When Tian Yu had his first experience in refining weapons, the speed of refining the weapons was obviously accelerated. When the mining disciples held top-grade spiritual weapon-level mining tools, they all smiled from ear to ear.

You must know that there are not many top-grade spiritual stones in the entire Beiming Sea. If cultivators below the Nascent Soul stage can get a top-grade spiritual weapon, they will regard it as a treasure. But now these top-grade spiritual weapon-level mining tools can be seen everywhere. If they are

It would be strange if other forces saw it and ran over to snatch it.

But at this time, no one expected that the cultivation resources deep in the Thunder Prison would be secretly exploited by the Hua Yao Sect.

As time went by, the mineral veins on an island were almost exhausted. Then Tian Yu asked his disciples to build a copper pipe network. At first, the disciples were worried about being struck by lightning, but when the copper pipe network successfully guided the lightning underground

, everyone was safe and sound, which made the disciples feel at ease.

The instructors of the Spiritual Weapon Hall were not idle either. While they were refining the spiritual weapons, they were exchanging their refining experiences with Tian Yu. Soon they understood why the bottleneck could not be broken through.

It turns out that refining weapons is not as simple as refining weapons. The refining of ordinary spiritual weapons is the same as the first-level elixir. It involves extracting the essence from the materials. Only by striving for excellence can the essence of the materials be refined to what you want.

Only in this way can you refine the desired spiritual weapon.

As for the refining of second-level spiritual weapons, the creation of the spiritual weapons requires a different process. Only by attaching attribute conditions to the spiritual weapons can they be created.

For example, a pure top-grade spiritual weapon only reaches the extreme in toughness and spirituality, but this is still just a matter of refining and purifying the material itself.

The second-level spiritual weapon is also a treasure weapon. This requires that the spiritual weapon not only has the awakening of the spiritual weapon itself, but also adds other attributes. For example, the fire spirit sword can not only increase the fire attribute attack of the spiritual weapon, but also increase the wind after adding other attributes.

It has properties, metal properties, thunder properties, body skills and other functions, so the attack of the treasure weapon is stronger and more powerful.

The difficulty of refining a treasure lies not only in the purification of materials, but also requires the refiner to be able to carve runes and seals. The runes are the key to determining how many gems can be inlaid in the spiritual weapon. The seal is how many gems can be inlaid in the spiritual weapon.

The influencing factors are that if it is an ordinary weapon spirit, it can be inlaid with third-level gems at most, which will not add much to the properties of the spirit weapon.

In the past, the instructors of the Spiritual Weapon Hall believed that the key to refining treasures lies in materials. Without good materials, it is impossible to make good treasures. Then after Tian Yu used the same materials to refine treasures, this made all instructors

Start taking a serious look at your mistakes.

At the end of their experience, they finally discovered that runes and sigils were also their weaknesses, and it was impossible to create advanced runes and seals without advanced scrolls.

Although Tian Yu does not have scrolls with high-level runes and weapon seals, Hongye does. As a weapon spirit, she has her own god-level scrolls. She can easily pick up the high-level scrolls needed for the treasure. This is like a college student giving a primary school student

The questions are simply not too easy.

With the scroll given by Hong Ye, every instructor feels like they have obtained a treasure, and now they will not leave even if Tian Yu chases them away.

Next, while these instructors were learning advanced scrolls themselves, they were also teaching the disciples of the Spiritual Weapon Hall, which allowed the entire Spiritual Weapon Hall to grow rapidly.

Tian Yu is not here either. His main task is not to improve the weapon refining. He wants to go deep into the core of Thunder Prison to find out.

But before entering the core of Thunder Prison, he had a few things to do.

The first is to build a conductive electric armor. It seems that the conductive electric armor can remove the thunder falling from the void at any time. Although Hongye can help resist the thunder, her body is still a weapon. It may be enough if used by one person, but five

If individuals go to the core of the Thunder Prison together, it will obviously not be enough.

The mecha built by Tian Yu is divided into two parts. The outer layer is made of weapon defense-level material, and the inner layer is made of all-copper conductive material. This structure allows the person in the mecha to not be afraid of lightning damage, but also can effectively

To defend against the attacks of monsters from Thunder Prison.

There are five sets of this kind of mecha, and when it was successfully built, Hanhan and the others were very fond of it. This humanoid mecha is three meters high, so even Hanhan, who is as strong as an ox, can easily wear it.

Secondly, Tian Yu also made a treasure for each of Hanhan, Shadow, Qinglin, and Yash. Although the four treasures were not without gems, their power should not be underestimated.

Finally, to prevent the unexpected, Tian Yu asked Hongye to draw some teleportation symbols in advance. These teleportation symbols are much more powerful than the teleportation symbols on the market. Not only can they be teleported to fixed points, but they can also be teleported by multiple people at the same time, which is equivalent to everyone.

Carry a teleportation array with you. If you are in danger, you can teleport out from the core of the Thunder Prison at any time.

Everything was ready, all that was needed was the east wind. When the thunder in the void decreased a bit, Tian Yu and the others immediately put on their mechas and entered the core of the Thunder Prison.

You must know that the core of the Thunder Prison is not small, it is even very large, with a range of two thousand miles in the core area.

Hongye walked in front of Tian Yu, and she was not afraid even if the thunder fell. Although Tian Yu was wearing a mecha, his brows were furrowed because he had already been attacked by thunder three times after walking less than ten meters.

The four Hanhan people behind him were no better. Each of them had the courage to follow Tian Yu. If Tian Yu couldn't resist it, they would not hesitate to follow him and escape.

Fortunately, the five people's mechas were not damaged by the lightning strikes, and even emitted a unique silver light. This was the result of the lightning being absorbed, but the Hanhan didn't pay much attention to it.

At the core of the Thunder Prison, the material that Tian Yu and others saw most was magnet. This magnet is very strong, so it is very attractive to iron tools. If the materials of the mecha were not non-magnetic, at this time

They have been attracted and cannot move.

According to Tian Yu's calculations, the magnetic strength of these magnets is at least 10,000 times greater than that of rubidium magnets. Of course, the magnetic force of these magnets is not static, but continues to strengthen as the current changes.

Three months have passed, Tian Yu and the others have advanced five hundred miles, and what everyone sees is a dark mountain. The electric tubes all over this mountain are flashing, and the magnetic force it releases makes people feel uncomfortable all over.

"Does any of you know what it is?" Tian Yu looked at Hanhan and asked.

Both Hanhan and Shadow expressed their ignorance. In their bloodline memories, there was no record of such a sacred mountain, so they couldn't explain what was going on.

Yash on the side seemed to have thought of something and exclaimed: "Brother Tian, ​​I really want to see a similar mountain in an ancient book. This kind of mountain is called Ciyuan Mountain. They are originally products of the void, but I don't know why they fell.

It fell down, thus forming this amazing magnetic sacred mountain."

Tian Yu said thoughtfully: "As you said, if this is really a magnetite mountain that fell from the void, then it should be a star-level existence in the void. In my hometown, the stars in the sky are divided into planets, stars, and white dwarfs.

, red giant stars, neutron stars, magnetic stars, etc. It seems that this should be a magnetic star."

Tian Yu also liked to read knowledge about the universe before, but now he suddenly thought of a possibility, that is, the magnetic star was affected by some factors and finally fell into this different world.

Only this possibility will lead to the creation of spatial rifts and cause a large-scale thunder prison.

Just when Tian Yu was about to go to the Magnetite to find out what was going on, he suddenly felt his feet shaking. At first, he was the only one who felt that the island under his feet was moving, and then Hanhan and the others also felt something was wrong.

Because the island under our feet was shaking more and more violently, Hongyi quickly understood what he was really thinking and reminded loudly: "What we are under is not an island, but a giant turtle!"

When the others heard this, they were startled, and then quickly took off. When everyone flew flying knives a hundred meters high to check, they suddenly understood.

It turned out that they had all been looking at the magnetite in front of them, but they had ignored the giant turtle at their feet. This giant turtle was eight hundred meters long, and its back carried not only many stones, but also many corals and sea creatures.

shellfish.

At this time, it seemed to be frightened, so it wanted to move to the deep sea. However, its size was so large that it moved very slowly, so Hanhan didn't notice it at first.

Tian Yu was the first to notice that the giant turtle was moving. This was entirely because his soul power cultivation level was the highest among Hanhan, so his perception of danger became extremely sensitive.

Of course, this giant turtle did not harm Tian Yu and the others. It was thinking about how to dive into the deep sea, as if there was a greater danger coming.

But before the giant turtle dived into the deep sea, the magnetic element stone hundreds of miles away suddenly made a loud noise. Listening to the sound, Tian Yu had already guessed what it was, yes! The sound was from the thunder dragon.

The roar made.

At this time, no one knew why the thunder dragon roared. Tian Yu and others did not dare to go rashly, so they followed the giant turtle and planned to dive into the deep sea to avoid unknown risks.

However, before diving into the deep sea, Tian Yu felt that the mining disciples of the sect should be prepared to evacuate at any time. If Chiyu was affected, this would be a huge loss to the Chinese Medicine Sect. So he took out the sound transmission stone and asked Buick to observe it.

The core of the Thunder Prison changes. If the shadow of the Thunder Dragon appears, the disciples will be teleported away immediately.

After doing this, Tian Yu calmly paid attention to the appearance of the thunder dragon.

Half an hour later, the giant turtle finally moved to the deep sea. Before, he was able to surface only with the help of the rocks in the sea. Now it has broken away from the rocks, so it can dive into the deep sea at any time after floating on the surface.

Perhaps this giant turtle had the same idea as Tian Yu and others, and it also wanted to see what the dragon wanted to do.

After waiting for another half an hour, a black thunder dragon suddenly broke free from the shackles of Ciyuan Mountain and flew directly into the void. Then the thunder in the void seemed to be enraged and kept hitting the thunder dragon.

At this time, Hong Ye saw the clues and said: "This thunder dragon wants to use the power of thunder to overcome the catastrophe and ascend! It seems that it is destined to fail."

Tian Yu asked in confusion: "Hongye, you are so sure, what exactly is going on?"

Hongye smiled and said, "Brother Tian, ​​if I'm not wrong, this thunder dragon's cultivation has reached the peak of the Mahayana, and it can only be one step away from the tribulation. But if it wants to ascend directly, this chance is impossible. The thunder dragon is very strong.

, There is no doubt about this, but the period of transcending the tribulation is a hurdle. If you cannot successfully survive this period, even the thunder dragon will not be able to survive the tribulation with its powerful body."

"The reason is actually very simple, that is, its spiritual power may have reached the level of transcending tribulations, but its soul power is still at the peak of the Mahayana period. Such a mismatched state will definitely make it worse in the next ascension tribulation.

The soul is gone!"
