The large iron box held in the claws of the big metal bird is ten feet long, about fifty feet wide, and about three feet high.

From the outside, the iron box didn't seem to be huge, but the space inside was ridiculously large, at least three times larger than the fortress that Chu Tian had lived in for two days. The iron box was filled with hazy mist, and the top of the box was inlaid with fist-sized fluorite, which emitted a green light that illuminated the huge space.

At the bottom of the box, there were neatly arranged stone slabs, each three feet long and wide. After Chu Tian and others walked into the iron box, the stone slabs were just enough for them to sit cross-legged.

In addition to Tiesha and more than 500 others, Chu Tian also asked Duka to send in Tongchui from the opposite door and more than 700 men in his fortress.

After Tongchui entered the iron box, he immediately knelt in front of Chu Tian with more than 200 of his trusted men, and swore to submit to Chu Tian again. When the other hundreds of men in Tongchui's fortress saw Tongchui like this, and saw Tiesha and others who were watching him covetously, these men also knelt down one by one.

Regardless of whether they are truly convinced or not, at least Chu Tian has nominally become the leader of these more than a thousand men.

With the sound of a low mechanism, the iron box closed on all sides and shook slightly. It was obvious that the big bird flew into the sky with the iron box.

Chu Tian sat cross-legged on the stone slab, Iron Shark and Bronze Hammer sat beside him obediently, describing to Chu Tian their past experiences of participating in duels - sometimes, they fought against the enemy on the Blood Kill Castle's home ground; more often, they were just like today, being carried to other fighting arenas by these giant metal birds.

The iron boxes along the way were completely closed, and they couldn't tell where the Blood Killing Fort was or what the scene was like outside the Blood Killing Fort.

"Hmph, you bunch of idiots!" After hearing what the two said, Chu Jie jumped up, drew the Red Spirit Sword from his waist, and with a "swish" the sword cut fiercely on the smooth inner wall of the iron box.

With a humming sound, large defensive runes lit up on the inner wall of the iron box, and regular hexagonal barrier shields were ejected one after another, forming a half-foot thick halo on the inner wall.

With a loud 'crack', a circular magic circle with a diameter of about ten feet suddenly appeared on the top of the box, and a bowl-thick thunder roared down and hit Chu Jie's head heavily. Chu Jie groaned, and his hair was smashed to pieces. The lightning ignited his hair, and most of his hair was burned in an instant, revealing his white scalp.

Just as the lightning was about to pierce through Chu Jie's body and hit his internal organs, a ghost howl was heard, and the "Ten Thousand Ghosts Paying Homage to the Emperor" spewed out dark wind and ghost energy from Chu Jie's body. Black dark winds swirled rapidly, absorbing 70% to 80% of the raging lightning, annihilating 10% to 20%, and finally repelling less than half of the lightning, turning it into countless extremely thin electric lights that scattered in all directions.

Iron Shark and Copper Hammer didn't have time to dodge and were hit by several splashes of lightning. The two of them screamed "Ugh Ugh Ugh", rolled their eyes, and fell to the ground twitching. Soon, the pungent smell of burnt flesh emanated from their bodies.

Chu Tian hurriedly slapped the two men's chest with his palm, and the Thunder Seal was activated. The thunder force that rushed into the two men's bodies was absorbed by Chu Tian with one palm. He also quickly took out two healing pills that he had made out of boredom when he was climbing the giant iron chain under the Demon Suppression Palace, and quickly stuffed them into the two men's mouths.

Tiesha and Tongchui exhaled heavily a puff of black smoke. The healing pills that Chu Tian stuffed into their mouths quickly repaired their muscles that were damaged by the thunder force. Waves of powerful medicinal power washed over their bodies. The two of them suddenly felt inspired and sat cross-legged, silently practicing their main skills to start a breakthrough.

Chu Tian used the fine spiritual medicines from Dayi Qianjun, Daye Pojun, Yin Youyou, You Qianxun, Shui Bingyu and others to refine the elixir. These medicinal materials themselves were extremely potent, and they became even more potent after being refined into elixirs by Chu Tian. In addition, the elixir furnace had been warmed for several months, and it also absorbed some of the mixed auras emitted by the inner elixir of the deep-sea giant monster when it was purified. The medicinal power of the elixir was a bit amazing.

At least Iron Shark and Copper Hammer had never taken such a "magic pill" in their lives. Their faces suddenly turned purple and red due to the overly powerful power of the pill, and even a trace of foul air kept spewing out of their pores.

Iron Shark and Copper Hammer continuously heard the sound of a bowstring breaking. It was the powerful Dan force, led by their own Wu Yuan, that broke through the blocked meridians and acupoints, and broke through the periosteum barrier between the tendons and bones...

Suddenly, several farts were heard, and Iron Shark and Copper Hammer spit out sticky black blood. They suddenly jumped up, and their aura suddenly increased by more than ten times. They actually broke through from the Flesh Refining Realm, the Tendon Refining Realm, and the Bone Refining Realm, and directly broke through to the Blood Refining Realm!

Although they did not have any advanced martial arts, they simply relied on powerful medicinal power to force a breakthrough. They were weaker than those who had advanced martial arts and broke through naturally, but after breaking through to the Blood Refining Realm, they were able to become top-ranked masters in the entire Blood Killing Castle.

“Brother!” Tiesha and Tongchui suddenly knelt on the ground and kowtowed to Chu Tian: “Brother, from now on, if you let us die, and we say no, we will let the brothers poke 360 ​​transparent holes in our bodies!”

Iron Shark and Bronze Hammer once again expressed their loyalty to Chu Tian with the simplest and most brutal words.

With their backgrounds and experiences, they had never heard of such a powerful elixir. Chu Tian could easily take out such an elixir to heal their injuries. The two were shocked, but also full of gratitude to Chu Tian.

"Why do I want you to die?" Chu Tian shook his head and smiled, "Everyone, we are all family from now on, just get along well."

The group of big men under Iron Shark and Bronze Hammer saw that Iron Shark and Bronze Hammer had inexplicably obtained such benefits, and their eyes were filled with envy and jealousy. When they looked at Chu Tian, ​​there was awe, but also respect and closeness. Of course, there were also those who didn't know the life and death, mainly the people in Bronze Hammer's fortress, and when they looked at Chu Tian, ​​it was as if they were looking at a fat sheep.

The iron box shook heavily, and with a loud bang, it fell to the ground.

The four sides of the iron box opened at the same time, and daylight shone in.

Chu Tian was the first to walk out of the iron box. He looked around, and his eyes suddenly froze. He stared blankly ahead, wondering if his eyeballs were broken. Why did he see such things?

This is a grassland with abundant grass and water. About ten miles behind Chu Tian and others, there is a bright river that meanders like a ribbon.

Right in front of Chu Tian, ​​there was a small hill several miles in radius, about seventy or eighty feet high, surrounded by a cedar forest. On the top of the gentle slope of the hill, stood a castle about a hundred feet square, shining with a faint metallic luster.

The castle wall was about 20 feet high, and figures could be seen walking back and forth on top of the wall.

What made Chu Tian almost doubt whether there was something wrong with his eyes was the equipment on these figures.

He subconsciously looked back at Chu Jie and others who were coming out of the iron box. Yes, it seemed that he had not come to the wrong place!
