That's right, all real spiritual weapons are engraved with formation runes with different functions and powers.

Some formation runes can increase the weight of the spirit weapon, some can enhance the sharpness of the spirit weapon, and some can increase the flight speed of the spirit weapon.

And the formation runes of the same ability also have a difference in power.

In the space ring of the black man in the foundation building period, there were some formation runes used to refine spiritual weapons, so Lin Yuan only needed to reforge the spiritual weapons he had refined before and add the formation runes to increase its power and turn it into a real spiritual weapon.

Thinking of this, Lin Yuan immediately walked out of the cave, stepped on the silver frisbee of the black man in the foundation building period, turned into a silver streamer, and went straight to the volcano not far away.

On the way there, Lin Yuan kept scanning the surrounding mountains, trying to find the traces of the three flat-headed brothers.

Those three guys haven't come back yet, and Lin Yuan is inevitably a little worried.

But now, he had other things to attend to, and he didn't have time to find those three guys, so he had to wait until he had time to find them.

As for the Ten Thousand Demon Valley, Lin Yuan would naturally look for it.

It's just that now is not the time at the same time.

After all, it is said that in the Valley of Ten Thousand Demons, there are many powerful demon clans.

He had to improve the strength of himself and the herd before he could rest assured that he would go to the Valley of Ten Thousand Demons.

......

After advancing to the foundation building period, Lin Yuan's flight speed far exceeded before.

A moment later, he was on the volcano.

In the process, he didn't find the three flat-headed brothers.

Standing next to the crater, Lin Yuan waved his hand, and a black forging platform appeared out of thin air in front of him.

This forging platform is made by him using the high-quality ore on that mine as the main raw material and fusing a variety of rare ores, which is extremely hard and is specially used to create spiritual weapons.

After that, he immediately took out the green flying sword, silver spear, transparent flying needle, black and red shield, blue boat, and even the set of broken black armor on his body, as well as the broken silver armor of the black man in the foundation building period and other spiritual weapons, and immediately began to reforge it according to the refining method of the Jinyang clan.

The materials of his several spiritual weapons are very good, and they can be used to create medium-grade spiritual weapons, and even some of these materials can be used to create high-grade spiritual weapons, so after being reforged, they will inevitably become medium-grade spiritual weapons with amazing power.

In this reforging, Lin Yuan not only added formation runes to these pieces, but also referred to the refining classics of the Jinyang clan and added some rare materials, which made the quality of the spirit weapon to a higher level.

The method of forging a real medium-grade spiritual weapon is very complicated, and the process is very cumbersome and time-consuming.

Therefore, it wasn't until the early morning of the next day that Lin Yuan re-forged those few spiritual weapons.

After being reforged, there seemed to be an extra layer of luster on those medium-grade spiritual weapons, which were very dazzling, and at a glance, they knew that they were not ordinary.

In fact, today's green flying sword has become sharper, transparent flying needles and silver spears have become more penetrating, black and red shields have become stronger, blue flying boats have become lighter and faster, and the silver-black armor formed by the fusion of black armor and silver armor has become harder.

Of course, this is only a part of the changes in those spiritual weapons, in addition, their abilities in other aspects have also been strengthened to a certain extent.

In terms of overall quality, his flying sword, flying needle, and silver spear were even more powerful than the silver of the black people in the foundation building period.

And the silver-black armor he reforged was even more powerful than the silver armor used by the blacks in the foundation building period.

As for the black-red shield, it was much more powerful than his silver-black armor after reforging, and ordinary medium-grade spiritual weapons were absolutely impossible to break, and even, even in the face of high-grade spiritual weapons, they might be able to resist for a moment.

And the blue flying boat, after being reforged, was faster than the silver disc of the black man in the foundation period.

With these real mid-grade spiritual weapons, Lin Yuan's strength has improved a lot.

After reforging his spiritual weapon, Lin Yuan took out some ore and began to forge spiritual weapons and armor for the cattle on the mountain.

Originally, he wanted to take back all the weapons and equipment on the herd and forge them all over again.

But when he left, there were many bison that weren't on the mountain, and he didn't have time to wait for those guys to come back.

Fortunately, there was that mine, and he had so much ore on him that it was more than enough to create some new spiritual weapons for the herd, and even more convenient, so he went directly to this volcano.

However, he would not directly distribute these newly created low-grade spirit weapons to all bison.

Instead, these real low-grade spiritual weapons will be handed over to Xiaohua to deal with, and only the bison that performs well will be eligible to get this more powerful spiritual weapon!

The process of building a low-grade spiritual weapon was much simpler than that of a medium-grade spiritual weapon, so it only took one day and one night for Lin Yuan to create a large number of weapons and shields for the bison on the mountain.

These weapons and shields were all real low-grade spiritual weapons, much more powerful than those weapons he had built at random before.

Even, it was even more powerful than the lower grade spirit weapon spear he gave to the Monkey King.

If these spiritual weapons are spoken, even the Jinyang clan will probably be greedy.

After all, although the Jinyang clan had superb refining skills, they did not have as many precious ores as Lin Yuan, so the spiritual weapons refined by their clan were not only limited in quantity, but also inferior in quality to those refined by Lin Yuan.

After building the spirit weapon, Lin Yuan got on the blue flying boat, turned into a faster blue streamer, and went straight to the spirit mountain.

After going back, Lin Yuan first took out some real low-grade spiritual weapons and handed them to Xiaohua, and then went to the medicine garden in the back mountain and took out a large number of spiritual flowers and spiritual grass.

Originally, Lin Yuan didn't know the names and medicinal effects of those spirit flowers and spirit grasses.

However, in the alchemy books of the Jinyang clan, there are many names of medicinal materials, including most of the spiritual flowers and spiritual grasses on the mountain behind him.

Not enough, only a small part of these Spirit Flowers and Spiritual Grasses are used to refine the Juyuan Pill, and more Spirit Flowers and Spiritual Grasses are used to refine the Gathering Qi Pill and the Zhuji Dan.

Although these two pills were of little use to Lin Yuan, he had to try to refine some.

On the one hand, these two pills can improve the overall strength of the herd, and on the other hand, they can also allow Lin Yuan to accumulate experience and improve his alchemy attainments, laying the foundation for him to refine Juyuan Dan in the future.

So in the following few days, Lin Yuan was in the cave mansion, while bathing in the mysterious white pool water, while swallowing Juyuan Dan and snake gall bladder, plus spirit stones, and cultivating hard, at the same time, he also took time to refine the Qi Gathering Pill and Zhuji Dan to improve his alchemy attainments, and even he would study the Jinyang clan's method of cultivating wind spells......
