Chapter 5 The alarm bells are ringing, there will be a high-intensity attack at the end of the month
"Puff!"
The Heavenly Sword swept out violently, directly chopping off the front limbs of the mantis that were attacking with lightning, and then it was as powerful as a bamboo, and it slashed at the mantis man.
This sword was as powerful as a bamboo, splitting the mantis man in half!
[K.O!]
[Earth human XX wins, it took 1.6 seconds. ]
Instant kill!
But the difference is that the target of the instant kill this time is the mantis Zerg!
"Hiss!"
The people watching the battle gasped, and then the human side cheered.
"Invincible! Who is this, invincible!"
"Fuck!, a martial arts master! He must be a martial arts master!"
"Ah! Brother is great, please give me your name, please post photos, please date!"
"Bugs are only worthy of looking up at the soles of shoes, handsome! So handsome!"
"Where are those bugs who just shouted, come on, keep shouting!"
The entire chat room was directly flooded with human messages, either worshipping Luo Yu or mocking the Zerg.
Luo Yu gave hope to many people. Humans can be so strong!
[You defeated your opponent. To facilitate entering the virtual arena next time, you can leave a code name]
"Code name?"
"Then just one word: Yu."
Immediately, Luo Yu's name in the arena changed from Earth human XX to Yu.
"Yu! It's the name of the Chinese!"
"Brother Yu, you are the hero in my heart."
"Brother Yu, which area are you from?"
"Okay, very good, Yu, right? We Zerg will go to call people now. Don't leave if you have the guts."
Regardless of the various comments in the chat room, Luo Yu directly collected the money and left.
After looking at the personal account, the amount of silver reached 6800. Originally, even if he won 2000, there was only 5300. The rest was the audience's entrance fee. It was a bloody profit.
"Let me see what good things I can buy."
He opened the mall and browsed it. After looking for a while, he suddenly found that there was a small tip that had been ignored before, because the mall had been crit once before, and it could not be crit again in the mall before the end of the month!
The mall will have a limit on the number of critical hits, and Luo Yu is still thinking about unlimited nesting dolls!
"Huh? Wait a minute, this reminder..."
Luo Yu accidentally opened the map, but found a row of small red words in the upper right corner of the map: There are 28 days left before the end of the month attack.
He hurriedly clicked in to see, but his forehead was sweating.
Before the end of each month, there will be a hardcore attack event. The intensity of the attack will be stronger than ordinary random events, which is the biggest threat to the trialers!
Luo Yu sent a regional chat as soon as possible.
Luo Yu: "Look at the map, is there a reminder of the end of the month attack?"
Fang Yumeng: "Really, fainted, what can I do, my sisters and I just built a wooden house..."
Alice: "Everyone must work hard to survive!"
The regional chat exploded, and everyone had a sense of urgency.
While talking to everyone, Luo Yu thought quickly in his heart, the construction of the wall must be accelerated, and the defense facilities of the base must also be put on the agenda!
When he opened the research interface, the densely packed technologies were not unlocked. He carefully looked at the defense technology tree. In the early stage, there were traps, shooting towers, watchtowers, etc., but Luo Yu's eyes were on one of the columns.
[Automatic crossbow: can be installed in places such as walls and shooting towers, automatically load crossbows and aim at enemies]
Automatic!
This is undoubtedly the best choice for Luo Yu, who has only one person in the base, but the problem is that if you want to unlock the automatic defense technology tree, there is a pre-research option: [Base automatic defense core]
The research funds of 5000 silver may be acceptable, but the materials for construction also need to be prepared by yourself.
3000 silver, 200 jade, 200 gold, and a beast soul core are also required. The price is very outrageous!
Of course, the automatic defense core device is extremely difficult to damage and can be carried with you, once and for all.
Originally, Luo Yu was thinking of making a small ranch to increase the success rate of animal taming, or making some soil cultivation to accelerate the growth of plants. Now it seems that automatic defense technology is the top priority!
Only by surviving can we have the capital to grow and develop.
Luo Yu engraved this sentence on the wooden table, and also engraved the next development plan on it to remind himself at all times.
Goal: Build a solid wall and unlock automatic technology before the end of the month to create automatic crossbows!
Without much hesitation, Luo Yu directly spent 5,000 silver to unlock the automatic defense core technology. There were still 1,800 silver left, so he kept it for now.
Looking at the time, there were still three hours before dark. Luo Yu carried the Tiangong knife and the pickaxe on his back and went to the mine.
The harder the stone bricks for building the wall, the better. Ordinary stones on the grassland can no longer meet Luo Yu's needs. The mine can produce hard stone raw materials such as black spot stone, and there is also a certain probability of digging out rare ores such as jade, gold, and silver.
Now of course, it's time to go mining!
As for the originally cut stones, you can make something else. Stone bricks are very useful.
The location of the mine is close to the purple mountains, but it is still relatively safe.
Walking into the cave, there are oil lamps sunk into the rocks on both sides of the rock wall. These are all there from the beginning, and cannot be moved and do not require adding burning materials.
After a while, we reached the end of the mine, and in front of us was a rock wall emitting a faint blue light. Without saying a word, Luo Yu took a pickaxe and started digging.
Nothing.
[Mining failed, your mining experience increased]
Because the mining level is only LV0, failure is normal.
Another pickaxe went down, this time a black spotty irregular stone rolled down from the glowing rock wall, which was the black spot stone.
The explosion rate of this kind of stone is relatively high, but the explosion rate of rare ores is ridiculously low.
"Bang!"
"Bang!"
Under continuous mining, hard stones such as black spot stone and granite kept rolling out. Because Luo Yu's basic attributes are high, even if the mining level is insufficient, the efficiency is still very considerable.
After a while, a small hill was piled up around him.
[Mining level increased to LV1]
"Finally upgraded."
Luo Yu exhaled, moved his shoulders and planned to take a rest. He looked at the pile of stones in front of him and found that carrying was also a problem.
At this time, he thought that he was not alone, but also had a dog.
No, a wolf!
After blowing a whistle, the blue wolf Ah Dai, who was patrolling the fields, ran over quickly, rushed into the mine in a moment, and rubbed Luo Yu's pants affectionately.
"Ah Dai, go and fetch 20 pieces of wood."
"Woo woo."
The blue wolf went immediately, and his efficiency was still very high. He quickly moved 20 units of wood over.
