Castle of Black Iron

Besides the fruit of brilliance, Zhang Tie had another great achievement——a fruit of bloodline, which increased Zhang Tie's empty bloodline energy to 34,150 points. As a result, Zhang Tie could activate more bloodlines at the critical moment.

As for how many bloodline energy points could a fruit of bloodline bring him, Zhang Tie didn't figure it out until now. After all, it depended on the enemy, the difference in the battle strength between Zhang Tie and his enemy and the difficulty in killing his enemy. As for the details, perhaps only the small tree knew.

For instance, the death of Han Zhengfang brought Zhang Tie 15,687 bloodline energy points. That was really a fierce battle. However, this time, after killing three semi-sage level knights, he only got 34,150 bloodline energy points. As for the reason, Zhang Tie didn't feel like studying it. No matter what, he was already satisfied as long as he had a fruit of bloodline.

Besides, the small tree also continued to bear fruits of redemption like before. After taking all the fruits, Zhang Tie's overall strength increased again.

However, when Zhang Tie was so thrilled that he thought he could completely recover his battle strength, he finally discovered the sequela of the combat between him and Versatile Demon Emperor...

...

After taking the fruits, Zhang Tie's spiritual energy surged and reached a new level. However, the battle qi in his qi sea was still empty. At this moment, a whim occurred to Zhang Tie——filling the void above qi sea with his own spiritual energy.

To put it simply, with Zhang Tie's control, the enormous spiritual energy in his mind sea would rush into the grey fog in the void above his qi sea. He intended to fill the grey fog with sufficient spiritual energy so that it would not absorb his battle qi any more.

According to Zhang Tie's knowledge, now that the grey fog in his mind sea and in his qi sea were both left by the Breaking Formation Immortal Thunder, he could clean up the two balls of energy by the same method. The grey fog in his mind sea had already disappeared after eating enough spiritual energy; Zhang Tie thought that he could clean up the same grey fog in his qi sea in the same way.

Although there was no spiritual energy in his qi sea, Zhang Tie could transfer his own spiritual energy into his qi sea.

Zhang Tie's conjecture was correct.

After absorbing enough spiritual energy, the remaining grey fog in Zhang Tie's qi sea gradually turned white; then, the white fog gradually faded away in the qi sea.

Zhang Tie thought that he had already completely recovered. He only needed to wait for the battle qi to show up in his qi sea and gradually become as much as before. Unexpectedly, after driving the grey fog away, the battle qi in his qi sea still remained at a very low level...

...

On April 4th, the 3586th year of Emperor NvWa's Calendar...

Under the Manjusaka karma fruit tree, Zhang Tie was sitting there in a dignified way for silent cultivation, legs crossed. From the start, Heller had been watching him with a concern...

In the beginning, Zhang Tie's face and body looked normal; however, after sitting there for half an hour, Zhang Tie's face gradually turned redder as he continued to tremble all over.

One hour later, Zhang Tie's face suddenly turned pale as he spurted out blood, which fell onto the cyan stone stairs leading to the sacrificial altar under the small tree...

"Castle Lord..."

After hearing Heller's words, Zhang Tie finally opened his eyes. Panting heavily, he slightly shook his head towards Heller, implying that he was fine. After that, he wiped the bloodstains off his mouth corners and watched the sacrificial altar in front of him.

The scarlet blood was very eye-catching. Zhang Tie felt like being torn apart by five vehicles when he tried to light his chakras.

Zhang Tie had adapted to light his own chakra by Purgatory Samsama Method. Whereas, he had not imagined that such a simple way could become a tough mission that would barely be completed.

There was only one reason for that——insufficient battle qi!

Without the propulsion of powerful battle qi, even if Zhang Tie had great spiritual energy, he could not light even a bit of chakra. Because the process of lighting one's chakra was the most important cultivation process of knights. Besides spiritual energy, the one factor which could reflect the knight's realm and battle strength was battle qi. Therefore, without the coordination of the most important battle qi, knights couldn't continue the most important cultivation process anymore.

Previously, Zhang Tie didn't feel that battle qi could be so important in this process. Now he realized it. Facing this result, Zhang Tie didn't know whether to laugh or cry.

After closing his eyes and looking into his qi sea, Zhang Tie found that the grey fog had disappeared; however, the battle qi in his qi sea was as thin as oxygen in the plateau. The brilliant sun in the qi sea had disappeared. His battle qi was not as constant as rivers any more; instead, it became a lemon slice which was almost dry and would not produce any juice unless you squeeze it hard.

It was more like a LV 9 soldier's realm.

Zhang Tie revealed a bitter smile as he slowly calmed down. Then he picked himself up and came to the sacrificial altar under the small tree.

"Castle Lord, doesn't it work?"

"No. Without the coordination of battle qi, even if I have enough fire elements, I couldn't light a fire chakra!" Zhang Tie said as he shook his head. This feeling was too depressing. Even if there were a lot of fire elements available, Zhang Tie couldn't take them. It was like how a hungry man couldn't open his mouth when a pile of delicious food was placed right in front of him. He tried to engulf one piece of flesh without the coordination of his battle qi; finally, he had to spurt it out. What was more, he was hurt; despite being not severe. "The fatal strike of an immortal emperor is really tricky. At that time, I felt my qi sea was blown up. Although it was not blown up and I had finally survived, I couldn't recover my battle qi in the qi sea anymore!" As Zhang Tie said, he took a look at Heller, asking, "Oh, do you have any idea..."

"If I had, I would have long told you, Castle Lord!" Heller replied as he watched Zhang Tie seriously, "But I think the sequela left by immortal emperor could be cured in Motian Realm; otherwise, Versatile Demon Emperor has long been unrivaled in this world. Nobody else could defeat him at all..."

"I also think so!" Zhang Tie took a look at the palace tree in a wistful manner as he added, "It seems that I have to finish my vacation in Castle of Black Iron..."

"Castle Lord, where are you going?"

After hearing Heller's words, a place flashed into Zhang Tie's mind at once...
