The Devil of Online Games Comes to the World

Chapter 333
After coming out of the temple, Fang Tian went straight back to the City Lord's Mansion.I consulted Weito, if you upgrade the city to level [-] now, although you can improve the city's defense.However, the number of troops sent by the system will also increase accordingly, which may expand losses in time.Therefore, Fang Tian had no choice but to give up speeding up the city's upgrading and instead speed up the research of science and technology.The reinforcement of the city wall and the reinforcement of the city gate are studied separately, and the arrow tower and the moat are also studied.Considering the time issue, other technologies cannot be researched for the time being.

After finishing these things, Fang Tian teleported directly to Rock Lake City.That's right, it is Rock Lake City, the city where the dwarves live in seclusion.He remembered the cannons that the dwarves used to bombard him back then, which used magic crystals as energy. If there was such a thing placed on his city wall, the effect would definitely be good.

Find the dwarf king and explain to him your purpose.Unexpectedly, the dwarf king readily agreed: "It's good to let you humans see the power of the cannons made by our dwarves, so that we won't be looked down upon by you humans when we return to the ground. But the cost of this thing is currently relatively high, and we can't charge it for free." supply."

"Okay, the price is negotiable. It's just that I hope you can give more of the magic spar." Fang Tian made up his mind that he doesn't need too many magic spar for this battle.However, Fang Tian plans to completely occupy Qinglong City in the future, so he will definitely need more magic crystals.So we have to accumulate slowly from now on, asking for a little each time is better than a lot at once, and it is refreshing for others to give.

"Because the magic spar was not stored at all some time ago, I can't supply you much now." The dwarf king said, "Every ten rounds of the magic cannon consumes one magic spar, and our maximum supply can only provide you with almost every one." [-] rounds of magic spar. Although the cost of the magic cannon is only [-] gold coins, it is due to the lack of magic spar. For your cost-effectiveness, we advise you to only buy [-] pieces."

"Well, let me think about it." Fang Tian asked after a moment of contemplation, "How long does it take for the magic cannon to condense its power? Last time I saw you seemed to have used it for a long time."

"To be honest, the magic cannon you saw last time was a cannon that we have eliminated. It was used to mine devil ore. Now our magic cannon can be fired every second. But considering the production of cannons Due to the difficult heat of the metal material, we usually need to cool down for five seconds after each shot." said the dwarf king.

"Five seconds, that is to say, it can be fired ten times in one minute? If you give me 1 shots, won't it only last for [-] minutes?" Fang Tian was in a dilemma.

"Otherwise, although the cooling is theoretically five seconds, under normal circumstances, after ten consecutive attacks, the magic cannon cannot be used normally due to the increase in the chamber temperature. At this time, a cooling device is needed to cool him down. In general It takes half an hour to cool down," said the dwarf king.

"Then does the cooling device come with the magic cannon?" Fang Tian asked with concern.

"No, the cooling device is not self-contained. Of course, if you need it, we will sell it to you very cheaply. The cost of this cooling device is not high, so you can equip each magic cannon with a cooling device and place it on the city wall." The dwarf king said with a smile.
