The area of the underground cave is not large, but Lin Chuan has no problem repairing the puppet inside, fortunately, he has a lot of precious materials on him, and there are also a lot of ready-made materials on the puppet in the early stage of distraction last time, so there is no problem in repairing it.

Three days later, Lin Chuan completely repaired the puppet and refilled it with spirit stones, which was able to support the puppet to continue fighting.

After putting away the puppet, Lin Chuan didn't leave immediately, this place is dangerous everywhere, and some preparations must be made, Lin Chuan thought about it carefully, and decided to cultivate the Sky Splitting Sword here first.

With a flash of silver light, the Sky Splitting Sword appeared in front of him, the sword body was a foot long, the silver light flowed, and mysterious silver runes loomed on the sword body, and strong sword qi fluctuations emanated from it.

Although the Sky Splitting Sword is still only a sword fetus, it has reached the level of a magic weapon, if you want to cultivate the sword fetus into the Yuan Spirit Flying Sword, you need to infuse a lot of spiritual energy, and at the same time, you also need a lot of precious materials, and you also need special sacrificial techniques.

Of course, the sacrificial refining technique Heaven Splitting Sword Technique has been introduced in detail, and Lin Chuan has also studied it for a while, and he has roughly understood how to change it, but the sword fetus must grow to a certain level before he can start refining the Yuan Ling Flying Sword.

The sword fetus itself must be nourished by mana in the monk's body, so that it can improve with the improvement of the monk's strength realm, which is a long process that takes a lot of time.

It's just that there is a devouring secret technique on the true solution of the sword, which can allow the sword fetus to devour other sword fetuses to strengthen oneself and greatly shorten the time for recuperation, but there are also disadvantages to doing so.

In this way, the growth rate of the sword fetus is too fast, and it is easy to exceed the range that the monk can control, and it is easy to cause backlash, and sometimes it can even cause the tragedy of the sword fetus being exposed and even the monk falling together.

This is a shortcut, and at the same time it is full of danger, for others, this flaw is fatal enough, the sword cultivation of the Heavenly Sword Gate only has a sword fetus in the body, there is no Yuan Baby, the sword fetus explodes, and they have no way to live.

In addition to having a sword fetus, Lin Chuan also has a normal Yuan Infant in his body, so there is no such problem, and at the same time, Lin Chuan's strength is far higher than his realm, even if the sword fetus grows rapidly, it is not easy to get out of his control, and the risk is much smaller.

Lin Chuan took a closer look at the Sky Splitting Sword, the Sky Splitting Sword was different from other magic weapons, and he had a feeling of blood connection, as if the Sky Splitting Sword was a part of his life, he could already clearly feel that the Sky Splitting Sword had grown a lot compared to when it was just refined, but it was still far from catching up with the improvement speed of Lin Chuan's realm.

Although the current power of the Sky Splitting Sword is also very strong, it is a little insufficient compared to the degree of the Sky Splitting Sword, Lin Chuan decided to take advantage of the current situation to increase the power of the Sky Splitting Sword, of course, the method is to devour other sword fetuses, this secret technique is not the first time he has used it.

With a flip of his left hand, a sealed sword fetus emerged, it was the sword fetus of the Heavenly Sword Sect disciple who had been collected by him in front of him, but it was a little dim and was sealed by Lin Chuan's mana.

I saw Lin Chuan's hands stretched out, pinching in front of him like a wheel, his fingers brought up a phantom, and mysterious spirit patterns were shot out from his hands and integrated into the Sky Splitting Sword.

In an instant, the silver light of the Sky Splitting Sword bloomed, and countless silver spirit runes appeared, wandering around the sword's body, looking extremely mysterious, and at the same time, a powerful sword qi spread out from it.

Then suddenly, a silver vortex appeared above the Sky Splitting Sword, and silver filaments poured out from the silver vortex, and these silver filaments were sword qi threads.

The silver sword qi silk thread extended from the vortex like an octopus tentacle, shaking in the air, Lin Chuan's expression moved, and the seal on the sword tire next to him was instantly lifted.

Almost at the moment when the seal was lifted, the sword fetus flashed, and suddenly it was very spiritual and wanted to escape, but before it could fly far, a puff of silver silk thread rushed up from behind, winding around the sword fetus like a spiritual snake.

Snort ......!

As if sensing the danger, the sword fetus bloomed with dazzling light, struggling hard, trying to break free from it, some silver silk threads were broken by the sword fetus, but more and more silver silk threads were wound up later, like spring silkworms spinning silk, wrapping the sword fetus layer by layer.

The sword fetus itself was already not much strength, it was wrapped layer by layer, and the power of resistance became weaker and weaker, and finally it was wrapped into a silver cocoon-like thing, which was pulled by the silver silk and slowly flew in the direction of the silver vortex.

The silver cocoon was swallowed by the silver vortex, and the silver light on the Sky Splitting Sword flickered for a while, and the sword qi fluctuations also became a little unstable, sometimes strong and sometimes weak, and those mysterious runes turned even more powerfully.

Lin Chuan was still pinching the trick quickly, and the mana in his body was running, turning into a sword element and injecting it into the Sky Splitting Sword.

After about a pillar of incense, the wrapped sword tire completely disappeared into the silver vortex, as if it had entered another dimension, and the heterochromatic vortex also contracted violently, turning into a small silver dot and disappearing.

Suddenly, the silver light on the Sky Splitting Sword trembled wildly, and even more violent fluctuations emanated from it, Lin Chuan understood that at this time, the Sky Splitting Sword was already refining the sword fetus that had been swallowed into it.

Lin Chuan didn't dare to slack off, injected his mana into it, and made every effort to assist the sword fetus in the refining of the Sky Splitting Sword, Lin Chuan could clearly feel that there was a fierce resistance from the devoured sword fetus, the more powerful the sword fetus, the stronger its spirituality, and the greater the difficulty of refining, Lin Chuan knew very well.

The sword fetuses this time were much stronger than those harvested by Xiao Lingtian, so the difficulty of refining them had increased by I don't know how many times, and the time alone exceeded a lot.

A day later, the will to resist in the Sky Splitting Sword was almost imperceptible, and three days later, a dazzling silver light bloomed, and the aura of the Sky Splitting Sword instantly increased a lot, only to see that there were some more mysterious spirit patterns on the Sky Splitting Sword at this moment, which looked very mysterious.

Lin Chuan's heart was overjoyed, he could clearly feel the enhancement of the power of the Sky Splitting Sword, and his confidence suddenly increased, and at the same time, he couldn't wait to get up, secretly looking forward to it, thinking that he didn't know how far the Sky Splitting Sword would grow if he devoured all the sword fetuses.

Lin Chuan's heart was hot, and he immediately took out the other sword fetus, and continued to urge the secret technique to assist the Sky Splitting Sword to expand and devour, with the previous experience, the back devouring was quite smooth, and the stronger the power of the Sky Splitting Sword, the easier it was to devour.

Time passed quietly, Lin Chuan stayed in the underground cave for a month, this time is nothing to the monk, in the past month, the Sky Splitting Sword has devoured and refined all the sword fetuses collected by Lin Chuan, and the power has increased several times.
