Chapter 337: Eight Hundred Demon Kings

The second watch, ask for recommendation tickets, monthly passes, rewards, etc., and there are two more in the evening.

......

Finally cultivating the Origin Immortal Divine Power to the Xiaocheng realm, Du Feiyun's strength directly increased several times, and he was one step closer to the Yuanying realm.

When he left the Hanging Mountain with Jiulong Ding, Du Xuanqing was still cultivating on the Hanging Mountain, and Xue Bing, Dire and the others were also in retreat in the medicine garden space.

In the meantime, he left the underground and drove the treasure flying boat back towards Baichuan Ling.

Now that Meng Meng is in retreat, unable to travel for him, this treasure flying boat is naturally obtained from the four real people of the Infinity Palace.

Although the speed of the Treasure Flying Boat is a little slower, but with the support of the best spirit stones, it can keep traveling, much slower than Mengmeng's speed, and it will take at least two months to rush back to the Liuyun Sect.

Yan Yunzi still didn't have any news, it is estimated that he is still in retreat, and Du Feiyun is also very helpless, so he has to return to the sect alone. The last of the remaining messengers was sent back to the Liuyun Sect by him, and he wanted to inquire about the situation in the door and ask if there were any powerhouses of the Wuji Hall who were coming to attack.

If the powerhouse of the Wuji Hall went to attack the Liuyun Sect now, he would also be beyond the reach of the whip, and it would take at least two months before he could rush back.

The powerhouses of the Ten Gates of the Immortal Dao, as well as the powerhouses of the five major empires of the Demon Clan, seemed to have heard the wind and rushed to the depths of the Sea of Blood to investigate the news of the Demon Emperor's treasure house. Du Feiyun was naturally amused by this, and secretly said that those people could only sacrifice a lot of time and manpower and material resources, but they were destined to return empty-handed.

His current goal is to rush back to the Liuyun Sect as soon as possible, guarding the sect is one thing, and the other is to retreat and cultivate with peace of mind, and impact the bottleneck of the Yuan Infant Realm.

Flying in the territory of the Extreme Blood Empire, Du Feiyun did not hesitate to consume spirit stones, and drove the flying boat to gallop with all his might, and once encountered a demon tribe on the way, so he simply landed in that tribe.

The strength of this tribe is much stronger than those tribes on the periphery of the Underworld Realm, and there are 100,000 demons in the entire tribe. The leader is a demon king of the ninth layer of innateness, and he is only one step away from condensing the silver pill. Moreover, in addition to this leader, there are also hundreds of demon kings of the innate realm.

When he met Du Feiyun, this tribe could only fall into bad luck, he found the leader of the demon king in the secret room with his spiritual sense, and captured the leader of the demon king with a little means, and then ordered hundreds of demon kings to gather together under the pretense of the leader's hand.

It only took a quarter of an hour for the hundreds of demon kings to follow in the footsteps of their leaders, and they were captured by Du Feiyun, and together with their leaders, they were all suppressed in the Tongtian Demon Tower.

Tongtian Demon Tower, a medium-grade treasure, is a magic weapon refined by the Shura Demon Emperor himself, and it is the embryo of a Horcrux, which has the potential to be upgraded to a Horcrux, and it contains many wonderful uses, so Du Feiyun has to spend some thought and intends to upgrade this treasure to a Horcrux little by little.

The few magic weapons on his body now have been cultivated for many years, and they are mellow and easy to control, and they all have the potential to be promoted to Horcruxes. Therefore, unless it is a Horcrux-level magic weapon, he will no longer sacrifice a treasure-level magic weapon.

The Tongtian Demon Tower was set to nine floors by the Shura Demon Emperor at that time, and later Du Feiyun cleared the level, and those levels were naturally gone, and now there are only two layers of space. The bottom layer is incomparably vast, just right for the survival and cultivation of the demons, and the upper layer is a cultivation cave, with all kinds of secret room treasures.

Du Feiyun released all the hundred demon kings he had captured in the space below, and gave them some pills every day, allowing them to cultivate in them to improve their strength.

Obviously, these demon kings are unwilling to be imprisoned, and they will break through the treasure of the Tongtian Demon Tower together. Changing to an ordinary treasure weapon, it is estimated that these hundred demon kings will collapse and collapse immediately with a single blow.

However, this Tongtian Demon Tower is a Horcrux embryo, and the materials are all materials for refining Horcruxes, and after returning to normal, the magic circle in it will operate automatically, and it will immediately suppress the hundred demon kings. ...,

Seeing that Du Feiyun was determined to refine his magic weapon and cultivate it into a horcrux in the future, the Shura Demon Emperor also moved his mind to help him and taught him a great magical power, which was the demon seed Dafa of the demon race.

This kind of demon seed Dafa is not a particularly mysterious supernatural power, it is just a supernatural power used by many demon lords and demon emperors to raise slaves, after Du Feiyun learned it, he used this supernatural power to immediately surrender the hundreds of demon kings, planting a brand of submission in the depths of their souls.

After being branded by the Demon Seed Dafa of surrender, unless Du Feiyun's body falls and his soul disappears into heaven and earth, these demon kings will always be extremely loyal to him and driven by his control.

After subduing these hundred demon kings, Du Feiyun issued them with a hundred top-grade spirit stones and a thousand spirit-grade pills every day, allowing them to cultivate and improve their strength with peace of mind, and to refine and strengthen the Tongtian Demon Tower.

After tasting the sweetness, Du Feiyun repeated his old tricks, recovering nine demon tribes in a row, and only plundered the demon kings and powerhouses among them, and he couldn't look down on those demon generals in the qi refining period.

At the end of the day, there were already a full eight hundred demon kings gathered in the Tongtian Demon Tower, and their strength ranged from the first layer of the innate to the ninth layer of the innate level, all of whom were branded by him to be planted with submission, and they cultivated loyally to cultivate and strengthen the Tongtian Demon Tower for him.

With the help of eight hundred demon kings, the power of the Tongtian Demon Tower immediately increased by twenty times, although it was only a medium-grade treasure weapon, its power was comparable to that of a top-grade treasure weapon. And Du Feiyun also plans to collect some more demon kings, but the Tongtian Demon Tower can only accommodate the strength of these eight hundred demon kings now, and if he wants to collect more demon kings, he must upgrade him to a high-grade treasure weapon.

What's more, using the Demon Seed Dafa to enslave the Demon King also requires strong mental cultivation to support. An ordinary peak cultivator of the Yuan Dan Realm, being able to enslave a hundred demon kings is the limit, and Du Feiyu being able to enslave eight hundred demon kings is very rebellious.

If you want to use the Demon Seed Dafa to enslave more Demon Kings, then you can only continue to improve your mental cultivation. If the strength reaches the Soul Refining Realm, such as the Shura Demon Emperor back then, the strength of the Divine Soul Realm is in a superb Horcrux, and he has raised a million demon kings to refine the formation for him, refine the elixir, and enhance the power of the magic weapon.

While hurrying on the road, Du Feiyun, under the guidance of the Shura Demon Emperor, began to upgrade the Tongtian Demon Tower. After all, eight hundred demon kings have been cultivating and growing in it for half a month, and the power of the Tongtian Demon Tower has reached its limit, and it can only be upgraded to a high-grade treasure weapon.

Originally, only a strong person with the strength of the Soul Refining Realm could refine a magic weapon at the treasure level, and Du Feiyun Yuan Dan Realm was only a strength, and he could not improve the level of the treasure weapon. However, now his mana is boundless, and he is not much different from an ordinary Yuan Infant Realm powerhouse, and he has the guidance and guidance of the Shura Demon Emperor, so he can barely upgrade the Tongtian Demon Tower.

While hurrying in the flying boat, Du Feiyun finally began to contact the refining weapon that he was not familiar with, and after preparing enough materials, he began to refine this Tongtian Demon Tower. The upgrade of the magic weapon requires very harsh conditions, and many times, the cost of upgrading a magic weapon to a level may far exceed the value after the upgrade, so unless it is a meaningful magic weapon, no one wants to do this kind of stupid thing.

For example, this Tongtian Demon Tower, upgrading from a medium-grade treasure weapon to a high-grade treasure weapon, needs to devour 4 medium-grade treasures, precious materials worth 30 million spirit stones, as well as Du Feiyun's ten days of hard work, and endless mana.

This kind of consumption has completely exceeded the value of a high-grade treasure, if it weren't for the great significance of this Heavenly Demon Tower, Du Feiyun would not want to do it. Fortunately, with the Shura Demon Emperor's words and deeds, and endless resources to support him, even he, who was not proficient in refining, finally upgraded the Tongtian Demon Tower to a high-grade treasure weapon after ten days.

Once the Tongtian Demon Tower became a high-grade treasure weapon, its power suddenly increased by nearly ten times, and it was immediately able to accommodate more demon kings to cultivate in it, and the Asura Shadow Great Array also changed. ...,

The Shadow of Shura Great Array is an extremely powerful formation of the Shura Dao, and it is a great magical power. The complete Shura Shadow Great Array, there will be eighteen Shura Phantoms, and each of them has the strength of the Yudan Realm, after the Great Array is launched, even the powerhouses of the Yuan Infant Realm can be strangled.

Now, the Tongtian Demon Tower has been upgraded to a high-grade treasure, and Du Feiyun also has enough mana to successfully condense the Shura Shadow Great Array, and all the eighteen Shura Phantoms have been revealed, all of which are the strength of the Silver Pill Realm.

If Du Feiyun launched the Shura Shadow Great Array, under the full siege of the eighteen Shura Phantoms, the Jindan Realm monks would be strangled immediately, and the Yuandan Realm powerhouses would also be severely damaged.

What Du Feiyun values more is that this Shura Shadow Array can be upgraded, a superb horcrux magic weapon of the Shura Demon Emperor back then, the Shura Shadow Array is composed of eighteen Yuan Shen Realm Shura Phantoms, and it can directly kill ordinary God Soul Realm powerhouses in seconds under full mobilization.

Therefore, Du Feiyun had already made up his mind to upgrade the Tongtian Demon Tower into a Horcrux in the future, and the Shura Shadow Great Array would also be cultivated to an extremely powerful level, and at that time, the Tongtian Demon Tower would be an extremely powerful magic weapon.

However, his mental cultivation has not improved now, so after the Tongtian Demon Tower is successfully upgraded, he can't expand the number of demon kings, so he has to wait until later. Immediately after that, he hit the idea on the head of the Zhenlong Eight Swords, this set of magic swords is still a medium-grade treasure weapon, and now it is not powerful enough many times, and it may be defeated when it encounters a high-grade treasure weapon.

Therefore, he concocted it in the same way, and it took half a month, five medium-grade treasures, and more than 30 million spirit stones to finally upgrade the Zhenlong Eight Swords to high-grade treasures. Du Feiyun also felt that anyway, the Demon Dragon Emperor was suppressed by him in the Sword Array, and he would definitely become the soul of the Eight Swords of the Zhenlong in the future, so he changed the name of this set of magic swords to the Demon Dragon Sword.

The name Zhenlong Eight Swords was also taken by himself, and no one knows the real name of this set of magic swords, so it is feasible to change it to the Demon Dragon Sword.

It's a pity that the gap between the top-grade treasure and the top-grade treasure can't be reasoned, even if he smashes down the resources of a billion spirit stones, if there is no corresponding opportunity and materials, it is impossible to upgrade to the best-grade treasure.

Therefore, the Tongtian Demon Tower and the Demon Dragon Sword have stopped at the top-grade treasure weapon for the time being, and if they want to upgrade to the best treasure weapon, it will take great opportunity and effort.

Fortunately, the top-grade treasure weapon is enough to deal with ordinary Yuan Dan Realm powerhouses, which is definitely more than enough.
