Gu Tiancheng didn't have much patience to grind with Gu Ling'er at this time, and he also made up his mind that if Gu Ling'er was still unwilling to cooperate, he would use the power of the soul contract to force Gu Ling'er to comply. As for Gu Ling'er's feelings, she can only make up for it later.

Unexpectedly, this time Gu Ling'er became a lot more "reasonable", and did not talk a lot crookedly, although he was still reluctant, he still cooperated to deliver a large amount of spiritual energy for Gu Tiancheng to make every effort to promote the growth of new spiritual sources.

With the blessing of this kind of spiritual energy regardless of the cost, the spiritual source has grown rapidly. In addition, Gu Tiancheng directly used the power of the divine realm of Allen's exercises, which was more like a downgrade cast, and the growth of the spiritual source was even faster.

In less than an hour, the spiritual source had already grown to the Holy Rank and began to transform the spiritual source into the spiritual core form.

According to the theory summarized by Kerry, Gu Tiancheng began to use the power of spiritual exercises, and then strengthened the introduction of his consciousness, in order to ensure that the new spiritual core was completely within the scope of his consciousness.

In addition to requiring Gu Tiancheng's full concentration and mental strength, this work also requires a large amount of spiritual energy support from Gu Ling'er.

This time, Gu Ling'er didn't let Gu Tiancheng urge, and she cooperated with the delivery of spiritual energy. This made Gu Tiancheng a little unaccustomed: When did Gu Ling'er become so obedient?

The work at hand is a delicate job, not only Gu Tiancheng himself has to do his best, but Kerry is also nervously calculating, guiding Gu Tiancheng to adjust the operation at any time.

This is the first time that Gu Tiancheng and Kerry have led the whole process of spiritual source generation from scratch to growth, and then to evolution into a spirit core, although Gu Tiancheng and Kerry feel that there are not many problems, but there is no practice, and no one knows whether the theory they have mastered is perfect and correct.

The first test mouse was himself, and Gu Tiancheng certainly didn't know the bottom of his heart. But fortunately, Gu Ling'er was there, and Gu Ling'er's situation when he first cultivated the soul technique manual made Gu Tiancheng deeply impressed. Gu Ling'er was able to automatically correct and improve the deficiencies or deficiencies in the notes, or even the wrong parts during the cultivation process, so as to quickly reach the realm of soul technique cultivation.

In this spiritual core test, if there is really any deficiency or fallacy in the theoretical knowledge mastered by Gu Tiancheng and Kai Rui, then the burden of correction and adjustment will completely fall on Gu Ling'er.

Thinking of this, Gu Tiancheng felt that he was too harsh on Gu Ling'er, and somewhat ignored Gu Ling'er's feelings.

Although Gu Ling'er is her own pet, she is not an ordinary pet. Gu Tiancheng must take care of Gu Ling'er's feelings and let Gu Ling'er follow him willingly.

Gu Tiancheng was still manipulating the process of the evolution of the spiritual source to the spiritual core, but he was forcibly distracted and said to Gu Ling'er: "This time you have spent a lot of spiritual energy. I want to thank you. Although you have learned from this, I still feel that I should express my gratitude to you. Otherwise, there will always be some difficulties in my heart. ”

Gu Ling'er's originally depressed mood suddenly became excited, "How do you want to thank me?"

Gu Tiancheng said: "What you like the most is spiritual energy, how about I compensate you for double your spiritual energy?"

Unexpectedly, the corners of Gu Ling'er's mouth twitched, and she said disdainfully: "I won't replenish the spiritual energy consumed?" Besides, spiritual energy is everywhere, I rarely give me the ones? If you want to thank me, you have to show sincerity, don't always think about fooling things." I'm not a kid anymore, it's not a popsicle, a candy can be beaten. ”

Gu Tiancheng really didn't expect Gu Ling'er to say this, and hurriedly asked: "You say this, must you have something you like?" Say it and see if I can satisfy you." "Weichang

Gu Ling'er suddenly became happy, "You can definitely do it." I want you to practice the Allen Exercises!"

Gu Tiancheng was surprised: "You want to practice the Allen Exercises? I haven't figured it out yet, how can I teach you?"

Gu Ling'er said: "I see that you and Kerry have studied very well, just teach me the part that you two understand." Even if there are some imperfections, I can fix them myself. ”

As soon as Gu Ling'er finished saying this, Gu Tiancheng only felt a buzzing in his head, and he had a feeling that his mouth was suddenly opened: Yes, he always suspected that Allen had done something to his exercises, but he never found it.

asked Kerry to help study Allen's exercises, but he has not been able to break through. After all, Kerry can't touch anything on his soul.

But Gu Ling'er is different, that fragmentary soul technique exercise notebook can help him become a master of soul skills in one fell swoop. Then this part of the Allen exercises that he has mastered may also be able to achieve Gu Ling'er.

Moreover, if Gu Ling'er can also repair and improve Allen's exercises, it will also be a huge gain for Gu Tiancheng himself. At least, Gu Tiancheng was able to deduce from this what was going on with the part of Allen's Exercises that he didn't know. Even if this part is added, he still can't master all the Allen exercises, at least, Gu Tiancheng can understand how to explore the unknown territory of the exercises according to this operation. Either way, it's a rare bonus.

Gu Tiancheng's heart shook violently, almost affecting the important work at hand. Gu Tiancheng was just angry, why didn't he think of this trick? I already knew that I could have taught it to Gu Ling'er a long time ago, and with the help of Gu Ling'er's psychic body to improve Allen's exercises.

"No problem!" Gu Tiancheng immediately agreed, "It turns out that you want to learn this, why didn't you say it earlier?"

Gu Ling'er shook her head: "It's useless to say it earlier, you didn't understand so deeply at that time, I can't learn it." But today you finally sorted out some of it, and I think it's feasible, at least I can cultivate. ”

"Okay," Gu Tiancheng responded very happily, "When I finish the matter of the spirit core, I will teach it to you immediately." ”

After reaching this "deal", Gu Tiancheng continued to obtain spiritual energy from Gu Ling'er with peace of mind and enrich the spiritual source. Finally, after another hour of hard work, the spiritual source finally changed, began to gradually condense into a nucleus, and independent consciousness began to appear, and even could interact with Gu Tiancheng.

Gu Tiancheng clearly sensed that that autonomous consciousness was his own, as if it was his second self, which was completely different from that of the old spirit core.

As if he had just given birth to a congenitally deficient baby, Gu Tiancheng hurriedly packed him and gave him to Gu Ling'er, for fear that he would suddenly die after staying here for a long time.

Gu Ling'er obviously didn't understand Gu Tiancheng's psychology, and wondered why Gu Tiancheng was so anxious to hand over the newly grown spirit core to himself.

Gu Tiancheng didn't bother to explain to Gu Ling'er, and continued to sit there to rest. Coincidentally, during Gu Tiancheng's rest, the old spirit core came out of the state of retreat.

The spirit core that has absorbed a sufficient amount of dragon soul power is already faintly human, although it looks very vague, but when you look closely, it is a dripping spirit core, which is very magical.
