Early the next morning, Meng Chen summoned blacksmiths, carpenters, leathermen, swordsman instructors and others to the library to discuss countermeasures.

When everyone arrived, Meng Chen spoke first: "I have gathered everyone together in the hope that we can gather everyone's wisdom and solve a problem that the City of Hope is currently facing. The development of the city requires metal resources, but the most likely location in the vicinity where metal resources exist is occupied by a group of powerful and powerful vajra orangutans. What do you think we should do to deal with or expel this group of orangutans? ”

As soon as Meng Chen's words fell, everyone began to whisper.

It didn't take long for the head chef to speak, "My lord, maybe we can use food to lure these vajra orangutans away. ”

Meng Chen asked, "What if this group of vajra orangutans went back after eating the food?" ”

"Uh......" The head chef was speechless when Meng Chen asked.

A swordsman instructor proposed, "My lord, we can recruit more soldiers and kill all of these vajra orangutans!" ”

Meng Chen shook his head and said, "With the current funds of the City of Hope, it is not enough to recruit a large number of soldiers!" Moreover, the Vajra orangutan is very powerful, and if it is attacked head-on, it will cause heavy casualties. That's what I don't want to see! ”

One of the blacksmiths said, "My lord, we can make powerful weapons and kill these vajra orangutans!" ”

Meng Chen asked, "What kind of weapon can be made to kill the Vajra orangutan?" Do you have a plan? ”

The blacksmith shook his head and said bluntly, "No! ”

Such a crisp answer made Meng Chen roll his eyes.

Everyone discussed for a long time, but they have not been able to come up with a feasible plan.

Just when Meng Chen thought that today's meeting might end here, Ellie interjected, "Lord Lord, can you make a huge longbow and shoot this group of vajra orangutans from a long distance, so that it won't cause too many casualties." ”

"Isn't this a bed crossbow? If you can really produce a bed crossbow, it will be possible to deal with this group of vajra orangutans. But...... In the game, first-order towns do not seem to be able to make bed crossbows, unless there is a bed crossbow blueprint. Meng Chen said secretly in his heart.

Meng Chen asked the carpenters, "Can you make such a big bow?" ”

After the four carpenters discussed with each other, one of the carpenters replied, "My lord, if you want to make a huge longbow, you must first have high-quality materials. The bow can be enlarged and thickened to solve the problem of accumulation, but we do not have a strong enough bowstring material. ”

Meng Chen asked, "Could it be that the tendons of the four-horned monster cow are not strong enough?" ”

The carpenter shook his head, "Not enough! ”

Just as Meng Chen had a headache about the bowstring material, Ellie said, "Lord Lord, can you let me try it?" ”

"Ellie, do you have a solution?" Meng Chen was surprised.

Ellie replied, "You don't know until you try!" ”

Since Ellie wanted to try, of course Meng Chen would not refuse, and immediately said, "Then please, Ellie!" All the materials in the City of Hope are available to you as you like. ”

"Hmmm! I won't let you down, my lord! Ellie nodded in response.

Afterwards, Meng Chen asked the carpenters, "If the problem of bowstring materials can be solved, can such a big bow be made?" ”

The carpenters looked at each other and replied, "In addition to the material, the structure of the great bow is also very important, otherwise ordinary people would not be able to pull the bowstring at all!" ”

Meng Chen thought for a while and said, "Can you install a pulley block and a winch?" This will save a lot of effort! ”

"What is a pulley block and a winch?" The carpenters asked, confused.

Meng Chen explained a little about the principle of the pulley block and the winch, and drew a sketch of an imaginary bed crossbow.

Since he didn't know the structure of the bed crossbow, whether the bed crossbow produced according to the sketch had any effect or not, Meng Chen didn't know whether it was effective.

Looking at the sketch of the bed crossbow drawn by Meng Chen, the carpenters said with a skeptical expression: "Is this really possible?" ”

Meng Chen replied uncertainly, "Uh...... It should work! ”

At this moment, a scholar suddenly spoke: "My lord, you should have drawn a sketch of the structure of the bed crossbow. There are materials in the library, and if you give us some time, we can make improvements to this sketch design! ”

"Really?" Meng Chen asked in surprise.

The scholar nodded and replied affirmatively, "It should be fine!" ”

"Great!"

Just when Meng Chen was ecstatic, an electronic synthesis sound sounded in Meng Chen's mind, "Ding Dong!" May I ask the player Meng Chen, do you consume 100 gold coins to improve the design drawings of the bed crossbow? ”

......After receiving the prompt tone, Meng Chen was speechless, and said secretly in his heart: "Could it be that this is the correct usage of libraries and scholars - exchanging krypton for time?" ”

Can Meng Chen refuse this?

Of course not!

At this time, Meng Chen's resource space only had 72 gold coins left, which was not enough to pay for the improvement of the design drawings of the bed crossbow.

"Looks like we have to go to the market!" Meng Chen sighed secretly.

Afterwards, Meng Chen announced the end of the meeting, and everyone left the library one after another.

The market is a stone building with a length of 40 meters, a width of 30 meters, and a height of more than 10 meters.

The interior of the market is quite empty, and the walls around it are covered with various signs indicating the trading ratio of various resources.

The panel, which was supposed to show nearby cities, only showed the name of one city, the City of Hope.

Although he planned to exchange resources for gold coins, Meng Chen didn't plan to exchange too much, after all, the trading ratio was too dark, and the more he exchanged, the more he lost.

At present, there is a surplus of food in the City of Hope, which can be exchanged for gold coins.

200 grain (gray) = 1 gold coin;

200 grain (white) = 3 gold coins;

The proportion of white quality grain is three times that of gray quality, and Meng Chen chooses to use white quality grain for trading.

Due to the hunting of medium-threat creatures in large quantities some time ago, there are 54,000 units of white quality grain in the warehouse of Hope City at this time.

Meng Chen came to the warehouse and ordered the coachman to immediately transport 10,000 units of white quality grain into the trading market.

Watching a cart of grain being sent into the trading market, Meng Chen's heart ached, "Selling 10,000 grains (white) can only get 150 gold coins, and buying 10,000 grains (white) will cost 3,000 gold coins, such a trading ratio is too pitiful!" ”

30 drivers can transport 2,000 units of grain (white) per trip, and 10,000 units of grain (white) need to be transported back and forth five times.

An hour later, a message popped up in the light curtain in Meng Chen's mind, "Food (white) -10,000, gold +150!" ”

Back in the library, Meng Chen gave an order through the light curtain in his mind, "Improve the design drawings of the bed crossbow!" ”

"Gold -100, improve the bed crossbow design drawings begin! After 72 hours, the improvement is complete! ”
