Desperate Night

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

He waited for a while and got a small pyroxene with a brand new rune.

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

‘The new rune combines the enhancement rune and the vortex rune, not a simple merger. The position and order of the internal symbols have changed. But the material of the pyroxene has not changed, it is still ordinary pyroxene. ’

Take out the enhanced detector, put it next to the pyroxene and press it.

Beep.

The value appears on the LCD screen of the detector: -7.221.

“No different from before the test.” Yu Hong frowned slightly. Before taking out this pyroxene, he had tested the data, that is, this data fluctuates up and down.

The red value of ordinary pyroxene is actually very small, mainly depending on the size.

And ordinary pyroxene, after being mined, will slowly break into pieces of similar size over time.

‘Perhaps the vortex rune itself does not work immediately, and it may take time to ferment.’ Yu Hong took out a pen and paper and made another record.

The white paper now recorded a lot of previous attempts. Using the black seal, he had ruled out many possible directions.

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

He quickly took a small piece of pyroxene and drew a vortex rune on it with a charcoal pencil.

Then he used the red value detector to test it again and recorded the data.

The result was still useless, without any change.

Yu Hong was not discouraged and changed to other things as the carrier of the vortex rune.

He just tested it with water grinding little by little.

The sky gradually began to darken again.

“Huh? Why is it getting dark so fast?” Yu Hong came back to his senses from the experiment and looked at the door window.

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

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

Yu Hong studied it and found the switch under the side, and turned it on with a click.

Hiss.

Suddenly, a clear electric current noise came out from the speaker.

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

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

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

"I don't agree. We have come through the most difficult times together, and now it's coming."

Several people seemed to have a dispute on the communicator, and Lao Li's voice was among them.

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

Yu Hong reached out and patted the communicator, making a popping noise.

The noise was very loud and immediately attracted the attention of the other side.

"Lao Li? Can you hear it?" He asked in a deep voice.

"Well, it's very clear. Is the signal so good on your side?" Li Runshan was a little surprised. Obviously he didn't know the gold content of the black seal products.

"It's okay, to make a long story short, I have something to consult you." Yu Hong said quickly. Although he and the other party agreed to open the communication at a fixed time every day, the electricity used for communication cannot be wasted. If there is no communication, he will choose to turn it off to save power and wait until the next day.

This function is actually very inconvenient and backward. Yu Hong really wants to complain why this thing can't be made like a phone, with a ringtone or vibration to remind, and both phones must be turned on to contact.

"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 to be useless. I don't know if you have any research on this?" Yu Hong asked his doubts bluntly.

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

"The one you mentioned has indeed been studied. To be precise, there are not only these two runes in the ruins, but also several other runes that you have not seen and have not appeared on the market. But there is actually only one that has been studied and found to be effective. It is the pyroxene enhancement rune we use." Lao Li answered quickly.

"Since it is useless, why is it painted on the stone wall of the ruins?" Yu Hong frowned.

"I don't know about this. Maybe scholars who study the ruins will know something, but when I just contacted the superiors, I found that the previous anti-interference communication is now also strongly interfered, and the signal is quite unstable. I suspect that the changes in the external environment have also greatly affected the communication." Li Runshan's tone was full of worry.

"Anyway, be prepared for a protracted war first." Yu Hong said.

"Okay, no more talking, it's getting dark, I hope there won't be a blood tide tonight." Li Runshan said.

Yu Hong responded, and the two disconnected.

Huh.

He let out a long breath.

'Has the communication at the post office also been affected? What if we lose contact with the higher-ups?’

A trace of worry flashed in his eyes.

Without contact, the supply team may not come often. If we don’t improve the strength of the field now, the supply team may 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 gate strength may not be enough to deal 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 avoid moisture causing mold. We also need a training space. We also need a testing laboratory. It is best to set aside as many cabins as possible at one time 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 first. 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 wave tonight, just quiet darkness.

There is no moonlight in the sky, the moon is covered 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 was now full of energy. He simply cooked some protein soup and started practicing after a meal.

After concentrating on training for three hours in one breath 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 Yu Hong's Dantian.

These particles are far 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 touched his abdomen gently and found that the body temperature there was slightly cold, as if it had just been exposed to ice, and it was bone-chilling.

And inside his abdomen, he could clearly feel that a new piece of cold inner energy 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 stable enough.

Now that his inner energy was building up 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. The effect is quite extensive.

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.

'etc! Since the wall can be strengthened as a whole and the formation can be strengthened as a whole, why can't the safe house be strengthened? ? ’

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 by 5. Improve wall hardness and moisture-proof ability. ’

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

laugh.

A black line separated from the black seal and blended into the ground.

Then there's the waiting.

One second.

Two seconds.

Three seconds.

Five seconds.

Finally, a cold mechanical voice sounded in his ears.

‘Do you want to strengthen the entire safe house? ’

At the same time, huge black countdown numbers appeared on the ground at Yu Hong's feet.

‘11:07 on the 24th. ’

‘It really works! ! ’ Yu Hong opened his eyes wide and suddenly became energetic.

He knew exactly what this meant. This means that in the future expansion and renovation of the safe house, he does not need to learn techniques or find people for help. He only needs to rely on the continuous synthesis and strengthening of the black seal!

‘Since it’s possible to strengthen the entire safe house, then I can definitely strengthen each cabin separately! ’

Yu Hong was in high spirits and with joy, as if his mind had been opened. He quickly stood up, walked to the wall, stretched out his hand and pressed it gently against the wall.

‘Strengthen this cabin, direction: increase the number of connected cabins, the number is 1,. ’

Instead of adding five cabins at once, he added just one cabin this time. None of the other enhancements are needed, just to determine how much time it takes to strengthen the cabin.

Soon, black lines flowed out, and a countdown appeared on the wall.

‘11:02 on the 4th. ’

‘Just over four days! This is much faster than digging it myself! ’ Yu Hong’s heart was shocked, and his face showed joy.

Although his strength and physique have greatly improved now, chiseling rocks is much more difficult than digging soil. So even with his current strength, it would be impossible to dig out a decent cabin in four days.

'The key is that after the black seal is strengthened, it is likely that everything was perfected for me. The flatness of the wall, the integrity of the entire cabin, and the beauty are much better than what I could do myself. ’
