The fire had been burning, and the entire City of the Dead had turned into a sea of fire, even though they were standing in the sky several kilometers away from the city, Murong Tianhua and Zheng Tian could still feel a huge heat wave coming. Murong Tianhua and Zheng Tian used all their strength to block the attack of the heat wave.

"It seems that this fire will burn for a long time before it is extinguished!" Murong Tianhua said with a calm face.

"Yes, but although this fire is very big, it won't spread to other places!" Zheng Tian said to Murong Tianhua.

"Yes! not bad!" Murong Tianhua nodded and said.

"Brother Tianhua, we should go back! If we don't go back, we still know what Lu Chao and they have done! Presumably they must have noticed what happened here!" Zheng Tian said to Murong Tianhua.

"Hehe! too!" Murong Tianhua said with a smile.

"Then pay more attention! I'll go back!" the Fire Lin Divine Beast said to Murong Tianhua and Zheng Tian, and then turned into a streamer of light and burrowed into the summoning badge on Murong Tianhua's chest.

"This is a summoning badge?" Zheng Tian looked at the summoning badge on Murong Tianhua's chest with some confusion and asked, he had noticed it before, but he hadn't asked.

"Well, the Fire Lin Divine Beast is usually inside!" Murong Tianhua said.

"I see!" Zheng Tian said with a thoughtful nod.

"Okay, let's go, or they should be in a hurry!" Murong Tianhua said with a smile. Then Murong Tianhua and Zheng Tian quickly flew towards the other side of the valley.

Murong Tianhua and Zheng Tian are right, now Lu Chao, Xiong Yan, and Wang Qun are already in a hurry, everyone is very worried about the safety of Murong Tianhua and Zheng Tian, the two of them have been gone all night and have not come back, the three of them are worried to death, but because of their positions, they dare not act rashly. The three of them had to keep sending soldiers to look for the traces of Murong Tianhua and Zheng Tian, because of Murong Tianhua's order before, they couldn't easily go to the City of the Dead without Murong Tianhua's order, so the soldiers of the Holy Martial City sent were only looking for them in the valley, but they still didn't find any trace of Murong Tianhua and Zheng Tian, and when the three of them learned the news, they all showed a worried look.

"No, I have to go to the City of the Dead to find Big Brother!" Lu Chao said worriedly.

"Count me in, too! Even if the City of the Dead is a dead end, I will save my eldest brother from the eldest brother and Zheng Tian from it!" said Xiong Yan on the side.

"You can't do this!" Wang Qun stopped Xiong Yan and Lu Chao.

"Why don't you let us go! Now the eldest brother and Zheng Tian must have had an accident! We must save them!" Lu Chao said loudly as he stared at Wang Qun.

"Yes, Wang Qun! If you don't dare, don't go! Just go with the two of us!" Xiong Yan looked at Wang Qun and said, "Wang Qun! If you're afraid, don't go! Just stay here honestly and wait for our news!"

"I'm not afraid!" Wang Qun said angrily at Lu Chao and Xiong Yan's sarcasm.

"Really, since you're not afraid, why don't you come with us to save Big Brother and Zheng Tian!" Lu Chao said as he looked at Wang Qun.

"I also want to save my eldest brother! But don't forget your duty! Now each of us has an army of 100,000 in our hands, what if we have any more accidents, what will happen to the army?" Wang Qun looked at Lu Chao and Xiong Yan and said.

"Not yet!" Wang Qun said helplessly, "But you two can't leave here! I believe that the eldest brother and Zheng Tian will be fine! Not to mention that the eldest brother still has that divine beast to protect him!

"Then what happened to the fire in the Undead City last night?" Xiong Yan and Lu Chao felt a little relieved after thinking of the Fire Lin Divine Beast beside Murong Tianhua.

"Maybe this fire was set by the eldest brother and Zheng Tian!" Wang Qun said, "We'll wait a minute! The eldest brother and Zheng Tian will definitely come back!"

"Okay! If the eldest brother doesn't come back after an hour, let's go to the City of the Dead to find the eldest brother and Zheng Tian together!" Xiong Yan and Zheng Tian said.

"Okay!If the eldest brother and Zheng Tian don't come back in another hour, I will personally lead the troops to the City of the Dead with you!" Wang Qun said, "We have to believe that the eldest brother and Zheng Tian will be fine!"

"Yes!"

When Murong Tianhua and Zheng Fei flew over the camp, Murong Tianhua and Zheng Tian found that the soldiers of Shengwu City on the ground were all in a hurry, looking anxious.

"Brother Tianhua, it seems that a few of them are really in a hurry! I estimate that if we return a little later, I suspect that they will definitely lead troops to attack the City of the Undead!" Zheng Tian said to Murong Tianhua with a smile.

"There's a good chance they'll do it!" Murong Tianhua said with a smile, "Let's go down quickly!"

"Good!"

When Zheng Tian and Murong Tianhua appeared outside the tent, they immediately caused a lot of commotion.

"The Great General is back!"

"The Great General is back!"

"Go and tell a few adults! Just say that Lord Murong and Master Zheng are back!"

"Yes!"

"Do you need to be so excited?" Murong Tianhua said with a smile. After just a few breaths, Murong Tianhua and Zheng Tian saw Lu Chao, Xiong Yan, Wang Qun, and Mu Yi with the soldiers of the Holy Martial Arts Battalion coming. After everyone saw Murong Tianhua and Zheng Tian, they all knelt on the ground and said, "Big brother, you and Zheng Tian are finally back! We are all worried about you to death!"

"Something happened in the City of the Dead halfway!That's why I'm back now!I'm really sorry to make you all worried!" Murong Tianhua arched his hand and said seriously, seeing so many people worrying about him, Murong Tianhua felt warm in his heart, because Wang Qun and the others were not worried about themselves because of their identity, but a kind of worry between friends, a kind of worry between brothers in life and death, this was what moved Murong Tianhua the most. Zheng Tian also had a strange feeling in his heart.

"Big brother, if you and Zheng Tian don't come back, a few of us will decide to attack the City of the Dead! We will avenge you and Zheng Tian!" Lu Chao looked at Murong Tianhua and Zheng Tian and said.

"What nonsense are you talking about, do you think that Brother Tianhua and I are dead?" Zheng Tian looked at Lu Chao angrily and said.

"What are you still thinking about now, as long as you and your eldest brother are doing well, it's more important than anything else!" Lu Chao said with a smile.

"Yes!" the others chimed in.

"It's good to have you brothers!" Murong Tianhua said from the bottom of his heart. Hearing Murong Tianhua say this, everyone's heart felt a trace of warmth.

"Big brother, what happened to you and Zheng Tian in the City of the Dead?" Xiong Yan asked as he looked at Murong Tianhua and Zheng Tian.

"Let's go! Let's talk about it! This time the matter is very serious!" Murong Tianhua said that his face suddenly became solemn, and even Zheng Tian on the side had a solemn face.

After returning to the camp, Murong Tianhua and Zheng Tian told Wang Qun, Xiong Yan and others about the matter of the City of the Dead, and after everyone heard this terrifying news, everyone's back couldn't help but feel cold. The things that Murong Tianhua and Zheng Tian said were simply incredible, which they couldn't have imagined before. It's horrible. Hearing that the entire City of the Dead was an empty city, and there was not a single soldier of the Wu Clan, they were all used to refine some undead bone demon spiders, this cruel method made Xiong Yan and the others stand on end after hearing it.

"Big brother, is what you said true? This is really terrifying!" Lu Chao said with some difficulty in accepting it.

"I also hope that what I said is false!But in fact, he is true!" Murong Tianhua said with a solemn face, "And it is certain that the Wu Clan will definitely not refine this Bone Demon Spider in one city, and it is very likely that it is also being refined in some cities of other empires!"

"If all these things are used for war, this is really terrible!" Xiong Yan said with some shock.

"That's right!The Wu Clan must have thought so!" Murong Tianhua said, "But refining this Bone Demon Spider requires a large number of corpse bones, which is not a simple matter! And refining is not easy! It is impossible to refine a large number of them in a short period of time! Now we have just refined some! We don't need to worry too much!"

"Yes!"

"Big brother, this city of the dead has been destroyed, so didn't we come here for nothing this time?" Lu Chao said as he looked at Murong Tianhua.

"It's not for nothing!" said Zheng Tian on the side.

"Why?" Lu Chao asked as he looked at Zheng Tian suspiciously.

"Because now we know at least one of the secrets of the Wu Clan about the Bone Demon Spider!" Zheng Tian said, "This way we will have another confidence in dealing with the Wu Clan in the future!"

"Brother Zheng is right!" Murong Tianhua said.

"Now the Undead Bone Demon Spider in the Undead City has been destroyed!But the Undead City has also been destroyed!" Xiong Yan said with some disappointment, "Big brother, what are you going to do with this Undead City?"

"This undead city will definitely be uninhabitable in a short period of time! There is a large amount of necromantic aura in it! It will be difficult to disperse! It may take a few years to recover!" Murong Tianhua said.

"Big brother, then what should we do now?" Lu Chao asked as he looked at Murong Tianhua.

"Go back to Shengwu City!" Murong Tianhua said, "My half-year appointment with Changfeng is almost coming!"

"Yes!"

"But big brother, we don't have any news of Xuanyuan Muxue at all!" Mu Yi said as he looked at Murong Tianhua.

"It's okay if we don't find this! we'll definitely find it if we have the chance!, but now we can already talk to the Emperor of the Star Luo Empire!" Murong Tianhua said.

"Yes!"

"Pass my order! Order all the soldiers to pack their luggage immediately! We will return to Shengwu City immediately!" Murong Tianhua said.

"Yes!" the crowd said, and they all left.

Two days later. Murong Tianhua and the others have led the army back to Shengwu City, and in the past few days, nothing important has happened in Shengwu City, plus there is an old man from Tianzun guarding it, so Murong Tianhua is not worried about the safety of Shengwu City. Then Murong Tianhua found Mu Yi, and after understanding the situation, he asked Mu Yi to continue to manage Shengwu City, while Murong Tianhua went to find the old man Tianzun and told the old man Tianzun about the dead bone demon spider found in the city of the undead.

In the next period of time, Murong Tianhua didn't go anywhere, so he stayed in the Holy Martial City to cultivate martial arts, as well as to cultivate Xie Chao's "Empty Domain Spiritual Technique" to Murong Tianhua, through continuous cultivation, now Murong Tianhua finally began to have a deeper understanding of the power of space, but it was indeed very difficult to use, Murong Tianhua knew that cultivating the power of space was in a hurry, so Murong Tianhua was not in a hurry at all. Murong Tianhua spent more time on cultivating martial arts, and after more than a month of cultivation and more than a month of precipitation before, now Murong Tianhua felt that he had touched the barrier of the Seven Star Dry King. The strength of other people is also growing.

Sometimes Murong Tianhua would also take Yun Xin and Mu Xue around, and to Murong Tianhua's surprise, Mu Xue had also successfully entered the one-star Qianwang realm! It can be seen that this Mu Xue's martial arts cultivation talent is not low. Saint Martial City is still a thriving scene. The combat effectiveness of the entire Shengwu City's army has also increased substantially.

On this day, when Murong Tianhua was discussing some things about martial arts cultivation with the old man Tianzun in the room, he suddenly remembered Mu Yi's voice outside the door: "Big brother, someone wants to see you!" Murong Tianhua walked over and opened the door and asked, "Who?"

"Changfeng!" Mu Yi said with a smile. When Murong Tianhua looked at the position of the old man Tianzun, he found that the old man Tianzun no longer knew when he had disappeared, Murong Tianhua smiled, knowing that the old man Tianzun didn't want to disturb him to deal with things before leaving.

"It looks like the Emperor of the Star Luo Empire can't wait!" Murong Tianhua said with a smile, "Let's go...... Go and see ......"
