After the main part of the magic drive was completed, the rest of the work was a matter of course, and the tailors worked overtime overnight to sew an oval canvas balloon, and the smiths used the lightest metal to create a double hull several meters long and wide.

Haoren used the spider silk ring to shoot the spider silk, tied together with dozens of them, and linked a whole circle around the canvas hot air balloon and the hull, and at least 100 people would not fall while sitting in the hull.

The last part is the installation of the magic guide drive, according to Wang Han's opinion, a drive is installed on each of the four corners of the hull, and a high-grade lava spar is placed in each drive, providing a steady stream of fire energy, which is enough to ensure the rapid expansion of the hot air balloon into the air.

Four additional Magic Drives were installed at the tail of the hull, each containing a fine-grade lava hedron to propel the massive and heavy hull high in the air.

Regarding the tail drive, Wang Han and the major and others had an argument, and the major felt that only two drives needed to be placed, and four were completely wasteful.

Wang Han was adamantly opposed, as a power driver for flight, if the number was reduced, the longer it would take to pass through the spider monster, the greater the risk they would have to take.

According to Wang Han's calculations, the maximum altitude that this magic hot air balloon can fly is about one thousand meters, and it is kept at seven or eight hundred meters for safety reasons, and the maximum range of the spider silk and corrosive slime of those giant spiders outside the fortress is four or five hundred meters, which is within the safe range.

Haoren is on Wang Han's side, because no one knows if a new type of spider monster will emerge, or if the spider monster under the city will suddenly have an evolutionary mutation and have a longer range attack.

There is only one magic hot air balloon, and if you want to make a second one, on the one hand, there is not enough time, and more importantly, there is not enough lava spar to provide the power source. In the end, the major adopted Wang Han's advice and adopted four drives as power equipment.

Wang Han proudly showed off to the others: "According to my calculations, it only takes twelve or thirteen minutes to escape from the spider tide above the fortress and fly into a safe area!" ”

"How does it feel faster than an airplane! And according to what you said, you have to carry 100 people at a time, such a large weight, is it really so fast? Someone took a look at the endless spider frenzy outside the fortress, and some suspected that Wang Han's words were too exaggerated.

Wang Han turned red and defended loudly: "Don't forget that it's the exquisite-grade lava spar that is providing power now!" For example, if the energy of a primary lava crystal is 1, then the energy of a delicate grade crystal is 1000, a thousand times! Theoretically, it is not delusional to rival the speed of an airplane! ”

The major also helped at the right time, he pointed to the circle of defense towers on the fortress, and said, "There is only one primary energy crystal installed on the top of those magic defense towers, I think everyone knows how powerful it is." ”

With this explanation, everyone no longer had any doubts, they had no concept of the energy level in Wang Han's mouth, but they had a deep understanding of the power of those defense towers.

Everything is ready, just wait for the final test flight to begin.

"I really want to thank you for your help this time!" The major pulled Haoren into a remote corner and thanked him sincerely.

Haoren waved his hand and said with a smile: "Thank you Wang Han!" If it weren't for his idea, I'm afraid everyone would really have to risk their lives to break out! ”

"Wang Han, I naturally want to thank him, but the price you paid is too great!" The major's face was serious, as if he was hesitating about something, and after a while, he seemed to have made up his mind, and said in a deep voice: "Since you are going to leave in a hot air balloon, there are many things in the fortress that cannot be taken away. ”

Haoren nodded and said: "That's for sure, when the time comes, everyone can't carry anything except their own equipment, which can reduce the quality and ensure a little more safety." ”

"There are still some explosives in the fortress, I plan to stay for the last batch and leave, and then detonate the explosives, so that those spiders can go to hell!"

"Great idea!" Haoren couldn't help laughing.

The major looked a little strange and said playfully: "But there are still some things left in the fortress, and it would be a pity if they were blown up like this." ”

The mysterious expression of the major, who has always maintained a rigorous appearance, made Haoren can't help but be curious, and asked, "What is it?" ”

"Strengthened Crystal!"

"Strengthened hedrons? Strengthen the hedron! Haoren's eyes lit up, as a specially built military fortress, it was normal to store some strengthening spars, and he couldn't help asking, "How many reserves are there?" ”

"More than two thousand, the exact amount is not very clear."

Haoren gasped and couldn't help but exclaim softly: "More than two thousand pieces!" My God, have you collected all the strengthening crystals from everyone in the fortress? ”

The Major explained, "Another purpose of Riesling's fort construction was to store a certain amount of fortification hedron in each fort in case it was needed. ”

Haoren asked curiously, "If this fortress hadn't been besieged, what would have been done with these strengthening crystals?" ”

"Transported to the headquarters and let Riesling be deployed in a unified manner."

Haoren opened his mouth, paused for a long time, and muttered in a low voice: "No wonder the combat power of the Lei Army is so high, it turns out that it was strengthened with so many strengthening spars." ”

As Haoren once expected, ordinary people don't have his good guy moments, and if they want to strengthen high-level equipment, they either rely on character and luck, or they can use countless strengthening crystals to strengthen it at any cost.

The major continued: "This batch of strengthening crystals has been stored for more than half a month, and it was originally intended to be sent to the headquarters together, but it turned out that it was besieged by spiders, and it seemed that there was no way to transport it away, and it would be a waste to keep it, so it would be better to share it with you and Jiang Junqing." ”

Haoren narrowed his eyes slightly: "Why are there only two of us, but there are still tens of thousands of people in the fortress." ”

The major sighed: "These enhancement crystals are all mined in the nearby mountains, you probably don't know, ordinary energy crystals are often accompanied by some ordinary strengthening crystals. ”

Haoren understood, and said: "More than 2,000 yuan is allocated to 20,000 or 30,000 people, and it can't be distributed at all. ”

"Yes, the siege of the spider monster has made everyone united, I really don't want to let everyone fight because of this trivial matter, but fortunately, this group of people in the fortress came in later, and they didn't know the strengthening crystals in the warehouse, and the key has always been with me." The Major took out a bronze vintage-style key from the space package and handed it to Haoren.

"You and Jiang Junqing are both heroic professions, take risks to help us, I don't have anything to get my hands on, these strengthening crystals should be my own gifts to you!"

"Thank you very much!"

For Haoren, this is a very timely gift, after just changing into the Glory Suit, because there is not enough strengthening spar strengthening equipment so far, his combat power has plummeted to more than three thousand, which is only a few hundred higher than the Lei Army.

That night, Haoren found Jiang Junqing and conveyed the Major's words to him, since the Major handed over the handling of this batch of strengthening crystals to the two of them, it was necessary for him to discuss it with Jiang Junqing first.

The big boy was silent for a long time, sighed heavily, and while rubbing the big sword in his hand, he said, "He's a good man!" ”

Haoren almost choked in one breath, and said with a slight annoyance: "I'm not asking you to evaluate the major's personality, I'm asking for your opinion, how do you plan to deal with it, the space package will definitely not be able to fit so many spars, not to mention that the weight is too big if it is transported away, and it is also attention-grabbing." ”

Everyone's space package generally only has a capacity of a few dozen grids, and each spar has to occupy a space grid, and it is really unrealistic to stuff more than 2,000 spars into the space package.

Jiang Junqing is not a person who can make up his mind, and looked at Haoren hesitantly: "You mean, we will start directly strengthening the equipment tonight and use up all the spars?" ”

Haoren snapped his fingers: "That's right, this is the only way, it's much better than throwing the hedron to the spider monster for nothing." ”

"My equipment is only level four or five, if you want to continue to strengthen it, you will consume more than a little bit of strengthening spars, are you sure that more than two thousand strengthening spars are enough for us to use?"

"Enough, totally enough!" Haoren's smile was bright, and he said, "But you need to hand over all the equipment to me for strengthening, believe me, I will return you a full set of 12th-order strengthening equipment." ”

Jiang Junqing's eyes gradually widened, his face was full of shock, and after a long time, he reached out and touched Haoren's forehead, and muttered: "I don't have a fever, why did you suddenly start talking nonsense?" ”

Haoren rolled his eyes, shook off Jiang Junqing's cold palm, and said angrily: "In the end, it will not work, give an accurate answer, don't worry, I won't cheat you." ”

"You're serious!"

"I don't have time to joke with you right now!" Haoren paused and added with a serious face: "But I can say it, I am sure to help you strengthen a full set of 12th-order equipment, but this is not for free. ”

"Is there any cost?"

Haoren pondered: "Actually, I have a skill that can increase the success rate of reinforcement, but the cooldown time of this skill is very long, and it takes 30 days to complete the cooldown, so I need at least some in exchange for compensation." ”

The hidden skill is not to be revealed to anyone at any time, so Haoren decided to make up a lie, a skill that can only increase the success rate of enhancement, so that it sounds more credible.

This is also the excuse that Haoren has thought of a long time ago, the 12th-order combatant suit he replaced can't just be placed in the space package to occupy a seat, and it's a pity to throw it away, so it can only be sold at a high price.

I'm afraid that there is no Tier 12 equipment in Jinling City yet, so Haoren needs a reason as an excuse for himself to convince others that although he has a skill to increase the success rate of enhancement, the long cooldown time limits the play of this skill.
