889 Chapter 517: Six Million Rare Resources, A Wave of Harvest From Ell Kingdom [2/3]

Broken Mountain was a powerful single-target attack skill.

This skill could deal with troops with lower potential and levels than itself. If one looked up, it could generously fix the insufficient damage to the enemy’s top-tier units.

It would instantly explode with a vast destructive power if one used it to gang up on the boss. One could break through its defense.

The upper limit of Richard’s battle power soared once again.

He would need 500 units of gems to promote each stone statue of the dead. That was the only thing that made him helpless.

This round trip would consume 500,000 to 600,000 units.

Richard could only shake his head and sigh. Any aspect of the development of the territory required a massive amount of resources.

However, this is worth the resources.

He opened the technology panel of Twilight City and glanced after he regained composure.

[Axe of the Dead: Ordinary-Level Attack Technology]

[Bandaged Mummy: Elite-Level Attack Technology]

[Stone Statue of the Dead: Advanced-Level Attack Technology]

[Scorpion Warrior: Special-Level Attack Technology]

Richard sighed inwardly.

He had only developed the technology of four troops in half a year’s time. Moreover, the Bandaged Mummy and the Axe of the Dead Lairs were futile for various reasons.

He could only use the technology of the Stone Statue of the Dead and the Scorpion Warrior Lairs.

That was too slow.

Richard was a little troubled.

It took time for things like technology to settle down.

However, the current situation made him tense up. He had to do everything he could to speed up the improvement in this aspect.

Time wouldn’t wait for anyone. The enemies of Twilight City wouldn’t give him generous time.

Richard pondered. He was about to call Sam and the other Research & Development Department staff from the blacksmith shop to give them the next mission when the system notification sounded again.

[Ding~ The number of heroes in the blacksmith shop has exceeded 20. They have successfully developed a particular technology. The blacksmith shop can now start the team research and development mode.]

[Team Research and Development Mode: It requires at least ten relevant professional heroes to activate. Research and development speed increases by 20%, and the success rate increases by 20% after activation. Research and development speed and research and development success rate increase by 2%, with an upper limit of 50% for every additional recruit.]

[Note 1: A hero’s single characteristic cannot save team research and development. One should pay the whole amount.]

[Note 2: Increasing the investment of resources will increase the research speed.]

The notifications pleasantly surprised Richard after he repeatedly read.

He didn’t expect the number of people in scientific research could activate such a practical characteristic.

That was a bit mess.

For scientific research, the characteristic of the T-shirt was simply priceless.

Richard opened the troop attribute panel and glanced as he pondered.

He foremost needed to study the Radiant Moon 3-stars king mummies and combined troop–the sandstorm controllers.

The attack technology of these two powerful troops was still blank.

The sandstorm controllers needed a mage tower to research technology as a spellcaster troop. The blacksmith shop’s lack of skill could delay the work.

However, a Radiant Moon 3-stars, level 17 newborn king mummy of the Imperial Troop Lair was his pillar of support.

The strategic value of this mighty troop type soared after the Black Gold System could directly synthesize the King of the Imperial Troop Lair.

Offensive technology was undoubtedly the fastest and least costly way to increase the battle strength of the troops when they lacked resources and the potential to advance.

Richard pondered and reviewed the technology of the Stone Statue of the Dead Lair and tried to put it in the blacksmith shop for research.

However, the notifications shattered his thoughts.

[Ding~ The current level of the Twilight City is level 3 medium city–special-level. Please, upgrade to the big city before researching this technology.]

[Above the special-level was the glorious-level. The system couldn’t develop level 3 medium cities.]

Richard shook his head and looked at the scorpion warrior’s glorious-level technology with some emotion.

This technology was an exception for various reasons.

It could develop if the King of the Imperial Troop Lair used this technology.

Richard returned to his senses. He ordered the guards to call Adele and Sam to bring them to the Lord’s Mansion.

The sound of footsteps came from outside not long after the soldiers left.

Adele was dirty and had a panda eye. Sam had only a single arm and stepped into the house.

They bowed immediately at the sight of Richard.

“Good day, Lord Richard…”

Richard looked at Adele. She was embarrassed about her appearance when she entered the mansion.

This blacksmith girl was generously pretty, but smoke, dust, oil, grease, and fire defiled her natural charm.

He looked at the excited one-armed blacksmith, Sam.

“Sam, have you made any new progress in your research on the stone statues of the dead?”

Sam said excitedly, “That’s right, my Lord!”

“Thanks to the dungeon blacksmiths that Lady Adele brought from the underground world. We are now carrying out an additional reinforcement on the bodies of the stone statues of the dead. The steps included the smelting with rare resources, and then…”

Sam spoke for seven to eight minutes before he finally stopped.

Richard couldn’t help but smile. These scientific researchers seemed to be on steroids when one asked to discuss their field. They talked remarkably excited about them.

Richard praised the blacksmiths afterward. He said slowly, “Group research is undoubtedly an effective method. It can enormously speed up the research progress…”

“Adele, proceed to Bloodhoof City to find blacksmiths for us. Bring also the lower levels. We can first research the primary attack technology of the troop.”

Twilight City earned incomparable resources, although the cost of various aspects increased.

It can support the scientific research expenses of several troops at the same time.

That instantly perked Adele up.
