According to the analysis of the old army, if Tang Yao wants to improve his strength to another level within seven days, he must specialize in one, and at present, Tang Yao's best control is Obsidian, so if he wants to improve his strength within seven days, then Obsidian is the best choice.

Obsidian has two major functions at present, the first is to serve as a place for the ancient spirits to recuperate, and the second is to help Tang Yao subdue the ancient spirits, but at present, Tang Yao only uses the first function, and regards the obsidian as Shen Tuya's home, and he has never done it and doesn't know what to do when he subdues the ancient spirits.

Facing Tang Yao's question, the old army nodded and said, "Gu Ling is indeed the way to help you improve your strength as soon as possible at present, whether it is capturing Gu Ling, or using other Gu Ling to strengthen Shen Tu Ya, it can help you strengthen your combat effectiveness." ”

"Oh, you can also use other ancient spirits to strengthen Shentu Tooth, how do you do this?" Tang Yao asked.

At this time, Master Sonomoto, who was standing on the side, spoke: "In the end, the ancient spirit is actually just the embodiment of the energy of qi or magnetic field, when the ancient spirit is broken, it will turn back into a simple energy body, if you can use obsidian to collect these energies, and apply these energies to Shen Tuya's body, then you can strengthen Shen Tuya, this kind of strengthening is divided into two types: temporary and permanent." ”

Tang Yao understood and quickly said: "This is the same as playing a game, getting equipment and breaking it down into materials, and then using materials to strengthen other equipment, I understand." ”

"Ahem, don't talk about games all day long, now let's get down to business." The old army reproached dissatisfiedly, and Tang Yao hurriedly shrank his head and stopped speaking.

Master Sonomoto continued: "The main reason for Shen Tuya's current lack of strength is you, as an ancient spirit, under normal circumstances, the channel for obtaining energy comes from you, the master, if you can't provide Shen Tu Ya with the energy to release all your strength, Shen Tu Ya can only reduce his strength to cooperate with you, which has caused Shen Tu Ya to be unable to recover his strength, and you may not know that if Shen Tu Ya continues to maintain this state of suppressing his own strength, it is likely that one day in the future, the upper limit of his strength will fall, In other words, he will never return to his peak form. ”

Master Yuanmoto's words really surprised Tang Yao, Tang Yao had never heard Shen Tuya talk about it, although Shen Tuya always complained about Tang Yao's lack of strength intentionally or unintentionally affected him, but he didn't say that this situation might have a permanent impact, it was obvious that Shen Tuya didn't know but didn't want to say it.

"Is there a way to stop this from happening?" Tang Yao asked.

"Yes, since your own strength can't be improved in a short period of time, then you can only find another way, smash other ancient spirits, and then use their energy to provide Shen Tu Ya, when Shen Tu Ya's strength gradually recovers, naturally your combat power will also go to a higher level, Shen Tu Ya is still quite loyal to you."

This sentence seemed to be fine, but to Tang Yao's ears, it was a different matter, because in his opinion, the ancient spirit was not a tool and preferred to live things.

Therefore, in Tang Yao's opinion, Master Yuanmoto's proposal was tantamount to asking Tang Yao to kill these ancient spirits, and then use these ancient spirits to feed Shen Tuya, which sounded so evil.

"That's not good, first of all, aren't the ancient spirits all subservient to the illusionists, can't we rob other illusionists to rob the ancient spirits, I'm afraid it will cause a lot of trouble, and then kill the other ancient spirits to recharge the Shen Tu Tooth, this ...... How doesn't it feel like it's the right way. Tang Yao said hesitantly.

The old soldier on the side interjected: "What do you kid know about the difference between good and evil, and besides, who told you that the ancient spirits all have masters?" ”

"Oh? And the wandering independent Ancients? Tang Yao asked.

The old army nodded and said, "Not only there are, but there are many, and even many have been witnessed by ordinary people, which has also caused a lot of strange stories, and even many people regard these ancient spirits as ghosts and ghosts or something." ”

"Oh? I don't understand, don't all the energy of the ancient spirits come from human beings, if there is no energy supply, where do these wandering ancient spirits get the energy? Tang Yao asked.

"Between heaven and earth." Master Yuanben gave Tang Yao a very mysterious answer.

"What do you mean, what do you mean between heaven and earth?" Tang Yao asked.

"Do you think the qi produced by our Qi refining is our own or Heaven and Earth?" Master Sonomoto asked.

Tang Yao thought for a while and said, "Of course it's our own, because only I can control the qi in my body, so these qi belong to me. ”

Master Yuanben shook his head and said, "But you are also a member of the nature of heaven and earth, right?" ”

Tang Yao was a smart man, he quickly understood what Master Yuanmoto meant by this, human beings are also a part of the nature of heaven and earth, so the qi produced in Tang Yao's body is actually one of the nature of heaven and earth, in other words, this answer is still heaven and earth.

"The answer is heaven and earth, you and I are just users of qi but not the master, the master is the nature of heaven and earth, people always feel that they are beyond nature but forget that they are a member of nature, after the ancient spirit is broken, it will turn into a unique energy floating between heaven and earth, human beings are not, after death, the original life energy will return to heaven and earth, and a part of the ancient spirits who have lost their master will absorb this energy wandering between heaven and earth, and transform this energy into their own energy, and eventually exist."

Hearing this, Tang Yao couldn't help but ask, "Since there is this method, can Shen Tu Ya also absorb this energy?" ”

"No, because this kind of energy is unstable and generally negative energy, if Shen Tuya absorbs this energy, it is likely to be affected by negative energy, and eventually become bloodthirsty monsters, in fact, many wandering Gu spirits without a master have become very terrifying monsters due to the long-term absorption of this energy, which is why most of the ordinary people will be scared half to death when they encounter this kind of ancient spirit, and some of them will even attack ordinary people, trying to kill ordinary people to obtain the energy to exist." Master Sonomoto said.

It was the first time Tang Yao had heard of this kind of thing, and he secretly sighed in his heart that he still knew too little about the things in the circle.

"Then you mean to let me hunt this wandering ancient spirit, and then provide the energy after their shattering to Shen Tu Ya, but I still have a problem, first, this kind of ancient spirit should be difficult to deal with, and second, since they are ancient spirits that absorb negative energy and survive, then after their energy is supplied to Shen Tu Ya, won't Shen Tu Ya become a monster if they absorb it?" Tang Yao asked.

The old army sighed and said: "You kid is really stupid, I usually see that you are very smart, how can you be so stupid at this time, this kind of ancient spirit is definitely not easy to deal with, but they have no master after all, you and Shen Tu Ya are two to one, can't you take it, in addition, don't you have obsidian, the energy of these ancient spirits after breaking into the obsidian will be transformed into pure energy that can be absorbed by Shen Tu Ya, but this transformation will lose part of the energy, and the obsidian can't directly absorb the energy of human beings after death, That's the function of obsidian, but obsidian can absorb the energy of the ancient spirit that has just been shattered, do you understand now? ”

Tang Yao nodded, he basically figured it out, and after thinking about it, he asked, "I have one last question, where can I find those wandering ancient spirits?" ”

At nine o'clock in the evening, Tang Yao had been practicing all day, and now he was in a state of back pain, but he was still taken out by the old army, and the old army didn't know where to get a tattered battery car, and after driving Tang Yao out of the botanical garden, he did not go in the direction of the city, but went to the farther urban and rural junction.

"Where are we going, Brother Jun?" Tang Yao asked.

"Take you to meet the wandering ancient spirits, generally speaking, this kind of wandering ancient spirits are unlikely to appear in the urban area, they will also protect themselves, the urban area is full of people and will be found and even destroyed by other illusionists, so they are basically gathered in the urban-rural junction with few people, and if someone dies nearby, these ancient spirits will gather and hide in the place of the dead, I recently heard that an old couple in a nearby village has recently died, and now I just go over to see if I can meet this kind of wandering ancient spirit." Brother Jun said.
