The layout of the holy realm in the source realm is led by the Nine-level tower, with stars and densely spreading strongholds of varying sizes, forming one node after another, forming an innate formation of the universe and a forcibly intercepting one part of the source realm, forming a relatively stable and safe area.

Obviously, under such a layout, the Nine-level Tower of the Holy Realm is of course very important, but the strongholds standing at key nodes are also very important, and are the key to the gradual encroachment of the source realm.

Therefore, how to arrange these strongholds and how to design them has become a problem that the holy realm must overcome.

At this critical moment, the three masters and the Three Qing Tianzun were inspired by the lighthouse. After repeated calculations and research, the final design of the stronghold was based on the lighthouse.

It has to be said that this design is indeed suitable, because the function of the lighthouse is to point out the direction of the ships sailing above the boundless sea and illuminate a way home.

This adventure exploring the source world is also a ship sailing on the irritable ocean. The light on the lighthouse guides them successfully and illuminates the route home.

Therefore, using the lighthouse as the shape design base itself has certain meanings and implies Tao and reason.

However, this stronghold belongs to the layout of the holy realm outside. Its own significance is not only to point out the direction, but also shoulders certain defense and supervision effects, which is equivalent to a military fortress.

Coincidentally, the design of the lighthouse also meets this condition.

Don’t forget what is the most dangerous existence in the source world, the boundless darkness that falls in the night and the great horror hidden in the darkness.

The fortress in the lighthouse style carries a good burning object refined by the power of the world. Under the burning of raging flames, it illuminates a world, dispels darkness, and forms a pure land shrouded in darkness.

In this way, the lighthouse-shaped strongholds were formed one by one as time passed, guarding the nine-story towers, forming a huge innate Qiankun array. The current coverage has reached about 3,000 square kilometers, about one-third of the land area of ​​the Heavenly Dynasty.

However, the holy realm is obviously not satisfied with this in erosion of the source realm.

All because the Holy Realm has eroded the Source Realm for so long, and although it has eaten a large piece of land, it is a drop in the bucket for the huge Source Realm.

In addition, the malignant creatures in the source world are becoming more and more powerful, and have formed a certain scale and primitive civilization, which has seriously hindered the expansion of the holy realm, so that in nearly 100 million years, there are very few strongholds that have been successfully built.

This is why when Su Yang proposed a complete set of military reforms, the Holy Realm would attach so much importance to it, because it once again made them see hope for expansion and did not always stand still.

However, whether this military operation can really proceed smoothly is still an unknown number and remains to be tested.

Before this, what Su Yang had to do was to apply what he had learned before. Under the guidance of Han Zhenghai, Han Yan Squad and others, he would understand the source world more intuitively and deeply step by step.

It is obvious that eating a fat man in one bite is definitely not possible. The special chaos in the source world will make Su Yang crazy.

But it is not a solution to take it slowly, because Su Yang will not spend too much energy on this aspect for the time being. He still has a lot of things to do, so he is destined to explore the source world only once in a short time.

Therefore, in order to convince Su Yang, the three masters must make Su Yang truly realize the threat of the source world through only one exploration.

Therefore, Han Zhenghai, who was ordered in danger, shouldered a crucial responsibility.

Especially before setting off, the three masters deliberately had a long talk with Han Zhenghai, analyzed the many powerful relationships clearly, gave Han Zhenghai many secret treasures, and allowed him to act according to the opportunity. In this half-year exploration, he protected Su Yang and successfully persuaded Su Yang to hand over the cloned method, which was a flawless one.

Han Zhenghai also realized the key to the problem. After careful consideration, he should do this.

Han Zhenghai’s cleverness is his confession. He has no intention of hiding this matter from Su Yang. He bluntly told Su Yang the tasks assigned to him by the three masters.

Sometimes, some things are better than hiding them when they are said.

Especially people like Su Yang who hate others cheating him and harming him the most. Even if they have had a deep relationship in this regard, they still cannot be forgiven.

For example, the Evil Emperor had an enlightenment to Su Yang at the beginning, but his repeated use of Su Yang led to a breakdown in the relationship between the two sides. In the end, when the Evil Emperor was in trouble, Su Yang did not go to save him. He directly sealed more than ten thousand yuan in his hand before handing him to Buddha and Yuanshi, allowing them to decide the life and death of the Evil Emperor.

In other words, if the Evil Emperor was honest enough to Su Yang, rather than to take advantage of Su Yang, Su Yang would never ignore him after he was in trouble and would definitely try his best to help him reshape his body.

Obviously, Han Zhenghai's attitude towards this aspect is very positive. He treats Su Yang sincerely without hiding it, and has never had any intention of making use of it. He is grateful and rewards with all his strength.

Su Yang expressed his understanding of this. He didn't say anything at that time, but just hugged Han Zhenghai.

If you treat me sincerely, I will return with sincerity.

This is the attitude Su Yang expressed. I will treat you as much as you treat me. No one in this world is a fool. I know who is right and who is wrong.

Han Zhenghai is not only honest in his attitude, but also open and honest in his actions and actions.

Starting from leaving the Nine-Level Tower of the Holy Realm, Han Zhenghai explained and guided him all the way. Although it was all the knowledge mentioned in the previous book, it was even more impressive after combining it with the actual situation.

Now, Han Zhenghai continued to fulfill his agreement with Su Yang, holding the laws of the three masters, and with Han Yan's assistance, the three of them climbed up the steps with Su Yang and soon arrived at the top of the stronghold.

The stronghold is a lighthouse-shaped design, so at the top is a huge room. The room is made of special crystals, transparent inside and outside, and passes through special sections to maximize the release of the light source.

So when Su Yang entered the room of the lighthouse, the first thing he saw was a large brazier with a diameter of more than meter. There was a burning substance made of the power of the world in the brazier, which was burning, releasing an extremely warm light and tearing away the darkness.

But this is not the Nine-level Tower of the Holy Realm, so although the flames burned here are mainly based on the power of the world, they are rootless things. They need to be filled inward for a fixed time to continue burning well.

In addition, it is not like the Ninth Level Tower of the Holy Realm that directly extracts the power of the world to burn, so the intensity of the combustion is slightly inferior. It can only protect a certain area and barely ensure that the stronghold is not eroded by darkness.

For this reason, after Su Yang arrived at the lighthouse room, he felt the warmth of the burning flames, and then he saw the extremely rich darkness like a dark cloud pressing on his head, making people feel particularly heavy.

To describe it in one sentence, that is, this place is particularly close to the darkness.

Because it is particularly close to the darkness, the chaotic and crazy power has intuitively influenced this place. Even if Su Yang is already trying hard to restrain himself, the serene voice cannot be suppressed, and it is everywhere and directly transmitted to the mind.

In order to block the interference of these sounds, Su Yang directly closed his hearing, but the noise still did not disappear and echoed in his heart, making Su Yang more and more irritable.

"For you!" Han Zhenghai took out the heart crystal again and handed it to Su Yang.

Su Yang, who tried his best to restrain himself, slowly took the heart crystal, took a deep breath, and began to inject his mind and make a mental judgment.

The moderate yellow pollution soon appeared in the heart crystal, and even mixed with red light, indicating that Su Yang is gradually moving towards a dangerous and severe pollution state, and is getting closer and closer to going crazy.

Seeing this scene, Su Yang's face immediately changed slightly and his expression was serious.

Han Zhenghai didn't talk nonsense, and Han Yan took out a piece of heart crystal and held it in his hands. The heart crystal in the hands of both of them also showed a faint blue color, indicating a mild pollution state.

Su Yang's pupils condensed slightly, and he obviously realized something.

Han Zhenghai had no intention of explaining at this time, and waved his hand and said, "Let's go, let's go out first."

After saying that, Han Zhenghai and Han Yan protected Su Yang and left the crystal of the lighthouse. Until they closed the thick stone gate, the serene noise slowly disappeared without looking directly at the darkness.

Huh~!

Su Yang immediately looked like a fish that was lacking in oxygen, gasping for breath. The experience he had just had really made him unforgettable for his life. His consciousness was a little blurred and his heart was extremely irritated. It seemed that he fell into the deep seabed. The endless pressure was almost squeezed into a pool of meat paste.

After a long time, Su Yang slowly came over. The heart crystal in his hand gradually returned to normal, but it was still flooded with dark blue, telling Su Yang that he was still in a mild state of pollution.

"What happened just now?" Su Yang asked dryly. At this time, he was surprised to find that his voice was particularly hoarse, as if he had been dehydrated for a long time, and his throat was a little painful.

It's just a while, how could this happen?

Su Yang was still scared, and there was a deep sense of disbelief in his eyes. All this exceeded his expectations.

Yes, with Su Yang's concentration, he believed that even if he could not adapt to the chaos and madness of the source world quickly, he would not be so unbearable and would fall into a state of madness.

In this regard, Han Zhenghai explained: "Your physique, known as the mad body in the holy realm, is most susceptible to chaos and madness, especially during the arrival of darkness. The closer we are to darkness, the more severe the impact it will be. Now we are in the safe area, and this situation is relatively controllable. If we leave the safe area and we have no stronghold to rely on, are you sure you can bear it?"

When Su Yang heard this, his pupils immediately trembled slightly.

Han Yan suddenly understood something and said in shock: "What?! Mr. Su is a crazy physique? No one, what can you do with such a physical fitness? You can explore the source world! As soon as tomorrow dawn, you will immediately return to the Ninth Tower of the Holy Realm. Otherwise, once you leave the safe area, the chance of going crazy is uncontrollable!"

Han Zhenghai raised his hand to stop the irritable Han Yan, staring at Su Yang quietly, waiting for an answer.

Su Yang did not answer immediately, but sat down cross-legged, visualizing the thunder of heaven in his mind, suppressing all distracting thoughts, keeping the mind and mind, abide by one's own body, and not being invaded by external evil.

The Heavenly Dao Tribulation Thunder is worthy of being the most powerful and strong in heaven and earth that kills evil spirits. Under Su Yang's full visualization, the evil thoughts in his heart were immediately completely suppressed, erased layer by layer until they disappeared.

After a while, the heart crystal in Su Yang's hand returned to normal again, and was flawless.

Then, when Su Yang opened his eyes again, his eyes were transparent, clean and pure, without a trace of madness or irritability, and he returned to normal.

At this time, the body's functions revived, and the vitality was awakened under the baptism of thunder, and Su Yang returned to normal in the blink of an eye.

With a long sigh, Su Yang smiled and said, "Okay, let's continue."

"Continue? Are you really crazy or fake crazy? I can't allow you to continue making trouble like this anymore!" Han Yan stopped him immediately. He did not forget his responsibilities and was unwilling to let Su Yang suffer any danger.

Su Yang smiled calmly, ignored Han Yan, and just looked at Han Zhenghai quietly.
