The battle is far from over.
Energy Infusion!
Su Bai channeled the energy from the Holy Grail into the Holy Arrow, preparing to face the second wave of monsters.
Soon, the scorching area caused by the first strike of the solar flare disappeared.
One after another, lizard monsters crawled out.
More saber-toothed tiger monsters appeared in the portal on the right.
Buzz!!
The third portal directly in front of us began to rotate.
Another sneak attack.
However, Su Bai had anticipated this and was mentally prepared.
He controlled the Frost Dragon Tower and no longer paid attention to the boss monster.
Turn forward.
Intercept a group of attacking monsters that rushed out of the front portal.
On the right side, continue to use the combination of Fallen Dream and Holy Arrow to clear out the saber-toothed tiger monsters.
The Holy Arrow itself gains 1 energy with each attack.
It accumulates energy very quickly.
It reached 3 points per second.
It takes seven seconds to unleash a piercing arrow that deals basic damage, and only 17 seconds to unleash a piercing holy arrow that deals double damage.
It's easy to hold off waves on the right side without any special monsters using it.
And on the left side.
There were no more obstacles.
The lizard leader suddenly increased its speed.
In less than three seconds, it darted more than ten meters away, getting very close to the base crystal.
But at this moment.
The electromagnetic field it initially released eventually became ineffective.
Buzz!
The golden-red sundial emitted an incredibly intense light.
In the sky.
It was like a sun falling...
Boom!!!
The flames roared, the earth shook, and the intense heat from the impact created a wave of flames several meters high that spread outwards for more than ten meters.
After a period of intense burning.
All things return to stillness.
The enormous Thunder Lizard leader had been reduced to a charred shell.
As the wind blows.
It scattered into ashes with a crash.
Whoosh!
All the defensive towers present, except for the Holy Arrow, were upgraded by one level.
The Frost Wyrmling leveled up two more times.
Its size has grown larger and larger, and with its curled tail, its body is now over three meters long, already resembling a giant dragon.
The leader monster died.
The remaining monsters are just easy experience points.
[Battle over!]
[The level of all existing defensive towers will be automatically upgraded!]
[You have 3 choices!]
[Completion rewards have been accumulated; the current total rewards are: 2 gold and 70 silver coins!]
[Next wave of monsters countdown: 2m59 seconds!]
[Hint: You have defeated the first powerful boss in Challenge Mode and have received an extra reward!]
[Received: Challenge Item Pack!]
...
Sufficient rest time was still given after the fifth wave ended.
This indicates that the difficulty will increase in the next wave.
But Su Bai wasn't nervous.
Having successfully defended against the leader wave, the ordinary monster waves no longer pose much of a threat to him.
The next challenge that might get him stuck is anticipated.
It should be in the eighth wave.
According to the pattern.
The eighth wave will most likely also be an elite wave.
He looked around the room.
All the defensive towers have been significantly upgraded after the last wave ended:
Solar flare - Level 12.
Divine Warrior Totem - Level 11.
The Dream of Depravity - Level 11.
Holy Arrow - Level 10.
Eroding Winds - Level 10.
Refracting prism - Grade 10.
Frost Wyvern - Level 7.
Infuse the Holy Grail - Level 7.
Before he knew it, he had built eight defensive towers, and the entire defensive system was becoming more and more mature.
There are also many combinations between each defensive tower.
The combination of Solar Flare and Divine Totem is currently his strongest damage output combination.
In particular, with the infusion of the Holy Grail and the Energy Crystal, the output frequency of solar flares increased significantly.
A single defensive maneuver can unleash more than ten skills.
Explosive damage.
And once the Frost Wyrms caught up in level, their damage output also increased significantly.
A level 7 Frost Wyrm already has 560 points on its stat sheet, and its damage output against a single tower is already quite impressive.
Its only drawback is that it only has single-unit output capability.
But this will soon be remedied.
In comparison.
Holy Arrow also performed very well in the last wave.
After all, it has the support of three excellent defensive towers: the Refraction Prism, the Dream of Fallen Souls, and the Holy Grail.
They held the line.
but.
It has ultimately reached its limit.
If the waves are higher, and the monster's health increases, its damage output will be greatly reduced.
"A regular tower is still a regular tower after all..."
Su Bai sighed.
Unfortunately, his talents couldn't be utilized in this scenario; otherwise, he wouldn't have needed to consider this issue.
I calmed myself down slightly.
Su Bai examined the special reward he had just received.
This is a treasure chest.
Enable directly.
Ding!
A golden-white scroll appeared before his eyes as the light shone through.
[Infinite Possibilities]
【Props】

[Note: This item can only be used in the current challenge mode. After it takes effect, the probability of the growth-type main tower spawning in the next wave will increase slightly.]
This item can be saved for the next challenge.

...
"Um?"
"There's actually something like that..."
