Fortunately, although Alexander's cultivation is high, his knowledge of chemistry is equivalent to that of a novice, and he can't even distinguish between the words "hydrogen" and "light gas", let alone how to make hydrogen.

But after Zhang Bai was frightened by this shock, he secretly decided that the production of hydrogen must be kept secret, and it was better to move far away to the uninhabited village.

Alexander agreed to only one additional condition, and Rome was responsible for the manufacture of sealed hydrogen barrels. Zhang Bai drew the shape details and approximate dimensions of the barrel according to the appearance of the oil barrel in his previous life, and stipulated that it must be made of iron sheet or pottery.

The Roman emperor was very happy and left the barracks in high spirits and went straight to Peshawar, where, according to him, the construction of barrels was to be started immediately.

He left Zhang Bai, who was in pain and in tears, on the spot.

That night, Zhang Bai, who had received a blow of 10,000 points, was no longer in the mood to cultivate.

In the dream realm of the demon capital, he took out the building wood in the nine-story tower, carefully selected one of the worst woods with tears, and cut and sharpened it like a mad demon to make two short swords.

He inlaid the smallest and ugliest moonstone in the upsetting of one of the swords, intricately carved the gauntlet, and finally carved a symbol in the middle of the pattern, a round and smooth circle.

"Draw a circle and curse you!" Zhang Bai, who was distressed and angry, was about to turn black, he picked up another Jianmu sword without any decoration, and laughed maniacally, "We must get the loss back, we must recover the loss!"

"What are you doing stupidly?" Mu Jing suddenly appeared beside him, looking at Zhang Bai with a strange face.

"Huh, Sister Mujing, are you back?" Zhang Bai was overjoyed, Mu Jing seemed to be early this time, he must have missed himself, he felt much better, and he didn't need to blacken.

"We haven't arrived in Peshawar yet, I'm just entering the dream realm early, the Apostle will be there tomorrow, and there is still a day to go. ”

Mu Jing then asked, "What's going on here? Why is there a large scorched forest in front of you, and what are you doing here with a sword made of wood?"

Zhang Bai immediately told her about Xiaobai and Xiaohei's troubles, getting help from Cisheng, and trading with Alexander to be hated and bargained, and looked at Mu Jing aggrievedly after speaking.

Unexpectedly, instead of sympathizing with him, Mu Jing leaned back and smiled back, and also proposed to meet Xiaobai Xiaohei and Cisheng and others, saying that they were all very interesting.

......

The next day, starting in the morning, on the construction site next to the barracks in the northeast of the city, the preparations were basically ready, and the craftsmen finally began the official construction.

At the same time, on the edge of the big camp in the west of the city, Dedalus Surin specially selected more than a dozen of his cronies and subordinates to come to the Zero and began to learn to sail.

Everything went well, this time the ship was built much faster than the previous one. After all, with experience, Ma Ge's on-site scheduling and preparation work is particularly smooth and robust.

The materials needed were readily available, especially the balsa wood, which surprised Ma Ge very much, and the large pieces of wood were as light as a few pieces of paper in his hand. One or two workers can stack a large pile of wood, and this wood is also particularly convenient to process, and the whole construction period can definitely be greatly shortened.

Fire paint, tung oil, canvas and other materials were also very complete, and Alexander did not hesitate to use the power in his hands, and under his urging, all the nobles and merchants of Peshawar did their best.

There was no shortage of manpower, and Father Sotle came with his son Zabad, as well as almost all the brothers in the beggar's den. Daolao also recruited some craftsmen from the city, most of whom were skilled workers.

Many of these people had previously participated in the construction of the Apostle. They considered the ship they had helped build at that time to be a flying artifact, and they had always been deeply proud of it.

This time, when they heard that they were going to build a spaceship again, these craftsmen came to sign up. Daolao deliberately gathered them together and registered them to learn about their various aspects, and then added some selected new craftsmen to form a core team of craftsmen.

This group of people was already familiar with manufacturing, and they cooperated with familiar people, and the work efficiency was naturally fully opened, and in just a few days, the skeletons of the three spaceships had already faintly come out.

"Well done!" Zhang Bai and Brother Ma watched from afar, "But you still have to find a way to speed up, you and Dao Lao will think of a way together." “

"Okay! We'll do it. Brother Ma agreed to come down with great dignity.

He is now in a position similar to that of the chief engineer, and Zhang Bai gave him an identity called the East Garden Master Zhang. This position is a small official position under the Han Dynasty official "Jiang Zuo Dajiang", which is actually equivalent to the royal carpenter. Zhang Bai was not an official of the Han Dynasty, so he did not count the official positions privately, so he didn't dare to publicize it, so he gave him a petty official.

However, this position still sounds good, and Ma Ge happily accepted the position and is devoting himself to his work.

"I need to go to the temple, and I'll leave it to you. ”

"Don't worry!"

After Zhang Bai finished explaining, he rode with Mu Jing to the west gate of Peshawar.

On the way, he also muttered to Mu Jing: "You said that Brother Ma, is he an official fan? Last time, Dadhebon gave him the position of centurion in the army, he was so excited, this time it is like this again, what do you say?"

"I don't know, I'm not interested in being an official at all!" Mu Jing replied.

"Of course, you're a fairy, of course you're not interested, I mean that brother..."

"You're still interested in managing others? Didn't you say you wanted to recoup your losses from Alexander? And you said it viciously. ”

"That's right! In fact, after a few days, Zhang Bai's mad spirit has almost disappeared, and the materials sent by the Romans in the past few days are usually difficult to complete, Zhang Bai feels that his heart is a lot more balanced.

"Ahem... I still have a lot of things to talk to Alexander, and he's going to be cheated back by me... Hey, hey!"

......

Peshawar City, next to the Kabuli Gate, has now become a large market, crowded with people buying and selling.

This is all because of the appearance of the temple, which made Zoroastrian believers gather from all over the world, and because of the breathtaking bronze statue of the goddess with its tall and tall materials, it is even more famous.

What's more, the temple was inhabited by the old god Sharama, who also treated people for free, so more people came.

The inside and outside of the temple are now crowded with people, and although the believers do not dare to make noise in the temple, there are too many people after all. Therefore, except for Nanhua and Yuji, who needed to heal the believers, and the Roman doctor Titus, the rest of the air regiment was moved to the Suraj mansion.

Speaking of which, this Suraj Mansion is actually located on the west side of the city, not too far from the Kabuli Gate. Although the basement of the mansion was blown up, the buildings above ground were fine, and the loyal white horse in the mansion was still wandering around the courtyard.

This is the home of the Sangha Society. As soon as he returned, he naturally helped everyone tidy up their rooms, clean the courtyard, and prepare meals, much to the embarrassment of Jinchi and Hetri, who had come with him.

Lingling didn't care, he was also used to being alone since he was a child, so he immediately took a stone axe, helped the monk cut a pile of firewood, and helped him make a fire in the stove pond, and then happily looked for the little black and white pigs to play with them.

Mu Jing and Zhang Bai arrived at the temple first, and saw that the three doctors were busy, so they hurriedly retreated in order to avoid being caught.
