Yang Chen didn't expect that he had actually upgraded, it is said that most of the sea clans here are only more than level 20, and there are only a few of them in their 30s, and he is now level 41, and the experience that these sea clans can provide him with is very small.

However, although it is very rare, it is not impossible.

The three fire dragon explosions killed a large number of sea tribes, each of which could provide Yang Chen with a small amount of experience, and in the end, the quantitative change led to a qualitative change, and Yang Chen was upgraded.

After upgrading, Yang Chen's originally somewhat rickety figure stood up again.

Staring at the doorway, watching the sea tribe there pounce on the sea of fire one by one, burning themselves, but they still extinguished a small piece of flame, and as the flames were extinguished more and more, the speed of the sea tribe's attack became faster and faster.

Yang Chen was thinking quickly, although the power of the fire dragon explosion was huge, but it consumed a lot of spirit, which was not very cost-effective for him, he needed to find the best magic, the lethality was big enough, but it would not consume too much of the body, especially the spirit.

Soon, Yang Chen targeted a magic spell, a fireball!

This is an upgraded magic of the big fireball, which can cast more than ten large fireballs at once, and although the explosive power is not as good as the fire dragon explosion, the lethality is not weak.

And more importantly, this is a magic that can be mastered at level forty-four, although the magic power consumed is huge, but it will not cause too much burden on the spirit, and the consumption of magic power is not a matter for Yang Chen at all, in his space ring, there are magic potions.

After thinking about it, Yang Chen didn't wait for those sea tribes to rush to the entrance of the door and began to cast magic.

Fireballs!

Ten seconds later, a series of large fireballs roared into the doorway, and by this time, the sea tribe in the doorway was about to rush to the doorway.

Boom, boom, boom......

With a series of explosions, the sea tribe fell to the ground one by one, but although this explosion sounded even louder, the damage caused was far less intense than that of the fire dragon explosion, so deterrent.

And more than half of the magic power in Yang Chen's body was also drained, and he had no choice but to take a sip of the blue bottle and continue to cast spells.

However, although the power of this fireball is not as powerful as that of the fire dragon explosion, the load on the body is also small.

With the support of the ample blue bottle, Yang Chen could cast this magic almost unlimitedly. Of course, this is only in the best possible situation.

Facing a BUG-level mage who can infinitely replenish demons, the Sea Clan's attack today is destined to be a tragedy.

In the end, with the help of Yang Chen, new fortifications were cast, the gates of the city were blocked, and they were finally reinforced to the point where they were completely unafraid of the Sea Clan's attack.

At this time, Yang Chen had already come to the top of the city gate and began to stand on the city gate to cast spells.

In front of him stood a line of warriors with shields, and even Groot came to his side and began to protect him.

A series of fireballs descended on the Sea Clan's army, countless Sea Clans were blown up and burned to death, and Yang Chen's experience was slowly growing.

Yang Chan also cast a spell attack on Yang Chen's side, Yang Chen did not give her a group attack magic, so she could only cast the ice spear technique with the most powerful attack power, although the lethality was limited, but in the face of those sea clans who were injured by Yang Chen's continuous fireballs, whether they were seriously injured or lightly injured, they were all one shot at a time.

In the process of picking up leaks, Yang Chan's experience was also improving rapidly, and it didn't take long for her to be upgraded to another level.

I don't know how long it took, Yang Chen felt that he was about to vomit when he cast a fireball, and the Sea Clan's offensive gradually stopped, and then slowly retreated backwards.

Looking at the orderly evacuation method of the Sea Clan, Yang Chen became more and more sure in his heart that there must be a commander behind these Sea Clans.

In fact, not long after he climbed the city wall, Yang Chen had this feeling, because he found that the Sea Clan who was besieging the city was obviously different from the Sea Clan he had encountered outside the city before, that is, they were no longer fighting separately, but had cooperated.

For these simple-minded sea clans, it is simply impossible to do without a wise commander behind them.

Yang Chen didn't know that when he was looking at the Sea Clan army from afar, in the Sea Clan army, which was still vast, a Sea Clan with narrow green eyes was also observing him from a distance.

His gaze was filled with hatred and resentment.

As the Sea Clan retreated, the human soldiers on the city walls let out a cheer of victory, and Yang Chen deservedly became the greatest hero of this defense battle, turning the tide in danger.

If there was no Yang Chen, the moment the city gate was breached, Danlot would have fallen, and if it wasn't for Yang Chen, Danlot would not have been able to repel this Sea Clan's attack at all.

No one doubted either of these points, and all paid the highest tribute to their heroes, countless thumbs up, and countless people chanted the names of the heroes.

Yang Chen's name was leaked to ordinary soldiers by someone else, and then he spread all over the city guards with wings.

In the cheers, the city lord Li Del came to Yang Chen, with a complicated feeling, Li Del also offered his respect.

Yang Chen was not used to such a scene, so he just dealt with it hastily, and then returned to Blizzard.

Fortunately, although the Sea Clan suspended its attack, it did not retreat, and it was not yet time to celebrate, otherwise Yang Chen would definitely not have left so easily.

In the mercenary group, Liu Yun was already waiting in a hurry, and when he saw Yang Chen and the others coming back, he hurriedly greeted him and said, "You guys are finally back, how is it outside the city now, have those sea clans retreated?"

Yang Chen said: "The Sea Clan has been repulsed, but it has not been evacuated, and it is estimated that it will launch an attack......

Yang Chen simply told Liu Yun about the war, he thought that Liu Yun had no interest in some things about fighting and killing, but he didn't expect Liu Yun to ask about the details in detail, and then Yang Chan on the side excitedly took over the conversation.

"Sister Yun, let me tell you, my brother is amazing......"

"Wow, the fire dragon is bursting, is it so powerful, are those sea tribes falling one by one?"

"Of course! and ......"

Two women, and very beautiful women, are so interested in discussing the matter of fighting and killing, how strange this meeting is!

While the two women were chattering, Yang Chen called Groot over and asked him to teach Liu Yun some basic fighting qi secret techniques.

The most suitable for Liu Yun to practice is the thunder fighting qi, but the thunder fighting qi secret technique is very rare in the entire Middle-earth world, not to mention a small Danlot.

There is no such attribute of Dou Qi here, so Yang Chen can only let her practice the basic Dou Qi without attribute first, and then let her transfer to cultivation when she has a suitable Dou Qi secret technique. (To be continued.) )
