bit.
This method is the easiest and least dangerous.
However, the various materials in his current flying sword have already been integrated into one body, and one can imagine the length of the process if he wants to forcibly separate them and refine them. I am afraid that after three or four hundred years of work, it may not be successful. And during this period, the fire of the Nascent Soul must be continuously activated, which will greatly delay one's own cultivation.
After such a long time, Han Li gave up this method almost immediately.
The second method is that the Jade Slips provide an exercise called "Jiuyan Melting Gold Jue". If you are willing to collect several special fire-attribute pills, and then retreat for seven or eighty years, you can use this exercise With the power of elixir, the impurities in the Qingzhu Fengyun Sword were forcibly expelled.
However, this method is extremely dangerous, and it will also damage part of the wood attribute energy in the flying sword, which will seriously damage the vitality of the flying sword. And those fire attribute pills are also very precious, and they are not so easy to get together.
At that time, the old man surnamed Jiang proposed to help him refine the flying sword, and he planned to use this method.
Han Li didn't like this kind of self-mutilation method either.
In this way, the last method is left, which is also the most impossible and the longest time-consuming method for ordinary people.
The old man surnamed Jiang left a message at the end of this method. On the surface, this method is just a speculation in his theory, and he has not tried it himself. But as long as you do exactly as above, you should be 80 to 90% sure. And once it succeeds, the benefits are really amazing.
This method is a method called "planting swords" by the old man.
According to the above, one only needs to find some seedlings of spiritual wood, and then find a place with rich spiritual energy to plant them, and then seal the flying sword in these spiritual trees one by one with a secret method. In this way, as the spirit wood grows, it can borrow the wood aura of the spirit wood itself, and gradually transform the other materials of the flying sword into wood attributes, and there is no need to expel anything from the flying sword.
And when the spirit wood matures, because of the long-term cultivation of those wood spirit energy, not only will these flying swords not suffer serious damage to their vitality, but their purity can reach an incredible level.
Although the power of the flying swords may not be greatly increased immediately, after a little training by Han Li, he can easily cultivate all the flying swords to the point where the hearts of the swords are transparent.
Of course, the old man surnamed Jiang didn't use such a method of getting the best of both worlds, and it was only a theoretical method, which of course had its fatal flaws.
That is, this method takes too long!
According to the above, from the beginning of planting the flying sword to the transformation of the material properties of the flying sword, the time is far longer than the above two methods.
After all, spiritual wood has to grow little by little, even if it is an ordinary spiritual wood, it cannot mature without thousands of years of careful cultivation.
During this period, not only can these flying swords not be used at all, it must also be ensured that all spirit trees will not die prematurely due to accidents. Otherwise, in case of an accident, all previous efforts will be wasted. Even if the flying sword is replanted in other spirit trees, it cannot be repaired.
As for how many years it takes to grow a sword, there is no specific limit. But one thing is for sure, the longer the sword is planted, the rarer the spirit wood is, and the more refined the flying sword will be at the end.
After reading this method, Han Li was overjoyed, and immediately decided to use this method.
The method of planting a sword may be impossible for others, but for him who has the ability to ripen plants, it is just right.
As long as the vial is fully utilized, not to mention the thousand-year spiritual wood, even the ten-thousand-year spiritual wood is a trivial matter for him.
But whether this method of using a vial to ripen spirit wood is really useful for the method of planting swords, he still has some doubts.
But anyway, this method does not require him to spend too much effort, and it only takes a little time to see the result easily, so he naturally wants to try it first.
If it really doesn't work, it's not too late to choose one of the first two methods.
Having made up his mind, Han Li shook his sleeves, and an emerald green jade box emerged.
The lid of the box flew open, and inside lay a seemingly ordinary dead green bamboo, with some roots in the lower part.
This is exactly the small piece of golden thunder bamboo with roots that Han Li deliberately left behind after refining the flying sword, as a backup.
Although it was not mentioned in the jade slips, but using spirit wood which is the same as the main material of the flying sword to grow the sword, the natural effect will be better. And now that I know that the leaves of the Golden Thunder Bamboo can be used to refine the more powerful Golden Gang Extinguishing Demon Thunder, I just picked some by the way, so that I can use it as a spare.
With a thought, Han Li summoned the second Nascent Soul again, and handed over the wooden box and a flying sword to it.
Let him try it with a flying sword first, if it is really feasible, he will naturally spawn a large number of golden thunder bamboos, and put the rest of the flying swords in the bamboo.
After the second Nascent Soul left with the jade box and flying sword in hand, Han Li closed his eyes and rested for a while. After opening his eyes again, he took out another milky white vial.
Lifting his neck, and dripping a drop of real toad liquid from the bottle into his mouth, Han Li finally started his real cultivation.
No matter how good the treasures are, and how miraculous the supernatural powers are, without a certain amount of mana to support them, they are still like rootless duckweeds.
This point, Han Li has been very clear for a long time.
I saw him making a tactic with both hands, his body was shining with gold, and at the same time, the real magic behind him emerged again.
With three heads and six arms, with a movement of the six arms, each pinches out a mysterious method, and at the same time sits with both legs cross-legged, unexpectedly also adopts a cultivation posture.
At the same time as the golden light flashed on Han Li's body, a circle of golden halo appeared on the Brahma Saint's true magic figure.
The halo was so huge that it enveloped all the dharma figures, and countless golden runes poured out from the six golden hands, and after circling and dancing in the halo, they sank into the body of the dharma figures one after another.
On the other hand, Han Li had no expression on his face, the golden scales on his body were faintly visible, and the aura was erratic on the surface of his skin, appearing extremely mysterious...
There is no time to practice, day by day, month by month passed in a blink of an eye, but the door of the secret room has never been opened again.
During this period, only the second Nascent Soul manipulated a giant ape puppet to appear occasionally in the medicine garden, and then disappeared strangely.
On the other hand, outside the cave, those mid-level monsters from Heiyin Mountain brought a large number of rare materials in exchange for Mu Linghua several times, each of them looked like a catastrophe was imminent.
As a result, the Second Nascent Soul spent some time at will to ripen some Muling flowers, and then let the crying soul change into Han Li's appearance to hide from these monsters, and easily concluded the deal again.
Seeing that the crying soul could still produce so many Muling flowers, these monsters finally breathed a sigh of relief, and their panic disappeared a lot.
Time flies, autumn and winter come, and more than a hundred years have passed slowly.
Nothing major happened on the giant island, as if it would continue to be calm like this.
But on this day, an astonishing celestial phenomenon suddenly appeared in the sky above the mountain where Han Li's cave was located.
Suddenly there was the sound of continuous thunderbolts in the high sky, and then milky white spiritual clouds emerged out of thin air, and then all gathered towards the top of the mountain.
At the peaks and peaks within a radius of ten thousand miles, colorful spots of light suddenly emerged from the underground trees at the same time, all shooting towards the sky.
And after reaching a certain height, these light spots burst and burst like bubbles under the expansion and contraction of the surface, turning into pieces of five-color light, and then lasing away towards the location of Han Li's cave.
In just a cup of tea, the giant mountain where Han Li was located was covered layer by layer with unusually thick five-color rays of light, and it was completely dyed in five colors.
But another celestial phenomenon appeared in the sky!
At this moment, those milky white spiritual clouds have condensed into a huge cloud ring with a diameter of more than a hundred miles, and in the center of the cloud ring, gusts of green hurricanes are forming out of thin air. They were drawn into the cloud ring one after another, and then the torn pieces merged together again.
As the hurricane grew stronger, more and more five-color auras were drawn into the sky, and finally the color of the hurricane changed from blue to strangely colorful, but the five-color light that flew from thousands of miles away did not decrease at all. The light curtain of the entire giant mountain wrapped below is a little thicker than before.
Such an astonishing and strange sight naturally alarmed all the beasts in the Black Hidden Mountains, as well as some intelligent low- and middle-level monsters.
As soon as the ordinary beasts felt the huge spiritual pressure coming from the direction of the sky, they were all frightened and lay down on the ground trembling.
And some intelligent low-middle-level monsters flew out of their residences one after another, and rushed towards the location of Han Li's cave.
But after being thousands of miles away from the celestial phenomenon, all the monsters seemed to have encountered an invisible boundary, and they fell to the ground one after another.
They looked at the five-colored giant mountains and the strange cloud rings in the sky in the distance, and they all looked panic-stricken.
The bull-headed beast, the three-headed giant python, and other monsters that had made deals with Han Li also appeared nearby.
They naturally recognized the place under the celestial phenomenon at a glance, and immediately gathered together in shock, looking at each other and couldn't help but look at each other.
"That person is about to advance! With such an astonishing celestial phenomenon, could it be that that person is about to advance to the Lingshuai level?" The head of the three giant pythons made a hoarse and unpleasant voice, and said first.
"Probably so. Ordinary small realm promotions will not have such signs." The little beast with the head of the cow looked at the cloud ring in the distance, and slowly affirmed.
