Desperate Night.

Chapter 173 Chapter 173 Strengthening
As time went by, Yu Hong kept adjusting and testing. He imitated the array symbols he drew and tried to strengthen them in combination with the black seal. Finally, on the fifteenth day, he got feedback that the black seal allowed for successful strengthening.

After fifteen days and two weeks, he had cultivated his internal energy to the sixth level of the third level of Thunder Kick. His progress was much faster than before.

During this period, apart from strengthening the nutritional paste once more, Heiyin did not use anything else and was cooperating with Yu Hong in the experiments the whole time.

Taking advantage of the Black Seal's ability to strengthen things that have a complete foundation, Yu Hong kept adjusting the simulated symbol pattern until he copied a piece of symbol details from the new Wind and Fire Soul-Slaying Formation, and finally got the Black Seal's approval.

A complete, basic airflow obstruction formation is thus obtained.

Inside the cave.

Yu Hong wiped the sweat from his forehead as he looked at the hand-drawn formation in front of him. Concentrating on drawing it, which also required consuming internal energy, was a very tiring task.

But fortunately, there were ready-made formations to learn from, and by adding tests bit by bit, I finally came up with a complete version.

'This version is definitely not the simplest, but the basic functions are met, which is enough for Black Seal to strengthen.'

He sat cross-legged on the floor of the basement, looking at the array patterns on the wooden board. Suddenly, his heart moved, and he took out the two trophies he had obtained from the wooden frame in the corner.

One is the ruby-like crystal on the mutant crow.

The other is the black jade bone from Hayato.

"Anyway, there's nothing fancy about it. The principle of strengthening the black seal is to use synthesis instead of multiple strengthening. Only by adding new things each time can you strengthen it twice. In this case, let's try these two."

He didn't know what these two things were used for, but he could just rely on the black seal to control the direction.

Yu Hong placed the two objects on the wooden board, picked them up together, walked out of the cave, and came to the wall of the inner courtyard.

Snapped.

He put the board on the ground, not caring if there was anyone around.

Anyway, no one else can see the black mark and the countdown for strengthening.

He put his hand on the ground, and his action at this moment looked like he was checking the quality of the soil.

The pyroxene grass on the ground in the inner courtyard has long since withered, and now it is covered with transplanted green wild vegetables. However, the sunlight is getting shorter and shorter, and I don’t know how long these wild vegetables can last.

Yu Hong put his hands on the ground.

'The Black Wind Slowdown Formation is strengthened. Direction: Fusion of the slowdown formation and the other two Black Disaster materials. Strengthen the slowdown effect on the Black Disaster.'

This time, he strengthened the formation to include the large formation, the wooden board he had drawn, and the two relics.

In order to reduce the construction work, Yu Hong directly carried out the black seal reinforcement. Although it would take more time, there was no need to dig out the foundation again and then restore it, which actually saved time.

The most important thing is that the reinforcement is only done underground, so there is no need to worry about being discovered.

'In fact, I can continue to strengthen the function of the Black Wind Defense Array, but the current array is too large, and strengthening it will definitely take a lot of time. I will strengthen the deceleration array alone, which should take less time, and I can also apply the deceleration array I have researched separately to other places.'

This was the path Yu Hong had envisioned at the beginning. He would learn new things from the reinforced products, add new things after understanding them, and then reinforce them again, perfecting the camp step by step.

The same is true for internal energy and now the formation is also true.

Heiyin gave feedback quickly.

The countdown time appears: 17:01.

Yu Hong breathed a sigh of relief, knowing that his guess was correct. It wouldn't take much time to simply strengthen one function.

Standing up, he took the wooden board of the deceleration formation and began to think about the combination of various formation symbols.

The symbols he currently masters include pyroxene array patterns, vortex array patterns, concealment symbols, and the current deceleration array patterns.

In the basement, Yu Hong looked at the four symbols on the paper and already had an idea in his mind.

The reason why he wasted so much time, preferring to leave the Black Seal empty without strengthening anything, and also cooperating with his own tests, drawing out a complete deceleration array bit by bit, was all for this moment.

'These four runes can already form a simple compound formation.'

Yu Hong pondered in his heart.

'The essence of the pyroxene rune is to strengthen the effectiveness of the pyroxene itself. So it should be called the strengthening rune.'

'The vortex itself is storage and release, and concealment is to hide the breath, reduce and stabilize the radiation activity, which can act as a safety valve.'

'The final deceleration can be used to control the energy flow rate, and then combined with the internal energy to draw the large pyroxene powder as a connecting conduction line.'

"In this way, the conditions for a basic self-created composite array structure are met."

Yu Hong was very excited. As long as he completed a basic composite structure, he could nest it repeatedly.

Looking at the four runes, he began to wonder which direction he should try first.

After a moment, he decided to set up a deceleration formation first.

'Using the vortex array as energy, absorbing and releasing energy, and then using it to slow down, finally hiding the array to stabilize the structure, eliminate breath fluctuations, and strengthen the runes to enhance the deceleration effect.'

Yu Hong simply tried drawing four types of runes on a board, connecting them with simple pyroxene graphite powder, and combining them in sequence.

Using the ready-made simulation structure of the Wind and Fire Soul-Slaying Formation.

Soon, more than an hour later.

A brand new array wooden board appeared in front of him.

The wooden board is the size of a washbasin. Once painted, it begins to rapidly absorb the surrounding red value and store it for later use as energy.

Yu Hong also made a structure that can be folded and opened, which can save toner.

'Then, just wait'

He put down the board with satisfaction and went to the first floor to eat something.

'If this succeeds, I can use the combination of array patterns to enhance other functions. For example, I can enhance the two corrosive abilities of black wind and black fire in the Wind and Fire Soul Slaughtering Array!'

Having tasted the sweetness, Yu Hong felt that he had finally found the correct way to open the black seal.

Study and absorb the strengthened things, summarize the experience and inspiration, add a little new things, and you can strengthen new and stronger things again.
In this way, you will master more and more abilities, becoming more and more flexible and able to cope with many complex environments. The things strengthened by the black seal will also become stronger and stronger, forming a virtuous cycle.

Just like he summarized his internal energy foundation based on the strengthening method, and then directly strengthened the internal energy Wuji Ningqi Jue, which in turn accelerated the Benlei Leg Technique.

Time passes slowly.

The sky gradually brightens, the night passes, and silence arrives during the only two hours of daylight in the day.

Yu Hong didn't sleep all night, trying out various combinations of runes. When daybreak came, he drank some water and lay down to rest for a while.

Inside the stone castle.

Old Li and Old Zhou got up and started preparing for the new day, moisturizing the breeding boxes, checking the temperature, adding humus soil, sorting out cockroach and lizard feces, etc.

At the same time, you should exercise and prepare breakfast.

As the fighting force besides Yu Hong, Lao Li and Lao Zhou have to practice fighting skills and simulate shooting every day.

The two discussed the types of black disasters encountered outside and how to best deal with them.

As we go about our daily lives.

Outside the camp, a group of black insects flew together and condensed into a black human figure.

It's the insect man.

It mechanically moved forward along the edge of the camp, getting closer and closer.

puff.

Soon, a black lizard in the corner spit out saliva, which stuck to the side of its cheek.

But this time, the spitting humiliation attack, which had always worked, did not cause the insect man to take any action.

It remained motionless and continued to move forward.

Walk slowly towards a corner of the camp.

Inside the cave.

Yu Hong sat up suddenly and looked intently at the insect man through the black lizard.

He did not rush out so as not to arouse the other party's desire to attack.

'In essence, the stone fort has hidden runes, and the aura fluctuations are hidden. In Black Disaster's eyes, what he sees should be just a strange camp with a little bit of living people's aura. As long as the things in the camp that disgust him are greater than the things that attract him, he can be expelled. Therefore, the camp must ensure that all living people do not go out. Increasing the aura of living people will increase the attraction.'

Keeping a close eye on the insect man, Yu Hong did not go out in person this time to lure the other party away.

He was also just trying to try out the specific power of the strengthened Wind and Fire Soul-Slaying Formation.

puff.

puff.

The bug man slowly approached the camp fence.

It should be where the eyes should be, looking into the camp.

One step, two steps
puff!
In an instant, its entire body turned into a swarm of insects, flying straight over the fence and rushing towards the stone fort.

But just as it flew into the fence.

The formation, which had doubled in size, took effect instantly.

A ball of transparent air spurted out from the ground and hit the swarm of insects transformed by the insect man.

The airflow was like a pillar, completely wrapping the insect man and continuously impacting it.

At the same time, black sparks appeared inside the Zerg, trying to ignite the Zerg-men.

Suddenly, the flying speed of the swarm of insects suddenly slowed down and became much slower.

But even so, the short distance of thirty meters to the outer courtyard was not enough for it to fly.

It was about to fly to the wall of the stone fortress.

Suddenly a figure rushed out from the inner courtyard and threw a radiation grenade at it.

Bang!
Seven thousand negative radiation exploded, but this was more insulting to the Zerg.

It was also attracted by the strong scent of living people, and turned sharply, rushing towards the figure.

But suddenly, the figure began to run around in circles in the outer courtyard at a speed no slower than it.

The insect people were not as fast as Yu Hong in open areas, and now with the obstruction of the formation, they were even slower.

So the two of them chased each other and quickly ran a circle.

Two laps followed.

Three laps.

four laps
The black sparks on the insect man's body turned into black flames, and layers of black insects were burned to death and fell down like sand.

As it circled around, it had already stayed in the formation for more than ten seconds.

Yu Hong ran, slowing down from time to time to wait for it.

He felt relieved when he saw that the insect man's body had obviously shrunk compared to before.

'It should have reached the damage limit of the formation now, 12,000 units of damage per second. Even if it is a bug man, with a total red value of more than 100,000 radiation, it can't withstand the burning speed of this speed.'

really.

Ran a few more laps.

The insect man was half the size of when he came in.

It was only about 1.4 meters tall at this time, like a dwarf. When it realized something was wrong, it immediately turned around and rushed out of the formation.

Seeing this, Yu Hong simply stopped and tried to lure the other party to continue chasing.

But this insect man obviously possessed a certain level of intelligence. Without even looking back, it still maintained its human form and rushed out of the camp, disappearing in the mist of the forest in the blink of an eye.

Yu Hong chased after him, stood in the yard outside the camp, and looked out.

He didn't dare to chase after him, because apart from the formation and props, he didn't dare to come into contact with the insect man in person.

Standing inside the fence, his face finally relaxed a little.

"The formation needs to be strengthened, but the damage is indeed very strong. Except for the fast-moving level 8 black disasters like the insect man, the rest of the black disasters are not worth mentioning to the camp."
