After the personnel were gone, the mound returned to silence.

Lu Tianji fell into deep thought, "I didn't expect that there was actually a seven-grade sword buried under the cultivation array, I didn't even notice it before, it seems that my strength is still far from enough." In this huge mound, there is a long history, the composition of weapons is complex, anything can happen, and only strength is the only guarantee. ”

"Fortunately this time, the Yuehua Sword has long been damaged, and its power is far less than it was back then, so I can absorb its aura unconsciously, if it is a complete seven-grade treasure weapon...... The consequences are unimaginable! ”

So in the following days, Lu Tianji worked hard and continued to practice hard.

He used the Ten Thousand Weapon Technique and the Cultivation Array to continuously absorb the surrounding Heaven and Earth Aura, the essence of all things, and the Qi of Ten Thousand Soldiers.

In a blink of an eye, half a year has passed, and in this half a year, everything has been calm, and Lu Tianji's spiritual strength has been smoothly improved from the sixth level of qi refining, all the way to the ninth level of perfection, and the sword quality grade has been improved to a seventh-grade treasure.

After the spiritual body cultivation reached the ninefold perfection of qi refining, Lu Tianji could begin to impact the foundation building realm.

However, breaking through the Great Realm requires a tribulation, and this is also the first tribulation that Lu Tianji has come to the Tianxuan Continent, so he is very cautious to choose a night full of thunderstorms, and use the thunderstorms in nature to cover up his movements.

Thundered!

In the midst of the raging storm, Lu Tianji urged his cultivation and caused a thunderstorm.

I saw a large area of black clouds gathered above the mound, and in an instant, thunder and lightning were like snakes, and thunder was like drums!

Soon, the first lightning tribulation slashed down, and when it slashed on Lu Tianji's sword body, the powerful voltage removed some impurities from the depths of the sword body, and Lu Tianji's sword body did not suffer any damage.

This...... Beyond the knowledge of Lu Tianji!

He couldn't help but be stunned, then opened the search bar on the attribute panel, entered the glazed immortal liquid, and immediately saw the details of the glazed immortal liquid.

[Glazed Immortal Liquid: Composed of 99 kinds of rare metals, it is a top-level liquid metal material, which can perfectly fit weapons of any material, making the grade of the weapon get a leap forward. In addition, due to the wide variety of metal compositions, the glazed fairy liquid can also be turned into a semiconductor material according to the different arrangements, which can resist a certain power of thunder.

Seeing this line of text, Lu Tianji was both relieved and shocked.

After he crossed over, he had only absorbed the glazed immortal liquid, and it was not difficult to guess what strange it was definitely related to the glazed immortal liquid.

It's just that what he never expected was that this glazed fairy liquid was actually a semiconductor material, and to put it simply, it was called a semiconductor if it could conduct electricity or not.

This material is very commonly used on the earth, but Lu Tianji is the first time to see it in another world, it seems that the natural laws of each world are different, and the way of using natural substances is also different, or rather, the end of science is theology, not all without roots.

After learning about the properties of the glazed immortal liquid, Lu Tianji's confidence in surviving the thunder tribulation increased greatly.

He immediately began to try to control the conductivity and non-conductivity of the sword body, and after a while, he mastered the trick.

Bang!

When the third thunder tribulation came down, the sword body was no longer conductive, and the current could not penetrate inside, and the Lu Tianji inside was unharmed.

When the powerful current hits the sword body, it is equivalent to a master of the foundation building realm swinging a hammer blow, directly hammering out the impurities in the depths of the sword body, making the quality of the sword body slowly improve.

An hour later.

The torrential rain weakened, the thunder faded away, and the thunderstorm ended.

Lu Tianji, who had survived the Thunder Tribulation, officially entered the Foundation Building Realm, and a stable and powerful aura spread out, and the quality of his sword body was refined by the Thunder Tribulation, and it was upgraded to an eight-grade treasure weapon!

[Congratulations on surviving the first thunder tribulation in the sword life, officially entering the foundation building realm, crossing the first threshold in the sword life, rewarding exercises: Ten thousand swords return to the sect, please continue to experience the wonderful sword life]

[Ten Thousand Swords Return to the Sect: This is an attack technique that belongs to the sword version, and it is no different from the human version after practice, but because the sword version and the sword fit perfectly, its power will be higher than that of the human version, once practiced, ten thousand swords surrender, ten thousand swords come to the court, and when attacking, it is like ten thousand swords returning to one]

Ha ha......!!

Seeing that the system actually rewarded [Ten Thousand Swords Returning to the Sect], Lu Tianji's mouth was about to laugh.

He had just entered the foundation building realm, and he was worried that he didn't have a powerful attack method, but he didn't expect the system to send it intimately.

After receiving the cultivation mantra taught by the system, Lu Tianji immediately couldn't wait to start cultivating the Ten Thousand Swords Returning Sect, and with his talent, it took two days to finally practice the Ten Thousand Swords Returning Sect.

"Hey, that's not right......"

Lu Tianji, who had cultivated ten thousand swords and returned to the sect, was in a very good mood, and he wanted to continue his cultivation, but he suddenly discovered a problem.

He found that he was absorbing the qi of ten thousand soldiers with full firepower, and he actually only absorbed the same amount as silk threads, which was absolutely abnormal, his cultivation had entered the foundation building realm, and the absorption speed should have become faster......

Glancing around, Lu Tianji immediately understood what the problem was.

It turned out that he had been practicing for half a year, and he hadn't noticed that the military qi around him had been absorbed by him.

At this moment, I saw that the weapons around me were all gray, as if they had been eroded and weathered by endless years, and it was estimated that a stronger gust of wind could blow these weapons into ashes.

These weapons have also been completely reduced to waste.

Lu Tianji also wanted to absorb the aura of the soldiers from them, which was naturally unlikely.

Moreover, Lu Tianji also noticed that the range of the weathering of the weapon was about a mile in radius, which happened to be the core area covered by the weapon cultivation array, and the degree of weathering continued to decrease a lot, and it seemed that the core location had become the hardest hit area.

Although Lu Tianji has a glazed immortal liquid that can hide the brilliance of the sword body, making its surface no different from an ordinary waste sword, but all the weapons within a radius of one mile are weathered, if there is only a waste sword with a complete body, it is strange not to arouse suspicion, so Lu Tianji thought about it again and again, and finally decided to move the place.

The first is to avoid attracting attention and continue to develop in a low-key manner.

Second, only by changing to a place with many weapons can we continue to quickly absorb the qi of ten thousand soldiers.

It happened to be night now, and there was no one in the mound, so Lu Tianji controlled the sword body to fly in the mound and began to look for a new foothold.

Taking this opportunity, Lu Tianji also observed the overall environment in the mound by the way, the mound of Wanqi Sect is different from the ordinary mound of soldiers, it is not built underground, but an open-air mound of arms, there is an active volcano rising from the ground in the center of the mound - Bingzuka Peak, the closer to the active volcano, the higher the temperature will be.

With Hyotsuka Peak as the center, a radius of 500 miles is the range of Hyozuka.

This is the Ten Thousand Instruments Sect has gone through hundreds of expansions over the past two thousand years before it has formed such a scale.

The core area of Bingzuka Peak is all placed with weapons at the level of the elders of the Ten Thousand Weapons Sect, while the periphery is more chaotic and casual.

With Lu Tianji's current strength, it was not enough to enter the core Hyotsuka Peak, so he found a position with more weapons on the periphery to settle down, and re-depicted the weapon cultivation array.

Airplanes!

However, just as Lu Tianji was depicting the cultivation array, a sword power suddenly swept over.
