Mortal blood!

"The Supreme God Refining Technique"!

This is the untransmitted secret technique used by true immortals in the ancient true immortal world to practice their spiritual thoughts.

It is said that in the ancient world of immortal cultivation, there was a powerful race that specialized in cultivating spiritual thoughts.

Fighting with the immortal cultivators of the same realm, the immortal cultivators who practice spiritual thoughts can almost completely crush the immortal cultivators of the same realm.

Lin Fan really didn't expect that this secret technique, which existed in the ancient world of true immortals and was specifically used to cultivate spiritual thoughts, would fall into his hands so easily.

"It seems that this thing is probably made by Fang Chong."

Lin Fan looked happy.

Study the "Tai Shang Shen Lian Jue" carefully.

Although the golden seal script was difficult to read, Lin Fan took the trouble to read it.

If you don't understand anything, ask Shuhun for advice.

Even so, it took Lin Fan half a month to gain a general understanding of "The Supreme God's Refining Technique".

"It is indeed a secret technique in the ancient immortal world. Not to mention understanding it, even if it is a smooth reading, it is not an easy task."

Lin Fan secretly smiled bitterly.

But he didn't give up.

It took another half a year to fully comprehend the "Tai Shang Divine Refining Technique".

As for the subsequent practice, it became extremely painful.

Especially when Lin Fan practices the Mystic Dividing Technique in "The Supreme Divine Refining Technique", he needs to accurately divide his divine thoughts into countless strands.

This kind of precise and difficult control of spiritual thoughts is countless times more difficult than practicing spiritual consciousness stabbing.

Every day, Lin Fan had a splitting headache.

Even so, Lin Fan did not give up practicing the "Supreme God Refining Technique".

After persisting in pain time and time again, after several years, Lin Fan's spiritual thoughts became extremely powerful.

Moreover, as long as Lin Fan makes a thought, his spiritual thoughts can be divided into countless small parts at will.

This gives him a huge advantage when controlling Chaos Spiritual Treasures and so on.

Especially when controlling the iron-eating ant colony, it has reached the level of freedom.

Moreover, after these years of continuous practice, Lin Fan found that the length of time he could control the iron-eating ants had significantly increased.

"If it were in the past, if I controlled 50,000 iron-eating ants, I could only hold on for half a stick of incense at most, and my spiritual power would be exhausted."

"Now, I can hold on for one stick of incense."

"It's a pity that the "Tai Shang God Refining Technique" in my hand is just the second volume, the middle volume and the first volume of "The Supreme God Refining Technique". They have not been found yet."

Lin Fan sighed secretly, thinking about the harvest over the years, he looked satisfied.

The next moment, his mind moved, and his mind quickly looked at the iron-eating ants.

Today's iron-eating ant colonies can be divided into two types.

One is one that he uses mysterious spiritual fluid to accelerate hatching. The other type is naturally hatched iron-eating ants.

Lin Fan did not deliberately feed the iron-eating ants that hatched naturally with anything rich in spiritual energy.

Let them grow on their own.

For those iron-eating ants that use mysterious spiritual liquid to accelerate their hatching, Lin Fan provides some sweet spring dew and mysterious spiritual liquid every day to accelerate their development.

It is precisely because of this that these deliberately cultivated iron-eating ants grow at an alarming rate.

Today, there are more than 100,000 semi-mature iron-eating ants.

In addition to this, there are ten thousand fully mature iron-eating ants.

According to Lin Fan's speculation, these mature iron-eating ants will be able to lay iron-eating ant eggs and hatch new iron-eating ants in a few years.

"Iron-eating ants are a powerful killer that I have cultivated over the years. Moreover, with their numerical advantage, they can easily deal with ordinary Mahayana cultivators."

"However, although the iron-eating ants are powerful in combat, unfortunately they are not very fast. Therefore, if you encounter a Mahayana cultivator who is good at speed, you still cannot kill them smoothly with the iron-eating ants alone."

Lin Fan thought secretly, trying to find a way to solve this problem.

Unfortunately, after Lin Fan thought for a long time, there was no good way to solve this shortcoming.

However, Lin Fan did not dwell on this matter.

With a thought, I contacted Xiao Huo and Xiao Jin.

They were originally a pair of iron-eating ants brought by Lin Fan from the lower plane.

After these years of vigorous training, to Lin Fan's disappointment, Xiao Huo and Xiao Jin always stayed at the state of great fortune in the late stage of integration.

Now, he has successfully advanced to the late Mahayana stage of Dzogchen.

The level of Xiao Huo and Xiao Jin is too low, and their help in his battle is not as good as before.

If it weren't for the fact that Xiao Huo and Xiao Jin had been with him all these years, Lin Fan would have really wanted them to fend for themselves.

"I've met the master!"

Xiao Huo and Xiao Jin said in unison.

Lin Fan nodded and looked at Xiao Huo and Xiao Jin.

Seeing that the two of them were still stuck at a bottleneck and unable to break through, they immediately frowned.

"You two have enjoyed a lot of sweet spring dew over the years, but you have never been able to break through the realm. It seems that what you have encountered is not a bottleneck problem, but the limitations of the bloodline itself."

"Solving this problem will require you to pay a huge price."

"Over the years, you have accompanied me through countless crises. I am also grateful for your efforts."

"However, I have now advanced to the late Mahayana stage. I'm afraid it won't be long before I reach the Tribulation Stage again."

"If you stay with me, the dangers you will encounter will become greater and greater. Therefore, I plan to give you a new way out."

Lin Fan looked indifferent.

When Xiao Huo and Xiao Jin heard this, their expressions suddenly changed slightly.

"Master, we are still willing to stay with you."

"Master, although our role in your life has not been as good as before, our loyalty to you is known to all."

Xiaohuo and Xiaojin hurriedly explained.

Lin Fan burst into laughter when he saw this.

"Why are you panicking? I'm not a good person, but I'm definitely not a heartless person. When I say I'll find a new way out for you, I'm not really going to drive you away. I'm really planning for you."

At this point, Lin Fan's expression became extremely solemn.

"Over the years, I have let you follow me, and I have provided you with many natural treasures. And you have also done a lot for me. We owe each other nothing."

"But, we are destined to be master and servant after all."

"So, my plan is to let you follow Lan'er temporarily. When she advances to the middle stage of the Mahayana, you will stay in the Ancient Holy City and become the human sacrifice of the Ancient Holy City."

"In this way, you will have a place to stay. The cultivation resources can also be provided by the Ancient Holy City."

After Lin Fan finished speaking, he quietly waited for Xiaohuo and Xiaojin to make a decision.

The two were silent for a long time, looking at Lin Fan and nodded.

"Thank you for thinking about us, Master. At present, this proposal of the Master is indeed the best destination for us."

"Well, in this case, I will cancel the master-servant agreement in your body now."

"Then, let Lan'er place the master-servant agreement restriction in your body. From now on, you will protect Lan'er!"

Lin Fan waved his hand, and the master-servant restriction in Xiaohuo and Xiaojin disappeared instantly.

Afterwards, Lin Fan took them to find Lan Lan, and told her his idea. Lan Lan was overjoyed.

"Husband, Xiaohuo and Xiaojin are your spiritual pets. Although they are only in the late stage of the great perfection of the fusion, their combat power is really extraordinary."

"Although I have broken through to the Mahayana stage, my combat power is not that outstanding. With the help of Xiaohuo and Xiaojin, I will be much safer in the future."

Lin Fan smiled and nodded when he heard it.

"In that case, let Xiaohuo and Xiaojin follow you for the time being. When you break through to the middle stage of the Mahayana, let Xiaohuo and Xiaojin settle down in the ancient holy city. They have followed me for so many years, and I can't treat them badly."

"Husband, don't worry, I will naturally not let you break your promise."

After Lan Lan finished speaking, she put a ban on Xiaohuo and Xiaojin in front of Lin Fan, letting them work for her.

After dealing with Xiaohuo and Xiaojin, Lin Fan was planning to continue practicing the "Taishang Refining Spirit Art" in seclusion while there was still time, when Cuihong suddenly appeared in front of him.

"Master, there is a late-stage cultivator outside the cave who wants to see you. He said he is the Heavenly Patrol Saint Emperor."

Lin Fan looked surprised.

The Heavenly Patrol Saint Emperor is in charge of the Heavenly Patrol Saint City. If there is no urgent matter, he will never step out of the Heavenly Patrol Saint City.

Now, the sudden visit of the Heavenly Patrol Saint Emperor made Lin Fan feel a little uneasy.

"Did something big happen in the Heavenly Patrol Saint City?"

Lin Fan frowned slightly and said quickly: "Quickly ask the Heavenly Patrol Saint Emperor to come to see me."
