I am the son of the Dragon God in Douluo Continent.

Meanwhile, in the conference room of the Spirit Tower, Xu Xingyu had just received news from the messenger about the Reverse Spirit Alliance accepting the challenge.

This prompted Xu Xingyu, who was drinking tea, to look at the letter in her hand and exclaim, "They replied so quickly; it seems they were in a hurry too."

Ma Xiaotao chimed in, "Isn't this obvious? After all, you deliberately wrote such angry words in your mind, how could they not be so furious that they just agreed in a fit of anger?"

When Xu Xingyu wrote this letter, Ma Xiaotao only glanced at what the other party had written. As for what it said, well…

It's more like a provocative letter than a challenge letter. Although the envelope didn't contain a single swear word, the content it conveyed was far more provocative than any insult.

The other women who had read the letter agreed with this view. No matter how well-mannered a person is, it is almost impossible for them to resist getting angry when reading such provocative content, unless that person is a so-called saint.

Just then, Gu Qiuxi suddenly spoke up, "Brother Xingyu, was it necessary to write it so drastically? Although I also dislike those ignorant fools, won't it cause some trouble if we want to win them back later?"

Upon hearing this, Xu Xingyu waved her hand and said, "I have no intention of subjugating them. You know, our Spirit Pagoda has expanded too quickly in recent years. The number of affiliated families and forces has also started to increase. So for now, we should temporarily halt this expansion and focus on developing and promoting soul guidance technology and soul spirit technology."

"Adding more would be detrimental to the Spirit Tower at this stage. After all, apart from the Spirit Tower's direct descendants, we can't say that we have 100% control over the hearts and minds of other forces. So it's better to take this opportunity to properly digest the Spirit Tower's existing power."

"I see." Gu Qiuxi was beginning to understand Xu Xingyu's intentions, but then something seemed off, so she asked, "But did it have to be such a provocative and aggressive way of provoking her? Couldn't she just write a letter?"

"Of course, I had my own considerations for writing it that way," Xu Xingyu analyzed confidently. "My main goal was to create the impression of a young upstart for the so-called Reverse Spirit Alliance. They would think that I'm arrogant, disrespectful to elders, and impulsive. This would make it easier for them to believe that this is just me acting arbitrarily because of the power Sister Nana gave me, making it easier for them to accept the challenge I issued to them."

In response, Ma Xiaotao retorted, "Are you sure it's not simply because you're getting impatient with the people from the Reverse Spirit Alliance coming to your door every day that you did this?"

"I'm not that childish!" Xu Xingyu retorted irritably. "If that were really my main reason, what kind of manager would I be?"

After saying that, he added in his mind that this reason was a secondary one. The main reason was to establish the prestige of the Spirit Tower and to make an example of them. There really was no other reason.

To this, Ma Xiaotao shrugged and said, "Let's just assume that's how it is."

Then, as if remembering something, he suddenly asked, "By the way, are Xiaoxue and Xiaoxiu going to that so-called Earth Dragon Gate Secret Realm?"

"Yes, that's right." Xu Xingyu nodded and said, "After all, there is not only the Ten Thousand Year Profound Ice Marrow that can help them cultivate yours, but also the Ice Extreme Divine Crystal that can be used as materials for their battle armor."

"Battle Armor? Is that what you were talking about before?" Ma Xiaotao asked curiously, "Does this so-called Battle Armor really have such strong support capabilities?"

Since confirming her relationship with Ma Xiaotao, she has also begun to learn about some core soul guidance technologies of the Spirit Pagoda, including the research and development of battle armor.

When Ma Xiaotao heard about the development of battle armor, her first reaction was disbelief. After all, a soul guide armor that could allow a soul master to fight two levels higher was unheard of!

If this thing is successfully developed, the world of Soul Masters will usher in a brand new revolution!

Of course, they were equally shocked when they heard about the development of mechs, since theoretically, if there were no battle armor, these so-called mechs might be able to directly replace the Soul Master group in the future.

In response to Ma Xiaotao's question, Xu Xingyu simply smiled and said, "If you don't believe me, why don't you find an opportunity to try it out?"

"Trying? Could it be that you made battle armor for me?" Ma Xiaotao exclaimed in surprise.

Xu Xingyu simply maintained her smile and continued, "It's not just you; Xue'er, Dong'er, Qiu'er, Nan'an, and Jiu Jiu have all prepared their own battle armor. Although some are not yet finished, the general designs are complete. Fortunately, yours is already finished."

There was no other way; after all, these were the girls Xu Xingyu loved dearly, and it would be unreasonable not to provide them with protective armor.

As for why a copy wasn't made for Gu Yuena, it's mainly because if Gu Yuena were to wear battle armor, it would need to be at least at the level of a four-word battle armor, and Xu Xingyu at this stage is unable to create battle armor of that level.

After all, he was still exploring the Soul Forging technique, so the battle armor currently being developed by the Spirit Pagoda was all at the one-word or two-word level.

The reason Ma Xiaotao was able to finish it so quickly is mainly because some of the materials used in Ma Xiaotao's battle armor overlapped with those used in Xu Xingyu's own battle armor. So, after Xu Xingyu finished her own battle armor, she conveniently finished Ma Xiaotao's battle armor as well.

Xu Xingyu's battle armor uses Sun Essence Gold, Lunar Crystal Core, and Star Silver as materials for its components, and a Sun and Moon Divine Stone as its core to power it.

Because Ma Xiaotao's martial soul has evolved into the Vermilion Bird, the materials she uses are concentrated in fire attribute, positive yang, and materials with the reincarnation attribute.

Therefore, the solar essence that Xu Xingyu had used for his battle armor came in handy at this time. In any case, he had used a lot of solar essence for spiritual forging practice in order to make the battle armor, so there was a lot left over that he could give to Ma Xiaotao, which can be considered to make the best use of it.

Just a few days ago, he learned from the top mecha makers at Shrek City headquarters that Ma Xiaotao's battle armor had been completed and that they were sending it and Xu Xingyu's battle armor to the Dragon City Qiling Tower.

The upcoming battle against the Reverse Spirit Alliance will provide a good opportunity to examine the true power of these two battle armors.
