After several months of continuous trial and practice, Lin Jiu didn't dare to say anything else, but he already had a strong confidence in refining various symbols.

After all, he had accumulated a lot of experience from studying and trying day and night during this time, and the only thing that worried Lin Jiu was that after this period of consumption, the materials in his hands were also reduced by one percent, that is to say, if there were too many mistakes in the future refining, it was likely to lead to the lack of materials.

Lin Jiu was also quite helpless about this, after all, the master of this cave mansion was a formation mage, and his refining level was naturally stronger than his own, and the materials he prepared were naturally more than enough to arrange the magic circle, but for various reasons, he actually died before he could leave the master, leaving these materials to Lin Jiu.

If it was outside, it would be fine, although these materials were precious, Lin Jiu believed that as long as there was enough time, he would definitely be able to find them.

But now that I am in this cave, it is wishful thinking to get the materials, and every piece of material wasted in my hand is one less piece, and after this period of refining, I have lost nearly three layers of materials, and if the success rate is not enough, it is really possible to have an embarrassing situation of insufficient materials.

After calculating the number of materials, Lin Jiu became more and more cautious, and before each refining, he had to go through the refining process in his mind carefully, and only after confirming that there were no problems did he start refining.

Rao is like this, Lin Jiu still has waste materials in the next refining process, but fortunately, Lin Jiu is calm, every time there is waste materials, he immediately stops refining, and only starts refining when he is calm and his state is at its best.

Not to mention, in this way, the refining of symbols gradually became smoother.

There was no time in the cave, and I don't know how long it took, Lin Jiu finally refined all the spiritual materials into various ancient symbols.

And the girl was not idle, when Lin Jiu was refining the magic circle, she also carefully installed these materials one by one according to the drawings of the magic circle.

"Phew, the circle is finally healed. Looking at the depleted spiritual material, Lin Jiu let out a sigh of relief, during this period of time, in order to refine more spiritual power, sometimes he even slept thinking about the technique of refining the weapon, and now that the magic circle has been completed, the hanging heart can finally be put into his stomach.

"The circle is set. After the girl put the last piece of spiritual material in the magic circle, she also let out a long breath and said excitedly.

"Put the spirit crystal on and try it. After staying in the cave for too long, Lin Jiu also became quite anticipating.

The girl nodded, her face flushed, and she took the spirit crystals handed over by Lin Jiu and placed them in the various grooves on the teleportation circle.

"Open. Seeing that the magic circle was arranged, Lin Jiu immediately had a flash of spiritual light in his hand, and a spiritual power entered the magic circle.

When the spiritual power entered, the magic circle lit up, and the white spiritual light flowed quickly along the lines on the magic circle, and soon all the runes were lit up one by one.

"It worked. Lin Jiu and the others were immediately overjoyed, and after the magic circle calmed down, they immediately had a flash of inspiration on their bodies and fled into the magic circle one after another.

"Teleport!"

When the two of them entered the magic circle, they couldn't wait for a flash of spiritual light in their hands, and a spiritual power entered with it.

"Hum ......" The entire magic circle was then stimulated, and the two of them were instantly wrapped in white aura.

The two of them only felt a tightness on their bodies, as if they were being pulled by a huge force.

"Haha, it worked. The girl, who had been frowning, finally burst out laughing.

For so many days, the girl has basically looked cold, and now she is naturally overjoyed to be able to escape and ascend to heaven.

However, to the surprise of the two, as the aura flashed on the two of them, the power on the two of them suddenly stagnated, and this power disappeared.

"What's going on?" the girl asked with a surprised look at Lin Jiu.

"I don't know. Lin Jiu shook his head and said.

"Check quickly, is there something wrong with the magic circle you have refined?" the girl said with an eager expression.

"Impossible, I refine every piece of spiritual material exactly according to the size on the classics, and the runes are definitely fine. Lin Jiu thought about it carefully and said with a serious face.

"What's the problem then?" said the girl, angrily.

Lin Jiu's brows furrowed slightly, but his eyes searched around in the magic circle.

"Huh, what is this?"

Soon, Lin Jiu's gaze was drawn to a stone in the groove in the middle of the circle.

It wasn't until now that he realized that it wasn't the problem with the array, but that the spiritual power of the spirit crystal placed in the center of the circle was exhausted, so the teleportation failed.

Seeing this, Lin Jiu and the two couldn't help but look at each other, he remembered clearly that there was a medium-grade spirit crystal in this groove at the beginning.

But he didn't expect that a piece of intermediate-grade spirit crystal would not be able to drive this teleportation array.

"It seems that if you want to activate this magic circle, you have to have a high-level spirit crystal or above. Lin Jiu rummaged through the belongings on his body and couldn't find a single high-grade spirit crystal, so he said disappointedly.

"I wonder if the best spirit crystal can be used?" Seeing Lin Jiu's disappointed face, the girl was inexplicably touched in her heart, and she didn't know why she asked when she was still hesitating.

"Top-grade spirit crystal?" Lin Jiu was startled, for so long, he had seen the top-grade spirit crystal in the valley once before, and it was still from a distance.

"Could it be ......" Lin Jiu secretly guessed in his heart.

The girl nodded, and agreed.

Lin Jiu didn't say anything more, just nodded and said, "If there is a top-grade spirit crystal drive, the possibility of us escaping from the cave is at least two levels higher." ”

"If that's the case, then give it a try. The girl said with a flash of inspiration in her hand, and a seemingly ordinary box appeared in her hand.

The whole box looks very quaint, but it doesn't feel any precious.

"There are no spiritual power fluctuations on this box, and there are no prohibitions, could it be that there are really top-grade spirit crystals in here?" Lin Jiu muttered in his heart.

You must know that the spiritual power of the best spirit crystal is extremely abundant, and if you just look at the strength of the spiritual power, it is not even inferior to the ordinary high-grade elixir, so if there is no special collection method, there will definitely be spiritual power leakage, so that it will be detected by other spiritual cultivators.

Seeing Lin Jiu looking at herself with a puzzled expression, the girl didn't say anything, her hand flashed, and the box opened with a bang, followed by an abundant spiritual power.

Lin Jiu just took a light breath, and suddenly felt refreshed, and even his cultivation, which had been stagnant, seemed to be about to move.

"This superb spirit crystal is really magical, in terms of the abundance of spiritual power, I am afraid that even the high-grade pills are inferior, this world is so big, it is really wonderful. Lin Jiu sighed in his heart.
