After Ye Fan's strength increased greatly, his speed also increased a lot, aiming at the direction where the dungeon was located, and he was constantly hurrying, and his location was about ten thousand miles away from the dungeon.

If it was in the outside world, Ye Fan would be in a hurry with all his might, and it would only take five days to arrive, and he would be able to catch up with a distance of two thousand miles every day, but this is the killing capital, and it is full of crises, even Ye Fan does not dare to trespass unscrupulously, and the speed is naturally reduced a lot.

Even so, after ten days, Ye Fan also successfully arrived at the underground palace, which can be said to be full of dangers along the way, not only the fierce beasts from the killing capital, but also the extremely harsh natural environment that can even kill the emperor-level powerhouses, as well as the endless emergence of strong people.

In the ten days, Ye Fan killed no less than twenty strong people, including demons, creatures from the Star World, and even human beings.

To be able to enter the Killing Capital, everyone has extraordinary strength, and the weakest combat power is also around the peak of the Emperor Rank, and even many people's combat power is not much better than Ye Fan.

When encountering people from the demon clan, Ye Fan will naturally not be polite and kill them all, and for the creatures of the star world, as long as the other party does not have bad intentions, Ye Fan will not take the initiative to provoke, but if the other party takes the initiative to take action, Ye Fan will naturally not show mercy.

In addition to those strong people who were killed by Ye Fan, there were a few who escaped in Ye Fan's hands, most of these strong people had extremely strong life-saving abilities, or powerful treasures, enough to escape in Ye Fan's hands, and a few were strong and bent on escaping, even Ye Fan could not be killed.

Among them, there is one of the most powerful opponents, the Moon Demon clan from the demon clan, whose combat effectiveness is not much better than Ye Fan, and after a short fight, both sides felt that the other party was not easy to mess with, and they tacitly chose to stop, because if they continue to fight, it is likely to be a lose-lose situation.

The Moon Demon Clan is one of the top three powerful races among the Demon Clan, among which not only are there strong people, but also geniuses emerge in an endless stream, and their overall strength is even much stronger than that of the Heaven and Earth Fighting Martial Arts.

The genius of the Moon Demon Clan is himself the existence of the peak of the Emperor Rank, and he is only one step away from the half-step Venerable Rank, and his combat power is even more powerful, which makes Ye Fan a little helpless, and as a genius of the Moon Demon Clan, he naturally will not lack life-saving things, after weighing the pros and cons, Ye Fan also gave up his plan to fight to the death with the other party.

And except for the genius of the Moon Demon Clan, there were a few other powerhouses who were only slightly inferior to Ye Fan, although they couldn't fight against Ye Fan, but they were enough to escape easily.

After the continuous battle, Ye Fan also had to admire the attraction of this killing capital, which gathered a large number of geniuses from the Star World and the Demon Race, and Ye Fan believed that there must be more powerful among these geniuses, enough to defeat him, so Ye Fan did not dare to have any carelessness in his heart.

After killing more than twenty enemies, Ye Fan also successfully obtained more than twenty Yuan Dan, most of which were at the peak of the Emperor Rank, and six were at the half-step Zun Rank.

In addition to these gains, Ye Fan also obtained a large amount of storage equipment, and most of the powerhouses who were able to enter here had their own backgrounds, and a large part of their belongings were placed in their own storage equipment.

These more than twenty enemies not only provided Ye Fan with a large amount of Yuan Dan, but also had huge wealth, but what made Ye Fan more regrettable was that the wealth possessed by those demons was useless to Ye Fan.

The currency used by the demons is the unique magic crystal of the demon world, this thing is useless in the star world at all, there are many materials and medicinal materials, weapons, etc., which are unique to the demon world, and only the demons can use it, for Ye Fan, in addition to collecting, there is no other use.

However, the few Star World creatures who attacked Ye Fan had treasures that Ye Fan could use, and after counting, there were millions of spirit crystals alone, and there were even high-grade spirit crystals among them.

You must know that the top-grade spirit crystals not only contain a huge amount of spiritual energy, but at the same time, these spiritual qi are also very pure, which can be directly absorbed by cultivators to restore their fighting energy, or to increase the speed of cultivation, while the middle-grade and lower-grade spirit crystals do not have this effect.

It's a pity that the number of these high-grade spirit crystals is relatively small, and Ye Fan can only use them carefully.

In addition to the spirit crystal, there are also a lot of materials and treasures, pills, etc., which are also a considerable wealth for Ye Fan.

What made Ye Fan happiest was the Yuan Dan from the hands of the more than twenty strong men, these strong men had more or less killed some fierce beasts or other strong people, and the Yuan Dan accumulated in their hands was even more than Ye Fan, after all, they had entered the Killing Capital for a longer time than Ye Fan, and they were not in a hurry like Ye Fan.

In the end, the Yuan Dan in Ye Fan's hands can be said to have multiplied many times, just the Yuan Dan of the half-step Venerable Rank, there are thirty or forty pieces, most of which are from the hands of the six half-step Venerable Rank powerhouses who died in his hands.

And the Yuan Dan at the peak of the emperor rank, the number is even more, there are more than two hundred, and the number of lower-level Yuan Dan is even more, but those Yuan Dan Ye Fan no longer cares.

With a large number of Yuan Dan, Ye Fan will naturally not be stingy, with the support of a large number of Yuan Dan, Tianhuo has successfully broken through to the half-step Venerable Rank, and at this time, Tianhuo's combat power is no longer below Ye Fan at all.

And Ye Fan only used Yuan Dan to break through the Emperor Rank level, and then temporarily stopped refining Yuan Dan.

Although there will be no sequelae of using Yuan Dan to improve strength, Ye Fan does not want to rely on Yuan Dan to improve all the time, the strength of cultivators is reflected in several aspects, one is cultivation, but martial arts, and in addition, combat experience.

Ye Fan didn't want to let his other two aspects be pulled down because of Yuan Dan's rapid promotion, so after successfully breaking through to the emperor level, Ye Fan was ready to precipitate for a period of time, and during this period of time, he would improve his ability in the other two aspects, and the best way to improve his ability in these two aspects was undoubtedly to fight.

Ten days and dozens of battles brought Ye Fan not only wealth and the harvest of Yuan Dan, but also the improvement of his own combat effectiveness.

Ye Fan stood on the top of a mountain, looking into the distance, there was a huge palace there, looking at it from afar, this palace was like a prehistoric beast, exuding the atmosphere of desolation and antiquity, and people's spirits were greatly suppressed.

The area of the palace is huge, but Ye Fan understands that the most precious place of this palace is not on the ground, but under the palace, the even more huge underground palace.
