The Invincible Overlord of Heroes.

Talent: [Fearless Knight], Tahan gains extra courage and ability when commanding a knight unit.

When leading knight-type troops such as Apprentice Knights, Knight Squires, Knights, Grand Knights, and Gallant Knights, the morale is increased by an additional +5.

All knights' attack and defense attributes increase by an additional 20%, and their movement speed and attack speed increase by an additional 20%.

When charging, all knights' speed and final damage are increased by an additional 5%.

Additional Talent: [Lightning Knight], Tahan is immune to all air spell damage, automatically gains all air spells, and gains an additional 20% damage when casting air spells.

The knights under your command have 20% more resistance to air spells, are immune to the paralysis effect of lightning spells, and their attack speed and movement speed increase by an additional 10%.

Both of Tahan's talents have extremely powerful effects.

Originally, Count Aini was unique among earls because of his talent in cavalry, otherwise he would not have been able to control the vast grassland.

However, Tahan's fearless knights are obviously more powerful than Aini's cavalry talents, and much more powerful.

Tahan has all the abilities that Aini has, and also increases the morale of the troops, charge speed, and final damage.

The additional talent Lightning Knight further enhances the knight's movement speed and attack speed.

The movement speed and attack speed alone are already very powerful among the second talents.

It also increases the knight's damage to air spells and makes him immune to paralysis effects.

In addition, Tahan is completely immune to air spells and can cast all air spells.

As a knight, Tahan's intelligence and mental attributes are not high.

These two attributes are not high. One is that they cannot release spells that require high mana, or cannot afford to cast spells multiple times.

The other is that the spell power is relatively low and the duration is relatively short.

Even for high-level spells, the difference between a spellcaster with high spirit and one with low spirit is terrifying.

But Tahan has another advantage, that is, he does not need to learn wisdom magic, and he can also obtain level 3-5, or even forbidden level air spells.

That’s right, even Xu Lai didn’t know where to learn the forbidden spell, but Tahan knew it, and he learned it automatically without even using the wisdom magic.

[Lightning Storm]: Forbidden spell, consumes 2500 mana points and is released to the designated area on the battlefield.

In the designated area, the lightning storm will release lightning at a rate of Spirit +1 per second for 4 hours.

Each lightning bolt will cause a fixed amount of damage of 150+ spirit points, and paralyze the person hit by the lightning for 1-3 seconds.

Ultimate Air Magic Effect: Mana consumption reduced by 75%, fixed damage increased by 75%, basic number of lightning increased by 5, and spirit coefficient increased by 75%.

即消耗625点法力值，每秒释放精神*1.75+6条闪电，每条闪电造成262点+精神*1.75的伤害并麻痹1.75-5.25秒。

Note: This spell has a minimum and maximum specified range, the minimum is the land within a circle with a radius of 1000 meters, and the maximum is a circle with a radius of spirit*1000 meters.

Note 2: The displayed effect of this spell does not take into account the additional special effects of the ultimate air spell and the talent effect of the Lightning Knight.

Note 3: After this spell is cast, the caster will not be able to cast any air spells (including using spell scrolls) for the next month.

Note 4: Forbidden spells transcend all spell levels. Ordinary anti-magic skin cannot resist forbidden spells (including black dragons).

However, magic immunity and air spell immunity can ignore the influence of this spell, and effects such as reducing spell damage will continue to be effective.

At the same time, specializations or talents such as resistance also have a chance to directly resist lightning damage and paralysis effects.

Tahan's basic intelligence is 15 points and his spirit is 14 points. This transformation did not change his intelligence and spirit attributes.

However, because he obtained the ultimate air magic and was affected by the special effects of the intermediate air magic, his spirit increased by 2 points.

Even with these two points, Tahan's spirit value is only 2, but this is his state after wearing white equipment.

After becoming a hero, first of all, Tahan can access all the attribute points that Xu Lai had recorded before.

Of course, we can’t go to places that are too far away. We can only visit the Observatory and the Star Axis, or at most go to the Northern Empire and visit the Library of Wise Men.

The dragon power potion is not easy to make, but Xu Lai has a full set of black dragon and red dragon, so it should be no problem to ask someone to make it.

Ordinary intelligence and mental potions can basically be bought with money, but crystals depend on whether the temple has any in stock.

With this calculation, Tahan can at least increase his intelligence and spirit by 7 points.

If you are lucky, with the addition of the upgradeable Ancient Tree of Wisdom, your intelligence and spirit may be able to increase by about 10 points.

After all, Tahan is a physical professional. If he wants to release forbidden spells, he will need at least a magic amulet with high mana.

Therefore, Xu Lai could not equip him with too many magic equipment. It was estimated that the equipment could only increase his spirit by about 10 points at most.

In this way, Tahan's spirit value can at least rise to around 35 points, which is already a high value.

In terms of specialization, if you learn other types of magic, or learn the art of wisdom, your intelligence and spirit can still continue to increase.

But based on Xu Lai's understanding of Tahan, this guy probably has no interest in magic.

Moreover, he has already learned all the air spells including forbidden spells without using the wisdom spell, so he probably won't learn the wisdom spell again.

If calculated based on 35 points of spirit, 67.25 lightning bolts can be released per second within the coverage area of ​​the lightning storm, and each lightning bolt can cause 324 points of damage.

In terms of damage and quantity, it still has not reached the standard of forbidden spells in Xu Lai's mind.

Even with the special effects of the ultimate air spell and the talent of Tahan Lightning Knight, the power of air spells is enhanced by 50% in total.

But it can only happen 100 times per second, and only causes more than 480 points of damage each time.

With over 480 points of damage, even without considering physical resistance, it is difficult to kill large creatures with "Giant" in it, as the target has no resistance either.

More than 100 times per second may seem like a lot, but for a large army, it is completely sustainable.

The key point is that this forbidden spell can last for 4 hours, which is a full 14400 seconds.

If there is only one target within the range of this forbidden spell, then this unlucky guy will have to endure up to 7 million damages.

Of course, this forbidden spell does not distinguish between friend and foe, and the radius must be at least 1000 meters.

In such a vast area, even if it is an uninhabited area, there cannot be a lack of life.

It is really unlikely to expect all lightning to hit one person.

However, if he really wants to take full damage, Tahan can equip himself with some artifacts that can increase the damage of air spells, or treasures such as the Air Spirit Ball.

In that case, it would really be a nightmare for the enemy's large army.

Unfortunately, the Lightning Storm cannot move and needs to be in a fixed position. It can only cause satisfactory damage when used in more specific situations.

Of course, this also has its advantages. At least when casting spells, you can avoid the position of your own army.

Xu Lai was eager to see the power of the forbidden spell, and there happened to be a suitable target in front of him.

Xu Lai did not think that he made a mistake in deciding to besiege Kasai City, but this decision did cause great harm to the residents of Kasai City.

The city of Kasai had been under siege for nearly 20 days, and the demons in the city had long been out of food. Even the little demons and low-level demons like the jumping demons had been eaten up. Even the low-level demons in his own family had been eaten up. No matter how big Ferris's face was, he couldn't stop the demons from eating people.

Even if Xu Lai did not attack the city, as long as he did not surround the city, Ferris would find a way to transfer supplies from the rear.

But Xu Lai is still there, and his cavalry still controls the entire grassland. Even if Ferris has the ability, he may not do so.

Although she had never heard of besieging a point and attacking its reinforcements, she and her main demon force were trapped by Xu Lai. Could the demons that came to deliver supplies be able to defeat Xu Lai?

With this concern, even if Xu Lai did not besiege the city, the remaining residents in the city could not be saved.

Unless Xu Lai gives up Kasai City, or even the entire Great Plains, the devil will be at ease.

Or maybe he would not give the devil any chance to breathe and would launch a desperate attack on the city.

But both of these points are not very realistic. Xu Lai would neither abandon the Great Plains nor attack the city desperately regardless of casualties.

The remaining residents in Kasai City are lives, so aren’t the soldiers he brought from the grassland also lives?
In fact, if there was no such opportunity, Xu Lai would still be willing to continue waiting.

The air superiority is still on their side. Elvy and Eric take turns conducting reconnaissance at high altitudes every day.

The demons at this point were not at their wit's end, but if Xu Lai besieged the city for another week, at least half of them would die.

Even so, more than 100,000 little demons and jumping demons have died, nearly one-fifth of all demons.

Now the demons in the city have eaten everything, and the remaining low-level demons can only eat for two or three days at most.

After two or three days, the demons would either break out or starve.

Once the demons break through, they will naturally have to give up their own city defense advantages.

No matter how skilled Ferris is at operating the crossbow, the crossbow is not an archer. Not only does it move slowly, it also requires at least two people to operate it.

Moreover, without the city walls and arrow towers, even if Ferris still had enough crossbows, Xu Lai would not be outmatched in a shootout.

If they launch a siege by force, there will be so many crossbows and a million-level demon army.

Even if Xu Lai could capture the city of Kasai, he would inevitably suffer heavy casualties.

Angels do not have such a large number of resurrections, and Xu Lai does not have any extra summoned troops to sacrifice.

This will also mean that most of the soldiers who died in battle will have died in vain.

This was something Xu Lai didn't want to see at all. Compared to this, he would rather let Dur and Rio Canal wait a few more days.

But now that Tahan has awakened, things are different. He happened to have learned the forbidden spell, and his level is relatively low.

Xu Lai simply handed over the entire Kasai City to Tahan and tried out the power of the forbidden spell.

Once this is released, you won't be able to cast spells or even use magic scrolls for the next month.

Just for this occasion, Xu Lai got all the best equipment he could find.

Not only did he lend out his Angel Alliance suit, the Hand of Vulcan, he also found a magic potion that could enhance air spells by 20%.

The only pity is that Xu Lai doesn’t have a Qi Ling Ball.

If he had known this would happen earlier, when he opened the treasure chest, Xu Lai would definitely keep the Qi Ling Ball instead of choosing the War Horn.

The war horn is still treasured in Xu Lai's space backpack.

As an important prop for a comeback, it's a good thing that this thing doesn't appear.

But when it comes to snowballing, high-level equipment like the Qi Ling Ball is naturally more cost-effective.

The demons cleared out all the humans in the city, which indirectly helped Xu Lai make up his mind.

Otherwise, Xu Lai really wouldn't have the heart to use a spell like Lightning Storm, which doesn't distinguish between friend and foe, on his own people.

By wearing the Angel Alliance and using high-level spell equipment such as magic amulets, Tahan's spirit value broke through 40 points.

But in Tahan's own words, he was still not used to wearing powerful equipment, and he had never learned how to cast spells.

Xu Lai told the other party that it was very simple. The only thing he had to do was to rely on his spirit to control the coverage of the spell.

Before he could cast the spell, he still needed to withstand the demon's crossbow fire and rush back within one minute of invincibility.

In order to avoid any accidents, Xu Lai also specially recruited a group of heavy shield infantry to protect some newly promoted bishops.

Once Tahan's health drops, these priests will immediately replenish his health.

With the Angel Alliance suit on, and having learned the ultimate defense technique himself, even if the holy armor disappears and he is hit by a volley of crossbows, he should not be killed instantly.

As long as he is not killed instantly, the priests prepared by Xu Lai can immediately increase Tahan's health.

But it turned out that all the preparations made by Xu Lai were completely unnecessary.

Wearing the holy armor, Tahan felt that his spirit could cover the entire city of Kasai after taking only a few steps.

After all, wearing a complete set of Angel Alliance, covering the city of Kasai is nothing.

The huge crossbow arrow was blocked by the invincible light of the holy armor, and Tahan began to chant a spell.

After becoming a hero, you can directly use the spell book to cast spells.

However, forbidden spells cannot be recorded in books, otherwise no one would have never seen them.

Fortunately, although he cannot use the spell book to cast spells, Tahan can use this spell instinctively.

As the light of the holy armor disappeared, crossbow arrows shot directly at the Lion King's shield and the magical armor.

After merging into the Angel Alliance, their defense is no longer the same as before, and even crossbows as powerful as spears cannot penetrate them.

With the replenishment of holy light, Tahan's health points were always maintained at full value, with almost no change.

Ferris and Mendis on the city wall were all staring at Tahan, not understanding what he was doing.

Logically speaking, even if he rushed up to cast the spell, five minutes had passed and the spell would have fallen.

"Is this guy here to trick us into using our crossbow arrows?"

The city of Kasai has been under siege until now, and has to fight against Xu Lai's catapult troops every day. Many houses in the city have been demolished, and there are indeed not many crossbows in stock.

Mendis also frowned. His intuition told him that this matter was not simple, but he couldn't see it at all.

Xu Lai was even more ashamed. Fortunately, he had prepared a team of priests in advance and also conducted a test in advance.

Who could have known that spells that used to be cast with just a flick of the finger would suddenly become so far away when it came to forbidden spells?

The scary thing is not that the end is far away, but that everyone is watching. Three minutes after Tahan cast the spell, a faint aura of terror emerged from him.

By the sixth minute, the sky and the earth had begun to gradually change color, with Tahan at the center.

By the ninth minute, even a fool could tell that Tahan was doing something horrible. The dark clouds, as black as ink, solidified firmly over the city of Kasai. (End of this chapter)
