With a decision in his heart, Han Li naturally no longer had any doubts, and with a flip of his palm, the jade slip given by the old man surnamed Jiang appeared in his hand.

This time, instead of comprehending the sword technique, he began to study the method of refining the flying sword.

He had already read it in a hurry last time, but the stakes were so high that Han Li naturally had to read it again.

It didn't take long for Han Li to withdraw his divine thoughts, his eyes narrowing slightly.

According to what the jade slip says, there are three ways to get rid of the impurities in the flying sword.

One of the easiest, almost without any sunset. It is to use the primordial infant fire in the body to refine all the materials other than the wood attribute in the flying sword little by little.

This method is the simplest and least dangerous

However, the various materials in his current flying sword have long been fused, and if he wants to forcibly separate and refine them, the long process can be imagined. I'm afraid that after three or four hundred years, it may not be able to succeed. And during this period, "you must keep urging the fire of the primordial infant, and your own cultivation will be greatly delayed."

For such a long time, Han Li gave up this method almost immediately.

The second method is that the jade slip provides a partial method called "Nine Flames Molten Gold Decision", if you are willing to collect several special fire attribute pills, and then retreat for seventy or eighty years, you can use this exercise plus the power of the pill to forcibly expel the impurities in the green bamboo bee cloud sword.

However, this method is extremely dangerous, and it will also damage some of the wood attribute essence in the flying sword, which will greatly damage the vitality of the flying sword. And those fire attribute pills also cherish abnormalities, 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 was ready to use this method.

Han Li also didn't fancy this method of self-harm.

In this way, the last method is left, and it is also the most unlikely and time-consuming for the average person.

The old man surnamed Jiang left a message at the end of this method, on the surface this method is just a theoretical speculation on his part, and he has not tried it himself. However, as long as it is done exactly as above, there should be a certainty. And once successful, the benefits are staggering.

This method is a method called "planting sword" by the old man.

According to the above, as long as you look for some spiritual wood seedlings, you will find a place where the spiritual energy is rich and plant, and then use the secret method to seal the flying sword in these spiritual trees one by one. In this way, as the spirit wood grows, it can borrow the wood aura of these spirit trees themselves, and the other materials of the flying sword can be gradually converted 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 spiritual qi, these flying swords, not only will not be greatly damaged, but also their own purity can reach an incredible level.

Although it was not necessary that the power of the flying swords would increase immediately, with a little cultivation in the future, Han Li would be able to easily cultivate the flying swords to the point where the sword heart was clear.

Of course, such a method of getting the best of both worlds, the old man surnamed Jiang did not adopt it, and it was only a theoretical means, of course, it had its fatal flaws.

That's how long it takes to do it!

According to the above, from the beginning of planting the flying sword to the transformation of the flying sword material, the time is longer than the above two methods.

After all, the spirit tree must grow little by little, even if it is an ordinary spirit wood, without thousands of years of careful cultivation, it will not be able to mature at all.

During this period, not only could these flying swords not be used in the slightest, but they also had to ensure that all the spirit trees would not be broken due to accidents. Otherwise, if there is an accident, all the work will be wasted. Even if the flying sword is replanted into other spirit trees, it will not be able to make up for it.

As for how many years it will take to grow a sword, there is no specific boundary. But one thing is certain, the longer the sword is planted, the rarer the spirit wood becomes, and the more the final essence of the flying sword can reach the extreme.

After Han Li saw this method, his heart was overjoyed, and he immediately decided to use this method.

The method of cultivating a sword may be impossible for others, but for him with the ability to ripen plants, it is just right.

As long as he makes full use of the vial, not to mention the thousand-year-old spirit wood, even the thousand-year-old spirit eye is also a trivial matter for him.

But he still had a little doubt about whether this method of borrowing a vial to ripen the spirit wood was really useful for the method of cultivating swords.

But anyway, this method doesn't require him to spend too much effort, as long as it takes a little time, it can be easily seen, so naturally try it first.

If it really doesn't work, it's never too late to choose one of the first two methods......

With his mind set in his mind, Han Li's sleeves flicked, and an emerald green jade box emerged.

The lid of the box flew open, and there was a seemingly ordinary withered green bamboo lying inside, with some roots in the lower part.

This was exactly what Han Li had deliberately left behind after refining the flying sword in the first place, and he had left a small piece of golden thunder bamboo with roots for backup.

Although it is not said in the jade slip, it will naturally have a better effect if the sword is planted with a spirit wood that is the same as the main material of the flying sword. Moreover, now that he knew that the Golden Thunder Bamboo Leaves could be used to refine the more powerful Golden Gang Demon Slayer Thunder, he happened to pick some by the way, so that they could be used as backups, and with a movement of his mind, Han Li summoned the Second Yuan Infant again and handed it the wooden box and a flying sword.

Let him try it with a flying sword first, if it is really feasible, he will naturally give birth to a large number of golden thunder bamboos, and put the rest of the flying swords in the bamboo one by one.

After the Second Yuan Infant left with the jade box and flying sword in his hand, Han Li closed his eyes for a while, and after opening his eyes again, he took out a milky white vial.

After raising his neck and dripping a drop of True Toad Liquid from the bottle, Han Li finally began his true cultivation.

No matter how good the treasure is, no matter how magical the magic is, if there is no certain amount of mana support, it is still rootless.

Han Li had been well aware of this from a long time ago.

I saw that he pinched his hands, and the golden light on his body flashed, and at the same time, the true magic behind him resurfaced.

The three-headed and six-armed law phase "Under the movement of the six arms, each pinched out a mysterious hand, and at the same time sat cross-legged, and actually made a cultivation posture.

At the same time as the golden light flashed on Han Li's body, a golden halo also appeared in the Divine Saint True Magic Phase.

This halo was incomparably huge, enveloping the golden capital of the Law Phase, and countless golden runes kept pouring out from the hands of the six pinching golden hands, and then after circling and flying in the light leather, they all submerged into the Law Phase's own body.

Han Li, on the other hand, was expressionless, the golden scales on his body loomed, and the aura flowed erratically on the surface of his skin, looking extremely mysterious......

There are no years of cultivation, day by day, month and month have passed in the blink of an eye, but the door of the secret room has never been opened again.

During this period, the second infant can only be seen manipulating a giant ape puppet to occasionally appear in the medicine garden, and then disappear strangely.

However, outside the cave mansion, those middle-level demon Daoists of the Black Hidden Mountain took a large number of rare materials in exchange for Mu Linghua several times, and they all looked like a catastrophe was coming.

As a result, the second primordial infant took some time to ripen some Mu Ling flowers at will, and then let the crying soul change into Han Li's appearance to hide from these monsters, and easily made this deal again.

Seeing that the crying soul could still take out so many other spirit flowers, these monsters finally breathed a sigh of relief, and the panic disappeared a lot

Time flies, autumn goes to winter, and more than a hundred years of time have passed.

Nothing major happened on the island, as if it would remain calm forever.

But on this day, an astonishing celestial phenomenon suddenly appeared above the hill where Han Lidong Mansion was located.

I saw that there was a sudden sound of thunderclaps in the clear sky high in the sky, and then there were breasts

White spirit clouds appeared out of thin air, and then gathered towards the top of the mountain.

At the peaks of the mountains and mountains within a radius of 10,000 miles, colorful points of light suddenly emerged from the underground trees at the same time, and they all shot high into the air. And after reaching a certain height, these light spots rose and contracted, and the foam burst one after another, turning into pieces of five-colored light, and then shot away towards the place where Han Lidong Mansion was.

Almost as soon as it was just a cup of tea, the giant mountain where Han Li was located was wrapped in layer after layer of condensed and abnormally thick five-colored light, completely dyed into a five-color glow.

But there was another celestial phenomenon in the sky!

I saw that those milky white spirit clouds had condensed into a huge cloud ring with a diameter of more than 100 miles at this moment, and in the center of the cloud ring, a stream of Qingmengmeng hurricanes was forming out of thin air.

With the growth of the hurricane, more and more five-colored spiritual light was swept into the sky, and finally the color of the hurricane changed from cyan to strange colors, but the five-colored light flying from thousands of miles away around did not decrease at all, and the light curtain that wrapped the entire giant mountain below was a little thicker than before.

Such an astonishing and strange scene naturally alarmed all the beasts in the Black Hidden Mountain Range, as well as some low- and middle-level monsters with spiritual intelligence.

As soon as the ordinary beasts felt the huge spiritual pressure coming from the direction of the celestial phenomena, they were all frightened and lay on the ground trembling non-stop, and the fierce beasts that were usually fierce were terrified at the moment, their bones were loose and weak, and their limbs were weak.

And some low- and middle-level monsters with spiritual intelligence flew out of their residences one by one, and hurriedly shot towards the location of Han Li's Mansion.

But after being thousands of miles away from the heavens, all the monsters seemed to have touched an invisible boundary, and they fell one after another and disappeared.

They looked at the five-colored giant stops in the distance and the strange cloud rings in the sky, and they all looked panicked.

Monsters such as the Ox-headed Beast and the Three Giant Pythons that had traded with Han Li also appeared nearby.

Naturally, they recognized at a glance what was beneath the celestial phenomenon, and they immediately came together in shock, and they couldn't help but look at each other as they looked at each other.

"Is that person going to advance! Such an amazing celestial phenomenon, could it be that person who wants to advance to the spirit handsome level existence?" The middle head of the three giant pythons made a hoarse and ugly voice, and said first. "Probably so. Ordinary small realm promotions will not show such signs. The bull-headed little beast looked at the cloud ring in the distance and slowly affirmed.
