Since they had made an agreement with these people from the White Marks Mercenary Organization, they had to prepare in advance, after all, it was a Black Iron Warrior of the Six-Rank Realm.

Even if he is seriously injured, but the emaciated camel is bigger than the horse, who knows what kind of hole cards he has. Don't kill them at that time, but lose their lives for it.

The first mission released by the Fire Dragon Mercenary Organization lasted for two weeks, and it was not difficult for them to gather enough points in these two weeks, and with so many days of hunting, they were now familiar with it.

The hunt for the wanted criminals is carried out cautiously and intensively.

Time flew by, and the two-week mission ended in a battle with everyone. The three leaders once again summoned everyone to the hall and quickly announced the results of the first mission.

In this mission, more than 20 people were eliminated, and most of these people had gloomy faces, so they could only return to the Fire Dragon Mercenary Organization under the arrangement of these three leaders.

Of course, there are some people who feel lucky, although it sounds a little bad to be eliminated and returned, but they are at least alive and leaving this terrible place.

There are also those who are buried forever in the Killing City, becoming one of the many ghosts of the Killing City.

The eliminated people, plus the new mercenaries who were killed, added up to a third of the total, and this was only the first mission, and the dangers they would face in the future would definitely be more.

Looking at the new mercenaries below who were either gloomy, secretly happy, expressionless, or solemn, the three team leaders just sighed softly, and then said nothing more.

Give everyone three days to reprieve and this second mission will be released in three days.

After the three leaders left, Su Han and the others each returned to their rooms, since they had three days of reprieve time, they just took advantage of it, and the time to get better with a few people from the White Mark Mercenary Group happened to be within these three days.

Back in the room, Su Han took a deep breath, he sat cross-legged and summoned the source stone crystal in the rooftop space.

During these two weeks, he didn't use the source stone crystal very often, which was also to reduce the damage of the source stone crystal.

"This source stone crystal must be used in the most critical place!" Su Han's eyes flashed with light, and he took out a few pieces of blood spirit crystals to replenish the energy in this source stone crystal again.

When the saturation information came from the source stone crystal again, Su Han grabbed a few pieces of blood spirit crystals and began to cultivate by himself.

His spiritual power was fused into the blood spirit crystal, quickly extracting the blood qi energy in it and inhaling it into his abdomen, which was the first time that Su Han absorbed the energy in the blood spirit crystal.

These blood energy energies are really powerful!

Su Han's brows furrowed slightly, the energy in these blood qi energies was even more violent than the core of black iron.

Su Han endured the tearing pain and sucked these energies into his black iron heart one by one.

In his senses, the four lines on the Black Iron Heart quickly formed a vortex, swallowing mist-like blood qi energy.

"Huh?" Suddenly, Su Han sighed softly, and he spread his spiritual power so that he could see the scene in his body more clearly.

In his observation, most of the blood energy was swallowed up by the heart of black iron, and the blood energy of one part entered the rooftop space, and he looked again, those blood energy was divided into two strands in the rooftop space.

One of them was swallowed up by the small fire, but the remaining one was absorbed by the gluttonous white bone knife.

Slightly surprised, Su Han didn't interfere and let it be.

The blood spirit crystals turned into powder in Su Han's hands one by one, and Su Han was not stingy with his own cultivation.

Time passed minute by minute, and on Su Han's black iron heart, the four lines exuded a brilliant luster, especially next to the fourth line, a small fork had been divided, and the fifth line corresponded to the five-grade realm, which was derived from this fourth line.

Now this branch fork is still small and in a young state, when this fork is completely transformed into the fifth line, it is also the time when Su Han breaks through to the realm of five grades.

The agreed time with the people of the White Stain Mercenary Organization was the last of the three days, and the first two days became the days of their penance.

Each city chooses a different address, but it will choose a place with abundant energy, and this Killing City, as one of the top cities in the Canglan Star Domain, the address chosen when building the city is naturally not an ordinary place.

The energy in the air here is much stronger than that of Momiji City.

In this Killing City, even the speed of their cultivation was one or two times faster than usual.

In the past two days, Su Han has been in a closed penance, devouring dozens of blood spirit crystals, although he has not entered the realm of the fifth grade, but his harvest is also very much.

Two days later, Su Han came out of the room, and Ye Zhongsong, Wang Kexin and Liu Han also walked out one after another.

Looking at these three people, the momentum of these three people has changed more or less, especially Wang Kexin, who has changed the most.

"Congratulations!" Su Han smiled at Wang Kexin.

Among the four of them, Wang Kexin was the first to break through to the realm of the third grade, as for Liu Han and Ye Zhongsong, although the two of them have not yet broken through to the realm of the fourth grade, they are not far behind.

"Thank you." A shallow smile appeared at the corner of Wang Kexin's mouth, "The energy in this killing city is really abundant. ”

"Indeed, if we stay here for a while, we will be able to break through to the realm of the third grade." Liu Han hid the gloomy look in his eyes and said with some bitterness.

Before entering the Fire Dragon Mercenary Organization, he was already at the realm of the second grade, but after a few months, he had not yet broken through to the realm of the third grade.

In the eyes of others, this is a normal thing, but the pressure on him is even greater when everyone around him catches up with or overtakes him at a rapid pace.

The higher the realm, the higher the requirements for spiritual power.

Wang Kexin, as a spiritual mind master, her strong spiritual power has helped her to advance her cultivation to a large extent.

Just like Su Han, although Su Han had a lot of adventures in that testing ground, his extraordinary spiritual knowledge also played a considerable role.

Otherwise, he would not have broken through to the realm of the fourth rank in this short period of time.

This also shows the importance of "The Great Soul Devouring Secret Technique" even more.

"It's almost time, it's time to go and join them, this hunt is not trivial, you must be careful and careful!" Su Han reminded them repeatedly, and then led them to the agreed place.

The security base of the Killing City is built on the outermost part of the city, and the scale of the security base is also quite large, all of which are surrounded by special alloys, looking like a fierce beast crawling on the ground, exuding a stormy momentum.

Even before he got close to this safe base, that strong killing blood swept over the sky.

It's not like the first day when they first came, this time, Wang Kexin and the others only frowned slightly, and there was not much discomfort.

As for Su Han, the expression on his face was even more flat

"Damn, those guys won't fool us, it's been so long, why haven't we arrived yet." Sun Li said with some complaints, he was originally prejudiced against Su Han and the others, if it weren't for Wang Yan, he would have wanted to plunder these people last time.

"Brother Wang, do we really want to cooperate with them, there are not many geniuses in our mercenary group, tell us the reason, I believe there will be many people who are willing to cooperate with us, why cooperate with an outsider?" Lou Xiao questioned.

"Don't worry!" Wang Yan closed his eyes and recuperated and stopped talking.

Knock knock knock!

Just as Wang Yan's brows furrowed, and the impatience on Sun Li and Lou Xiao's faces became heavier and heavier, there was a heavy sound of footsteps coming from the wooden staircase, and four people walked out of the room.

"Sorry, I'm late." Su Han said apologetically.

"I thought you guys were scared and didn't dare to come!" Sun Li sneered.

"How could we be afraid! If you agree on something, you won't miss it. Ye Zhongsong said.

"Alright, it's good to be here." Wang Yan's brows furrowed, and without any complaints, he took out a scroll of drawings from the side of the table wall, on which a garden villa was drawn.

"This is where Yu Daoqing lives." Wang Yan stretched out his hand and pointed to the center of the map, "This area is this guy's bedroom, no accident, we will hunt here." ”

The Yu Daoqing that Wang Yan said was naturally the target of their action this time.

"Tsk, this guy is really rich, and he actually has a manor in this safe base." Liu Han sighed.

The security base of this killing city was not like the security base that Su Han had encountered before, this killing base was almost a huge city, from the residential houses on the ground floor to the administrative office on the upper level.

This security base alone is half the size of Momiji City.

And to be able to have a private estate in the safe base of this killing city, this person's wealth or power can be imagined.

"There is a manor, and naturally there is also the presence of guards. However, this Yu Daoqing is extremely confident in his own strength, and even if his combat power is declining now, he has not hired many guards. Wang Yan said, "This point just cheapens us." ”

"We just need it"
