Sun Xiaofei returned home, said hello to everyone, and passed through the teleportation array in the family and teleported directly to the secret cave. Sun Xiaofei walked out of the teleportation array with an indifferent face, and walked straight towards a passage outside under the awe-inspiring gaze of the two guards guarding the teleportation array outside.

At the end of the passage, there is a vast space with many buildings protected by layers of light curtains, and many caves and stone chambers have been dug out of the surrounding mountain walls, and the earthy smell of the caves mixed with various smells comes to the face.

The caves and stone chambers here are used for a variety of purposes, mainly for cultivating and refining weapons or elixirs, and some for storing important supplies.

There was a bustling scene of people coming and going, and some carts loaded with goods were driving into another cave. There were cold-eyed guards around to monitor everyone, and when they saw Sun Xiaofei, they all saluted respectfully, and their eyes were full of awe and worship.

Sun Xiaofei glanced around and went straight to the largest stone room. Wherever he walked, people automatically stepped aside and let him gallop by.

In the main hall, Sun Xiaofei summoned the principals who were in charge of the affairs here, and asked them about the materials needed to build the Spirit Gathering Array, as well as the progress of various foundation constructions.

Those principals did not dare to slack off, and they all answered his questions truthfully, and explained the details of all the big and small things one by one.

Sun Xiaofei was silent after listening to it, and had a general understanding of various situations and data. His mind was spinning rapidly, silently calculating the difficulties and possibilities encountered in the implementation of the Spirit Gathering Array.

Seeing that he didn't speak, those principals all quieted down, and in an instant, the entire spacious hall was quiet, and everyone's eyes fell on Sun Xiaofei, waiting for his orders and arrangements.

After a while, Sun Xiaofei said leisurely: "Let's go down first." ”

Everyone left with him, Sun Xiaofei waited for them to leave, touched the storage bracelet on his hand, and during this time, those superb spars and various construction materials that had been inspected by him were all collected by him in the storage bracelet.

Sun Xiaofei suddenly got up and flashed out, his figure was as fast as lightning, and soon appeared in the deepest part of the mountain. There is a huge square in the depths of the mountain, surrounded by hundreds of huge stone pillars, which are carved with various cumbersome formation secret patterns.

This place is full of powerful and countless various defensive formations, attack formations, phantom formations and prohibitions, these protective forces form layers of energy light curtains, and all kinds of chaotic power mysteries completely cover everything inside, making people unable to see the situation in front of them clearly.

Sun Xiaofei seemed to be familiar with all this, his footsteps did not stop, and his figure shuttled through various formations, approaching the center. Most of these formations were arranged by him himself, so he naturally knew how to crack them. Some other formations arranged by other powerhouses didn't have much effect on him, with his current formation ability and cultivation, no formation could be difficult to stop him.

As soon as the light flickered, Sun Xiaofei's figure appeared in the square, and his eyes looked around vigilantly. This place looks like a square from a distance, but it is not at all, but rather like a huge high platform. There are hundreds of huge secret stone pillars around the high platform, each stone pillar is at least a few zhang thick, ranging from 100 meters to hundreds of meters high, and the location of the place also contains some kind of mystery. The stone pillars emitted a faint light, and if you look closely before getting closer, you will find that each stone pillar here is of very high quality, and the huge energy fluctuations emitted by it.

These energy fluctuations contain the power of the five elements, and the formation arranged on the basis of the power of the five elements is powerful and has all kinds of incredible functions.

"Who?"

Suddenly, there was a broken cry, and three powerful figures slowly appeared beside Sun Xiaofei, Sun Xiaofei stood still, with a harmless smile on his face.

"It's you. ”

Three old men in dark gray robes appeared on the high platform, and one of them had a thin face, and saw Sun Xiaofei's appearance clearly, and said with a smile.

"Meet the third grandfather, the fourth grandfather, Ning Ye. Sun Xiaofei bowed and saluted respectfully.

These three people are the only three remaining powerhouses of the older generation of the Dagus family, and Sun Xiaofei's other three battle swords were taken out by them. However, Sun Xiaofei also refined another long sword weapon for them, which could be regarded as compensating for their losses.

"No need to be polite. Ryan, why do you have time to come here today?" asked the emaciated third grandfather.

The other two old men also came over, one of them looked a little similar to the third grandfather, and his body was also relatively thin.

Another old man with thick eyebrows and big eyes is an elder of the Dagus family, named Haining. Refining the way of the sword and cultivating the earth system exercises, the three of them all have sword sect cultivation, and the old man who was called the third grandfather by Sun Xiaofei has reached the peak realm of the sword sect.

"I'll come over to see how Xiaohui and Xiaojin are doing. Sun Xiaofei walked over and said with a smile.

"They are in good condition and everything is going well. ”

"I went in. ”

Sun Xiaofei chatted with them for a few words, and then walked to the stone pillar.

The three of them glanced at each other, and then flew away, their bodies hidden, and continued to watch over the place.

Sun Xiaofei's figure suddenly disappeared in the stone pillars, and those stone pillars formed a formation, each scene was different, completely covering up the situation inside. Only a person like Sun Xiaofei who is familiar with the various formations here can move freely in the various formations and arrive at the destination he is going to. If someone who doesn't understand the formation breaks in, they will encounter all kinds of dangers, touch those powerful formations, fall into a dilemma, or be bombarded by the formation.

In front of Sun Xiaofei, two huge pools appeared, and there were two huge figures soaked in the pool, which were Xiaohui and Xiaojin. There was a foul smell everywhere, and the pool was mixed with the smell of various materials, and it became very sticky.

The liquid in the Xiaohui Pool is black, and the liquid in the Xiaojin Pool is brown. Although the colors are a little different, the energy fluctuations emitted by the two pools are equally amazing. The rich energy formed a thick fog that filled the pool, absorbing and transforming their bodies by the two beasts, causing them to transform at a slow pace.

Around the pool, ten spirit gathering arrays need to be built, each of which is built with the best spars, and now Sun Xiaofei has completed these ten spirit gathering arrays, and the operation of the spirit gathering array has played a huge role, and at the same time, it also consumes a large number of spars. When the golf ball sends the best spar, it can be continuously replenished.

Sun Xiaofei was able to rely on the memories left in his mind to reproduce the large spirit gathering array of the master sect here. The Large Spirit Gathering Array is composed of ten small Spirit Gathering Arrays, which are of vital help and effect on cultivation.

In order for Xiao Hui and Xiao Jin to advance smoothly, Sun Xiaofei spared no effort to rebuild two cultivation pools within the formation. Originally, the Spirit Gathering Array needed the support of a core array, so it was divided between the two pools. In this way, it greatly increased the difficulty of building the Spirit Gathering Array.

Whether it is the input of various construction materials, it must be multiplied. The portrayal of the Ten Gathering Spirit Formation Formations also requires more and greater effort and energy.

However, Sun Xiaofei had no regrets about this, because the construction of the Spirit Gathering Array was for Xiaohui and Xiaojin, and it was also for the future of the Dagus family, even if he had to pay a big price, he was willing.

After Sun Xiaofei carefully checked the situation of Xiaohui and Xiaojin, with a wave of his arm, the void light flickered, and a dense variety of precious materials suddenly appeared, including metallic materials, fire and earth materials, etc., as well as many medicinal herbs and herbs that could not be named.

Sun Xiaofei mentally manipulated these materials to fall into two pools respectively, Xiaohui cultivated the earth system and the fire system, and the materials added were mostly fire and earth, and Sun Xiaofei also added some drugs and materials to speed up the transformation, so that Xiaohui could more easily absorb and refine in the short term and speed up its evolution.

Xiao Jin needs gold materials, but some metal materials cannot be directly absorbed, and must be refined through special refining before they can be turned into energy that can be absorbed and refined. Sun Xiaofei had already prepared for this.

I saw Sun Xiaofei methodically throwing all kinds of materials into Xiaojin's cultivation pool, and some of the materials were packed in bottles or preserved in special methods. There were even some that he needed to refine before he could use them.

After all the materials were put into the pool, Sun Xiaofei quickly pinched the trick with both hands, and all kinds of mysterious magic decisions were punched into the two pools by him, and the two pools boiled, and a large amount of spiritual mist emerged, and the spiritual mist turned into water droplets and fell back into the pool, and the pool was full of amazing spiritual energy.

Sun Xiaofei's method changed, and the liquids in the two pools slowly rotated, forming a vortex around Xiaohui and Xiaojin, bursting out with a strong suction, swallowing all the surrounding energy.

The spiritual veins under the entire mountain peak were affected by this suction, and they all turned into long dragons of spiritual energy, surging towards the pool. The two pools were like whales absorbing water, devouring these spiritual energies, transforming them into streams of incomparably pure energy, which penetrated into the bodies of Xiao Hui and Xiao Jin in the center of the pool, making their bodies constantly tempered and strengthened, and then tempered and strengthened......

Sun Xiaofei walked to the side, stared at this scene with a calm face, and muttered: "I have already done everything for you, and the rest is only to break through by yourself." ”

Sun Xiaofei's figure flickered, and then he appeared in front of the Spirit Gathering Array next to the pool. Take out the best spars placed in the storage bracelet, replace those spars whose energy is close to exhaustion, re-depict the formation, condense the surrounding heaven and earth aura, and inject it into the two pools, keeping the energy in the pools always in a full state.

Sun Xiaofei's speed is not very fast, he needs to inspect each Spirit Gathering Array, those replacement of the best crystals, need to carefully carve the formation, so that each Spirit Gathering Array can play a role, and the time and energy spent on this are very large.

By the time he had done all these things, a slight sweat had appeared on his forehead. Sun Xiaofei's eyes were still very bright, looking at everything he had arranged with his own hands, and he felt a great sense of satisfaction in his heart. Before Xiaohui and Xiaojin break through, Sun Xiaofei will not let those children of the family come here to cultivate for the time being, so as not to cause repercussions.

Sun Xiaofei turned around and left, and the task of taking care of this place was handed over to the powerhouses of the Dagus family. He also had to go back to deal with Mu Wanqing's affairs, if the latter was taken away by the elf queen, how would he explain it to the Mu family. So as not to cause some unnecessary trouble because of this incident, and cause cracks in the relationship between the two families.
