Chu You looked at the four words for a while, and just looked at it like that, as if he was facing a major choice!

Then my heart moved, and I chose the high-level scientific research of the fortress!

You can see that there are four high-level research options, which are: Battle, Punishment, Building, and Alliance!

Each option is a mysterious, esoteric magic array card, and there are four of these cards in total, corresponding to the four high-level scientific research options!

And at the bottom of these four mysterious and mysterious magic array cards, this is a gray galaxy nebula pattern, and below the pattern is a set of gray text, which reads: Activate the spirit of the fortress!

These words can't be activated because they're gray, so what is the premise for activating it?

The answer, of course, is to complete all the advanced scientific research in order to be eligible to launch this ultimate option!

His eyes looked at the four high-level options, and Chu You chose to fight first.

Then the magic card corresponding to the battle is opened, and the last set of skill trees appears in the interface.

All the skills in this skill tree are high-level combat research projects!

Each research project needs to be upgraded to level 10, and if any of these skills are not upgraded to level 10, not only will they not be able to trigger the ability to activate the next skill tree, but they will also not be able to activate the Spirit of the Stronghold.

Therefore, Chu You can only upgrade from the first scientific research project, and the first combat scientific research project is: 0/10 of the army's total attributes!

All Army Attributes Level 1: Increases all Army Attributes of all Ruling Guild player members by 20%!

Research resources: 20,000 wood, 20,000 ore, 10,000 mercury, 5,000 sulfur, 5,000 gems, 500,000 gold coins.

Study time: 90 days!

With his head slightly tilted, Chu You still stared at the relevant details of the scientific research project in front of him, and it could be seen from the research resources that the research of high-level scientific research not only requires strategic resources, but also gold coins, in fact, gold coins themselves are also a kind of strategic resources.

In the past, ordinary scientific research didn't need gold coins, only strategic resources were needed, but high-level scientific research increased gold resources, and the cost of gold coins was huge, 500,000 were needed for level 1, so what about level 2? This is also the first combat scientific research project in the first combat scientific research system!

The next moment, I chose to study!

In an instant, some of his strategic resources and gold coins were deducted accordingly.

I saw that the light of the huge scientific core crystal increased a little, and at the same time, the scientific research project showed its completion time: 90 days!

This means that it will take 90 days for the research project to be completed, and the content of the research project will be applied to all members of the ruling guild.

After that, I opened the interface and looked at the few remaining scientific research time acceleration cards, which were originally purchased from an ancient god NPC on Fortune Island.

Taking a deep breath, and then using a total of 90 days of scientific research time acceleration cards, this scientific research project was completed by Chu You in a very short time.

When the research was completed, I saw that Chu You's body lit up with a golden light, and it quickly disappeared.

System: You have researched and completed the level 1 scientific research project of all the attributes of the army, and its scientific research effect will be applied to all members of your guild!

At the same moment, Zhao Feifei also saw a golden light on his body......

Not only that, but Tantai Jingning, who was somewhere, stopped her posture, because her body lit up with a golden light....

This effect also appeared Miao Jiu'er, and the people around her looked at the effect that appeared on her.

The three daughters of this Immortal Guild have all received a prompt from the system!

System: Guildmaster 'Night' has completed the Battle Level 1 Research Project in the Advanced Research Project of the Ruling Fortress: Level 1 of all attributes of the army! This scientific research will work on you!

After upgrading this scientific research project, you can see that the skills in the scientific research skill tree below are lit up, which is activated, but it can only be upgraded by 1 level, because the entire attribute skills of the army above have only been upgraded by 1 level.

And the name of this high-level combat research project that has just been activated is: Fortress Skill: Space Enhancement 0/10!

Fortress Skill Space Enhancement Level 1: The maximum teleportation distance is 50 meters, the movement speed increases by 20% after teleportation, lasts for 3 seconds, the skill has a cooldown of 3 minutes, no need to consume mana value, no level limit, shared by all professions, and the target is members of the Ruling Guild!

Research Resources: 20,000 Timber, 20,000 Ore, 8,000 Crystals, 8,000 Brimstone, 1,000,000 Gold!

Duration of study: 100 days!

Without hesitation, Chu You activated this scientific research combat skill program, and immediately deducted some of his own resources accordingly.

Then, a total of 100 days of time acceleration cards were used on the scientific research time accelerator card, and finally this high-level scientific research level 1 project was studied!

Immediately, just like before, all the people in the Immortal Guild online lit up, and there was also a system prompt.

And at this moment, the three daughters of the Immortal Guild were shocked!

Because, they actually saw that a new skill had been added to their skill tree: Fortress Skill Space Enhancement Level 1!

Unbelievable!!

Zhao Feifei suddenly raised his eyes and looked at the back of the man standing not far away, under the huge core crystal!

This man, what is he doing? It can actually make the members of the entire guild have free skills, and they are also spatial skills!

Spatial skills, that's the trump card skill of all skills, and it's extremely awesome.

And now, the members of the entire guild actually have this skill, and judging from the hint of 'level 1', there is still room for a significant increase in the advanced skill of this unexpected joy!

At this moment, different degrees of chilling due to different feelings emerged in the three daughters of the Immortal Guild!

Zhao Feifei can be said to feel the deepest, because the Immortal Guild currently has only 5 people, and the number of people in the Immortal Guild is 50,000!

If the Immortal Guild can really recruit 50,000 people, then all 50,000 people have this skill!

Isn't it scary?!

Immediately, a voice sounded in Chu You's friend bar, but he didn't open it, and his eyes were still looking at high-level scientific research.

Because the above research is only upgraded to level 1, the spatial skill enhancement research can only be upgraded by level 1, and there is no trigger to activate the next high-level scientific skill.

There is no more research acceleration card!

Chu You couldn't help but feel a little deflated in his heart.

System: Warning! The location of your guild exchange in Nanshan City has changed, you can find it!

Ignoring the prompts of the system, Chu You chose to start the level 2 scientific research project to upgrade all the attributes of the army, and the gold coins of this project will cost 1 million.

All Army Attributes Level 2: Increases all Army Attributes of its ruling guild player members by 35%!

In the end, Chu You upgraded the scientific research of all the attributes of the army to level 10 in one go!

The price paid is that all the scientific research accelerator cards are consumed, and the strategic resources consumed are even greater, and the gold coins are consumed in total, 46 million!

From the time he came here until now, the total amount of gold consumed is 47.5 million!

The body has changed from 250 million to more than 200 million gold coins.

That's the price of researching advanced research, because it works just like a guild skill tree, and it's total!

The accelerator card is exhausted, and the strategic resources are almost exhausted!

Hehe....

Army Stats Level 10: Increases all armies of its ruling guild player members by 200%!
