Spellcasting is a permanent addition and my skills are all forbidden spells.

Chapter 17 There was obviously an accident

 The production of black iron level BOSS is at the top level.

The three black iron bosses before and after all have black iron level equipment, so you are very lucky!

 Lu Cheng was very satisfied and looked at the origin of the spiritual ring.

He has used this kind of thing a lot in his previous life and is very familiar with it.

Hold it in your hand, the original properties of the spiritual ring are revealed.

 …

  【Origin of Spiritual Ring】

 【Quality: black iron grade. 】

 【Effect: Can be used on ring-type equipment, providing an increase, with a minimum 15% chance of improving its quality to black iron level. 】

 【Restrictions: Ring equipment, level no more than 10, quality no more than rare. 】

 …

 After reading the attributes, Lu Cheng nodded.

 Just like in his memory, this thing is a kind of equipment upgrade stone.

And it’s also a ring type, which is quite rare.

 Lu Cheng took off the secret magic ring.

 This rare ring was created by a level 3 mutated stone beetle.

 As he continues to level up, he is no longer good enough.

 The most important thing is storage space.

 Store food, drinking water, and various explosive equipment.

 One cubic meter is really not enough.

It was revealed earlier that the length of the long bow was more than one meter, and it took him a lot of effort to stuff it into the storage space.

“Arcane Ring of Amplification.”

Lu Cheng picked up the source of the spiritual ring and used it directly.

 A faint blue light lit up, wrapping around the secret magic ring, constantly changing.

 【Increasing, it takes twenty minutes...】

The system prompts.

 Lu Cheng couldn't help but look forward to it.

  He is still very optimistic about the chances of success of the increase.

 Although the effect column says the minimum chance is 15%.

 But the actual probability depends on the equipment itself.

 The stronger the equipment, the lower the chance of upgrading. If the level is the top ten and the quality is rare, then the lowest chance is 15%.

And the secret magic ring is only level three, and the guaranteed success rate is also in the 50s or 60s.

 Lu Cheng put away the secret magic ring, looked at the direction, and started on his way.

 There are still twenty minutes before the monster wave begins, and there is still the last level 8 BOSS left.

 The BOSS with the highest level will not escape from the monster wave and can only be confronted head-on.

 It will take about twenty or thirty minutes to rush back to the settlement from here, which is just enough to complete the increase.

 …

 …

Settlement No. 1024.

 “Everyone, prepare to fight as planned!”

Li Yuanqing stood at the forefront and gave orders.

 “Yes, defend the settlement!”

Beside him, nearly a thousand people from Li Technology shouted loudly.

 Suddenly, impassioned shouts came one after another.

 “Defend the settlement!”

 “Defend the settlement!”

 There were more than 18,000 people in the settlement at this time, and more than 90% of them stood on the front line and obeyed the orders.

 The settlement will be destroyed if we take a step back. At this critical moment, everyone is united as never before.

Looking at this scene, Li Yuanqing nodded slightly.

 Then, he looked at Xiao Muxue and asked in a low voice: "Mu Xue, how is the momentum going now?"

 In just a dozen hours, his view of Xiao Muxue changed a lot.

This rich lady of the family did not hide her secrets when sharing information, which was a great help to him.

 And now, he is on the front line personally.

Xiao Muxue's face was a little pale. She looked around and said, "No... everyone is still covered in black air, and... it's getting thicker!"

 “It shouldn’t be.”

Li Yuanqing frowned slightly.

 There are no elites among the monsters anymore. Are they still invincible?

“Everyone, stay in position, fight conservatively, and save your life first. In addition, personnel in the south will evacuate immediately.”

Li Yuanqing waved his hand.

He made many preparations and moved the wounded, old and weak to the south to facilitate their escape if the situation went wrong. Following his arrangement, many people moved quickly.

 The battlefield is located between two residential buildings, and the space is not large.

 Melee professions stay in the middle of residential buildings.

 Hong-distance people have boarded residential buildings one after another and stayed at the windows.

 【Monster wave attack countdown: 5 minutes...】

The tide of monsters is less than 500 meters away from the settlement. In the night, pairs of scarlet eyes are watching eagerly.

"Roar-"

The moment the countdown ended, the roar of beasts and the chirping of insects sounded like a mountain roar and a tsunami!

Thousands of monsters ran wildly, rushing in like a tidal wave, rolling up waves of smoke and dust!

 “Attack!”

Li Yuanqing roared.

 The monster group rushed into the crowd, and a melee broke out in an instant!

 “Don’t break up the formation, hold the pass, retreat the wounded, and put the backup on top!”

Li Yuanqing commanded, pulled out a magic wand, and worked hard to create a fireball.

 He is a magician and has some combat power.

“There is a chance! Both of these monsters are melee combatants and can cause limited damage to us!”

 Observing the situation, Li Yuanqing felt excited.

 But the next moment, a sudden change occurred!

 I saw that the ground suddenly rose up, and then suddenly broke open.

A giant robot with a height of two stories emerged from the ground. Its body was in tatters, but it was extremely powerful. With a swing of its robotic arm, it could sweep away dozens of people!

“Elite-level earth-drilling robot, HP...140,000??”

 Someone yelled, announcing the attributes of this robot.

 Almost at the same time, the southern part of the settlement suddenly came into crisis!

Just like this giant robot, there are also robots emerging from the ground in the south of the settlement, blocking the escape route!

Although they are much smaller in size, there are too many of them, thousands of them!

 Not only in the north and south, but also in the other two directions, monsters are also appearing!

Most of the human power is in the north. The power on these two sides is too weak and can be broken through in an instant!

"how so?"

Li Yuanqing's eyes darkened.

 All the information he received, as well as the survivors who escaped from the surrounding settlements, all said the same thing.

 The monster wave will only attack from one direction until the core of the settlement is destroyed.

 But now, the situation is not like this, monsters are coming from all directions!

 In an instant, the situation deteriorated to a desperate situation!

 …

 …

Lu Cheng hurried on his way, and when he was still a few minutes away from the settlement, the system prompt rang.

  【Ding, the increase is completed. 】

　　【The arcane ring's amplification was successful, and it was upgraded to a black iron level equipment: the arcane iron ring! 】

 …

  【Secret Iron Ring】

  【Ring Slot】

 【Quality: black iron grade. 】

 【Wearing requirements: Spell profession, level 7 or above, mental attribute 23 or above. 】

　　【Maximum mana +180, intelligence +18, spirit +12, mana recovery +2 per minute. 】

 【Special Effect 1: Actively used, it can instantly restore 150 mana points, and the cooling time is 10 minutes. 】

 【Special Effect 2: Provides 2mx2mx2m storage space. 】

 …

Lu Cheng's eyes lit up when he saw the properties of the secret iron ring.

 Level 3 rare equipment has been upgraded to level 7 black iron equipment, and the attribute bonus alone has been doubled.

 12 points of spirit, plus its own mana bonus, this is the upper limit of 300 mana points!

There are also two special effects, both of which have been greatly improved.

  The active effect of mana recovery has been increased from 30 points to 150 points, which is a huge increase.

 The storage space has increased even more, from 1x1x1 to 2x2x2, which is equivalent to eight times the original space.

"Not bad."

Lu Cheng equipped the ring and rushed to the settlement without delay.

 As we approached the settlement, we could hear shouts of killing in the distance, and the smell of blood filled the air.

"Um?"

Lu Cheng couldn't help but frown when he noticed the blood.

 With such a strong smell of blood, I’m afraid the battle in the settlement will be very fierce!

 However, the attack of the monster wave has clearly just begun!

Lu Cheng's heart sank.

He lured back the two black iron bosses in advance. If nothing else happens, defending the city won't be so difficult.

 But now, something obviously happened!

Lu Cheng ran wildly, and a few minutes later, the scene in the settlement came into view.
