Su Yu and the others hurriedly retreated as the top experts fought. One could say that Su Yu was the strongest idle combatant left in the hall. He stood guard before Dao Cheng and dispersed the rippling source qi in the air. Alarmed, Xuan Wuji sent him a voice transmission, "Ling Heng, go open the gate. Do it while they are occupied!" However, Su Yu ignored the order. He only focused on protecting Dao Cheng. Dao Cheng said nothing. All the top experts were fighting near the throne. If Ling Heng were to approach the throne, he would probably die from a random slap of these experts. Thus, Dao Cheng understood Ling Heng's hesitation. Looking at the mad Mo Duona and the intense battles in the hall, Dao Cheng felt both anxious and helpless. What was going on? He had thought that his senior brother would be the one in danger. But that wasn't the case. Mo Duona was trying to kill them all for no reason. Why was this happening? Suddenly, Mo Duona roared and grew multiple times larger. With his massive palm, he grabbed the eighth-stage Sunmoon and crushed the Sunmoon into mincemeat. While doing so, he ignored the attacks of the other three Sunmoons, allowing them to land on his body. After crushing the eighth-stage Sunmoon, a shining ball appeared in his hand. That was the Sunmoon's sea of willpower. With a hearty laugh, he tossed the ball into his mouth. "If you don't kill me, I'll kill you all!" After witnessing Mo Duona's madness, the three ninth-stage Sunmoons grew even more anxious. They stopped holding back and started attacking with their full power. The battle increased in intensity. Mo Duona was being serious here. He was really trying to kill them. They wouldn't be able to talk this out. The dead eighth-stage Sunmoon was the proof. "Kill him! Even with the blood essence of the Devil Pseudo Emperor, he won't be able to last too long! Kill him!" Yang Hu continued shouting his orders. An eighth-stage Sunmoon had died so easily. Just then, Zhankui punched through reality and time seemed to flow in reverse. Yang Hu, who had moved slightly to the side, was suddenly pulled toward Zhankui's fist. With a spurt, Zhankui stabbed through Yang Hu's shoulder with his hand. Yang Hu's expression changed. "Zhankui, are you really trying to kill me?" Yang Hu was furious. Zhankui did not bother to say anything. With Mo Duona going crazy, he had to act decisively. If he could kill Yang Hu, things would still remain under his control. If he allowed things to continue, Mo Duona might end up killing Xuan Wuji and the others. That would be extremely troublesome. "You're courting death!" Yang Hu roared furiously. Did Zhankui think that a mere present body was enough to defeat him? A river of time appeared as Yang Hu summoned his past body and fused both bodies. Then, he swung his sword at Zhankui from moments ago instead of from the present. Zhankui's expression turned cold as he discovered that Yang Hu had a decent mastery over the power of time. Meanwhile, Su Yu only focused on protecting Dao Cheng from the shockwaves rippling all over the hall. Suddenly, he roared, "Princes, hide at the corner! I will provide cover for you!" Xuan Wuji and the others glared at him furiously, but they said nothing and did as told. Looking at Mo Duona, who was facing three ninth-stage Sunmoons, Xuan Wuji gnashed his teeth and said, "He won't be able to last long. The Devil Pseudo Emperor won't be able to transmit more strength into the mansion. He's relying on only the blood essence. When the blood essence runs out of power, he won't be able to keep fighting with such strength." As a first-stage Mountainsea, Mo Duona was suppressing the three ninth-stage Sunmoons facing him. It was unbelievable how powerful a single drop of blood essence from the Devil Pseudo Emperor was. One ought to know that Mo Duona wasn't using the blood essence like Su Yu. The blood essence might have originated from a Daofuse, but it wouldn't provide Mo Duona with the strength of a Daofuse. Rather, it would only strengthen him to his limits. If he could withstand the pressure, he would be able to unleash a much higher level of strength. Clearly, Mo Duona had succeeded in withstanding the pressure as he was fighting with the strength of a ninth-stage Sunmoon. This alone made it clear that he was far stronger than Xuan Wuji and the others. Back during the battle in the Human Realm, they had also utilized the power of the elders. However, they had not been able to surpass the eighth-stage Sunmoon Realm. At the time, Su Yu had fought them personally. One could hear a tiny bit of envy in Xuan Wuji's voice. He sneered and continued, "Even if he could survive this, he would turn into a part of the Devil Pseudo Emperor after leaving the mansion." As far as he was concerned, this was the end of Mo Duona. The proud and undefeatable Mo Duona was no more. For Xuan Wuji, this was merely Mo Duona's final struggle before his end. Meanwhile, Dao Cheng was still trying to divine their fate. After coughing a mouthful of blood, he grew even more alarmed. Why? Why was his divination still telling him that he was perfectly safe? Was there no risk for him? Or perhaps he was trying to divine people far beyond his level, hence the inaccurate results? Was that the case? Xuan Wuji asked, "What's the result?" "Things are looking very good for us." Dao Cheng was being honest. That was the result of his divination. How was this looking good to them? Why? Xuan Wuji was quite surprised as well. After blanking out momentarily, he said, "Perhaps that's the case. It is likely that Mo Duona has a lot of treasures on him. After defeating him, those treasures will be ours." Through Dao Cheng's divination, he became a lot more certain. There was no danger for them. Things were looking very good for them. However, Dao Cheng was finding it hard to believe his own divination results. Once again, he tried divining Ling Heng's fate. Once again, he was told that things were dangerous for Ling Heng. Would his senior brother be the only person to die here? Would his senior brother die while protecting them? And after that moment of danger, great things would happen to the rest of them? Su Yu, who was facing them with his back, grinned. How was Dao Cheng liking his divination results? Dao Cheng should really stop embarrassing himself with his poor divination skills. Even someone as strong as Wan Tiansheng had only been able to see a glimpse of the future through a heaven weapon and a sacrifice of his lifespan. Wan Tiansheng had sacrificed about a hundred years of his lifespan for that. Meanwhile, Dao Cheng was relying only on his own characters. He must be dreaming. There were millions upon millions of possibilities in the future. Someone like Dao Cheng could probably see only one of those possibilities. How could his divination be accurate? As a cultural researcher, Su Yu did not fear the art of divination. That was merely an extension of what a cultural researcher could do. Thus, he held zero fear toward Dao Cheng. Su Yu ignored the people behind him and focused on the three battles in front of him. He frowned slightly. This wouldn't be an easy task to accomplish. It would be pointless for him to do anything before the two Pseudo Invincibles were dead or gravely injured. He might be strong, but he wasn't strong enough to defeat two Pseudo Invincibles. Even with his yang acupoint open and a drop of peak ninth-stage Sunmoon blood essence, he would only be as strong as a peak ninth-stage Sunmoon. He did not have the blood essence of Pseudo Invincibles or he wouldn't mind trying using some. Thus, he had to wait until the two Pseudo Invincibles were sufficiently injured before making his move. The ninth-stage Sunmoons were of no concern to him. There were quite a lot of them, but he could still handle them. Suddenly, a spear appeared in Mo Duona's hands. He pushed it out and stabbed through one of the ninth-stage Sunmoons. Taihe roared in alarm. He wasn't surprised to see a heaven weapon in Mo Duona's hand. Rather, he was more surprised that Mo Duona was proficient with a spear. Wasn't Mo Duona supposed to be proficient at fist techniques instead? But the existence of the spear proved that Mo Duona was good at it. He wouldn't have forged a heaven-grade spear otherwise. As the ninth-stage Sunmoon stabbed by Mo Duona attempted to flee, a clump of flame appeared on Mo Duona's forehead. Instantly, the ninth-stage Sunmoon was set aflame. He started wailing in pain. "Cultural researcher!" Both Zhankui and Yang Hu exclaimed in alarm. Cultural researcher! Not only was Mo Duona a cultural researcher, but he was a ninth-stage Mountainsea in willpower cultivation. That shouldn't be possible. Mo Duona was supposed to be a first-stage Mountainsea. That was the record on the Heavenly Hunt Index. But soon, Zhankui and the others thought of something. Su Yu thought of the same thing as well. Like Chen Yong, Mo Duona was a cultural researcher who had been stuck at the ninth-stage Cloudbreach Realm for a long time. He had fused almost all his apertures long ago, leaving only one aperture unfused. After entering the Luminous Domain Mansion, he could fuse the final aperture and reach the ninth-stage Mountainsea Realm directly. The ninth-stage Sunmoon would not fear this flame normally, but he had been injured by Mo Duona's spear. Thus, he was unable to resist. Mo Duona followed with a kick, blasting the ninth-stage Sunmoon apart. That left only Taihe and a fairy immortal. The two retreated in alarm. It hadn't even been long yet two of them had perished. Meanwhile, Mo Duona looked completely unaffected. He was actually a ninth-stage Mountainsea cultural researcher. He had proven his strength. Alone, he fought four Sunmoons. In less than a minute, he defeated two of them. With two fewer opponents, the balance shifted completely.
