Everyone chose to wait and see, although everyone knew that Lin Feng was injured and should not move, but everyone did not move, because they knew that this was what Lin Feng should kneel and must kneel, and the panther was also very excited in his heart, the emperor-level master, if only he could have one at any time.

Lin Feng kowtowed to Xu Lao three times without sounding, but he was attentive, Xu Lao stretched out his hands to help him up, and laughed: "From today onwards, Lao Tzu also has an apprentice, and his qualifications are still so good, hmph, let those old guys envy them when I go back!"

Everyone was stunned: Even if you receive an apprentice with unqualified qualifications, you don't need to be so happy, even if you are happy, don't show whether it's good or not, just be happy in your heart.

When Lin Feng heard this, he chuckled in his heart: Could it be that I just escaped, and now I have entered the den of thieves again?

If you were an ordinary person, you would definitely not hear the meaning of this sentence, but which of the few people present was not a shrewd person?

As long as you analyze carefully, you can roughly draw several conclusions, first: Xu Lao said that he also has apprentices, the key is the word 'also', under what circumstances, will he say the word 'also'? Generally, when he has nothing and others have it, until he has it, the word 'also' is used, or if someone else has done something and then he has done the same thing, he will also use this word.

With such an analysis, the first point is clear, which shows that Xu Lao has never accepted apprentices before, and he doesn't even have experience in teaching apprentices. In this way, guiding Lin Feng's cultivation has become a big problem, although Xu Lao's cultivation is unfathomable, but no matter how capable he is, there will be the possibility of making mistakes, not to mention that he is an old man who has no experience?

The second point: he said to go back and make those old guys envious, here' The old guy must be the rest of the elders of the Xu family, which means that the rest of the elders of the Xu family usually show off how talented their apprentices are in front of him whenever they have time, and Xu Lao has accepted Lin Feng now, so he will definitely use the same method to show off when he goes back, so that there will be less time to teach Lin Feng, because he has to take care of showing off, then he will ignore the guidance of Lin Feng's cultivation, and the focus is not on Lin Feng, no wonder he feels that he has entered a den of thieves.

"Don't worry, I'll remind Elder Xu when I go back. Xu Zihao said to Lin Feng and Lin Tianlong.

......

In the afternoon, Lin Feng was already fully recovered, and he was still seriously injured and dying in the morning, but now he was alive and well, for this, the rest of the people felt the power of this vitality grass, not only could they continue their lives, but even seriously injured and dying people could recover them to normal in half a day.

Not long after Lin Feng woke up, the masterminds of the various forces in the Phantom City all came to visit, and the meaning conveyed by the visitors was all roughly the same: they were willing to build the Phantom City together with the Wolf Tooth Mercenary Group as the leader.

Then, Lin Feng sent people out to mobilize the manpower and material resources that could be mobilized to repair the houses that had been damaged by the fighting in the past few days. At the same time, work began on the renovation of the walls and gates.

Rebuilding the wall and city gate was Lin Tianlong's idea, because in a few days they would be enemies of almost all the large forces in the Southern Regions, and the weak city wall was still so weak, I am afraid that it would not be long before the wolf's teeth would be destroyed.

Lin Tianlong proposed that Xu Lao arrange a defensive formation in the Phantom City, so that it could envelop the entire Phantom City, as long as there was an invasion of outsiders, it would be able to protect the Phantom City.

Xu Lao also readily agreed, if Lin Tianlong wants to rise, he must have his own power, and if he returns to Zhongzhou, he will take Lin Feng away, and the remaining Phantom City must also be led by someone, then, this person must be Lin Tianlong.

Because apart from him, there is no better candidate in the Phantom City.

Then, after a busy hour, a core formation the size of a house appeared in front of everyone.

"Old Xu?" Lin Tianlong looked at the huge core formation in front of him in a daze.

"Hmm, what's wrong?" asked Elder Xu.

"Isn't this core formation too big, if there is a strong person disguised to enter the city, wouldn't it be easy to find and destroy it. Lin Tianlong said in a condensed voice, and at the same time, he was also thinking of a solution in his heart, he couldn't let people move his hands to arrange one again.

"Ugh. Tianlong, it's not that I don't want to make it small, in fact, my cultivation is limited, this formation is called the core of guardianship, and the arranger must be above the emperor level at the very least, this is still the simplest requirement, and the second one also needs a person with strong divine thoughts to successfully arrange it, and cultivation and divine thoughts are also indispensable, and the size of the core formation also determines the strength of the defense, the smaller the stronger, and vice versa. This is also closely related to the person who sets up the formation, and the size of the core formation depends on the cultivation of the person who sets the formation and the strength of the divine thought. ”

Xu Lao shook his head and smiled bitterly: "And I, my cultivation can be regarded as reaching the core of protection that can arrange more powerful defenses, but my divine thoughts are only worthy of the high level of the earth, if my divine thoughts can have a heavenly level, I can improve this core formation, hey!"

"Heaven level?" Lin Tianlong muttered, thinking to himself: My divine thoughts have also reached the heaven level, but I just don't know if I can cooperate with Xu Lao to arrange this guardian core?

Seeing Lin Tianlong's frowning appearance, Xu Lao was puzzled: "Boy, do you have a way?"

"Elder Xu, if there is a person whose divine thoughts have reached the heaven-level and you are an emperor-level cultivator, can you improve this core formation?" Lin Tianlong asked in a deep voice, if it is really possible, then what if it is exposed? Anyway, sooner or later, it will be known by others.

"According to what you say, you should be able to succeed, but where can you go to find people whose divine thoughts have reached the heaven-level? Looking at the entire Martial Spirit Continent, there are not many people whose divine thoughts have reached the heaven-level, not to mention that none of those people are old monsters who have lived for tens of thousands of years? It is even more difficult to invite them. After Xu Lao finished speaking, he thought back to what Lin Tianlong said, and it seemed that something was wrong.

By the way, according to him, wouldn't he have a candidate, and that man might not be far from here.

So he asked, "Could it be that you have chosen someone?"

"Hmm!!" Lin Tianlong nodded heavily.

"Tianlong, let me say it first, that person's divine thoughts must reach the heavenly level, even if he is at the peak of the earth-level like me, if he only has the earth-level divine thoughts and does not have emperor-level cultivation, I am afraid that he will be eaten to death by the formation. Seeing that Lin Tianlong was so cautious, Xu Lao also said some requirements.
