Ning Xin also understood Long Yin's plan better, nodded and warned: "You have to be careful, the old man of Nine Swords is still hiding in secret, no one knows when he will appear."

"No problem!"

Long Yin smiled and shook his head.

When he returns to the Fourth Immortal Academy, he will be ready to practice the secret soul-quenching technique.

And after the soul-quenching secret method is successfully practiced, the attainments in soul power will definitely increase again.

If he really faces the Nine Swords Old Man at that time, he can completely use his powerful soul power to deal with the Nine Swords Old Man.

If he really couldn't do anything, he could completely sacrifice his soul power and kill the Nine Swords Old Man in one fell swoop.

"Anyway, it's your best to be careful!"

Ning Xin said seriously, "I will take the others back to Manwang City now, and I will manage Manwang City as our true root.

No matter what issues arise, we have a place to stay.”

The current Man King City is getting stronger and stronger.

Moreover, she is also training her subordinates in the Man King City and setting up some defensive measures in the Man King City.

In the future, whoever wants to take action against Man King City will discover how terrifying Man King City is.

Long Yin nodded slightly, thought for a moment, and said to Ning Xin secretly: "I will give you ten thousand spirit stones, and then let Shalang go to the Barbarian King City to build a large formation that belongs to us.

Inform Mo Wen and cooperate with Sha Lang to mobilize everything in Manwang City to arrange manpower.

Combine all the buildings in Manwang City.

Don’t let too many people know about this matter.”

Barbarian King City itself is a bit weird. The only thing it lacks is the lack of aura.

However, with the spirit stones, formations can also be set up in the Barbarian King's City.

Ning Xin nodded slightly and replied with the same soul seed: "I will make reasonable use of all the magic weapons in the treasure house and won't let too many people know about it."

Long Yin gave the spirit stone to Ning Xin, then went back to find Sha Lang. After telling Sha Lang his request, he continued: "If the spirit stone is not enough, you can ask me for it.

However, the formation of Barbarian King City must be capable of resisting masters."

"Don't worry, brother, after I carefully survey the Man King City, I will prepare a suitable formation in the Man King City."

Shalang nodded.

After having the spirit stone, the defense of the formation on the Crescent Lake will become very powerful even without his presence.

And with that group of brothers controlling the formation, there is no problem at all.

Now, of course, he is going to set up the formation of Barbarian King City.

After Long Yin watched Ning Xin leave with her people, he also took Yun Xi to the Fourth Immortal Academy.

After more than a month of latent cultivation, the students of the Fourth Immortal Academy have indeed accumulated many cultivation problems.

Unfortunately, there are no other teachers in the Fourth Immortal Academy, so no one can answer their questions.

Now that Long Yin is back, all the students are very excited and come to Long Yin to solve their doubts.

Facing so many students' problems, Long Yin also had some headaches.

Although he had gained the experience of practicing the Heavenly Thunder Technique, and even obtained the training memories of several great monks, the problems encountered by each of them were all kinds of strange.

Especially since Long Yin himself was not an immortal monk, and Yun Xi was not a complete immortal monk, Long Yin was somewhat unable to answer the questions raised by the soldiers of the Fourth Immortal Academy.

However, even if he can't answer, can't he find someone else?

Each of the eleven golden elixir stages in Lingxiao Pavilion turned out to be a cultivation level above the integration stage, and each of them was a person who was called the ancestor of the sect.

He asked these questions to the group of people in Lingxiao Pavilion, and it was not difficult at all to get the answers.

Even if they use different techniques, a group of great monks in the integration stage can't guide a group of immortal apprentices in the Qi Condensation stage and Qi training stage?

In other words, although there is only one teacher in the Fourth Immortal Academy, it is equivalent to the joint teaching of more than a dozen great monks in the integration stage.

And Long Yin is like an "encyclopedia", facing problems from all the colleges of the Fourth Immortal Academy, and will not reject anyone who comes.

This level of erudition shocked everyone in the Fourth Immortal Academy.

At this moment, Zhang Chaohe and others finally understood why they wanted this young man to be their dean.

It's really a vast knowledge, and the knowledge is terrible.

For half a month, all the questions of all the colleges in the Fourth Immortal Academy were answered.

Every student has found a suitable path for them. Everyone is practicing with concentration, and their strength is also improving by leaps and bounds.

And Long Yin's behavior made the group of people in Lingxiao Pavilion extremely painful.

They couldn't figure it out at all. Duanmuhai had a funny brain?

Actually asking them basic questions about immortality?

Moreover, after bombing them for half a month, they were really helpless.

Fortunately, half a month later, the bombardment of questions finally stopped, and everyone finally felt at ease.

And Long Yin, after helping the colleges of the Fourth Immortal Academy to answer the questions, he was relieved.

It is still somewhat difficult to teach three thousand students.

Of course, now that everyone's problems have been solved, he can sit down and practice hard.

Asking Yun Xi to protect him, he began to practice the secret soul-quenching technique.

At this time, in Long Yin's soul space, the entire soul reached a terrifying height of three feet, four or five feet.

However, when Long Yin started to use the soul-tempering secret method, Long Yin immediately discovered that there were actually a lot of gaps between the tall souls.

It is these gaps that lead to the "puffiness" of the soul.

What he has to do now is to close those gaps and try to make his soul as tight as possible.

When Long Yin activated the soul-quenching secret technique, the soul, which was more than three feet tall, quickly collapsed. The soul became purer and more compact.

The soul, which was originally over three feet tall, shrunk to just over ten feet tall when the secret soul-quenching method was used for the first time.

However, this was far from meeting the requirements of the soul-quenching secret method. Long Yin ran the soul-quenching secret method for the second time, and the soul that was more than one foot tall was once again shrunk to more than seven feet tall.

When the soul-quenching secret method was used for the third time, the soul shrank to about four feet, and there was no way to shrink it anymore.

Although the height of the soul is only about four feet, both the soul's attack power and the soul's defense power have become extremely terrifying.

Long Yin's mind moved, and his soul left the soul space and stood in broad daylight.

He could clearly feel the terrible evil spirit and strong wind blowing through the soul's body between heaven and earth. However, this terrible evil spirit and strong wind were just like the body of an ordinary person facing the wind and sand, and they did not have much lethality.

.

In other words, if necessary, his main soul can appear between heaven and earth.
