Zhang Tie returned to Dragon Emperor City at around 4 pm. It was still sunny in Dragon Emperor City just like usually. During the past 4 days, n.o.body across Dragon Emperor City had discovered that Dragon Emperor was not in the Forbidden City; instead, he had left Dragon Emperor City and "made a big harvest"...

Just like he left there, Zhang Tie returned to Forbidden City secretly through the secret tunnel outside Dragon Emperor City before entering his own backroom for cultivation beneath Jiaotai Palace.

As immortal generals always entered secluded cultivation for a long time, the short period of 4 days was not a big deal for immoral generals. The backroom was as same as before. Leng Manxue had not contacted Zhang Tie; perhaps she thought that Zhang Tie was still inside there. 

After coming back to his backroom, Zhang Tie triggered his body-changing immortal bloodline and recovered his original look. Closely after that, he put on that set of clothes that he got from Si Clan"s castle before burning it into ashes by true dragon flame. By then, he had destroyed all the pieces of evidence of his absence during this period. 

Of course, besides this set of clothes, Zhang Tie also achieved a lot from Cyan Lotus City. 

Qian Changqing"s s.p.a.ce-teleportation finger ring, the s.p.a.ce-teleportation finger ring that Xue Yuxiu had gifted him and the s.p.a.ce-teleportation finger ring of general butler of Si Clan"s castle from General Manager Si were all in Zhang Tie"s hand. In a moment, Zhang Tie had got three more s.p.a.ce-teleportation finger rings. Zhang Tie had been accustomed to this; because Zhang Tie found that he could easily get s.p.a.ce-teleportation equipment since he acquired Castle of Black Iron. It might be very difficult for others to acquire a s.p.a.ce-teleportation finger ring; however, Zhang Tie could always get them easily. Therefore, Zhang Tie almost lost his interest in s.p.a.ce-teleportation equipment. 

Besides the three s.p.a.ce-teleportation equipment, of course, Zhang Tie"s largest achievement was that he had almost completely refined and absorbed Grand Justice Qian"s fire chakra. Plus this nearly complete one, Zhang Tie had almost absorbed the chakras of 5 demon heavenly knights and 1 semi-sage level demon knight, which could enable him to promote to three change realm of heavenly knight steadily. Benefiting from this, Zhang Tie would soon complete one-third of the road towards the semi-sage level knight. What a terrifying cultivation speed!

The s.p.a.ce-teleportation finger ring of General Manager Si contained a lot of items that Si Clan"s castle had collected, mainly great piles of crystal coins, element crystals, some rarities such as Heavenly-Soul incense, some living necessities and some accounting books. Zhang Tie had seen them a few days ago; additionally, Zhang Tie treasured them too much. 

Zhang Tie had not checked the s.p.a.ce-teleportation finger rings of Qian Changqing and Xue Yuxiu. After returning to the cultivation backroom of Forbidden City, Zhang Tie started to check them carefully.

Xue Yuxiu"s s.p.a.ce-teleportation finger ring had a volume of over 200 cubic meters. The finger ring contained a lot of water and wind element crystals, some medicinal powders, wealth, some living necessities and two silver secret items. It was a good treatment for the grand elder of Yin-Yang Sect. In the s.p.a.ce-teleportation finger ring, the most eye-catching things were some items in a box. Zhang Tie penetrated his spiritual energy into it as he saw some letters, a piece of music score and some well-preserved maple leaves. Those letters were written by Brother Luo for her. The piece of music score was also gifted by Brother Luo. Although there was no signature on the maple leaves, Zhang Tie estimated that those maple leaves were also gifted by Brother Luo. Xue Yuxiu preserved these items well. 

Watching these items, Zhang Tie could let out a deep sigh. Pitifully, he couldn"t take all of them out of the s.p.a.ce-teleportation equipment. Otherwise, Zhang Tie would have long burned them for Xue Yuxiu on the riverside of Suns.h.i.+neprospect River a few hours ago.

After checking Xue Yuxiu"s s.p.a.ce-teleportation finger ring, Zhang Tie started to check Qian Changqing"s s.p.a.ce-teleportation finger ring.

Qian Changqing"s s.p.a.ce-teleportation equipment was more senior than that of Xue Yuxiu"s. It contained greater s.p.a.ce. By contrast, the s.p.a.ce-teleportation equipment didn"t contain too many fas.h.i.+onable things. They were medicinal powders, crystal coins, element crystals, some living necessities which were available in emergencies and two secret books just like what the other immortal generals of his level would put in their s.p.a.ce-teleportation equipment. 

If there weren"t anything special in Qian Changqing"s s.p.a.ce-teleportation finger ring, Zhang Tie might be disappointed. Thankfully, Qian Changqing didn"t let Zhang Tie down. Right in his s.p.a.ce-teleportation finger ring, Zhang Tie saw one item that he longed for the most——a 65 cm high black gourd which was covered with flowing bizarre runes.

Zhang Tie was ecstatic in a split second. This gourd was used for storing and releasing Golden-Soul Rune Virus. 

Zhang Tie had seen the same kind of gourd in Qian Changqing"s residence in Si Clan"s castle. However, that gourd was already empty as all the Golden-Soul Rune Virus had been released by Qian Changqing when he raided Yin-Yang Sect. That gourd was meaningless for Zhang Tie. Zhang Tie was afraid that it might incur troubles for him and easily expose his real ident.i.ty if he carried it with him, he didn"t touch it, although the runes on the gourd had some research value. 

However, Zhang Tie found the same kind of gourd in the s.p.a.ce-teleportation finger ring of Qian Changqing. Additionally, the mouth of this gourd was sealed. Given the information that Zhang Tie got from General Manager Si, the Golden-Soul Rune Virus inside this gourd probably had not been used. They might be kept for handing the next batch of targets by Qian Changqing after Yin-Yang Sect. 

If he could get the original Golden-Soul Rune Virus, Zhang Tie, as an immortal craftsman in runes, might be able to discover its secret through study step by step. 

Pitifully, he couldn"t take the gourd out of the s.p.a.ce-teleportation finger ring to study it carefully. Even though Zhang Tie had lotus-flower eyes, he could still not see through the gourd. Even his spiritual energy could only tell him what was inside the gourd. 

However, he would be able to take this gourd out of the s.p.a.ce-teleportation equipment in a few days.

After putting away the two s.p.a.ce-teleportation finger rings, Zhang Tie entered cultivation in this backroom. 

As Zhang Tie had already absorbed a lot of fire elements in Purgatory Samsara Method, it was the right moment for him to turn these fire elements into his own strength. 

As for Cyan Lotus City and Dark Emperor Immortal Palace, Zhang Tie didn"t worry about them for the time being. According to the saying before the Catastrophe in Taixia Country, let the bullet fly. 

If he wanted to figure out the threats facing Dragon Emperor Immortal Palace internally, he had to wait until the event in Cyan Lotus City and Dark Emperor Immortal Palace spread across Motian Realm. Otherwise, if Zhang Tie suddenly wanted to investigate those elders, it was equal to telling them that he had long known the existence of Dark Emperor Immortal Palace and Golden-Soul Rune Virus that they used to control human immortal generals. 

Thankfully, as Dragon Emperor Immortal Palace had tided over the difficulties for so many years, they could still wait for a few days. 

Zhang Tie then continued to light his fire chakra in the backroom rapidly as if nothing had happened. 

3 days later, on March 26th, the 3586th year of Emperor NvWa"s Calendar, Zhang Tie promoted to one change realm of the heavenly knight. On the second day after that, Zhang Tie was finally "awakened" by Leng Manxue. He had to exit the backroom...
