Living creatures fight against the dead. Ye Feng rushed straight with his sword, and the dead bone bird was unwilling to show weakness. After dispersing, Ye Feng surrounded him. This time, Ye Feng attacked in the air. From a distance, it was like a ball made of white bones, rolling in the air.

Meet again, the dead bone bird is still the eye of ghost fire, with a sharp mouth and claws. But after half a year's hard cultivation, Ye Feng had a little more anger in his sword mind. As long as those ghost fire eyes were touched, even if they were not extinguished at that time, they would be constantly burned by the earth spirit fire and finally refined into a wisp of aura.

Moreover, because it directly burns the soul, those slightly larger undead bone birds will even send out a cry on the soul while frantically biting their companions and capturing their ghost fire. Many peripheral dead bone birds were swallowed up by their companions without seeing Ye Feng.

When Ye Feng killed the dead bone bird before, he had never heard a similar cry, nor had he seen any dead bone bird that would attack the same species and seize the ghost fire. Seeing this, I naturally understand that it is the credit of the earth spirit fire. But Ye Feng's earth spirit fire is just a spark given by fire. Why can it grow in its own body and integrate into true Qi?

Facing the undead bone bird without threat, Ye Feng's mind changed from killing to understanding the earth spirit fire and his true Qi. He was no longer in a hurry to kill those dead bone birds. After each sword intention was shot, he would release soul power, carefully feel each other's cry and feel the changes of those dead under the earth spirit fire. Once in a while, after grabbing a wisp of aura, you should not swallow it casually, but send it to the Dantian to let Jianying slowly feel the mystery.

Ye Feng enters the state of perception, and he is immersed in it. But in Bai Jie's eyes, Ye Feng, who stands with a sword in the air and kills the dead bone bird between his fingers, is very natural and unrestrained. But when all the dead bone birds were killed and Ye Feng was still motionless, Bai Jie was a little afraid and flew over to check, but the fire stood in front of her.

"The master is feeling my earthly fire. Bad women are not allowed to disturb!" Huoer said proudly.

Feeling is the most rare opportunity for Feixian, but the Gobi Shiyuan is full of crisis. Feeling in such a deadly place is like looking for death!

"Huo'er is not allowed to scream. This is the beloved of the master. If you don't respect her, how can you call a bad woman!" when Bai jiezheng was anxious, Ye Feng opened his eyes.

"Have you really realized anything?" Bai Jie asked with some guilt.

"Fire is the spirit of heaven and earth. The earth spirit fire carries the laws of heaven and earth. It's not so easy to understand. It's just that some things don't understand and are stunned for a while." Ye Feng said with a smile, pulled Bai Jie with a guilty face and flew towards the camp.

The next day, Ye Feng divided thousands of strong men into two groups. One group was sent to cut down trees in the wild forest, and he took the other group on a road paving trip. Because they dare not go too deep, their so-called paving is to collect the soil produced by digging the tunnel in Najie, and then give it to Ye Feng to take away. Moreover, with yesterday's World War I, Ye Feng was not in a hurry to explore the Gobi Shiyuan. While accompanying the joint repair above Baijie tunnel, he continued his feelings of yesterday.

In the first world war yesterday, Ye Feng killed thousands of dead bone birds. Although most of the booty was robbed and eaten by Huoer, Ye Feng also got more than a dozen. When Jianying felt them, these auras were assimilated in Ye Feng's Dantian, and finally gave birth to a feeling of deja vu - Chu Ling!

"That's not Chu Ling! At most, it's just the breath!" Chu Ling replied to Ye Feng's confusion.

The first spirit is formed by the condensation of chaotic Qi when heaven and earth first opened. She said the breath was similar, that is to say, these undead are returning to their origin. The earth spirit fire of Huoer is the fire of origin. It can destroy the undead, which is normal. But what is this origin? What does it have to do with the law?

Understanding the law and origin is not a matter of time. Ye Feng sat down from morning to night. The trolls dug the tunnels more than ten times. He didn't want to understand a bit. But in the evening, Bai Jie told Ye Feng that he was a little different today.

"Well..."

"What do you think? I mean your true Qi when I say different!" Bai Jiehong shouted with a red face.

"How... Different?"

"Hate, I don't know!"

Bai Jie couldn't say anything different. Ye Feng couldn't help it. The next day, he took people to dig a tunnel as usual. However, since the first batch of wood has been transported, the underground cave can be supported with wood today, so Ye Feng is ready to let everyone rest directly in the underground cave.

During the day, everything is normal in the ancient swamp. The giant spirit family is tall and powerful. They do these heavy tasks very quickly. But in the evening, people have to rest and eat. The figure of several transparent giants appears in Ye Feng's vision!

The giant spirit clan is belligerent, but in the face of this soul monster, they are also trembling. Without waiting for Ye Feng to speak, a group of people went into the tunnel one after another. Finally, they blocked the hole with soil and wood!

"Your men are really good enough to sell you when there is danger."

"Wrong, it's our men." Ye Feng smiled and took Bai Jie to hide at the entrance of the underground cave. He took the fire sword and met the transparent giants.

Ye Feng once destroyed many transparent monsters, but at that time, Ye Ling was badly hit by the natural disaster. In order to help her recover, Ye Feng sent those auras to the Qingfeng treasure armour. In addition, Huoer stole food from time to time. Even if ye Feng caught some, he didn't check it carefully. Now with the doubts brought by the dead bone bird, Ye Feng is ready to catch some Reiki and study it carefully to see if he can gain more.

"Huoer, wait for the aura of those monsters. The master is useful. You are not allowed to steal."

"Can't you taste it?" Huoer kicked his little feet and asked with a smile.

"Then try one, or you'll eat it all. I have to run to other places to find it."

"The monster's baby belongs to me, or I'll rob you."

The transparent monsters wandered from other places. Even if there were treasures, they didn't know where to hide them. Therefore, after Ye Feng easily killed several transparent monsters, the fire who didn't catch anything shouted that he was deceived. Finally, he relied on Ye Feng's five fairy crystals to go back to practice. Ye Feng was used to the fire. Now with those auras, he didn't care more. He opened the tunnel entrance and ordered the Juling clan to rest in place. He continued his previous understanding at the entrance.

As soon as the Reiki from the transparent giant beast was sent to the Dantian, it was swallowed up by the Reiki gathered together before. Finally, it becomes a big bean air mass and walks in Ye Feng's Dantian to absorb Ye Feng's true Qi. Every time Jianying wants to touch it, it is like a prophet and slips away in advance.
