The Thunder Dragon left Fan Wu's left hand and appeared in the first world, and its current appearance was very different from when it had just been summoned.

The original brontosaurus was more like a snake with no obvious head and tail, with a mouth and anus at both ends, and there were no special highlights on its body.

The appearance of the Brontosaurus that appears now is basically the same as a normal snake, with an unusually beautiful purple body, but the head and tail are black, with a total length of more than 2 meters, which is extremely beautiful.

And above its head, like the insects on the other side, there are two small antennae, but they are still small, and they look like just two small sarcoma-like protrusions.

After it left Fan Wu's body, the thunder dragon tattoo on his left hand disappeared, only those black lightning lines remained, Fan Wu tried, and sure enough, he couldn't use the thunder and lightning attack, but the black lightning attack was not affected in any way.

On the contrary, because of the lack of lightning attacks, the black lightning attack appears more pure, and less energy is lost in the release process, and the power is further improved.

When the thunder dragon left, it appeared directly on the ground a few meters in front of Fan Wu like a teleportation, and when it landed, it directly faced the approaching disgusting insects.

Although the thunder dragon had already opened his mind, he did not have as many thoughts and concerns as Fan Wu of the divine power human, and he did not hesitate to attack after landing.

Moreover, the characteristic of the summoned creature of the Thunder Dragon is that no matter what level it is, as long as Fan Wu does not have a specific hit, he will spontaneously use the strongest attack method at this stage.

Therefore, Fan Wu immediately saw what a chain lightning attack was, and saw the thunder dragon open its mouth and send out a purple lightning as thick as a finger towards the nearest bug.

It was like a substantial lightning bolt that instantly scorched this insect first, and then directly vaporized, and the whole process did not take more than a second, which was quite domineering and powerful.

But Fan Wu shouted in his heart that it was a pity, because he felt that it was not necessary to deal with a bug of this strength with this level of attack at all, not to mention that such lightning would definitely need to consume a lot of energy.

Even if the Thunder Dragon can launch such a lightning attack infinitely, it is really a bit inefficient, and it is better to attack directly with the power grid like before, at least it can attack a large area at once.

If you use a range attack like the power grid, at least one move will invert a few meters of insects within a radius of a few meters, and the entire approach bridge is only twenty meters wide, and several power grids can be thrown out in a row to empty a section of the bridge deck.

Fan Wu's thought process was only a matter of a moment, and when he finished thinking and wanted to remind the thunder dragon that he might need to change his attack move, he saw the follow-up and true power of the thunder dragon's chain lightning move.

After the first bug was vaporized, the purple lightning on its body did not disappear, and it seemed that it didn't even consume much, and then this lightning bolt continued to shoot towards the bug next to it, and the bug next to it was the same as the first one before, and it was directly vaporized without any reaction.

Then the purple lightning bolt continued its actions, vaporizing one worm and immediately shooting the next one, and then the next...... And it seems that his speed is constantly accelerating.

The speed of purple lightning increases a little for each bug killed, and the consumption is still very small, and after killing dozens of bugs, the size of the lightning is almost the same as at the beginning.

Under Fan Wu's dumbfounded reaction, the purple lightning continued to accelerate and shoot down to the next worm, and soon covered the entire cross-section of the approach bridge.

There was a gap on the bridge deck, but no bug corpses were left behind, as the purple lightning had vaporized them all, and the lightning energy was far from exhausted after covering one side of the bridge, and continued to attack the nearest bug.

The speed was getting faster and faster, and Fan Wu's eyes gradually couldn't keep up with the attack speed of the lightning, just watching the insect swarm on the bridge surface decrease one by one.

Fan Wu's expression went from unexpected to unbelievable, and then became quite happy in the back, Lei Long's chain lightning move was really domineering enough, and it was completely cleared at this moment, no wonder it was a level 15 skill, which was much more terrifying than the power grid.

After clearing the insect swarm of more than 10 meters, the purple lightning finally began to show its decline, and the speed was still getting faster and faster, but Fan Wu saw that the size of the lightning had shrunk to half of the size at the beginning, and it continued to shrink to the extent that it was visible to the naked eye.

When it was 12 or 3 meters away, the purple lightning finally disappeared silently when it didn't know how to vaporize the first few hundred insects.

"I'll go!"

Fan Wu couldn't help but sigh very connotatively, and simply sat on the bridge and looked at the two sides of the battle boredly, because the thunder dragon had no intention of stopping after the first chain lightning disappeared, and immediately sent out the second one.

It was another 10-meter void, and although the insects kept pouring towards the bridge, a thunder dragon kept them all 20 meters away.

Because Fan Wu didn't want to get up and follow to supervise the battle, he ordered the thunder dragon to slow down the release of the chain lightning and keep the opponent within a range of about 20 meters.

The Thunder Dragon strictly executed the battle instructions given to it by Fan Wu, and no insect could cross this line of death one step and be wiped out.

Taking advantage of this gap, Fan Wu and Thunder Dragon communicated through brain waves, knowing that although its chain lightning skill was huge, it could only be sent out once at the same time, and it could not be released a second time before the previous lightning was completely consumed.

This setting made Fan Wu a little regretful, but at the same time, he felt that this was the right thing, otherwise it would be too much if a skill with such a huge power and such an exaggerated coverage area could be released multiple times at the same time.

After solving this battle puzzle, Fan Wu asked about the thunder dragon without a word, but because the thunder dragon had just opened his mind, there were many times when he still couldn't fully understand what Fan Wu meant, or some things about himself couldn't be explained clearly.

This Fan Wu can also understand, just like an adult wants to ask a child a few years old questions, he can give you a response, but he may not be able to fully communicate.

There is no way to do this, I can only hope that in the future, as the level of the thunder dragon increases, the intelligence can also grow at the same time, and it will be much easier to communicate.

However, most of the questions that the thunder dragon couldn't say clearly focused on its origin and the situation in the world where it was originally located, and some things about its own growth level were relatively clearly described.

Especially what Fan Wu wanted to know the most about the conditions required for its upgrade, the thunder dragon gave a fairly positive answer, in fact, the conditions for it to keep upgrading are very simple, it just needs to keep fighting.

Although it didn't know what the reason for this was, Fan Wu guessed that it was nothing more than energy accumulation and experience accumulation, similar to the experience bar of previous games.

However, in addition to leveling up, Brontosaurus also mentioned that there is a problem about skill development that is not so simple to achieve.

For the Brontosaurus group, electric shocks are basic abilities that can be mastered naturally without any additional conditions, but all other skills require additional stimulation to master.

Because they do not have the same learning ability as humans, they cannot acquire skills through observation and learning, and can only obtain fixed skills given by racial talent through external stimuli.

The power grid is one, and so is the chain lightning, which tells Fan Wu that the previous mastery of the power grid was generated by absorbing the energy stimulation from Fan Wu's body, and the chain lightning this time was caused by the black smoke stimulation absorbed in that strange space.

They themselves can't master innate skills through learning, but the skills they have mastered can be learned by summoners, like the previous low-level skills Grid has already been mastered by Fan Wu.

Even if the thunder dragon is not on his body now, Fan Wu can still use the energy of black lightning to use the power grid, but Fan Wu did not acquire it through learning, but naturally mastered it because he directly collected the thunder dragon into his body.

This is much faster than learning slowly, but this is also the convenience created by Fan Wu's coincidence, and other summoners may not have the opportunity to do this in their lifetime.

After learning this, Fan Wu felt that his luck seemed to have come back a little, otherwise such a good thing would not have fallen on his head.

After knowing some basic information about the Thunder Dragon, Fan Wu decided to try to keep the Thunder Dragon outside for a long time, so that it could upgrade as soon as possible.

According to the Thunder Dragon, their race's innate skills appear every 6 levels, the power grid is the ability it mastered at level 6, and the chain lightning is the skill at level 12, but because it has risen several levels in a row in its sleep, it will not appear until it wakes up.

Fan Wu is now very much looking forward to the Thunder Dragon's promotion to level 18, because not only may a new high-power skill be activated, but also the Thunder Dragon said that level 18 is a level for their strength to improve, and if they can pass it successfully, there will be a very big qualitative improvement.

Therefore, Fan Wu very much hopes that the Thunder Dragon can be upgraded to level 18 in the short term, and is also trying to see if he can find a new energy type to stimulate the growth of the Thunder Dragon, so that it can successfully master the talent skills at level 18.

Although the thunder dragon himself didn't know what the level 18 could only be, Fan Wu was fully convinced that this level 18 skill would definitely be a bigger surprise after seeing the power of the chain lightning.

The key is that if the thunder dragon can be successfully mastered, it is equivalent to Fan Wu can be mastered, because he does not need to spend time learning at all, according to the judgment of the thunder dragon, their current integrated summoning relationship, as long as Fan Wu uses the convenience of his left hand a few more times, he can successfully master the skill.

It is equivalent to Fan Wu's own cultivation and growth, and at the same time, there is a loyal combat partner who is desperately improving, and at the same time, he helps Fan Wu practice thunder and lightning skills for free, which can greatly save Fan Wu's time to improve his strength.

Let him be able to take the lead in the next battles, if there is really any fate to save the world, then it is even more necessary for him to improve his strength as soon as possible to deal with the variables that will arise in the future.
