Among all the auxiliary combat power enhancement effects, the fighting soul has always been ranked first, far surpassing things like the natal ghost baby and the natal zombie.

Xu Feng obtained a ghost baby and practiced the Heavenly Eye Ghost Control Technique, and his strength has greatly improved. If he can obtain the fighting spirit in this secret realm, even if he fails to advance, as long as he can save his life and leave, this time he will make a lot of money.

"What about our main mission?" Shui Sheng asked hesitantly.

If you are really determined to obtain the fighting soul, then the rest of your time will probably be spent on collecting information about the fighting soul, and searching for clues to the space transmission node information will naturally have to be put on the back burner.

"If we can really obtain the fighting spirit, the main quest will mean nothing!" Xu Feng couldn't help but shouted.

The information about the fighting souls in the previous life has been kept confidential, but most of the secret realm apostles still know the existence of fighting souls. They just don’t know the specific properties of fighting souls or how to obtain them.

But now, Xu Feng believed that few apostles knew about the existence of the fighting spirit.

"What exactly is a fighting spirit? Would you give up your promotion mission for it?" Shui Sheng showed an incredible look on her face.

"You will know when you get it, and you will never regret it!" Xu Feng said firmly. In fact, he did not fully understand the detailed information of the fighting spirit, but since Guan Ying performed that move, he recognized at a glance that the golden-veined silver-leaf grass was the fighting spirit! The news that Guan Ying hunted down the mutant giant snake quickly spread throughout the camp. After knowing the existence of the snake king's bile, many people came up one after another, wanting to get a share of it.

Xu Feng and the other man waited patiently in the room until the afternoon, when Guan Ying finally came back with a happy look on her face.

"Have all the snake king's bile been sold out?" Xu Feng asked.

"Hehe, there were more than 60 kilograms in total, and they were all sold, but I gave 30% to the camp!" Guan Ying's cheeks were slightly red, as if she was drunk.

It is a rule that the camp gets 30% of the profits. As long as people live in the camp for a long time and are protected by the camp, they don't mind this rule.

However, the snake king has a lot of bile, and 70% of it is enough for Guan Ying to eat a lot.

After returning home, Guan Ying looked at Xu Feng with a trace of embarrassment on her face. In her opinion, she and Xu Feng had hunted the mutant giant snake together, so Xu Feng should naturally have a share of the profits.

But Xu Feng is not a member of their camp. If Xu Feng is willing to join Camp 119, Guan Ying will naturally not be so entangled, and it would not matter to give Xu Feng a share of the benefits. But if Xu Feng leaves Camp 119, then this benefit will invisibly weaken the strength of Camp 119.

"Xu Feng..." Guan Ying showed an embarrassment on her face.

"Haha, Miss Guan, you don't have to be so embarrassed..." Xu Feng smiled and continued, "I have personally experienced the effect of the snake king's bile. It can improve the overall strength of the No. 119 survivor camp. I can give up this benefit, but I also have a few questions that I want to ask Miss Guan!"

When Guan Ying heard what Xu Feng said, she immediately felt relieved. Although she got 70% of the profit from the snake gall, as long as she stayed in the camp for one day, this profit would benefit the entire camp.

"Mr. Xu, please ask, as long as I know it, as long as it does not involve privacy and the secrets of Camp 119, I will tell you without reservation!" Guan Ying said seriously.

"The first question I want to ask is, how do you get the fighting spirit?" Xu Feng's eyes flashed with excitement, and he asked while trying to suppress his excitement.

"Fighting spirit?" Guan Ying's eyes showed confusion, as if she had never heard of this word.

"It's the shadow of the golden-veined silver-leaf grass that appeared behind you when you were fighting before!" Xu Feng said.

"Oh, you are talking about the symbiote!" Guan Ying's face showed a look of realization.

"It's not easy to obtain a symbiote..." Guan Ying explained, "There are more than 500 soldiers in the entire 119 camp, but not even ten of them have obtained a symbiote!"

"Ms. Guan, can you explain to us what a symbiote is?" Shui Sheng couldn't help but ask.

Guan Ying glanced at Shui Sheng. She had no obligation to explain or answer any questions for Shui Sheng, but thinking that this question could be seen as Shui Sheng asking it on behalf of Xu Feng, she did not show any dissatisfaction.

But Shui Sheng immediately understood the meaning of Guan Ying's glance. Her expression changed slightly, and she glared at Xu Feng unhappily and rolled her eyes at him.

Xu Feng was speechless. When hunting the giant snake before, Shui Sheng just watched from the side without taking any action. Naturally, Guan Ying would not have a good face towards her.

"This is because you, Shui Sheng, don't know how to behave. You don't even do things that are easy to do, which makes others unhappy. What does it have to do with me? Why do you blame me in the end?" Xu Feng said in his heart.

"The emergence of symbionts is actually related to those alien creatures..." Guan Ying said: "Even the emergence of so many mutant creatures in this world may be related to those alien creatures!"

…

There is no wrong version in the 1619 book forum!

After Guan Ying's explanation, Xu Feng finally understood the information about the fighting soul. It turned out that the fighting soul was also a special mutant creature.

Most of these special mutant creatures appear in plant form, but they also appear in animal form, but their numbers are extremely rare.

This information opened Xu Feng's eyes. You know, even in his previous life, Xu Feng had only seen fighting spirits in plant form, but had never seen or even heard of fighting spirits in animal form.

"...The special thing about these mutant creatures is that when you kill them, they will drop soul seeds. Then you can use your own mental power to wrap the soul seeds and stimulate their growth. At that time, the soul seeds will be completely integrated with the mental power..."

"...The fusion of spiritual power and soul seed is very dangerous. If you are not careful, the soul seed may become the master and take over the body, becoming the real owner of this body..."

Guan Ying's words made Xu Feng look a little ugly. He didn't expect that obtaining the fighting soul symbiont would be life-threatening. This kind of special mutant creature is said to be a parasite of alien creatures. The so-called dropped soul is also an alien creature in a conscious state. If you want to have a fighting soul of your own, you must defeat the conscious alien creature in the spiritual world. This process is extremely dangerous.

…

"Isn't this too dangerous? The cost-effectiveness is not very high!" Shui Sheng muttered softly, with a look of resistance on her face.

In her opinion, there are many ways to improve strength, but Shui Sheng is somewhat resistant to this method which may endanger her life. As a Taoist priest, she naturally understands how terrifying it is to possess another's body. Compared with death and possession of another's body, both are considered a kind of mercy.
