This trip, whether it was Yu Fei, Yu Zhan, and Yu Feng, they all gained a lot, and Yu Zhan and Yu Feng hurriedly gathered the qualified members of the family, and they wanted to distribute all kinds of pills in their hands, so that the clansmen could improve their strength as much as possible.

Yu Fei put a lot of pills, golden tickets and other things at home, so that Yu Zhan and them could use them at any time in case of emergency, while he stayed in the room and concentrated on cultivating.

In the evening, news came from Zhuge Xin'er from the Dan Medicine Master General that a group of assassins tried to kidnap Zhuge Xin'er and wanted to snatch the Martial Spirit Ding, but they were killed by Zhuge Xin'er's guards.

Yu Fei raised his eyebrows slightly, he dared to do such a thing in the Imperial Sword City, and he was too bold, could it be that the person who wanted to snatch the Martial Soul Ding also knew the role of the Martial Soul Ding? Otherwise, he would not have done such a risky thing! If he dares to do such a thing, I am afraid that it must be a master from abroad. Whether it's a sword immortal or an enemy outside the borders, it's a threat that can't wait to be solved!

Although Yu Fei's strength has improved very quickly, it is still only a silver-level strength, and it is far from enough!

Although the Qinglong Martial Soul is a very powerful Divine Beast Martial Soul, but Yu Fei's current level, it can only exert the silver-level strength of the Qinglong Martial Soul, under normal circumstances, it is better not to use the Qinglong Martial Soul at will, because if the various abilities of the Qinglong Martial Soul are not exposed to the public, it can receive unexpected effects, but if it is performed openly and studied by many people, the current ability of the Qinglong Martial Soul will be suppressed.

Therefore, Yu Fei also has to fuse more martial souls, because cultivating the Heavenly Dao can fuse three martial souls, and every time he fuses a martial soul, Yu Fei's strength and cultivation speed will be greatly improved.

Of course, Yu Fei is very picky about martial souls, and when he is reborn, Yu Fei will not fuse some ordinary garbage martial souls! After having the Qinglong Martial Soul, Yu Fei has been preparing to find some special martial souls for a long time, but after having the Martial Soul Ding, Yu Fei has a new idea.

Use the Martial Soul Ding to refine a super powerful weapon martial soul!

At this time, a carrier pigeon landed on the shoulder of Yu Fei.

Yu Fei took out the letter on the pigeon's feet, was overjoyed after reading it, took a pen and wrote "received" on a white piece of paper, tied it to the pigeon's leg, and released the pigeon.

"I see, Chang Xin, you really impressed me!" Yu Fei was very happy in his heart!

Then, Yu Fei took out the Martial Spirit Ding, this transparent golden tripod, flashing with a golden luster, revealing a trace of mysterious aura.

This thing is a priceless treasure, I didn't expect it to appear in the auction house, so Yu Fei will be desperate to auction it, if he misses this martial spirit, Yu Fei will definitely regret his death.

Yu Fei stroked the Martial Soul Ding with his right hand, and penetrated a trace of soul power into the Martial Soul Ding.

The Martial Soul Ding suddenly shone brightly, forming an inexplicable connection with Yu Fei, the role of this Martial Spirit Ding, Yu Fei only knows a trace of skin, and he needs to study more.

One of the functions of the Martial Soul Ding, if ten of the same series of weapon martial souls are put into the martial soul Ding at the same time to refine, there is a certain probability that a more powerful martial soul of the same series can be refined, of course, it may also fail.

Yu Fei bought so many weapon martial souls in order to refine stronger weapon martial souls!

"The beast martial soul is already there, and what is most urgently needed now is a weapon martial soul that can face the enemy head-on!" Yu Fei thought for a while, he bought tens of thousands of weapon martial souls, these tens of thousands of weapon martial souls, I don't know if I can make a powerful weapon martial soul.

Each martial soul is divided into bronze, silver, gold, etc., which is the defining standard of the Blue Dragon Kingdom. What ordinary people don't know is that in fact, the growth of each martial soul is different, even if it is a very low-level martial soul, if the growth is strong enough, it is not impossible to kill a legendary-level martial artist after training!

At the same time, there are some special martial souls that have growth, not only the strength of the martial souls, but also the growth, such as the green dragon martial soul of Yu Fei!

Yu Fei divides the growth of the martial soul into five levels, including inferior, ordinary, good, excellent, excellent, super-god, the green dragon martial soul is undoubtedly a martial soul variety with super-god growth, and the improvement of the strength of the green dragon martial soul is not limited, but it is subject to the strength of the martial artist, and the strength of the green dragon martial soul itself is above the legendary martial soul, if it is not for the experience of the previous life, the green dragon will not be fused with the current Yu Fei.

Ordinary people don't know how to distinguish the growth of martial souls at all, only Yu Fei knows that just like human beings measuring soul power, the growth of martial souls can also be measured with purple water magic crystals, but the method of distinguishing them is different.

According to the degree of purple water scattering, you can determine the growth level of the weapon martial spirit!

For Yu Fei, the second fused martial soul will have a very far-reaching impact, even if you can't get a super god growth martial soul, you must at least get an excellent level, otherwise you will not only be sorry for the martial soul Ding bought at a high price, but also put yourself at a disadvantage in future wars!

Yu Fei took out ten sword-based martial soul stones and tested the level of these ten martial souls with purple water magic crystals.

Yu Fei quickly tested these ten martial spirits, six were inferior-level and four were ordinary-level, and Yu Fei couldn't help but be a little disappointed.

"Sure enough, it's still more difficult to pick out a higher growth spirit from ordinary martial souls!" Yu Fei thought a little depressed, it was too difficult to find a super god growth martial soul like the Qinglong Martial Soul.

Yu Fei put these ten martial souls into the Martial Soul Ding, and used his soul power to urge the Martial Soul Ding!

I saw that in an instant, the Martial Soul Ding kept shining up, emitting dazzling brilliance, and the halos of light flowed inside, which could be seen through the Golden Tripod Feather Fly, and after the ten lights and shadows kept rotating, they slowly merged together.

The result was a golden glow.

After about ten minutes, the light of the Martial Soul Ding slowly subsided, and a sword-type martial soul was like an elf, swimming non-stop at the bottom of the Martial Soul Ding's pot.

Yu Fei captured the martial spirit, attached it to an ordinary martial soul stone, and then checked the growth of the martial soul.

"The slightly complete purple water is already a good level! The Martial Soul Ding is really extraordinary! But a good level of martial soul is far from enough!" Yu Fei shook his head, in his eyes, he definitely couldn't look down on a good-level martial soul.

Yu Fei put this good-level martial soul aside, then picked up ten more martial soul stones and began to test them.

Ten sword martial souls, preferably a sword with sand, is a good level.

Yu Fei fused again and again.

The probability of refining failure is still quite small, almost dozens of times before one failure, but after refining more than two hundred times, the best one is an excellent level sword martial soul, and the rest are good level sword martial souls.

Yu Fei shook his head, it was still quite difficult to improve the level of these low-level martial souls.

However, there are still so many martial souls, Yu Fei will not give up refining, among the tens of thousands of sword-type martial souls, there are more than sixty sword-type martial souls of the excellent level, and more than two hundred of the good-level ones, which is still quite good.

For two whole days, Yu Fei continued to refine, again and again, fusing the inferior and ordinary martial souls into good ones, and then using the good-level martial souls to continue to fuse into excellent-level ones, and finally there were more than ninety excellent-level ones left, and then using these excellent sword-type martial souls to fuse the excellent-level ones.

The more you fuse, the greater the probability of failure, and finally succeeded in fusing eight excellent-level sword-type martial spirits.

Looking at these eight transcendent-level sword-type martial souls, Yu Fei was still a little unwilling, ten excellent-level sword-type martial souls could have a chance to fuse the super-god growth sword-type martial souls, and the probability of failure was very high. When fusing the superior-level sword martial soul, the probability of success is not even half, and if the super-god growth martial soul is fused, the probability of success is only one tenth.

The Dan Pharmacist Association, for the growth of His Royal Highness the Prince, did not hesitate and sent more than a billion gold coins.

After thinking about it, Yu Fei went to see Yu Zhan and Yu Feng, and asked Yu Zhan and Yu Feng to help him buy a large number of sword martial souls, as many as he wanted, and give them some remuneration for each sword martial soul he acquired.

Yu Fei gave a very generous remuneration, of course they did their best, and soon, Yu Zhan and Yu Feng went to various chambers of commerce to help Yu Fei acquire sword martial souls, and after spending hundreds of millions, Yu Fei bought a full 100,000 sword martial souls, and then used martial soul ding crazily.

As the number of fusions increased, Yu Fei found that the Martial Spirit Ding had also undergone some obvious changes, the yellow light of the Golden Tripod had turned into white light, and the periphery was platinum-gold.

Yu Fei's heart sank, he could feel that this Martial Soul Ding could absorb part of the power of the Martial Soul in the process of fusing the Martial Soul, and over time, the Martial Soul Ding would become more powerful.

For five days, Yu Fei has been concentrating on fusing the martial spirit.

Finally, more than seventy excellent-level weapon martial souls were fused.
