The continuous emergence of new technologies made both sides a little afraid. Chang Xi not only stopped marching, but also retreated for a while, narrowed the defense range behind him, and at the same time placed the base camp in a valley. It was always floating in the sky, which was not a good feeling, and it still had to be down-to-earth.

There is no way to do this. The blood and qi mask relies too much on the supply of blood and qi. If the supply is completely cut off, the main force will be very dangerous and must be consolidated in the rear.

On this day, Chang Xi and Nirvana took a walk on the mountain path.

"Moon Mother, I think instead of spending energy studying the other party's technology, it is better to concentrate on continuing to develop our aura."

Nirvana says.

Chang Xi looked at Nirvana in confusion. Recently, there seemed to be no big breakthrough in the purification pool.

Nirvana said: "At present, our problem is mainly to supply the rear, not to be unable to defeat the other party in the front. As long as the logistics problem is solved, even if the other party knows our every move, we are not afraid. If we can directly place the purification pool on the spacecraft, then we do not need to rely on a large number of supply ships to replenish us. We can use war to support the war, and the spacecraft is moving and can purify more souls."

Chang Xi frowned and said, "We have discussed this point today, but do you say that the purification pool cannot be installed on the spacecraft?"

Nirvana said: "That's because we never thought about using human power systems to operate the purification pool."

Chang Xi was a little confused and said, "How can this be done with the human power system to operate the purification pool? The purification pool requires the spiritual energy of our spirit clan to operate, and this is different from human technology."

Nirvana smiled and said, "I have carefully observed human technology. Their fuel is stored in fuel tanks. The fuel tank operates itself and provides power to the aircraft. Our previous purification pools and blood springs were all placed using the natural environment. Although our aura is completely different from the other party's technology, the principles of spacecraft and aircraft are the same.

We can use the human technology and technology to our purification pool, and package the purification pool, blood spring, and spiritual energy with the human power system to form a purification pool system that integrates the human power system and our purification pool. Regarding this, I have discussed it with those beasts, and they think it is also feasible.

As long as we can think of ways to make the spiritual energy, blood springs, and purification pools storeable, they can use human technology to place these on the spacecraft. If it can be successful, our blood hood can be opened longer, and the power of our spacecraft is stronger than before."

Chang Xi was delighted to hear this and said, "If this can succeed, then we will be invincible."

If this is the case, it is eternal power, and the spacecraft can never fall. In theory, blood and energy waves are infinitely emitted.

It's beautiful to think about it!

"Moon Mother."

At this time, Su Nu suddenly came over and nodded slightly to Nirvana.

Nirvana nodded with a smile and said, "You talk."

After saying that, he left.

When Su Nu saw that Chang Xi's expression had changed, she couldn't help but say, "Mother Yue, what are you talking about just now?"

Chang Xi said: "It's about the purification pool. I'll tell you later. What are you asking for me?"

Su Nv sighed softly: "It's about bat beasts. We have studied those planes and found that later planes were coated with a kind of paint, and this paint is very similar to the fur of a moth. This moth cannot be detected by bat beasts with sound waves because there are many small holes on it that can absorb the sound waves of bat beasts. Although we have found out the reason, unless the bat beast evolves again, we can no longer use bat beasts to discover enemy aircraft."

Chang Xi frowned when he heard this. The invisible technology and detection technology made them very passive.

And the proposal for Nirvana over there does not mean that it will definitely succeed, even if it succeeds, it will take time.

Just then, I suddenly heard a hoarse voice, "I can help you!"

"Who is it?"

Chang Xi's face was shocked.

Upon hearing this, Su Nu couldn't help but look around, then looked at Chang Xi curiously and said, "There is no one around!"

Chang Xi said: "Didn't you hear it just now?"

"What did you hear?"

Su Nu said in surprise.

Chang Xi frowned slightly and then said, "Maybe I'm a little tired recently. If nothing else, you can go back first. I want to take a rest."

Su Nu was stunned for a moment and then said, "Yes."

After Su Nu left, Chang Xi suddenly asked in a low voice: "Who are you?"

The hoarse voice laughed, "Where do you forget my voice so soon?"

"Emperor of Heaven?" Chang Xi said.

"Ha ha!"

"Why are you inside me?" Chang Xi asked.

She had already clearly felt that the sound did not come from outside, but from inside her.

"I'm not in your body, but when you were destroying Tianchi, you inhaled some spiritual energy in my body, so I can communicate with you. You seem to be in some trouble now."

"What does this have to do with you?"

"I can help you. You should be clear about the talent of our Emperor's Vein. I can change the blood factor of the bat beasts to make them have stronger sound waves... In fact, there is no need to do this, because I can create a perfect alien like Kunlun Mother, and at the same time, I can have the sound waves of the bat beasts. It is just a breeze to destroy the Huaxia Alliance."

"You are dead, your soul does not have the blood of the Emperor's vein."

"That's not necessarily. As the Emperor of Heaven, I am naturally different from other imperial veins. My soul retains the blood factor. As long as you inhale my soul into your body, I can combine my blood factor with your eyes, so that you can have my imperial vein blood and also have the long-lost blood factor technology."

Chang Xi's eyes flashed a few times and said, "After all, you just need a body, I can find another body for you."

"If it's so simple, would I be afraid to come to you? There are many sorcerers by the Tianchi Lake, but only your body, Chang Xi, can combine with my soul, because you are the most perfect spiritual race, and the spiritual energy in your body is also the most perfect, and can be merged with the soul."

"Then you save money."

Chang Xi sneered.

"Why? Don't you want to win and become the master of this land."

"Of course I want to. But..."

Chang Xi smiled and said, "But I am even more afraid of being controlled by you. After all, your Heavenly Emperor clan was the founder of this continent. I think any race will be afraid of you. You can create a perfect alien race and also create a perfect spiritual race. At that time, your Heavenly Emperor lineage can use our spiritual race to return to the continent. However, if you are willing to help me, I can consider making your life easier."

"Haha...do you think I will believe you? Once you win, you will surely kill us, but if you promise to cooperate with me, we will rule this continent with your spiritual race, just like in the past, and I cannot control you, because we are fusion, not replacement."

"Then we have nothing to talk about. Oh, our spiritual race is no worse than you. We are enough to rule this continent with our own strength."

Chang Xi smiled coldly and said, "Are you leaving by yourself or I do it yourself to make you a wisp of blue smoke."

"I will wait for you in Tianchi."

"After the war is over, I will go to Tianchi and completely destroy you."

Chang Xi snorted lightly and turned around and left.

She was so arrogant, how could she be willing to combine the ugly soul of the Heavenly Emperor with herself?

Shortly after she left, a beautiful figure came out of a big tree in the distance. It was Su Nu. She looked at Chang Xi in surprise.

......

At the same time, the Allies were also trying their best to crack the other party's secrets, and even let Houtu and Taiyi venture into the territory controlled by the other party to explore the vortex and blood fountain.

It is said to be risky, but it is not very dangerous, because Chang Xi and his team have very weak control over the ground, and the Allies have long sent assassination legions to sneak into it. In addition, the radar, as long as the plan is carefully planned, they will generally not be discovered.

Houtu and Taiyi also arrived at the Xixi Crypt successfully. They had already received instructions. The assassination legion that was being responded to here immediately took them to the bottom of an abyss.

"General, are they not usually stationed here?"

Houtu asked while walking, thinking about General Baihu beside him.

The White Tiger General shook his head and said, "After receiving the order, we have been observing here secretly. They have only been here once, but since they are all spiritual warlocks, we are afraid of being discovered by them, so we dare not get too close to them and cannot see how they extracted blood and energy from it."

Houtu nodded.

After walking for a while, they came to the purification pool and saw three blood fountains constantly bulging out bubbles, as if boiling water, but the red steam coming out of the blood fountains kept sucking in the middle.

After all, the photos are very blurry. When I saw them with my own eyes, Houtu and Taiyi couldn't help but look at each other, with surprise in their eyes.

"This is amazing!"

Taiyi walked forward, suddenly his nose twitched, and asked Houtu again: "Do you smell it?"

Houtu nodded and said, "It's the smell of blood."

Taiyi squatted down, stared at the blood fountain, and said, "This looks a bit like the spring of eternal life."

Hou Tu also squatted down, looked at it for a while, nodded, and said, "But the Spring of Eternal Life is not blood-red unless..."

"Unless they inject blood into it, can blood improve the spring of eternal life?" Taiyi said thoughtfully.

"I think this may have something to do with the vortex in the middle."

Houtu and Taiyi came to the vortex in the middle again.

Hou Tu suddenly frowned slightly and asked Taiyi: "Did you hear it?"

Taiyi said in surprise: "What did you hear?"

"Crying."

"Cry?"

Taiyi shook his head and said, "I haven't heard any crying."

"Is that true?" Hou Tu showed confusion on his face, and slowly squatted down, staring at the vortex. After a while, she suddenly stretched her hand slowly towards the vortex.

"What are you doing?"

Taiyi said in surprise.

Houtu seemed to have not heard it, and he reached into the purification pool like an possessive demon.

Suddenly, her beautiful eyes opened and tears gathered in her eyes.

"Spirit Lord, Spirit Lord. What are you?"

Taiyi shouted worriedly.

Hou Tu ignored it, but the tears kept falling like pearls with broken threads.

Seeing that the situation was not good, Taiyi wanted to step forward and push Houtu away. Houtu suddenly withdrew his hand and said to Taiyi: "Don't worry, I'm fine."

Taiyi was stunned for a moment and said, "But you---!"

Houtu's expression was dim and he said quietly: "I already know what the 'disappeared spiritual energy' is."

Taiyi was overjoyed and asked hurriedly: "What is it?"
