Naruto: The dog card gave me strength at the beginning

Thanks to this period of time, Chiyo has been organizing the Sand Village to attack Konoha.

These exchange points are the contributions of the Sand Village during this period.

Aizen Shinnosuke looked at these exchange points and calculated what he had not yet obtained.

So far, Aizen Shinnosuke has unlocked the following cards: Kill, Flash, Thunder Kill, Fire Kill, Take Advantage of the Opportunity, Demolish the Bridge after Crossing the River, Peach, Happy and Forgetful, Invulnerable, Out of Nothing, Southern Barbarian Invasion, Ten Thousand Arrows, Cut off the Food and Bread, Eight Diagrams Formation, Ancient Ingot Blade, Niwang Shield, Lightning, Absolute Shadow, Duel, Fire Attack, Wine, Iron Chain, Male and Female Double-edged Sword, Dilu, Dayuan, Qingguang Sword, Borrow a Knife to Kill, A Good Harvest, Peach Garden Oath, Silver Lion, Rattan Armor, Ice Sword, Zhangba Snake Spear.

What he has not obtained is left with: Kirin Bow, Qinglong Yanyue Blade, Guanshi Axe, Zhuge Liannu, etc.

Anyway, what is left in the end are weapons and horses. These things do not add much to Aizen Shinnosuke's benefit and can be considered dispensable.

"System, what you said before, that you can reduce the cooldown, how do you do it?"

That's right, Aizen Shinnosuke is not going to unlock the remaining cards now. He is now thinking about reducing the cooldown of the cards, otherwise, when the battle comes, if all his cards are on cooldown, then he will be stunned.

【The host can click on the card to view its effects and upgrade it!】

"Upgrade?"

Aizen Shinnosuke agreed. If he put it that way, it made sense.

Shortening the waiting time after consuming a card, isn't this an upgrade?

While thinking, Aizen Shinnosuke clicked on the cards he had obtained according to the system unlocking:

Stealing, Demolishing Bridges, Invulnerable, Barbarian Invasion, Thousands of Arrows, Chained Chains, Creating Something Out of Nothing, Killing with a Borrowed Knife, Forgetting to Return to Homeland, Duel, Good Harvest, Peach Garden Oath, and Cut off from Food and Bread.

The above are all the cards he has in his hand so far, which have cooling time. Those with low cooling time, such as Duel and Invulnerable, only need three to five minutes of cooling time. And those with long cooling time, such as Effect 2's Creating Something Out of Nothing and Killing with a Borrowed Knife, the cooling time of these two cards is as high as 24 hours, a whole day. Aizen

Shinnosuke looked at it for a long time, and then tried to reach out and click on Duel.

【Do you want to upgrade the duel?】

"yes!"

【Consume 50 points......Hand: Duel! Upgrading......】

As Aizen Shinnosuke gave the order, the mechanical sound of the system suddenly sounded, and the next second, the duel card was suddenly wrapped in a golden light.

Under Aizen Shinnosuke's gaze, the duel card that was originally white in color turned into a golden card after the golden light flashed.

"This color, could it be......"General?""

Back then, before Aizen Shinnosuke crossed over, he was just a general with a flag. Now, he can use the general's golden hand card?

Aizen Shinnosuke took out the upgraded duel card with his backhand. Looking at the golden card in his hand, Aizen Shinnosuke was stunned.

This look......It is the golden card in Three Kingdoms Killing after upgrading to the general!

Shinnosuke Aizen looked at the golden card in his hand, and found that not only the appearance, but also the effect of the card after activation has changed to a certain extent. Shinnosuke Aizen searched for a long time, and finally caught a bug on the ground, and then Shinnosuke Aizen directly fought a duel with the bug on the ground. As a result, in the golden light, a powerful void axe shadow chopped down, and then the bug was chopped in half.

""What the hell? So awesome?"

Shinnosuke Aizen also saw the axe shadow just now. Even though it wasn't him who was hit, Shinnosuke Aizen was still scared.

"It's amazing! It's different after the upgrade!"

Aizen Shinnosuke sighed, and at the same time found that the duel cards, whether in the system or in reality, had also undergone some changes.

【Duel: Consume a certain amount of chakra and release it on a designated character, causing the opponent to suffer an unavoidable injury. The original cooldown has disappeared, which means that now Aizen Shinnosuke can perform the Duel without interruption.......Couldn't I just duel endlessly and duel the ninja on the other side to death? After all, the damage caused by a duel is unavoidable!

Moreover, the huge void axe shadow just now......Aizen Shinnosuke really couldn't imagine that there was anyone in this world who could dodge!

After upgrading the duel, Aizen Shinnosuke, who was in a good mood, turned around and clicked on the two cards of Crossing the River and Demolishing the Bridge and Stealing.

"The system has been upgraded to deal with stealing and bridge-breaking!"

【Consume 100 points to upgrade the stealing and bridge-breaking skills! Upgrading......】

Just like before, with Aizen Shinnosuke's order, the cards of Crossing the River to Demolish the Bridge and Stealing the Sheep immediately flashed with golden light, just like the previous duel.

【Stealing: Consume a certain amount of chakra to obtain a ninjutsu from the opponent. When using the opponent's ninjutsu, you don't have to consume chakra.

Demolishing a Bridge: Consume a certain amount of chakra to"remove" a ninjutsu from the opponent, making the opponent unable to use the demolished ninjutsu for a short period of time.

Similarly, Stealing and Demolishing a Bridge have no cooldown. Now, Shinnosuke Aizen dares to say directly: No matter what ninjutsu, it is useless in front of Shinnosuke Aizen!

In other words, he doesn't know that he can cast���Are there any other restrictions when performing the surgery?

If there are no restrictions ,......Can I try out Uchiha Fugaku's Mangekyō?

Especially in the late period of the Fourth Ninja World War in the anime, when he used Susanoo one after another like they were free.

And more importantly, there is Kaguya Otsutsuki, who is known as the goddess. Her ninjutsu are also very good. Shinnosuke Aizen drools just thinking about it!

After wiping his saliva, in the next period of time, Shinnosuke Aizen used up all the exchange points in his hand and upgraded his hand cards to a certain extent.

After the hand cards were upgraded, Shinnosuke Aizen also directly advanced from an elite jonin to a Kage-level powerhouse (self-proclaimed, the card is still an elite jonin)
