"System, can't skills be upgraded?" Wu Fa couldn't help but ask.

"Ask the host to find the appropriate skill to replace or fuse."

Replacement?

Fusion?

"What's the fusion method?"

"After the host attribute reaches the standard, you can choose skills for fusion and upgrade by paying the source force."

"Testing."

"Fusion Ability ...... Detected"

"Concealment (F-), silent step (F). Fusion Front: Agile F+. Costs 20 Source Power to fuse. ”

"Aim (F-), Throw (F). Fusion front: Strength F+, Agility F. Costs 20 Source Power to fuse. ”

This fusion is a waste of points than directly learning skills, but now Wu Fa is not short of numbers, he still has 55 points in his hands, and there are still two remaining skills in fusing these two skills.

"Give it a try."

Wu Fa was very interested, "The system, the fusion of 'hidden' and 'silent steps'." ”

After deducting 20 points of source power, Wu Fa's skill panel suddenly changed, and the skills of 'Concealment' and 'Silent Step' disappeared, and were replaced by a skill called 'Extinction'.

"Extinct: F+. Front: Agile F+. ”

F+ level skills!

An F- and an F, actually fused to form F+!

F-level upper-level skills are sold for 500 points in the academy! He was able to do it with just 20 points of source power?

If anyone hears Wu Fa's heart, they will definitely beat him up.

Just 20 points?

Although the digitization of the source force is the patent of the system, when converted, it is not 'just' to let an extraordinary person go from the blank to the source force level of F-.

Qi Sisi killed an unknown number of mutant mad ghosts under the circumstance that Wu Fa deliberately made heads, so that he could strengthen the other two attributes.

Even if someone with a talent like Leng Yuhan awakened at the age of six, it is not easy to obtain 20 points of source power in a low-level world.

But what Wu Fa thought about was only ......

It's amazing to have a plug-in!

Yes, being a wall-mounted is amazing.

Now Wu Fa is overjoyed in his heart, low-level skills can be used, and they are enhanced with the enhancement of his relevant attributes, but there will still be a limit, 'madness' loses its effectiveness, so that Wu Fa gradually understands that skills are not always useful, this is distressing, the system has given him such a big gift!

He didn't even think about it, and directly turned on the 'extinction'.

"Huh?"

Qi Sisi, who was walking with Wu Fa, only felt that her side was empty, and turned her head to look over, Wu Fa was still the same Wu Fa, and there was him in her field of vision, but she always felt that this person was a little ...... Not really.

It seems to be floating in front of you like a virtual one, and it seems to be no different from the surrounding earth, rocks, mud and grass, and there is no sense of existence.

If she hadn't deliberately paid attention, even if Wu Fa was standing by her side, she wouldn't have noticed it at all.

However, this feeling only lasted for a moment, and Wu Fa's whole person suddenly became three-dimensional again, and Qi Sisi blinked his eyes, a little unclear.

"Delusional." She said to herself.

Wu Fa lifted the 'extinction', and his heart was extremely satisfied, compared to the dual use of 'silent step' and 'concealment', 'extinction' obviously did better, worthy of the F+ level.

After tasting the sweetness, Wu Fa naturally did not give up, and spent another 20 points of source power to fuse 'aiming' and 'throwing' together.

"Precision strikes: F+. Front: Strength F+, Agility F. ”

It's another F+ skill, which is also a perfect combination of two skills, and this time, in addition to the effects of the two skills, Wu Fa also has more aiming and control over melee combat, and now even if it is a pinhole, he can use a Tang knife to accurately stab into it!

However, the bigger surprise is still to come, and the system's prompt rings again.

"Fusion Ability ...... Detected"

"Extinction (F+), precision strike (F+). Fusion front: Strength F+, Constitution F+, Agility F+, Spirit F-. Fusion costs 50 Source Power. ”

Can these two skills also be fused?

And the required attributes are abnormally many, and even the spirit is brought with them.

"Lack of source power!"

Wu Fa roared in his heart, he only had 15 points of source power now, otherwise he really wanted to see what powerful skills these two skills could be fused.

After complaining, Wu Fa's eyes scurried around, looking for the mutated creatures in this wasteland, and it was easy to do without source power, so kill a few creatures immediately!

The current Wu Fa is extremely eager for source power, and with the system and plug-ins, it is very easy for him to want source power. Kill, as long as you kill, you can have source power!

……

Half a month later, Wu Fa and others were still walking on this wasteland, and as they went deeper and deeper, more and more steel ruins were found along the way.

After half a month of living in the wasteland, he couldn't wash, couldn't sleep on a soft bed, and barely quenched his hunger and thirst by relying on the so-called marching pills, which made him look a little messy.

I haven't met a creature with a collar for half a month, although Wu Fa pretended to be very ignorant, but as long as a person with a brain will understand that it is a little weird, so Wu Fa also pretended to ask, and Gong Fan's answer was a little silly and said to go again.

If he hadn't been wary in the first place, Wu Fa might have really thought that this was the wrong way, rather than the result of someone deliberately leading the way.

Qi Sisi also began to be anxious, but Wu Fa had a little bit of wind with her at the beginning, knowing that he was suspicious of Gong Fan, so he also forced it not to ask.

So the three of them walked in this weird situation for more than half a month.

"Big brother, there's a mine in front!"

Suddenly, Gong Fan pointed ahead and said loudly.

Far away from the flat land where they were, there was a downward slope, and on the left side of the slope was a gate made of improvised metal and wood, and in the flat ground inside there were tents, and further in, there was a hole.

The key thing is that it is a little far away from them, and if you don't pay attention, it will be easy to miss, and Gong Fan pointed directly at that target from the beginning.

Wu Fa narrowed his eyes and looked near the gate, where stood two tall, dark-green-skinned 'giants'.

The giants were dressed in improvised armor covered with rust, and held what appeared to be a patchwork of guns, straight as sculptures.

Mutant giants

Power: F+

Constitution: F+

Agile:-

Spirit:-

Defense: F+

Resistance:-

Evaluation: Natives who have been mutated by radiation have experienced a rapid increase in physical fitness and a decrease in intelligence.

Although it belongs to the same F-level upper rank as the mutant mad ghost, the mutant mad ghost relies on its immortal physical quality, and the attributes of this mutant person ...... It's a little bit of an explosion.

"Big brother, these are all mutant giants, they are wise, they can be guarded, there must be treasures inside!" Gong Fan danced excitedly, completely with a surprised expression of discovering the treasure.

But Wu Fa knows that this is the main event!
