Chapter 91

The new research method requires the strengthening time of the black seal. Fortunately, after Yu Hong synthesized the vortex runes and pyroxene, the countdown was only a few minutes.

After waiting for a while, he got a small pyroxene with a brand new rune pattern.

Picking up the pyroxene, he observed the runes on the surface.

'The new rune combines the enhanced rune and the vortex rune. It is not a simple merger. The position and order of the internal symbols have changed. However, the material of the pyroxene has not changed, it is still ordinary pyroxene.'

He took out the enhanced detector, placed it next to the pyroxene and pressed it.

Di.

The value displayed on the detector LCD screen: -7.221.

"It's no different from before the test." Yu Hong frowned slightly. Before taking out the pyroxene, he had tested the data, which meant that the data fluctuated up and down.

The redness value of ordinary pyroxene is actually very small, mainly determined by its size.

Generally, after ordinary pyroxene is mined, it will slowly break into pieces of similar size over time.

'Perhaps the vortex rune pattern itself does not have an immediate effect, and it may take time to ferment.' Yu Hong took out a pen and paper and took notes again.

At this time, a large number of previous attempts had been recorded on the white paper. Using the black seal, he had eliminated many possible directions.

‘What if I use the vortex runes alone to draw?’ Yu Hong thought of another way.

He quickly took a small piece of pyroxene, picked up a charcoal pencil, and drew a swirling pattern on it.

Then use the red value detector to detect again and record the data.

But the result is still useless, no change.

Yu Hong was not discouraged and replaced it with other things as the carrier of the vortex runes.

He just tested the water grinder little by little.

It gradually started to get dark again.

"Huh? Why did it get dark so fast?" Yu Hong came back from the experiment and looked at the window of the door.

He took out the enhanced communicator, which turned into a small, boxy plastic box with four speakers around it.

There is a row of buttons and knobs on the top, with functions and numbers marked on one side respectively.

Yu Hong studied it, found the switch at the bottom of the side, and clicked it on.

hiss.

Suddenly a clear current noise came from the speaker.

But soon, the noise disappeared and was replaced by a faint voice.

".Four days, at most we will face it in four days."

"There are too many people, and there are still a lot of supplies. Reduce the number and drive them out."

"I don't agree. We have all gone through the most difficult times together, and now we are here."

Several people seemed to have an argument over the communicator, and Lao Li's voice was among them.

He seemed very calm and gave the maximum time that the existing supplies could support him, but the rest was not very clear.

Yu Hong reached out and patted the communicator, which made a clicking noise.

The noise was so loud that it immediately attracted the attention of the other party.

"Old Li? Can you hear me?" he asked in a deep voice.

"Well, it's very clear. Is the signal there so good?" Li Runshan was a little surprised. Apparently he didn't know the value of Heiyin's products.

"It's okay. To make a long story short, I have something to ask you here." Yu Hong said quickly. Although he had made an appointment with the other party to turn on communication at a fixed time every day, the power used for communication cannot be wasted. If there is nothing to communicate with, he will

Choose to turn off power saving and wait for the next day.

This function is actually very inconvenient and backward. Yu Hong wants to complain about why this thing can't be made like a phone, with ringtones or vibrations to remind people, and they have to be turned on to contact each other.

"What's the matter?" Li Runshan was also very satisfied with the quality of the call.

"I went to the ruins cave and found another rune similar to the pyroxene rune, but this rune seems useless. I wonder if you have any research on this?" Yu Hong asked bluntly.

express your doubts.

He didn't believe that other people exploring the ruins would not study the swirling runes, so if he could get some clues from the post office, it would save him a lot of time and energy.

"You said that you have indeed studied it. To be precise, there are not only these two runes in the ruins, but also several other runes that you have never seen and have never appeared on the market. But after really researching it,

Actually, there is only one that works. It is the pyroxene we use to enhance the runes." Lao Li quickly answered.

"If it's useless, then why is it painted on the stone wall of the ruins?" Yu Hong frowned.

"I don't know about this. Maybe scholars who study ruins will know something. But when I just contacted the superiors, I found that the previous anti-interference communication was also subject to strong interference. The signal was quite unstable. I doubt the external environment.

Communication has also been greatly affected by the changes." Li Runshan said with a hint of worry in his tone.

"No matter what, first prepare for a protracted war." Yu Hong said.

"Okay, let's not talk anymore. It's getting dark soon. I hope there won't be a blood wave tonight." Li Runshan said.

Yu Hong responded and the two disconnected.

call.

He took a long breath.

‘Have the communications at the post office been affected? What if we lose contact with them?’

There was a trace of worry in his eyes.

Without contact, it is very likely that the supply team will not come often. If we do not increase the intensity in the current field, it is very likely that the supply team will not come again in the future.

'If the pyroxene grass outside can't dispel the blood tide, then I have to rely on the gate of my cave to resist it. But the current door strength is probably not enough to cope with the blood tide.'

After quickly assessing the possible dangers, Yu Hong decided to strengthen the door.

The mother and daughter in the yard outside will leave sooner or later, so don't pay attention to them, but if the supply team cannot come, they can only rely on themselves and be completely self-sufficient.

'To strengthen the door, you need to increase the volume of the safe house and leave space for storage and breeding. It is also best to separate washing and excretion separately to prevent moisture from causing mold. There is also a training space. A testing laboratory is also required.

It is best to leave as many cabins as possible at once to prepare for future expansion.'

After confirming the future plan, Yu Hong hand-drawn a very rough structural diagram of the underground cabin, and initially decided to develop five cabins. One of them should be as large as possible for indoor training experiments.

After deciding the location of each cabin, he looked outside.

It was completely dark outside the door, but there was no blood surge tonight, just quiet darkness.

There is no moonlight in the sky, the moon is blocked by clouds, and only the occasional starlight exposed between the clouds is the only source of light.

Outside the cave, the pyroxene grasses in the yard swayed slightly in the wind, emitting a soft and bright white halo.

Yu Hong took a nap during the day, and now he was very energetic. He simply cooked some protein soup, and after eating a meal, he started practicing.

After concentrating on training for three hours at a stretch and consuming as much physical energy as possible, Yu Hong was about to stop and prepare to rest, when he suddenly stopped at the last moment.

hiss.

A faint sound came from his abdomen.

A large number of strange particles unknown to the outside world are currently passing through the fat layer of the white skin, passing through the red muscle layer, and continuously drilling into the location of Hong Dantian.

These particles are much finer than sand and dust. They appear to be real objects, but they can easily pass through them, making them seem like illusions.

This strange state lasted for more than ten seconds and then slowly disappeared.

‘This is...!?’ Yu Hong gently touched his abdomen and found that the body temperature there was slightly cold, as if he had just been exposed to ice, and it was bone-chilling cold.

And inside his abdomen, he could clearly feel that a new, cold inner Qi had slowly appeared there.

‘The first inner energy of the second level has finally been developed!’ Yu Hong compared the descriptions of the heavy leg exercise and finally let out a sigh of relief.

Without inner energy in his body, although his physique has been greatly strengthened, he is still not steady enough.

Now that his inner energy had accumulated again, it gave him a great sense of security.

"Now that I'm full of energy, I'll start expanding the basement tomorrow!" He felt at ease again.

Inner Qi is not only a powerful trump card for battery life, it can also speed up the recovery of pyroxene grass and provide more energy for strengthening the black mark. It has a wide range of effects.

Having determined his plan for tomorrow, Yu Hong finished his work and prepared to go up and rest.

But at this moment, a flash of light flashed through his mind, causing him to stop and stand where he was.

‘Wait a minute! Since the wall can be strengthened as a whole and the formation can be strengthened as a whole, why can’t the safe house??’

Standing in the green light, the light in Yu Hong's eyes became more and more obvious.

He stood quietly for a moment, then suddenly squatted down and pressed one hand on the ground.

'Strengthen the entire safe house, direction: increase the number of cabins 5. Improve the hardness and moisture-proof capabilities of the walls.'

After giving the request silently in his mind, Yu Hong waited for Heiyin's feedback with deep anticipation.
