Holy City.

"Annihilation, did we go to the wrong place?" The Dragon Emperor Liekong was stunned when he saw the empty holy city. The holy city where several Emperor Tribulation powerhouses gathered were connected together.

"You can't be wrong. This emperor will never forget what the Holy City is like." An Mie Longdi shook his head and said.

"Could it be that the people inside are hiding?"

"Chi Xiao, have you been confused? We are the Dragon Emperor of Nine Ranks, don't you think that all those ants can hide from our eyes?" Lie Kong looked at Chi Xiao Dragon Emperor contemptuously, road.

"It's not just that, have you noticed that when we passed by other cities, we didn't sense any human breath at all, except for that group of troops just now..." An Mie Long Di found something wrong and said My own opinion.

"Could it be that the Sacred Heart has been destroyed?"

"It's not being wiped out, but it's being gathered together!" An Mie Longdi snorted coldly, "The emperor likes to deal with clusters of humans the most. They are really ignorant!"

"Collected?" The other dragon emperors were startled at first.

"But we can't perceive their aura. It seems that the current ruler of the Sacred Heart Empire should not be underestimated!" An Mie Longdi said.

"Then we are now?"

"The army is divided into four groups, and the Sacred Heart Empire has a huge territory. This is the only way to do it when you can't feel the breath." An Mielongdi thought for a while and said, "Once you find a human gathering place, immediately send a message to the other three emperors. Remember , don't act alone!"

"Just follow what brother An Mie said!" Several dragons agreed with this method.

……

Qixin City, the central command room.

Since the technology level was raised to level [-], the spy satellite's functions have been greatly improved. Even the dragon emperors have never noticed that Lin Xuan's every move is under the eyes of Lin Xuan.

"These four dragons are all rank nine..." Lin Xuan looked solemn like never before.

"The four Martial Emperor-level alien beasts are still ancient beasts. It may not be easy to deal with them..." Chu Mengxuan's face was also extremely serious. These Dragon Emperors were just the first batch.

"They want to act together, but I can use the lightning storm to keep them all, and let the three heroes and Lin Kong complete the final blow." Lin Xuan is not afraid of them, but hopes that they will come to the door.

What worries Lin Xuan is that once he uses the lightning storm, he will lose his last resort. Once a new beast is released, Lin Xuan's Qixin City will surely face annihilation.

"But, that's your last hole card!"

"So that's what I'm worried about. Now I can only hope that Yunru will hurry up. When Uncle Chu breaks through to the peak of Emperor Wu, maybe he can get entangled with the four-headed dragon..." Lin Xuan said with a sigh.

At the same time, countless beasts mutated in the empire.

Under their ravages, in just one day, those empty cities that had been transferred were all turned into ruins. In the end, they all approached a dozen cities with Qixin City as the core.

Following the footprints of these strange beasts, the dragon masters also successfully found the super fortress built by Lin Xuan.

……

"Commander, I've researched it thoroughly!" At this time, Yun Ru's news seemed to be a sedative, which relaxed Lin Xuan's tense nerves.

"Warriors are carriers of soluble biological energy. Different people have different degrees of affinity. This kind of affinity is called martial arts talent by martial artists in this world." Yunru took out an experiment report, Said, "From my understanding, the affinity of the leader of Chu is still very high. The reason why he can't break through to the peak of Emperor Wu for a long time is because the relationship between Yi Rong's biological energy and the carrier has not reached a saturation state."

"So, as long as Uncle Chu absorbs energy crazily, that's enough?" Lin Xuan asked.

"Of course it's not that simple. This saturation must be controlled within a certain limit. If it's too much, it's easy to explode, and if it's too little, it's easy to lose. It still can't reach that critical point." Yunru said, "So , Warriors are constantly trying to find that suitable range, once the fusible biological energy in the body reaches that critical range, it will be their breakthrough opportunity."

"So, can you help them find that tipping point?"

"The critical point can only be grasped by themselves, but I can help them enter that critical range, that is to say, I can provide them with breakthrough opportunities infinitely." Yun Ru said.

"Give us unlimited opportunities to break through? Sister Yunru, is what you said true?" Chu Mengxuan was stunned. You know, breaking through opportunities is hard to come by. Say, she can offer them unlimited times?
"Yes, although I used a lot of technical terms just now, I think you should understand the general meaning." Yunru nodded and said.

"However, the spiritual power we need is huge, why do you..." Chu Mengxuan asked.

"Don't worry, I have already prepared for this. Before that, I prepared an energy converter, which can convert electricity into the world's easy-to-melt bioenergy. Although there are many restrictions, there is still no way to provide the energy needed for Emperor Wu's peak breakthrough. What's the problem." Yunru was very thoughtful, and when Lin Xuan gave her the few materials, she researched the energy converter by herself.

"Then now, can Uncle Chu and Mengxuan break through immediately?"

"Theoretically, there is no problem, but there are certain risks..." Yunru hesitated and said.

"It doesn't matter. A warrior's breakthrough is to go against the sky. If he is not willing to take even a little risk, even if he breaks through, the final achievement is quite limited." Chu Tianxing walked out slowly, heartily laughed.

"father!"

"Xiaoxuan, are you willing to take such a small risk?" Chu Tianxing asked.

"Father, don't underestimate me. With this level, how can my daughter shrink back?" Chu Mengxuan immediately expressed her position without fear.

"Miss Yunru, please start." Chu Tianxing smiled, turned and said to Yunru.

"Commander?" Yun Ru looked at Lin Xuan again. After all, these two were very close to Lin Xuan. If Lin Xuan didn't agree, she wouldn't dare to act rashly.

Lin Xuan looked at Chu Tianxing's father and daughter, and nodded slightly.

"Leader Chu, Sister Mengxuan, this way please!"
